PROBLEM TO BE SOLVED: To provide a game machine that makes a main control means perform a smooth control even when a plurality of control information are outputted from the main control means to a subsidiary control means. SOLUTION: A main control board C is structured so as to send a control command of a first byte and then send a control command of a second byte whose most significant bit is reversed after outputting one strobe ON signal and performing a prescribed waiting process. On the other hand, the subsidiary board S is structured so as to read the output values of data signal lines 22 to 29 by performing a command reception process, the interrupt process, when having received the strobe ON signal from the main control board C, monitor the output value of a first data signal line 22, and read the output values of the data signal lines 22 to 29 when the output value of the first data signal line 22 of the control command of the first byte read is reversed.
