PURPOSE:To expand reach range of remote signals by connecting multiple remote control receivers mutually and transferring remote signals and at the same time to realize linked operation of multiple electrical apparatuses. CONSTITUTION:When a remote control signal of a remote control transmitter of apparatus B is input to apparatus A, the remote control pulse are input to the control circuit 8 through a received light processing circuit 1, an input inhibit circuit 5, a OR circuit 6 and a R/C decoder 7, but no control output is issued because the code is not matched. From the circuit 6 on the input side, the remote control pulse is output to the apparatus B via the output inhibit circuit 13, OR circuit 10 and an output terminal 11, and the remote control pulse input through the input terminal 3' is detected by the input detecting circuit 4' to operate the input inhibit circuit 5' to cut off the output of the received light processing circuit 1' and also is supplied to the control circuit 8' via the OR circuit 6' and R/C decoder 7'. And when the control codes are matched each other, the control output is supplied to the circuits. |
