The power recovery means that the voltage has reached a normal voltage when the power switch 67 is switched from OFF to ON, after a power failure, or at a momentary power failure. The power-off signal causes the slot machine 10 (the main control board 45 and the sub-control board 46) to return to the gaming state before the power-off state at the start of power supply (at power recovery) when the power is cut off. In this embodiment, the power-off monitoring circuit 69 for monitoring the power-off process generates a stop-processing signal for stopping the slot machine 10.

A reset signal is output. Further, the time until the reset signal is output after the power-off signal is output is the time of the main control board 45 and the sub-control board 46 that are started after the power-off signal is output. The power failure detection voltage and the reset detection voltage are set so as to be longer than the time required for the backup processing described later. Note that the reset signal circuits 45d and 46d that output the reset signal when the power is turned off are set to stop (OFF) the output of the reset signal after a predetermined time.

(About power-off processing)
Next, the power-off process executed by the main control CPU 45a and the sub-control CPU 46a when the power supply is cut off will be described.

  When the main control CPU 45a receives the power-off signal from the power-off monitoring circuit 69, the main control CPU 45a executes main control power-off processing based on the main control power-off processing program among the control programs stored in the main control ROM 45b. To do. Further, when the sub-control CPU 46a receives the power-off signal from the power-off monitoring circuit 69, the sub-control power-off process is performed based on the sub-control power-off process program among the control programs stored in the sub-control ROM 46b. Execute.

  The power-off monitoring circuit 69 outputs a power-off signal to the main control CPU 45a and the sub control CPU 45a at the timing when the voltage of the monitoring power supply drops to the power failure detection voltage. Thereby, before the various components of the slot machine 10 become inoperable, the main control CPU 45a and the sub control CPU 45a execute the power-off process, respectively. Note that after the power-off signal is output from the power-off monitoring circuit 69, the voltage of the monitoring power supply is further lowered and supplied to the reset signal circuits 45d and 46d disposed on the control boards 45 and 46. At the timing when the voltage drops to the reset detection voltage, reset signals are output from the reset signal circuits 45d and 46d to the corresponding control CPUs 45a and 46a, respectively.

(Main control power-off processing)
In the main control power-off process, as shown in FIG. 8A, the main control CPU 45a stores various control information stored in the main control RAM 45c as backup information in the main backup area of the main control RAM 45c (see FIG. 8A). Step A11). Thereafter, the main control CPU 45a calculates the checksum of the main control RAM 45c and stores it in the main backup area of the main control RAM 45c (step A12).

  Next, the main control CPU 45a prohibits access to the main control RAM 45c and waits for input of a reset signal from the reset signal circuit 45d. When the main control CPU 45a receives the reset signal, the main control CPU 45a regulates the operation of the main control CPU 45a. After the power supply is cut off, the backup power is supplied from the capacitor 72 of the backup unit 71 to the main control RAM 45c, and the backup information stored in the main backup area is held when the power-off signal is input.

(About sub-control power-off processing)
In the sub control power-off process, as shown in FIG. 8B, the sub control CPU 46a stores various control information stored and held in the sub control RAM 46c as backup information in the sub backup area of the sub control RAM 46c (see FIG. 8B). Step B11). Thereafter, the sub-control CPU 46a calculates the checksum of the sub-control RAM 46c and stores it in the sub-backup area of the sub-control RAM 46c (step B12).

  Next, the sub-control CPU 46a prohibits access to the sub-control RAM 46c and waits for input of a reset signal from the reset signal circuit 46d. When the sub control CPU 46a receives the reset signal, the sub control CPU 46a regulates the operation of the sub control CPU 46a. After the power supply is cut off, the backup power is supplied from the battery 85 mounted on the sub-control board 46 to the sub-control RAM 46c, and the backup information stored in the sub-backup area is triggered by the input of the power-off signal. Retained.

(About return processing)
When the power supply to the slot machine 10 is started, the reset signal circuits 45d and 46d continuously output reset signals to the corresponding control CPUs 45a and 46a until the supply voltage reaches the reset detection voltage. To do. When the supply voltage to the reset signal circuits 45d and 46d becomes equal to or higher than the reset detection voltage, the reset signal circuits 45d and 46d stop outputting the reset signal, and each control is triggered by the output stop of the reset signal. The return processing program is started in the CPUs 45a and 46a.

(Return processing for main control)
The main control CPU 45a executes the main control return processing based on the main control return processing program stored in the main control ROM 45b when the reset signal input is stopped. In the main control return process, as shown in FIG. 9A, the main control CPU 45a performs various control information stored and held in the main control RAM 45c in the same calculation process as the main control power-off process in step C11. Calculate the checksum based on Then, the main control CPU 45a determines whether or not the checksum calculated in step C11 matches the checksum stored and held in the main backup area of the main control RAM 45c (step C12). If the determination result of step C12 is negative, it is determined that there is an abnormality in the various control information (backup information) being backed up, and the main control CPU 45a proceeds to the process of step C13.

