PURPOSE:To eliminate the need for an exclusive use remote control reproducing operation device, by recognizing a remote control reproducing operating instruction voice whether or not it is a voice registered in the same band as a telephone circuit line in advance. CONSTITUTION:A remote control signal is applied to a detector 329 the same as the case with a conventional voice signal via a telephone line in the path of a line transformer 320, an analog switch S13 and a filter 328. When said signal is detected at detector 329, a detecting signal is applied to a control circuit 312 to bring the ICM tape section 314 into a reproducing drive state and a reproduced output is transmitted to a channel via a switch S7, a buffer amplifier 325, a switch S12 and the transformer 320. When the reproduction is finished, a voice synthesis section with a clock function 315 transmits a voice output as ''Reproduction of message is finished'' to the channel in the same path.
