6 (B)). At the timing of this detection, the main CPU 531 causes the plurality of numerical values, for example, 0 to 29.
One of the count values of the jackpot lottery counter that counts a total of 300 of 9 is acquired, and a jackpot or a loss is selected based on whether or not the acquired count value is a jackpot value (for example, 7). In addition, at the above detection timing, a plurality of symbols (for example, 0 to 9) are vertically scrolled and displayed at three horizontal positions on the screen of the special symbol display 504, and a symbol corresponding to the lottery result after a predetermined time has elapsed. Is confirmed and displayed. For example, when the lottery result is a big hit, three identical numbers (for example, “777” as shown in FIG. 15) are fixedly displayed, the door-type opening / closing member 505 is opened, and the special winning opening 506 is displayed. Open.

When a game ball is won in the special winning opening 506, a predetermined number (for example, 15) is attached to each winning ball.
The individual prize balls are paid out to the upper tray 507. In addition, the number of winning balls that have won the special winning opening 506 is a predetermined number (for example,
10), or a predetermined time (for example, 30 seconds) has passed since the special winning opening 506 was opened, or if any of the conditions is satisfied, the opening / closing member 505 is closed and the big winning opening is performed. 506 closes. Furthermore, the big prize hole 50

Further, as shown in FIG. 16, a pachinko machine 5
00, a power failure detection circuit 516 for detecting a power failure is provided, and the power failure detection circuit 516 is connected to the main board 530 and the payout control board 540. Main board 53
The main CPU 531 installed in 0 performs a lottery for a big hit or a loss, a round control, and the like. A computer program executed by the main CPU 531 is recorded in the ROM 533, and a RAM 532 stores a game state when the power is cut off, a computer program read from the ROM 533, a control command transmitted from the main CPU 531 to each board, and the like. The sub CPU 541 mounted on the payout control board 540 controls a prize ball payout motor (not shown) in accordance with the prize ball payout command transmitted from the main board 530. A computer program executed by the sub CPU 541 is recorded in the ROM 543.
M542 is the number of unpaid prize balls when the power is cut off, ROM54
The computer program and the like read out from No. 3 are stored.

Here, when the power supply 520 is cut off, a power cutoff signal is output from the power failure detection circuit 516 to the main board 530 and the payout control board 540, and then to the main CPU 531 and the payout control board 540 mounted on the main board 530. The mounted sub CPUs 541 each execute NMI (Non-Maskable Interrupt) processing, and RAMs 532, 5 storing backup data at the time of power shutdown.
Access to each backup area 42 is prohibited. Further, power is supplied to each backup area from the backup capacitor C2, and the storage of each backup data is held. Then, when the power supply 520 returns, the main CPU 531 reproduces the game immediately before the power shutdown based on the backup data stored and held in the backup area of the RAM 532. In addition, the sub CPU 5
41 restarts the payout of prize balls based on the number of unpaid prize balls stored and held in the backup area of the RAM 542.

However, if the power supply is cut off during the test firing at the time of shipment of the pachinko machine or installation of the pachinko machine,
Data about big hits and winnings that occurred during trial shooting are R
Since it is backed up by AM, opening the store in that state causes inconvenience such as starting a game based on the backed up data. So RAM
There has been proposed a method for eliminating the above inconvenience by providing a RAM clear switch 527 for outputting a RAM clear signal for erasing backup data to each RAM.

[0007]

