The contact 16b, the display contact 16c, and the video signal contact 16d are configured to be switched in conjunction with each other so that an arbitrary mode (the playback state of the image recording and playback device, which is mode C in FIG. 4) can be selected. .

Next, the operation of the present device will be explained using an example in which the second channel selection means 19 of this embodiment is used exclusively for recording in the image recording/reproducing device 11. For example, the monitor switch 16 is connected to the power switch 3) is placed in the A mode shown in FIG. 4, and the video signal from the first channel selection means 17 is displayed on the CRT 7, and the first channel selection display means 8a is A channel display corresponding to the channel selection mode of the first channel selection means 17 is shown.

At the same time, the second channel selection display means 8b shows a channel display in a channel selection mode corresponding to the second channel selection means 19, and the second channel selection display is recorded in the image recording and reproducing device 11. It is displayed that the signal indicated by the channel is being supplied to the means 8b. Here, the screen displayed on the CRT 7 is changed to the screen displayed on the CRT 7 by the switching display means 10a (in this example, a lamp is used) on the side corresponding to the first channel selection display means 8a. It is shown that the video signal is from the station means 17.

Assuming that the video signal from the second channel selection means 19 is being recorded in the image recording and reproducing device 11 in this state, when the monitor switch 16 is switched to B mode to check the above recording state, The video signal from the second channel selection means 19 is displayed on the CRT 7, and the second channel selection display means 8b
The corresponding switching display means 10b indicates that the screen of the CRT 7 is the image of the channel displayed on the second channel selection display means 8b. At this time, the first channel selection display means 9a displays a channel corresponding to the channel selection mode of the first channel selection means 17.
