<p>PROBLEM TO BE SOLVED: To provide a pachinko game machine capable of synchronism between the highest main control board and the lowest liquid crystal control board even when affected by noises.SOLUTION: When a DSP-ACK signal from a liquid crystal control board is not input within a DSP-ACK signal waiting time period, a sub-integrated MPU of a sub-integrated board transmits an identical transmission base command again to the liquid crystal control board. Even when a main or highest control board cannot recognize a failure caused between the boards of the sub-integrated board and the liquid crystal control board, the highest main control board solves the failure quickly on the sides of the sub-integrated board and the liquid crystal control board, so that any gap is hardly caused between the progress of the game by the main control board and the progress of the drawing of the liquid display by the liquid crystal control board. Accordingly, even when affected by noises, the synchronism between the highest main control board and the lowest liquid crystal control board, can be kept.</p> |
