In this embodiment, a power supply of 30 V DC for driving a solenoid is monitored as a monitoring power supply, and the voltage of the monitoring power supply is about 20 V DC or less, which is the minimum voltage at which the solenoid operates without causing trouble in a normal game (power failure detection). Voltage), a power-off signal is set to be output.

Here, the power-off processing by the power-off control in the main control board 22 is as follows. Register and stack pointer RA as backup data
Store it in M. Normally, the output of the symbol is turned off. The output of the solenoid for opening and closing the winning opening (usually an electric accessory), the solenoid for opening and closing the winning opening, and the solenoid for switching the path inside the winning opening are turned off. A power-off command is transmitted to the lamp control board 31 (all of the lamps and LEDs that have been turned on and off are turned off). A silent command is transmitted to the voice control board 20 (the output voice is stopped). The power is cut off while the ball dispensing device L is being driven (during input processing of the prize ball counting sensor (confirming the dispensed ball) provided in the ball dispensing device L), and the dispensed ball is not counted. A process for preventing detection twice is performed. A backup flag is set (at the time of power recovery, it is confirmed whether there is any abnormality in the backup data based on this flag). Prohibits access to the RAM. After the above processing, the CPU waits in a state where the CPU can be stopped (CPU power stop standby state) (waiting for interruption of power supply to the CPU while the program is looping). The power recovery means that the voltage has reached the normal voltage when the power switch 66 is switched from OFF to ON, after a power failure, or at the time of an instantaneous power failure described later.

The power-off processing by the power-off control in the payout control board 24 is as follows. Register and stack pointer RA as backup data
Store it in M. 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. Error display section 8
3 is turned off. The control command transmitted from the main control board 22 is stored in the RAM as backup data. Ball dispensing device L is being driven (prize ball counting sensor provided in ball dispensing device L (confirms the dispensed ball)
The power is cut off during the input process of (1), and a process is performed to prevent the paid-out balls from being counted or detected twice. A backup flag is set (at the time of power recovery, it is confirmed whether there is any abnormality in the backup data based on this flag). Prohibits access to the RAM.
After the above processing, the CPU waits in a state where the CPU can be stopped (CPU power stop standby state) (waiting for interruption of power supply to the CPU while the program is looping). Note that the error display section 83 displays the payout control board 2
The display is provided in the vicinity of the dispensing device L and indicates a type of error, such as a failure of the dispensing device L or a full notification.

A reset signal circuit 80 is provided on the power supply board 34. After a power-off signal is output from the power-off monitoring circuit 79 (when a complete power failure occurs and the voltage drops momentarily below the power failure detection voltage). The main control board 22 and the payout control board 2
4. Operate each CPU in the symbol display control board 29, the voice control board 20, and the lamp control board 31 from the initial state (perform the security check of the CPU and the initial setting of the CPU, and start the program from the address 0000). Is set so as to output (ON) a reset signal for ON. Note that the reset signal output after the power-off signal is output, after the power-off signal is output,
It is set so that it is output (ON) after the time required for the backup process of the main control board 22 and the payout control board 24 started by the power-off signal and turned off after a predetermined time. Also, the reset signal output when the power switch 66 is switched from OFF to ON or when returning after a power failure, the reset signal 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, etc.) ) Is set to be turned off after a predetermined time from the point of time when). 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 (falling). A reset process for starting from a state is executed.

The control boards 22, 24, 29, 20, 31
The reset signals to the control boards 22, 24, 29, 20, and 31 are set so that the reset signals are input at the same time. It is configured to be prevented. Note that the reference of the output time of the reset signal output when the power switch 66 is switched from OFF to ON or at the time of recovery after a power failure is the minimum value of the power failure of the component receiving the monitoring power supply. When the detection voltage is used, since the reset process is performed after securing a minimum value voltage at which the components can operate, the operation of each component can be reliably guaranteed.

