(2) In the payout control board 24, as a solenoid driving power source such as a ball paying solenoid which plays a role of ball feeding inside the ball paying device L, a detection signal such as a DC 30V, 25 ball check SW and the like (LED DC12V is used as a display power source such as a rental LED), DC5V is used as a power source for IC circuits, and DC5V is used as a power source for RAM backup at the time of power failure.
(3) In the symbol display control board 29, DC12V is used as the power supply for the backlight and DC5V is used as the power supply for the IC circuit.
(4) The audio control board 20 uses DC 12V as a power source for outputting audio from the speaker and DC 5V as a power source for the IC circuit.
(5) In the lamp control board 31, 24V DC as a lamp display power source for side lamps, windmill lamps, attacker lamps, frame decoration lamps, etc., 12V DC for display power sources such as start winning memory number LEDs, prize ball LEDs, etc. and for IC circuits DC5V is used as the power source of the.
(6) In the launch control board 18, DC21.1V is used as a solenoid driving power source such as a ball feed solenoid for sending a ball to the hitting ball launching unit and a launch solenoid for hitting the hit ball, and the launch control board 18 is 24V AC from the power board 34. When the power supply is received, the power confirmation LED that lights up and DC12V are used as the power supply for the touch sensor IC circuit, and DC5V as the power supply for the IC circuit.
The IC circuit refers to CPU, ROM, RAM (storage means) and the like.

  That is, the power supply board 34 includes a first power generation circuit 74 that generates DC5V from AC24V, a second power generation circuit 75 that generates DC12V from AC24V, a third power generation circuit 76 that generates DC24V from AC24V, and a DC30V from AC24V. A fourth power generation circuit 77 for generating is provided, and power of different voltages generated by the circuits 74, 75, 76, 77 is supplied to the corresponding control boards 22, 31, 29, 20, 24, respectively. It has become. In the embodiment, the launch control board 18 includes a power generation circuit for generating power of different voltages used in the control board 18 and is supplied from the power board 34 via the power distribution board 27. A power supply of each voltage described above is generated from the power supply of AC24V by the power supply generation circuit. The ball rental unit K is supplied with AC 24V power necessary for communication from the power supply board 34 via the power distribution board 27 and the interface board 28.

  As shown in FIG. 13, a capacitor 78 (for example, an electric double layer type) is preferably used as backup means for backing up at least the RAM disposed on the main control board 22 and the payout control board 24. However, other types can also be used). When the main power supply is no longer supplied to the power supply board 34 due to a power-off state such as when the store is closed or a power failure occurs, the capacitor 78 is connected to the RAM of the main control board 22 and the RAM of the payout control board 24. Each RAM is backed up by supplying backup power, and the information stored in the RAM can be held for a predetermined time (backup time). The backup time can be changed as appropriate by exchanging with a capacitor having a different capacity.

  The power supply board 34 is provided with a power-off monitoring circuit 79 for monitoring power-off, and when the preset monitoring power supply becomes a certain voltage or less, the main control board 22 and the payout control board 24 are controlled. The power-off signal for switching from normal control to power-off control is set to be output. When the main control board 22 and the payout control board 24 receive the power-off signal, the main control board 22 and the payout control board 24 execute processing necessary for backup (power-off processing). In the embodiment, a power supply of DC30V for driving a solenoid is monitored as a monitoring power supply, and the voltage of the monitoring power supply is about DC20V or less (a power failure detection) which is a minimum voltage at which the solenoid operates without causing trouble in normal games. The power-off signal is set to be output when the voltage is reached.

Here, the power-off process by the power-off control in the main control board 22 is as follows.
A register and a stack pointer are stored in the RAM as backup data.
Turn off normal symbol output.
The output of the solenoid for opening / closing the start winning opening (ordinary electric accessory), the solenoid for opening / closing the large winning opening, and the path switching solenoid inside the large winning opening is turned OFF.
A command for turning off when the power is cut off is transmitted to the lamp control board 31 (all the lamps and LEDs that have been turned on and blinking are turned off).
A silent command is transmitted to the voice control board 20 (the voice that has been output is stopped).
When the ball dispensing device L is in operation (during the input process of the prize ball counting sensor (confirming the dispensed ball) provided in the ball dispensing device L), the power is cut off, and the balls dispensed are not counted. A process for preventing detection twice is performed.
Set a backup flag (when power is restored, check whether there is any abnormality in the backup data based on this flag).
Access to the RAM is prohibited.
After completion of the above processing, the CPU stands by in a state where the CPU can be stopped (CPU power supply stop standby state) (waiting for the power supply to the CPU to be interrupted while the program is looped).
Note that power recovery means that the voltage has reached a normal voltage when the power switch 66 is switched from OFF to ON, after a power failure, or at a momentary power interruption described later.

