PROBLEM TO BE SOLVED: To provide a game machine capable of transmitting/receiving data normally and stably and simplifying a connection mode related to communication easily.SOLUTION: A game machine comprises: a main board communication LSI610 which receives a command from a main CPU 601 and transmits communication data including the command; and a sub-board communication LSI710 which receives the communication data from the main board communication LSI610 and transmits it to a sub CPU 701. The main board communication LSI610 has a fourth Manchester circuit 621 which modulates the communication data. The sub-board communication LSI710 has a fourth Manchester circuit 721 for demodulating the communication data which is modulated by the fourth Manchester circuit 621.SELECTED DRAWING: Figure 57 |
