Title: Game machine
Inventor: UCHIGASHIMA TOSHIHIRO
IPC: A63F7/02
Filed: 2001-02-15
Abstract: PROBLEM TO BE SOLVED: To precisely dispense a winning ball in the case of a power failure. SOLUTION: When a power source voltage of DC12 V is lowered to a reference voltage LV1 (point P7), an interrupt terminal XINT becomes effective by a function of a voltage monitoring circuit 70, and a CPU63 stops driving of a ball stopping motor 29b. When the power source voltage reaches a reference voltage LV3 (point P8), an output voltage of a backup voltage monitoring circuit 64 is changed to a lower level, and NMI is applied to the CPU63. In forced interruption processing by the NMI, the CPU63 is switched to a mode recognizing detection of a game ball when a detection signal from a winning ball dispensing switch 29a is raised from a low level to a high level. In this way, it is recognized that the winning ball is dispensed when the detection signal of the winning ball dispensing switch 29a is raised from the low level to the high level (point P9).  There is no need to wait for a drop (point P11) of the detection signal, so that failure in detection of the number of the number balls can be prevented.
