<P>PROBLEM TO BE SOLVED: To provide a game machine restraining overvoltage above a specified voltage which may be instantaneously applied to a control unit, and reducing shortcomings, such as functional stop, of the control unit which is caused by the overvoltage. <P>SOLUTION: The Pachinko game machine 10 includes an outer frame 11 and an inner frame 12 openaly/closably provided at one side part of the front part of the outer frame 11. The game board has a back side provided with a control board mounted with a CPU having a built-in RAM holding game-relating information. When driving power supplied to the CPU is blocked, backup power is supplied to the CPU (RAM). Back-up wiring on the control board is provided with a noise-removing capacitor, an electrical discharge unit for discharging electrical charge accumulated in the noise-reducing capacitor, and a filter unit for passing a direct current component and restraining the passage of an alternate current component. <P>COPYRIGHT: (C)2012,JPO&INPIT |
