簡単になるという利点を本発明は有している.Therefore, the user can listen to signals such as music played by the tape recorder built into the transmitter (1) at a location away from the transmitter (1). When the playback direction switching operation switch (23) provided in the receiving device (L2) is pressed and closed in the above-described playback operation state, the control signal generation circuit (24) generates a control signal for switching the playback direction. The control signal output from the control signal generation circuit (24) is sent into the air from the antenna (13) at the oscillation frequency of the oscillation circuit (18) as described above. 12〉
The signal sent from the transmitter (1) is received by a receiving circuit built into the transmitting device (1), and a control signal for switching the reproduction direction is output from the detection circuit {6} and applied to the operation switching control circuit (11). It will be done. As a result, the switching operation of the tape recorder is performed by the action of the operation switching control circuit (11), and the tape recorder enters a state of playback operation in the opposite direction. In this way, when the playback direction switching operation switch (23) is pressed and closed, the playback direction can be switched. Further, when the stop operation switch (21) is pressed and closed while the tape recorder is in the operating state, a control signal for switching to the stop state is output from the control signal generating circuit (24).The control signal generating circuit The control signal output from (24) is applied to the operation switching control circuit (11) through the detection circuit (6) after being received by the receiving circuit built in the transmitting device (Kei) in the same way as the control signal described above. As a result, the operation switching control circuit (11) switches the tape recorder from the playback operation state to the stop state.
In this embodiment, a monaural transmitter/receiver is described, but it is of course possible to implement the present invention in a stereo transmitter/receiver. Further, although the switching operation to the playback operating state, the switching operation to the playback direction, and the switching operation to the stop state are performed by remote control, it is also possible to perform fast forwarding, rewinding, etc. by remote control. Although we have described the case where the antenna (13) is provided in the receiving device (12), it is also possible to implement this in a device that uses the cord that connects the plug inserted into the headphone jack (20) and the headphones as an antenna. (G) Effects of the Invention The present invention provides a transmitting device with a control signal output from a control signal generation circuit provided in a receiving device that receives a playback signal from a tape recorder incorporated in the transmitting device. Since the operation of the tape recorder is changed by receiving the signal through the receiving circuit that is installed in the tape recorder, the operation can be changed while the transmitter, which is the main body of the audio equipment, is stored in a bag, etc., which is extremely convenient. It is something.
In addition, the output signal of an oscillation circuit provided to convert the radio wave signal sent from the transmitting device to an intermediate frequency as a radio wave signal sent from the receiving device to the transmitting device side, that is, the unnecessary radiation signal is used. Therefore, the present invention has the advantage that the circuit configuration is simplified.
