PURPOSE:To eliminate the mutual interference by providing a peculiar address data to each signal device and transmitter in pairs and sending a data added with its own station address after an address data less by one bit is received. CONSTITUTION:One's own address number is added by an address identification circuit 5B and the data is sent from a transmitter 3B, then the signal is received by a signal device 1 and by signal devices 4A-4n. The signal device 4C detects the address of the transmitter 3B to identify it that the order of transmission of one's own station comes next and the timing supplying an address to the data of one's own station from the transmitter 3C, and sending the result is provided after the transmission of the transmitter 3B is stopped. Thus, the mutual interference among the transmitters 3A-3n is eliminated to realize a kind of synchronizing circuit.
