  On the production control board 90, a plurality of production effect LEDs 52 arranged on the front door 1b of the slot machine 1, speakers 53L and 53R, speakers 153L and 153R, production switches 54 used for production (see FIG. 1), reel LEDs 55, A liquid crystal display 51 provided in an effect unit 200, which will be described later, speaker LEDs 60L and 60R that illuminate sound transmitting portions 154L and 154R of the speakers 153L and 153R, speaker frame LEDs 61L and 61R, and a display LED 62a for displaying the display device 500, 62b, a panel LED 63 that illuminates the title sheet 590, and the like are connected, and these effect devices are driven based on control by a sub-control unit 91 (described later) mounted on the effect control board 90. .

  In this embodiment, the sub-control unit 91 mounted on the effect control board 90 causes the effect effect LED 52, the speakers 53L and 53R, the speakers 153L and 153R, the reel LED 55, the liquid crystal display 51, the speaker LEDs 60L and 60R, and the speaker frame. Although the output control of the rendering device such as the LEDs 61L and 61R, the display LEDs 62a and 62b, and the panel LED 63 is performed, the output control unit that directly controls the output of the rendering device is provided separately from the sub-control unit 91. Mounted on the control board 90 or another board, the sub control unit 91 determines the output pattern of the rendering device based on the command from the main control unit 41, and the output control unit based on the output pattern determined by the sub control unit 91 May be configured to perform output control of the rendering device. So that the output control of the effect device by both parts is carried out.

  Similar to the main control unit 41, the effect control board 90 includes a sub CPU 91a, ROM 91b, RAM 91c, and a microcomputer provided with an I / O port 91d. The sub control unit 91 controls the effect, and the effect control board 90. Drive control of the display control circuit 92 that performs display control of the liquid crystal display 51 connected to the display, the effect LED 52, the reel LED 55, the speaker LEDs 60L and 60R, the speaker frame LEDs 61L and 61R, the display LEDs 62a and 62b, and the panel LED 63. LED drive circuit 93, speakers 53L and 53R, audio output circuit 94 for controlling audio output from speakers 153L and 153R, a reset signal to sub CPU 91a when power is turned on or when an initialization command from sub CPU 91a is not input for a certain period of time Reset circuit 95, A switch detection circuit 96 that detects a detection signal input from switches such as the effect switch 54 connected directly to the output control board 90 or via a relay board, and a clock device that outputs time information including date information and time information 97. The power supply voltage supplied to the slot machine 1 is monitored, and when a voltage drop is detected, a power drop detection circuit 98 that outputs a voltage drop signal to that effect to the sub CPU 91a, an unillustrated accessory, etc. A motor drive circuit 99 that performs driving, other circuits, and the like are mounted, and the sub CPU 91a receives various commands for performing effects in response to commands transmitted from the game control board 40, and effects control. Each part of the control circuit mounted on the substrate 90 is controlled directly or indirectly.

  Similar to the main CPU 41a, the sub CPU 91a has an interrupt function (including an interrupt prohibition function). One of the interrupt terminals of the sub control unit 91 is connected to a strobe (INT) signal line that is output when the main control unit 41 transmits a command, among the command transmission lines, and the sub CPU 91a receives the strobe signal. An interrupt is generated based on the input to acquire a command from the main control unit 41 and execute a command reception interrupt process to be stored in the buffer. Further, the sub CPU 91a executes an interrupt process (sub) to be described later by generating an interrupt every time the number of clock inputs reaches a certain number, that is, every certain interval. One of the interrupt terminals of the sub-control unit 91 is connected to the power interruption detection circuit 98, and the sub CPU 91a responds to the input of the voltage drop signal output from the power interruption detection circuit 98. Execute processing (sub). Further, when an unused interrupt occurs in the sub CPU 91a, an unused interrupt process for immediately returning to the original process is executed.

  The sub-control unit 91 is also supplied with backup power at the time of a power failure, and the data stored in the RAM 91c is held while the backup power is supplied.

  In the present embodiment, although not shown in detail, a game relay board that relays between the game control board 40 and various game electronic components (for example, reel motors 32L, 32C, and 32R), an effect control board 90, and the like. An effect relay board for relaying various effect electronic components (for example, panel LEDs 63) is provided separately. For example, both the game relay board and the effect relay board are formed by one relay board. You may make it share, and by doing in this way, wiring etc. can be collectively wired now to a predetermined location.

  In the slot machine 1 of the present embodiment, the medal payout rate changes according to the set value. Specifically, the medal payout rate is changed by using a winning probability corresponding to a set value in an internal lottery described later. The set value is composed of 6 levels of 1 to 6, with 6 being the highest payout rate and the payout rate being lower as the value is decreased in the order of 5, 4, 3, 2, 1. That is, when 6 is set as the set value, the advantage is highest for the player, and as the value decreases in order of 5, 4, 3, 2, 1, the advantage decreases stepwise.

  In order to change the setting value, it is necessary to turn on the power of the slot machine 1 after the setting key switch 37 is turned on. When the setting key switch 37 is turned on and the power is turned on, the setting value read from the RAM 41c is displayed on the setting value display 24 as a display value, and the setting value can be changed by operating the reset / setting switch 38. Transition to the setting change state. When the reset / setting switch 38 is operated in the setting change state, the display value displayed on the setting value display 24 is updated one by one (when further operation is performed from the setting 6, the display returns to the setting 1). . When the start switch 7 is operated, the display value is determined as the set value. Then, when the setting key switch 37 is turned OFF, the determined display value (setting value) is stored in the RAM 41c of the main control unit 41, and the state shifts to a state in which the game can proceed.

  In order to confirm the set value, after the game is over, the setting key switch 37 may be turned on with no bet amount set. When the setting key switch 37 is turned on in such a situation, the setting value read out from the RAM 41c is displayed on the setting value display 24, thereby shifting to a setting confirmation state in which the setting value can be confirmed. In the setting confirmation state, the game cannot be progressed, and by turning the setting key switch 37 to the OFF state, the setting confirmation state is ended and the state in which the game can proceed is returned.

  In the slot machine 1 of the present embodiment, when the main CPU 41a detects a voltage drop signal from the power interruption detection circuit 48, a power interruption interrupt process (main) is executed. In the power interruption interrupt processing (main), the register is saved in a stack of a RAM 41c, which will be described later, and data for destructive diagnosis (in this embodiment, 5AH) in which any bit is 1 in the RAM 41c, that is, a specific value other than 0 In addition to storing data, the RAM parity adjustment data is calculated so that the RAM parity based on the data stored in all areas of the RAM 41c is 0, and the RAM 41c is stored. The RAM parity is a value calculated as an exclusive OR of values stored in each bit of the corresponding area (all areas in this embodiment) of the RAM 41c. Therefore, if the RAM parity based on the data stored in all areas of the RAM 41c is 0, the RAM parity adjustment data is 0, and the RAM parity based on the data stored in all areas of the RAM 41c is 1. In this case, the RAM parity adjustment data is 1.