By the way, as a result of subsequent research, when the RAM clear switch 527 is turned on,
It was found that resetting the initial value of the jackpot lottery counter to "0" could be misused. Figure 1
FIG. 7 is an explanatory diagram showing an example of a circuit in which an illegal act has been performed. An illegal board 5 called a hanging board is provided on a line connecting the RAM clear switch 527 and the main board 530.
50 is connected. In this hanging board 550,
When the command transmitted from the transmitter 560 is received, the main board 5
A circuit for transmitting a RAM clear signal to 30 is provided. Here, the count cycle of the jackpot lottery counter is 2
If it is ms, the time required to start counting from “0” and count the jackpot value “7” is 2
ms × 7 = 14 ms. Further, as shown in FIG. 14 (A), the time required for the game ball P to pass through the first type starting opening 502 and be detected by the first type starting opening switch 510, that is, the first type starting opening 502. It is assumed that the time required to flow down the distance L1 from the first type starting opening switch 27a is 0.1 s. Then, the transmitter 5 is 0.086 seconds after the game ball P passes through the first-type starting opening 502.
When the above command is transmitted from the 60 to the hanging board 550,
RAM clear signal is sent from the hanging board 550 to the main board 53.
It is transmitted to 0, the initial value of the count of the jackpot lottery counter is reset to "0", and the count is started from "0". And 14 ms (= 0.1 s−0.086)
When the game ball P is detected by the first type starting opening switch 510 after s), the jackpot lottery counter then counts "7". Therefore, when the command is transmitted from the transmitter 560 to the hanging board 550 aiming at a timing 0.086 seconds after the game ball P passes through the first type starting opening 502, the main CPU 531
The count value is acquired from the jackpot lottery counter that counts the vicinity of the jackpot value of "7", and the probability of a jackpot is extremely high.

Therefore, the present invention has been made to solve the above-mentioned problems, and illegally hits the jackpot by operating the erasing means (RAM clear switch) for erasing the game state stored when the power is cut off. The object is to realize a gaming machine (pachinko machine) that cannot generate

[0009]

Means, Actions and Effects for Solving the Problems In order to achieve the above object, the present invention provides a counter and a game ball shot on a game board which passes through a predetermined area. Detection means for detecting that, a game state storage means for storing the game state when the power supplied to this gaming machine is cut off, and the game ball has passed the predetermined area by this detection means When a count value of the counter is detected when it is detected, a lottery process of lottery based on the acquired count value whether it is a big hit or a loss, and a value which the counter first counts is returned to an initial value. A computer for executing an erasing process for erasing the game state stored in the game state storing means and a security check process when the system is reset. A gaming machine that is provided and is capable of resuming a game based on the game state stored in the game state storage means when the power supply is resumed, and the computer executes the erasing process. When there is an instruction indicating that, the security check process is executed by generating the system reset, and the erasing process is executed after the security check process is completed.

The computer acquires the count value of the counter when the detecting means detects that the game ball has passed through the predetermined area, and draws a big hit or a loss based on the acquired count value. Execute the lottery process. Further, the computer returns the value at the time when the counter starts counting to the initial value, and also executes an erasing process for erasing the game state stored in the game state storage means. Then, when there is an instruction to execute the erasing process, the computer executes the security check process by generating a system reset, and executes the erasing process after the security check process is completed. That is, the computer does not immediately reset the value at the time when the counter starts counting to the initial value when the erase instruction is issued, and does not erase the game state stored in the game state storage means. After executing the security check process by generating a system reset when erase is instructed, the value when the counter starts counting is returned to the initial value, and the game state stored in the game state storage means is changed. to erase. Therefore, the counter starts counting from the initial value by instructing the erasing aiming at the timing when the game ball passes a predetermined area,
Since it is impossible to match the timing of counting the big hit count value with the timing at which the game balls that have passed the predetermined area are detected by the detection means, a big hit can be illegally generated by issuing an erase instruction. There is no fear.

According to a second aspect of the invention, in the gaming machine according to the first aspect, the signal instructing to execute the erasing process is one of the input ports of the computer.
The technical means of being input to the input port for generating the system reset is used.

In other words, when a player generates a signal instructing to execute an erasing process for the purpose of illegally generating a big hit, the signal causes a system reset of the input ports of the computer. Since it is input to the input port, the computer executes the security check process when the system is reset.

According to a third aspect of the invention, in the gaming machine according to the first or second aspect, the time required for the computer to execute the security check process is such that the game ball is in the predetermined area. The technical means is that the time is longer than the time required for the detection by the detection means after passing through.

That is, since the time required to execute the security check process is longer than the time required from the passage of the game ball through the predetermined area to the detection by the detection means, the security check process is performed. Before the game ends, the game ball is detected by the detection means, and the computer acquires the count value of the counter at the time of the detection and ends the lottery. Therefore, by issuing a deletion instruction aiming at the timing at which the game ball passes through the predetermined area, the counter is counted from the initial value, and the timing at which the count value of the big hit is counted and the game ball is detected by the detection means. Since it is not possible to coincide with the timing to be performed, there is no fear that a big hit will be illegally generated by issuing an erasing instruction.

