The mode is switched to the mode corresponding to. However, since the operation mode code signal transmitted from the composite AV device is an infrared signal, the infrared signal from the composite AV device may not reach the remote control device depending on where the remote control device is placed. In such a case, since the transmission mode cannot be switched in the remote control device, there arises a problem that a desired AV device cannot be operated.

In the prior art of Patent Document 2, the output mode is switched to the VCR device or the DVD device by the output mode switching signal of the composite electronic device by the infrared signal from the remote control device. The transmission mode of the remote control device is not switched by a signal from the device.

Yes. In addition, the composite recording / reproducing apparatus 10 uses the operation target notification signal output from the operation target notification signal output unit 142 as A.
An AM wave transmission unit 17 is provided as AM wave transmission means for transmitting on the M wave (AM modulation).

The remote control device 20 is a microcomputer 21 for controlling the entire remote control device, a key operation unit 22 provided with a plurality of operation keys, and a predetermined remote control signal assigned to the plurality of operation keys is converted into an infrared signal to perform infrared operation. A remote control transmission unit 23 as a remote control transmission unit for transmitting a signal and an AM wave reception unit 24 as an AM wave reception unit for receiving an AM wave from the AM wave transmission unit 17 of the composite recording / reproducing apparatus 10 are provided. .

In addition, the microcomputer 21 of the remote control device 20 extracts the operation target notification signal from the AM wave received by the AM wave receiving unit 24, and when the transmission operation mode corresponding to the operation target notification signal is different from the current transmission mode, By switching the current transmission mode to a transmission mode corresponding to the operation target notification signal, a transmission mode setting unit 211 is provided for setting the remote controller itself to the transmission mode corresponding to the operation target notification signal.

The reason for using AM waves is that the distance that can be transmitted is short and can be set freely.
This is because it is expected that there will be little influence on the electric products around, and the remote control device 20 can receive even if it is in a box or a bag. Further, since the AM wave is a radio wave instead of infrared light, there is no directivity, and if the remote control device 20 is within a distance where the AM wave can be received, the remote control device 20 receives the AM wave as will be described later. Thus, the transmission mode can be automatically adjusted to the mode (DVD mode or VCR mode) of the composite recording / reproducing apparatus 10. Also,

Transmission is performed in the VCR transmission mode (step S9).

On the other hand, when it is determined that the current operation mode of the composite recording / reproducing apparatus 10 is the DVD mode (step S1), the operation target notification signal output means 142 of the microcomputer 14 transmits the DVD operation target notification signal to the AM wave. It outputs to the part 17 (step S10). Thereby, the AM wave transmission unit 17 transmits the DVD operation target notification signal on the AM wave (AM modulation) (step S11).
