Abstract
PURPOSE:To attain a correct remote control by prohibiting that a remote control signal is transmitted by itself when other remote control unit transmits a signal judging from the output of a pair of receiving circuits. CONSTITUTION:Transmission circuits 12 and 22 respectively control light emitting diodes 14 and 24 and the light emitting diodes 14 and 24 emit an infrared- ray signal in which a carrier frequency is f0 as a remote control signal. At such a time, control circuits 11 and 21 emit the infrared-ray signal after it is confirmed that receiving circuits 13 and 23 do not receive the signal. The infrared-ray signal goes to an acknowledgment signal to a transmitting/receiving unit 1 or a transmitting/receiving unit 2 to emit the infrared-ray signal and goes to an infrared-ray signal emission prohibiting signal to the transmitting/ receiving unit 1 or the transmitting/receiving unit 2 not to emit the infrared-ray signal. Even when plural remote control units are used, a correct remote control can be executed without the competition between remote control units.
