  The ROM 103 is configured to use a memory (i.e., a non-volatile storage unit) such as a NOR type flash memory or a NAND type flash memory which does not require an external power supply for storage, as a read only memory. The ROM 103 stores various control programs executed by the MPU 102 and fixed value data.

  The RWM 104 is configured to use a memory (i.e., volatile storage means) that requires an external power supply to store and retain SRAM, DRAM, etc. for reading and writing, and allows random access and is identical The time required for reading is earlier than that of the ROM 103 when compared with the data capacity of The RWM 104 temporarily stores various data and the like when the control program stored in the ROM 103 is executed.

  In addition to the above elements, the MPU 102 or the main control board 101 is provided with an interrupt circuit, a timer circuit, a data input / output circuit, and the like. The fact that the ROM 103 and the RWM 104 are integrated into one chip with respect to the MPU 102 is not an essential configuration, and each may be configured as an individual chip.

  The MPU 102 is provided with an input / output port. To the input side of the MPU 102, a power failure monitoring board 105, a payout control device 97, various winning detection sensors 106a to 106h, a magnet detection sensor 109, and the like are connected.

  A power and emission control device 98 is connected to the power failure monitoring substrate 105, and power is supplied to the MPU 102 through the power failure monitoring substrate 105. Further, based on the detection results of the various winning detection sensors 106a to 106h, in the MPU 102, a winning determination (entering determination) for each ball entry portion is performed. Further, the MPU 102 executes a big hit lottery based on the winning on the upper operating port 33 or the lower operating port 34, and executes a support lottery based on the winning on the through gate 35.

  Further, the magnet detection sensor 109 is installed on the back side of the game board 24 around the upper operation opening 33. As described above, since the upper actuation opening 33 serves as a trigger for the internal lottery, the magnet is brought close to the vicinity of the upper actuation opening 33 in front of the window panel 62, and the act of trying to induce the gaming ball to the upper actuation opening 33 illegally is assumed. On the other hand, the provision of the magnet detection sensor 109 makes it possible to detect an illegal act using the magnet. The MPU 102 specifies the presence or absence of the occurrence of the fraud based on the detection result of the magnet detection sensor 109.

  The power failure monitoring substrate 105, the payout control device 97, and the sound light control device 82 are connected to the output side of the MPU 102.

  For example, a winning ball command is output to the payout control device 97 based on the result of the winning determination on the ball entry unit. The sound and light control device 82 outputs various commands such as a variation command, a type command, a final stop command, an opening command, and an ending command.

  In addition, on the output side of the MPU 102, the variable winning drive unit 107 that opens and closes the opening and closing door 32b of the variable winning device 32, the item driving unit 108 that opens and closes the electric role 34a of the lower operation port 34, and the main display unit 43 The character display 44 is connected. The main control substrate 101 is provided with various driver circuits, and the MPU 102 executes drive control of various driving units through the driver circuits. Moreover, although description by illustration is abbreviate | omitted, light emission control of the 1st pending light emission part 45 and the 2nd pending light emission part 46 is also performed by MPU102.

  The power failure monitoring board 105 relays the main control board 101 and the power supply and emission control device 98, and monitors the voltage of the DC stable 24 volts which is the maximum voltage output from the power supply and emission control device 98. The payout control device 97 performs payout control of the winning balls and the rental balls by the payout device 96 based on the winning ball command input from the main control device 81.

  The power supply and launch control device 98 is connected to, for example, a commercial power supply (external power supply) in a game hall or the like. Then, based on the external power supplied from the commercial power supply, the main control board 101, the payout control device 97, etc. generate necessary operation power for each, and the generated operation power is supplied through a predetermined power path. Do. The power supply and launch control device 98 is responsible for the launch control of the game ball launch mechanism 53, and drives the game sphere launch mechanism 53 based on the specification of a predetermined launch operation to the launch handle 54.

  The sound light control device 82 controls driving of the light emitting unit 63 and the speaker unit 64 provided on the front door frame 14 based on various commands input from the main control device 81, and controls the display control device 111. is there. The display control device 111 executes display control of the symbol display device 41 based on the command input from the sound light control device 82.

<Electrical Configuration for Performing Various Lotteries in MPU 102>
Next, an electrical configuration for performing various lottery in the MPU 102 will be described with reference to FIG.

  The MPU 102 uses a variety of counter information to set a jackpot occurrence lottery, setting of display of the main display unit 43, setting of symbol display of the symbol display device 41, setting of display of the symbol display unit 44, etc. Specifically, as shown in FIG. 7, when the jackpot random number counter C1 used for lottery of jackpot occurrence, the jackpot type counter C2 used when determining the jackpot type, and the symbol display device 41 deviates out And the first initial value counter CN1 used to set the initial value of the big hit random number counter C1, and the second initial value counter CN2 used to set the initial value of the big hit type counter C2 , And a variation type counter CS that determines the display continuation time in the main display unit 43 and the symbol display device 41. It is set to. Furthermore, the electric combination random number counter C4 used for lottery of whether or not to set the electric combination 34a of the lower operation opening 34 to the electric combination open state, and the third initial value counter used to set the initialization value of the electric combination random number counter C4. It is assumed that CN3 is used. The counters C1 to C3, CN1, CN2, CS, C4, and CN3 are provided in the lottery counter area 104a of the RWM 104.

  Each of the counters C1 to C3, CN1, CN2, CS, C4 and CN3 is a loop counter in which 1 is added to the previous value each time it is updated, and reaches a maximum value and returns to 0. Each counter is updated at short intervals. Information corresponding to the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 is a hold storage provided in the RWM 104 as acquired information storage means when a prize winning on the upper actuation port 33 or the lower actuation port 34 occurs. It is stored in the area 104b.

  The holding storage area 104b includes a holding area RE and an execution area AE. The reserve area RE is provided with a first reserve area RE1, a second reserve area RE2, a third reserve area RE3 and a fourth reserve area RE4, according to the winning history to the upper operation port 33 or the lower operation port 34. The numerical value information of the big hit random number counter C1, the big hit type counter C2 and the reach random number counter C3 is stored as one of the hold areas RE1 to RE4 as hold information.

  In this case, the first reserve area RE1 → the second reserve area RE1 → the second reserve area RE1 to the fourth reserve area RE4 when a plurality of winnings in the upper operation port 33 or the lower operation port 34 occur consecutively in a plurality of times. Each numerical value information is stored chronologically in the order of RE 2 → third reserve area RE 3 → fourth reserve area RE 4. By providing four reserve areas RE1 to RE4 as described above, the game ball's winning history of the upper operating opening 33 or the lower operating opening 34 is reserved and stored up to four.

  The number that can be reserved and stored is not limited to four and is arbitrary, and may be other plural such as two, three, five or more, or may be singular.

  The execution area AE is an area for moving each value stored in the first holding area RE1 of the holding area RE when the variable display of the main display unit 43 is started. Based on the various numerical value information stored in the execution area AE, the determination of success or failure is performed.

  The respective counters will be described in detail.

  For example, the jackpot random number counter C1 is sequentially incremented by 1 within the range of 0 to 599, and returns to 0 after reaching the maximum value. When the big hit random number counter C1 makes one revolution, the value of the first initial value counter CN1 at that time is read as the initial value of the big hit random number counter C1. The first initial value counter CN1 is a loop counter similar to the large hit random number counter C1 (value = 0 to 599). The jackpot random number counter C1 is periodically updated, and is stored in the hold storage area 104b at a timing when the gaming ball has won the upper operating opening 33 or the lower operating opening 34.

  The value of the random number to be the jackpot win is stored as a yes / no table in the yes / no table storage area as the yes / no information group storage unit in the ROM 103. As the pass / fail table, a pass / fail table for the low probability mode and a pass / fail table for the high probability mode are set. That is, in the pachinko machine 10, the low probability mode and the high probability mode are set as the lottery mode in the hit / fall lottery means.

  Under the gaming state where the low probability mode hit / fail table is referred to at the time of the lottery, the number of random numbers to be a big hit is two. On the other hand, under the gaming state where the high-probability mode hit / fail table is referred to at the time of the lottery, the number of random numbers to be a big hit is twenty. If the winning probability in the high probability mode is higher than that in the low probability mode, the number of random numbers to be won is arbitrary.

  The jackpot type counter C2 is different in numerical range from the jackpot random number counter C1, and the numerical range is set narrower than the jackpot random number counter C1. Specifically, 1 is added sequentially in the range of 0 to 29, and after reaching the maximum value, it returns to 0. Further, when the jackpot type counter C2 makes one revolution, the value of the second initial value counter CN2 at that time is read as the initial value of the jackpot type counter C2. The second initial value counter CN2 is a loop counter similar to the jackpot type counter C2 (value = 0 to 29). The jackpot type counter C2 is periodically updated, and is stored in the hold storage area 104b at a timing when the gaming ball has won in the upper operation port 33 or the lower operation port 34.

  In the pachinko machine 10, a plurality of jackpot results are set. Specifically, (1) a mode of opening / closing control of the variable winning device 32 in the opening / closing execution mode, (2) a lottery mode in the lottery means after completion of the opening / closing execution mode, (3) a lower operation opening after the opening / closing execution mode ends A plurality of jackpot results are set by making a difference in the three conditions of the support mode in the 34 motorized parts 34a.

  As an aspect of the opening and closing control of the variable winning device 32 in the opening and closing execution mode, the occurrence frequency of winnings on the variable winning device 32 between the start and the end of the opening and closing execution mode is relatively high and low A frequency winning mode and a low frequency winning mode are set. Specifically, in any of the high-frequency winning mode and the low-frequency winning mode, a predetermined number of round games are executed with an upper limit.

  Here, the round game is continued until either a predetermined upper limit continuation time elapses or a predetermined upper limit number of gaming balls wins the large winning opening 32a. It is a game to play. Further, the number of round games in the opening / closing execution mode triggered by the jackpot result is the same as the fixed round number regardless of the type of jackpot result triggered by the transition. Specifically, the upper limit number of round games is set to 15 rounds regardless of which jackpot result.

  Further, in the pachinko machine 10, a plurality of types of opening modes of the variable winning device 32 are set such that the opening continuation time from the opening of the big winning opening 32a to the closing is different. Specifically, a long-time mode in which the opening continuation time is set to 29 sec, which is a long time, and a short-time mode in which the opening continuation time is set to 0.6 sec, which is a short time shorter than the long time, are set. It is done.

  In the pachinko machine 10, in a situation where the release handle 54 is operated by the player, the game ball emission mechanism 53 is drive-controlled so that one game ball is emitted toward the game area in 0.6 sec. . In addition, the upper limit number of end conditions of the round game is set to nine. Then, in the long time mode among the open modes, the open continuation time of a time longer than the product of the firing cycle of the game balls and one round game is set. On the other hand, in the short time mode, the opening duration time of the time shorter than the product of the game ball firing cycle and one round game, more specifically, the time shorter than the game ball firing cycle is set. Therefore, when one open of the variable winning device 32 is performed in a long time mode, it is expected that winnings corresponding to the upper limit number in one round game occur to the large winning opening 32a. When the variable winning device 32 is opened once in a short time mode, it is expected that the winning of the large winning opening 32a will not occur, or even if the winning occurs, it will be about one.

  In the high-frequency winning mode, opening of the special winning opening 32a in a long time mode is performed once in each round game. On the other hand, in the low frequency winning mode, opening of the special winning opening 32a in a short time mode is performed once in each round game.

  The number of opening and closing of the special winning opening 32a in the high frequency winning mode and the low frequency winning mode, the number of round games, the opening duration time for one opening and the upper limit number in one round game, the high frequency winning mode If the frequency of occurrence of winnings on the variable winning device 32 between the start and end of the opening and closing execution mode is higher than that in the low frequency winning mode, it is not limited to the above values and is arbitrary It is.

  As a support mode in the motorized jack 34a of the lower operation opening 34, when compared in the situation where the firing of the gaming ball is continued in the same manner with respect to the game area, the motorized prize 34a of the lower operation opening 34 is High-frequency support mode (high-frequency support state or high-frequency guide state) and low-frequency support mode (low-frequency support state or low-frequency guide state) so that the frequency of opening state per unit time becomes relatively high and low. And is set.

  Specifically, in the low-frequency support mode and the high-frequency support mode, the probability of being in the electronic combination open state winning in the electric combination opening lottery using the electronic combination random number counter C4 is the same (for example, 4/5 for both). However, in the high frequency support mode, the number of times the motorized role 34a is released when the electronic component is released is set more frequently than in the low frequency support mode, and one more open time is set. Is set long. In this case, in the high frequency support mode, when the electric work open state is elected and the open state of the motorized accessory 34a occurs a plurality of times, closing from the end of one open state to the start of the next open state The time is set shorter than one open time. Furthermore, the high frequency support mode has a shorter time than the low frequency support mode as a securing time that is minimally secured after the one electric combination opening lottery is performed and the next electric combination opening lottery is performed. Is set to be selected.

  As described above, in the high frequency support mode, the probability that the lower operating port 34 will be hit is higher than in the low frequency support mode. In other words, in the low frequency support mode, the probability of winning in the upper operation port 33 is higher than in the lower operation port 34, but in the high frequency support mode, the lower operation port 34 to the lower operation port 34. The probability of winning will increase. Then, when the lower operation opening 34 has a winning, a predetermined number of game balls are paid out, so in the high-frequency support mode, the player plays a game while not reducing his ball much be able to.

  The configuration for increasing the frequency with which the high-frequency support mode is to be in the open state per unit time than in the low-frequency support mode is not limited to the above-described one. It is also possible to increase the probability of being in the electronic combination open state winning state in. In addition, a securing time (for example, based on the winning on the through gate 35) is secured on the occasion where the next electric combination opening lottery is performed after the one electric combination opening lottery is performed (for example In the configuration where multiple types of variable display to be executed are prepared, the high frequency support mode is set so that the short securing time is easier to be selected or the average securing time is shorter than the low frequency support mode. It may be done. Furthermore, the number of times of opening is increased, the opening time is extended, and the securing time secured upon the next electric combination opening lottery being performed after the one electric combination opening lottery is performed (i.e., shorter) And one of the variable display time for the bonus item display section 44), the average time of the securing time is shortened, and the winning probability is increased, the condition of any one or any combination is applied. This may enhance the advantage of the frequent support mode over the low frequency support mode.

  The distribution destination of the game result for the jackpot type counter C2 is stored as a distribution table in the distribution table storage area as the distribution information group storage unit in the ROM 103. Then, as the distribution destination, the low probability jackpot result, the low winning high probability jackpot result, and the most advantageous jackpot result are set.

  The low probability jackpot result is a jackpot result in which the opening / closing execution mode becomes the high frequency winning mode, and after the opening / closing execution mode ends, the pass / fail lottery mode becomes the low probability mode and the support mode becomes the high frequency support mode. However, in the high-frequency support mode, the transition to the low-frequency support mode is made when the number of games has reached the end reference frequency (specifically, 100 times) after the transition.

  In the low winning high probability big hit result, the opening and closing execution mode becomes the low frequency winning mode, and after the opening and closing execution mode ends, the success or failure lottery mode becomes the high probability mode and the support mode becomes the high frequency support mode. is there. The high probability mode and the high frequency support mode continue until the lottery result in the success or failure lottery becomes the jackpot state winning, and shifts to the jackpot state by it.

  The most advantageous jackpot result is a jackpot result in which the opening / closing execution mode becomes the high frequency winning mode, and after the opening / closing execution mode ends, the pass / fail lottery mode becomes the high probability mode and the support mode becomes the high frequency support mode. The high probability mode and the high frequency support mode continue until the lottery result in the success or failure lottery becomes the jackpot state winning, and shifts to the jackpot state by it.

  Note that the normal gaming state is not the opening / closing execution mode, but the winning lottery mode is the low probability mode and the support mode is the low frequency support mode, in relation to the above gaming states. Further, as a game result, a configuration may be made in which the low winning high probability big hit result is not set.

  In the sorting table, among the values of the big hit type counter C2 of "0 to 29", "0 to 9" corresponds to the low probability big hit result, and "10 to 14" corresponds to the low winning high certain jackpot result “15-29” corresponds to the most advantageous jackpot result.

  In addition, as one kind of high probability big hit result, opening and closing execution mode becomes low frequency winning mode, furthermore, after completion of opening and closing execution mode, success and failure lottery mode becomes high probability mode, support mode is maintained in the mode until then Inappropriate low winning high probability jackpot results may be included. In this case, the jackpot result is further diversified.

  Furthermore, as one kind of out result in the success or failure lottery, while transitioning to the opening / closing execution mode of the low frequency winning mode, the special out result that transition of the success or failure lottery mode and the support mode does not occur after the end may be included. . In the configuration in which both the above-mentioned implicit low winning high probability jackpot result and the special outlier result are set, the open / close execution mode is shifted to the low frequency win mode, and the support mode is In contrast to being maintained in the mode, the transition mode of the lottery mode is different, for example, one of the implicit low winning high probability jackpot result or the special off result in the normal gaming state When it occurs, it is possible to make the player predict which result it actually corresponds to.

  The reach random number counter C3 is different in numerical range from the big hit random number counter C1 and the big hit type counter C2, and the numeric range is set narrower than the big hit random number counter C1 and wider than the big hit type counter C2. Specifically, the values are sequentially added one by one within the range of 0 to 238, and return to 0 after reaching the maximum value. The reach random number counter C3 is periodically updated, and is stored in the hold storage area 104b at the timing when the gaming ball is won in the upper operation port 33 or the lower operation port 34.

  Here, reach display is set in the present pachinko machine 10 as a type of display effect in the symbol display device 41. The reach display is provided with the symbol display device 41 capable of performing variable display of symbols, and the stop display result after the variable display is specially displayed in the game round where the open / close execution mode of the variable winning device 32 is the high frequency winning mode In the gaming machine as a result, the player is made to think that the variable display state is likely to be the special display result at a stage before the stop display result is derived and displayed after the variable display of the symbols in the symbol display device 41 is started. It says the display state for.

  In the reach display, a combination of jackpot symbols corresponding to the occurrence of the high-frequency winning mode is made by stopping and displaying the symbols for some of the plurality of symbol rows displayed on the display surface G of the symbol display device 41. A combination of reach symbols that may be established is displayed, and in that state, a display state in which the variation display of the symbols is performed in the remaining symbol rows is included. Further, while displaying combinations of reach symbols as described above, while performing variable display of symbols in the remaining symbol rows, and performing reach effects by displaying a predetermined character or the like as a moving image in the background image, or Also, it is possible to perform reach effect by displaying a predetermined character or the like as a moving image over substantially the entire display surface after reducing or non-displaying a combination of reach symbols.

  The reach display is executed regardless of the value of the reach random number counter C3 in the gaming round to shift to the open / close execution mode which is the high-frequency winning mode. In addition, in game times which are not shifted to the opening / closing execution mode, the reach random number counter C3 acquired at a predetermined timing is referred to in response to the occurrence of reach display with reference to the reach table stored in the reach table storage area of the ROM 103 Will be executed if

  The variation type counter CS is different in numerical range from the big hit random number counter C1 and the big hit type counter C2, and the numeric range is set narrower than the big hit random number counter C1 and wider than the big hit type counter C2. Specifically, 1 is added sequentially in the range of 0 to 198, and after reaching the maximum value, it returns to 0. The fluctuation type counter CS is used when the MPU 102 determines the fluctuation display time on the main display unit 43 and the fluctuation display time of the symbol on the symbol display device 41. The fluctuation type counter CS is updated in each of main processing and timer interrupt processing to be described later, and the fluctuation type counter is determined at the start of fluctuation display on the main display unit 43 and at the time of fluctuation pattern determination by the symbol display device 41. The value of CS is obtained. In addition, when determining the fluctuation display time, the fluctuation display time table stored in advance in the fluctuation display time table storage area of the ROM 103 is referred to.

