Further, in the case of the above-mentioned second conventional example, only the lens portion can be panned and tilted, and the image can trace the subject, but the voice input is fixed because the voice input is fixed. There is a problem that it is not facing the optimum input in the direction of the subject, and there is no explicit description of the configuration that allows the lens unit to rotate greatly just by panning and tilting. Further, as shown in FIG. 11 showing a side view of the use state of the lens-movable camera-integrated VTR, the subject A is surrounded by the camera-integrated VTR 7 placed on the VTR stand 6 from the original position B. 18 horizontally
When the camera moves to 0 degree and reaches a position C directly behind the camera-integrated VTR 7, the lens 10 movably mounted in the tilt direction by the pivot bearing 9 on the side surface of the VTR 8 cannot track the movement of the subject A in the horizontal direction. It is difficult to imagine that the lens 10 points the subject A. In addition, 11 is a microphone and 12 is a viewfinder.
The video camera of FIG. 11 is obtained by removing the overhanging portion for preventing excessive rotation in the embodiment of Japanese Patent Laid-Open No. 4-271672.

The present invention solves the above-mentioned problems of the prior art, does not require a means for vertically inverting the display screen, and allows tilting and panning at an angle of 360 degrees or more with the camera-integrated VTR fixed. The present invention relates to a camera-integrated VTR that can easily record sound in the direction of the lens of the camera.