  The main CPU 41a calculates the RAM parity based on the data stored in all areas of the RAM 41c at the time of activation, confirms the value of the destructive diagnosis data, the RAM parity is 0, and the destructive diagnosis The processing state of the main CPU 41a is restored to the state before the power interruption based on the data stored in the RAM 41c on the condition that the value of the data for use is correct, but the RAM parity is not 0 (in the case of 1) or is destroyed. If the value of the diagnostic data is not correct, it is determined that the RAM is abnormal, and the RAM abnormal error code is set in the register to control the RAM abnormal error state so that the progress of the game is disabled. Unlike the other error states, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and a new set value is set in the setting change state described above. It will not be released until

  In this embodiment, all the data stored in the RAM 41c is held by the backup power source even in the event of a power failure, and when the main CPU 41a determines that the data in the RAM 41c is normal when the power is turned on. Although the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 41c, only the data necessary for the restoration of the control state in the event of a power failure is backed up among the data stored in the RAM 41c. It may be configured to return to the control state before power interruption based on the backed up data.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player For example, it is not necessary to restore the state of all input ports to the state before power interruption.

  In addition, when the sub CPU 91a detects the voltage drop signal from the power interruption detection circuit 98, the sub CPU 91a also executes a power interruption interrupt process (sub). In the power interruption interrupt processing (sub), the register is saved in a stack of a RAM 91c described later, and destructive diagnosis data in which any bit is 1 is stored in the RAM 91c, and data stored in all areas of the RAM 91c. The RAM parity adjustment data is calculated so that the RAM parity based on 0 becomes 0 and stored in the RAM 91c.

Then, the sub CPU 91a calculates the RAM parity based on the data stored in all areas of the RAM 91c at the time of activation, and based on the data stored in the RAM 91c on the condition that the RAM parity is 0. The processing state of the sub CPU 91a is restored to the state before the power interruption. If the RAM parity is not 0 (1), it is determined that the RAM is abnormal and the RAM 91c is initialized. In this case, unlike the main C PU 4 1a, RAM 91c will not be only disabled execution of the effect in the initialization.

  In this embodiment, all data stored in the RAM 91c is held by the backup power source even during a power failure, and the sub CPU 91a determines that the data in the RAM 91c is normal when the power is turned on. Although the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 91c, only the data necessary for restoration of the control state is backed up in the event of a power failure out of the data stored in the RAM 91c. It may be configured to return to the control state before power interruption based on the backed up data.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player It is not necessary to restore the state of the input port or the progress in the middle of the production when it is interrupted. For example, while backing up only data indicating the gaming state such as whether it is in the BB or the normal gaming state, other than the effect corresponding to the gaming state (the effect during the BB during the BB, the normal effect when in the normal gaming state) If a power outage occurs during the execution of a specific production (such as a small role announcement), it will be backed up when the power is turned on instead of resuming the specific production that was being performed at the next power-on. An effect corresponding to the gaming state being played may be executed from the beginning.

  Next, initialization of the RAM 41c of the main control unit 41 will be described. The storage area of the RAM 41c of the main control unit 41 is divided into an important work, a general work, a special work, a set value work, an RT work, a stop phase work, a non-saved work, an unused area, and a stack area.

  The important work is a work in which data that is inconvenient to be initialized at the end of the BB, such as various display devices and LED display data, input / output data of the I / O port 41d, and a game time clock counter, is stored. The general work is a work that stores data that can be initialized at the end of the BB, such as an internal winning flag, a stop control table, a stop symbol, the number of medals paid out, and the total number of medals paid out in the BB. The special work is a work that stores data to be initialized only before the start of setting, such as data for transmitting a command to the effect control board 90 and various software random numbers. The set value work is a work in which a set value used when performing a lottery in the internal lottery process is stored. After initializing 0 before setting is started (before shifting to the setting change mode), 1 is stored. The set value that is corrected and newly set at the end of the setting (when the setting change mode is ended) is stored. The RT work is a work in which an RT flag indicating that the current game state is one of the replay times (hereinafter abbreviated as RT) (0) to (4) and the number of remaining RT games are stored. is there. The stop phase workpiece is a workpiece in which data indicating the stop phase of the reel motors 32L, 32C, 32R is stored, and data indicating the stop phase is stored when the reel motors 32L, 32C, 32R are stopped. The Rukoto. The unsaved work is a work that holds the state of various switches, and a value is always set regardless of whether or not the data in the RAM 41c is destroyed at the time of activation. The unused area is an unused area in the storage area of the RAM 41c, and is initialized if any one of a plurality of initialization conditions described later is satisfied. The stack area is an area in which data saved from the register of the main CPU 41a is stored, and the unused stack area is established by any one of a plurality of initialization conditions to be described later, like the unused area. In this case, the used stack area is not initialized because the program continues.

  In this embodiment, the main CPU 41a operates when the RAM abnormal error occurs, when the setting key switch 37 and the reset / setting switch 38 are both ON, and when only the setting key switch 37 is ON. At the end, when the setting key switch 37 and the reset / setting switch 38 are both OFF, when the data in the RAM 41c is not destroyed, the six initialization conditions at the end of one game are satisfied In addition, six types of initialization are performed in different regions to be initialized according to each initialization condition.

  Initialization 0 is initialization that is performed when a RAM abnormality error occurs. In initialization 0, all the areas (including the unused area and the unused stack area) of the storage area of the RAM 41c except the used stack area are stored. It is initialized. Initialization 1 is an initialization performed before both the setting key switch 37 and the reset / setting switch 38 are turned on at the time of start-up, and when shifting to the setting change mode. Of the storage area of the RAM 41c, all areas (including the unused area and the unused stack area) other than the used stack area and the RT work are initialized. Initialization 2 is an initialization performed only when the setting key switch 37 is in an ON state at the time of startup and shifts to the setting change mode. In the initialization 2, in the storage area of the RAM 41c, All the areas (including the unused area and the unused stack area) except the in-use stack area, the RT work, and the stop phase work are initialized. Initialization 3 is initialization performed at the end of the BB. In initialization 3, a general work, an unused area, and an unused stack area are initialized in the storage area of the RAM 41c. The initialization 4 is an initialization performed when both the setting key switch 37 and the reset / setting switch 38 are in an OFF state at the time of startup and the data in the RAM 41c is not destroyed. The stored work, unused area, and unused stack area are initialized. Initialization 5 is initialization performed at the end of one game. In initialization 5, an unused area and an unused stack area are initialized in the storage area of the RAM 41c.

