Further, power supply substrate 320 includes diode 515 connected between nodes H and I, and storage capacitor 51 connected between node I and the ground potential.
7 (0.022F), the node I and the storage capacitor 5
17 and a cutoff switch 521 that can switch the node b1-b2 between an open state and a conductive state. The diode 515 is a diode for preventing a backflow in which a current flows only when a predetermined voltage is applied between the node H and the node I in a direction from the node H to the node I. Node I is the backup DC5 of the distribution unit 320a.
Connected to V terminal. As described above, the cutoff switch 521 is a switch for cutting off the supply of the backup power. 319 protrudes outside.

Further, the power supply unit board 320 is provided with a power supply switch 3 for switching off / on the main power supply by switching between the nodes a1 and a2 between a conductive state and an open state.
23. The power switch 323 is a switch operated by a person in charge of a game arcade or the like. I have. By operating the main power switch 323 to open the node a1-a2, the connector 5
00 and the node B are disconnected and the main power supply is turned off, so that power supplied from outside the gaming machine is not received. As described above, since the power switch is provided in the gaming machine, the power can be turned off for each gaming machine as needed in the gaming arcade where a large number of gaming machines are installed, and the operation becomes easy. .

The power supply board 320 constructed as described above
Is supplied with 24 V AC (24 V AC) to the connector 500. The supplied AC 24 V is subjected to noise removal by noise removal capacitors 501 and 507, and then high-frequency components are removed by low-pass filters 502, 503 and 504. As a result, AC24 from which noise has been removed
V is input to two AC 24 V terminals of the distribution unit 320a. 24 V AC supplied to the nodes C and D is full-wave rectified by full-wave rectifier circuits 505 and 506, and the full-wave rectified 21 V DC (21 V DC) is supplied to the ground potential terminal D_GND and the DC 21 V terminal of the distribution unit 320 a. Supplied during. The full-wave rectified DC 21 V is a pulsating current having a peak of 30 V and an average of about 28 V. As mentioned above,
Since the load to which DC 21 V is supplied is a lamp or the like, a pulsating flow is sufficient.

The node F has smoothing capacitors 512, 5
30V DC (DC 30)
V) flows. The smoothed DC 30 V is supplied to the distribution unit 32
0a DC30V terminal. The switching regulator 509 converts the input DC30V to DC12V.
Convert to The converted DC12V is supplied to the DC12V terminal of the distribution unit 320a. Smoothing capacitor 511
Is a capacitor for removing a pulsation caused by a fluctuation of a load to which a voltage of 12 V DC is supplied. Switching regulator 510 converts input DC30V to DC
Convert to 5V. The converted DC5V is supplied to the distribution unit 320a.
Is supplied to the DC5V terminal. Smoothing capacitor 516
Is a capacitor for removing a pulsation caused by a fluctuation in a load to which DC 5 V is supplied.

As described above, since the AC input from the AC power supply is converted into DC and the converted DC is converted into a plurality of voltages by the power supply board 320, the control board does not need to convert it into a required voltage. The configuration of the control board can be simplified, and the size of the control board can be reduced. Further, the maintenance of the gaming machine can be facilitated by generating the power supply required for the control board by the power supply board.

The storage capacitor 517 is preferably an electrolytic capacitor, and stores electricity when the potential of the node H is high, and discharges when the potential of the node H decreases. As a result, DC 5 V for backup is supplied by keeping the potential of the node I at +5 V for a predetermined period.

Even when the potential of the node H falls below the potential of the node I in an emergency such as a power failure, the power supply substrate 320 does not allow the current to flow from the node I to the node H. The stored electric power is effectively supplied to each control board via a distribution unit 320a described later. In particular, since the backup power supply is a capacitor, the backup power supply can be configured at low cost, and high durability against repeated charging / discharging can be expected.

When the disconnection switch 521 is operated to open the nodes b1 and b2 to make them non-conductive, power supply to the node I from the storage capacitor 517, which is a backup power supply, is cut off.

Therefore, when power is not supplied from node H to node I, for example, when power cutoff switch 521 is operated when power switch 323 is turned off, supply of backup 5 V DC is performed. Will be shut off. As a result, each of the control boards 141, 143, 2 backed up by the backup DC5V
The RAMs 91 and 351 are initialized.

