DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply board for a pachinko game machine, and more particularly to a power supply board for a pachinko game machine that uses a pachinko ball as a game medium. The present invention relates to a power supply board of a pachinko game machine configured to collectively generate power and supply the power to each control board.

[0002]

2. Description of the Related Art The basic structure of a pachinko machine is as follows: a window frame, a glass door, upper and lower ball plates, a hit ball launching device, a ball feeder, various ball processing, Game components such as a back mechanism set board having a part etc. are installed respectively, and inside the front of the front frame, a symbol variable display device, an electric winning device, a prize device with a switch, a game display device, a lamp and the like. A game board provided with an electric game device is set to be detachable and replaceable. In the back mechanism set panel, a main control board for controlling the entire pachinko machine, and a payout control board, a symbol display control board, a voice control board, a lamp control board, and a firing control board for controlling each component of the pachinko machine. Various control boards, such as control boards, are respectively arranged at predetermined locations, and various control boards are electrically connected to the main control board.

As described above, in a pachinko machine in which a plurality of control boards including a main control board are separated and separately arranged, a predetermined voltage is externally applied to a power supply unit arranged on one upper side of a back mechanism set board. (AC24V) is supplied, and the main power is supplied to each control board via a power supply line for connecting the power supply unit to each control board.
In each control board, a power supply of a required voltage is generated from a main power supply supplied from a power supply unit by a power supply generation circuit mounted on the board.

[0004]

Each of the plurality of control boards has a power supply generating circuit, and a voltage (for example, DC12V, DC24V) required by the control board in the circuit is provided.
However, in the configuration for generating the power supply of (2), not only the cost of each control board is increased, but also a drawback that the miniaturization of each control board is hindered is pointed out.

Here, in the pachinko machine, if a power failure occurs during a game, information stored in the RAM of the main control board and the RAM of the payout control board disappears, which is disadvantageous for the player and , Causing trouble between the game store and the player. Even if the game is in a special game state, the game is terminated when the game store is closed, and it is strongly desired by players to carry over the state the next day. It is proposed to provide backup means for supplying a backup power supply to the RAM at the time of a power failure or the like in each of the main control board and the payout control board. However, in this case, since a plurality of backup means are required, the number of parts and the number of assembling steps are increased, which leads to an increase in cost. In addition, each RA
M is supplied with backup power from separate backup means, so that an error may occur in the supply time. That is, for example, while information is stored and held on the main control board side, the information disappears on the payout control board side, which may give a disadvantage to the player.

In the case where the above-mentioned backup means is provided, the backup means may be installed in a game store with the stored information of the inspection at the time of shipment from the factory, and in this case, there is a possibility that the business may be hindered. It should be noted that there is also a demand for not storing stored information at the time of closing the store on the next day if necessary in the model of the gaming machine or the management of the game store.

As another countermeasure against power failure, the voltage of the power supply supplied to the pachinko machine is monitored, and when the voltage drops by a certain value or more, the RAM of both control boards at that time is monitored.
It has been proposed to perform a backup process for storing and holding the above information. However, the CPU in each control board is individually stopped when the power supply to the CPU is stopped, which may cause a problem in each CPU itself, a program, and the like. A disadvantage that operation is not guaranteed is pointed out.

In the above-mentioned backup processing, the CP
U is in a power stop standby state. For example, when the power supply voltage drops by a certain value or more but the power supply to the CPU is not interrupted and the power supply voltage returns to a normal voltage again, CP
U is held in a power stop standby state, and there is a possibility that a situation in which the operation of the pachinko machine is not restarted even though power is supplied may occur.

[0009]

Each is supplied to the control board. That is, since a plurality of power supplies having different voltages are generated at once by the power supply board, it is not necessary to provide a power supply generation circuit on each control board, and the control board can be downsized and the manufacturing cost can be reduced.

