Abstract

PURPOSE:To miniaturize a mechanism concerned at low cost by forming a cylinder protecting material integrally with a cylinder mount on a cylinder mount placing a cylinder. CONSTITUTION:The cylinder 2 is fitted to the cylinder mount 1, and the mount 1 is fixed on a chassis 3. The plural bar-shaped cylinder-protecting material members 1a are integrally formed with the mount 1 on the mount 1. By this method, even when the mount 1 and the chassis 3 are miniaturized to such an extent that spatial room B between the cylinder 2 and an ornamental member 5 should not be zero, in the case of moving a VTR mechanism due to a fall, etc., direct abutting of the cylinder 2 with the ornamental member 5 is prevented by the members 1a. In addition, cumulative assembly errors of the cylinder 2, the members 1a and the mount 1 can be neglected, while no increase in cost takes place due to the addition of the members 1a.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a magnetic recording and reproducing device (hereinafter referred to as a VTR) that records and reproduces video signals, etc. on a magnetic tape that is wound at a predetermined angle around the circumference by a rotary head installed therein. In particular, the present invention relates to miniaturization of VTR mechanisms, such as VTR-integrated VTRs.

[Conventional technology]

In home VTRs and VTR-integrated cameras, - For boat fishing, cylinder 2 is attached to cylinder mounting base 1 as shown in Figure 4.
A method is used in which this is fixed to the chassis 3. As shown in Figure 5, the VTR mechanism used in the VTR-integrated camera connects VTR mechanism 4 to cylinder 1.
It is generally used standing upright with the side facing down, and the 6th and 7th
As shown in the figure, if the VTR mechanism 1 is placed upright, it will fall.

In order to prevent the cylinder 1 and the exterior member 5 from coming into contact when the mechanism moves within the set due to vibration or the like, the chassis 3. It is necessary to determine the shape of the cylinder mounting base 1.

However, when trying to downsize a VTR-integrated camera, it is necessary to close the space A between the cylinder 1 and the exterior member 5 in FIG. We are in a situation that simply cannot be resolved.

In addition, related devices such as those described in Japanese Patent Application Laid-Open No. 1983
-5065 publication is mentioned.

[Problem to be solved by the invention]

In the above-mentioned conventional example, when the VTR mechanism is used in an upright position, the protection of the cylinder is caused by closing the rear part of the cylinder on the chassis and the cylinder mounting base, which becomes an obstacle to downsizing the VTR mechanism.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a means for reducing the size of a VTR mechanism at low cost.

[Effect]

In order to achieve the above object, a cylinder protection member is integrally molded with the cylinder mounting base on which the cylinder is placed.

〔Example〕

An embodiment of the present invention will be described using FIGS. 1 to 3.

Fig. 1 is a perspective view of the cylinder mounting base according to the present invention, Fig. 2 is a front perspective view of the main part of the VTR integrated camera, and Fig. 3 is the VT
A side perspective view of the main parts of the R-integrated camera is shown.

The cylinder 2 is tilted at a predetermined angle and attached to the cylinder mount 1, and the cylinder mount 1 is fixed to the chassis 3 with screws (not shown).

As shown in FIG. 1, a plurality of rod-shaped cylinder protection members 1a are formed integrally with the cylinder mount 1. As shown in FIG.

As a result, as shown in FIGS. 2 and 3, the cylinder mounting base 1. Even if the chassis 3 is downsized, the cylinder protection member 1a prevents the cylinder 2 from coming into direct contact with the exterior member 5 when the VTR mechanism moves inside the VTR-integrated camera due to a fall or the like.

In addition, since the cylinder protection member 1a is integrally formed with the cylinder mounting base 1, compared to the case where the cylinder protection member 1a is a separate member from the cylinder mounting base 1, the cylinder 1, the cylinder protection member 1a, the cylinder mounting base The cumulative assembly error of cylinder 1 and cylinder protection member 1 can be ignored.
It is easy to ensure and manage the relative positional accuracy of a, and there is no increase in cost due to the addition of the cylinder protection member 1a.

Incidentally, the same effect can be obtained even if the cylinder protection member 1a is configured in the shape of a minus rod or a wall instead of the shape of a plurality of rods as shown in FIG.

〔Effect of the invention〕

According to the present invention, there is an effect that the mechanism can be made smaller while realizing cylinder protection.

Furthermore, it is easy to ensure and manage the relative positional accuracy between the cylinder protection members, and there is an effect that there is no increase in cost due to the addition of cylinder protection members.
