線式発信器。[Claims for Utility Model Registration] A two-wire transmitter that transmits a signal output from a transmitting circuit via a two-wire power supply line, comprising: a light-emitting element that emits light with a current flowing through the power supply line; and the light-emitting element. a light receiving element arranged to receive light from the light emitting element and supplying a different output signal to the transmitting circuit depending on whether or not the light is received; and controlling light incidence from the light emitting element to the light receiving element by positional movement. A two-wire transmitter, characterized in that it is equipped with a control board.