When the monitoring power supply becomes lower than the preset power-off detection voltage, a power-off signal is output from the power-off monitoring means to the main control board and the dispensing control board, and stored in both control boards. A backup process for retaining information is performed. In the power-off state in which the supply of the main power to the power supply board is stopped, backup power is supplied from the backup means of the board to the storage means of the main control board and the storage means of the payout control board, and the storage information of both storage means is stored. Is not detrimental to the player. Moreover, the backup time during which the backup power is supplied to both storage units is the same, so that a disadvantage caused by erasing only the storage information of one storage unit is prevented.

Further, after the power-off signal is output, the reset signal means for each control board sends the CPU of each control board.
Is reset from the initial state. Therefore, the pachinko gaming machine can resume normal operation even when the monitoring power supply returns to the normal voltage after the power supply becomes equal to or lower than the power-off detection voltage. Further, the information stored in the storage means of the main control board and the storage means of the payout control board can be arbitrarily initialized and erased by the clear means.

DC12V is used as a power supply for the circuit, and DC5V is used as a power supply for the IC circuit. The IC circuit is a CPU,
ROM, RAM (storage means) and the like are referred to.

That is, the power supply board 34 is
Power supply generating circuit 74 for generating DC5V from
A second power supply generation circuit 75 that generates DC12V from 4V,
A third power supply generating circuit 76 for generating 24 VDC from 24 VAC, and a fourth power generating circuit 77 for generating 30 VDC from 24 VAC, and different power supplies generated by the circuits 74, 75, 76, 77 correspond to the corresponding control. Substrates 22, 3
1, 29, 20, and 24, respectively. In the embodiment, the emission control board 18 includes a power generation circuit for generating power of different voltages used in the control board 18, and is supplied from a power board 34 via a power distribution board 27. The power supply circuit is configured to generate power of each voltage described above from the power supply of 24 VAC. The ball rental unit K is supplied with power of 24 V AC required for communication from a power supply board 34 via a power supply distribution board 27 and an interface board 28.

As shown in FIG. 13, a capacitor 78 (for example, an electric double layer type) is provided on the power supply board 34 as a backup means for backing up the RAM provided on at least the main control board 22 and the dispensing control board 24. (Although it is preferably used, other types can also be adopted). Then, when power is not supplied from the outside 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 RAM as the storage means of the main control board 22 and the RAM as the storage means of the payout control board 24. In response to this, backup power is supplied from the capacitor 78 to back up both RAMs, and information stored in the RAMs is stored for a predetermined time.
(Backup time). It should be noted that the backup time can be appropriately changed by replacing the capacitor with a capacitor having a different capacity.

The power supply board 34 is provided with a power-off monitoring circuit (power-off monitoring means) 79 for monitoring power-off, and when a predetermined monitoring power supply falls below a preset power-off detection voltage. Main control board 22 and payout control board 24
From the normal control to the power-off control (both control boards 22,
24 (including a backup process for retaining the information stored in the H.24). 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 perform a process (power-off process) necessary for backup for holding information stored in the control boards 22 and 24 at that time. It is supposed to run. In the embodiment, as the monitoring power supply,
A power supply of DC 30V for driving a solenoid, which is a power supply of the highest voltage generated by the power supply board 34, and the voltage of the power supply is a minimum value at which the solenoid (component) operates without causing trouble in a normal game. Voltage of about DC20
It is set so that a power-off signal is output when the voltage becomes lower than V (power-off detection voltage).

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.

The power supply board 34 has a reset signal circuit
(Reset signal means) 80 is provided, and after a power-off signal is output from the power-off monitoring circuit 79 (in the case of a complete power failure and a momentary power failure that returns to normal after the voltage drops momentarily below the power failure detection voltage). ), And when the power switch 66 is switched from OFF to ON (when power is turned on), the main control board 22, the payout control board 24, the symbol display control board 2
9. Operate each CPU from the initial state for each control board such as the voice control board 20 and the lamp control board 31
It is set to output (ON) a reset signal for performing a security check of the CPU and initial setting of the CPU and starting the program from address 0000. The reset signal output after the power-off signal is output is a main control board which is started by the power-off signal after the power-off signal is output as shown in FIGS. It is set so that it is output (ON) after the time required for the backup process (power-off process) of the 22 and the dispensing control board 24 has elapsed, and turned off after a predetermined time. The reset signal output when the power switch 66 is switched from OFF to ON or when returning after a power failure is as shown in FIG.
As shown in the figure, the reset signal rises at the same time as the power supply rises, and is set to be turned off after a predetermined time from the time when a predetermined voltage (for example, a power failure detection voltage (20 V) or a preset reset voltage or the like) is reached. I have.
The control boards 22, 24, 29, 20, 31 are shown in FIG.
When the reset signal input via the reset input circuit 84 shown in (1) changes from ON to OFF (falling),
Reset processing for starting each CPU from the initial state is executed.