Here, the power-off monitoring circuit 79 generates a power-off signal for causing the main control board 22 and the dispensing control board 24 to perform a backup operation when the monitored power reaches the power failure detection voltage as described above. The main control board 22 and the payout control board 24 that have transmitted and received the power-off signal perform backup processing (power-off processing), and wait in a state where their CPUs can be stopped. However, some cause (such as the influence of noise)
When the voltage of the main power supply supplied to the pachinko machine P drops momentarily and the voltage returns to the normal state without completely stopping the pachinko machine P (at the time of an instantaneous stop), the main control receiving the power-off signal Since the board 22 and the dispensing control board 24 are in a standby state after the backup processing is completed and the operation of the CPU can be stopped by turning off the power, the main control board 22
In addition, there is an inconvenience that the CPU of the payout control board 24 does not perform the process in a standby state for stopping. Then, the main control board 22 is turned off when the power of the main control board 22 is turned off.
The voice control board 20, which has received a silent command from, does not receive a new signal from the main control board 22 even when the voltage returns to normal, so that the voice control board 20 continues the silent state, and also receives a power-off light-off command. Since the lamp control board 31 does not receive a new signal from the main control board 22 even when the voltage returns to normal, there is a problem that the lamp of the pachinko machine P or the like is kept turned off. However, in the embodiment, if the reset signal is output after the output of the power-off signal 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 the reset processing (CPU The security check and the initial setting of the CPU are performed to start the program from address 0000), so that the above-described inconvenience does not occur.

The power supply board 34 has a RAM for initializing the RAMs of the main control board 22 and the payout control board 24.
A RAM clear switch 69 as a RAM clear means is provided. The clear switch 69 extends rearward through a RAM clear switch through hole 70a formed in the housing case body 43, and is externally provided with a fingertip. It is configured to be operated with. Then, the RAM clear switch circuit 82 provided on the power supply board 34 turns on the power switch 66 while turning on the RAM clear switch 69.
RAM for both control boards 22 and 24 only when
Is set so as to output a clear switch signal for initializing (see FIG. 14). That is, the RAM clear switch 69 can be suitably used to erase the memory of the inspection at the time of factory shipment and the memory at the time of closing the store. Note that the RAM clear switch 69 of the embodiment is used.
Is always kept OFF by elastic means or the like (not shown), and the switch 69 is turned ON by a fingertip operation.
It is configured to automatically return to the original OFF state if released after switching to the state.

Next, the operation of the power supply board arrangement structure of the pachinko gaming machine according to the present embodiment having the above-described configuration will be described.

In the pachinko machine P of this embodiment, the mounting base 42 is attached to the installation portion 40 of the back cover member 33 for protecting the back side of the symbol display device 15 by the cover hole 40a, the pin 40b, Positioning is performed through the locking pieces 42a and the positioning holes 42b, and the respective through holes 42c
Are screwed into the corresponding screw holes 40c to fix and fix the position. When the power supply board 34 is set on the bottom plate 43a of the housing case 43, the cover 51 is assembled to the case 43 via the engagement protrusions 57 and the engagement holes 71. The power supply device 3 in which the power supply board 34 is set in the storage box 52
5 is configured as a box-type unit. Then, the housing case body 43 is opposed to the mounting base body 42, and the housing box body 52 is slid laterally in a state where the engaged piece 56 is adjacent to the engaging piece 55,
The storage box 52 is engaged with the engagement piece 55 and the engaged piece 56.
Is positioned on the mounting base. At this time, the locking hook 44 provided on the installation portion 40 is engaged with the right edge of the housing case 43 by elastic deformation, whereby the power supply device 35 is positioned and held on the back cover member 33. .

Since the power supply unit 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 unit 35 and replacement of the power supply board 34 can be easily performed. Can be. In a state where the power supply device 35 is disposed on the back cover member 33, as shown in FIG. 5, the rear surfaces of the both 33, 35 are set to be substantially in the same plane, and the power supply device 35 is located on the back side of the gaming machine. Does not protrude significantly.

As described above, the power supply board 34 of the power supply unit 35 attached to the back cover member 33 includes 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. The power supply board 31 and the power distribution board 27 are connected to each other via power supply wiring. The power distribution board 27 is connected to the emission 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 a power supply wiring. Since the display control board 29, the audio control board 20, the lamp control board 31, and the power distribution board 27 are collectively disposed around the power supply board 34, the power supply board 3
The length of the power supply wiring connecting the substrate 4 to each of the substrates 22, 24, 29, 20, 31, 27 can be shortened, so that the wiring processing is facilitated and the influence of noise is reduced. Also,
Since the length of the power supply wiring between the boards is shortened, it is possible to prevent an incorrect board from being mounted on the way, and to detect the incorrect board 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 formed by the back cover member 33. Although the power supply board 34 is disposed below the back cover member 33 and the outlet 45 for electrical wiring is formed at the lower end of the cover member 33, Substrate 29,3
By pulling out the power supply wire derived from 1 through the outlet 45, the power supply wiring can be connected to the power supply board 34 with the shortest distance.
Moreover, the connectors 60 and 62 for connecting the power supply wiring of the symbol display control board 29 and the lamp control board 31 to the power supply board 34 are provided below the power supply board 34. Can be shortened. Further, the main control board 22 and the payout control board 2 which are arranged below the power supply board 34.
4. The connectors 58, 61, 59 and 63 for connecting the power supply wiring of the audio control board 20 and the power distribution board 27 are also provided below the power supply board 34 like the connectors 60 and 62. The length of handling is also reduced. All the connectors 58, 62, 60, 61, 5
Since 9,63 are arranged and exposed together,
The workability in connecting and removing the power supply wiring is improved, and the connected wiring can be easily identified, so that it is possible to prevent improper mounting of the board.