On the other hand, when electric power is supplied from the node H to the node I, that is, 24 V AC power (not shown) is supplied from outside the pachinko gaming machine 1 and the power switch 323 is turned on. When the cutoff switch 521 is operated when the
5V continues to be supplied by power from node H to node I.

The power supply voltage of “AC 24 V” is branched into two. One branch wiring pattern is further branched into two and connected to the connector 312a for the game control board 351 and the connector 312b for the illumination control board 141, respectively.

Are detachably connected. Wiring for power distribution 31
The other end of 4e is connected to the launch control board 44 via the launch control power supply relay board 53 (see FIG. 15).

As described above, since the power supply board 320 is provided with the connector for detachably connecting the power distribution wiring for supplying power to the plurality of control boards, the power supply board 320 is provided for each control board. , Each control board can be easily removed from the power supply board 320.

The pulsation of DC5V for backup supplied from the V terminal is removed.

From the power supply board 320 to each control board 141,1
The voltage of 5 VDC supplied to the power supply 43, 291, 351 is used for driving the microcomputer 1000. On the other hand, DC5V for backup is supplied to the input terminal VBB of the microcomputer 1000 (input terminal of the backup power supply of the RAM 1002).

Referring to FIG. 8 again, backup DC 5 V input to input terminal VBB of microcomputer 1000 (input terminal of backup power supply of RAM 1002) is 5 V while the gaming machine is operating. It is supplied from the creation function unit 320b via the backflow prevention circuit 515. Thus, while the gaming machine is operating, the potential of the input terminal VBB is maintained at a constant potential. Then, when the power supply from the external power supply is cut off due to a power failure or an OFF operation of the power switch 323 (see FIG. 6), the power storage circuit 517 that has been stored up to that time starts to discharge and the input terminal VBB In order to start supplying DC 5V for backup, a power failure or power switch 32
3 OFF operation, the input terminal VB
The potential of B does not change, and its memory data is retained.

Therefore, even when the power supplied to the pachinko gaming machine 1 is cut off in an emergency such as a power failure, the microcomputer 1000 stores the RAM 1002 when the power is supplied to the pachinko gaming machine 1 again. Can be restarted based on the control data stored in the. On the other hand, when it is desired to forcibly initialize the RAM 1002, both the power switch 323 and the cutoff switch 521 may be turned off.

It is clear from the figure what the case is when the clerk accidentally touches the cutoff switch 521 during the operation of the gaming machine and the power supply route from the power storage circuit 517 to the distribution unit 320a is cut off. As described above, even in such a case, the 5V generation function unit 320b sends the backflow prevention circuit 5
Since the power supply route to the distribution unit 320a via the power supply 15 is not interrupted, the potential of the input terminal VBB of the microcomputer 1000 (input terminal of the backup power supply of the RAM 1002) does not fluctuate at that moment.
It is kept at a constant potential.

For this reason, even when the shut-off switch 521 is operated during the operation of the gaming machine, the potential of the backup power supply input terminal VBB fluctuates rapidly from the predetermined backup potential to 0 volts. Under the influence, the CPU 1001 of the microcomputer 1000
Operation does not become unstable.

In particular, in the present embodiment, the first power supply line (from the 5V generation function unit 320b to the node X and the backflow prevention circuit 51) connecting the 5V generation function unit 320b and the input terminal VBB of the microcomputer 1000
5, line from node Y to input terminal VBB)
And a second power supply line connected to the first power supply line (a line from the node Y to the power storage circuit 517 via the cutoff switch 521), and the power storage circuit 517 is connected to the second power supply line. With the storage circuit 51
7 and the first power supply line between the shut-off switch 521
This can be realized by a simple configuration of disposing the.

The power supply for backing up the RAM for storing the control data provided on each control board is the power storage capacitor 517 provided on the power supply board 320, so that each control board 141, 143, 291, 351 No need to provide a backup power supply for each of the
There is also an effect that the size of the control boards 141, 143, 291, and 351 can be reduced without complicating the circuit.