  The random number counter C4 has a different numerical range from the big hit random number counter C1 and the big hit type counter C2, and the numeric range is set narrower than the big hit random number counter C1 and wider than the big hit type counter C2. . Specifically, 1 is added sequentially in the range of 0 to 250, and after reaching the maximum value, it returns to 0. In addition, when the electronic combination random number counter C4 makes one revolution, the value of the third initial value counter CN3 at that time is read as the initial value of the electronic combination random number counter C4. The third initial value counter CN3 is a loop counter similar to the random number counter C4 (value = 0 to 250). The random number counter C4 is periodically updated, and is stored in the commercial pattern holding area 104c provided in the RWM 104 at the timing when the game ball wins the through gate 35. Then, at a predetermined timing, a lottery is performed to determine whether or not the motorized combination 34a is to be controlled to the open state based on the value of the stored electronic combination random number counter C4.

<Various processing executed by MPU 102>
Next, each process performed in order to advance a game in MPU102 is demonstrated. The processing of the MPU 102 can be roughly divided into main processing activated upon power on and timer interrupt processing activated periodically.

<Main processing>
First, main processing will be described with reference to the flowchart of FIG.

  First, in step S101, power on wait processing is performed. In the power-on wait process, for example, the process waits until 1 sec elapses after the main process is started, without progressing to the next process. In the following step S102, access to the RWM 104 is permitted, and in step S103, the internal function register of the MPU 102 is set.

  Thereafter, in step S104, it is determined whether or not the RWM erase switch provided in the power supply and emission control device 98 is manually operated, and in the subsequent step S105, whether or not "1" is set in the power failure flag of RWM 104 Determine if In step S106, a checksum calculation process is performed to calculate a checksum. In the subsequent step S107, it is determined whether the checksum matches the checksum stored at the time of power shutdown, that is, the validity of stored data. judge.

  In the case of the pachinko machine 10, for example, when the RWM data is initialized at the time of power on, such as at the start of business operation of the game hall, the power is turned on while pressing the RWM erase switch. Therefore, if the RWM erase switch is pressed, the process proceeds to step S108. In addition, when the occurrence information of the power-off is not set, or when the abnormality of the data stored and held is confirmed by the checksum, the process similarly shifts to the process of step S108. In step S108, the RWM 104 is cleared as initialization of the RWM 104. Thereafter, the process proceeds to step S109.

  On the other hand, when the RWM erase switch is not pressed, the process in step S108 is not performed under the condition that the power failure flag is set to “1” and the checksum is normal. Go to In step S109, power on setting processing is performed. In the power on setting process, a predetermined area of the RWM 104 such as initialization of a power failure flag is set to an initial value, and a command corresponding to the current gaming state is transmitted to the sound light control device 82 to recognize the current gaming state. Do. Further, a payout initialization command indicating that the initialization of RWM of the payout control device 97 should be performed is transmitted to the payout control device 97. Further, in order to permit the generation of timer interrupt processing, the interrupt permission is set.

  Thereafter, the process proceeds to the remaining process of step S110 to step S115. That is, although the MPU 102 is configured to periodically execute the timer interrupt process, a remaining time is generated between one timer interrupt process and the next timer interrupt process. Although this remaining time fluctuates according to the processing completion time of each timer interrupt process, the remaining process of step S110 to step S115 is repeatedly executed using such irregular time. In this regard, it can be said that the remaining processing in step S110 to step S115 is nonperiodic processing that is performed nonperiodically.

  In the remaining process, first, in step S110, in order to inhibit the generation of the timer interrupt process, the interrupt disable setting is performed. Thereafter, in step S111, the first initial value updating process for updating the first initial value counter CN1 is executed, and in step S112, the second initial value updating process for updating the second initial value counter CN2 is executed. Then, in step S113, the third initial value updating process of updating the third initial value counter CN3 is executed, and in step S114, the updating process of the variation type counter CS is executed.

  In these update processes, the present numerical value information is read out from the corresponding counter of the RWM 104, and a process of adding one to the read out numerical value information is executed, and then a process of overwriting the read source counter is executed. In this case, when the counter value reaches the maximum value, it is cleared to "0".

  After that, in step S115, interrupt permission setting is performed to switch from the state where the generation of the timer interrupt processing is prohibited to the state where it is permitted. If the process of step S115 is performed, it will return to step S110 and will repeat the process of step S110-step S115.

<Timer interrupt processing>
Next, timer interrupt processing will be described with reference to the flowchart of FIG.

  Here, a hardware configuration for periodically executing timer interrupt processing in the MPU 102 will be described. The main control board 101 is provided with a clock circuit as pulse signal output means for outputting a pulse signal at a predetermined cycle, and a divider circuit so as to be present in the middle of the signal path between the clock circuit and the MPU 102. Is provided.

  The divider circuit functions as frequency changing means for changing the cycle of the pulse signal from the clock circuit, and is configured to output a pulse signal for specifying the start timing of the timer interrupt processing by the MPU 102. That is, pulse signals are supplied from the divider circuit to the MPU 102 at an interval of 4 msec which is a specific cycle. The MPU 102 executes processing to confirm the occurrence of a specific signal form such as rising or falling of the pulse signal, and starts and executes timer interrupt processing under at least one condition that the occurrence of the specific signal form is confirmed. Do.

  In this case, when the generation of the specific signal form is confirmed in a state where activation of the timer interrupt processing is prohibited, the timer is changed to a state where the interrupt is permitted from the state where the interrupt is prohibited. Interrupt processing is started. That is, depending on the execution status of the process in the MPU 102, the timer interrupt process may be started 4.1 msec after the previous timer interrupt process is started. If such an event occurs, the next process may be performed. The timer interrupt process may be started 3.9 msec after the previous timer interrupt process is started.

  The case where the timer interrupt process is not activated even though 4 msec has elapsed is that interrupt prohibition is set in step S110 and 4 msec has elapsed while the remaining process is being executed. . Therefore, the start timing of the timer interrupt process fluctuates depending on the execution status of the remaining process.

  However, since the output of the pulse signal from the divider circuit is performed at a specific cycle such as 4 msec regardless of the progress of the process in the MPU 102, basically the timer interrupt process is started at a specific cycle. Furthermore, even if the processing configuration of the MPU 102 is started after the timer interrupt processing at a predetermined timing has passed a period exceeding a specific period since the previous timer interrupt processing was started, the timing following the predetermined timing is The timer interrupt process in is absorbed by an amount exceeding that specific period, and the timer interrupt process at the next timing is set to be activated at the timing at which the input of the pulse signal is confirmed.

  The mode in which the timer interrupt process is periodically started is not limited to the above mode, and is basically started at a predetermined cycle such as 4 msec. Even if the new timer interrupt process is started after the time equivalent to the predetermined cycle has elapsed, because the timing at which the time corresponding to the cycle has elapsed is in the middle of the remaining process, the next timer The interrupt process may not be started at the timing before the lapse of the time corresponding to the predetermined cycle after the start of the new timer interrupt process. That is, the timer interrupt process is basically started at a predetermined cycle, and may be started at an interval of time exceeding the predetermined cycle in relation to the remaining process, while the time is below the predetermined cycle. The configuration may not be started at the interval. Even in this case, the start interval of the timer interrupt process may vary in relation to the remaining process.

  Now, in the timer interrupt process, first, in step S201, a power failure information storage process is executed. In the power failure information storage process, whether or not the power failure signal corresponding to the occurrence of the power interruption is received from the power interruption monitoring board 105 through the input / output port provided in the MPU 102 is monitored, and the occurrence of the power interruption is identified. Execute time processing.

  In the subsequent step S202, a lottery random number update process is executed. In the random number updating process for drawing, the big hit random number counter C1, the big hit type counter C2, the reach random number counter C3, and the electric part random number counter C4 are updated. Specifically, the present numerical value information is sequentially read out from the big hit random number counter C1, the big hit type counter C2, the reach random number counter C3 and the electric part random number counter C4, and the read out numerical information is added one by one. Execute processing to overwrite the counter of reading source.

  In this case, for the counter whose numerical value information has reached the maximum value, the numerical value information is cleared to "0" which is the minimum value. Also, for the big hit random number counter C1, the big hit type counter C2 and the electric part random number counter C4, when the updating of the numerical information makes a round, the information of the initial value is read from the corresponding initial value counters CN1 to CN3 and read Overwrite the information of the initial value as the initial value of the new cycle.

  Here, the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 will be described later in a state where the game is proceeding normally (specifically, a state where a negative determination is made in step S206 described later). The configuration is such that it is executed once for one execution of the special drawing special power control process of step S214. In the special figure special power control process, the process of monitoring the winning of the operation opening 33, 34 is executed, and when the winning of the operation opening 33, 34 occurs, the big hit random number counter C1, the big hit type A process of acquiring numerical information from the counter C2 and the reach random number counter C3 is executed. Then, based on the acquired numerical value information, a process of determining whether or not a big hit has been made, a process of determining whether a big hit has been made, or a process of determining whether or not a reach has been made is performed.

  In other words, each of the big hit random number counter C1, the big hit type counter C2 and the reach random number counter C3 is configured such that the process of updating the numerical information is performed once for one occasion that makes it possible to acquire those numerical information. ing. Then, as described above, each of the big hit random number counter C1, the big hit type counter C2 and the reach random number counter C3 is assumed that the update round is completed once when all target numerical information is set once each. It is judged. Therefore, when the jackpot is generated and the jackpot is generated with the probability set at the design stage of the pachinko machine 10, the ratio set at the design stage of the pachinko machine 10 is one of the respective jackpot results It is distributed. When the jackpot is not won, reach display occurs with the probability set at the design stage of the pachinko machine 10.

  In addition, in a state where the game is progressing normally (specifically, in a state where a negative determination is made in step S206 described later), the electronic random number counter C4 performs the routine diagram general control processing of step S215 described later. It is configured to be executed once for one execution. In the general-purpose-general-power control processing, processing for monitoring winning on the through gate 35 is executed, and when winning on the through gate 35 occurs, numerical information is acquired from the electronic random number counter C4. Processing is performed. Then, based on the acquired numerical value information, determination processing as to whether or not to set the motorized prize 34a in the open state is executed.

  That is, the electronic part random number counter C4 has a configuration in which the process of updating the numerical information is performed once with respect to one opportunity for obtaining the numerical information. Then, as described above, it is determined that the updating round is completed once when all the numerical value information to be targets are set once each, as described above. Therefore, the open winning of the motorized jack 34 a occurs with the probability set at the design stage of the pachinko machine 10.

  Thereafter, in step S203, various initial value update processing is executed. In the various initial value update processing, processing similar to the above-mentioned step S111 to step S113 is executed. In step S204, as in the case of step S114, the process of updating the variation type counter CS is executed.

  In the following step S205, a game stop determination process is executed. In the game stop determination process, the detection result of the magnet detection sensor 109 is read through the input / output port provided in the MPU 102, and it is determined whether the detection result corresponds to the occurrence of the fraud. Further, it is determined whether or not the fraud is detected in step S211 in the previous timer interrupt process. If affirmative determination is made in any of these determination processes, it is specified that the progress of the game should be stopped, and if both determination processes make a negative determination, the game proceeds To identify that it is not a situation to stop.

  Thereafter, in step S206, it is determined whether or not the progress of the game is stopped, and the processes after step S207 are executed on the condition that the progress of the game is not stopped.

  In step S207, port output processing is performed. In the port output process, when setting of output information is performed in the previous timer interrupt process, a process for performing an output corresponding to the output information to the various drive units 107 and 108 is executed. For example, when the information to switch the special winning opening 32a to the open state is set, the output of the drive signal to the variable prize drive unit 107 is started, and the information to switch to the closed state is set. The output of the drive signal is stopped. Further, when the information to switch the motorized part 34a of the lower operation opening 34 to the open state is set, the output of the drive signal to the item drive unit 108 is started, and the information to be switched to the closed state is set. If it does, the output of the drive signal is stopped.

  In the following step S208, a reading process is performed. In the reading process, reading of signals other than the power failure signal and the winning signal is executed, and the read information is stored for use in future processing.

  In the subsequent step S209, a winning detection process is executed. In the winning detection process, the signals received from each of the winning detection sensors 106a to 106h are read, and the general winning opening 31, the special winning opening 32a, the upper operating opening 33, the lower operating opening 34 and the through gate 35 are selected. Execute processing to identify presence or absence.

  In the subsequent step S210, a timer update process for collectively updating numerical information of a plurality of types of timer counters provided in the RWM 104 is executed. In this case, the timer counter is stored in which the stored numerical information is subtracted and updated, but both the update of the subtraction type timer counter and the update of the addition type timer counter are collectively performed. It is good also as composition.

  In the subsequent step S211, a fraud detection process is performed to monitor whether or not a predetermined event set as a fraud monitoring target has occurred. In the fraud detection process, the occurrence of a plurality of types of events is monitored, and a predetermined event is occurring (for example, a vibration detection sensor (not shown) is detecting vibration or a radio wave detection sensor (not shown) By confirming that it is detected, setting for stopping the game is performed in the above-mentioned step S205 in the next timer interrupt processing, and an affirmative determination is made in step S206.

  In the following step S212, a launch control process is performed to control the launch of the gaming ball. In the situation where the firing operation is continued to the firing handle 54, as described above, one gaming ball is fired in 0.6 seconds which is a predetermined firing cycle.

  In the subsequent step S213, as input state monitoring processing, confirmation of disconnection of each of the winning detection sensors 106a to 106h and confirmation of opening of the gaming machine main body 12 and the front door frame 14 based on the information read in the reading processing of step S208. Do.

  In the following step S214, special figure electric power control processing for executing execution control of game times and execution control of the open / close execution mode is executed. The contents of the special figure special power control process will be described later.

  In the following step S215, the general-purpose power control process is executed. When the winning gate on the through gate 35 has been awarded, the routine control routine executes processing for acquiring the hold information on the general view side, and the hold information on the general view side is stored. Then, the release determination is performed on the hold information, and the release determination is used as a trigger to execute processing for producing effects for the common drawing. Further, based on the result of the open determination, processing of opening and closing the motorized accessory 34 a of the lower operation port 34 is executed.

  In the subsequent step S216, based on the processing results of the immediately preceding step S214 and step S215, setting of output information for reflecting the increase / decrease number of the hold information concerning the main display unit 43 on the first hold light emitting unit 45 is performed. The output information for reflecting the increase / decrease number of the hold information related to the role-character display unit 44 on the second hold light-emitting unit 46 is set. Further, in step S216, based on the processing results of the immediately preceding step S214 and step S215, the output information for updating the display content of the main display unit 43 is set, and the display content of the bonus item display unit 44 is set. Set the output information for updating.

  In the following step S217, a process for demonstration display is performed to set the display content of the symbol display device 41 for standby display in a situation where neither the game times nor the open / close execution mode is executed, and in step S218 The contents of the command and signal received from the payout control device 97 are confirmed, and a payout state reception process for executing a process corresponding to the confirmation result is executed. In step S219, a payout output process for setting a winning ball command as an output target is executed.

  In the subsequent step S220, an external information setting process is performed to control the start and end of output of an external signal according to the process result of various processes executed in the current timer interrupt process. In step S221, a process for editing the test shot information is executed.

  When an affirmation judging is carried out at Step S206, or after processing of Step S207-Step S221 is performed, it progresses to Step S222. In step S222, the setting of the interrupt end declaration is performed. In the MPU 102, once the timer interrupt process is started, it is defined that the setting of the interrupt end declaration is performed as one of the conditions for starting the next timer interrupt process, and in step S222, the next timer is set. In order to enable execution of interrupt processing, the interrupt end declaration is set. In step S223, interrupt permission is set. Once the timer interrupt process is activated, the MPU 102 is set to a state of interrupt prohibition, so in step S223, interrupt permission is set to enable execution of the next timer interrupt process. Thereafter, this timer interrupt processing is ended.

<Special figure special power control process>
Next, the special figure special power control process executed in step S214 of the timer interrupt process (FIG. 9) will be described with reference to the flowchart of FIG.

  In the special figure special power control process, the process for acquiring the hold information is executed when the upper operation port 33 or the lower operation port 34 has a winning, and the hold is performed when the hold information is stored. Whether the information is accepted or not is determined, and further, a process for producing effects for the game cycle is executed in response to the determined availability. Further, based on the result of the success or failure determination, the processing to shift to the opening / closing execution mode after the presentation for the game cycle is executed, and the processing in the opening / closing execution mode and at the end of the opening / closing execution mode is executed.

  Specifically, first, in step S301, a process of acquiring pending information is executed. In the process of acquiring the hold information, it is determined whether or not a winning has occurred in the upper operating port 33 or the lower operating port 34, and if a winning has occurred, the number of holdings storage area NA in the holding storage area 104b is determined. The stored number of holdings is read out, and it is determined whether the number of holdings is less than the upper limit value ("4" in the present embodiment). If the number of reservations is less than the upper limit value, the number of reservations is incremented by 1 and each numerical information of the jackpot random number counter C1, jackpot type counter C2 and reach random number counter C3 updated in the previous step S202 is for hold It stores in the first reserve area among the reserve areas RE1 to RE4 of the area RE.

  When winning in the upper operation port 33 and the lower operation port 34 is occurring simultaneously, the process for acquiring the above-mentioned suspension information is performed multiple times within the range where the acquisition process of the suspension information is executed once. Run.

  After executing the acquisition process of pending information in step S301, the process proceeds to step S302. In step S302, a process of reading information of the special view special charge counter provided in the RWM 104 is executed. In the subsequent step S303, processing for reading out the special figure special power address table from the ROM 103 is executed. Then, in step S304, processing is performed to acquire the start address corresponding to the information of the special figure special charge counter from the special figure special charge address table.

  Here, the processing content of step S302 to step S304 will be described.

  As described above, the special view special power control process includes a process relating to an effect for game circulation and a process relating to the open / close execution mode. In this case, as a process relating to the effects for the game run, the special figure variation start process (step S306), which is a process for starting the effect for the game run, and the process for advancing the effect for the game run A special figure changing process (step S307) and a special figure determining process (step S308), which is a process for ending the effects for game circulation, are set.

  Also, as the processing related to the opening / closing execution mode, the special power start processing (step S309) which is processing for controlling the opening of the opening / closing execution mode, and the special electric power processing for controlling the open state of the special winning opening 32a. Processing during opening (step S310) and processing during special power closing (step S311) which is processing for controlling the closing state of the big winning opening 32a, ending in the opening / closing execution mode, and gaming state at the end of the opening / closing execution mode And a special power termination process (step S312), which is a process for controlling the transition of the image.

  In such a processing configuration, the special figure special charge counter is a counter for the MPU 102 to grasp which of the plurality of types of processing should be executed, and the special figure special charge address table A start address of a program for executing the plurality of types of processing is set corresponding to the numerical information of the special charge counter.

  In this case, the start address SA0 is a start address of a program for executing the special figure change start process (step S306), and the start address SA1 is a program for performing the special figure change in process (step S307). The start address SA2 is a start address of a program for executing the special figure determination process (step S308). The start address SA3 is a program for performing a special power start process (step S309). The start address SA4 is a start address of a program for executing the special power release process (step S310). The start address SA5 is a program for performing the special power close process (step S311). Start address, start address SA6 A start address of a program for executing (step S312).

  The special figure special power counter performs special figure special power control in the next processing cycle when the condition for updating the numerical value information is satisfied when the process corresponding to the currently stored numerical information is finished. One is added, one is subtracted, or "0" is cleared (initialized) corresponding to the process executed in the process. Therefore, in the special figure special power control process in each processing cycle, the process according to the numerical information set in the special figure special power counter may be executed.

