PURPOSE:To control plural control apparatuses by one optical signal transmitter by driving each light emitting element in accordance with information indicating the light emitting interval of the light emitting element inputted by a communication means. CONSTITUTION:The information of the light emitting interval inputted through a communication control part 16 is temporarily stored in a memory 18. A CPU 17 to be a control means analyzes the information of the light emitting interval stored in the memory 18 and turns on/off the output of an output port 19 by a time interval based upon the information. The signal of the output port 19 us inputted to a modulation circuit 4 and modulated by the circuit 4 together with and the output of a transmitter 3 transmitting subcarrier frequency, and a signal from the circuit 4 is amplified by an amplifier 5 to be a driving means, intermittently energizing a light emitting diode 6. Thus, an optical signal 7 for controlling an apparatus 14 to be controlled is outputted. Consequently plural apparatuses having respectively different code systems can be controlled by one optical remote control device. |
