PROBLEM TO BE SOLVED: To prevent players from suffering disadvantage.SOLUTION: A first power supply monitoring circuit monitors a first power supply voltage. When the first power supply voltage becomes equal to or less than a first threshold or a third threshold, the first power supply monitoring circuit outputs an on-state power interruption signal. A second power supply monitoring circuit monitors the first power supply voltage. When the first power supply voltage becomes equal to or less than a second threshold or the third threshold, the second power supply monitoring circuit outputs an on-state reset signal. The second power supply monitoring circuit has a capacitor functioned as a delay circuit. Further, operation means outputs an operation signal according to the operation. Even when the power supply is stopped, storage means stores variation data changing according to a progress of the game, for a prescribed period. Initialization means initializes the storage content of the storage means on the basis of an input of the operation signal. Release means releases a prescribed abnormal state on the basis of an input of the operation signal.SELECTED DRAWING: Figure 13 |
