PROBLEM TO BE SOLVED: To provide a game machine capable of simplifying a program for lowering capacity by controlling the practicing timing of a sheltering means with the timing of interruption permission. SOLUTION: INT interruption processing for conducting processing in case of blackout is constituted in a state where the inhibition setting of interruption is possible. When timer interruption processing for controlling a game is practiced, an MPU21 comes into the state of interruption inhibition. Thus, though a blackout signal 51 is outputted in the middle of the practice of the control of the game and INT interruption occurs, its practice is made to wait until the timer interruption processing is finished and interruption is permitted at the S19 of main processing. Thus, it is possible to control the practicing timing of blackout time processing with the timing of interruption permission. Consequently, only with timing suitable for the practice of the blackout time processing, the blackout time processing is practiced. To the contrary, with timing inconvenient for the practice of the blackout time processing, the practice can be made to wait. Thus, a control program can be a program of simplification and a small capacity. COPYRIGHT: (C)2003,JPO
