[0034]
The power failure guarantee power supply unit 403 rectifies the AC power supply (AC24V) supplied from the outside of the gaming machine via the overcurrent protection circuit 401 and the power switch 402 by the rectifier circuit 405, smoothes it by the smoothing circuit 406, and has a direct current of about DC32V. The power is sent to the power failure detection circuit 407, the DC18V generation circuit 408, the DC12V generation circuit 410, and the DC5V generation circuit 411. Moreover, the power failure guarantee power supply part 403 guarantees a supply voltage until the CPU reset of each control device after a power failure is detected, as will be described later.
[0035]
When the input voltage decreases to a predetermined power failure detection voltage (for example, DC 21 to 24V), the power failure detection circuit 407 outputs a power failure detection signal to the game control device 100 and the discharge control device 150 via the output buffer 412, and A reset signal is output to the game control device 100, the discharge control device 150, and other control devices after a predetermined time delay from the output of the power failure detection signal via the CR delay circuit 413 and the output buffer 414.
[0036]
When the power failure detection signal is received, the game control device 100 and the discharge control device 150 perform predetermined power failure processing. When the reset signal is received, the game control device 100, the discharge control device 150, and other control devices perform the operation of the CPU. Stop.
[0037]
The DC 18 V generation circuit 408 generates DC 18 V and supplies it to the game control device 100 and the discharge control device 150. The DC12V generation circuit 410 generates DC12V and supplies it to the game control device 100, the discharge control device 150, the display control device 200, the decoration control device 250, and the sound control device 300.

Further, DC5V is supplied to a DC5VBB generation circuit (backup circuit) 415 to generate a DC5V backup power supply, and this backup power supply is supplied to the RAMs of the game control device 100 and the discharge control device 150 to provide data (game data, (Prize ball data) is backed up.
[0038]
The power failure non-guaranteed power supply unit 404 supplies the DC power of approximately DC 32V obtained by rectifying and smoothing the supplied AC power (AC 24V) by the rectifier circuit 416 and the smoothing circuit 417 to the decoration control device 250 and the launch control device 350. Also, the NDC 24V rectified by the rectifier circuit 418 is supplied to the decoration control device 250. The power failure non-guaranteed power supply unit 404 does not guarantee the supply voltage during a power failure.
[0039]
A drive voltage DC of 18 V is used for the large winning opening solenoid 12 of the special variable winning device 11, the ordinary electric accessory solenoid 15 of the normal variable winning device 13, and the flow switching solenoid 41 of the discharge flow switching unit. A discharging motor 40 having a driving voltage of DC 12V is used for the discharging device.
[0040]
In addition, 500 and 550 are a board external connection terminal board and a frame external connection terminal board for connecting to a host computer (not shown) (a management device for comprehensively managing a plurality of gaming machines in the store). is there.
[0041]
Therefore, when a power failure occurs, the power is rectified and smoothed by the rectifier circuit 405 and the smoothing circuit 406 of the power failure guarantee power supply unit 403 of the power supply device 400, and the power failure detection circuit 407, the DC18V generation circuit 408, and the DC12V are generated. The DC power of approximately DC 32 V sent to the circuit 410 and the DC 5 V generation circuit 411 drops in voltage, but when the voltage drops to a predetermined power failure detection voltage (for example, DC 21 to 24 V), a power failure detection signal is output from the power failure detection circuit 407. Based on the power failure detection signal (NMI: input to the non-maskable terminal), the game control device 100 and the discharge control device 150 perform predetermined power failure processing.
[0042]
Since the DC voltage after rectification and smoothing at the time of the power failure detection is higher than the generated voltage of the power failure guarantee power supply unit 403 (for example, DC 21 to 24 V), the DC 18V generation circuit 408, the DC 12V generation circuit 410, The voltage of the DC power generated by the DC5V generation circuit 411 does not decrease, and maintains a predetermined voltage. Therefore, at this time, the large winning opening solenoid 12 of the special variable winning device 11, the normal electric accessory solenoid 15 of the normal variable winning device 13, the flow switching solenoid 41 of the discharge flow switching unit, the payout motor of the discharging device. 40 and the like are operable, and can be controlled by the game control device 100 and the discharge control device 150.