For example, among connectors 312a to 312d of distribution section 320a on power supply board 320,
By removing a desired connector from the distribution unit 320a, power supplied to each control board 141, 143, 291, 351 can be cut off for each control board. Accordingly, the RAM 10 provided in the microcomputer 1000 of each of the control boards 141, 143, 291, and 351
Since the backup DC 5 V supplied to the power supply 02 is also shut off, the control data stored in the RAM 1002 disappears. Thus, by disconnecting the connector, each of the control boards 141, 143, 291, and 351 can be initialized independently of the other boards.

FIG. 10 shows each control board 14 shown in FIG.
Of the configurations of 1,143,291,351, for example,
It is a figure showing a specific example of the composition of payout control board 291.

The buffer circuit 2910 is a game control board 3
This is an irreversible input interface that allows transmission of signals only in the direction from 51 to the payout control board 291, but does not transmit signals from the payout control board 291 to the game control board 351. Therefore, there is no room for a signal to be transmitted from the payout signal board 291 to the game control board 351. Even if a circuit in the payout control board 291 is tampered with, a signal output by the tampering is not transmitted to the game control board 351 side. For this reason,
One-way communication of signals between the game control board 351 and the payout control board 291 is ensured, and an illegal act of inputting an incorrect signal from the payout control board 291 to the game control board 351 to perform an illegal control is ensured. Can be prevented.

The same circuit as the buffer circuit 2910 is provided not only for the payout control board 291, but also for each control board of the illumination control board 141, the sound effect control board 143, the emission control board 44, and the display control board 99. It is provided in. Therefore, the game control board 351 and each control board 141,1
One-way communication of signals between the control boards 43, 44, and 99 is ensured, and an illegal act of inputting an unauthorized signal from each of the control boards 141, 143, 44, and 99 to the game control board 351 to perform an unauthorized control is performed. It can be reliably prevented.

The I / O port 2911 is connected to the payout control board 2

The card unit 31 is equipped with a microcomputer (not shown) for controlling the card unit. In addition, the card unit 31 is provided with a usable indicator 32, a connecting stand direction indicator 33, and a card insertion slot 34 (see FIG. 1). A ball lending switch signal and a return switch signal are given to the balance display board 23 via the payout control board 291 in accordance with the operation of the player.

A card balance display signal and a ball lending display signal indicating the balance of the prepaid card (magnetic card) are given from the card unit 31 to the balance display board 23 via the payout control board 291. Card unit 31
A unit ball lending operation signal (BRDY signal), a ball lending request signal (BRQ signal), a ball lending completion signal (EXS signal), and a pachinko machine operation signal (PRDY signal) are exchanged between the ball lending operation signal (BRDY signal) and the payout control board 291. . In addition, although not shown, the card unit 31 is provided on the payout control board 291 from the card unit 31.
, A card unit connection confirmation signal used for confirming the connection on the payout control board 291 side.

When the power of the pachinko gaming machine 1 is turned on,
The payout control microcomputer 2914 of the payout control board 291 outputs a PRDY signal to the card unit 31. When the prepaid card is accepted in the card unit 31 and the ball lending switch is operated to input a ball lending switch signal, the microcomputer for controlling the card unit outputs a BRDY signal to the payout control board 291. When a predetermined delay time has elapsed from this point, the microcomputer for controlling the card unit outputs a BRQ signal to the payout control board 291. The payout control microcomputer 2914 of the payout control board 291
By outputting a ball lending signal to the prize ball device, a predetermined number of lending balls are paid out to the player. If ball rental is in progress,
The EXS signal is turned on. As a result, the payout control board 291 informs the card unit 31 that balls are being lent. That is, the EXS signal is also used to notify the card unit 31 that a ball is being lent. Then, when the payout is completed, the payout control microcomputer 2914 gives E to the card unit 31.
The XS signal is turned off. As a result, the payout control board 291 notifies the card unit 31 that ball lending has been completed. In other words, the EXS signal is used for transmitting two types of information, ball lending and ball lending completion.

As described above, all signals from the card unit 31 are input to the payout control board 291. Therefore, regarding the payout control, no signal is input from the card unit 31 to the game control board 351, and there is no room for the game control board 351 to be illegally input from the card unit 31 side.

The payout control board 291 is provided with circuits for driving solenoids, motors and lamps, but these circuits are omitted in the figure.
