PROBLEM TO BE SOLVED: To improve radiation efficiency within a casing by reducing wiring among boards, to reduce the rate of occurrence of malfunction caused by severance or defective connection of electric wires, and to reduce the false operation of a main control circuit or a subordinate control circuit caused by exogenous noises.SOLUTION: The game machine includes the main control circuit 55, the subordinate control circuit 56, a liquid crystal display device 5 and various boards 61-63 and 110. The game machine also includes a communication means for the communication by a communication interface between the main control circuit 55 and the subordinate control circuit 56, between the subordinate control circuit and the liquid crystal display device 5, and between the subordinate control circuit 56 and the various boards 61-63 and 110. Each of the main control circuit 55, the subordinate control circuit 56, the liquid crystal display device 5 and the various boards 61-63 and 110 has a transmission means and a receiving means. When the receiving means receives a prescribed amount of data from the transmission means, the receiving means generates an acknowledgement signal to confirm the completion of the reception. When the transmission means completes transmission of the prescribed amount of data, the transmission means generates a pseudo acknowledgement signal to confirm the completion of the reception in a pseudo manner. |