  In this embodiment, initialization 1 and initialization 2 are performed before transition to the setting change mode. However, they may be performed at the end of the setting change mode, that is, after the setting is confirmed. In this case, if the set value work is initialized, the determined set value is lost. Therefore, the set value work is not initialized.

  As described above, in order to start the reel smoothly, it is necessary to specify the exact stop position of the rotor when the reel motor starts rotating. If the data of the RAM 41c including the data indicating the phase is initialized, it is impossible to specify the exact stop position of the rotor after the setting is changed. When the reel motor is first rotated, the rotor is suddenly changed. Because the permanent magnet is attracted to the excitation phase and the reel vibrates at the start of rotation, the reel rotation mode becomes unclear and the player has forgotten that the setting has been changed. There is.

  In contrast, in this embodiment, the data indicating the stop phase when the reel motors 32L, 32C, 32R are stopped is set in the stop phase work assigned to the RAM 41c, so that the exact stop position of the rotor can be specified. And When only the setting key switch 37 is in an ON state at the time of start-up, and when shifting to the setting change mode, the RAM 41c is initialized, but the stop phase work is not initialized. Even in this gaming state, data indicating the stop phase of the reel motors 32L, 32C, 32R stored in the stop phase work is maintained. For this reason, even when the reel motors 32L, 32C, and 32R are first rotated after the setting is changed, it is possible to specify the exact stop positions of these rotors, and even in such a situation, the reels can be smoothed. It is possible to start rotation. As a result, the reel does not vibrate when the reel is first rotated after the setting is changed, and it is possible to prevent the player from seeing that the setting has been changed.

  In addition, both the setting key switch 37 and the reset / setting switch 38 are in an ON state at the time of starting, and the RAM 41c including the stop phase work can be initialized when shifting to the setting change mode. Therefore, it is possible to select whether or not to initialize the stationary phase work according to the operation method when shifting to the setting change mode at the time of activation. As a result, it is possible to initialize the RAM 41c including the stop phase work, so that an illegal program or the like becomes resident by using the stop phase work assigned to store the excitation phase of the stepping motor. Can be prevented.

  In this embodiment, the RAM 41c is initialized when only the setting key switch 37 is activated and shifted to the setting change mode. At this time, by not initializing the stop phase work, Even in the gaming state after the setting change, the reel motors 32L, 32C, and 32R are first rotated after the setting change by maintaining the data indicating the stop phase of the reel motors 32L, 32C, and 32R stored in the stop phase work. Even in this case, these stop phases can be specified, but even when the data in the RAM 41c is cleared as the set value is changed, a specific initial excitation phase is set as the stop phase work. The excitation phase indicated by the data set for the stop phase work is excited before the game can be started after the setting is changed. 32L, 32C, when rotating the 32R, may be able to identify these stop phases.

  In the slot machine 1 according to the present embodiment, the prescribed number of bets that can be set according to the gaming state is determined as described above, and the prescribed number of bets that are determined according to the gaming state is set. It becomes possible to start the game on the condition. In the present embodiment, there are RB and RT (0) to (4) as gaming states, and in RB, a prescribed number of bets is set to 2, and in gaming states other than RB, a prescribed number of bets is set to 3. In RT, when 3 is set as the bet number, the game can be started. In gaming states other than RB, the game can be started when 3 is set as the bet number. In the present embodiment, all of the pay lines L1 to L5 are activated when a specified number of bets corresponding to the gaming state are set.

  In the slot machine 1 of this embodiment, when all of the reels 2L, 2C, 2R are stopped, a winning combination is obtained when a combination of symbols called “comb” is arranged on the activated winning line (hereinafter simply referred to as a winning line). It becomes. The combination may be a combination of the same symbols or a combination including different symbols. The type of winning combination is determined according to the game state, but it can be roughly divided into a small role with payout of medals and a replay that can start the next game without the need to set the number of bets. There are a game combination and a special combination with a transition of the game state. Below, a small role and a re-playing role are collectively called a general role. In order for winning of each combination determined according to the gaming state to occur, it is necessary to win an internal lottery to be described later and set a winning flag of the combination in the RAM 41c.

  Of the winning flags for each of these combinations, the winning flag for the small role and the re-playing role is valid only in the game in which the flag is set, and is invalid in the next game. It is valid until a combination of combinations permitted by the flag is completed, and is invalid in a game having a combination of combinations permitted. In other words, once the special combination winning flag is won, even if the combination of the combinations permitted by the flag cannot be made, the winning flag is not invalidated and is carried over to the next game. It becomes.

  In the slot machine 1, as a special role, a big bonus (1) (2) is used as a special game, a replay (1) and a replay (2) are used, and a small role is grape, watermelon, cherry, and 10 ( 1) to (3), two-sheet combination (1) to (4), and one-sheet combination (1) to (4) are defined.

  Grapes are awarded when a combination of “grape-grape-grape” is aligned on any of the winning lines in any gaming state, and 10 medals are paid out regardless of the gaming state.

  A watermelon is awarded when a combination of “watermelon-watermelon-watermelon” is aligned on any of the winning lines in any gaming state, and 10 medals are paid out in RB, and 5 in gaming states other than RB. A medal is paid out.

  Cherry is awarded when the symbol “Cherry” is derived on any of the winning lines for the left reel in any gaming state, 5 medals are paid out in RB, and 4 in gaming states other than RB. A medal is paid out. The “cherry” symbol is controlled so that it always stops at either the upper or lower level of the left reel, and the winning line of the winning lines L1 and L3 or the winning line of the winning lines L2 and L4 is controlled. Since the combination of cherries is aligned and the cherries are won on the two winning lines, 10 medals are paid out in the RB, and 8 medals are paid out in the gaming state other than the RB. .

  The 10 winning combination (1) wins when a combination of “white 7-black 7-plum” is aligned on any of the winning lines in any gaming state, and 10 medals are paid out regardless of the gaming state. It is. The 10 winning combination (2) wins when the combination of “White 7-White 7-Plum” is aligned on any of the winning lines in any gaming state, and 10 medals are paid out regardless of the gaming state. It is. The 10 winning combination (3) wins when the combination of “white 7-orange-plum” is arranged on any of the winning lines in any gaming state, and 10 medals are paid out regardless of the gaming state. .

