PROBLEM TO BE SOLVED: To provide a slot machine which prevents illegal actions with a simple circuit constitution. SOLUTION: The game machine includes: a main control section 50 which perceives the number of payments according to an output signal SN of a detection sensor SE and outputs a payment signal until the number of payments reaches a requirement number of payments; and a payment motor MO which pays valued items by rotation according to the payment signal PAY. A detection resistor Ra in which the current flows corresponding to the output signal SN of the detection sensor SE, a load resistor Rb connected in series with the detection resistor Ra, and an abnormality detection circuit 80 outputting a binary signal in response to the voltage of the connection point of the detecting resistor Ra and load resistor Rb are mounted. The output of the abnormality detection circuit is constituted to be a normal level when it receives a voltage which is through the detecting resistor Ra and to be an abnormal level when it receives a voltage which is not through the detecting resistor Ra.
