PROBLEM TO BE SOLVED: To realize a game machine in which a main board can rise up after rising up a dispense control board. SOLUTION: A power source voltage monitoring IC 84 to monitor the power source voltage supplied to each board is equipped on a power source board 80 and detects voltages of a 32V line 86, a 12V line 87, and a 5V line 88 respectively from a voltage detecting lines A1, A2, and A3. When a detected voltage comes to a prescribed voltage, the power source voltage monitoring IC 84 outputs a reset signal to each board and, when a prescribed time is elapsed, the each reset signal is released in the order of a sub-board, a dispense control board 20, and a main board 100. When the detected voltage is out of normal range, the power source voltage monitoring IC 84 sends the reset signal to the each board to which the detected voltage is supplied.