  The two-player combination (1) wins when the combination of “Replay-Plum-Replay” is aligned on any of the winning lines in any game state, and 4 medals are paid out in the RB. In the gaming state, two medals are paid out. Two-player combination (2) wins when the combination of “Replay-Watermelon-Replay” is aligned on any of the winning lines in any gaming state, and 4 medals are paid out in RB, except for RB In the gaming state, two medals are paid out. Two-player combination (3) wins when the combination of “Replay-Cherry-Replay” is aligned on any of the winning lines in any game state, and 4 medals are paid out in RB, except for RB In the gaming state, two medals are paid out. Two-player combination (4) wins when the combination of “Replay-Bell-Replay” is aligned on any of the winning lines in any gaming state, and in RB, four medals are paid out, except for RB In the gaming state, two medals are paid out.

  A single player (1) wins when the combination of “Grape-Plum-Grape” is placed on any of the winning lines in any game state, and 4 medals are paid out in the RB. In the game state, one medal is paid out. A single player (2) wins when the combination of “Grape-Watermelon-Grape” is placed on any of the winning lines in any game state, and 4 medals are paid out in RB. In the game state, one medal is paid out. The single player (3) wins when a combination of “Grape-Cherry-Grape” is placed on any of the winning lines in any game state, and 4 medals are paid out in RB, except for RB In the game state, one medal is paid out. A single player (4) wins when the combination of “Grape-Bell-Grape” is aligned on any of the winning lines in any game state, and 4 medals are paid out in RB, except for RB In the game state, one medal is paid out.

  Replay (1) is won when a combination of “Replay-Replay-Replay” is aligned on any of the winning lines in RT (0) to (4), and Replay (2) is received from RT (0) to ( In 4), when a combination of “Replay-Replay-Grape” is arranged on any of the winning lines, a winning is awarded. When either one of the replays (1) or (2) wins, no medals will be paid out, but the next game can be started without setting the number of bets again. This is substantially the same as paying out the three medals.

  In this embodiment, since the replay (2) is always won with either BB (1) or (2) in RT (2) (3), the game ends when BB (1) (2) is won. When the configuration for shifting to RT (4) without adopting the wait is adopted, the combination of replay (2) is not aligned on the winning line in RT (2) (3).

  BB (1) is awarded when a combination of “Black 7-Black 7-Black 7” is aligned on any of the winning lines in RT (0) to (4), and BB (2) becomes RT (0 ) To (4), when a combination of “white 7-white 7-white 7” is aligned on any of the winning lines, a winning is achieved. In addition, when adopting a configuration that shifts to RT (4) without waiting for the end of the game at the time of winning BB (1) (2), BB (1) (2) is only in RT (4) Winning is possible.

  When either BB (1) or (2) wins, the gaming state shifts to BB and simultaneously shifts to RB. RB is a gaming state that is advantageous to the player over other gaming states by increasing the winning probability of small roles, especially grapes. When RB starts, when 12 games are digested, or 8 games win ( When the type of a combination is allowed), it ends either whichever comes first. When the RB is finished, if the BB is not finished, the process proceeds to the RB again, and the RB is repeatedly controlled until the BB is finished. That is, during BB, it is always controlled to RB. Then, the process ends when the total number of medals paid out to the player in the BB exceeds 348. At the end of the BB, the RB is also ended regardless of whether or not the RB end condition is satisfied.

In addition, the light guide plate 505 can be inserted into the insertion grooves 508a and 508b from above and removed upward by removing the upper frame 504d as shown in FIG.

  Since the light guide plate 505 is detachably provided from the left frame 504a, the right frame 504b, and the lower frame 504c as described above, the light guide plate 505 can be easily replaced. When exchanging to another light guide plate 505 having different information, only the light guide plate 505 can be easily replaced.

  As shown in FIG. 8, the front light guide plate 505a and the rear light guide plate 505b have a horizontally long rectangular shape when viewed from the front by a transparent synthetic resin plate such as acrylic or polycarbonate having a predetermined front-rear width dimension L3 {plate thickness (for example, 5 mm)}. Is formed. The light guide plate 505 is not necessarily transparent as long as it has translucency. For example, the light guide plate 505 may be colored or translucent.

  On the back surface 505B of the front light guide plate 505a, reflection portions 510a to 510c for reflecting the light from the display LED 62a and emitting it from the front surface 505F are formed (see FIG. 8A). The reflective portion 510a is formed to represent the characters “Large”, the reflective portion 510b is represented as “Hi”, and the reflective portion 510c is represented as “Li”. The left region, the middle region, and the right region obtained by dividing the front surface 505F into three equal parts in the horizontal direction. It is arranged to fit in each.

  Reflecting portions 511a to 511c are formed on the rear surface 505B of the rear light guide plate 505b to reflect the light from the display LED 62b and emit the light from the front surface 505F (see FIG. 8B). The reflector 511a is a character having a drum, the reflector 511b is a character “CHANCE!”, The reflector 511c is formed to represent a girl character, and a left region, a middle region, and a front surface 505F divided into three equal parts. It is arranged to fit in each right area.

  Therefore, these reflection portions 510a and 511a, 510b and 511b, 510c and 511c are arranged at positions where the front light guide plate 505a and the rear light guide plate 505b are overlapped in the front-rear direction with the frame frame body 504 inserted.

  As shown in FIGS. 8C and 8D, these reflecting portions 510a to 510c and 511a to 511c have a substantially triangular wave shape in which the sectional view in the traveling direction of the light guided through the light guide plate 505 has a constant pitch. It is formed in an uneven state (rough surface). Specifically, it is configured by a molding method in which an uneven portion is formed on the back surface 505B of the light guide plate 505 by a stamper or injection. For example, a silk printing method in which reflective dots are printed with white ink on an acrylic plate, an acrylic plate, You may comprise a reflection part by the sticking dot system which affixed the reflecting plate with the dot-shaped adhesive material, a groove processing system, etc.

  In this embodiment, the reflection portions 510a to 510c and 511a to 511c on the back surface 505B of the light guide plate 505 are uneven portions having a substantially triangular wave shape when viewed in the light traveling direction. However, the present invention is limited to this. The reflecting portions 510a to 510c and 511a to 511c can be variously modified as long as they form a reflecting surface capable of reflecting light toward the front surface 505F, such as a substantially semicircular shape. In FIGS. 8A and 8B, these reflecting portions 510a to 510c and 511a to 511c are represented as characters or designs surrounded by a frame line, but actually there is no frame line, and the dots A character and a picture are formed by the gathering.

  In this embodiment, characters and pictures are exemplified as display information that can be displayed by the light guide plate 505. In addition to these, other display information including decorations such as symbols, patterns, or patterns is also included. Display may be possible.

As shown in FIGS. 9 and 11, the upper frame 504 d, a pair of front and rear lens groove 512a that is penetrated vertically while being extended in the lateral direction, 512b are formed. The lens grooves 512a and 512b are arranged side by side across the central wall portion 513, and are formed in a tapered shape so that the front and rear width dimension gradually decreases from the upper side to the lower side. In addition, a pair of front and rear locking claws 517a and 517b facing the lens grooves 512a and 512b are provided on the left and right ends of the wall portion 513, and the condensing lens 507 fitted in the lens grooves 512a and 512b is provided. The upper end is locked to restrict upward movement.