  According to the above configuration, it is possible to grasp which processing is to be executed as the special figure special power control by the MPU 102 without checking the presence or absence of various flags. For example, although the effect for game circulation is started when the effect for other game circulation is not executed and it is not in the open / close execution mode, when trying to judge each state by the presence or absence of the flag, the game circulation Before starting the game circulation effect in the processing related to the production of the game, check whether the flag indicating that the game circulation effect is being executed is set or not, and the opening / closing execution mode is being executed There is a need to check whether the flag indicating that is is set or not. In addition, during execution of the game circulation effect, confirmation is made as to whether or not a flag indicating that the game circulation effect is being executed is set, and a flag indicating that the final display is in effect. There is a need to check whether the

  In addition, the opening and closing execution mode is started when the effects for the game are ended and the other opening and closing execution modes are not executed, but when trying to judge each state according to the presence or absence of the flag, it relates to the opening and closing execution mode In processing, before starting the opening and closing execution mode, it is confirmed whether or not the flag indicating that the effect for the game cycle is finished is set, and the flag indicating that the opening and closing execution mode is under execution is set It is necessary to confirm whether or not it has been done, and if it is in the process of opening, it is also necessary to confirm whether or not the flag indicating that it is in the process of opening is set. Also, after the opening, it is checked whether the flag indicating that the open / close execution mode is being executed is set or not, and the flag indicating that the special winning opening 32a is open is set or not It will be necessary to Furthermore, when in the process of ending, it is necessary to check whether a flag indicating that the process is in progress is set.

  On the other hand, if a special drawing special charge counter is used, it is not necessary to prepare various flags, and furthermore, the information at the time of confirming the execution timing of each process is also collected. Thus, the processing can be simplified.

  After the process of step S304 is performed, in step S305, a process of jumping to the process indicated by the start address acquired in step S304 is performed. Specifically, when the acquired start address is SA0, the process jumps to the special map change start process of step S306.

  In the special figure fluctuation start process, on the condition that the suspension information is stored on hold, it is determined whether or not the suspension information corresponds to the big hit in the case of supporting the big hit or the win determination process. Executes a distribution determination process to determine which jackpot result the hold information corresponds to. At the time of the propriety determination processing, it is determined whether the numerical information acquired from the jackpot random number counter C1 in the hold information is the numerical information corresponding to the jackpot winning. Further, in the distribution determination process, it is determined whether the numerical information acquired from the jackpot type counter C2 in the hold information corresponds to any of the jackpot result classifications.

  In addition to the success / failure determination process and the distribution determination process, when the suspension information does not correspond to the big hit, the reach determination process is performed to determine whether the suspension information corresponds to the reach occurrence. Using the numerical information of the fluctuation type counter CS at that time, the processing of selecting the duration to select the duration of the game is executed. In the reach determination process, it is determined whether the numerical information acquired from the reach random number counter C3 in the hold information corresponds to the numerical information of the reach occurrence.

  When the information of the duration is selected, the variation command including the information of the duration and the type command including the information of the game result are transmitted to the sound light control device 82 and the variation of the pattern in the main display 43 Start the display. As a result, one game cycle is started, and effects of the game cycle are started on the main display unit 43 and the symbol display device 41.

  By the way, when the effect for the game circulation is started in this way, the numerical information of the special figure special power counter is incremented by 1, and the numerical information of the counter is selected from those corresponding to the special figure fluctuation start process. Update to the one corresponding to the processing during fluctuation.

  If the acquired start address is SA1, the process jumps to the special figure variation processing of step S307. In the special figure changing process, a process of determining whether or not it is in the continuation time of the game and is the timing before the finalized display is executed, and if it is the finalized display, the display mode of the design in the main display 43 Execute the process to change regularly.

  By the way, this special view change is not performed after waiting for the special display change processing until the final display timing is reached, and after the process for regularly changing the above-mentioned regular display is not performed. End the process. Therefore, after the special effects for the game are started, the special figure variation in progress process is activated every time the special figure electric power control process is activated, until the timing for finalizing the display. In addition, when it is time to display fixedly, by adding 1 to the numeric information of the special chart special power counter, it corresponds to the special chart finalization process from the one corresponding to the special chart fluctuation process of the numerical information of the counter. Update to what you

  If the acquired start address is SA2, the process jumps to the processing during special image determination in step S308. In the special figure finalization process, the final stop command is transmitted to the sound light control device 82 in order to cause the final display of the stop result of the current game run to be displayed on the symbol display device 41, and the display of the pattern on the main display 43 The mode is a display mode corresponding to the lottery result of the current game run. Further, in the processing during special figure determination, it is determined whether or not the period during the definite display has elapsed, and when the period has elapsed, it is determined whether or not transition to the open / close execution mode occurs. When transition to the open / close execution mode occurs, processing for the mode transition is executed.

  By the way, instead of waiting in the processing during the special drawing determination until the period during the definite display elapses, the processing during the special drawing determination is ended when the period has not elapsed. Therefore, after the definite display is started, the special figure determination processing is activated every time the special figure electric power control processing is activated until the period during the definite display elapses. In addition, if the transition to the open / close execution mode does not occur when the fixed display period has elapsed, the numeric information of the special figure special power counter is initialized (that is, "0" is cleared), and the transition to the open / close execution mode is performed. In a situation where occurs, the numerical information of the special figure special power counter is incremented by 1, and the numerical information of the counter is updated from the one corresponding to the processing during the special figure determination to the one corresponding to the special power start processing.

  If the acquired start address is SA3, the process jumps to the special power start process of step S309. In the special power start process, an opening command indicating that the open / close execution mode is started is transmitted to the sound light control device 82. Also, in the special power start process, it is determined whether or not the opening period of the open / close execution mode has elapsed. If the opening period has not elapsed, the special power start process is terminated instead of waiting in the special power start process. Therefore, after the opening effect in the open / close execution mode is started, the special power start process is activated every time the special electric power control process is activated until the opening period elapses. Also, when the opening period has elapsed, the numerical information of the special electric power special counter is incremented by 1, and the numerical information of the counter is updated from the one corresponding to the special electric power start process to the one corresponding to the special electric power open process. .

  If the acquired start address is SA4, the process jumps to the processing during the power-on release in step S310. In the special power open process, it is determined whether a round game of 1 is started and whether or not an end condition of the round game is established. If the termination condition is not satisfied, the process does not stand by in the process of opening the TPC, but after executing the process for monitoring the establishment of the termination condition, the process of the TPC being opened is ended. When the above termination condition is satisfied, the numerical information of the special electric power special counter is added by 1 to change the numerical information of the counter from the one corresponding to the special electric power open process to the one corresponding to the special electric power closed process. Update.

  If the acquired start address is SA5, the processing jumps to the processing during the special power closing of step S311. In the special power closed process, a process to end one round game is executed. In addition, in an interval period between round games, it is determined whether an interval period has elapsed. If the interval period has not elapsed, the process is terminated instead of waiting in the process of closing the special power supply, but ending the process of closing the special electric charge. Therefore, when the interval period is started, the special electric power closing process is activated every time the special electric power special control process is activated until the period has elapsed. In addition, when the interval period has elapsed, the numerical information of the special power special counter is decremented by 1, and the numerical information of the counter is updated from the one corresponding to the special electric power closing process to the one corresponding to the special electric power open process. Do.

  On the other hand, after the processing to end one round game is executed in the special electric power closing processing for the last round game, the numerical information of the special electric power special counter is added to one to process the numerical information of the counter to special electric power closing processing. Update to the one corresponding to the special power termination processing from the corresponding one.

  If the acquired start address is SA6, the process jumps to the special power termination process of step S312. In the special power termination process, an ending command indicating that the open / close execution mode is terminated is transmitted to the sound light control device 82. Further, in the special power termination process, it is determined whether the ending period of the open / close execution mode has elapsed. If the ending period has not elapsed, the special power termination process is ended instead of waiting in the special power termination process. Therefore, after the ending effect in the open / close execution mode is started, the special power termination process is activated every time the special electric power control process is activated until the ending period elapses. In addition, when the ending period has elapsed, after executing processing for setting the gaming state after the open / close execution mode (incidence lottery mode and support mode), by initializing the numerical information of the special figure special charge counter The numerical value information of the counter is updated from the one corresponding to the special power termination processing to the one corresponding to the special drawing fluctuation start processing.

<Countermeasures against the act of impersonating the acquisition of numerical information>
Here, the pachinko machine 10 illegally reads that the jackpot random number counter C1 is the predetermined numerical information, and further, based on the reading result, the numerical information of the jackpot random number counter C1 corresponds to the numerical information corresponding to the jackpot. By setting the state as if the winning of the operation ports 33 and 34 has occurred at the timing when it has become, it is assumed that an action is made to illegally generate the transition to the open / close execution mode. Hereinafter, the configuration for preventing the fraud will be described.

  Prior to the description of the configuration of the countermeasure against the fraud, how the fraud is performed will be described with reference to FIG. FIG. 11 is a block diagram for explaining an electrical configuration when the MPU 102 receives a signal from the outside of the MPU 102.

  As shown in FIG. 11, the MPU 102 is provided with an input / output port 102 a for receiving a signal from the outside of the MPU 102 and transmitting a signal to the outside of the MPU 102. The input / output port 102a is provided with a predetermined number (specifically, eight) of terminals, and the input / output port 102a is used for input according to the state of a predetermined flag provided in the register in the MPU 102. It is switched between the state and the state for output.

  In the situation where the input / output port 102a is in the state for input, the MPU 102 receives various signals from the outside of the MPU 102. The type of this signal is as described above, and a signal corresponding to the occurrence of a power failure is received from the power failure monitoring board 105, and the various winning detection sensors 106a to 106h (see FIG. 6) correspond to the winning detection results. The received signal is received, and further, a signal corresponding to the detection result of magnetism is received from the magnet detection sensor 109. Also, it receives signals other than these. The number of types of signals to be input is larger than the number of terminals provided in the input / output port 102a.

  The main control board 101 is provided with a first port driver 101a and a second port driver 101b corresponding to this, and a signal to be input is input to each port driver 101a, 101b. The structure is The number of signal types input to the first port driver 101a is equal to or less than the number of terminals of the input / output port 102a, and the number of signal types input to the second port driver 101b is also input / output. It is less than the number of terminals of the port 102a.

  In this case, the blackout monitoring board 105 is electrically connected to the first port driver 101a through the first signal path LN1, and a blackout signal from the blackout monitoring board 105 (when no blackout is detected) One of HI and LOW, which is the other of HI and LOW when a power failure is detected, is input to the first port driver 101a. Further, the magnet detection sensor 109 is electrically connected to the second port driver 101b through the second signal path LN2, and the magnet detection signal from the magnet detection sensor 109 (when magnetism is not detected) Is one of HI and LOW, and when magnetism is detected, the other is HI and LOW) is input to the second port driver 101b.

  The first port driver 101a and the second port driver 101b are electrically connected to the input / output port 102a through the third signal path LN3. In this case, in the third signal path LN3, the signal path continuing from the driver 101a for the first port and the signal path continuing from the driver 101b for the second port merge at an intermediate position, and the signal path after the joining is the input / output port It is connected to 102a.

  Further, the MPU 102 is electrically connected to the first port driver 101a through a fourth signal path LN4 different from the third signal path LN3, and a fifth signal path LN5 different from the third signal path LN3. Are electrically connected to the second port driver 101b. When a signal is output from the MPU 102 to the first port driver 101a through the fourth signal path LN4, a signal output source in which a signal to be received by the MPU 102 is connected to the first port driver 101a It becomes a signal from On the other hand, when a signal is output from the MPU 102 to the second port driver 101b through the fifth signal path LN5, a signal to be received by the MPU 102 is connected to the second port driver 101b. It becomes a signal from the output source.

  In the above configuration, when the large random number counter C1 illegally reads that the predetermined numerical information is obtained, for example, the illegal device A is electrically connected to each of the fourth signal path LN4 and the fifth signal path LN5. Enables the MPU 102 to identify whether it is receiving a signal through the first port driver 101a or receiving a signal through the second port driver 101b. . By the way, when electrically connecting the unauthorized device A existing outside the main control device 81 to the fourth signal path LN4 and the fifth signal path LN5, the substrate box 83 of the main control device 81 is incorrect. Improper connections are made through the holes formed in the or the vents formed in the substrate box 83.

  In this case, in the timer interrupt process (FIG. 9) described above, a power failure information storage process (step S201) and a game stop determination process (step S205) exist with the random number update process for lottery (step S202) interposed therebetween. When the unauthorized device A is electrically connected as described above, the signal output is performed through the fourth signal path LN4 and the signal output is performed through the fifth signal path LN5. By reading the time between them, it becomes possible to grasp the time required for the random number updating process for lottery (step S202).

In the lottery random number updating process, as described above, the process of updating the numerical information of the jackpot random number counter C1 is executed, but when updating the numerical information,
1. In the case where only one addition of numerical information is performed so that the numerical information becomes numerical information of the next order 2. Clearing to the minimum value when the result of adding 1 of the numerical information so that the numerical information becomes the next numerical information exceeds the maximum value. When the result obtained by adding 1 to the numerical information so that the numerical information becomes the numerical information in the next order becomes the initial value in the update round of the current numerical information, the initial value is newly added from the first initial value counter CN1 Case to acquire and set 1. ~ 3. There are three types of update modes.

  The processing time required for each of these update modes is different. Specifically, the above 1. <Above 2. <Above 3. The processing time increases in the order of. Therefore, the above 1. ~ 3. Depending on which is executed, the processing time required from the power failure information storage process (step S201) to the game stop determination process (step S205) also fluctuates.

  Under such circumstances, when the time taken for the random number updating process for lottery (step S202) is grasped by the unauthorized device A as described above, the process of updating the numerical information of the jackpot random number counter C1 becomes the above-mentioned 1.. ~ 3. It is possible to identify which of the two is being executed. In particular, the above 2. And 3. above. In the case of 1) above. The processing time is largely different from that in the case of It is possible to easily identify that the other is being executed.

  Above 2. In the case where it is specified that the numerical value information of the jackpot random number counter C1 is "0", which is the minimum value, is specified. Then, if the type of numerical information to be a big hit and the update cycle of the big hit random number counter C1 are grasped in advance by illegally acquiring the ROM 103 of the main control device 81, the big hit random number counter C1 can be obtained as described above. If it is possible to acquire the timing when the numerical information becomes “0”, it is indicated to the MPU 102 that the winning detection sensor of the operation opening 33, 34 has detected a winning at the timing when the numerical information of the big hit random number counter C1 becomes the numeric information corresponding to big hit. It becomes possible to make it identify. In this case, the jackpot will be unfairly generated. In addition, by electrically connecting the fraudulent device A to the signal path between the prize detection sensor of the actuation opening 33, 34 and the MPU 102, the prize detection sensor of the actuation opening 33, 34 detects a prize at the above timing. It is possible to make the MPU 102 identify.

  Hereinafter, a plurality of patterns of the configuration to be a countermeasure against the above-mentioned fraud will be described.

<First pattern>
First, the configuration of a first pattern that is a countermeasure against the above-mentioned fraudulent activity will be described.

  FIG. 12 is a flowchart showing the lottery random number updating process (step S202) in the first pattern.

  In the lottery random number updating process, first, in step S401, a jackpot random number updating process for periodically updating the numerical information of the jackpot random number counter C1 is executed. Details of the jackpot random number update process will be described later.

  In step S402, jackpot type update processing for periodically updating the numerical information of the jackpot type counter C2 is executed, and in step S403, reach random number update for periodically updating the numerical information of reach random number counter C3. The processing is executed, and in step S404, a power supply random number update processing for periodically updating the numerical information of the power supply counter random number counter C4 is executed. The details of the processing contents of steps S402 to S404 are the same as the processing contents described in step S202. Thereafter, the lottery random number update process is ended.

  Next, the jackpot random number update process will be described with reference to the flowchart of FIG.

  First, in step S501, numerical value information held in the big hit random number counter C1 is read out to the register of the MPU 102, and in step S502, 1 is added to update the read numerical information so as to be the next numerical information. Thereafter, in step S503, it is determined whether the numerical information of the result updated in step S502 exceeds the maximum value (specifically, "599") of the jackpot random number counter C1 (specifically, " It is judged whether it is 600 "or more).

  When the maximum value is not exceeded (step S503: NO), while the process for time adjustment (or delay processing) is executed in step S504, when the maximum value is exceeded (step S503: YES), In step S505, the numerical value information updated in step S502 is set to numerical value information of the minimum value, specifically, "0".

  Here, in the time adjustment process in step S504, the processing time required for updating the numerical information of the big hit random number counter C1 by one in accordance with the update order, that is, adding 1 to the numeric information of the big hit random number counter C1, is When setting the numerical information exceeding one boundary of the numerical range to the other boundary after updating the numerical information by one in the update order, that is, setting the numerical information of the jackpot random number counter C1 to "0" which is the minimum value It is a process for making the processing time of the jackpot random number updating process in the former case approach the processing time of the jackpot random number updating process in the latter case in a configuration shorter than the processing time required in the case of the former. More specifically, the processing time for the jackpot random number update process in the former case is the same as or substantially the same as the processing time for the jackpot random number update process in the latter case.

  The specific content of the time adjustment process will be described in relation to a program counter provided in the register of the MPU 102. FIG. 13B is an explanatory diagram for explaining the contents of the time adjustment process in relation to the program counter.

  As shown in FIG. 13B, in the state where the jackpot random number update process has been activated, the data of the program counter is “m”. In this case, the MPU 102 executes the process of step S501 by executing the instruction 1. When the execution of the instruction 1 is completed, the data of the program counter is incremented by one to "m + 1". In this case, the MPU 102 executes the process of step S502 by executing the instruction 2.

  When the execution of the instruction 2 is completed, the data of the program counter is incremented by one to "m + 2". In this case, the MPU 102 executes the determination process of step S503 by executing the conditional jump instruction JR.

  If the condition specified by the conditional jump instruction JR is satisfied, the jump instruction JP is executed to set the data of the program counter to "n". As a result, the MPU 102 reads an instruction 4 corresponding to the data of the program counter being "n" from the ROM 103, and executes the instruction 4. In this case, the process of step S505 is performed. Thereafter, the data of the program counter is incremented by 1 to be "n + 1". In this case, the MPU 102 executes the jump instruction JP1 for setting the data of the program counter to "m + 14". As a result, the processing after instruction 3, that is, the processing after step S 506 is executed thereafter.

  When the numerical information is set to the minimum value as described above, the program counter rewrite is executed first as an instruction to change the address when reading the program from the ROM 103 to an address different from the address according to the order so far. It needs to be changed. In this process, T is the time required for the program counter to be simply incremented by one in the previous order without executing any process for reading the instruction, that is, the time required for NOP is T. In the case, it is p × T. In addition, it is necessary to execute the jumped instruction (step S505). The time required for such processing is q × T. In addition, after executing the instruction, it is necessary to execute the jump instruction again to change the address in the case where the program is read out from the ROM 103 to an address different from the address according to the order in which the program is read. The time required for such processing is r × T. That is, after the determination in step S503 is affirmative and the process of step S505 is performed, the time required to shift to the process of step S506 is (p + q + r) × T.

  On the other hand, when the condition specified by the conditional jump instruction JR is not satisfied, the data of the program counter is incremented by one to be "m + 3". In this case, since the NOP is set as the instruction, no processing is executed. Thereafter, the NOP is read out each time the data of the program counter is sequentially incremented by 1, whereby the state where no processing is performed is continued. That is, until the data of the program counter becomes “m + 13”, the MPU 102 simply adds 1 to the data of the program counter without performing any processing. Then, when the data of the program counter becomes “m + 14”, the process proceeds to step S506.

  The data of the program counter “m + 3” to “m + 13” correspond to the process for time adjustment in step S504. That is, the process for time adjustment affects the content of the signal transmitted from the MPU 102 in a state where the setting process for the data to be referred to by the MPU 102 is not executed when the game is advanced. In the absence state, the process of repeating the program counter data by simply 1 is repeated. Then, the time adjustment process makes a negative determination in step S503, and the time required to shift to the process of step S506 is the same as the (p + q + r) × T.

