PROBLEM TO BE SOLVED: To accurately grasp the number of prize-balls which have not been put out yet, to prevent a hindrance from being generated in controlling even when instantaneous cutout of an electric source occurs and to improve utility on employment of a game machine in a game parlor. SOLUTION: In a mask-impossible interruption processing, a CPU for controlling put-out checks a detection keeping period and a prize ball counting switch and when ON is performed, the content of a memory on the over-all number is reduced by one. When an electric source cutout signal is generated caused by the instantaneous cutout of the electric source, under a waiting condition thereafter, reset is applied by a return signal and a main processing is started. When a clear switch signal is not received, it is returned to a control condition where the electric source cutout signal is generated by a put-out condition restoring processing and a put-out control is continued from the condition. It is therefore possible to accurately grasp the number of the prize-balls which have not been put out and to prevent the hindrance from being generated by the instantaneous cutout of the electric source and the like. On the other hand, when the clear switch signal is received in the main processing, an initialization processing is carried out. It is therefore possible to improve utility on employment of the game machine in the game parlor.