The power-off process by the power-off control in the payout control board 24 is as follows.
A register and a stack pointer are stored in the RAM as backup data.
The output to the prize ball solenoid and the ball lending solenoid provided in the ball payout device L is turned OFF so that a new payout operation is not performed.
The output of the error display unit 83 is turned off.
The control command transmitted from the main control board 22 is stored in the RAM as backup data.
When the ball dispensing device L is in operation (during the input process of the prize ball counting sensor (confirming the dispensed ball) provided in the ball dispensing device L), the power is cut off, and the balls dispensed are not counted. A process for preventing detection twice is performed.
Set a backup flag (when power is restored, check whether there is any abnormality in the backup data based on this flag).
Access to the RAM is prohibited.
After completion of the above processing, the CPU stands by in a state where the CPU can be stopped (CPU power supply stop standby state) (waiting for the power supply to the CPU to be interrupted while the program is looped).
The error display unit 83 is disposed in the vicinity of the payout control board 24, and displays according to the type of error, such as failure of the payout device L or full notification.

  The power supply board 34 is provided with a reset signal circuit 80, and after the power cut-off signal is output from the power cut-off monitoring circuit 79 (normally after a complete power failure and after the voltage drops for a moment from the power failure detection voltage) When the power switch 66 is switched from OFF to ON, the main control board 22, the payout control board 24, the symbol display control board 29, the voice control board 20, and the lamp control board 31 are switched on. On the other hand, it is set to output (ON) a reset signal for operating each CPU from the initial state (performing CPU security check and CPU initial setting and starting the program from address 0000). The reset signal output after the power-off signal is output is the time required for the backup processing of the main control board 22 and the payout control board 24 started by the power-off signal after the power-off signal is output. Is set to be output (ON) after a lapse of time and turned OFF after a predetermined time. The reset signal that is output when the power switch 66 is switched from OFF to ON or at the time of recovery after a power failure rises at the same time as the power supply rises, and a predetermined voltage (for example, a power failure detection voltage or a preset reset voltage) ) Is set to be turned off after a predetermined time with reference to the point in time. Each control board 22, 24, 29, 20, 31 initializes each CPU when the reset signal input via the reset input circuit 84 shown in FIG. 13 changes from ON to OFF (at the fall). A reset process that starts from the state is executed.

  The reset signals are input to the control boards 22, 24, 29, 20, 31 at the same time, and the timing of the reset signals to the control boards 22, 24, 29, 20, 31 is shifted. The control board which cannot receive the signal is prevented from being generated. It should be noted that when the power switch 66 is switched from OFF to ON or when the reset signal is output at the time of recovery after a power failure, the power failure is the minimum value at which the components receiving the monitoring power supply can operate. In the case of the detection voltage, since the reset process is performed after securing a minimum voltage at which the components can operate, the operation of each component can be reliably guaranteed.

  Here, the power-off monitoring circuit 79 transmits a power-off signal for causing the main control board 22 and the payout control board 24 to perform a backup operation when the monitoring power supply reaches the power failure detection voltage as described above. The main control board 22 and the payout control board 24 that have received the power-off signal perform backup processing (power-off processing) and wait in a state where the CPU can be stopped. However, when the voltage of the main power supplied to the pachinko machine P drops for a moment due to some cause (effect of noise, etc.), and the voltage returns to normal without the pachinko machine P completely stopping (during momentary power interruption) The main control board 22 and the payout control board 24 that have received the power-off signal are in a state of waiting for the operation of the CPU to be stopped when the power is turned off after finishing the backup process. In addition, the CPU of the payout control board 24 has a disadvantage that the processing is not performed in a standby state for stopping. The voice control board 20 that has received a silent command from the main control board 22 during the power-off process of the main control board 22 does not receive a new signal from the main control board 22 even when the voltage returns to normal. The lamp control board 31 that has continued the state and has received a command for turning off when the power is turned off does not receive a new signal from the main control board 22 even when the voltage returns to normal. The inconvenience of continuing the light-off state occurs. However, in the embodiment, if the reset signal is output after the power-off signal is output and the voltage returns to normal again after the momentary power failure, the CPU of the main control board 22 or the payout control board 24 performs reset processing (CPU The above-described inconvenience does not occur because the security check and the CPU initial setting are performed and the program is started from the address 0000.

