<p>PURPOSE:To make it possible to confirm the operation state of a tape recorder remotely by providing mode display lamps corresponding to operation switches for recording, etc., of a remote control transmitter. CONSTITUTION:When play command button P of transmission part 1 of remote control unit 2 is depressed to send out a play command signal, it is demodulated by reception part 10 of receiver 27 and then sent to normally-open play command switching circuit 13, thereby closing the circuit. Namely, a tape is run at a constant speed. With the tape recorder in a play state, a frequency corresponding to the play state is modulated by transmission part 19 into a transmitting carrier for transmission. The transmitted carrier is demodulated by reception part 4 of remote control unit 2 and then transmitted to normally-open play state command switching circuit 6, which closes, thereby lighting play mode display lamp 7. In this way, the operation state of the tape recorder can remotely be confirmed.</p> |
