POWER SOURCE CONTROL APPARATUS, RECEIVING DEVICE FOR REMOTE CONTROLLER AND OPTICAL COMMUNICATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a power source control apparatus, a receiving device for a remote controller and an optical communication apparatus whose power consumption in stand-by are decreased to nearly null and in which battery consumption in stand-by in battery driving is improved. SOLUTION: In the case of stand-by when a solid state relay 2 is in an off state, a switch circuit 23 connected between the remote control photodetective circuit 30 of equipment and a large capacity capacitor 22 is turned off to cut off power supply to the circuit 30. Then, when the LED of the circuit 30 being a photodetective element for receiving an optical signal for remote control from a transmission side detects the optical signal when the circuit 23 is in an off state, a control signal is outputted to turn on the circuit 23 to supply power to the circuit 30 from the capacitor 22.
