PURPOSE:To make a composition of a device simple and to prevent an erroneous operation by transmitting the first signal to execute a preliminary operation and transmitting the second signal to execute a control operation of a load after the preliminary operation of the load is confirmed. CONSTITUTION:The first and second signals are generated by a signal generating part 3, converted, for example, to a light signal from a transmitting part 4 and transmitted to a controlled object 5 having sharp directivity. The first and second signals converted to the light signal transmitted from the transmitting part 4 are received by a receiving part 6 and converted to an original electric signal by a decoding part 7. When a control part 8 receives the first signal, a load 2 is temporarily made active, and when the second signal is received, a load 2 is continuously made active. |