  The power supply board 34 is provided with a RAM clear switch (clear switch) 69 for simultaneously initializing (clearing) the RAM as the storage means of the main control board 22 and the RAM as the storage means of the payout control board 24. The clear switch 69 extends rearward through a RAM clear switch through hole 70a formed in the housing case body 43, and can be turned on and off with a fingertip from the outside. In the RAM clear switch circuit (clear switch circuit) 82 provided on the power supply board 34, only when the power switch 66 is turned on while the RAM clear switch 69 is turned on, both control boards 22 and 24 are connected. On the other hand, it is set to output a clear switch signal for initializing the RAM (see FIG. 14). That is, in the embodiment, the RAM clear switch 69, the RAM clear switch circuit 82, and the power switch 66 constitute the clear means for the storage means, and when the stored information at the time of factory shipment and the stored information at the time of closing the store are erased, The clear means for the storage means is preferably used. Note that the RAM clear switch 69 of the embodiment is always held in the OFF state by an elastic means (not shown), and when the switch 69 is turned on by the fingertip operation and then released, it automatically returns to the original OFF state. Configured to return.

(Effects of Example)
Next, the operation of the pachinko gaming machine according to the present embodiment configured as described above will be described.

  In the pachinko machine P of the present embodiment, the mounting base body 42 is connected to the mounting portion 40 of the back cover member 33 that covers and protects the back side of the symbol display device 15, the locking holes 40a, the pins 40b, the locking pieces. In addition to positioning through the positioning holes 42a and the positioning holes 42b, the screws 54 inserted into the through holes 42c are respectively screwed into the corresponding screw holes 40c to be positioned and fixed. Further, the cover body 51 is assembled to the case body 43 through the engagement protrusions 57 and the engagement holes 71 in a state where the power supply board 34 is set on the bottom plate portion 43 a of the housing case body 43. Thus, the power supply device 35 in which the power supply board 34 is accommodated and set in the accommodation box 52 is configured as a box-type unit. The housing case body 43 is opposed to the mounting base body 42, and the housing box body 52 is slid in the lateral direction in a state where the engaged piece 56 is adjacent to the engaging piece 55. The housing box 52 is positioned on the mounting base by the engagement between the engagement piece 55 and the engagement piece 56. At this time, the locking hook 44 provided on the installation portion 40 engages with the right end edge portion of the housing case body 43 by elastic deformation, whereby the power supply device 35 is positioned and held on the back cover member 33. .

  Since the power supply device 35 can be attached to and detached from the back cover member 33 without using a fixing means such as a tool or a screw, maintenance of the device 35 and replacement of the power supply board 34 can be easily performed. In addition, with the power supply device 35 disposed on the back cover member 33, as shown in FIG. 5, the rear surfaces of both 33 and 35 are set so as to face substantially the same surface. It does not protrude greatly.

  As described above, the main control board 22, the payout control board 24, the symbol display control board 29, the voice control board 20, the lamp control board 31, and the power supply are provided on the power supply board 34 of the power supply device 35 attached to the back cover member 33. Distribution boards 27 are connected to each other through power supply wiring. The power distribution board 27 is connected to the launch control board 18 and the interface board 28 via power wiring. In this case, as shown in FIG. 1, the power supply board 34 is located substantially at the center of the back surface of the pachinko machine P, and is connected to the power supply board 34 via power supply wiring, the payout control board 24, the design. Since the display control board 29, the sound control board 20, the lamp control board 31 and the power distribution board 27 are arranged around the power board 34, the power board 34 and the boards 22, 24, 29, 20, The length of the power supply wiring connecting the terminals 31 and 27 can be shortened, so that the wiring process becomes easy and it is difficult to be affected by noise. Further, since the length of the power supply wiring between the substrates is shortened, it is possible to prevent an unauthorized substrate from being attached in the middle and to discover an unauthorized substrate at an early stage.

