PROBLEM TO BE SOLVED: To provide a game machine capable of suppressing the occurrence of abnormal operation even in the case where an AC power source is unstable or where the noise level in the periphery of a control circuit is high.SOLUTION: The CPU of a performance control unit 22 for executing performance control operation is constituted to be reset by an output signal of a forced reset circuit WDT or a system reset signal SYS and is constituted to advance control operation while updating the management data periodically (ST63), and execute, while keeping the storage content of a RAM, the subsequent control operation in the case where the correctness of the management data can be determined after the reset of the CPU (ST47). A main control unit 21 for controlling the game operation centrally is constituted to send an electric shut-off command indicating a power failure to the performance control unit 22 when receiving a power source abnormality signal ABN1, and the performance control unit 22 having received the electric shut-off command is constituted to store the corresponding data in the storage unit, so that the control operation returns to the initial state even when the forced reset circuit functions later. |