  Specifically, in order to make a negative determination in step S503 and to shift to step S504, it is necessary to add 1 to the data of the program counter, so it takes T time. Therefore, in step S504, by executing the instructions “m + 3” to “m + 13” of the program counter, the progress of the process is waited for a period of (p + q + r−1) × T (note that This time includes the time required to move from step S504 to step S506).

  Returning to the explanation of FIG. 13A, after executing the processing of step S504 or step S505, in step S506, the above numerical information read out by the MPU 102 is the current update round of the big hit random number counter C1. It is determined whether or not it is the same as the numerical value information that has become the initial value. Specifically, the information of the initial value in the current update round stored in the RWM 104 is read out, and the numerical information after the process of step S502 or the numerical information after the process of step S505 is the same as the information of the initial value. It is determined whether or not.

  If a negative determination is made in step S506, the jackpot random number counter C1 is set by overwriting the numerical information after the process of step S502 or the numerical information after the process of step S505 in step S507. Thereafter, the jackpot random number update process is ended.

  On the other hand, when an affirmative determination is made in step S506, the current numerical value information held in the first initial value counter CN1 is read out in step S508, and the numerical information is read in step S502 in step S509. While overwriting the numerical value information after processing or the numerical information after processing of step S505, the area for storing the initial value of the update round in the RWM 104 is overwritten. Thereafter, in step S507, the value information after the process of step S509 is set by overwriting the jackpot random number counter C1 and the present jackpot random number updating process is ended.

  According to the configuration of the first pattern, the processing time of the jackpot random number update process and the jackpot in the case where the numerical information of the jackpot random number counter C1 is sequentially updated toward the maximum value which is one boundary of the numerical range From the outside of the MPU 102, the processing time of the jackpot random number updating process in the case where the numerical information is set to the minimum value which is the other boundary based on the numerical information of the random number counter C1 exceeding one boundary of the numerical range. It is difficult to identify or unidentifiable. Therefore, even if the processing time required for steps S201 to S205 is read out illegally using the above-mentioned illegal device A, the numerical information of the jackpot random number counter C1 becomes one boundary of the numerical range. It is difficult to identify or can not be identified. Therefore, even if it is attempted to obtain an illegal profit based on the illegal reading of the numerical information of the jackpot random number counter C1, it is possible to prevent that.

  In particular, according to this configuration, the processing time when the numerical value information of the big hit random number counter C1 is set to the minimum value, the process when the numerical information of the big hit random number counter C1 is sequentially updated toward one boundary Even if the processing time required for steps S201 to S205 is illegally read out using the above-mentioned illegal device A, it is difficult to specify with respect to time, or even if it can not be specified. It can not be specified which numerical information is. Therefore, it becomes possible to substantially invalidate the said fraud.

  Also, the numerical value of the jackpot random number counter C1 is simply increased by increasing the processing time of the jackpot random number update processing in the case where the numerical information of the jackpot random number counter C1 is sequentially updated toward the maximum value which is one boundary of the numerical range. Since the specific method for updating the information is the same, it is possible to achieve the above excellent effects while adopting the conventional processing method.

  Further, in the time adjustment process, the processing time of the NOP is hard to fluctuate because it is only read out a plurality of NOP instructions. Therefore, it is possible to achieve the above-mentioned excellent effects while suppressing the fluctuation of the processing time in the MPU 102. In addition, it is possible to add a delay time while suppressing the influence on the progress contents of the game. Furthermore, since the NOP is the instruction of the smallest unit in which the number of states is the smallest in the instruction executed by the MPU 102, the NOP becomes easy to design in order to equalize each processing time in the design stage of the pachinko machine 10.

  The configuration of the first pattern may be changed as follows.

  (1-1) A process for time adjustment on the basis of the processing time T in the case where the numerical information of the program counter is incremented by 1 without reading out the NOP instruction and executing no processing for the readout (step S504 The configuration is not limited to the configuration in which the time adjustment process is set based on the time T ′ of one state corresponding to one cycle of the clock circuit.

  Specifically, if the time taken to shift to the process of step S506 after performing the process of step S505 after making an affirmative determination in step S503 is s × T ′, the process for time adjustment is performed. The required time needs to be set to s × T′−T. In this case, s × T ′ is not a multiple of the processing time T in the case where the numerical information of the program counter is incremented by 1 without reading out the NOP instruction and executing no processing for the readout. Conceivable. In this configuration, in the case where only NOP is repeated in the time adjustment process, the processing time in the case where the numerical information of the jackpot random number counter C1 is set to the minimum value and the numerical information of the jackpot random number counter C1 is one. Although the processing time in the case of being sequentially updated toward the boundary can not be made the same, it is possible to reduce the time difference between the two.

  On the other hand, in a configuration in which s × T ′ is not a multiple of the processing time T, an instruction other than the NOP is set as at least a part of the instruction set in the time adjustment process. The processing time when the numerical value information of C1 is set to the minimum value and the processing time when the numerical information of the big hit random number counter C1 is sequentially updated toward one of the boundaries may be the same. However, the instruction other than the NOP affects that the setting process for the data to be referred to by the MPU 102 is not performed when advancing the game, that is, the content of the signal transmitted from the MPU 102 is affected. It is preferable not to give. For example, a process of resetting data of a program counter to current data as an instruction or a process of setting "1" in an area which is a general purpose register and does not affect the subsequent process of the MPU 102 can be considered.

  As in the first pattern, the processing time required to make a positive decision in step S503 and to shift to the processing of step S506 is the configuration in which an instruction other than NOP is set as described above. The present invention may be applied to a configuration that is a multiple of the processing time T.

  (1-2) In order to equalize the processing time, when the negative determination is made in Step S503 and the process proceeds to Step S506, the first time adjustment processing is executed, and the positive determination is made in Step S503. Then, when shifting to the process of step S506, the second time adjustment process may be executed, and the delay time may be different between the first time adjustment process and the second time adjustment process.

  (1-3) The time adjustment process is not performed before the process proceeds to step S506, but after the negative determination in step S503, and is performed after step S506 and before the process of step S205. It may be configured to be executed. In this case, for example, when a negative determination is made in step S503, “1” is set to the flag corresponding thereto, and after the process of step S507 is performed, before the process proceeds to step S203, the step In the middle of S203, between step S203 and step S204, or between step S204 and step S205, the time adjustment processing may be executed on condition that the above flag is set to "1". Good. In this case, it is necessary to set the delay time in the time adjustment process in consideration of the time required to set the flag and the time required to determine the flag.

<Second pattern>
Next, the configuration of the second pattern serving as a countermeasure against the above-mentioned fraudulent activity will be described. The processing configuration of the lottery random number updating process (step S202) is the same as that of the first pattern.

  FIG. 14A is a flowchart showing the jackpot random number updating process in the second pattern.

  First, at step S601, the numerical information held in the big hit random number counter C1 is read out to the register of the MPU 102, and at step S602, the read numerical information is incremented by one to be the next numerical information. Thereafter, in step S603, it is determined whether the numerical information of the result updated in step S602 is less than or equal to the maximum value (specifically, it is determined whether or not it is less than "599").

  If it is equal to or less than the maximum value (step S603: YES), the process proceeds to step S606 without executing the processes of steps S604 and S605. On the other hand, if it exceeds the maximum value (step S603: NO), the process proceeds to step S604, and similarly to step S505, the numerical information updated in step S602 is numerical information of the minimum value, specifically, Set to "0".

  Here, in the present pattern 2, when the numerical information of the big hit random number counter C1 is sequentially updated toward the maximum value which is one boundary of the numerical range, an affirmative determination is made in step S603. That is, as a result of reading and executing the conditional jump instruction JR, the jump instruction of the program counter is executed. On the other hand, when the numerical value information of the jackpot random number counter C1 exceeds the one boundary of the numerical range and the numerical information is set to the minimum value which is the other boundary, a negative determination is made in step S603. . That is, as a result of reading and executing the conditional jump instruction JR, data of the program counter is incremented by one without executing the jump instruction.

  In this case, the processing time required to make a positive determination in step S603 and to shift directly to step S606 is longer than the processing time required to make negative determination in step S603 and to complete step S604. There is. Therefore, the processing for time adjustment of step S605 is set at the timing after the execution of step S604 and before the execution of step S606. Due to this time adjustment process, the processing time required to make a negative determination in step S603 and to execute step S606 after executing step S604 is delayed, and the processing time of the delayed result is positive in step S603. The determination is made to be the same as or substantially the same as the processing time required to directly shift to step S606.

  By the way, the processing contents of the above-mentioned process for time adjustment are the processing time in the case of making affirmation determination in step S603 and shifting to step S606 and the negative determination in step S603 to complete the processing of step S604. In order to fill the time difference between the required processing time and the processing time required to shift from step S605 to step S606, the configuration may be such that the NOP instruction is read and processing is not repeated as in step S504. It may be configured to execute an instruction other than the setting process for data to be referred to by the MPU 102 when the game is advanced.

  The processing contents of steps S606 to S609 are the same as the processing contents of steps S506 to S509, and therefore the description thereof is omitted.

  According to the configuration of the second pattern, as a result of the determination processing in step S603, by executing the jump instruction of the program counter, the address when reading the program from the ROM 103 is different from the address in accordance with the order up to that The target to be changed to the address is the side that leaves the updated numerical information in step S602 as it is. On the other hand, as a result of the determination processing in step S603, the target in which the address in the case of reading the program from the ROM 103 without executing the jump instruction of the program counter is the address according to the order up to that is the numerical value after the update in step S602. It is the side that rewrites the information to the minimum value. Then, the processing for time adjustment is executed on the latter side, which is the side where the processing time becomes shorter, in the flow of both of these processing. As a result, while shortening the time required for each process of the jackpot random number update process, it is possible to prevent an action to obtain an illegal profit based on the illegal reading of the numerical information of the jackpot random number counter C1. .

  Furthermore, according to the present configuration, the processing time required to set the numerical information of the jackpot random number counter C1 to the minimum value using the processing time required to execute the jump instruction of the program counter, and the numerical information Since the time difference from the processing time in the case of sequentially updating is reduced, the number of repetitions of NOP set for the process for time adjustment can be suppressed accordingly. Therefore, it is possible to prevent the above-mentioned fraudulent acts while reducing the program capacity.

  The configuration of the second pattern may be changed as follows.

  (2-1) After making an affirmative determination in step S603 and executing the jump instruction of the program counter, the processing time required to shift to step S606 makes a negative determination in step S603, and the program counter If it is shorter than the processing time required to move to step S606 after executing step S604 without executing the jump instruction, as shown in FIG. 14B, the program is positively determined in step S603 and the program is executed. The time adjustment process of step S605 may be performed on the side where the jump instruction of the counter is executed, and the jump instruction of the program counter may be further executed to shift to step S606. Even in this case, while shortening the time required for each processing of the jackpot random number update processing, the act of obtaining an illegal profit based on the illegal reading of the numerical information of the jackpot random number counter C1 is prevented. Is possible.

  (2-2) After making a positive determination in step S603 and executing the jump instruction of the program counter, the processing time required to proceed directly to step S606 makes a negative determination in step S603 to make the program counter In the configuration that is the same as or substantially the same as the processing time required to shift to step S606 after executing step S604 without executing the jump instruction of step S, the processing for time adjustment in step S605 may not be performed. .

  (2-3) The same configuration as the above (1-2) may be applied to the configuration of the second pattern, and the configuration similar to the above (1-3) may be the configuration of the second pattern May be applied to

<Third pattern>
Next, the configuration of the third pattern serving as a countermeasure against the above-mentioned fraudulent activity will be described. The processing configuration of the lottery random number updating process (step S202) is the same as that of the first pattern.

  FIG. 15 is a flowchart showing the jackpot random number updating process in the third pattern.

  First, in step S701, the numerical information held in the big hit random number counter C1 is read out to the register of the MPU 102, and in step S702, 1 is added to update the read numerical information so as to be the next numerical information. Thereafter, in step S703, it is determined whether the numerical information of the result updated in step S702 exceeds the maximum value (specifically, "599") of the jackpot random number counter C1 (specifically, " It is judged whether it is 600 "or more).

  If it does not exceed the maximum value (step S703: NO), the process directly proceeds to step S706. In this case, the jump instruction of the program counter is not executed, and the data of the program counter is incremented by one, and the process proceeds to step S706.

  On the other hand, if the maximum value is exceeded (step S703: YES), the numerical information updated in step S702 is set to the numerical information of the minimum value, specifically, "0" in step S704. Thereafter, after the time adjustment process is executed in step S705, the process proceeds to step S706. The contents of this time adjustment process will be described later. Incidentally, upon transition to step S704 and transition to step S706, a jump instruction of the program counter is executed.

  In step S706, it is determined whether the numerical information read out by the MPU 102 is the same as the numerical information that has become the initial value in the present update round of the big hit random number counter C1. Specifically, the information of the initial value in the current update round stored in the RWM 104 is read out, and the numerical information after the process of step S702 or the numerical information after the process of step S704 is the same as the information of the initial value. It is determined whether or not.

  When negative determination is carried out in step S706, it progresses to step S707. In this case, the jump instruction of the program counter is not executed, and the data of the program counter is incremented by one, and the process proceeds to step S707. In step S707, the jackpot random number counter C1 is set by overwriting the numerical information after the process of step S702 or the numerical information after the process of step S704. Thereafter, the jackpot random number update process is ended.

  On the other hand, when an affirmative determination is made in step S706, the process proceeds to step S708. In this case, a jump instruction of the program counter is executed to shift to step S708. In step S708, the current numerical value information held in the first initial value counter CN1 is read out, and in the subsequent step S709, the numerical value information is converted to the numerical information after the process of step S702 or the numerical information after the process of step S705. In addition to overwriting, an area for storing the initial value of the update round in the RWM 104 is overwritten. Thereafter, in step S 707, the numerical information after the process of step S 709 is set by overwriting the jackpot random number counter C 1, and then the present jackpot random number updating process is ended.

  Here, the time adjustment process in step S705 sets the numerical information exceeding one boundary of the numerical range to the other boundary after updating the numerical information read out from the big hit random number counter C1 by one according to the update order In this case, that is, the processing time required to set the numerical value information of the big hit random number counter C1 to “0” which is the minimum value, the result of updating the numeric information read from the big hit random number counter C1 by one in the update order The processing time of the jackpot random number updating process in the former case is shorter than the processing time required to set the initial value of the new renewal round to the jackpot random number counter C1 when it is the initial value in the renewal round of This is a process for approaching the processing time of the jackpot random number update process in the latter case. More specifically, the processing time for the jackpot random number update process in the former case is the same as or substantially the same as the processing time for the jackpot random number update process in the latter case.

  By the way, the processing content of the time adjustment processing is the processing time required to make a positive determination in step S703 and shift to step S704, the processing time required to complete the processing in step S704, and after completion of step S705 The sum of the processing time required to shift to step S706 at step S706 and the processing time required to shift to step S707 after making a negative determination at step S706 (hereinafter also referred to as the first time) Processing time required to move to step S706 with negative determination, processing time required to move to step S708 with positive determination at step S706, processing time required to complete the process of step S708, step Processing time required to complete the process of S709, and after completion of step S709. In order to fill the time difference with the sum of the processing time required to shift to step S 707 (hereinafter also referred to as the second time), repeat the process of not executing the process by reading out the NOP instruction as in step S 504 above. It is good also as composition, and it is good also as composition which performs a setup processing about data which will be referred by MPU102 when it is not NOP and advances a game, and not performed.

  According to the configuration of the third pattern, the processing time of the jackpot random number updating process in the case where the numerical information of the jackpot random number counter C1 is set to the minimum value, and the numerical information of the jackpot random number counter C1 is the initial value of the new update roundabout The processing time of the jackpot random number update process in the case of setting to is difficult or impossible to identify from the outside of the MPU 102. Therefore, it is difficult to specify that the numerical information of the jackpot random number counter C1 has become the initial value or it is difficult to specify that the processing time required for the steps S201 to S205 is illegally read using the illegal device A. It becomes impossible. Therefore, even if it is attempted to obtain an illegal profit based on the illegal reading of the numerical information of the jackpot random number counter C1, it is possible to prevent that.

  Further, according to the present configuration, the processing time of the big hit random number update process in the case where the numerical information of the big hit random number counter C1 is sequentially updated toward one boundary of the numeric range is longer than that of the conventional configuration. It is possible to prevent the above-mentioned fraudulent acts without making it happen.

  The configuration of the third pattern may be changed as follows.

  (3-1) A process for time adjustment when the initial value of a new update round is set as numerical information of the big hit random number counter C1 when the first time is longer than the second time May be performed.

  (3-2) If it is determined in step S706 that the numerical information is different from the current initial value, a negative determination is made in step S706, that is, as a result of the determination processing in step S706, the program counter In the configuration in which the processing of step S 708 and step S 709 is executed when the jump instruction is not executed and the data of the program counter is incremented by one, the corresponding second time corresponds to the first time. It may be the same or substantially the same. In this case, the time adjustment process of step S705 may not be executed.

  (3-3) The same configuration as the above (1-2) may be applied to the configuration of the third pattern, and the configuration similar to the above (1-3) may be the configuration of the above third pattern May be applied to

<Fourth pattern>
Next, the configuration of the fourth pattern serving as a countermeasure against the above-mentioned fraudulent activity will be described.

  FIG. 16 is a flowchart showing the lottery random number updating process in the fourth pattern.

  First, in step S801, a jackpot random number updating process for periodically updating the numerical information of the jackpot random number counter C1 is executed. In this case, the jackpot random number updating process has a processing configuration in which the time adjustment process of step S504 is not executed in the jackpot random number updating process (FIG. 13A) in the first pattern. That is, the processing time of step S201 to step S205 when the numerical value information of the big hit random number counter C1 is set to the minimum value, the numerical information of the big hit random number counter C1 is sequentially updated, or the numerical information of the big hit random number counter C1 is The processing for making the processing time the same as or substantially the same as the processing time of steps S201 to S205 when the initial value is set is not executed.

  Instead, in steps S802 to S804, processing for irregularly processing the processing time in steps S201 to S205 is executed. Specifically, first, in step S802, information on the number of repetitions is acquired and stored in the register of the MPU 102.

  The information on the number of repetitions is stored in a repetition number counter provided in the RWM 104, and the repetition number counter is a loop counter that loops within a predetermined numerical range. In this case, the minimum value of the numerical range of the repetition number counter is “0”, but the minimum value may be 1 or more. By setting the minimum value to 1 or more, the delay time is surely set in the delay process of steps S802 to S804.

  The numerical information of the repetition number counter is updated in the remaining processing of step S110 to step S115 in the main processing (FIG. 8). In this case, since the residual processing is performed irregularly as described above, the information on the number of repetitions becomes irregular.

  Note that in order to make the information on the number of repetitions irregular, the present invention is not limited to the configuration that uses the repetition number counter as described above and updates its numerical information by the remaining process, and the control unit of the MPU 102 Alternatively, information on the number of repetitions may be sequentially updated in a separately operating circuit, and the information on the number of repetitions held at that time may be provided to the control unit of the MPU 102 at the timing of step S802. This circuit may be made into one chip as the MPU 102, or may be made into a separate chip from the MPU 102. Further, the information on the number of repetitions may be sequentially updated using the refresh register.

  In the subsequent step S803, the acquired information on the number of repetitions is updated so as to be decremented by 1, and it is determined in step S804 whether or not the information on the number of repetitions after the update is "0". If a negative determination is made in step S804, the processing in step S803 and step S804 is performed again, while if a positive determination is made in step S804, the processing in step S805 to step S807 is performed, and then the process is performed. The lottery random number updating process ends. The processing contents of steps S <b> 805 to S <b> 807 are the same as the processing contents of steps S <b> 402 to S <b> 404.