The power supply device 35 (power supply board 34) disposed on the back cover member 33 is located substantially at the center on the back side of the pachinko machine P.
The operation of the power switch 66 and the RAM clear switch 69 provided in the device 4 becomes easy. Also, the back cover member 33
Is the most protruding part on the back side of the pachinko machine P, and by disposing the power supply board 34 on the member 33, a high heat radiation effect can be obtained. Further, the sphere storage / discharge path section 16 is a part where a lot of noise is generated.
Is separated from the path section 16, so that the influence of noise can be reduced. The back cover member 3
Reference numeral 3 denotes a portion which functions to protect the symbol display device 15 and various substrates, but has a space in the lower side just because a component such as an attacker faces, and conventionally, this portion is effectively used. Was not done. But,
In the embodiment, the installation section 40 is provided in this portion, and the power supply 35
Since the (power supply board 34) is provided, the space can be effectively used.

A power supply board 34 is provided on the back cover member 33.
, All the boards (wirings) provided in the pachinko machine P can be checked at the same time simply by opening the back cover member 33. Further, the back cover member 33
Is configured so that it can be opened with one touch together with the power supply device 35, so that the substrate covered by the cover member 33 (the substrates 30, 3 disposed on the back set member 13)
1, 32, etc.) can be easily checked, and it is not necessary to remove or attach another board to check the board.

In the embodiment, when the back cover member 33 is opened when the back of the gaming machine is viewed,
Without removing each control board, at least the main control board 2
Each control board is arranged so that the CPU (ROM) of the payout control board 2 and the payout control board 24 can be checked (FIG. 1).
reference). That is, an unauthorized CPU (ROM) can be found at an early stage without removing each control board.

The power supply board 34 has an AC power supply from an external power supply.
A 24V source power is supplied, and a plurality of power sources (DC5V, DC12V, DC24V, DC30V) having different voltages are generated from the source power by the power generation circuits 74, 75, 76, 77, and each power source corresponds. Each control board 22, 24, 2
9, 20, and 31, respectively (see FIG. 12). In addition, 24 V AC is supplied to the emission control board 18 from a power supply board 34 via a power distribution board 27 as it is, and a power supply circuit provided on the control board 18 generates a power supply of a required voltage.

That is, since a plurality of power supplies having different voltages used by the control boards 22, 24, 29, 20, 31 are collectively generated by the power supply board 34, a power supply generation circuit is provided for each control board. It is not necessary to provide each control board 22, 24,
29, 20, 31 can be downsized and the cost can be reduced. In the embodiment, the firing control board 18 is used.
Has its own power generation circuit, at least the main control board 22 and the payout control board 24 directly connected to the main control board 22, the symbol display control board 29, the voice control board 20, the lamp control board 31, and the like. Since a power supply generation circuit is not provided on a board that is replaced when the game board J is replaced, this greatly contributes to cost reduction. Further, the power supply voltage (5 V DC) for driving the IC circuit provided on each of the control boards 22, 24, 29, 20, 31 is also the power supply board 34.
The control boards 22, 24, 2
An error does not occur in the power supply voltage for driving the IC circuit in 9, 20, 31 and it is possible to preferably prevent the transmission and reception of signals between the control boards and prevent the circuit itself from being damaged.
As described above, the firing control board 18 is connected to the payout control board 24 (the firing control board 18 receives a firing stop signal from the payout control board 24 when the ball rental unit K is not connected to the interface board 28). (The firing is stopped only when the power is turned off) and is not connected to the main control board 22. Therefore, even if the firing control board 18 independently generates the power supply voltage for driving the IC circuit, it is inconvenient for the firing control. There is no danger of occurrence. Further, since the launch control board 18 is a component that is commonly used regardless of replacement of the game board J, the provision of the power generation circuit does not affect the cost.

