PROBLEM TO BE SOLVED: To provide a game machine capable of preventing excessive put-out of game media and capable of detecting the abnormal put-out of game media. SOLUTION: By varying the level of a hopper control signal to such a voltage level that a photo-coupler PC1 and a photo-coupler PC2 are turned on, a transistor TR1 is turned on to drive a hopper motor 82. By varying the level of the hopper control signal to such a voltage level that the photo-coupler PC1 and the photo-coupler PC2 are turned off, a transistor TR2 is turned to electrically connect one input terminal to the other input terminal of the hopper motor 82. Based on the state of the signals from a comparator CP1 and a comparator CP2, such abnormal put-out that the power supply is fed to a line L11 while the hopper control signal is on or that the power supply is not fed to the line L11 while the hopper control signal is off is determined and announced.