  As described above, the irregular delay processing is performed in steps S802 to S804 using the information on the number of repetitions, and the timing at which the numerical information of the jackpot random number counter C1 is set to the minimum value is incorrect. Even if it tries to specify by grasping processing time of step S201-step S205 with device A, it becomes difficult to do it.

  Here, based on the execution of the irregular delay processing as described above, the numerical information of the big hit random number counter C1 is selected by the delay processing in order to make it difficult to specify the timing when the minimum value is set. The processing time of the jackpot random number updating process when the numerical information of the jackpot random number counter C1 is set to the minimum value among the plurality of types of delay times, and the numerical information of the jackpot random number counter C1 is set to the minimum value It is preferable that a delay time that is equal to or more than the time difference from the processing time of the jackpot random number update process when being set in a different mode is included.

  More preferably, the processing time of the jackpot random number updating process and the jackpot random number counter C1 in the case where the numerical information of the jackpot random number counter C1 is set to the minimum value among the plurality of types of delay times selected in the delay processing A delay time that is equal to or greater than the time difference from the processing time of the jackpot random number update process when numerical information is sequentially updated toward the maximum value is included.

  Also, instead of or in addition to the configuration, the processing time of the jackpot random number updating process when the numerical information of the jackpot random number counter C1 is set to the minimum value among the plurality of types of delay times selected in the delay processing. A delay time that is equal to or greater than the processing time of the jackpot random number update process when the numerical information of the jackpot random number counter C1 is set to the initial value may be included. Thereby, even if the processing time in steps S201 to S205 is read illegally by the illegal device A, either setting of the minimum value of the big hit random number counter C1 or setting of the initial value of the big hit random number counter C1 is executed. You will not be able to identify

  The configuration of the fourth pattern may be changed as follows.

  (4-1) The irregular delay process shown in steps S802 to S804 is not necessarily performed immediately after the process of step S801, and may be performed within the range of steps S201 to S205. Is optional. For example, the irregular delay process may be executed at the start of the lottery random number update process, or the irregular delay process may be executed at the end of the lottery random number update process.

<Fifth pattern>
Next, the configuration of a fifth pattern serving as a countermeasure against the above-mentioned fraudulent activity will be described. The processing configuration of the lottery random number updating process (step S202) is the same as that of the first pattern.

  FIG. 17 (a) is a flowchart showing the jackpot random number updating process in the fifth pattern, FIG. 17 (b) is a flowchart showing the reach random number updating process in the fifth pattern, and FIG. 17 (c) is the fifth It is a flowchart which shows the electronic connector random number update process in the pattern of.

  As shown in FIG. 17A, in the jackpot random number update process of this pattern, the process configuration for time adjustment in step S504 is not executed in the jackpot random number update process (FIG. 13A) of the first pattern. It has become. That is, in steps S901 to S903, processing similar to that in steps S501 to S503 is performed, and in step S904, processing similar to that in step S505 is performed, and in steps S905 to S908, steps S506 to S509 are performed. Perform the same process.

  As shown in FIG. 17B, in the reach random number updating process of this pattern, first, in step S911, the numerical information held in the reach random number counter C3 is read out to the register of the MPU 102, and the read out is performed in step S912. The numerical value information is incremented by 1 to be updated to the next numerical value information. Thereafter, in step S913, it is determined whether or not the numerical information of the result updated in step S912 exceeds the maximum value (specifically, "238") of the reach random number counter C3 (specifically, " It is judged whether or not it is 238 "or more).

  If it does not exceed the maximum value (step S913: NO), the process directly proceeds to step S914. In this case, the jump instruction of the program counter is not executed, and the data of the program counter is incremented by one, and the process proceeds to step S914. In step S914, the numerical information after the process of step S912 is set by overwriting the reach random number counter C3. Thereafter, the reach random number update process is ended.

  If it exceeds the maximum value (step S 913: YES), the numerical value information updated in step S 912 is set to the numerical value information of the minimum value, specifically, “0” in step S 915. In the subsequent step S916, the reach side time adjustment process is executed. The processing content of the time adjustment processing will be described later. Thereafter, in step S914, the numerical information after the process of step S915 is set by overwriting the reach random number counter C3, and the reach random number update process is ended. Incidentally, upon the transition to step S915 and the transition to step S914, the jump instruction of the program counter is executed.

  As shown in FIG. 17C, in the electronic pattern random number update process of this pattern, first, in step S921, the numerical information held in the electronic pattern random number counter C4 is read out to the register of the MPU 102, and in step S922. The read out numerical information is incremented by 1 so as to be the next numerical information. Thereafter, in step S923, it is determined whether the numerical information of the result updated in step S922 exceeds the maximum value (specifically, "250") of the electronic random number counter C4 (specifically, It is judged whether it is "250" or more).

  If it does not exceed the maximum value (step S 923: NO), the process directly proceeds to step S 926. In this case, the jump instruction of the program counter is not executed, and the data of the program counter is incremented by one, and the process proceeds to step S926.

  If it exceeds the maximum value (step S 923: YES), in step S 924, the numerical value information updated in step S 922 is set to the numerical value information of the minimum value, specifically, “0”. In the subsequent step S 925, processing for time adjustment on the electronic combination side is executed. The processing content of the time adjustment processing will be described later. Thereafter, the process proceeds to step S926. Incidentally, upon transition to step S924 and transition to step S926, a jump instruction of the program counter is executed.

  In step S926, it is determined whether the numerical value information read out by the MPU 102 is the same as the numerical value information that has become the initial value in the current update round of the electronic-composition random number counter C4. Specifically, the information of the initial value in the present update round stored in the RWM 104 is read out, and the numerical information after the process of step S922 or the numerical information after the process of step S925 is the same as the information of the initial value. It is determined whether or not.

  If a negative determination is made in step S926, in step S927, numerical value information after the processing in step S922 or numerical information after the processing in step S925 is set by overwriting the electronic random number counter C4. Thereafter, the jackpot random number update process is ended.

  On the other hand, when an affirmative determination is made in step S926, the current numerical value information held in the third initial value counter CN3 is read out in step S928, and the numerical information is processed in step S922 in step S929. While overwriting the subsequent numerical information or the numerical information after the process of step S 925, the area for storing the initial value of the update round in the RWM 104 is overwritten. Thereafter, in step S 927, the numerical information after the process of step S 929 is set by overwriting the electronic random number counter C 4, and then the present jackpot random number updating process is ended.

  In the time adjustment process on the reach side in step S916, step S201 to step S205 in the case where the numerical information of the reach random number counter C1 is not set to the initial value and the numerical information of the reach random number counter C3 is set to the initial value. In order to make the processing time of step S201 to step S205 approach when the numerical information of the big hit random number counter C1 is set to the initial value and the numerical information of the reach random number counter C3 is not set to the initial value, This is a process for delaying the processing time of the reach random number update process when the numerical value information of C3 is set to the initial value. More specifically, it is a process for making the former processing time the same as the latter processing time.

  In addition, the processing for time adjustment on the side of the electronic part in the step S925 is a step in the case where the numerical information of the electronic part random number counter C4 is set to the initial value without setting the numerical information of the big hit random number counter C1 to the initial value In order to approach the processing time of step S201 to step S205 when the numerical information of the big hit random number counter C1 is set to the initial value and the numerical information of the electronic random number counter C4 is not set to the initial value. It is the processing for delaying the processing time of the electronic random number updating process in the case where the numerical information of the electronic random number counter C4 is set to the initial value. More specifically, it is a process for making the former processing time the same as the latter processing time.

  Here, the large random number counter C1 has two bytes set in the RWM 104, whereas the reach random number counter C3 and the electronic combination random number counter C4 each have one byte set in the RWM 104. In this case, when setting the numerical information of the jackpot random number counter C1, the reach random number counter C3 and the electronic part random number counter C4 to the minimum value, their “0” clear processing is executed, but the “0” clear is performed. The processing is performed not on a bit basis but on a byte basis. Then, the processing time of the process (step S904) for setting the big hit random number counter C1 to the minimum value is longer than the processing time of the process (step S915) for setting the reach random number counter C3 to the minimum value. This is longer than the processing time of the process (step S 924) for setting the random number counter C 4 to the minimum value. The same applies to the jackpot type counter C2, and since 1 byte is set in the jackpot type counter C2 in the RWM 104, the processing time for setting the jackpot random number counter C1 to the minimum value is the jackpot type counter C2 Is longer than the processing time for setting the value to the minimum value. Therefore, by reading the processing time of step S201 to step S205 using the illegal device A, the jackpot random number counter C1, the jackpot type counter C2, the reach random number counter C3 and the random number update process for lottery (step S202) When any one of the electronic random number counters C4 is set to the minimum value, it becomes possible to specify whether or not it is the jackpot random number counter C1.

  On the other hand, the random number updating process for lottery (step S202) is performed by executing the process for adjusting the time on the reach side (step S916) and the process for adjusting the time on the electronic worker side (step S925) as described above. When only the big hit random number counter C1 is set to the minimum value, only the reach random number counter C3 is set to the minimum value, and only the electric random number counter C4 is set to the minimum value. Even if the processing time of steps S201 to S205 is read illegally, it becomes impossible to specify which of the cases. Therefore, even if it is attempted to obtain an illegal profit based on the illegal reading of the numerical information of the jackpot random number counter C1, it is possible to prevent that.

  By the way, the specific processing contents of the above-mentioned time adjustment processing do not execute the processing by reading out the NOP instruction as in the above-mentioned step S 504 so as to fill in the time difference between the processing times for achieving equalization of processing time. It may be configured to repeat the process, or may be configured to execute an instruction other than the NOP and for which the setting process for data to be referred to by the MPU 102 is not executed when the game is advanced.

  The configuration of the fifth pattern may be changed as follows.

  (5-1) Only one of the time adjustment process on the reach side and the time adjustment process on the electronic combination side may be executed.

  (5-2) Also in the jackpot type updating process, when the numerical value information of the jackpot type counter C2 is set to the minimum value, the process for time adjustment on the type side may be executed. In this case, step S201 to step S205 in the case where the numerical value information of the big hit random number counter C1 is not set to the initial value and the numerical information of the big hit type counter C2 is set to the initial value In order to approximate the processing time of step S201 to step S205 when the numerical information of the big hit random number counter C1 is set to the initial value and the numeric information of the big hit type counter C2 is not set to the initial value, the big hit type counter The processing time of the jackpot type updating process in the case where the numerical value information of C2 is set to the initial value may be delayed. More specifically, the process for adjusting the time on the type side may be set as a process for making the former processing time the same as or substantially the same as the latter processing time. As described above, when the time adjustment process on the type side is executed, the reach adjustment process on the reach side and the time adjustment process on the electronic work side may not be executed, but the numerical information of the jackpot random number counter C1 is minimum. In order to make it difficult to specify the timing to be set to the value, it is preferable that one of the reach adjustment processing and the electronic adjustment processing be also performed. It is more preferable to set it as

  (5-3) The time required for the process of step S904 and the step S915 by making the number of bytes allocated as the big hit random number counter C1 in the RWM 104 equal to the number of bytes allocated as the reach random number counter C3 in the RWM 104 The time required for the process may be the same or substantially the same. In this case, even if the process in step S916 is not performed, either the large random number counter C1 alone is set to the minimum value or the reach random number counter C3 alone is set to the minimum value Even if the processing time of step S201 to step S205 is read illegally, it can not be specified. The configuration may be applied to the jackpot type counter C2 or the electronic combination random number counter C4.

  (5-4) Instead of executing the process of step S916, in step S915, the process of setting the reach random number counter C3 to the minimum value, that is, the process of clearing the corresponding 1-byte area in the RWM 104 twice. It may be configured to execute. In this case, when the reach random number counter C3 is set to the minimum value, the number of bytes targeted for the clearing process is the same as the number of bytes targeted for the clearing process when the large per random number counter C1 is set to the minimum value. Therefore, even if the process of step S916 is not performed, which of the case where only the big hit random number counter C1 is set to the minimum value and the case where only the reach random number counter C3 is set to the minimum value is made. Even if the processing time of step S201 to step S205 is read illegally, it can not be specified. The configuration may be applied to the jackpot type counter C2 or the electronic combination random number counter C4.

<Sixth pattern>
Next, the configuration of the sixth pattern serving as a measure against the above-mentioned fraud will be described.

  In the sixth pattern, the processing configuration of the timer interrupt processing is different from the processing configuration of the timer interrupt processing (FIG. 9) described above. FIG. 18 is a flowchart showing timer interrupt processing in the present pattern.

  As shown in FIG. 18, in the timer interrupt process, first, in step S1001, a lottery random number update process is performed, and then in step S1002, a power failure information storage process is performed. Thereafter, in steps S1003 to S1023, the same processes as steps S203 to S223 in the timer interrupt process (FIG. 9) are executed.

  That is, in this pattern, the lottery random number update process is not included between the power failure information storage process (step S1002) and the game stop determination process (step S1005). Therefore, even if the processing time between these processes is read out illegally, it is not possible to specify the timing at which the numerical information of the jackpot random number counter C1 is set to the minimum value. Further, the lottery random number updating process is not included between the processes for the MPU 102 to perform input / output through the input / output port 102 a within the range of one process of the timer interrupt process. Therefore, within the range of one processing of the timer interrupt processing, the processing time between the processing relating to one input / output and the processing relating to the subsequent input / output is improper except between step S1002 and step S1005. Even if read, it is not possible to specify the timing at which the numerical information of the jackpot random number counter C1 is set to the minimum value.

  However, if the processing time between the processing related to one input / output in one processing cycle of timer interrupt processing and the processing related to the same or different input / output in the next processing cycle is illegally read, the processing The time will include lottery random number update processing. On the other hand, the lottery random number updating process is set to be executed at a timing earlier than the process related to the first input / output in the timer interrupt process. That is, after the remaining process in step S110 to step S115 of the main process (FIG. 8), and before the process related to input / output to be executed first (process related to at least one of input and output) , Lottery random number updating processing is executed.

  As already described, the remaining process is a non-periodic process in which the presence or absence of execution and the number of times of execution between the two timer interrupt processes fluctuate irregularly according to the process completion time of each timer interrupt process. The processing time from the completion of one timer interrupt process to the execution of the process related to the first input / output in the timer interrupt process of the next process cycle fluctuates irregularly. Then, even if the processing time between the processing related to one input / output in one processing cycle of timer interrupt processing and the processing related to the same or different input / output in the next processing cycle is read illegally, It becomes difficult to specify whether or not the numerical information of the big hit random number counter C1 is set to the minimum value in the random number updating process for drawing, or it becomes impossible to specify.

  Further, in this configuration, the timing when the big hit random number counter C1 is set to the initial value, the timing when the big hit type counter C2 is set to the minimum value, the timing when the big hit type counter C2 is set to the initial value, reach random number counter Also for the timing when C3 is set to the minimum value, the timing when the random number counter C4 is set to the minimum value, and the timing when the electronic part random number counter C4 is set to the initial value, the processing time is incorrect as described above. It becomes difficult to identify or can not be identified only by reading.

  Incidentally, the processing configuration of the lottery random number updating process in the present pattern is the same as that of the first pattern. In addition, the time adjustment process as described in each of the above-described patterns, including the jackpot random number update process, is not performed.

  The configuration of the sixth pattern may be changed as follows.

  (6-1) In the configuration in which the random number updating process for lottery (that is, the jackpot random number updating process) is included between the remaining process and the process related to the input / output to be executed first, the random number updating for lottery It is not essential that the process is executed at the first timing of the timer interrupt process, and the process relating to input / output, that is, a signal for selecting a driver for input or a signal for selecting a driver for output is output from MPU 102 Random number update process for lottery under the condition that it is not a process, it is not a process in which a command is output from MPU 102 to another control device, and it is not a process in which a signal is output from MPU 102 to a game hall management computer Other processes may be executed prior to the process. For example, the process of reading predetermined data from the ROM 103 may be performed prior to the lottery random number update process.

  (6-2) In the timer interrupt process shown in FIG. 19, first, at step S1101, the power failure information storage process is executed as in step S201. Thereafter, in steps S1102 to S1120, processing similar to that of steps S203 to S221 is performed. Then, after the lottery random number updating process is executed in step S1121, the interrupt end declaration is set in step S1122, and the interrupt permission is set in step S1123. Thereafter, this timer interrupt processing is ended. In the case of this processing configuration, after the processing (step S1119) related to the predetermined input / output is performed, the remaining processing can be executed without the processing related to the other input / output being performed. A random number updating process for lottery is executed between the process and the remaining process. Thereby, similarly to the pattern 6, the processing time between the processing related to one input / output in one processing time of timer interrupt processing and the processing related to the same or different input / output in the next processing time Even if it is read illegitimately, it becomes difficult or impossible to specify whether or not the numerical information of the jackpot random number counter C1 is set to the minimum value in the random number updating process for lottery.

  (6-3) As shown in FIG. 20 and FIG. 21, the game is played in each of the normal process in which the first process is periodically executed and the timer interrupt process in which the first process is periodically executed as well. The same countermeasure as the sixth pattern may be adopted in the processing configuration in which the processing necessary for advancing is distributed and set.

  Specifically, the normal process is performed after the process of step S109 in the main process (FIG. 8) is performed. Then, as shown in FIG. 20, the same process as step S207 is performed in step S1201, and the same process as step S203 to step S204 is performed in steps S1202 to S1203, and steps S1204 to S1204 are performed. In S1213, the same processing as the above-described steps S212 to S221 is performed. Thereafter, in step S1214, it is determined whether the power failure flag is set to "1". The power failure flag is set to “1” when the occurrence of a power failure is identified in the power failure information storing process of step S1302 in the timer interrupt process (FIG. 21).

  If "1" is not set in the power failure flag, it is determined in step S1215 whether it is time to execute the next normal process, that is, a predetermined time (specifically, 4 msec) from the start of the previous normal process. It is determined whether it has elapsed. Then, the remaining processes of steps S1216 to S1219 are repeatedly executed until the start time of the normal process is reached. The processing content of step S1216 to step S1219 is the same as that of step S110 to step S115.

  On the other hand, when it is determined that the power failure flag is set to “1” in step S1214, the power failure process after step S1220 is executed. That is, in step S1220, the generation of timer interrupt processing is prohibited, and then the RWM determination value is calculated and stored in step S1221, and after the access to RWM 104 is prohibited in step S1222, the power is completely shut off and processing is performed. Continues an infinite loop until it can not execute.

  In the timer interrupt process, as shown in FIG. 21, first, in step S1301, a lottery random number update process is executed. The contents of this process are the same as those in step S1001. Thereafter, in step S1302, the same process as step S201 is performed, and in step S1303, the same process as step S205 is performed. In steps S1304 to S1307, the process similar to step S208 to step S211. After execution of the timer interrupt processing, the timer interrupt processing is terminated.

  With the above processing configuration, in the configuration in which the processing for controlling the progress of the game is dispersedly set in each of the normal processing and the timer interrupt processing, the processing is performed after the remaining processing and is performed first after that Prior to the process related to the input / output to be performed (the process related to at least one of the input and the output), the random number updating process for lottery (the jackpot random number updating process) is executed. Thereby, even if the processing time between the processing related to one input / output in one processing cycle of the timer interrupt processing and the processing related to the same or different input / output in the next processing cycle is illegally read. It becomes difficult to specify whether or not the numerical value information of the jackpot random number counter C1 is set to the minimum value in the random number updating process for drawing, or it becomes impossible to specify.

  The lottery random number updating process may be executed after the process related to the final input / output in the timer interrupt process (FIG. 21).