On the upper surface opening of the upper frame 504 d, the display LED 62a, 62b are LED substrate 514 provided on the lower surface of the substrate placement part 515 of the fittable concave is formed. By disposing the LED substrate 514 on the substrate disposition portion 515, the display LEDs 62a and 62b are disposed opposite to the upper surface openings of the front and rear lens grooves 512a and 512b, and screws N2 attached to the left and right end portions thereof are screwed. The LED substrate 514 can be fixed by screwing into the holes 516a and 516b.

  As shown in FIGS. 9 and 10, the front lens 507 a and the rear lens 507 b are formed in a horizontally long plate shape with a light-transmitting synthetic resin material such as acrylic or polycarbonate, and extend along the upper end surface 505 </ b> H of the light guide plate 505. And disposed between the upper end surface 505H of the light guide plate 505 and the display LEDs 62a and 62b (see FIG. 14).

  Specifically, a plurality of substantially semicircular convex portions 518 bulging downward in front view are continuously arranged in parallel in the longitudinal direction on the lower sides of the front lens 507a and the rear lens 507b. Each convex portion 518 is formed corresponding to each of the display LEDs 62a and 62b, and the front surface of each convex portion 518, that is, the lower surface facing the upper end surface 505H of the light guide plate 505 in the front lens 507a and the rear lens 507b. The end surface 507L (outgoing surface) constitutes a plurality of curved surfaces (lens surfaces).

  The plurality of convex portions 518 are not limited to one-to-one correspondence with display LEDs, and for example, a plurality of convex portions 518 (lens surfaces) corresponding to two or more LEDs (light emitting bodies) may be provided. Further, although the front lens 507a and the rear lens 507b are formed of a single member integrally provided with a plurality of convex portions 518, a plurality of display LEDs 62a and 62b arranged in parallel along the upper end surface 505H. Correspondingly, a plurality of condensing lenses formed separately from each other may be provided.

  On the upper sides of the front lens 507a and the rear lens 507b, a plurality of curved bulges 519 that bulge slightly upward in a front view are continuously formed in the longitudinal direction. Each bulging portion 519 is formed corresponding to each of the display LEDs 62a and 62b, and the top surface of each bulging portion 519, that is, the front lens 507a and the rear lens 507b are opposed to the display LEDs 62a and 62b. The end surface 507H (incident surface) constitutes a plurality of curved surfaces (lens surfaces). Note that the curved upper end surface 507H has a smaller curvature than the curved lower end surface 507L, and is formed to a slight extent.

  The front-rear width dimension L1 (plate thickness) of the lowermost portion of the lower end surface 507L of the front lens 507a and the rear lens 507b is shorter than the front-rear width dimension L2 (plate thickness) of the uppermost portion of the upper end surface 507H. (L1 <L2). The front-rear width dimension L1 of the lower end surface 507L is substantially the same as the front-rear width dimension L3 of the light guide plate 505 (L1≈L3), and the front-rear width dimension L2 of the upper end surface 507H is the light emitting surface of the display LEDs 62a and 62b. The front-rear width dimension L4 of 62c (see FIG. 13) is substantially the same.

  The front surface 507F forms a flat inclined surface that gradually inclines toward the lower end surface 507L from the upper end surface 507H, and the rear surface 507B has a flat surface that inclines toward the lower front surface from the upper end surface 507H toward the lower end surface 507L. It constitutes a simple inclined surface. That is, since the front surface 507F and the back surface 507B form inclined surfaces that gradually incline toward each other from the upper end surface 507H toward the lower end surface 507L, the front lens 507a and the rear lens 507b are arranged from the upper end surface 507H to the lower end surface. It is formed in the shape of a substantially inverted letter C in the longitudinal section in which the plate thickness gradually decreases toward 507L.

  Therefore, the front-rear width dimension (plate thickness) of the lower end surface 507L of the front lens 507a and the rear lens 507b becomes shorter as it approaches the lowest part of each convex part 518, and the front-rear width dimension L1 becomes the smallest in the lowest part. . In this embodiment, short non-inclined surfaces 507Fa and 507Bb that are parallel to each other are provided between the upper end surface 507H and the inclined surface.

  Hook pieces 520a and 520b are formed on the left and right ends of the front lens 507a and the rear lens 507b, and are locked from above by ribs (not shown) provided in the upper frame 504d, and in the lens grooves 512a and 512b. Is supposed to be retained.

  As shown in FIG. 11, the front lens 507a and the rear lens 507b configured as described above are inserted into the front and rear lens grooves 512a and 512b from above through the upper surface opening of the upper frame 504d. Then, the upper end surface 507H is inserted until it is positioned at substantially the same height as the upper surface openings of the lens grooves 512a and 512b, and in the state where the hook pieces 520a and 520b are locked to the ribs (not shown), the lower end surface 507L is A concave groove part into which the light guide plate 505 is inserted is formed at a position slightly above the lower surface opening of the lens grooves 512a and 512b and in the lower part in the lens grooves 512a and 512b.

  Actually, when the upper frame 504d is connected between the upper ends of the left frame 504a and the right frame 504b, the front light guide plate 505a and the rear light guide plate 505b are inserted into the lower portions of the lens grooves 512a and 512b. As described above, the front light guide plate 505a and the rear light guide plate 505b are inserted into the lower portions of the lens grooves 512a and 512b, so that the upper end surfaces 505H of the front light guide plate 505a and the rear light guide plate 505b and the lower end surfaces of the front lens 507a and the rear lens 507b. 507L faces the lens grooves 512a and 512b with a predetermined gap therebetween. As described above, the front light guide plate 505a and the rear light guide plate 505b are fitted into the lower portions of the lens grooves 512a and 512b, thereby preventing the positional deviation in the front-rear direction between the upper end surface 505H and the lower end surface 507L.

  In particular, as shown in FIG. 11C, a space is formed between the lower end surface 507L and the upper end surface 505H because the lower end surface 507L is formed as a curved surface by the convex portion 518. The space is sealed by the non-transparent wall surface of the upper frame 504d constituting the lens grooves 512a and 512b, so that the light emitted from the lower end surface 507L is incident on the upper end surface 505H without leaking to the surroundings. The

As shown in FIG. 12, the display device 500 configured in this way is assembled on the front side of the liquid crystal display 51 (see FIG. 6). In the state assembled on the front side, the frame frame 504 surrounds the periphery of the display screen 51a, and the entire front and back light guide plates 505a and 505b cover the entire display screen 51a.

