Description

[Detailed Description of the Invention] The present invention relates to a substrate device to which a sliding or rotating lever is attached.

Conventionally, a support body for supporting a sliding or rotating lever in a tape recorder has been constructed by integrally molding it on a substrate such as a chassis using a material such as synthetic resin.
Some support members have a removal stopper screwed onto the support to prevent the lever from coming off.

1 and 2 show cross-sectional views of this type of device before and after screw tightening.

The support body 2, which is integrally molded with the chassis 1 from a soft material such as synthetic resin, has a support shaft portion 3. The support shaft portion 3 is loosely fitted into the hole of the lever 4, and the washer is secured with a screw 5. 6
By tightening the lever 4 to the support shaft 3, the lever 4 is slidably or rotatably attached to the support shaft 3.

Here, when the screw 5 is further screwed into the chassis 1 and tightened from the state shown in FIG. do.

Therefore, since the support body 2 is made of synthetic resin or the like, it deforms as shown in FIG. 2, and the outer diameter of the support shaft portion increases.

As a result, the lever 4, which was slidably or rotatably attached to the support shaft 3, has a narrower gap 8 between the guide hole 7 and the outer periphery of the support shaft 3, and the contact resistance with the support shaft 3 increases. Therefore, in order to operate the lever 4, a push button (not shown) or the like must be operated with more force than necessary.

Therefore, the present invention aims to provide a board device for a tape recorder or the like that can solve such problems, and one embodiment will be described in detail below with reference to the drawings.

3 and 4 are vertical sectional views of an embodiment of the board device of the present invention before screw tightening and after screw tightening, and FIG. 5 is an exploded perspective view of the same, respectively. show.

In addition, in FIGS. 3 to 5, parts equivalent to those in FIGS. 1 to 2 are represented by the same reference numerals.

That is, in the support body 2 of the present invention, the central portion is formed into a higher annular bulge so that this central portion becomes the pressed portion 9 that is pressed against the washer 6 when the screw 5 is tightened.
A groove 10 is formed along the outer periphery of the pressed portion 9 to be depressed in an annular shape at a lower level than the support shaft portion 3 .

Note that 11 is a center hole through which the screw 5 passes.

Here, the guide hole 7 of the lever 4 is loosely fitted to the outer circumference of the support shaft part 3, and the washer 6 is placed on the upper surface of the pressed part 9, and the screw 5 is screwed into the chassis 1 from the outside. Then, make the state shown in Fig. 3.

When the screw 5 is further tightened from this state, the pressing force compresses the support body 2 via the washer 6 and the chassis 1.

In this case, while the pressing force acts intensively on the pressed part 9 through the washer 6 and deforms the pressed part 9, the pressed part 9 and the support shaft part 3 are separated by the groove 10. In addition, since the support shaft portion 3 is hardly affected by the deformation of the pressed portion 9, it remains undeformed.

Therefore, as shown in FIG. 4, even after the screw 5 has been tightened, the diameter of the support shaft 3 does not increase, and the contact resistance between the support shaft 3 and the lever 4 does not increase as in the conventional case. The lever 4 does not become difficult to operate due to an increase in the amount.

Here, the height of the pressed part 9 is such that when the screw 5 is completely tightened, the washer 6 does not come into contact with the upper surface of the support shaft part 3, or even if it does, the support shaft part 3 hardly deforms. Needless to say, it is preferable to select it so that there is no problem.

According to the board device in a tape recorder etc. of the present invention,
The support provided integrally with the substrate is such that the pressed part that receives the pressing force from the means for tightening screws, etc. is formed higher than the shaft part on which the lever is rotatably or slidably attached, and the pressed part is Since a groove is formed between the shaft and the shaft,
Since the pressed part is compressed and deformed by tightening, the shaft part does not deform, or even if it deforms, it can be kept to a small amount, and the operating force of push buttons, plungers, etc. for turning or sliding the lever is reduced. This not only eliminates the need for more than necessary, but also solves the problem of lever malfunction.