  (6-4) In the jackpot random number updating process, processing when the numerical information of the jackpot random number counter C1 is sequentially updated toward the maximum value and the minimum when the numerical information of the jackpot random number counter C1 exceeds the maximum value The processing in the case of setting to a value is set separately, and a configuration different from the processing relating to the update of the jackpot random number counter C1 may be present among the processing. In this case, the process for setting at least the minimum value is after the remaining process in step S110 to step S115, and is a process related to input / output that is initially executed after that (related to at least one of input and output It is preferable to be performed before processing (processing). Alternatively, in a configuration in which the above-mentioned remaining process can be executed without the process related to another input / output being performed after the process related to the predetermined input / output is performed, the process related to the predetermined input / output and the remaining process Preferably, at least the process of setting the minimum value is performed.

  As described above, by adopting any one of the first pattern to the sixth pattern, it is possible to use the fraudulent device A to perform processing related to one input / output in the MPU 102 and then one input / output thereafter. Even if the processing time until the processing related to the above is illegally read, it is possible to make it difficult or impossible to specify the timing at which the numerical information of the big hit random number counter C1 becomes the minimum value.

  In addition, if it is any one of the first pattern to the sixth pattern, it is not necessary to directly manipulate the numerical information of the jackpot random number counter C1 in order to suppress the illegal activity, but to update timing of the numerical information. Since only delaying or randomizing is performed, inconveniences are less likely to occur in regard to the determination of success or failure using the numerical information of the jackpot random number counter C1.

  In this case, the pachinko machine 10 has the configuration of any one of the first pattern to the sixth pattern, but may have configurations relating to a plurality of patterns simultaneously. For example, any of the configuration according to the first pattern, the configuration according to the second pattern, the configuration according to the third pattern, and the configuration according to the fifth pattern, and the configuration according to the fourth pattern And at least one of the configurations according to the sixth pattern may be provided simultaneously.

  In addition, it is not limited to the description content of embodiment mentioned above, A various deformation | transformation improvement is possible within the range which does not deviate from the meaning of this invention. For example, it may be changed as follows. Incidentally, the configuration of the other embodiment described below may be applied individually to the configuration of the above embodiment, or may be applied in combination.

  -Instead of the configurations of the first to sixth patterns, a CPU or dedicated circuit for updating numerical information of the big hit random number counter C1 is provided separately from the control unit of the MPU 102, and the numeric value of the big hit random number counter C1 The update of information, the setting of the minimum value, and the setting of the initial value when starting the update round may be performed independently of the control unit of the MPU 102. When the control unit of the MPU 102 executes the determination processing using the numerical information of the big hit random number counter C1, the numerical information at that time may be acquired from the other control unit. In this configuration, by making the time required for provision of numerical information from the separate control unit to the MPU 102 constant (the same or substantially the same between different provision timings), it is possible to obtain a predetermined value using the unauthorized device A. Even if the processing time between the processes in is acquired, it is possible to make it difficult or impossible to specify the timing at which the numerical information of the jackpot random number counter C1 becomes the minimum value.

  Further, in this configuration, although the separate control unit may be provided as a separate chip from the control unit of the MPU 102, the value after the update of the separate control unit is illegally accessed to both communication paths. In order to prevent an act of illegally acquiring information, it is preferable that the separate control unit be integrated with the control unit of the MPU 102 into one chip.

  Hereinafter, the configuration in which the separate control unit is used as described above is also referred to as a seventh pattern.

  -Instead of the configurations of the first to seventh patterns described above, even if a configuration is employed in which the action of specifying the timing at which processing related to input and output is executed in the MPU 102 by unauthorized acquisition of a signal is directly suppressed Good. Specifically, a fourth signal path LN4 (see FIG. 11) for electrically connecting the MPU 102 and the first port driver 101a, and a fifth signal for electrically connecting the MPU 102 and the second port driver 101b. Even though it is the timing when the process of receiving the signal in the MPU 102 is not actually executed on the path LN5, the corresponding signal is transmitted, and the signal of the signal received in the MPU 102 is transmitted when the dummy signal is transmitted. May not be confirmed or invalidated. In this case, the signal may be periodically transmitted, or may be irregularly transmitted. Further, the signal may be transmitted from a dedicated element provided on the path between the MPU 102 and the port drivers 101a and 101b, or may be transmitted by the MPU 102 itself.

  Further, as described above, the target for transmitting the dummy signal is not limited to one or both of the signal path LN4 and the signal path LN5, and additionally or alternatively, the signal path LN1, the signal path LN2 and At least one of the signal paths LN3 may be configured as a target. For example, when attempting to read the presence or absence of execution of processing relating to input / output illegally through the signal path LN1 or the signal path LN2, it is conceivable to read a change in current flowing through the signal paths LN1 and LN2. Therefore, an element may be provided to cause changes in the current flowing through the signal paths LN1 and LN2 periodically or irregularly at a timing different from when the signal is actually received by the MPU 102. .

  Hereinafter, the configuration for directly suppressing unauthorized acquisition of a signal as described above is also referred to as an eighth pattern.

  It is assumed that fraudulent activity using the above-described fraudulent device A is performed by fraudulently reading the processing time between the two processes related to the signal output from the MPU 102 to the external device. Therefore, any of the configurations of the first to eighth patterns may be applied to such a configuration. Specifically, the processing time between the two processes related to the command output from the MPU 102 to another control device (the sound light control device 82, the payout control device 97, the power supply and the emission control device 98) It is assumed that it is used and read illegally. In this case, for example, when the jackpot random number update process or the random number update process for lottery is executed between the process related to one command output and the process related to the next command output, the jackpot random number update process or lottery The configuration of any one of the first to eighth patterns may be adopted for the random number updating process.

  The jackpot random number counter does not adopt any of the configurations of the first to eighth patterns in order to make it difficult or impossible to specify the timing at which the numerical information of the jackpot random number counter C1 becomes the minimum value. In order to make it difficult or impossible to specify the timing at which the numerical value information of C1 is set to the initial value of the new update cycle, any of the configurations of the first to eighth patterns may be adopted.

  For example, when the first pattern or the second pattern is adopted, the processing time in the case where the numerical information of the jackpot random number counter C1 is set to the initial value, and the numerical information of the jackpot random number counter C1 is its numerical value The processing configuration such as processing for time adjustment is set as in the first pattern and the second pattern so that the processing time in the case of sequentially updating toward one boundary of the range becomes the same or substantially the same. do it.

  When the fifth pattern is adopted, the processing time when the numerical information of the jackpot random number counter C1 is set to the initial value, and the numerical value of at least one of the jackpot type counter C2 and the electronic combination random number counter C4. The processing configuration such as the time adjustment processing may be set as in the first pattern or the second pattern so that the processing time when the information is set to the initial value is the same or substantially the same. .

  In addition to adopting any of the configurations of the first to eighth patterns, in order to make it difficult or impossible to specify the timing when the numerical information of the jackpot random number counter C1 becomes the minimum value or the initial value Alternatively, for at least one of the counters used in the processing of granting other benefits, specifically, at least one of the jackpot type counter C2 and the electric random number counter C4, specify the timing when the numerical information becomes the minimum value or the initial value In order to make it difficult or impossible to specify, any of the configurations of the first to eighth patterns may be adopted.

  · The jackpot random number counter C1 is configured to be incremented by one when the numerical information is sequentially updated toward one boundary of the numerical range, but when the numerical information is sequentially updated The numerical value information may be decremented by one. In this case, as a result of subtracting one from the numerical information, the maximum value is set when the value falls below the minimum value. Even in this configuration, when setting the numerical value information below the minimum value to the maximum value, the processing time becomes longer as compared to the case where the numerical information is sequentially updated, so the first to eighth It is preferable to adopt any configuration of the pattern.

  The jackpot random number counter C1 is not limited to a configuration in which numerical values change one by one when numerical information is sequentially updated, and for example, "2" → "4" → "6" → "8" It may be configured to change by two, such as →. Further, it may be configured to change two by two such as “1” → “3” → “5” → “7” →. Further, the amount of change in the numerical value is not limited to “1” or “2”, and may be configured to change by another predetermined amount such as “3” or “4”. Even in these cases, when one boundary is exceeded, it is necessary to set numerical information corresponding to the other boundary, and the processing time for this setting is sequentially updated as described above It is conceivable that the processing time is different. Therefore, even if it is the said structure, it is preferable to employ | adopt the structure in any one of the said 1st-8th pattern.

  The configuration may be such that the setting from one boundary side of the numerical range to the other boundary side is performed multiple times in one update round of the big hit random number counter C1. For example, first, numerical information is sequentially updated as "2" → "4" → "6" → "8" → ... and the maximum value is exceeded, the value is "1" which is the minimum value side. The setting is made, and thereafter, the numerical information is sequentially updated again such as “1” → “3” → “5” → “7” →. Then, when all the numerical information is set once, a new initial value may be set to start a new update cycle. Even in this case, when one of the boundaries is exceeded, it is necessary to set numerical information corresponding to the other boundary, and processing in the case where the processing time for this setting is sequentially updated as described above It is thought that it is different from time. Therefore, even if it is the said structure, it is preferable to employ | adopt the structure in any one of the said 1st-8th pattern.

  The jackpot random number counter C1 is not limited to a configuration in which the same numerical value changes each time the numerical information is sequentially updated, and the predetermined update timing may be selected in the case where the numerical information is sequentially updated. While changing by one predetermined number, it may be configured to change by a second predetermined number different from the first predetermined number at other update timings. However, the numerical value information is sequentially updated according to a predetermined order. Even in this case, when one of the boundaries is exceeded, it is necessary to set the numerical information corresponding to the other boundary, and the processing time in this setting is sequentially updated as described above It is thought that it is different from time. Therefore, even if it is the said structure, it is preferable to employ | adopt the structure in any one of the said 1st-8th pattern.

  -Other types of pachinko machines and the like different from the above embodiment, for example, pachinko machines in which the motorized part opens a predetermined number of times when gaming balls enter a specific area of a special device, or gaming balls enter a specific area of a special device The present invention can also be applied to gaming machines such as a pachinko machine which becomes a jackpot and a pachinko machine provided with other features, an arrange ball machine, and a ball ball, etc.

  A non-ball-ball type game machine, for example, a plurality of reels having a plurality of kinds of symbols attached in the circumferential direction, starts the rotation of the reels by inserting medals and operating the start lever, and the stop switch is operated. If a specific symbol or a combination of specific symbols is established on an effective line visible from the display window after the reel is stopped by the passage of a predetermined time, a bonus such as payout of medals is awarded to the player The present invention can also be applied to slot machines.

  In addition, the gaming machine main body supported in an openable and closable manner by the outer frame is provided with the storage section and the loading device, and the start lever is operated after the predetermined number of gaming balls stored in the storage section are loaded by the loading device. The present invention can also be applied to a gaming machine in which a pachinko machine and a slot machine are integrated by starting to rotate the reels.

  When applied to a slot machine or applied to a gaming machine in which a pachinko machine and a slot machine are integrated, the main control unit updates the numerical information of the lottery counter used to execute the winning or not of the winning combination, The configuration of any one of the first pattern to the eighth pattern may be adopted, and a bonus to the player (specifically, a sub control device that controls the display device based on an instruction from the main control device). With regard to updating of the numerical information of the lottery counter used to execute the lottery that affects the awarding rate of the medal payout), any configuration of the first pattern to the eighth pattern may be adopted. Good.

Second Embodiment
The act of illegally reading that the numerical information storage means such as the jackpot random number counter C1 is the predetermined numerical information is the unauthorized device A (see FIG. 11) for each of the fourth signal path LN4 and the fifth signal path LN5. Other than the action performed based on electrically connecting the fourth signal path LN4 or the fifth signal path LN5 with the electromagnetic wave noise accompanying the signal transmission (that is, the specific electric path the predetermined current (the first current) Acts (hereinafter referred to as cheating by the act as specific cheating) based on the picking up of electromagnetic wave noise accompanying the flow of

  Specifically describing the specific fraud, first, on the back side of the pachinko machine 10, a fraudulent jig provided with a detection unit for detecting electromagnetic wave noise at the tip of a long member such as a cell is provided. insert. In this insertion, a slight gap is generated between the lower end portion of the game machine body 12 and the lower frame portion of the outer frame 11 by pushing the game machine body 12 upward, and the line is used by utilizing the gap. It will be. And while operating the inserted incorrect jig so that the tip part reaches the back side of the pachinko machine 10, it reaches the main control device 81 side which exists above the lower end part of the gaming machine main body 12 To operate. After leading the tip of the incorrect jig to the main controller 81, the tip of the incorrect jig is disposed at a position behind the pachinko machine 10 with respect to the area where the MPU 102 is provided in the main controller 81. .

  In this state, the electromagnetic wave noise in the case where the signal output is performed through the fourth signal path LN4 is detected by the incorrect jig, whereby the power failure information storage process (step S201) in the timer interrupt process (FIG. 9). The execution stop can be determined in the timer interrupt process (FIG. 9) by detecting the electromagnetic wave noise when the signal output is performed through the fifth signal path LN5 with an unauthorized jig while being able to grasp the execution timing illegally. The execution timing of (step S205) can be illegally grasped. Then, by reading the time between these processes, it becomes possible to grasp the time required for the lottery random number update process (step S202) in the timer interrupt process (FIG. 9).

  The above-mentioned specific fraud can be suppressed by the configuration of the fraud countermeasure shown in the first embodiment. However, in the present embodiment, the configuration of the fraud countermeasure is different from that of the first embodiment. Hereinafter, the configuration of the fraud countermeasure will be described. The same reference numerals as in the first embodiment denote the same parts as those in the first embodiment, and a description thereof will be basically omitted.

  FIG. 22 is a rear view of the gaming machine main body 12 in the present embodiment. FIG. 23 (a) is a perspective view of the gaming machine main body 12 viewed from the rear side, and FIG. 23 (b) is an exploded perspective view showing a state in which the countermeasure against fraud is removed in the state of FIG. 23 (a). FIG. In addition, in FIG. 23 (a) and FIG.23 (b), the state which removed the front door frame 14 is shown.

  As shown in FIGS. 22 and 23 (a) and 23 (b), the main control unit 81 is provided on the back side of the inner frame 13 (game board 24) as in the first embodiment. . In this case, the main control device 81 is in the form of a substantially rectangular box having a rectangular front surface and a rear surface, and the front surface of the main control device 81 faces the back of the pachinko machine 10 and the rectangular long side portion It is being fixed to the inner frame 13 so that a direction may turn into a horizontal direction. Further, the position at which the main control device 81 is disposed is below the longitudinal center of the pachinko machine 10 and above the lower end portion of the gaming machine main body 12.

  As in the first embodiment, the main control device 81 includes a main control substrate 101 and a substrate box 83 for housing the main control substrate 101. The substrate box 83 is transparent, specifically, colorless and transparent so that the main control substrate 101 can be seen from the outside of the substrate box 83. As shown in FIG. 22, the MPU 102 is mounted on the main control board 101, and the main control board 101 is electrically connected to the payout control device 97, the power supply and emission control device 98, and various sensors. Connectors 121a to 121e are provided as connection parts of The connectors 121 a to 121 e are exposed to the outside of the main control device 81 through openings 122 a to 122 e formed in portions of the substrate box 83 that constitute the surface of the main control device 81. Further, the main control device 81 is provided with an initialization switch 123 which is operated when the initialization of the RWM 104 is performed, and the initialization switch 123 also constitutes the surface of the main control device 81 in the substrate box 83. The main control unit 81 is exposed to the outside through an opening 124 formed in the portion where

  The substrate box 83 is provided with a trace means for leaving a trace when the internal space is opened. As one of the trace means, a sealing seal 125 is attached so as to straddle between a plurality of case bodies constituting the substrate box 83. In order to open the internal space of the substrate box 83, the plurality of case bodies need to be separated, and in the case of the separation, the sealing seal 125 needs to be peeled off. When the sealing seal 125 is peeled off from the pasting point, the adhesive layer of the sealing seal 125 remains on the substrate box 83 side, and the trace thereof remains.

  In addition, the seal seal 125 is provided with an IC tag for transmitting a response wave including identification information to a call wave transmitted from a reader device held by a game hall manager. This IC tag is provided so that when the seal seal 125 is peeled off, the antenna of the IC tag is cut off and transmission of the response wave becomes impossible. Therefore, it is possible to easily check whether or not the substrate box 83 has been illegally opened by transmitting a calling wave from the reader device in a state in which the gaming machine main body 12 is rotated forward with respect to the outer frame 11. It becomes possible. The sealing seal 125 is provided at one short side of the substrate box 83, and is present at one lateral end of the main controller 81 when the main controller 81 is mounted on the pachinko machine 10 doing.

  A back pack unit 15 is rotatably supported on the back side of the inner frame 13 on which the main control device 81 is mounted. The back pack unit 15 includes a back pack 91 that covers the back surface side of the inner frame 13. The back pack 91 is bulged rearward of the pachinko machine 10, and a protective cover portion 94 is integrally formed. The protective cover 94 covers the game board 24 of the inner frame 13 from the rear in the closed state of the back pack unit 15. However, as shown in FIG. 23 (b), the main controller 81 does not cover the whole, but only a part of it. Specifically, the upper edge of the main controller 81 is It covers only the part and one side edge.

  The one side edge is the side where the sealing seal 125 is not provided. Therefore, the seal seal 125 is not covered by the back pack unit 15, and the seal is made when the gaming machine body 12 is rotated forward with respect to the outer frame 11 to expose the back side of the gaming machine body 12. The reader device can be easily brought closer to the seal 125 side.

  As shown in FIG. 22, a part of the plurality of connectors 121a to 121e is provided on the upper edge of the main controller 81 covered by the protective cover portion 94, but these connectors 121a to 121c An electric connection between an apparatus such as the magnet detection sensor 109 provided on the side of the game board 24 and the main control board 101 is performed. Therefore, the work for making the electrical connection is basically performed in a state where the back pack unit 15 is opened, and there is a problem even if the connectors 121a to 121c are covered by the protective cover portion 94. It does not occur.

  On the other hand, at the lower edge portion of the main control device 81, the rest of the plurality of connectors 121a to 121e are provided. The connectors 121 d and 121 e are provided to electrically connect the main control board 101 with devices provided on the back pack unit 15 side such as the payout control device 97 and the power supply and discharge control device 98. . Therefore, by not covering these connectors 121d and 121e with the protective cover portion 94, even when the back pack unit 15 is in a closed state, the wiring connection to the connectors 121d and 121e can be easily performed. It becomes possible. Further, the area not covered by the protective cover portion 94 in the main control device 81 includes the rear area of the MPU 102.

  Incidentally, the protective cover portion 94 is formed transparent, specifically colorless and transparent so that the area covered by the protective cover portion 94 can be seen from the outside when the back pack unit 15 is closed. There is. Therefore, even if the upper edge portion or the like of main controller 81 is covered by protective cover portion 94 as described above, it becomes possible to visually observe the covered region with back pack unit 15 closed. .

  As shown in FIGS. 22 and 23A, the protective cover 94 is formed with a large number of heat dissipation holes 94a so as to penetrate the protective cover 94 inside and outside. The shield plate 130 is provided so as to be hooked to the heat dissipation hole 94 a on the lower end side among the large number of heat dissipation holes 94 a and supported by the protective cover portion 94. The said shield board 130 is demonstrated in detail below, also referring FIG. 24 (a)-(c).

  As shown in FIG. 24A, the shield plate 130 is formed by sticking a noise suppression sheet 132 to a base portion 131 which determines the shape of the shield plate 130. The base portion 131 and the noise suppression sheet 132 are transparent, specifically colorless and transparent, so that the area covered by the shield plate 130, that is, the main control device 81 and the inside thereof can be seen in the state where the shield plate 130 is attached. Is formed. Moreover, the noise suppression sheet | seat 132 suppresses that the said electromagnetic wave noise permeate | transmits and reflects the noise suppression sheet | seat 132 by converting electromagnetic wave noise into heat.