  Note that the negative result of the determination in step C12 may be that the main control power-off process was not performed normally when the power supply was cut off, or that the storage contents were abnormal due to noise or the like after the main control power-off process. May occur. In such a case, the checksum calculated in step C11 indicates an abnormality (abnormal value). In addition, there is a case where the power supply is not interrupted, that is, the main control CPU 45a is restarted. In this case, since the main control power-off process is not executed, the checksum itself is stored. Not retained.

  If the determination result in step C12 is negative, the main control CPU 45a determines that the RAM is abnormal, and performs error processing in step C13. In this error process, the control for disabling the progress of the game is performed so that the insertion of medals is not accepted and the operation signals of the insertion buttons 30 and 31 and the start lever 32 are not accepted, and a RAM abnormality error is notified. This error processing loops until the initialization operation for enabling the setting change by the setting changing means is performed (until step C14 is affirmed), and the loop is released by an affirmative determination in step C14. Then, the process proceeds to step C15. In step C15, the main control CPU 45a erases (RAM clears) various control information stored and held in the main control RAM 45c. Thereafter, the main control CPU 45c performs initial information setting for setting the slot machine 10 to a preset default state, and activates the slot machine 10 (step C16). The main control CPU 45a outputs an initial information setting command corresponding to the initial information set in step C16 to the sub-control CPU 46a (step C17), ends the main control return processing, and sets the initial state (default state). .

  On the other hand, if step C12 is positive, that is, if the backup information is correct, the main control CPU 45a activates the slot machine 10 based on the stored backup information (step C18). The main control CPU 45a outputs a return control command for designating control information stored and managed in the main control RAM 45c to the sub control CPU 46a (step C19). Then, the main control CPU 45a finishes the main control return processing and returns to the gaming state before the power supply is shut off.

(Return processing for sub control)
The sub-control CPU 46a executes the sub-control return process based on the sub-control return process program stored in the sub-control ROM 46b when the reset signal input is stopped. In this sub-control return process, as shown in FIG. 9B, the sub-control CPU 46a performs various control information stored and held in the sub-control RAM 46c in the same calculation process as the sub-control power-off process in step D11. Calculate the checksum based on Then, the sub control CPU 46a determines whether or not the check sum calculated in step D11 matches the check sum stored and held in the sub backup area of the sub control RAM 46c (step D12). If the determination result of step D12 is negative, it is determined that there is an abnormality in the various control information (backup information) being backed up, and the sub control CPU 46a proceeds to the process of step D13.

  Note that the reason for the negative determination result in step D12 is that the sub-control power-off process was not normally performed when the power supply was cut off, as in the case described with respect to step C12 of the main-control return process. In some cases, the storage contents may be abnormal due to noise or the like after the sub-control power-off process. In such a case, the checksum calculated in step D11 indicates an abnormality (abnormal value). In addition, there is a case where the power supply is not cut off, that is, when the sub control CPU 46a is restarted. In this case, since the sub control power cut-off process is not executed, the checksum itself is stored. Not retained.

  If the determination result in step D12 is negative, in step D13, the sub-control CPU 46a erases (clears RAM) various control information stored and held in the sub-control RAM 46c. Thereafter, the sub-control CPU 46a performs various initial settings, waits until the initial information control command output from the main control CPU 45a is input, and when the initial information control command is input, activates the slot machine 10 (step D14). The sub-control CPU 46a outputs control commands corresponding to the various initial settings set in step D14 to each effect device to be controlled (step D15), ends the sub-control return processing, and returns to the initial state (default state). ).

  On the other hand, if step D12 is affirmative, that is, if the backed up backup information is correct, the sub control CPU 46a waits until a return control command output from the main control CPU 45a is input. It is determined whether the control information that can be specified from the control command matches the control information stored and held in the sub-control RAM 46c (step D16). That is, in step D16, the sub control CPU 46a stores control information (backup information) stored in the sub backup area of the sub control RAM 46c and control information (backup information) stored in the main backup area of the main control RAM 45c. ) Is correct.

  If the determination result in step D16 is negative, that is, if the backup information stored and held in the sub control RAM 46c does not match the backup information stored and held in the main control RAM 45c, the sub control CPU 46a The process proceeds to D13 and the above-described processing is performed.

  If the determination result in step D16 is affirmative, that is, if the backed up backup information is correct, the sub control CPU 46a activates the slot machine 10 based on the stored backup information (step D17). Thereafter, the sub control CPU 46a outputs a sub return control command for designating control information stored and managed in the sub control RAM 46c to each effect device (step D18), ends the sub control return process, and supplies power. Return to the gaming state before the interruption.

(Operation of Example)
Next, the operation of the slot machine 10 according to the embodiment configured as described above will be described.

