PROBLEM TO BE SOLVED: To exactly grasp the number of game balls which are not put-out yet by surely carrying out the detection of already put-out game balls even when power supply is stopped, to reduce a program capacity for processing in the case of the stoppage of power supply, and to improve convenience in the operation of a game machine. SOLUTION: In processing in the case of the stoppage of power supply, data in an input port 1 to which the detection signal of a prize ball counting switch is inputted. Next, '1' is set as a processing number, the address of a switch timer for the prize ball counting switch is set to a pointer, and a switch check processing subroutine is called. By the switch check processing subroutine, the value of the switch timer is increased by one in the case of detecting 'on' of the switch. When the value is 2, a prize ball account value (a backup RAM area) is increased by one. When 'on' of a clear switch is detected in processing in the case of starting power supply, a controlling state is returned to the initial state without regard to the other conditions.