  As shown in FIGS. 24B and 24C, the shield plate 130 is identical to the plate-like portion 133 overlapping the surface of the main control device 81 from the rear of the pachinko machine 10 and the peripheral portion of the plate-like portion 133. A plurality of upstanding wall portions 134a and 134b, which are formed to stand up in the direction, and a hook portion 135 for hooking on the heat dissipation hole 94a are integrally formed. The hook portions 135 are provided at the upper edge of the plate-like portion 133 so as to form a left-right pair, and as shown in FIG. 22, the pair of hook portions 135 are formed on the lower edge side of the protective cover 94. The heat radiation hole 94a is hooked and supported.

  Although the description by the illustration is omitted, the shield plate 130 is fixed to the protective cover 94 using not only the hook portion 135 but also the double-sided tape, but it is optional whether the double-sided tape is fixed or not. It is. Further, the shield plate 130 may be fixed to the protective cover portion 94 by using a fixing tool such as a screw, or may be fixed by using an adhesive.

  However, the shield plate 130 is not fixed to the main control device 81, and is not fixed to the inner frame 13 and the game board 24 side. As a result, when rotating the back pack unit 15 with respect to the inner frame 13, there is no need to remove the shield plate 130, so that the back pack unit 15 needs to be rotated at the time of maintenance of the main control device 81. Work efficiency does not decrease.

  As described above, in the state where the shield plate 130 is supported, the plate-like portion 133 is in a region (hereinafter also referred to as a lower region 94 b) below the heat dissipation holes 94 a of the hooking target in the protective cover portion 94. On the other hand, the pachinko machine 10 overlaps from the rear of the pachinko machine 10, and overlaps the area of the surface of the main controller 81 not covered by the protective cover portion 94 from the rear of the pachinko machine 10. That is, the shield plate 130 is provided so as to extend the range covered by the protective cover portion 94 from the rear to substantially the entire main control device 81.

  The shield plate 130 overlaps the lower area 94b of the protective cover 94 from the rear of the pachinko machine 10 as described above, and the extension area 94c overlaps the side edge of the main controller 81 in the protective cover 94. Also against the pachinko machine 10 from behind. The adhesive fixing with the double-sided adhesive tape is performed on the lower area 94 b and the extension area 94 c. Therefore, it is difficult to insert an incorrect jig into the main control device 81 through the boundary between the lower area 94b and the shield plate 130 and the boundary between the extension area 94c and the shield plate 130. .

  Further, on the back surface of the plate-like portion 133, a ridge portion 136 which rises up toward the main control device 81 and extends along the long side of the main control device 81 is integrally formed. As shown in FIG. 23 (b), the main control device 81 is formed with a step surface 126 such that the upper end side is recessed toward the back side on the front surface, and the ridge 136 from above the step surface 126 is formed. It is in the state of contact. As a result, the weight load of the shield plate 130 is also received by the main controller 81, and the shield plate 130 can be supported in a stable state.

  MPU 102 and its periphery (first port driver 101a, second port driver 101b, third signal path LN3, fourth signal) in the area where shield plate 130 overlaps on the surface of main controller 81 on the surface of substrate box 83 An area facing the path LN4 and the area where the fifth signal path LN5 is provided) is included. Therefore, the MPU 102 and its periphery are covered not only by the substrate box 83 but also by the shield plate 130. In this case, the noise suppression sheet 132 is provided at least for the opposing region so as to constitute the surface of the shield plate 130. More specifically, the noise suppression sheet 132 is provided on the entire surface or substantially the entire surface of the shield plate 130. The noise suppression sheet 132 is formed so as to make it impossible to transmit an electromagnetic wave generated as a result of the signal output from the MPU 102. As a result, even if the illegal jig is inserted and the tip end portion thereof is disposed at the rear of the shield plate 130, it becomes possible to disable the detection of noise accompanying the signal output from the MPU 102.

  A plate-like portion 133 is provided on the shield plate 130 so as not to cover the payout control device 97 in the main control device 81, the connectors 121d and 121e for electrically connecting the power supply and the emission control device 98, and the initialization switch 123. Are penetrated to form a plurality of exposed holes 137a to 137c. These exposed hole portions 137a to 137c are formed in one-to-one correspondence with the connectors 121d and 121e and the initialization switch 123, and narrowing of the exposed area is achieved. As shown in FIGS. 24 (b) and 24 (c), some of the exposed hole portions 137a to 137c are formed as through holes separated from the peripheral portion of the plate-like portion 133, and the rest A portion of the recess is formed as a recess recessed from the peripheral edge of the plate-like portion 133.

  As shown in FIGS. 23 (a) and 23 (b), the standing wall portions 134a and 134b formed on the shield plate 130 have a side surface not covered by the protective cover portion 94 in the main control device 81, and It forms so that a lower surface may be covered from the outside, respectively.

  In the case of the front side of the substrate box 83, a rising wall portion 134a is formed so as to cover the side surface of the bulging portion that bulges to the front side. As a result, even if an illegal jig is to be inserted between the shield plate 130 and the main controller 81 from the side of the main controller 81 not covered by the protective cover portion 94, it becomes difficult to do so. However, the sealing seal 125 is not covered by the side upright wall portion 134 a, that is, the shield plate 130. This makes it possible to prevent the shield plate 130 from disturbing the operation of reading identification information from the IC tag of the seal seal 125 using the reader device.

  With respect to the coating of the lower surface, the rising wall portion 134b for the lower surface is formed by the formation of a part of the exposed holes 137a and 137b so as to be recessed from the peripheral portion of the plate-like portion 133 as described above. Is formed intermittently. Since the lower wall upright wall portion 134b is formed, even if an illegal jig is inserted between the shield plate 130 and the main controller 81 from the lower surface side of the main controller 81, it becomes difficult to do so. In particular, as described above, since the illegal jig is inserted from the lower end side of the gaming machine main body 12 and the tip of the illegal jig is guided upward to the main controller 81, the lower surface of the main controller 81 It is easy for the tip of the illegal jig to reach the On the other hand, the rising wall portion 134 b is formed so as to cover the lower surface, so that the tip end of the incorrect jig that has reached the lower surface of the main control device 81 further includes the main control device 81 and the shield plate 130. It is suppressed that it gets in between.

  In addition, although the upstanding wall portion 134b for the lower surface is intermittently formed as described above in relation to the exposed hole portions 137a and 137b, the exposed hole portions 137a and 137b are used as the payout control device 97, the power supply, and the emission control. It is provided to connectors 121 d and 121 e for the main controller 81 to make an electrical connection with the device 98. And since the payout control device 97 and the power supply and discharge control device 98 exist below the main control device 81, the wires connected to the connectors 121d and 121e are directed downward based on the connectors 121d and 121e. It extends. Therefore, even if the upstanding wall portion 134b for the lower surface is intermittently formed, the interrupted portion is substantially covered by the wiring, and the main controller 81 and the main control device 81 are utilized by using the interrupted portion. Even when trying to insert an incorrect jig between the shield plate 130, it is difficult to do so.

  In the present embodiment, the processing configurations of the first to eighth patterns described in the first embodiment are not provided, but the processing configuration of any of the first to eighth patterns is described. May be provided.

  According to the present embodiment described above, since the shield plate 130 is provided to cover the main control device 81 from the rear of the pachinko machine 10, a fraudster performs a lottery in the timer interrupt process (FIG. 9). Even if an illegal jig is inserted behind the pachinko machine 10 of the main control unit 81 to detect the noise associated with the signal output from the MPU 102 in order to illegally grasp the time required for the random number update process (step S202), Can be disabled.

  By the way, according to the above configuration in which the shield plate 130 is provided, the electromagnetic wave noise accompanying the signal output from the MPU 102 is detected, and the processing time and processing timing other than the time required for the random number update process for drawing Acts can also make it impossible. Further, by giving electromagnetic wave noise to the MPU 102 from the outside of the main control device 81, it is possible to cope with an action to obtain an illegal privilege by causing abnormality in the operation of the MPU 102.

  In the shield plate 130, exposed holes 137a to 137c are formed so as to expose the connectors 121d and 121e and the initialization switch 123. As a result, it is possible to suppress such fraudulent acts while facilitating the electrical connection work of the wires to the connectors 121 d and 121 e and the operation of the initialization switch 123.

  Further, since the respective exposure holes 137a to 137c are formed in one-to-one correspondence with the portions to be exposed, it is possible to make the area exposed in the main control device 81 as narrow as possible. As a result, even if it is attempted to insert the tip portion of the incorrect jig between the shield plate 130 and the main control device 81 using the exposed hole portions 137a to 137c, it becomes difficult to do so.

  In addition, it is not limited to the description content of embodiment mentioned above, A various deformation | transformation improvement is possible within the range which does not deviate from the meaning of this invention. For example, it may be changed as follows. Incidentally, the configuration of the other embodiment described below may be applied individually to the configuration of the above embodiment, or may be applied in combination.

  The shield plate 130 or the noise suppression sheet 132 may be provided not only on the front surface side of the main control device 81 but also on the rear surface side. For example, in addition to the surface side of the main controller 81, the shield plate 130 or the noise suppression sheet 132 may be provided to a mount for installing the main controller 81. The shield plate 130 or the noise suppression sheet 132 may be provided on the back surface.

  The shield plate 130 or the noise suppression sheet 132 may be directly attached to the substrate box 83. For example, the shield plate 130 or the noise suppression sheet 132 may be attached to the inner peripheral surface for defining the internal space of the substrate box 83.

  In the configuration in which the cover portion individually surrounding the MPU 102 is provided in the internal space partitioned by the substrate box 83, the shield plate 130 or the noise suppression sheet 132 may be attached to the cover portion. Good. That is, the shield plate 130 or the noise suppression sheet 132 may be attached only to a region facing the MPU 102 in the substrate box 83, not substantially the entire surface of the substrate box 83.

  The substrate box 83 itself may be configured to suppress transmission of electromagnetic wave noise by including a material that suppresses transmission of electromagnetic waves to the material forming the substrate box 83.

  The shield plate 130 may be integrally formed with the protective cover 94. Further, the protective cover portion 94 may be provided so as to also cover the rear of the pachinko machine 10 of the main control device 81, and the noise suppression sheet 132 may be attached to the area covered from the rear.

  · In the MPU 102 having a rectangular shape in a plan view, one of the fourth signal path LN4 and the fifth signal path LN5 (that is, one signal path to be subjected to noise detection) extends from one side of the MPU 102, and the other (that is, noise detection) The other signal path to be processed may be extended from the other side of the MPU 102, preferably from the other side. In this case, a plurality of fraudulent jigs for detecting noise is required instead of one, and it becomes difficult to conduct fraudulent acts. In addition, it is preferable that the distance between the two signal paths be set closer to the downstream side than the distance at the connection portion on the MPU 102 side with respect to the MPU 102. If the MPU 102 is rectangular in plan view, it is preferable that one signal path extend from one short side and the other signal path extend from the opposite short side.

  In addition to or instead of the configuration in which the shield plate 130 or the noise suppression sheet 132 is provided as described above, the configuration of the eighth pattern in the first embodiment may be applied.

  -Other types of pachinko machines and the like different from the second embodiment, for example, pachinko machines in which a motorized jack opens a predetermined number of times when game balls enter a specific area of a special device, or a special area of a special area The present invention can be applied to a pachinko machine that becomes a jackpot when a ball enters and becomes a jackpot, a pachinko machine equipped with other features, an arrange ball machine, a game machine such as a ball ball, etc.

  A non-ball-ball type game machine, for example, a plurality of reels having a plurality of kinds of symbols attached in the circumferential direction, starts the rotation of the reels by inserting medals and operating the start lever, and the stop switch is operated. If a specific symbol or a combination of specific symbols is established on an effective line visible from the display window after the reel is stopped by the passage of a predetermined time, a bonus such as payout of medals is awarded to the player The present invention can also be applied to slot machines.

  In addition, the gaming machine main body supported in an openable and closable manner by the outer frame is provided with the storage section and the loading device, and the start lever is operated after the predetermined number of gaming balls stored in the storage section are loaded by the loading device. The present invention can also be applied to a gaming machine in which a pachinko machine and a slot machine are integrated by starting to rotate the reels.

Third Embodiment
The present embodiment is different from the first embodiment in the configuration of the countermeasure against the injustice for specifying the numerical information of the big hit random number counter C1 by acquiring the specific injustice, that is, the electromagnetic wave noise. Hereinafter, the configuration of the fraud countermeasure will be described. The same reference numerals as in the first embodiment denote the same parts as those in the first embodiment, and a description thereof will be basically omitted.

  FIG. 25 is a circuit diagram of the mounting surface side of the main control board 101 in the present embodiment. Here, arrows in FIG. 25 indicate wiring patterns.

  As shown in FIG. 25, on the main control board 101, an MPU 102 and a clock circuit 201 for outputting a clock signal of nsec cycle to the MPU 102 are mounted. The clock circuit 201 is electrically connected to the MPU 102 through the sixth signal path LN6. The clock signal output from the clock circuit 201 is input to the MPU 102. And MPU102 performs various processes, such as timer interruption processing, based on a clock signal.

  The clock circuit 201 and the sixth signal path LN6 are similarly mounted in the first and second embodiments. Here, the clock circuit 201 is provided separately from the clock circuit and the divider circuit for outputting a pulse signal for specifying the start timing of the timer interrupt processing described above by the MPU 102, but the present invention is not limited thereto. For example, one clock circuit 201 may be shared. That is, two paths connecting the clock circuit 201 and the MPU 102 may be provided, and a divider circuit may be provided in one path for dividing the clock signal output from the clock circuit 201 into a clock signal of 4 msec cycle. .

  The MPU 102 includes an input / output port 102 b that outputs a clock signal. A seventh signal path LN7 for transmitting a clock signal or a signal corresponding thereto is connected to the input / output port 102b. The MPU 102 performs various processing such as timer interrupt processing using the clock signal input from the clock circuit 201, and outputs the clock signal to the outside through the input / output port 102b. Then, the clock signal is transmitted to the main control board 101 through the seventh signal path LN7.

  Here, the seventh signal path LN7 will be described in detail. The seventh signal path LN7 is formed on the same plane as the plane on which the signal paths LN4 and LN5 are formed in the main control substrate 101. The surface on which the signal paths LN4, LN5, and LN7 are formed is a mounting surface on which the MPU 102 is mounted. The main control device 81 is attached with the mounting surface facing rearward so that the mounting surface can be viewed from the rear.

  The seventh signal path LN7 is attached to the main control board 101 in a state where one end is connected to the input / output port 102b and the other end is not electrically connected to any of them, that is, in a floating state. .

  The seventh signal path LN7 is formed to go around the edge of the main control substrate 101 formed in a rectangular shape. Specifically, the seventh signal path LN7 includes longitudinal paths LN7a and LN7b extending in the longitudinal direction of the main control substrate 101, and short paths LN7c and LN7d extending in the lateral direction of the main control substrate 101. . As each of these paths LN7a to LN7d continues, the seventh signal path LN7 makes one turn around the edge of the main control board 101. In this case, the signal paths LN4 and LN5 are formed in the region surrounded by the seventh signal path LN7.

  Further, a part of the seventh signal path LN7 and a part of the fourth signal path LN4 and the fifth signal path LN5 which are targets of acquisition of electromagnetic waves by the unauthorized device A are formed to run in parallel.

  Specifically, the MPU 102 and the first port driver 101 a are disposed at predetermined intervals in the longitudinal direction of the main control board 101. The fourth signal path LN4 connecting the two has a longitudinal path LN4a extending in the longitudinal direction of the main control substrate 101. The longitudinal path LN4a is formed longer than the path along the short direction in the fourth signal path LN4. The longitudinal path LN4a runs parallel to the inside of the longitudinal path LN7a in the seventh signal path LN7.

  Furthermore, the second port driver 101b is disposed at a predetermined distance in the lateral direction with respect to the first port driver 101a. That is, the second port driver 101 b is disposed at a position diagonally separated from the MPU 102. The fifth signal path LN5 connecting the two includes a longitudinal path LN5a extending in the longitudinal direction of the main control substrate 101 and a short path LN5b extending in the lateral direction of the main control board 101. The longitudinal path LN5a of the fifth signal path LN5 runs parallel to the inside of the longitudinal path LN7b of the seventh signal path LN7, and the short path LN5b of the fifth signal path LN5 runs inside the short path LN7d of the seventh signal path LN7. I run parallel.

  According to this configuration, when the clock signal is output from the input / output port 102b, the clock signal is transmitted through the seventh signal path LN7. As a result, a predetermined current (corresponding to the second current) corresponding to the clock signal flows through the seventh signal path LN7, and an electromagnetic wave noise (hereinafter referred to as clock noise) corresponding to the clock signal is output. Therefore, the electromagnetic wave noise generated when the signal output is performed through the fourth signal path LN4 or the fifth signal path LN5 and the clock noise are mixed, which makes it difficult to specify the electromagnetic wave noise. Therefore, it is possible to make it difficult to specify the execution timing of the power failure information storage process (step S201) and the execution timing of the game stop determination process (step S205), and specify the time required for the lottery random number update process (step S202) Can be difficult.

  Here, in the case of generating clock noise, it is assumed that the clock noise is mixed in each of the signal paths LN3 to LN5 and a malfunction occurs in the MPU 102. On the other hand, noise removing circuits 211 to 213 for removing the clock noise are provided on the signal paths LN3 to LN5, respectively.

  Each of the noise removal circuits 211 to 213 has the same configuration, and includes a low pass filter circuit that removes noise of at least the frequency of the clock signal. The low pass filter circuit is, for example, an integration circuit, although it is optional. According to this configuration, even when clock noise is generated from the seventh signal path LN7, the clock noise is unlikely to affect the signal paths LN3 to LN5. As a result, it is possible to suppress the malfunction of the MPU 102 caused by the clock noise.

  A frequency change circuit 221 is provided on the seventh signal path LN7 to change the frequency of the clock signal. The frequency changing circuit 221 is configured to change the frequency of the clock signal output from the input / output port 102b and to be able to output the changed clock signal. Thus, a clock signal having a frequency different from that of the clock signal used by the MPU 102 can be output.

  Note that the detailed configuration of the frequency changing circuit 221 will be described. The frequency changing circuit 221 includes a plurality of types of frequency dividing circuits 221 a to 221 c that divide the frequency of the input clock signal. The divider circuits 221a to 221c divide the frequency of the clock signal output from the input / output port 102b (clock circuit 201) into 1 / N (N: natural number of 2 or more). In this case, the division ratio (N) of each of the divider circuits 221a to 221c is different. Specifically, the division ratio of the first divider circuit 221a is 2, the division ratio of the second divider circuit 221b is 8, and the division ratio of the third divider circuit 221c is 16.

  In the following description, the frequency of the clock signal output from input / output port 102b (clock circuit 201) is divided by a predetermined frequency f0 and the frequency of the modified clock signal divided by first divider circuit 221a by a first The peripheral frequency f1 and the frequency of the modified clock signal divided by the second divider circuit 221b are divided by a second divider frequency f2 and the frequency of the modified clock signal divided by the third divider circuit 221c is divided by a third The circumferential frequency is f3.

  The frequency change circuit 221 is connected to the MPU 102. The MPU 102 outputs a change signal to the frequency change circuit 221 when the predetermined change timing is reached. The frequency change circuit 221 selects one of the frequency division circuits 221 a to 221 c based on the change signal from the MPU 102. Then, the frequency change circuit 221 divides the clock signal output from the input / output port 102b by the division ratio of the selected division circuit using the selected division circuit, and divides the clock signal. The received clock signal is transmitted to the seventh signal path LN7 as a modified clock signal. As a result, the modified clock signal having a frequency different from that of the clock signal output from the clock circuit 201 transmits the seventh signal path LN7, thereby generating clock noise having a frequency different from that of the clock signal output from the clock circuit 201. Do. Therefore, the clock noise can be removed to prevent the fraudulent act of acquiring only the desired electromagnetic wave noise.