  When performing maintenance of the main control device 15 and the sub control device 16 in the slot machine 10, the power switch 67 provided on the power supply board 61 is switched from ON to OFF. When the power switch 67 is turned off, the supply of power (electric power) from the external power supply is stopped, and a power cut signal is output from the power cut monitoring circuit 69 to the main control board 45 and the sub control board 46. The main control board 45 and the sub control board 46 execute processing necessary for backup in response to the input of the power-off signal. That is, the backup power is supplied from the capacitor 72 of the backup unit 71 to the main control board 45, and the backup process on the main control board 45 is normally performed. Further, the backup process is normally performed also on the sub control board 46 by the backup power supplied from the battery 85 mounted on the sub control board 46. The backup information stored in the main backup area of the main control RAM 45c by the backup process is held by a backup power source supplied from the capacitor 72. The backup information stored in the sub-backup area of the sub-control RAM 46c by the backup process is held by the backup power source supplied from the battery 85.

  When the voltage supplied from the power supply board 61 to the reset signal circuits 45d and 46d is equal to or lower than the reset detection voltage, reset signals are respectively sent from the reset signal circuits 45d and 46d to the corresponding control CPUs 45a and 46a. Is output. Note that the reset detection voltage is set to a value lower than the power failure detection voltage as described above, and the reset signal is after the power-off signal is output from the power-off monitoring circuit 69 and the main control board. 45 and the sub-control board 46 are output from the reset signal circuits 45d and 46d after a time required for the backup process. And each control CPU45a, 46a performs the process which stops operation | movement with the input of a reset signal.

  In the slot machine 10 of the embodiment, the main control board 45 and the backup board 73 (through the backup wiring 84 different from the first power supply line 65 that electrically connects the power supply board 61 and the main control board 45. Since the main wiring side connector 65a of the first power supply line 65 is disconnected from the first main board side connector 50a or the main power supply side connector 63, the capacitor 72) is connected to the capacitor 72). The backup power is supplied to the main control RAM 45c via the backup wiring 84. That is, the backup information stored in the main control RAM 45c of the main control board 45 can be retained even if the electrical connection between the power supply board 61 and the main control board 45 is disconnected during maintenance or the like.

  The first main board side connector 50a to which the main wiring side connector 65a of the first power supply line 65 is connected and the second main board side connector 50b to which the wiring side connector 84a of the backup wiring 84 are connected are shown in FIG. As shown in FIG. 5, since the main control board 45 is mounted side by side, the circuit configuration for supplying power to the main control RAM 45c in the main control board 45 can be simplified.

  The first main board-side connector 50a is connected to the main control board 45 on the pivot-side end of the housing 11 in the reel / control unit 18 (housing member 44) to which the main control board 45 is attached. When the reel / control unit 18 is rotated with respect to the casing 11 between the storage position and the non-storage position, the power supply disposed in the storage space 20 of the casing 11 is mounted. The amount of displacement of the first power supply line 65 that connects the board 61 (the electrical box 62) and the main control board 45 can be reduced. That is, the margin of the first power supply line 65 necessary for allowing the reel / control unit 18 to rotate can be reduced, and the routing process of the first power supply line 65 is facilitated. The sub board-side connector 60 is connected to the sub-control board 46 at the end on the pivotal side with respect to the housing 11 in the reel / control unit 18 (housing member 44) to which the sub-control board 46 is attached. Since it is mounted, when the reel / control unit 18 is rotated with respect to the casing 11 between the storage position and the non-storage position, the power supply board disposed in the storage space 20 of the casing 11 It is possible to reduce the amount of displacement of the second power supply line 66 that connects 61 (the electrical box 62) and the sub-control board 46. In other words, the margin of the second power supply line 66 required to allow the reel / control unit 18 to rotate can be reduced, and the routing process of the second power supply line 66 is facilitated.

  Since the backup unit 71 is disposed in the storage member 44 to which the main control board 45 is attached and the backup board 73 and the main control board 45 are close to each other, the backup wiring for connecting both the boards 45 and 73 is provided. It becomes easy to confirm the connection state 84. In the embodiment, with the main control device 15 attached to the storage member 44, the backup unit 71 is stored close to the end of the main control board 45 where the second main board-side connector 50b is mounted. Therefore, the backup board 73 and the main control board 45 can be brought closer to each other. Further, since the main control board 45 and the backup board 73 are attached to the outer surface (rear and left side surfaces) of the storage member 44, the reel / control unit 18 is rotated to the non-storage position with respect to the casing 11. Thus, since both the boards 45 and 73 are exposed to the front side of the housing 11, the connection state of the backup wiring 84 to the both boards 45 and 73 can be more easily confirmed.

  Further, since the backup unit 71 can be attached to and detached from the storage member 44 independently of the main control board 45 and the power supply board 61, the replacement work when the replacement becomes necessary due to deterioration of the capacitor 72 or the like is easy. It is.
