<P>PROBLEM TO BE SOLVED: To increase a search range and save power in an object retrieval and display system. <P>SOLUTION: A transmitter 1 generates an infrared signal of ID (identification)individual information corresponding to individual information of an object input from the input section 4, and outputs it to a receiver 2. The receiver 2 includes a power ON/OFF control means for controlling a power source, and an optical sensor Cds. The power ON/OFF control means turns, when external light is sensed by the optical sensor Cds, on the power source of a first sub circuit for receiving a receiving start command from the transmitter 1. When the receiving start command is received from the transmitter 1, the power ON/OFF control means turns on the power source of a second sub circuit for receiving the ID individual information from the transmitter 1. When the ID individual information is received, the power ON/OFF control means turns on the power source of a main circuit. <P>COPYRIGHT: (C)2011,JPO&INPIT |
