PROBLEM TO BE SOLVED: To provide a game machine which can save a proper control condition by properly monitoring the operation condition of electronic components at the time of the unexpected cut off of a power source. SOLUTION: A CPU makes drive signals output to a dispensing motor off condition in mask impossible interrupting processing when power source cut off interrupt is generated. Thereby, the drive of a ball dispense unit is stopped. Then the detected signals of a winning ball count switch and a ball dispensing count switch as dispensing detecting means are checked for a predetermined period. The processing is shift to the processing for storing the control condition in a backup RAM when a predetermined time passes. Accordingly, even the game balls dispensed about at the time when power source cut off signals is put on according to electric power failure are detected. COPYRIGHT: (C)2007,JPO&INPIT