In the pachinko machine P, the original power is not supplied to the power supply board 34 due to, for example, a power failure.
When the power supply board 34 is turned off, the main control board 22 and the payout control board 24
The backup power is supplied to the RAM, and information about the game when the power is turned off is stored and held in the RAM.
In other words, even if a power failure occurs during a special game state such as a jackpot or a probability fluctuation state, the game can be resumed from the continuation when the power is restored, or the number of unpaid balls or prize balls , And payout can be accurately performed 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 by closing the store or the like, backup power is supplied from the capacitor 78 to the RAMs of the main control board 22 and the payout control board 24. It is possible to carry over the memory changed to the probability fluctuation state at the time of closing the store to the next morning, or hold information on the number of unpaid balls and prize balls.

A capacitor 78 for supplying a backup power supply is provided on the power supply board 34, and the backup power supply is supplied on the same connector (wiring) as the normal power supply. There is no need to increase the number of separate substrates or wirings to be supplied, and it is possible to prevent an increase in the number of parts and the number of assembling steps, and to reduce costs. In addition, since there is only one capacitor 78 and backup power is supplied to the main control board 22 and the dispensing control board 24 at the same time, there is no possibility that an error occurs in the backup time in each of the control boards 22 and 24. That is, if an error occurs in the backup time (storage time) of the RAM, for example, the information stored in the main control board 22 is not stored in the payout control board 24, and there is a possibility that a problem may occur in the control during power recovery. However, occurrence of such inconvenience is prevented.

Next, in the pachinko machine P, when the monitoring power supply falls below a certain voltage, the power-off monitoring circuit 7
From 9, a power-off signal for switching from normal control to power-off control is output to the main control board 22 and the payout control board 24. 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 a voltage drop that hinders 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.

As described above, the power-off monitoring circuit 79 outputs a power-off signal when the monitoring power supply reaches the minimum power failure detection voltage at which the solenoid operates without causing a problem in a normal game. It is set as follows. That is, when the power-off signal is output, the solenoid driven by the highest voltage in the pachinko machine P operates normally, and all other electric devices also operate normally. And devices that have already become inoperable are not mixed. Therefore, by performing the backup processing at this time, the information of the main control board 22 and the payout control board 24 at the time of the backup processing does not conflict with each other.
Normal operation at power recovery is guaranteed. In addition, by the above-described power-off processing, all the CPUs are in a power-stop standby state before the power-supply is stopped, so that a failure of the CPU itself or a program due to the stop of the power-supply is prevented.

Further, after the power-off monitoring signal is output from the power-off monitoring circuit 79, each of the control boards 22, 24, 29,
In order to perform a reset process for operating the CPU normally at the time of power restoration at 20, 31 (a process of starting the program from address 0000 by performing a CPU security check and initial setting of the CPU when the reset signal falls). Is output from the reset signal circuit 80 to each of the control boards 22, 24, 29, 20, 31. That is, the normal operation of the CPU at the time of power recovery when the voltage returns to normal after the power failure is guaranteed. In addition, in the power supply board 34 of the embodiment, the power-off signal and the reset signal are output in any of the normal power OFF, the power failure, and the 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 the control boards to be controlled, the output of the power-off signal and the reset signal to each control board is It is performed simultaneously, and the timing of each processing for each control board can be adjusted. In other words, it is possible to prevent the occurrence of a problem due to a deviation in the timing of each processing for each control board. In addition, the power-off monitoring circuit 79 and the reset signal circuit 80 are connected to the power supply board 34.
In this case, there is no need to separately provide a circuit in a place other than each control board or power supply board, and the cost can be reduced. The power supply board 34
By detecting an abnormality of the voltage drop by the power-off monitoring circuit 79 provided in the CPU, it is possible to determine that there is a problem with the entire gaming machine.

In the pachinko machine P, when erasing the storage of the inspection at the time of factory shipment and the storage at the time of closing the store, the power switch 66 is turned on while the RAM clear switch 69 provided on the power supply board 34 is turned on. By turning on,
R for the main control board 22 and the payout control board 24
A clear switch signal for initializing AM is output from the RAM clear switch circuit 82, and information 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 turned on. Can be prevented. Also,
It is also possible to suppress malfunction due to generation of noise. Further, since the RAMs of the main control board 22 and the payout control board 24 are cleared by operating one RAM clear switch 69, the clearing processing of the RAMs of both control boards 22 and 24 is performed at the same time. Interference with control is prevented.

