PROBLEM TO BE SOLVED: To provide a game machine that is able to speedily rise control means that exerts main control or peripheral control for a game.SOLUTION: When a reset signal 22 from a power failure monitoring circuit 20 is cancelled, the input of a CLR terminal of a monostable multivibrator rises. Therefore, a one-shot low pulse is output from this Q bar terminal. Due to this one-shot low pulse, the output of NAND rises, and a high pulse is input to a WD terminal of a watch dog timer IC27. Accordingly, a reset pulse is prevented from being output from an RST terminal of the watch dog timer IC27 after the cancellation of the reset signal 22. Therefore, a reset processing for MPU28 can be finished in one time, making it possible to rise the MPU28 immediately. |
