PROBLEM TO BE SOLVED: To prevent a tampering action of a signal path between a command input port and a sub control circuit in a sub board of a game machine to improve security.SOLUTION: A sub board 32 of a game machine comprises: an interface circuit 80 which operates at a first source power voltage Vcc1; a sub control unit 71 which operates at a second source power voltage Vcc2 different from the first source power voltage Vcc1, receives prescribed data through the interface circuit 80, and controls an operation of a notification device 43 on the basis of the prescribed data; and a voltage monitoring unit 93 which monitors a change in the first source power voltage Vcc1 applied to the interface circuit 80, and outputs a signal to the sub control unit 71 when abnormality is found in the first source power voltage Vcc1. The sub control unit 71 performs, when a signal is inputted from a first voltage monitoring unit 94, a prescribed notification in a sub device which does not share a drive power source with the interface circuit 80.