According to the invention described in claim 4, a counter,
Detecting means for detecting that the game ball shot on the game board has passed a predetermined area, and game state storing means for storing the game state when the power supplied to this game machine is cut off, A lottery process for obtaining a count value of the counter when it is detected that the game ball has passed through the predetermined area by the detecting means, and a lottery for lottery or losing based on the obtained count value, A computer that restores the value initially counted by the counter to an initial value, and executes an erasing process for erasing the game state stored in the game state storing means and a security check process when the system is reset. A game in which the game can be restarted based on the game state stored in the game state storage means when the power supply is restarted. A computer program for causing a computer to function, the computer executing the security check process by generating the system reset when there is an instruction to execute the erasing process, A technical means called a computer program for executing the erasing process after the security check process is completed is used.

That is, since the gaming machine according to claim 1 functions by a CPU (computer) provided in a pachinko machine (gaming machine), for example, as described in an embodiment of the invention described later, By storing the computer program in a recording medium such as a ROM and causing the CPU to execute the stored computer program, the gaming machine can be caused to function.

According to a fifth aspect of the invention, a counter and
Detecting means for detecting that the game ball shot on the game board has passed a predetermined area, and game state storing means for storing the game state when the power supplied to this game machine is cut off, A lottery process for obtaining a count value of the counter when it is detected that the game ball has passed through the predetermined area by the detecting means, and a lottery for lottery or losing based on the obtained count value, A computer that restores the value initially counted by the counter to an initial value, and executes an erasing process for erasing the game state stored in the game state storing means and a security check process when the system is reset. A game in which the game can be restarted based on the game state stored in the game state storage means when the power supply is restarted. A computer-readable recording medium having a computer program for causing a computer to function, wherein the security check is performed by generating the system reset when the computer gives an instruction to execute the erasing process. A technical means called a recording medium in which a computer program for executing the process and executing the erasing process after the security check process is completed is recorded is used.

That is, the gaming machine that functions by using a computer is recorded in a recording medium such as a ROM provided in a pachinko machine (gaming machine), for example, as described in the embodiments of the invention described later.

As a result, the inconvenience that the game is restarted occurs. Therefore, it is necessary to delete the backup data before opening the store.
In FIG. 7, the reset generation circuit normally outputs a signal of H level, and the main CPU 112 outputs a system reset instruction signal of normal L level from the output port Pb1. Further, from the reset generation circuit 118,
The L level signal is output to the AND circuit 122. RA
When the power switch 18 is turned on while pressing the M clear switch 10, the 5V DC from the 5V generation circuit 85 becomes the main C
It is supplied to the PU 112 and the reset generation circuit 118, respectively. Then, the output port P of the main CPU 112
The system reset instruction signal of H level is output from b1 to the one-shot pulse generation circuit 121 that constitutes the reset adjustment circuit 120, and the one-shot pulse generation circuit 12
A pulse signal of 1 to L level has a predetermined time (for example, 1 m
(during s) and output to the AND circuit 122. And AND
An L-level system reset signal is output from the circuit 122 to the main CPU 112, the main CPU 112 determines that the system reset signal has changed from the H level to the L level, and the main CPU 112 is system reset.

[Main Flow of Game] Next, the main flow of the game will be described with reference to FIGS. 9 to 12. Figure 9
FIG. 6 is an explanatory diagram of a jackpot lottery counter. Figure 10
It is a flow chart which shows a flow of the first sort starting mouth processing which main CPU112 performs. FIG. 11 shows the main CPU
It is a flow chart which shows the flow of special design control which 112 performs. FIG. 12 is a flowchart showing the flow of the RAM clearing process executed by the main CPU 112.
In the following description, it is assumed that the symbol display device 32a variably displays special symbols at three horizontal positions on the screen,
The symbols that are variably or fixedly displayed are, in order from the left, the left symbol, the middle symbol, and the right symbol. In addition, in this embodiment, the time from the timing when the game ball passes through the first type starting opening 27 to the timing when it is detected by the first type starting opening switch 27a is 0.1 s.