  The rear light guide plate 505b is disposed on the front side with a predetermined gap (for example, about 20 mm) from the display screen 51a, and the front light guide plate 505a has a predetermined gap (for example, the rear light guide plate 505b). About 15 mm) on the front side. The gap width can be changed variously. Alternatively, the front light guide plate 505a and the rear light guide plate 505b may be disposed in contact with each other.

  Further, the liquid crystal display 51 and the display device 500 are configured separately, and can be detachably assembled to each other so that the liquid crystal display 51 and the display device 500 are integrated. Since it can be attached to or removed from the effect unit 200, workability is improved, and a relative position between the liquid crystal display 51 and the display device 500 does not shift when attached to the effect unit 200.

Further, the replacement work of the liquid crystal display 51, the front and rear light guide plates 505a and 505b, and the display LEDs 62a and 62b can be performed separately in a state of being separated from each other. Further, the display device 500 includes a light guide plate 505, an LED substrate 514, a condenser lens 507, and the like integrated with each other via a frame frame body 504. Therefore, the workability is improved, and the relative positional relationship of each member is changed by the removal by replacement so that the light emission display is not adversely affected.

  Next, as shown in FIGS. 13 and 14, the display device 500 is arranged on the upper side of the front light guide plate 505 a in a state where the condenser lens 507, the LED substrate 514, and the light guide plate 505 are integrally assembled to the frame frame 504. A front lens 507a is disposed along the front lens 507a. A plurality of display LEDs 62a are arranged in the longitudinal direction above the front lens 507a, and a rear lens 507b is disposed along the upper side of the rear light guide plate 505b. A plurality of display LEDs 62b are juxtaposed in the longitudinal direction above the lens 507b. That is, the condensing lens 507 is disposed between the light guide plate 505 and the display LEDs 62a and 62b.

  Specifically, in the condenser lens 507, the lower end surface 507L faces the upper end surface 505H of the light guide plate 505, and the upper end surface 507H faces the light emitting surface 62c of each of the display LEDs 62a and 62b. In addition, each of the display LEDs 62a and 62b is disposed at a substantially central position in the left-right direction of each upper end surface 507H and lower end surface 507L corresponding to each convex portion 518.

  The front-rear width dimension L2 of the upper end surface 507H and the front-rear width dimension L4 of the light emitting surface 62c are substantially the same (L2≈L4), and there is no deviation in the front-rear direction between the light emitting surface 62c and the upper end surface 507H. Light emitted from the light emitting surface 62c is incident on the upper end surface 507H without being diffused in the front-rear direction. Further, the front-rear width dimension L3 of the upper end surface 505H is substantially the same as the front-rear width dimension L1 near the lowest part of the lower end surface 507L (L3≈L1), and the deviation in the front-rear direction between the upper end surface 505H and the lower end surface 507L is As a result, the light emitted from the lower end surface 507L is incident on the upper end surface 505H without being diffused in the front-rear direction.

  Further, a predetermined gap (for example, about 1 to 3 mm) is provided between the lowermost portion of the lower end surface 507L and the upper end surface 505H and between the upper end surface 507H and the light emitting surface 62c of the display LEDs 62a and 62b. It is done. Thereby, the condensing lens 507 and the light guide plate 505 are prevented from being damaged by vibration generated when the gaming machine is transported or used.

  Next, the light guide state of the emitted light from the display LEDs 62a and 62b will be described.

  The outgoing light emitted from each of the display LEDs 62a and 62b enters the upper end surface 507H of the condenser lens 507. Here, since the front-rear width dimension L2 of the upper end surface 507H and the front-rear width dimension L4 of the light emitting surface 62c are substantially the same dimension (L2≈L4), the emitted light from the display LEDs 62a, 62b diffuses in the front-rear direction. Without being incident on the upper end surface 507H. Further, since the left and right width of the upper end surface 507H is longer than the left and right width of the light emitting surface 62c, the light diffused in the left and right direction is substantially incident on the upper end surface 507H.

  Incident light that enters the condenser lens 507 from the upper end surface 507H is guided toward the light guide plate 505 below. Although the LED light has high directivity, the incident light is diffused radially in the left-right direction by being incident through the upper end surface 507H formed in a curved shape so as to form a lens surface. Similarly, when passing through the lower end surface 507L formed as a curved lens surface, the light is refracted and emitted downward vertically (see FIG. 14).

  As a result, the light emitted from the display LEDs 62a and 62b having high directivity can be diffused radially to some extent in the left and right directions by the condenser lens 507 to widen the light emitting region, and the left and right directions on the lower end surface 507L can be expanded. Since light emitted from different positions is guided vertically downward and does not spread radially, only the vertically downward regions corresponding to the display LEDs 62a and 62b can be caused to partially emit light.

  Further, the incident light that has entered the condenser lens 507 from the upper end surface 507H is guided toward the lower light guide plate 505, and repeatedly undergoes total reflection in the front-rear (plate thickness) direction. (See FIG. 13), and finally exits from the lower end surface 507L having a shorter front-rear width than the upper end surface 507H.

  In this way, the light from the display LEDs 62a and 62b can be collected without being diffused in the front-rear width (plate thickness) direction and guided to the upper end surface 505H of the light guide plate 505, so that attenuation of light is suppressed. . In particular, even when the front-rear width dimension L4 of the light emitting surface 62c of the display LEDs 62a, 62b is larger than the front-rear width dimension L3 of the upper end surface 505H (L4> L3), the light from the display LEDs 62a, 62b is front-rear. Since the light can be guided to the upper end surface 505H of the light guide plate 505 without being diffused in the width (plate thickness) direction, the light from the display LEDs 62a and 62b is prevented from being diffused to the surroundings.

  Although not specifically shown, for example, even when a plurality of display LEDs 62a and 62b are arranged in the front-rear width direction, the front-rear width dimension L2 of the upper end surface 507H is expanded according to the display LEDs 62a and 62b, thereby Without being diffused into the upper end surface 507H. Therefore, even when the front and rear width dimension of the light emitting area of the display LEDs 62a and 62b is larger than the front and rear width dimension L3 (plate thickness) of the light guide plate 505, the light emitted from the display LEDs 62a and 62b is guided in the thickness direction while guiding the emitted light. The light can be condensed and incident on the light guide plate 505.

  The light emitted from the lower end surface 507L enters the upper end surface 505H of the light guide plate 505, and is guided downward while repeating total reflection by the front and rear surfaces. And when it reaches | attains reflection part 510a-510c, 511a-511c, incident light is reflected toward the front side by the reflective surface formed of the recessed part, and from a player, each reflection part 510a is reflected. The portions corresponding to ˜510c and 511a to 511c are emitted by reflected light, so that display information such as predetermined characters and characters is displayed.

