摘要：A voltage applying circuit (310) having a photocoupler (140) and a resistor (144)applies a voltage corresponding to the magnitude of the communication current flowingthrough the transmission path to the receiving terminal (195).The reception control unit152 discriminates the presence or absence of a communication current by comparing thevoltage applied to the receiving terminal (195) with a predetermined voltage threshold.Avoltage regulation circuit (320) comprising a resistor (145) and a transistor (146)

regulates the voltage applied to the receive terminal (195) by the voltage applying circuit(310).The switching control section (153) controls the voltage regulation circuit (320) inaccordance with the magnitude of the communication current at the time of on control,

thereby switching the current threshold value to determine whether or not thecommunication current is present.