  In the embodiment, a back cover member 33 is provided on the back side of the back set member 13, and the symbol display control board 29 and the lamp control board 31 provided on the set member 13 are covered with the back cover member 33. However, since the power supply board 34 is arranged on the lower side of the back cover member 33 and the lead-out port 45 for electrical wiring is formed at the lower end portion of the cover member 33, both control boards 29, By pulling out the power supply wiring derived from 31 from the lead-out port 45, it is possible to connect to the power supply board 34 at the shortest distance. In addition, since the connectors 60 and 62 for connecting the power supply wirings of the symbol display control board 29 and the lamp control board 31 to the power supply board 34 are provided in the lower part of the power supply board 34, the power supply wiring is also routed by this. The length can be shortened. Further, connectors 58, 61, 59, 63 for connecting power wirings of the main control board 22, the dispensing control board 24, the voice control board 20, and the power distribution board 27 arranged below the power board 34 are also the connectors. Since it is provided in the lower part of the power supply board 34 like 60 and 62, the length for routing these power supply wirings is also shortened. In addition, since all the connectors 58, 62, 60, 61, 59, 63 are arranged and exposed, workability at the time of connecting / disconnecting power supply wiring is improved and connected. Since the wiring can be easily understood, it is possible to prevent unauthorized board mounting.

  Since the power supply device 35 (power supply board 34) provided on the back cover member 33 is located at a substantially central portion on the back side of the pachinko machine P, a power switch 66 provided on the power supply board 34 in the game hall. In addition, the RAM clear switch 69 can be easily operated. Further, the back cover member 33 is the part that protrudes most on the back side of the pachinko machine P, and a high heat dissipation effect can be obtained by arranging the power supply substrate 34 on the member 33. Furthermore, although the ball storage / discharge route portion 16 is a portion where a lot of noise is generated, since the power supply board 34 is separated from the route portion 16, it is possible to suppress the influence of noise. The back cover member 33 functions to protect the symbol display device 15 and various substrates. However, the lower cover member 33 has a space in the space just by facing parts such as an attacker. Has not been used effectively. However, in the embodiment, the installation unit 40 is provided in this portion and the power supply device 35 (power supply board 34) is provided, so that the space can be effectively used.

  Further, since the power supply board 34 is disposed on the back cover member 33, all the boards (wirings) disposed on the pachinko machine P can be confirmed simultaneously by simply opening the back cover member 33. . Further, since the back cover member 33 can be opened with the power supply device 35 with one touch, the substrates covered with the cover member 33 (substrates 30 and 31 disposed on the back set member 13). , 32, etc.) can be easily confirmed, and there is no need to remove or attach another board for board confirmation.

  In the embodiment, when the back of the gaming machine is viewed, when the back cover member 33 is opened, at least the CPU (ROM) of the main control board 22 and the payout control board 24 is removed without removing each control board. Each control board is arranged so that it can be confirmed (see FIG. 1). That is, an unauthorized CPU (ROM) can be found at an early stage without removing each control board.

  The power supply board 34 is supplied with an AC24V original power supply from an external power supply, and a plurality of power supplies (DC5V, DC12V, DC24V, DC30V) having different voltages from the original power supply by the respective power generation circuits 74, 75, 76, 77. Is generated, and each power source is supplied to the corresponding control board 22, 24, 29, 20, 31 (see FIG. 12). The launch control board 18 is supplied with AC 24V from the power board 34 through the power distribution board 27 as it is, and a power source of a necessary voltage is generated by a power generation circuit provided on the control board 18.

  That is, since the power supply board 34 collectively generates a plurality of power supplies having different voltages used by the control boards 22, 24, 29, 20, and 31, it is necessary to provide a power generation circuit for each control board. In addition, each control board 22, 24, 29, 20, 31 can be downsized and the cost can be reduced. In the embodiment, the launch control board 18 has its own power generation circuit, but at least the main control board 22 and a payout control board 24 directly connected to the main control board 22, a symbol display control board 29, The board to be replaced when the game board J such as the sound control board 20 and the lamp control board 31 is replaced is not provided with a power generation circuit, which greatly contributes to cost reduction. Furthermore, since the power supply voltage (DC5V) for driving the IC circuit disposed on each control board 22, 24, 29, 20, 31 is also collectively generated by the power supply board 34, each control board 22, 24 is generated. , 29, 20, 31 does not cause an error in the power supply voltage for driving the IC circuit, and the transmission / reception of signals between the main control board 22 and the other control boards 24, 29, 20, 31 is hindered. It is possible to preferably prevent the circuit or the circuit itself from being damaged. As described above, the launch control board 18 is connected to the payout control board 24 (the launch control board 18 receives the launch stop signal from the payout control board 24 when the ball lending unit K is not connected to the interface board 28. And is not connected to the main control board 22, so that even if the launch control board 18 independently generates the power supply voltage for driving the IC circuit, it is inconvenient for launch control. There is no risk of occurrence. Further, since the launch control board 18 is a component that is used in common regardless of the exchange of the game board J, even if it has a power generation circuit, there is no cost effect.