Each of 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, the pachinko machine P returns to the normal state without completely stopping (at the moment of an instantaneous stop as shown in FIG. 15B).
Is a state in which the main control board 22 and the payout control board 24 that have received the power-off signal have completed the backup process and are in a state where the operation of the CPU can be stopped by turning off the power (power-supply standby state). For this reason, there is a disadvantage that the CPUs of the main control board 22 and the payout control board 24 do not perform the process in the power stop standby state for the stop. When the main control board 22 is powered off, the main control board 2
In the voice control board 20 receiving the silent command from
Even when the voltage returns to normal, no new signal is received from the main control board 22, so that the silent state is continued, and the voltage has returned to normal in the lamp control board 31 which has received the power-off command. In this case as well, no new signal is received from the main control board 22, so that the inconvenience that the lamp of the pachinko machine P is turned off is continued. 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 is provided with a RAM 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 43, and is configured to be able to be turned on and off from outside with a fingertip. The RAM provided on the power supply board 34
In the clear switch circuit 82, the RAM clear switch 6
Only when the power switch 66 is turned on while the power switch 9 is turned on, the RA is applied to both control boards 22 and 24.
It is set so as to output a clear switch signal for initializing M (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 a clearing unit for the storage unit, and when the storage information of the inspection at the time of shipment from the factory and the storage information at the time of closing the store are erased, The clear means for the storage means is suitably used. In addition, R of an Example
The AM clear switch 69 is always kept in the OFF state by an elastic means or the like (not shown).
When the switch 9 is switched to the ON state by a fingertip operation and then released, it automatically returns to the original OFF state.

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 of 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 attached to 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, the power supply board 34 collectively generates a plurality of power supplies having different voltages used in the control boards 22, 24, 29, 20, 31. Therefore, 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
There is no error in the power supply voltage for driving the IC circuit at 9, 20, 31 and the main control board 22 and the other control boards 24,
It is possible to preferably prevent the transmission / reception of signals from / to the circuits 29, 20, and 31 from being hindered or the circuit itself from being damaged. In addition,
As described above, the launch control board 18 is connected to the payout control board 24 (when the launch 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). Only when the firing control board 18 independently generates the power supply voltage for driving the IC circuit, there is a problem in the firing control. There is no fear. In addition, since the launch control board 18 is a component commonly used regardless of replacement of the game board J,
The provision of the power generation circuit has no effect on 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 is turned off, the power supply board 34 supplies a backup power from the capacitor 78 to the RAM of the main control board 22 and the RAM of the payout control board 24, thereby providing information on the game when the power is cut off. Are stored in both RAMs. 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 RAM of the main control board 22 and the RAM of the payout control board 24. Thus, the storage in the probability fluctuation state at the time of closing the store can be carried over to the next morning, or information on the number of unpaid balls or prize balls can be held.

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 increase in the number of separate substrates or wirings to be supplied, the increase in the number of parts and the number of assembling steps can be prevented, and the cost can be reduced. Moreover, since there is only one capacitor 78, the RAM of the main control board 22 and the RA of the payout control board 24
There is no possibility that an error will occur in the backup time during which the backup power is supplied to M. That is, both RAMs
If an error occurs in the backup time (storage time), for example, the information stored in the main control board 22 is not stored in the payout control board 24, which may cause a problem in control at the time of power recovery. The occurrence of such inconvenience is prevented. Therefore, there is no disadvantage to the player.

