記載の遠隔制御用送信器。[Claims for Utility Model Registration] A utility model consisting of a plurality of operation key groups 2 and 3 corresponding to each of a plurality of control target devices, and a remote control circuit that generates a control signal for each control target device in response to key input, In a remote control transmitter, the remote control circuit includes an input changeover switch 60 for selectively enabling key operations of a given operation key group and disabling key operations of other operation key groups, The remote control circuit is equipped with a malfunction prevention circuit that prevents control signals created by key operations from being output to the device to be controlled for each group of operation keys, and the input selector switch 60 is used to control the device. A transmitter for remote control, characterized in that an operation key group other than the operation key group to be operated is connected to the malfunction prevention circuit, and the malfunction prevention circuit is operated by key operation of the operation key group. The malfunction prevention circuit includes a circuit 41 that outputs a prohibition signal to prevent a control signal from being output to a controlled device, and a circuit 41 that determines whether an operation signal generated by key operation is the prohibition signal. circuit 46
and a control circuit 47 that prevents the generation of a control signal when the operation signal is a prohibition signal. The prohibition signal output circuit 41 and the discrimination circuit 4 through the key.
6. The remote control transmitter according to claim 1, which connects the remote control transmitter with the utility model registration claim 1.
