PROBLEM TO BE SOLVED: To provide a game machine enabling checking of failures in photosensors without giving an irritated feeling to players.SOLUTION: If an instantaneous power interruption occurs during a player is playing a game and then the power is restored, as a main control board does not send a RAM clear notification command to a sub integrated board, the sub integrated board does not have to perform a test of photosensors 150n, 152n, 153n, and 154n. On the other hand, as managing persons in a game hall (such as the staff of the hall) send the RAM clear notification command to the sub integrated board by an operation of a RAM clear switch, the sub integrated board receiving the RAM clear notification command is set to perform a test of the photosensors 150n, 152n, 153n, and 154n. Accordingly, failures of the photosensors 150n, 152n, 153n, and 154n can be checked without giving an irritated feeling to the player.SELECTED DRAWING: Figure 8 |
