PURPOSE:To relieve the load of a reception side by transmitting a remote control signal corresponding to a scan signal for a prescribed number of times being >2 when the scan signal of one period is inputted. CONSTITUTION:A control signal generating means 8 consists of a key encoder 6, an instruction decoder 7 and a 3-word counter 12 in a remote control transmitter provided with a timing signal transmission means 4, a control signal generating means 8, and a key matrix 5 and transmitting a remote control signal so as to allow the reception side to execute an instruction. The 3-word counter 12 outputs a key input permission signal 19 to the key encoder 6 when the 3rd word identical instruction code is outputted after scan signals S1, S2...SK are applied to the key input side. Thus, the remote control signal is transmitted surely to the reception side so as to prevent useless load from being applied to the reception side. |
