Title: Controller for game machine
Inventor: ICHIHARA TAKAAKI
IPC: A63F7/02
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To stop a game machine when an oscillator has halted a normal motion to prevent an abnormal playing condition. SOLUTION: A setting register (a constant setter) 152 tentatively records a preset figure set by a CPU 110 or the like in a monitor (monitoring and stopping part) 150 of a pachinko machine (game machine). An oscillator (third oscillator) 156 periodically outputs pulses. A counter (second counter) 158 receives pulses from the oscillator 156 to start counting and clears the count when it receives pulses from the oscillator 162. A comparator 154 (first stopper) outputs a stop signal when the counted number reaches a preset figure and then, brings the CPU 110 to a stop. In this way, the CPU 110 is brought to a stop when the oscillator 162 has become unusable due to a fault. Since the pachinko machine is brought to a stop in accordance with the stop of the CPU, it prevents the device from getting to an abnormal playing condition.
