信信号発生回路。[Claims for Utility Model Registration] A parent device and a plurality of terminal devices each having a different unique address are connected by a pair of signal lines, and the parent device converts a transmission signal including an address signal into a voltage signal to the pair of terminal devices. A voltage is applied between the pair of signal lines during a reply signal period after sending the transmission signal to the signal line, and the terminal unit transmits the signal transmitted from the parent unit through the pair of signal lines. In the remote multiplex transmission device configured to receive a transmission signal and send a reply signal as a current signal to the pair of signal lines in response to a match between an address signal in the transmission signal and its own unique address, the terminal device a reply signal generating circuit installed in the switch, which includes a first switch circuit to which the voltage between the pair of signal lines is supplied, and a first switch circuit that is turned off in response to the reply signal
and a control circuit having a switch element that turns on the first switch circuit, and a control circuit that turns on in response to an address match signal input in response to the address signal and applies a voltage between the pair of signal lines to the control circuit. and a second switch circuit for supplying a return signal.