  In the pachinko machine P, when the original power is not supplied to the power supply board 34 due to a power failure or the like (when the power supply is cut off), the RAM 78 and the payout control board of the main control board 22 are connected from the capacitor 78 to the power supply board 34. Backup power is supplied to the 24 RAMs, and information relating to the game when the power is turned off is stored and held in both RAMs. (1) Even if a power failure occurs during a special game state such as a big hit or a probability fluctuation state, the game can be resumed at the time of power recovery, or the rental or prize ball has not been paid out The state of the number can be maintained and the payout can be made accurately at the time of power recovery, and there is no disadvantage to the player. In the pachinko machine P of the embodiment, even when the power switch 66 is turned off due to closing or the like, backup power is supplied from the capacitor 78 to the RAM of the main control board 22 and the RAM of the payout control board 24. Therefore, (2) the memory that has been in a state of probability variation when the store is closed can be carried over to the next morning, or (3) information on the number of unpaid balls or prize balls can be held.

  Further, a capacitor 78 for supplying backup power is provided on the power supply board 34, and the backup power is supplied on the same connector (wiring) as the normal power supply. However, there is no increase in the number of other boards, wirings, etc., the increase in the number of parts and the number of assembly steps can be prevented, and the cost can be kept low. In addition, since there is one capacitor 78, there is no possibility of causing an error in the backup time during which the backup power is supplied to the RAM of the main control board 22 and the RAM of the payout control board 24. In other words, if an error occurs in the backup time (storage time) of both RAMs, for example, information stored in the main control board 22 is not stored in the payout control board 24, causing a problem in control during power recovery. There is a possibility that such inconvenience is prevented. Therefore, there is no disadvantage to the player.

  Next, in the pachinko machine P, when the monitoring power supply becomes a certain voltage or less, the power-off monitoring circuit 79 switches the normal control from the power-off control to the main control board 22 and the payout control board 24. Power off signal is output. When receiving the power-off signal, the main control board 22 and the payout control board 24 execute the above-described processing necessary for backup. That is, at the time of voltage drop that would impede the game, the main control board 22 and the payout control board 24 perform the above-described backup processing, so that there is no disadvantage to the player.

  The power-off monitoring circuit 79 is set to output a power-off signal when the monitoring power reaches the minimum power failure detection voltage at which the solenoid operates without causing a problem in normal games as described above. It is. That is, when the power-off signal is output, the solenoid driven by the highest voltage in the pachinko machine P is normally operating, so all other electrical devices are also operating normally, and the operating devices And devices that have already become inoperable are not mixed. Therefore, by performing the backup process at this time, there is no discrepancy between the information at the time of backup processing of the main control board 22 and the payout control board 24, and normal operation at the time of power recovery is guaranteed. In addition, since all the CPUs are in the power-off standby state before the power supply is stopped by the power-off process described above, it is possible to prevent the CPU itself and the program from malfunctioning due to the power supply stop.

  Further, after a power-off signal is output from the power-off monitoring circuit 79, a reset process (reset signal is activated) when the power is restored at each control board 22, 24, 29, 20, 31. At the time of falling, a reset signal for performing a security check of the CPU and initial setting of the CPU and starting a program from address 0000) is sent from the reset signal circuit 80 to the control boards 22, 24, 29, 20, 31 is output. That is, normal operation of the CPU at the time of power recovery when the voltage returns to normal after a power failure is guaranteed. Further, in the power supply board 24 of the embodiment, the power cut-off signal and the reset signal are output in any case of normal power OFF, power failure, and instantaneous power failure. When power supply is started (when power is restored), normal operation of the CPU can be guaranteed.

