PROBLEM TO BE SOLVED: To provide a game machine where it is monitored by a control circuit board whether a motor for driving a hopper operates reasonably. SOLUTION: A driving signal or a stop signal is inputted from the control circuit board 50 to a motor driving circuit 86. When the driving signal is inputted to the motor driving circuit 86, voltage is supplied to the motor 85. The motor 85 is driven by receiving the voltage. When the stop signal is inputted to the motor driving circuit 86, the motor 85 is not driven. The voltage supplied to the motor 85 is detected by a voltage monitoring part 87 to output a feedback signal at an L level when the supplied voltage is higher than reference voltage and to output a feedback signal at an H level when the supplied voltage is not higher than the reference voltage. When a collation and judgment part 68 judges abnormality based on the driving signal and the feedback signal, an abnormality signal is inputted to an information part to give abnormality information through a speaker or a liquid crystal panel.
