A volume means is added to the audio signal control switch 208 so that the output ratio of the karaoke sound and the vocal sound is changed according to the change of the stroke of pressing the switch 208, and the switch 208 is pressed at all. The output ratio of the vocal sound from the speaker is zero when the switch 208 is not set, and the output ratio of the karaoke sound and the vocal sound is 50:50 when the switch 208 is completely pressed.
By setting the output ratio so that the vocal sound can be sufficiently recognized, the singer may be allowed to freely change the output ratio while singing only by feeling the hands. And
The volume means of the audio signal control switch 208 not only controls the output ratio of the karaoke sound and the vocal sound but also controls all the control items according to the present invention such as the volume from the speaker, the degree of echo, and the microphone volume (sensitivity). It can be applied. Further, the voice signal control switch 208 may output the vocal sound from the speaker or be turned off by repeating the pressing operation, and may display the output state on the monitor 16.

As shown by the chain double-dashed line in FIG. 11 (1), a speaker 194 is built in the image display device main body 12 or a remote control device 46 is provided in the grip 26 or the like.
May be attached. The remote controller 4 is attached to the grip 26.
When 6 is attached, the grip 26 is also provided with a receiver. As described above, the remote control device 4 is attached to the image display device body 12.
6 is held, the user of the video display device main body 12
It is not necessary to directly hold the remote control device 46, and the remote control device 46 can be easily operated. Further, the remote control device 46 may be attached to the image display device main body 12 and the remote control device 46 that is detachably held by the sub-control unit 38 may be provided. By providing the plurality of remote control devices 46 in this manner, not only the user of the video display device main body 12 but also another person can select music. The microphone may be a tie pin type microphone.

FIG. 12 shows a third embodiment. FIG. 12 (1) shows a case where it is adapted to a large sightseeing bus, for example. In this case, the video / audio signal extraction device 36 is installed, for example, on the upper front side of the passenger compartment of the bus, and is provided with a reception unit 212 on the front surface for receiving infrared rays emitted from the remote control device 46. This remote control device 4
6 can be detachably held by the video / audio signal extraction device 212 or the video display device main body 12 which is the main video display means.