  Next, an example of display control of the display device 500 performed by the sub CPU 91a will be described with reference to FIGS.

  In the present embodiment, during normal times, the sub CPU 91 a turns off the display LEDs 62 a and 62 b and performs a predetermined effect on the display screen 51 a of the liquid crystal display 51. Thus, in a state where the display LEDs 62a and 62b are turned off, the dot patterns constituting the reflecting portions 510a to 510c and 511a to 511c are not conspicuous, and thus are difficult for the player to visually recognize.

  The sub CPU 91a individually controls the display LEDs 62a and 62b respectively corresponding to the reflecting portions 510a to 510c of the front light guide plate 505a and the reflecting portions 511a to 511c of the rear light guide plate 505b, for example, in a notice effect or a bonus effect. Thus, the display information can be individually displayed in the left display area L, the middle display area C, and the right display area R of the light guide plate 505.

  Hereinafter, an example of the notice effect by the display device 500 will be described.

  For example, as shown in FIG. 15, a plurality of (for example, six) display LEDs 62a corresponding to the left display area L of the front light guide plate 505a are turned on in response to an operation of the left stop switch 8L, thereby causing the letters “large”. Is displayed (see FIG. 15A), and a plurality of (for example, six) display LEDs 62a corresponding to the middle display area C of the front light guide plate 505a are turned on in response to the operation of the middle stop switch 8C. Is displayed (see FIG. 15B), and a plurality of (for example, six) display LEDs 62a corresponding to the right display region R of the front light guide plate 505a are turned on according to the operation of the right stop switch 8R. The character “RI” is displayed (see FIG. 15C).

  Thus, predetermined display information can be displayed only in the display area corresponding to each stop switch in accordance with the stop operation of each stop switch 8L, 8C, 8R. In this case, the liquid crystal display 51 is turned off and the display screen 51a is black.

  FIG. 16 shows a display pattern using the front and rear light guide plates 505. Specifically, the letters “Large” are displayed by lighting a plurality of (for example, six) display LEDs 62a corresponding to the left display region L of the front light guide plate 505a in accordance with the operation of the left stop switch 8L ( In FIG. 16 (a)), a plurality of (for example, six) display LEDs 62a corresponding to the right display region R of the front light guide plate 505a are turned on in accordance with the operation of the middle stop switch 8C. Displayed (see FIG. 16B), and by turning on a plurality of (for example, six) display LEDs 62b corresponding to the middle display area C of the rear light guide plate 505b in accordance with the operation of the right stop switch 8R, “CHANCE” is displayed. ! "Is displayed (see FIG. 16C).

  As described above, the display CPUs 62a and 62b corresponding to the front and rear light guide plates 505 can be individually controlled by the sub CPU 91a, compared to the case where only the front and rear light guide plates 505 are displayed. , Display variations can be increased. That is, for example, the display LEDs 62a and 62b that are turned on in response to the operation of the stop switches 8L, 8C, and 8R are arbitrary, and thus display in various display patterns is possible.

  FIG. 17 shows a display pattern using the rear light guide plate 505 b and the liquid crystal display 51. Specifically, a drum character is displayed by turning on a plurality of (for example, six) display LEDs 62b corresponding to the left display area L of the rear light guide plate 505b in accordance with the operation of the left stop switch 8L (FIG. 17). (See (a)), a girl character is displayed by lighting a plurality of (for example, six) display LEDs 62b corresponding to the right display region R of the rear light guide plate 505b in accordance with the operation of the middle stop switch 8C ( In response to the operation of the right stop switch 8R, the characters “BONUS GET!” And the background are displayed on the display screen 51a of the liquid crystal display 51 (see FIG. 17C).

  In this way, not only the display LEDs 62a and 62b corresponding to the front and rear light guide plates 505 are individually controlled, but also the liquid crystal display 51 is simultaneously controlled to display one of the front and rear light guide plates 505, 505, Alternatively, display variations can be increased as compared with the case where the display is performed by the two front and rear light guide plates 505. That is, for example, the display LEDs 62a and 62b and the liquid crystal display 51 that are turned on in response to the operation of the stop switches 8L, 8C, and 8R are arbitrary, and therefore, it is possible to display in various display patterns.

  As described above, in the display device 500 provided in the slot machine 1 as the embodiment of the present invention, the display LEDs 62a and 62b are connected between the light guide plate 505 and the display LEDs 62a and 62b. The display LED 62a is provided by the provision of a condensing lens 507 that guides incident light to the light guide plate 505 side, condenses it in the thickness (front-rear) direction, and emits it toward the upper end surface 505H of the light guide plate 505. The light from the display LEDs 62a and 62b is guided to the upper end surface 505H of the light guide plate 505 without being diffused in the thickness direction by allowing the light from the light sources 62b to enter the light guide plate 505 through the condenser lens 507. As a result, the attenuation of light is suppressed, so that the visibility of display information such as characters and characters emitted by the reflectors 510a to 510c and 511a to 511c is improved.

  More specifically, the condensing lens 507 includes an upper end surface 507H disposed to face the display LEDs 62a and 62b, and a lower end surface 507L disposed to face the upper end surface 505H of the light guide plate 505. The lower end surface 507L is formed with a plate-like member, and the front-rear width dimension is shorter than the upper end surface 507H (L1 <L2), and the front surface 507F and the rear surface 507B are inclined in a direction gradually approaching each other from the upper end toward the lower end. By being a flat surface, the incident light incident from the upper end surface 507H can be condensed in the thickness direction while being guided by total reflection and emitted from the lower end surface 507L.

  In particular, when the front-rear width dimension L3 of the upper end surface 505H of the light guide plate 505 is shorter than the front-rear width dimension L4 of the light emitting surface 62c of the display LEDs 62a, 62b (L3 <L4), Even when the light quantity is increased by arranging a plurality of light sources in parallel, the incident surface of light emitted from a light source such as an LED can be increased according to the number of such light emitting surfaces and light sources. The emitted light from the display LEDs 62a and 62b can be incident on the upper end surface 505H of the light guide plate 505 without being diffused and attenuated.

  In addition, the light emitted from the display LEDs 62a and 62b is incident on the light guide plate 505 without diffusing to the surroundings in this way, so that the light of the display LED 62a corresponding to the front light guide plate 505a leaks and the light on the rear light guide plate 505b. The light does not enter the end surface 505H or the light of the display LED 62b corresponding to the rear light guide plate 505b leaks and does not enter the upper end surface 505H of the front light guide plate 505a. Therefore, it can be avoided that the light emitted from the display LEDs 62a and 62b corresponding to one of the light guide plates 505 in the front and rear leaks and enters the other upper end surface 505H and display information is displayed lightly. Further, the light emitted from the display LEDs 62a and 62b does not leak to the front side of the display screen 51a of the liquid crystal display 51 and the display screen 51a is not easily seen.

