PROBLEM TO BE SOLVED: To reduce wiring between boards, to improve heat radiation efficiency inside a housing, to lower the generation rate of a fault due to disconnection or connection defect or the like of electric wires, and to reduce the malfunction of a main control circuit or a sub control circuit due to external noise.SOLUTION: The game machine includes: a master communication device 67 provided in the main control circuit 55; at least one slave board 65; a slave communication device 68 provided on the slave board 65; and a communication means for transmitting information by a communication interface between the master communication device 67 and the slave communication device 68. The slave communication device 68 generates an acknowledge signal for confirming reception end when the prescribed amount of data are received from the master communication device 67, and the master communication device 65 includes a pseudo acknowledge signal generation means for generating a pseudo acknowledge signal for confirming the reception end in a pseudo manner when the transmission of the prescribed amount of data is completed. |