  As described above, since the power-off monitoring circuit 79 and the reset signal circuit 80 are commonly used for all target control boards, the power-off signal and the reset signal are simultaneously output to the control boards. The timing of each process for each control board can be matched. That is, it is possible to prevent the occurrence of defects due to the timing shift of each process for each control board. In addition, since the power-off monitoring circuit 79 and the reset signal circuit 80 are provided only on the power supply board 34, there is no waste of separately providing a circuit other than each control board or power supply board, and the cost can be kept low. Can do. It is possible to determine that there is a problem with the entire gaming machine by detecting an abnormality in the voltage drop by the power-off monitoring circuit 79 provided on the power supply board 34.

  In the pachinko machine P, when erasing factory inspection information and closing information stored in the RAM of the main control board 22 and the RAM of the payout control board 24, the power supply board 34 is provided. When the power supply switch 66 is turned on while the RAM clear switch 69 is turned on, a clear switch signal for initializing both RAMs for the main control board 22 and the payout control board 24 is RAM cleared. The information output from the switch circuit 82 and stored in each RAM is erased. In this case, the RAM clear switch circuit 82 is set to output the clear switch signal only when the power switch 66 is turned on while the RAM clear switch 69 is kept on. Can be prevented from being initialized. In addition, malfunction due to generation of noise can be suppressed. Further, since the RAM of the main control board 22 and the RAM of the payout control board 24 are initialized simultaneously by operating one RAM clear switch 69, the RAM clear processing is simultaneously performed on both the control boards 22 and 24, and the timing thereof. It is prevented that the control is disturbed due to the deviation.

  Here, the pachinko machine P of the embodiment is provided with a winning detection SW at every winning opening, and when the main control board 22 detects a winning signal from each winning opening SW, the number of winning balls corresponding to the winning opening Are stored in the RAM and managed as the total number of prize balls for the main control board, and a prize ball control command corresponding to the number of prize balls is created and transmitted to the payout control board 24. The total number of winning balls for the main control board is added to the number of winning balls each time a winning opening is won, and a winning ball counting sensor signal (an input detected every time a winning ball provided in the ball paying device L is paid out). Each time (signal) is detected, subtraction is performed from the total number of main control board prize balls. On the other hand, when the payout control board 24 receives a prize ball control command from the main control board 22, it stores the number of prize balls corresponding to the prize ball control command in the RAM and manages it as the total number of prize balls for the payout control board. . The payout control board 24 controls the ball payout device L to pay out one by one, detects an input signal of a prize ball counting sensor in the ball payout apparatus, and −1 from the total number of payout control board prize balls. Subtraction is performed, and the payout operation is performed until the stored total number of payout control board prize balls becomes zero.

  Therefore, when the timing of the RAM clear processing is shifted, for example, when the total number of prize balls for the main control board and the total number of prize balls for the payout control board is 10, the timing of the RAM clear process is shifted. As a result, only the total number of main control board prize balls is erased and the total number of payout control board prize balls is not erased. In this state, the ball payout device L operates (the payout control board 24 is a payout control board). The payout operation is executed until the total number of prize balls reaches 0), and the total number of prize balls for the main control board becomes negative. For this reason, the main control board 22 recognizes an excessive payout state due to a failure of the ball payout device L, etc., because the total number of the main control board prize balls becomes negative, and performs error notification and stops payout. There is a problem that the game stops. However, in the embodiment, since the timing of the RAM clear process is not shifted, the above-described problem does not occur.

  If the power supply wiring connector for supplying backup power to the RAM of the main control board 22 and the RAM of the payout control board 24 is removed from the capacitor 78 of the power supply board 34, the clear means for the storage means is used. Although it is possible to initialize both RAMs even if not, the attaching / detaching operation of the connector is complicated, and if the connector is attached / detached frequently, the connector may be damaged. In addition, two connectors must be attached and detached, but if one forgets to remove one of the connectors, the above-described problems are caused, which is not practical.