Next, in the pachinko machine P, when the monitoring power supply becomes equal to or lower than the power-off detection voltage, the power-off monitoring circuit 79 sends power to the main control board 22 and the payout control board 24 from normal control. A power-off signal for switching to control is output (see FIG. 15). 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 falls below the minimum power-off detection voltage at which the solenoid operates without causing a problem in a normal game. It is set to output.
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 process at this time, the main control board 22 and the payout control board 24
There is no discrepancy in the information at the time of the backup processing, and the normal operation at the time of power recovery is guaranteed. In addition, by the above-described power-off processing, all CPs are turned off before the power supply is stopped.
Since U is in the power stop standby state, it is possible to prevent the CPU itself, the program, and the like from malfunctioning due to the stop of the power supply.

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, when the power returns to normal after the power failure
The normal operation of the CPU in (see FIG. 15A) is guaranteed. In the power supply board 34 of the embodiment, the O
Since the power-off signal and the reset signal are output in any of the FF, power failure, and instantaneous interruptions, the power supply of the normal voltage is started again even in the case of the instantaneous interruption shown in FIG. At this time (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 factory inspection information and the information at the time of closing 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 used. Said RA provided in
When the power switch 66 is turned on while the M 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 sent to the RAM clear switch circuit 82.
, And the information stored in each RAM is deleted. 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 ON state of the RAM clear switch 69 is maintained. Can be prevented from being initialized.
In addition, malfunction due to generation of noise can be suppressed. Further, by operating one RAM clear switch 69, the RAM of the main control board 22 and the R of the payout control board 24 are changed.
Since the AM is initialized at the same time, the RAM clear processing on both the control boards 22 and 24 is performed at the same time, and it is possible to prevent the control timing from being disturbed due to a shift in the timing.

Here, the pachinko machine P of the embodiment is provided with a winning detection SW in all winning openings,
When the winning signal from each winning opening SW is detected, the number of winning balls corresponding to the winning opening is stored in the RAM, and is managed as the total number of winning balls for the main control board, and the winning ball control command corresponding to the number of winning balls is stored. And sends it to the payout control board 24. The total number of prize balls for the main control board is obtained by adding the corresponding prize balls each time a prize is won to the winning opening, and receiving a prize ball counting sensor signal (input detected each time a prize ball provided in the ball payout device L is paid out). Signal) is subtracted from the total number of prize balls for the main control board.
On the other hand, when the payout control board 24 receives the prize ball control command from the main control board 22, the payout control board 24 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 the prize ball counting sensor in the ball payout device, and subtracts -1 from the total number of prize balls for the payout control substrate. The payout operation is performed until the value of the stored total number of payout balls for the payout control board becomes 0.

Therefore, if 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 are 10, respectively,
Due to the timing shift of the RAM clearing process, a state occurs in which only the total number of award balls for the main control board is erased and the total number of award balls for the payout control board is not erased. In this state, the ball payout apparatus L operates. (The payout control board 24 performs the payout operation until the total number of prize balls for the payout control board becomes zero), and the total number of prize balls for the main control board becomes negative. Therefore, the main control board 22 recognizes that the total number of prize balls of the main control board becomes negative, and recognizes that the ball is in an excessive payout state due to a failure of the ball payout device L, notifies an error, and stops payout. There is a problem that the game is stopped. However, in the embodiment, since the timing of the RAM clear processing does not shift, the above-described problem does not occur.

The capacitor 78 of the power supply board 34
If the connector of the power supply line 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 RAM, both RAMs are initialized without using the clearing means for the storage means. Although it is possible to do so, the operation of attaching and detaching the connector is complicated, and if the connector is frequently attached and detached, the connector may be damaged. In addition, two connectors must be attached and detached. However, if one connector is forgotten to be detached, the above-described problem is caused, which is not practical.