[0056]

Modification In the embodiment, a plurality of power supplies having different voltages used in a main control board and a payout control board, a symbol display control board, a voice control board, and a lamp control board which are directly connected to the main control board are connected to a power supply board. However, it is also possible to generate a plurality of power supplies having different voltages used by the emission control board together with the power supply board. In this case, the firing control board is connected to the power supply board without passing through the power distribution board, but since the firing control board is also arranged around the power supply board like other control boards, the two are connected. The length of the power supply wiring to be used is short, and the influence of noise is reduced. In addition, the power source generated by the power supply board should be at least the one used for the main control board, the symbol display control board, the voice control board, and the lamp control board which are exchanged with the exchange of the game board. Each of the boards and the launch control board may be provided with a power generation circuit.

The configuration in which the power supply device is detachably provided on the back cover member is not limited to the embodiment. For example, the first locking means on the back cover member and the mounting base and the first engagement member The stop means may have a configuration reverse to that of the embodiment. Further, the mounting base can be mounted by engaging means using holes and protrusions instead of fixing with screws. Further, the second engaging means and the second engaged means in the housing case body and the cover body which constitute the housing box body may have a configuration reverse to that of the embodiment, or may be elastically deformable provided on one member. It is possible to adopt a configuration in which the assembling is performed using an appropriate engagement hook. The means for attaching the housing box to the attachment base (the first engaging means and the first engaged means) is not limited to the structure in which the container is disengaged by sliding as in the embodiment, but uses holes and hooks. Other configurations, such as a method of attaching and detaching back and forth, can be adopted. The back cover member may be provided on a back mechanism set board. Further, since the power supply board is a non-replaceable part when replacing the game board, it is desirable to dispose the power supply board on a non-replaceable part when replacing the game board.

In the embodiment, RA for clearing RAM is used.
A power switch in which the M clear switch is disposed on the power supply board, but also functions as the RAM clear switch.
The (RAM clear means) may be of a button type, and the RAM clear switch circuit may be set so as to output a clear switch signal only when the power switch is pressed for a long time. Also, a switch that only turns on and off the power,
Switch to turn on / off power and clear RAM
A configuration in which two types of switches (RAM clear means) are provided on the power supply board may be employed. In this case, it is preferable to adopt a configuration in which a switch capable of turning on / off the power and clearing the RAM is covered with a cover member or the like to prevent erroneous operation of the switch. Note that in the configuration of the modified example, the RAM can be cleared by one operation in any case. The backup means may be configured by connecting a plurality of capacitors in series, or may be configured by connecting a single battery or a plurality of batteries in series.

In this embodiment, a reset signal is simultaneously output from a reset signal circuit on a power supply board to a main control board, a payout control board, a symbol display control board, a voice control board, and a lamp control board. In the initial state (CPU
Security check and initial setting of CPU.
The program is started from the 0000 number) .However, the time for the security check and the initial setting varies due to individual differences and performance of CPUs on each control board. The following configuration may be adopted in consideration of the case where the control board has not received the signal from the main control board because the operation has been started first. 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 of the main control board, the CPU of the other control board operates. A configuration may be adopted in which the CPU of the main control board is started from an initial state after an optimal state has been reached. With this configuration, the timing (ON, OFF) of transmitting the reset signal from the reset signal circuit on the power supply board to each control board is common to all control boards, but the reset timing on each control board is CP by input circuit
By shifting the timing of transmitting the reset signal to the U, the CPU of the other control board is changed to the CPU of the main control board.
It is also possible to start the initial state earlier.

[0060]

As described above, in the power supply board arrangement structure of the pachinko game machine according to the present invention, power is supplied from the power supply board to the periphery of the power supply board arranged substantially at the center on the back side of the game machine. Since the plurality of control boards are arranged, the length of the power supply wiring connecting the power supply board and each control board can be shortened, so that the wiring processing can be facilitated and the influence of noise can be reduced. Further, since the length of the power supply wiring between the boards is shortened, it is possible to prevent an incorrect board from being mounted on the way, and it is also possible to detect an incorrect board at an early stage.

Since a plurality of power supplies having different voltages used in each control board are generated at the same time by the power supply board, it is not necessary to provide a power supply generation circuit for each control board, and each control board can be downsized. In addition, the cost can be reduced. In addition, since the power supply voltage for driving the IC circuit provided on each control board is also generated at the same time by the power supply board, no error occurs in the power supply voltage for driving the IC circuit on each control board. It is possible to suitably prevent the transmission and reception of signals between the control boards from being hindered and the circuit itself from being damaged.

The power supply board can be handled in units of housing boxes and can be attached to and detached from a back cover member for protecting the cover on the back side of the game board, so that maintenance and replacement of the power supply board can be easily performed. Can be.