  Further, since the attenuation of the incident light from the display LEDs 62a and 62b is prevented in this way, the reflected light at the reflecting portions 510a to 510c and 511a to 511c is weakened, and the visibility of display information is not lowered. Therefore, since the concave and convex portions constituting the reflective portions 510a to 510c and 511a to 511c can be provided so as not to be noticeable as small as possible, for example, when the display LEDs 62a and 62b are turned off, the reflective portions 510a to 510c, The concavo-convex portions constituting 511a to 511c are conspicuous and do not give a sense of incongruity to the player.

  For example, the light guide plate 505 includes the front light guide plate 505a and the rear light guide plate 505b, so that the reflective portions 510a to 510c of the non-displayed front light guide plate 505a are configured when displaying on the rear light guide plate 505b. Therefore, the visibility of the rear light guide plate 505b is prevented from being impaired due to the concavity and convexity that are conspicuous.

  In addition, since the liquid crystal display 51 separate from the display device 500 is provided on the back side of the light guide plate 505, when the liquid crystal display 51 performs display, the non-display front light guide plate 505a is provided. It is possible to prevent the visibility of the display screen 51a from being impaired by the concavities and convexities that form the reflective portions 510a to 510c and the reflective portions 511a to 511c of the rear light guide plate 505b.

  Further, the front-rear width dimension L3 (plate thickness) of the light guide plate 505 can be made thin without being limited by the arrangement positions of the display LEDs 62a, 62b, the front-rear width dimension L4 of the light emitting surface 62c, and the like. Cost can be reduced.

  Furthermore, in the display device 500, since the display screen 51a of the liquid crystal display 51 is viewed through the two front and rear light guide plates 505, the thickness of the light guide plate 505, which is the front and rear width dimension L3, can be reduced. However, when the display screen 51a is viewed from a position slightly shifted to the left or right side from the front of the display screen 51a, the display image may be refracted due to the thickness of the light guide plate 505. If the thickness of the light guide plate 505 is made as thin as possible by providing the condenser lens 507 as described above, refraction can be suppressed as much as possible.

  In the above embodiment, the condensing lens 507 is formed in a horizontally long plate shape. However, the condensing lens 507 condenses the incident light from the display LEDs 62a and 62b toward the light guide plate 505 in the thickness (front and back) direction. The light guide plate 505 is not limited to a plate-like member as long as it can emit light toward the upper end surface 505H of the light guide plate 505. For example, as shown in FIG. 18, a dome capable of covering the display LEDs 62a and 62b A condensing lens 507 ′ made of a translucent member having a shape may be used.

  The condensing lens 507 'has a concave portion 507N capable of accommodating the display LEDs 62a and 62b on the upper end surface, and the inner surface of the concave portion 507N serves as an incident surface. The shape is a dome shape that tapers from the upper end to the lower end, and is configured to emit light from the lower end. Even in such a condensing lens 507 ′, the front-rear width dimension gradually becomes shorter from the upper end to the lower end, and the incident light is condensed in the front-rear direction while being guided to the light guide plate 505 side by total reflection and emitted. Can be made.

  In the condensing lens 507 of the above embodiment, the front surface 505F and the back surface 505B are flat inclined surfaces, respectively. However, if the light incident inside can be guided to the light guide plate 505 side, the condensing lens shown in FIG. You may comprise by the curved surface like optical lens 507 '.

  In addition, the convex portion 518 of the condenser lens 507 in the above embodiment is formed in a substantially semicircular shape when viewed from the front, and the lower end surface 507L is formed of a curved surface. However, light spreading in the left-right direction is directed vertically downward. Even if the shape is not semicircular as described above, for example, a trapezoidal shape can be variously changed as shown in FIG. Also, the lower end surface 507L does not necessarily have to be a curved surface.

  Moreover, in the said Example, reflection part 510a-510c, 511a-511c is provided in the back surface 505B of the light-guide plate 505, and the emitted light from LED 62a, 62b for display entered into the inside from the upper end surface 505H of the light-guide plate 505 is included. Is a reflective recess that reflects the light and emits it from the front surface 505F, but can emit display light from the front surface 505F by emitting incident light from the display LEDs 62a and 62b incident on the inside from the upper end surface 505H. If, for example, as shown in FIG. 20, the incident light from the display LEDs 62a and 62b incident on the inside from the upper end surface 505H of the light guide plate 505 is not totally reflected from the front surface 505F. It may be a light transmission guiding portion such as a plurality of convex portions 530 to be emitted, or is not particularly shown, but is formed on the front and rear surfaces. That instead of the concave or convex portion may be a reflection portion or the like formed on the light guide plate 505.

  Moreover, in the said Example, although the light guide plate 505 of the display apparatus 500 was comprised from the front light guide plate 505a and the rear light guide plate 505b, it is comprised from the 3 or more light guide plates 505 arrange | positioned in the front-back direction. Alternatively, only one light guide plate 505 may be configured.

  In the above-described embodiment, the front light guide plate 505a and the rear light guide plate 505b are spaced apart from each other with a predetermined gap, so that the output light reflected by the reflecting portions 511a to 511c on the back side is emitted to the front side. Although it is prevented that the light is reflected and reflected by the reflecting portions 510a to 510c of the front light guide plate 505a, they may be disposed in contact with each other.

  In the embodiment, the display LEDs 62a and 62b are provided so that light can enter the upper end surface 505H of the light guide plate 505. However, the display LEDs 62a and 62b may be provided so that light can enter the left and right end surfaces or lower end surfaces. Furthermore, the light source is not limited to the LED, and may be another light emitter such as a cold cathode tube.

  Moreover, in the said Example, although the light-emitting body was arrange | positioned only at one side of the light-guide plate 505, you may arrange | position a light-emitting body also on other sides, such as a left-right side or a lower side, for example. In this case, for example, if the reflection portion is provided so as to have a reflection surface that can reflect only incident light from the respective light emitters arranged on different sides to the front side, different display information may be obtained depending on the light emitter to be emitted. Can be displayed.

  In the embodiment, the display device 500 is disposed so as to be superimposed on the front side of the display screen 51a of the liquid crystal display 51 as an effect display device, and is integrated with each other to form the display unit 550. However, the display device 500 is not necessarily limited to the one disposed on the front side of such other display device (second display device). For example, the front surface of the reels 2L, 2C, and 2R is used. It may be arranged on the side or on the front side of a predetermined wall surface or a production member, etc., and may be configured to be used independently. Further, it can be installed at any location of the slot machine 1.
