However, by transmitting an audio signal, the main body 21 is operated while confirming the audio in addition to the video at hand. Further, by transmitting the operation status of the main body 21 to the remote controller 22 as a control signal and displaying it on the liquid crystal display monitor 25 at hand, the operation status of the main body 21 can be confirmed from a distance. . Needless to say, an audio output terminal such as an earphone terminal or a headphone terminal may be provided instead of the speaker 39.

Furthermore, in the first, second, and third embodiments, the AV signal transmitters 14, 27, 32 and the AV signal receivers 17, 26, 38 are optical transmission devices, but the transmission method is optical. It is obvious that the effect obtained by using radio waves is not limited to the above, and the AV signal transmitting apparatus 1
4, 27, 32 and AV signal receiving device 17, 26, 3
Although 8 is the configuration of the FM modulation system, the transmission system is not limited to the FM modulation, and there are various transmission systems such as AM modulation and pulse width modulation. It does not deviate from the main idea and the effect obtained is the same. Further, it goes without saying that the monitor device for displaying an image is not limited to the liquid crystal display monitors 13, 25, 30 and there are various development examples such as a plasma type monitor and a cathode ray tube type monitor.

[0019]

As described above, according to the remote controller and the video recording / reproducing apparatus of the present invention, since the reproduced image of the video recording / reproducing apparatus or the image being recorded can be confirmed by the remote controller at hand, for example, the video recording / reproducing apparatus is a camera. In the case of an integrated video tape recorder, various new usages are possible, such as the usage in which the user himself / herself is the shooting object as well as the usage by remote control from a distance. In addition, since the video signal transmission from the video recording / playback device to the remote control is cordless transmission, it is eliminated from the limitation of the cord length at the time of remote operation when the cord is connected and the troublesomeness such as the cord getting in the way when used. The usability of the video recording / reproducing apparatus is improved, and the effect produced by the present invention is great.