(Big hit lottery counter) The big hit lottery counter Ct1 shown in FIG. 7 is a counter for determining whether or not it is a big hit, and a plurality of numerical values, "0" to "299" in this embodiment. Count 300 numbers. In addition, the big hit lottery counter Ct1 has a predetermined period from the initial value for starting counting, in this embodiment, 2
+1 is added in the cycle of ms, and 0 is cleared when the addition result exceeds the acquisition range. The initial value is updated by +1 every 2 ms. Also, in this embodiment, 300
Among the numerical values of, in the normal probability, “7” is set as the big hit value in the big hit value table (the table in which the big hit value is set), and in the high probability (probability variation), a plurality of numbers (for example, , "7", "67", "117", "1"
77 "," 217 "and" 247 "in total) are set in the jackpot value table as jackpot values. Here, the probability change means that the probability of a big hit has changed to a high probability game state.

(First-Type Start Port Processing) When the first-type start port switch 27a (FIG. 4) is turned on, the main CPU 112 is activated.
Determines that the first type starting port switch 27a is turned on by detecting the voltage change of the input port connected to the first type starting port switch 27a (step (hereinafter abbreviated as S) in FIG. 8). 10: Yes), it is determined whether the special symbol starting memory number U1 is less than "4" (S1)
2). Here, when it is determined that it is less than “4” (S12:
Yes), "1" is added to the special symbol starting memory number U1 (S14), one count value counted by the jackpot lottery counter Ct1 is acquired (S16), and the acquired count value is temporarily stored in the RAM 116. Store (S1
8). In addition, the above-described first-type starting opening process is performed by the ROM 114.
It is executed by the computer program recorded in.

(Special symbol control) The main CPU 112,
Whether or not the control command for controlling the symbol control device 32 is output to the symbol control device 32, that is, whether or not the special symbol is changing (S20 of FIG. 9), it is determined that it is not changing. Then (S20: No), it is determined whether or not the special symbol starting memory number U1 is "1" or more (S2).
2). Here, if the main CPU 112 determines that the special symbol starting memory number U1 is “1” or more (S22: Ye
s), "1" is subtracted from the special symbol starting memory number U1 (S
24), RA in S18 of the above-mentioned first type starting opening processing
The count value temporarily stored in M116 is read (S2
6). Subsequently, the main CPU 112 determines whether or not the probability variation flag indicating that the gaming state is probability variation is set (probability variation flag = 1 or 0) (S28).
Here, when the main CPU 112 determines that the probability variation flag is set (S28: Yes), it refers to the jackpot value table at the time of high probability (step S30), and S2.
Whether or not it is a big hit is determined based on whether or not the same big hit value as the count value read in 6 is set (S3).
4). For example, the count value read in S26 is "6.
If it is "7", it is determined as a big hit (S34: Ye.
s). Further, when the probability variation flag is not set (S28: No), the jackpot value table at the time of normal probability is referred to (S32), and whether or not the same jackpot value as the count value read in S26 is set. Based on this, it is determined whether or not it is a big hit (S34). For example, when the count value read in S26 is "7", it is determined to be a big hit (S34: Yes).

Subsequently, when the main CPU 112 determines that it is a big hit (S34: Yes), it sets a big hit flag indicating that a big hit has occurred (S36), and refers to the big hit symbol table for determining the big hit symbol, and hits the big hit. The symbol is determined (S38), and it is determined whether or not the selected big hit symbol is a probability variation symbol (S40). Here, the probability variation symbol means a specific symbol (for example, an odd number of jackpot symbols) among the jackpot symbols, and if the probability variation symbol is a jackpot, the game after the game of the jackpot is over,
Change suddenly. Here, if it is a probability variation pattern (S4
0: Yes), and the probability variation flag is set (S42). Further, when the main CPU 112 is not a big hit, that is, when it is determined that there is a loss (S34: No), the lost symbol that determines the lost symbol is referred to, and the lost symbol that is fixedly displayed as the left symbol, the middle symbol, and the right symbol, respectively. It is determined (S44). The jackpot symbol table is configured by associating a plurality of random numbers (for example, 0 to 9) with a plurality of special symbols (for example, 000 to 999),
The special symbol associated with the random number randomly selected by the main CPU 112 is determined as the jackpot symbol. Also,
The lost symbol table has a plurality of random numbers (for example, 0 to 0).
9) and a plurality of special symbols (for example, 0 to 9) are associated with each other, and the special symbol associated with the random number randomly selected by the main CPU 112 is determined as the lost symbol. If the determined lost design is the same as the jackpot design, the lost design is determined again.