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. (Plural types of power supply generation circuits) have been described.However, a plurality of power supplies having different voltages including a power supply voltage for an IC circuit used in a launch control board for controlling the hit ball launching device (component) are also applicable. It is also possible to generate it together with a power supply board (add a power supply generation circuit that generates 21.1 V DC used as a power supply for solenoids from 24 V AC). 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. The power generated by the power supply board may be at least one used for the main control board, the symbol display control board, the voice control board, and the lamp control board that are replaced with replacement of the game board. Each of the firing control boards may be provided with a power generation circuit.
In other words, it is not necessary to provide a power generation circuit for every control board that is replaced together with the game board, so that the recyclability after replacement is improved, and there is no wasteful disposal of the generation circuit. Have the advantage.
Note that the number of power supply generation circuits provided on the power supply board can be changed according to 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 voltage that is required for each control board 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 first locking means of 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 configuration in which it 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, the case where the backup power is supplied from the capacitor to the RAM of the main control board and the RAM of the dispensing control board, respectively, has been described. A backup power supply may also be supplied from the capacitor to the RAM (storage means) of the control board. The backup means for supplying backup power to both RAMs is not limited to the capacitor of the embodiment, but may employ another type.

In the embodiment, the case where the power supply for driving the solenoid is used as the monitoring power supply has been described. However, it is also possible to use a power supply for components such as other electric devices as the monitoring power supply. Also, the power-off detection voltage is not limited to the value of the embodiment, and may be any value as long as the minimum value at which the component receiving the monitoring power can operate. In addition, one backup means means a plurality of RAMs (for example, a device in which a plurality of capacitors are connected in series other than a single capacitor, a device in which one battery or a plurality of batteries are configured in series, etc. Storage means) are commonly referred to as means for supplying backup power to the storage means.

In the embodiment, R for initializing the RAM is
The AM clear switch is provided on the power supply board,
Power switch that also functions as a clear switch
(Clearing means) may be 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 long-pressed. In this case, the power supply switch and the RAM clear switch circuit constitute the clearing means for the storage means. Further, a switch for only turning on / off the power and a switch for turning on / off the power and initializing the RAM (R
(Which constitutes clear means for storage means in combination with the AM clear switch circuit). In this case, it is preferable to adopt 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. Note that in the configuration of the modified example, in any case, the RAM can be initialized by one operation.

In the 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.

As described above, in the power supply board of the pachinko gaming machine according to the present invention, a plurality of power supplies having different voltages used by a plurality of control boards are collectively generated by one power supply board. It is not necessary to provide a power generation circuit for each control board, so that each control board can be reduced in size and cost.

When the monitoring power supply falls below the preset power-off detection voltage, a power-off signal is output from the power-off monitoring means to at least the main control board and the dispensing control board, and stored in both control boards. Since the backup process is performed to retain the stored information, the game can be resumed from the state at the time of power failure when the power is restored, and there is no disadvantage to the player. In the power-off state in which the supply of the main power to the power supply board is stopped, backup power is supplied from the backup means of the board to at least the storage means of the main control board and the storage means of the dispensing control board. Since it is configured to retain the stored information, there is no disadvantage to the player. In addition, there is only one backup means for supplying backup power to both storage means, so that the number of parts and the number of assembling steps do not increase significantly, and the increase in manufacturing cost can be minimized. Furthermore, since there is only one backup unit, the backup power is supplied to both storage units at the same backup time, and disadvantages caused by erasing only the storage information of one storage unit are also prevented. . Furthermore, since the backup means is provided on the power supply board, another board, wiring and the like do not increase, so that the number of parts and the number of assembling steps are prevented from increasing, and the cost can be reduced.

After the power-off signal is output, the reset signal means sends a signal to the CPU of the control board.
Is configured to output a reset signal to operate the power supply from the initial state, so that, for example, even when the monitoring power supply returns to a normal voltage after the power supply drops below the power-off detection voltage, normal operation is resumed by the reset processing. I can make it. In this case, since the reset signal means is provided on the power supply board, another board or a connector for wiring connection does not increase, so that the number of parts and the number of assembling steps can be prevented, and the cost can be reduced. it can. Further, the factory inspection information stored in the main control board storage means and the payout control board storage means and the information at the time of closing the store are operated by the storage means clear means provided on the power supply board. It can be easily erased just by doing. In addition, since the storage means of the main control board and the storage means of the payout control board are initialized at the same time, it is possible to prevent the control processing from being hindered due to a shift in the timing of the clear processing of both storage means.
