PROBLEM TO BE SOLVED: To provide a game machine capable of surely resuming control of a game terminated by a power interruption when the power is restored.SOLUTION: The output of reset signals 22 is held on standby during a time of 9 ms when a low pulse of one shot is output from a prior-stage monostable multivibrator MM1 after a power interruption signal 21 is output. Power interruption processing (game termination processing at the power interruption) is thereby carried out during the time of 9 ms at the occurrence of the power interruption. Consequently, the operation of a game is stopped after the completion of the game termination processing. When the power is restored, each of the reset signals 22 is output to each of control boards C, H, D, L, B from a power interruption monitoring circuit 20, so that the control of the game terminated by the power interruption can be resumed surely. Consequently, even in occurrence of instantaneous interruption that is extremely short in time, the operation of the pachinko machine can be continued.SELECTED DRAWING: Figure 3 |
