Abstract
The invention is directed to decreasing the power consumption of a remote control signal receiving circuit. A receiving circuit includes a timing signal generation circuit generating a timing signal, a power supply circuit intermittently operating a light receiving element receiving a remote control signal by supplying power to the light receiving element when the timing signal is at a first level and by halting supplying power to the light receiving element when the timing signal is at a second level, a sampling signal generation circuit generating a sampling signal during the operation of the light receiving element corresponding to the timing signal, a sampling circuit sampling an output signal from the light receiving element corresponding to the sampling signal, and a detection circuit detecting the output signal sent from the light receiving element and sampled by the sampling circuit.
