Title: Game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 2000-07-14
Abstract: PROBLEM TO BE SOLVED: To prevent the control from being disturbed even when an instant power failure or the like for a power source which is recovered in an extremely short period of time is generated in a game machine being constituted in such a manner that the control state at that time may be kept when an unexpected power source interruption or the like occurs. SOLUTION: When the power source is about to be interrupted, a CPU performs a specified state retention, and then, performs an output port clearing process. Thus, this game machine is placed under a stand-by state wherein a system resetting is waited. Then, while the value of a counter is subtracted one by one, whether the value of the counter becomes 0(zero) or not is checked. When the value of the counter has become 0(zero), the process jumps to the head of a program. When the program starts operating, a game state recovering process is performed. Thus, the game control returns to the state at the time when the power source interruption signal is generated, and the game control is continued from that state. When the power source is being shut off as is, the CPU motion stops while the counter is prevented from counting up.  When the power source is recovered, the counter counts up, and the game control can be continued.