[0043]
Then, the voltage drop of the DC power sent to the DC18V generation circuit 408, the DC12V generation circuit 410, and the DC5V generation circuit 411 decreases the voltage of the DC power generated by the DC18V generation circuit 408, but the power failure detection circuit 407. The game control device 100, the discharge control device 150, and other control devices stop operating based on the reset signal (XSRST: input to the reset terminal) output from.
[0044]
FIG. 5 shows the control contents when the power failure of the game control device 100 occurs. When the power failure detection signal is input from the power failure detection circuit 407 to the NMI terminal, it is activated.
[0045]
In step 1, the interrupt enable / disable state at the time of power failure is saved. This is stored as information for determination in order to determine whether to return in an interrupt enabled state or in an interrupt disabled state when a power failure is restored.
[0046]
In step 2, all registers are saved, and in step 3, the stack pointer is saved. As a result, the CPU can recover from the state when the power failure occurred.
[0047]
In step 4, all ports off are output. Specifically, the normal symbol display 31 is turned off, all solenoids OFF, all external information OFF, and all command transmission ports OFF are output.
[0048]
That is, the large prize opening solenoid 12 of the special variable prize winning device 11 and the ordinary electric accessory solenoid 15 of the normal variable prize winning device 13 are controlled to be off, and the large prize opening solenoid 12 and the ordinary electric accessory solenoid 15 are in a state during power failure (special Transition to the closed state of the variable winning device 11 and the contracted state of the normal variable winning device 13).
[0049]
In step 5, a power failure inspection area (RAM) is set and a determination value indicating that the processing when a power failure occurs normally is set. This is for determining whether or not to recover from a power failure when the power is turned on.
[0050]
In step 6, access to the RAM is prohibited.
[0051]
When the reset signal is received, the operation is stopped.
[0052]
On the other hand, in the case of the discharge control device 150, when prize balls are discharged when a power failure occurs, the on-control of the discharge motor 40 of the discharge device is continued and the payout motor 40 is moved to the reference position (state during power failure). Make a transition. Further, the flow path switching solenoid 41 of the discharge flow path switching unit is controlled to be turned off, and the flow path switching solenoid 41 is changed to a power failure state (such as a prize ball flow path position of the flow path switching unit).
[0053]
When a latching type solenoid that maintains the state after the switching operation is used as the solenoid, the off control or the on control is performed according to the power failure state.
[0054]
With this configuration, when a power failure occurs, the large winning opening solenoid 12 of the special variable winning device 11, the normal electric accessory solenoid 15 of the normal variable winning device 13, the payout motor 40 of the discharging device, and the switching of the discharge flow path. An indefinite state of the electric drive device such as the unit flow path switching solenoid 41 does not occur, and the DC power generated by the DC18V generation circuit 408 and the DC12V generation circuit 410 of the power supply device 400 during the voltage drop. Thus, the operation of each electric drive device can be guaranteed, and each electric drive device can be shifted to the power failure state under the control of the game control device 100 and the discharge control device 150.
[0055]
For example, when a power failure occurs during a special game of jackpot where the special variable winning device 11 is open, the special winning prize device 11 can be operated in a power failure state by controlling off of the big winning opening solenoid 12. It is possible to control to the closed state which does not accept. Further, when a power failure occurs during the discharge of a prize ball or the like, the payout motor 40 can be returned to the reference position by turning on the payout motor 40 of the discharge device.
[0056]
Therefore, it is possible to ensure control against power failure and high reliability of the gaming machine.
[0057]
In addition, as an electric drive device, the large winning opening solenoid 12 of the special variable winning device 11, the normal electric accessory solenoid 15 of the normal variable winning device 13, the payout motor 40 of the discharging device, the flow path of the discharging flow path switching unit. Although the example applied to the switching solenoid 41 and the like has been shown, the motor of the hitting ball launching device, the discharging device provided with the payout stopping solenoid, the solenoid, and the motor when the ball guiding device is provided in the game area The present invention can also be applied. It can also be applied to relays and the like.
[0058]
Moreover, although the example applied to the pachinko gaming machine was shown as a gaming machine, it is applicable also to other gaming machines, for example, gaming machines, such as a pachislot and an arrangement ball.
[0059]
