Abstract
A signal transfer circuit according to the present invention includes a differential signal generation unit that generates a differential signal according to a voltage difference between two input signals, a voltage difference detection unit that detects a voltage difference between the two input signals input to the differential signal generation unit, and a signal output unit that outputs a signal including a predetermined value if the voltage difference is not detected by the voltage difference detection unit, and outputs the differential signal generated by the differential signal generation unit if the voltage difference is detected by the voltage detection unit.
