PROBLEM TO BE SOLVED: To improve convenience for the operation of game machines at game parlors without causing troubles in control even in case the instantaneous disruption or the like of the power source occurs. SOLUTION: When the instantaneous disruption or the like of the power source occurs to lower the voltage level of VSL below a specified value, the processing for the stoppage of the power supply is started. As a result, a return signal generated in the loop state thereafter is inputted into a reset terminal, the CPU takes a system resetting. The CPU executes a main processing and if no clear switch signal is received, the control is returned to the state leading to the generation of a power source disruption signal by a restoration processing, with the position from which the control of games is continued. This can prevent troubles in control in case of the instantaneous disruption of the like of the power source. On the other hand, when the clear switch signal is received in the main processing, an initialization processing is executed thereby improving convenience to the operations of game machines at game parlors.
