Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a device for fixing components, such as a fixed tape guide of a video tape recorder (VTR), to a chassis.

(b) Conventional technology Conventionally, when fixing parts with mounting accuracy to a chassis, a plurality of fixing parts 1, 1, 1 are required as shown in Fig. 3, and the top surface of these fixing parts is In order to ensure that the support plate 2 that supports the components on the receiving surface is tightly attached, the support plate is fixed by screwing at each fixing part, for example, as disclosed in Japanese Patent Application Laid-open No. 175985/1985 (G11B 33/12). The need arose.

(c) Problems to be solved by the invention In the above-mentioned conventional technology, an increase in the number of parts such as screws and an increase in the number of man-hours for screwing work etc. cannot be avoided.

(d) Means for solving the problem The present invention provides a main fixing part having a top surface consisting of a main receiving surface and an inclined surface that has a predetermined angle with respect to the main receiving surface and is connected to the main receiving surface. and a sub-fixing part which is provided in the direction in which the inclined surface is arranged with respect to the boundary line between the main receiving surface and the inclined surface, and has a sub-receiving surface on the upper part, and a main fixing part and a sub-fixing part are planted. Consists of a base and a support plate on which the component is supported and fixed to the main fixing part so that the bottom surface touches the main receiving surface.When the support plate is fixed to the main fixation part, rotation around the boundary line is possible. It is characterized in that the bottom surface of the support plate is pressed against the sub-receiving surface by the action of the biasing force.

(e) Effects Since the present invention is constructed as described above, it is possible to reliably and accurately mount a support plate that supports parts that require mounting precision with a minimum number of parts and work man-hours.

(f) Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an overall perspective view of this embodiment, in which a main circular boss 4 and two subsidiary circular bosses 5, 5 are planted and fixed on a mechanical chassis 3.

The main circular boss (main fixing part) 4 has a screw hole 4a in the center.
is arranged, and the top surface has a horizontal main receiving surface 4b and an inclined surface 4c having an inclination angle of about 10 degrees with respect to this main receiving surface 4b.
is formed, and the ridgeline of this inclined surface, that is, the main receiving surface 4
The boundary line L between b and the inclined surface 4c corresponds to the diameter of the main circular boss 4.

The secondary circular bosses (secondary fixing parts) 5, 5 have small diameter dowels 5a, 5a at their upper ends, and are located on the side where the sloped part 4c is arranged with respect to the boundary line L, that is, the direction in which the sloped surface 4c is sloped. A straight line N located at P and connecting the centers of the sub-circular bosses 5, 5 is perpendicular to a line segment perpendicular to the boundary line L, that is, it is parallel to the boundary line L.

A mounting plate 8 on which a tape guide post 7 of a VTR is mounted and fixed is screwed to the support plate 6 with screws 9, 9, and at positions corresponding to the main circular boss 4 and the secondary circular bosses 5, 5. A through hole 6a and positioning recesses 6b, 6b are provided. Note that the recesses 6b, 6
The size of b is designed to be slightly larger than the size of the dowels 5a, 5a.

In order to fix the support plate 6 to the mechanical chassis 3, the support plate 6 is screwed onto the main circular boss 4 using screws 10 by aligning the through hole 6a and the screw hole 4a. When the support plate 6 is brought into contact with the main receiving surface 4b and further pressed by this screwing operation, a counterclockwise rotation urging force M is applied to the support plate 6 about the boundary line L as shown by the arrow in FIG. works.

On the other hand, on the side of the sub-circular bosses 5, 5, dowels 5a, 5a
When this biasing force M acts with the dowels 5a and 5b fitted in the recesses 6b and 6b, the support plate 6 is pressed against the sub-receiving surfaces 5b and 5b, which have a larger diameter than the dowels 5a and 5a, and the two are brought into close contact. . Therefore, the dowels 5a, 5
The fitting of the support plate 6 with the recesses 6b and 6b restricts the position of the support plate 6 in the front-rear, left-right directions, and the position of the support plate 6 in the vertical direction is restricted by the biasing force M, so that the tape guide post 7 is attached to the mechanical chassis 3. can be securely fixed.

(g) Effects of the invention As mentioned above, according to the invention, the extremely simple structure that limits the number of screws to one location allows parts to be mounted on the base with high precision, and the number of parts and man-hours can be significantly reduced. It is of high practical value as it allows for significant reductions.
