PURPOSE:To simplify the program operation by sampling remote control signals of plural remote controlled apparatus with a high frequency and converting them to binary signals to store them in time series and reproducing and transmitting them. CONSTITUTION:A remote control transmitter 10 consists of a photodetector 100, a microcomputer 102, a liquid crystal display device 104, a driver circuit 103 of this device 104, a RAM 105 where binary signals are stored, a key circuit 107, a light emitting diode 110 which converts control signals to near infrared rays, etc. Operation programs of plural remote controlled apparatus are generated for respective signal sources and are stored in the RAM 105. An operator only operates a desired key button to read out a desired signal source and this source is reproduced to the original remote control signal and is transmitted, thus operating plural apparatus in preliminarily set states. |
