摘要
A remote control receiving device mounted on an apparatus has a switch circuit and an LED. The switch circuit is connected between a power supplied circuit of the apparatus and a power source. The LED functioning as a light receiving element receives an optical signal from a transmitting device. When the apparatus turns into a standby state based on an optical signal from a transmitting device, the switch circuit is brought into OFF by a microcomputer in the remote control receiving device. This intercept supply of power to the remote control light receiving circuit as well as the apparatus. When the LED receives an optical signal from the transmitting device, the LED outputs a electric control signal under an unbias state to turn on the switch circuit. Thereby, power is supplied to the apparatus.
