BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a support device for a VTR drive mechanism according to the present invention will be described below with reference to FIGS. 1 to 9 for a support device for a VTR drive mechanism in a camera-integrated VTR with a liquid crystal monitor. The same parts as those in the conventional example described above are designated by the same reference numerals, and the description thereof will be omitted. Here, FIG. 1 is a perspective front view of a main part showing a camera-integrated VTR with a liquid crystal monitor using the VTR drive mechanism support device of the present embodiment, and FIG. 2 uses the VTR drive mechanism support device of the present embodiment. FIG. 3 is a perspective left side view of an essential part of a camera-integrated VTR with a liquid crystal monitor, and FIG. 3 is a perspective right side view of an essential part of a camera-integrated VTR with a liquid crystal monitor using the support device of the VTR drive mechanism of the present embodiment.

FIG. 5 is a front view of the VTR drive mechanism support device of this embodiment. 6 and 6 are left side views showing a supporting device of the VTR drive mechanism of the present embodiment, and FIG. 7 is a V of the present embodiment.
FIG. 8 is a right side view showing the TR drive mechanism support device, FIG. 8 is a bottom view showing the VTR drive mechanism support device of the present embodiment, and FIG. 9 is a side view showing a mechanical mounting portion of the VTR drive mechanism support device of the present embodiment. It is a figure.

As shown in FIGS. 1 to 9, the support device for the VTR drive mechanism according to the present embodiment is provided with seat screws 14, 1 via a through hole 6a of a resin-made cabinet 6 having elasticity.
The VTR drive mechanism is supported by the cabinet 6 by screwing 5, 16 into the screw holes 8 a provided in the mechanical chassis 8.

Here, between the seat surface of the seated screw 14 and the cabinet 6, between the cabinet 6 and the mechanical chassis 8,
Diameter of through hole 6a of cabinet 6 and screws 14 and 1 with seat
Since a gap is provided between each of the fitting portions 5 and 16 and the fitting portion diameter, the VTR drive mechanism is supported by the elastic cabinet 6 in a floating state that is movable within a certain range. Therefore, the external force and vibration applied to the VTR are absorbed by the gap and the elasticity of the cabinet 6, so that they are difficult to be transmitted to the VTR drive mechanism, the stability of tape running is ensured, and the recording / playback image quality and sound quality are improved. Can be made.

Further, since the mechanical chassis 8 is attached to the cabinet 6 with a play, even if the cabinet 6 is deformed by an external force, the mechanical chassis 8 is deformed within a certain limit. It is possible to eliminate the influence of the external force on the VTR drive mechanism.

Further, in the supporting device of the VTR drive mechanism of this embodiment, the through hole 6a in the cabinet 6 is used.
Since the meat stealing hole 6b is provided in the vicinity of, the remaining connecting portion functions in the same manner as a leaf spring, and the seated screw 14, 15, 16 mounting portion of the cabinet 6 has increased elasticity and further external force or the like. It is possible to reduce the influence on the VTR drive mechanism.

In the support device for the VTR drive mechanism of the above-described embodiment, the seat screws 14, 15, 16 are directly screwed into the screw holes 8a provided in the mechanical chassis 8 through the through holes 6a of the cabinet 6. However, like the other embodiment of the present invention shown in FIG. 10, the resin bush 17 is press-fitted into the through hole 6 a of the cabinet 6, and the seated screws 14, 15 are inserted through the bush 17. , 16 may be screwed together to allow the mechanical chassis 8 and the cabinet 6 to be loosely fitted.

In the case of the support device for the VTR drive mechanism of the other embodiment, since the bush 17 is made of a material softer than that of the cabinet 6, the influence on the VTR drive mechanism by an external force or the like is further reduced. It is possible.

[0018]

The support device for the VTR drive mechanism according to the present invention comprises:
With the configuration as described above, not only the effect of external force and vibration on the VTR drive mechanism can be reduced to improve the image quality and sound quality of recording / reproducing, but also the metal frame in the above-mentioned conventional example, Since the bush is unnecessary, the number of parts can be reduced, and the device can be downsized.

Further, a flexible portion having flexibility is provided in the vicinity of the locking hole in the cabinet, or the engaging portion of the mechanical chassis and the cabinet are inserted through a member made of a material different from that of the cabinet. By loosely fitting the engaging hole, it is possible to further improve the recording / reproducing performance.