Subsequently, the main CPU 112 determines the variation pattern of the special symbol by referring to the variation pattern table which determines the variation pattern of the special symbol (S46). The variation pattern includes a variation time of the special symbol, a type of reach when the reach is performed, a normal stop pattern when the reach is not performed, and the like. Then, the main CPU 112
The variation start command indicating the variation pattern determined in 46, the big hit symbol determined in S38 or the lost symbol determined in S44 is transmitted to the symbol control device 32 (S48). Then, the main CPU 112 proceeds to S46.
The measurement of the variation time of the special symbol indicated by the variation pattern determined in (S50) is started. Further, the main CPU 112 transmits the variation pattern designation command to the symbol control device 32, and at the same time, transmits the variation pattern designation command to the voice control device 79 and the lamp control device 300 (FIG. 4). As a result, the voice control device 79 outputs the sound effect in the pattern corresponding to the received fluctuation pattern designation command, and the lamp control device 300 lights various LEDs in the pattern corresponding to the received fluctuation pattern designation command. Let And the main CPU 112
When it is determined that the time when the measurement is started is up in S50 (S52: Yes), an all symbol stop command for instructing the stop of all symbols is transmitted to the symbol control device 32 (S5
4) The measurement time is reset (S56). Thereby, the symbol display device 32a confirms and displays the big hit symbol or the lost symbol. Further, the voice control device 79 stops the output of the sound effect, and the lamp control device 300 stops the lighting of the LED. The special symbol control is in the ROM 11
It is executed according to the computer program recorded in 4.

(RAM clear processing) Main CPU 112
Performs a security check to check whether or not the computer program recorded in the ROM 114 has an abnormality (S60 in FIG. 12), and initializes the work area of the RAM 116 (S62). Then the main CPU 112
Determines whether or not the RAM clear execution flag indicating that the RAM clear processing has been decided to be executed is set (S64), and if not set (S64).
64: No), and it is determined whether or not the RAM clear switch 10 (FIGS. 4, 6, and 7) has been pressed and turned on (S66). If it is determined that it is turned on here (S6
6: Yes), the RAM clear execution flag is set (S
68) and outputs a system reset instruction signal to the reset adjustment circuit 120 (S70). As a result, the system reset signal is output from the reset adjustment circuit 120 to the main CPU 112, so that the main CPU 112 enters the system reset state, that is, the hot reset state, and executes the security check process (S60).
The work area of the RAM 116 is initialized (S62). That is, the main CPU 112 uses the RAM clear switch 10
If it is determined that the RAM clear switch 10 is turned on, the RAM clear process is not immediately executed, the system is reset, and the security check process and the work area initialization process are executed. Therefore, at least the security check is performed after the RAM clear switch 10 is turned on. The execution of the RAM clearing process can be delayed by the time required to execute the process and the work area initialization process. In this embodiment,
Since the time required to execute the security check process is about 439 ms = about 0.4 s, at least about 0.4 s after the RAM clear switch 10 is turned on.
During the above period, the RAM clear process is not executed.

Then, the main CPU 112 determines that the RAM clear execution flag is set (S64: Y).
es), a message display command for instructing the display of the message M1 shown in FIG. 3 is transmitted to the symbol control device 32 (S74). As a result, the symbol display device 32a displays a message M1 having the content "RAM clear switch has been operated. RAM clear processing will be performed" on the screen as shown in FIG. Then main CPU 11
2 executes the RAM clearing process (S76). That is, the backup data stored in the RAM 116 is erased, and the value when the jackpot lottery counter Ct1 starts counting is returned to the initial value “0”. In S76, the RAM clear command is transmitted from the main CPU 112 to the sub CPU 212 of the payout control board 200, and the sub CPU 212 receives the command and then RA
The stored contents of M216 are deleted. Then main CPU1
12 clears the RAM clear execution flag (S78),
In S74, a message erase command for instructing to erase the message M1 displayed on the symbol display 32a is transmitted to the symbol controller 32 (S80). This allows
The symbol display 32a deletes the message M1 displayed in S74. And the main CPU 112
The control of the game is started (S82), such as detection of winning, lottery of big hit or loss, update of initial value of big hit lottery counter Ct1 and the like.

