PROBLEM TO BE SOLVED: To provide a game machine capable of detecting discontinuity and short circuit generated in a solenoid constituting an object to be controlled such as a motor-driven accessory even during playing. SOLUTION: Only in a short period which is set to be short to the degree of avoiding shifting of a plunger, a solenoid control command signal is periodically inverted to input the detecting result signal of the solenoid from a detecting circuit to an arithmetic control circuit. Then, in the case when the control command signal and the detecting result signal are not coincident with each other, the generation of the discontinuity or short circuit is reported to a Hall computer to light an information lamp. For example, though discontinuity cannot be detected from the detecting result signal by making a low level at the time of discontinuity, the level of the control command signal in a detecting period is determined by accident. Thus, at the time of repeating a period, detecting result in both of the states of a low level and a high level can be obtained to detect the discontinuity and short circuit.
