PROBLEM TO BE SOLVED: To provide a multiplex communication equipment by which a cost for a communication system is reduced and the size of the system is miniaturized. SOLUTION: A logical circuit 13 in a state where a signal is not transmitted from each CPU 11, a logic circuit 13 always has a high-level signal inputted from each CPU 11 and outputs the high-level signal to a communication driver 12. When a low-level signal is inputted to the logic circuit 13, the communication driver 12 has a low-level signal inputted preferentially. Consequently, a binary logic signal transmitted from a CPU 1 computing the function of a module 1 is outputted to the communication driver 12 as it is. COPYRIGHT: (C)2003,JPO