[Example of change]
In the embodiment, when the power supply board generates a plurality of power supplies having different voltages used in the main control board and the payout control board, the symbol display control board, the voice control board, and the lamp control board that are directly connected to the main control board. As described above, a plurality of power sources having different voltages including a power source voltage for an IC circuit used in a launch control board for controlling the hitting ball launching device (component) are also generated by the power board (from AC24V to solenoids). It is also possible to add a power generation circuit that generates DC 21.1 V used as a power source for In this case, the launch control board is connected to the power board without going through the power distribution board, but since the launch control board is also arranged around the power board like the other control boards, both are connected. The length of the power supply wiring is short and the influence of noise is reduced. The power supply generated by the power supply board may be any power supply that can be used for at least the main control board, the symbol display control board, the voice control board, and the lamp control board that are exchanged when the game board is exchanged. Each of the launch control boards may include a power generation circuit. In other words, since all control boards that are exchanged together with the game board do not need to have a power generation circuit, the recyclability after replacement is improved and the generation circuit that is wasted is eliminated, so that environmental problems are also addressed. Have the advantage. Note that the number of power generation circuits provided on the power supply board can be changed depending on the number of power supplies to be generated, and the voltage of the power supply to be generated is not limited to the embodiment. Any necessary voltage may be used.

  The configuration in which the power supply device is detachably disposed on the back cover member is not limited to the embodiment. For example, the back cover member, the first locking means and the first locked means in the mounting base are provided. The configuration opposite to that of the embodiment can be adopted. Further, the mounting base can be mounted by an engaging means using a hole and a protrusion instead of being fixed with a screw. Further, the second engaging means and the second engaged means in the housing case body and the cover body constituting the housing box can be configured opposite to those in the embodiment, or can be elastically deformed provided on one member. A configuration in which a simple engagement hook is used may be employed. Note that the mounting means (first engaging means and first engaged means) of the storage box relative to the mounting base is not limited to the configuration of being engaged / disengaged by sliding as in the embodiment, and holes, hooks, etc. are used. Thus, other configurations such as a method of attaching and detaching back and forth can be adopted. The back cover member may be disposed on the back mechanism set board. Furthermore, since the power supply board is a non-replaceable part when the game board is replaced, it is desirable that the power supply board is disposed on the non-replaceable part when the game board is replaced.

  In the embodiment, the case where the backup power is supplied from the capacitor to the RAM of the main control board and the RAM of the payout control board has been described. However, the stored information disappears when the power is turned off. Backup power may be supplied from the capacitor to the RAM (storage means). The backup means for supplying backup power to both RAMs is not limited to the capacitor of the embodiment, and other types can be adopted. One backup means means a plurality of RAM (such as one constituted by connecting a plurality of capacitors in series in addition to one capacitor, or one battery or a plurality of batteries arranged in series. Means for commonly supplying backup power to the storage means).

  In the embodiment, the RAM clear switch for initializing the RAM is disposed on the power supply board. However, the power switch (clearing means) that also functions as the RAM clear switch is a button type, and the power switch is long. The RAM clear switch circuit may be set to output a clear switch signal only when it is pressed. In this case, the clearing means for the storage means is constituted by the power switch and the RAM clear switch circuit. In addition, there are two types of switches: a switch that only turns on / off the power and a switch that can turn on / off the power and initialize the RAM (which together with the RAM clear switch circuit constitutes a clear means for the storage means). A configuration in which the power supply board is disposed may be employed. In this case, it is preferable to employ a configuration in which a switch that can turn on / off the power and initialize the RAM is covered with a cover member or the like to prevent erroneous operation of the switch. In the configuration of the modified example, the RAM can be initialized by a single operation in any case.

In the embodiment, a reset signal is simultaneously output from the reset signal circuit on the power supply board to the main control board, the payout control board, the symbol display control board, the voice control board, and the lamp control board, and the CPU on each control board is in the initial state. (The security check of the CPU and the initial setting of the CPU are performed and the program is started from the 0000 number). However, the security check and the initial setting time may vary depending on the individual difference and performance of the CPU on each control board. Considering the case where the control board cannot start receiving signals from the main control board because the main control board starts operation before the other control board due to variations, the following configuration may be adopted.
By providing a delay means (timer circuit) in the reset input circuit on each control board, for example, by delaying the input (falling) of the reset signal to the CPU on the main control board, the CPU on the other control board operates. It may be configured such that the CPU of the main control board starts from the initial state after reaching a possible state.
With this configuration, the reset signal transmission timing (ON, OFF) from the reset signal circuit on the power supply board to each control board is common to all control boards. It is also possible to start the initial state of the CPU of the other control board earlier than the CPU of the main control board by shifting the timing of transmitting the reset signal to the CPU by the input circuit.