  That is, when the electromagnetic wave noise to be acquired and the clock noise are mixed, it is assumed that only the clock noise is removed from the noise acquired by the unauthorized device A and only the electromagnetic wave noise is acquired. Ru. In this case, in a configuration in which clock signals of the same cycle are output, identification of clock noise and removal thereof can be easily performed.

  On the other hand, specifying the clock noise can be made difficult by providing the frequency changing circuit 221 as described above and making the frequency of the clock noise variable. As a result, it is possible to suppress only the clock noise and to suppress the fraudulent act of extracting only the target electromagnetic wave noise.

  The number of types of frequencies that can be changed is arbitrary as long as it is plural. For example, two types of divider circuits may be provided, or four or more types may be provided.

  Further, the specific configuration of the frequency changing circuit 221 is arbitrary as long as the frequency can be changed. For example, an oscillator circuit that outputs a clock signal of a predetermined frequency, the clock signal, and a clock signal output from the input / output port 102b are mixed to generate a clock signal of one frequency corresponding to the frequency of both of them. And a mixer circuit.

  Here, the noise removing circuits 211 to 213 are configured to be able to remove the clock signals of the plurality of types of frequencies in response to the clock signal of the plurality of types of frequencies being output by the frequency changing circuit 221. It is done. Specifically, each of the integration circuits of the noise removal circuits 211 to 213 includes a plurality of (specifically, four) series connected bodies each including a capacitor and a switching element (for example, MOSFET). Each series connection body is connected in parallel with each other and in series with a prescribed resistance. The capacitance of the capacitors in each series connection is different. According to this configuration, the overall electrostatic capacitance in the integration circuit changes in response to the switching element being turned on / off. This changes the frequency range to be blocked (removed).

  In this case, the capacitance of the capacitors of each series connection is set such that the frequency of the modified clock signal divided by each of the dividing circuits 221a to 221c is included in the cutoff frequency band.

  Specifically, in the integration circuit, a predetermined frequency f0, which is the frequency of the clock signal output from the input / output port 102b, includes the above-mentioned prescribed resistance and the 0th capacitor of the 0th series connected body among the respective series connected bodies. The capacitance of the zeroth capacitor is set to be included in the cutoff frequency band.

  A first division frequency f1 which is the frequency of the modified clock signal divided by the first division circuit 221a is an integral formed of the above-mentioned prescribed resistance and the first capacitor of the first series connected body among the respective series connected bodies. The capacitance of the first capacitor is set to be included in the cutoff frequency band of the circuit.

  A second division frequency f2 which is the frequency of the modified clock signal divided by the second division circuit 221b is an integral formed of the above-mentioned prescribed resistance and the second capacitor of the second series connected body among the respective series connected bodies. The capacitance of the second capacitor is set to be included in the cutoff frequency band of the circuit.

  The third division frequency f3 which is the frequency of the modified clock signal divided by the third division circuit 221c is an integral formed of the above-mentioned prescribed resistance and the third capacitor of the third series connected body among the respective series connected bodies. The capacitance of the third capacitor is set to be included in the cutoff frequency band of the circuit.

  With the above configuration, by performing ON / OFF control of the switching elements of each series connection, it is possible to preferably block (remove) clock noise generated based on the modified clock signal.

  As shown in FIG. 25, a change signal for instructing the frequency change circuit 221 to change the frequency is transmitted to each of the noise removal circuits 211 to 213. Each noise removal circuit 211 to 213 turns on / off each switching element of each series connection so that the frequency of the clock signal of the change destination is included in the cutoff frequency band when the change signal is input. Take control. For example, when transmitting the modified clock signal divided by the first divider circuit 221a to the seventh signal path LN7, the switching element of the first series connector is turned ON, and the other switching elements are turned OFF. Thus, clock noise based on the modified clock signal can be suitably removed in each of signal paths LN3 to LN5.

<About noise control processing>
The MPU 102 executes noise control processing for controlling the frequency change circuit 221 and the noise removal circuits 211 to 213. The noise control process is executed after execution of the process of step S221 in the timer interrupt process executed by the MPU 102. The noise control processing will be described using the flowchart of FIG.

  First, in step S1401, it is determined whether it is time to change the frequency. Specifically, it is determined whether the frequency change timer counter stored in the predetermined counter area of the RWM 104 is “0”. The frequency change timer counter is a timer counter for measuring a change interval of the frequency of the change clock signal transmitted through the seventh signal path LN7. The frequency change timer counter is set to a predetermined value each time the frequency changes, and is decremented by one in the timer update process of step S210.

  If it is determined in step S1401 that the frequency change timer counter is not "0", this processing is ended as it is, while if it is determined that the frequency change timer counter is "0", step S1402 Go to and find out the current frequency.

  Thereafter, in step S1403, a process of determining the change destination frequency is executed based on the current frequency. Specifically, the RWM 104 is a table in which the change order of the frequency is set in advance, specifically, for example, the predetermined frequency f0 → the first divided frequency f1 → the second divided frequency f2 → the third divided frequency f3. The table set in order is stored. In step S1403, the next frequency is grasped as the change frequency with respect to the current frequency by referring to the above table. In this case, if the current frequency is the third divided frequency f3, the predetermined frequency f0 is grasped as the change frequency.

  In the subsequent step S1404, processing of outputting a change signal corresponding to the change frequency determined in step S1403 to the frequency change circuit 221 and the noise removal circuits 211 to 213 is executed. The mode of the change signal is arbitrary as long as the change frequency can be identified. For example, a command in which information for specifying the change frequency is set may be output, and a predetermined pulse signal is transmitted. In the configuration, the number of pulse signals may be different according to the change frequency.

  When the frequency change circuit 221 receives the change signal, the frequency change circuit 221 outputs a change clock signal of a change frequency corresponding to the change signal. Further, each noise removal circuit 211 to 213 performs ON / OFF control of each switching element of each series connection so that the change frequency corresponding to the change signal is included in the cutoff frequency when the change signal is received. Do.

  Thereafter, in step S1405, “50” is set as the initial value of the frequency change timer counter, and the present process is terminated. As described above, the timer interrupt process is executed in units of 4 msec, and the frequency change timer counter is decremented by one each time the timer interrupt process is executed, so every 0.2 sec has elapsed. The frequency change timer counter will be "0". The above-mentioned initial value is optional.

  According to the present embodiment described above, the following excellent effects can be obtained.

  The main control board 101 is provided with a seventh signal path LN7 for transmitting the clock signal output from the input / output port 102b. As a result, the electromagnetic wave noise generated when the signal output is performed through the fourth signal path LN4 or the fifth signal path LN5 and the clock noise are mixed, which makes it difficult to specify the electromagnetic wave noise. Therefore, it is possible to make it difficult to specify the execution timing of the power failure information storage process (step S201) and the execution timing of the game stop determination process (step S205), and the time taken for the lottery random number update process (step S202) Can be difficult to identify.

  In particular, the seventh signal path LN7 is formed so as to go around the edge of the main control substrate 101. As a result, clock noise is likely to be mixed regardless of the direction in which the illegitimate jig is brought close to the main control substrate 101. Thus, by adjusting the position of the illegitimate jig, it is possible to suppress a cheating attempt to receive only the electromagnetic wave noise generated from each of the signal paths LN4 and LN5 without receiving the clock noise.

  Further, by forming the signal paths LN4, LN5, LN7 so that the signal paths LN4, LN5 and the seventh signal path LN7 run in parallel, it is attempted to acquire electromagnetic wave noise generated from the signal paths LN4, LN5. Naturally, clock noise is acquired. Thereby, it is possible to more preferably suppress the fraudulent act of acquiring the electromagnetic wave noise generated from each of the signal paths LN4 and LN5.

  Furthermore, since the seventh signal path LN7 is formed on the same surface as each of the signal paths LN4 and LN5, and is formed on the edge side of the main control board 101 than each of the signal paths LN4 and LN5, clock noise is generated in the incorrect jig. Can be made easy to mix.

  The frequency change circuit 221 is provided in the seventh signal path LN7. As a result, since the frequency of the clock noise is changed, it is possible to remove the clock noise and to suppress the fraudulent act of acquiring the electromagnetic wave noise generated from each of the signal paths LN4 and LN5.

  Further, noise removing circuits 211 to 213 for removing the clock signal or the modified clock signal are provided on the signal paths LN3 to LN5. As a result, it is possible to suppress the malfunction of the MPU 102 due to the clock noise mixing in each of the signal paths LN3 to LN5 while suppressing the fraudulent act of acquiring the electromagnetic wave noise generated from each of the signal paths LN4 and LN5.

  In the present embodiment, the signal paths LN4 and LN5 to be acquired by the unauthorized device A are formed on the mounting surface. However, the present invention is not limited thereto. For example, the signal paths LN4 and LN5 are formed on the opposite side. It may be configured to As a result, when the cheating device A is brought close from the outside of the main control device 81, the main control board 101 is interposed between the cheating device A and each of the signal paths LN4 and LN5. It is difficult to acquire the electromagnetic wave noise generated from LN5. Then, in the main control substrate 101, the signal paths LN4 and LN5 are formed on the opposite side of the seventh signal path LN7, so that clock noise is less likely to be mixed in the signal paths LN4 and LN5. As a result, while making it difficult to obtain electromagnetic wave noise generated from each of the signal paths LN4 and LN5, it is possible to suppress a malfunction of the MPU 102 caused by the generation of clock noise.

  Although the noise removing circuits 211 to 213 are provided to remove clock noise in the present embodiment, the present invention is not limited to this. For example, each signal path LN3 to LN5 is wrapped in a noise removing sheet made of a conductor or the like. It is good also as composition. In this case, the noise removal sheet is grounded. In this case, the signal paths LN4 and LN5 are thickened by the amount of the noise removal sheet, and may physically interfere with other signal paths (wirings) mounted on the mounting surface.

  On the other hand, in the configuration in which the signal paths LN4 and LN5 are provided on the side opposite to the mounting surface as described above, the above interference hardly occurs. Further, it is preferable to provide a grounding portion for grounding the main control substrate 101 on the surface opposite to the mounting surface, and to ground the grounding portion and the noise removing sheet. In this case, the main control substrate 101 can be preferably grounded since the surface on the opposite side to the mounting surface can easily secure the area for the ground portion. Then, since the ground portion and the noise removal sheet are on the same plane, the length of the wiring for connecting the two can be shortened, and the noise removal sheet can be suitably grounded.

  In this embodiment, noise is generated using a clock signal output from the clock circuit 201. However, a clock circuit for generating clock noise may be separately provided separately from the clock circuit 201. In this case, a clock signal having a frequency different from that of the clock signal used by the MPU 102 may be output. This makes it difficult to specify the frequency of clock noise.

  In the present embodiment, it is adopted that the predetermined period (0.2 sec) elapses as a trigger to change the frequency, but the invention is not limited to this. For example, when winning in each operation port 33, 34 or the like occurs, The case where the player has won a predetermined specific effect may be set as a change trigger of the frequency. In this case, since the randomness can be given to the change trigger of the frequency, the specification of the frequency can be made more difficult.

  Further, the predetermined period as a trigger for changing the frequency may be changed. Also by this, it is possible to give randomness to the change trigger of the frequency.

  Although the clock noise is generated in the present embodiment, the present invention is not limited to this. The point is that the signal transmitted through the seventh signal path LN7 is arbitrary as long as noise can be generated at a predetermined cycle. For example, an alternating voltage or a sawtooth waveform may be transmitted.

  Also, the period does not have to be single. For example, a pulse signal group may be output at intervals Ta, and a pulse signal group having one unit until the pulse signal is output at intervals Tb different from interval Ta may be output at a predetermined cycle.

  Further, as a signal to be transmitted to the seventh signal path LN7, for example, a signal having no periodicity such as outputting a pulse signal may be adopted only when winning by lottery.

  In the present embodiment, the seventh signal path LN7 is formed only on the edge side of the main control substrate 101 with respect to the fourth signal path LN4 and the fifth signal path LN5, but the present invention is not limited thereto. For example, the seventh signal path LN7 may be formed to sandwich the fourth signal path LN4 and the fifth signal path LN5. In this case, it is assumed that clock noise is more preferably mixed, so it is more preferable to suppress fraudulent attempts to acquire only electromagnetic wave noise output from the fourth signal path LN4 and the fifth signal path LN5. Can.

  Further, according to the present embodiment, the fourth signal path LN4 and the seventh signal path LN7 are configured to run in parallel in the longitudinal direction of the main control board 101, but the present invention is not limited thereto. It may be configured to run in parallel. However, in view of the fact that the electromagnetic wave noise in which the electromagnetic wave noise generated from the fourth signal path LN 4 and the clock noise are mixed is easily obtained when the distance running parallel is large, it is configured as in the present embodiment. preferable.

  According to the present embodiment, the seventh signal path LN7 is formed to go around the edge of the main control substrate 101, but the present invention is not limited to this. For example, the seventh signal path LN7 may be formed concentrically such that the fourth signal path LN4 and the fifth signal path LN5 are included in the range. The point is that the seventh signal path LN7 may be formed so as to surround the fourth signal path LN4, the fifth signal path LN5, and the like in the main control substrate 101. However, in view of the arrangement of the electronic components to be mounted and the expansion of the mounting area, it is preferable that the seventh signal path LN7 be formed so as to make one turn around the edge of the main control substrate 101.

  The seventh signal path LN7 may be formed so as to extend around the edge of the main control substrate 101 a plurality of times. As a result, since the clock noise is synergistically increased, the specification of the electromagnetic wave noise of the fourth signal path LN4 and the like can be made more difficult.

  Further, a path through which the clock signal is transmitted and a path through which the modified clock signal is transmitted may be formed. In this case, since clock noise becomes complicated, removal of clock noise can be suppressed.

  Furthermore, both may be combined, and the combined signal may be transmitted.

  The other end of the seventh signal path LN7 is in a floating state, but is not limited to this. For example, the seventh signal path LN7 may be connected to the ground via a resistor or the like. However, if attention is paid to generating clock noise more preferably, it is better to be set to be floating.

  In the present embodiment, the output cycle of the clock signal output from the clock circuit 201 is in units of n sec, but is not limited to this and may be shorter than the execution cycle of the timer interrupt processing. More specifically, the frequency of the clock signal (changed clock signal) may be set so that one pulse signal of the clock signal is output at least once between step S201 and step S205.

  Although the clock signal is output from the input / output port 102b of the MPU 102 in this embodiment, the present invention is not limited to this. For example, the seventh signal path LN7 may be directly connected to the clock circuit 201. It may be

  Further, in addition to or in place of the configuration for generating clock noise as described above, the shield plate 130 or the noise suppression sheet 132 in the second embodiment may be provided, and the eighth embodiment in the first embodiment. The configuration of the pattern of may be applied.

  Other types of pachinko machines and the like different from the third embodiment, for example, pachinko machines in which a motorized character opens a predetermined number of times when game balls enter a specific area of a special device, or a game ball in a specific area of a special device The present invention can be applied to a pachinko machine that becomes a jackpot when a right enters and becomes a jackpot, a pachinko machine equipped with other features, an arrange ball machine, a game machine such as a ball ball, and the like.

  A non-ball-ball type game machine, for example, a plurality of reels having a plurality of kinds of symbols attached in the circumferential direction, starts the rotation of the reels by inserting medals and operating the start lever, and the stop switch is operated. If a specific symbol or a combination of specific symbols is established on an effective line visible from the display window after the reel is stopped by the passage of a predetermined time, a bonus such as payout of medals is awarded to the player The present invention can also be applied to slot machines.

  In addition, the gaming machine main body supported in an openable and closable manner by the outer frame is provided with the storage section and the loading device, and the start lever is operated after the predetermined number of gaming balls stored in the storage section are loaded by the loading device. The present invention can also be applied to a gaming machine in which a pachinko machine and a slot machine are integrated by starting to rotate the reels.

  According to the feature A3, when the processing time between the first processing timing and the second processing timing is illegally read, the processing mode of the numerical information updating process is the specific updating mode based on it. If you try to identify, it will be difficult to do it. In particular, even if the processing time is illegally read as described above, it is not possible to specify which of the specific update aspect and the sequential update aspect the processing time corresponds to, so the processing time is predetermined. It corresponds to all numerical information included in the numerical range. If it does so, even if it tries to operate progress of a game unfairly using the processing time, it becomes substantially impossible. Therefore, even if it is attempted to illegally manipulate the progress of the game through the reading of the processing time, it becomes difficult to do so.

The specific update aspect is an aspect in which numerical information that becomes the other boundary is set in the numerical information storage unit based on the execution of the boundary setting processing, according to any one of the features A3 to A7. The gaming machine described.

  According to the processing configuration of feature A8, the numerical information is successively updated toward one of the boundaries in the predetermined numerical range, and the other boundary is dealt with when one of the boundaries in the predetermined numerical range is exceeded. While the process of setting the numerical information can be suitably performed, the processing time required for setting the numerical information is considered to be longer in the latter case. In this case, it is assumed that the processing time between the first processing timing and the second processing timing is illegally read and the timing at which the numerical information corresponding to the other boundary is specified is identified. On the other hand, by providing the configuration of the feature A3, it is possible to make it difficult to specify the timing at which the numerical information corresponding to the other boundary is illegally identified.

  According to the feature A9, since the time difference between the first processing time and the second processing time does not exist or can not be distinguished, it is specified from the processing time between the first processing timing and the second processing timing. Even if it is attempted to specify whether it is the update mode or the sequential update mode, it becomes impossible or difficult to perform.

  Feature A10. The adjustment means executes the boundary setting process when the numerical value information update process is completed in the sequential update mode without performing the boundary setting process as a result of the boundary determination process, and as a result of the boundary determination process. By adding a delay time in a situation where the processing is branched according to the determination result of the boundary determination processing with respect to at least one of the case where the numerical information update processing is completed in the specific update mode, The gaming machine according to feature A9, wherein a time difference between the first processing time and the second processing time does not occur or the time difference is reduced.

  According to the feature A10, the above-described excellent effects can be achieved by the relatively simple processing configuration of adding the delay time. Further, according to this configuration, since the adjustment of the processing time is performed on the side where the processing branches in accordance with the determination result by the boundary determination processing, the processing configuration can be simplified in adjusting the processing time. It is possible.

When the boundary setting process is executed as a result of the boundary determination process, the adjustment means changes the data of the program counter by the first data, thereby executing the process of the determination destination of the boundary determination process. When the boundary setting process is not executed as a result of the boundary determination process, the data of the program counter is changed by an amount corresponding to a second data amount larger than that of the first data. The gaming machine according to any one of the features A8 to A10, wherein the time difference is eliminated or reduced while a process of a determination destination of the boundary determination process is executed.

  When the process according to the result of the determination process is performed, the time required to start the process of the determination destination becomes longer as the data amount of the program counter is changed. In this case, according to the feature A11, in the case where the boundary setting process is performed and the case where the boundary setting process is not performed, in view of the fact that the former processing time is longer, as a result of the determination process, the former The amount of data to be changed in the program counter is smaller when the process of is executed than in the latter case. As a result, it is possible to suppress such fraudulent acts while suppressing an increase in the processing time of each processing of the numerical information update processing.

Such a game machine, for example, performs a lottery for losing the game on condition of entering the operation opening, and in the case of winning, a bonus such as opening the big winning opening is given to the player. Here, at the time of the winning lottery, numerical information is acquired from numerical information storage means such as a random number counter which sequentially updates numerical information in a predetermined numerical range, and whether the numerical information corresponds to predetermined numerical information or not It is performed by determining.

Such numerical information is acquired at the timing of entering the operation opening, and is processed as winning if the numerical information is numerical information corresponding to a jackpot (see, for example, Japanese Patent Application Laid-Open No. 2003-245455).

  However, since the numerical information storage means looping as described above periodically changes the numerical information periodically, there is no end to fraud that is intentionally targeted for the numerical information corresponding to the winning.