After that, the main CPU 112 continues to monitor whether or not the RAM clear switch 10 is turned on, and if the illegal action using the hanging board, the transmitter, etc.
Main CPU when AM clear switch 10 is turned on
When the same signal as the RAM clear signal transmitted to 112 is transmitted to the main CPU 112 (S66: Ye
s), S68 to S62 are executed, and the execution timing of the RAM clear processing is delayed. In addition, the main CPU 112
If the RAM clear switch 10 is not turned on (S66: No), whether the check data stored in the RAM 116 is correct data, for example, A5
It is determined whether or not it is A5H (S72). A5 here
If it is A5H (S72: Yes), control of the game is started (S82), and if it is not A5A5H (S7).
2: No), it is determined that abnormal data is stored in the RAM 116, and RAM clear processing is executed (S7).
6).

As described above, the initial value of the jackpot lottery counter Ct1 is not reset to "0" at the timing when the instruction to clear the RAM is issued due to an illegal act, but
When the RAM clear switch 10 is turned on, the hot reset state is set, and after the RAM clear switch 10 is turned on, at least about 0.4 seconds or more has elapsed, the RAM clear processing is executed. Therefore, the game ball is the first type starting opening 27.
Alternatively, if a RAM clear instruction is issued at the same time when the player wins the ordinary electric accessory 47 with both wings open, the RAM clear process is executed after a lapse of about 0.4 seconds or more. On the other hand, since the time from the timing at which the game ball passes through the first type starting opening 27 to the timing detected by the first type starting opening switch 27a is 0.1 s, RAM
0.3 s (=
0.4s-0.1s) or more before, the main CPU 112
Has obtained one jackpot lottery counter Ct1 and has completed the lottery. That is, when the game ball passes through the first-class starting opening 27, the RAM clear instruction is given, and the initial value of the jackpot lottery counter Ct1 is reset to "0", thereby passing through the first-class starting opening 27. The timing at which the game ball is detected by the first type starting opening switch 27a (the timing at which the main CPU 112 acquires the count value of the jackpot lottery counter Ct1) and the jackpot lottery counter C
It is not possible to match the count value of t1 with the timing of counting the big hit value “7”. The above R
The AM clearing process is executed according to the computer program recorded in the ROM 114.

[Effects of First Embodiment] (1) As described above, the pachinko machine 1 according to the first embodiment described above.
By using, instead of returning the initial value of the jackpot lottery counter Ct1 to "0" immediately after the RAM clear switch 10 is turned on, at least 0.4 seconds or more has elapsed after the RAM clear switch 10 was turned on. The initial value of the jackpot lottery counter Ct1 can be returned to "0". In other words, the time required for the main CPU 112 to execute the security check process is the first type starting opening switch 27a after the game ball passes through the first type starting opening 27.
Since it is longer than the time required to be detected by the game ball, the game ball is detected by the first-type starting opening switch 27a before the RAM clear processing is performed, and the main CP
U112 is a jackpot lottery counter C at the time of its detection.
This means that the count value of t1 is acquired and the lottery is completed. Therefore, the jackpot lottery counter Ct1 is counted from "0" by instructing the RAM clear by an illegal means aiming at the timing 0.086s after the game ball passes through the first type starting opening 27. And the timing to count the jackpot count value and the main C
Since the timing at which the PU 112 acquires the count value of the jackpot lottery counter Ct1 cannot be matched, there is no possibility that the jackpot will be illegally generated. In addition, if a pachinko hall player turns on the power while pressing the RAM clear switch 10 when the pachinko hall is opened, the RAM clear process is performed, and the data backed up in the RAM and generated during the trial shooting can be erased.

(2) Further, since the message M1 is displayed on the screen of the symbol display 32a on which the result of lottery, which is the biggest concern of the player, whether it is a big hit or a loss, is displayed to the player. I can surely convey it. Therefore, the player who sees the message M1 knows that the RAM clear is executed after the timing of issuing the RAM clear instruction.
If the RAM clear instruction is issued at the same time as when 7 is passed, the initial value of the jackpot lottery counter Ct1 cannot be returned to "0", and it is understood that the jackpot cannot be generated.
