DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Industrial Application Field) The present invention relates to a slide switch used in electronic equipment such as a personal computer or a word processor.

(Prior Art) A conventional slide switch will be explained with reference to FIGS. 5 to 8.

FIG. 5 is a perspective view showing the external configuration of the word processor. In this word processor, a keyboard 11 is attached to a housing 12, and a display device 13 consisting of, for example, a liquid crystal display device is attached to the housing 12 so as to be openable and closable. Here, for example, a display device 13 is provided on the housing 12.
A slide switch 14 is provided for adjusting the brightness.

FIG. 6 is a perspective view showing the structure of the slide switch portion, FIG. 7 is a side sectional view thereof, and FIG. 8 is a bottom view thereof. A printed circuit board 15 is fixed to the housing 12 with screws 16 and the like. A sliding volume 17 is fixed on the printed circuit board 15 by soldering, and its volume shaft 18 projects into a rectangular hole made in the housing 12.

The slide switch 14 is slidably attached to a slide groove 19 provided in the housing 12. A hole 20 is provided approximately in the center of this slide groove 19, and three holes provided at the bottom of the slide switch 14 are provided. Fitting claw 21a
, 21b and 21c extend into the housing 12 through the hole 20. The fitting claws 21a and 21b extend from one end side of the slide switch 14, and sandwich the volume shaft 18 to transmit the movement of the slide switch 14 to the volume shaft 18, and also fit into the rib 22 and slide. This prevents the switch 14 from falling off from the slide groove 19. On the other hand, the fitting claw 21c extends from the other end of the slide switch 14, and is fitted into the rib 23 to prevent the slide switch 14 from falling off together with the fitting claws 21a and 21b.

In such a configuration, when the slide switch 14 is slid along the slide groove 19, the fitting claws 21a,
21b and its movement is transmitted to the volume axis 18. As a result, the brightness of the display device 13 shown in FIG. 5, for example, is adjusted in accordance with the movement of the slide switch 14. In this case, the fitting claw 21a.

21b and 21c, slide switch 14
can move smoothly without falling out of the slide groove 19.

(Problem to be Solved by the Invention) Conventionally, fitting claws 21a, 21b, and 21c were provided on both sides of the slide switch I4 to prevent the slide switch 14 from falling off, so the switch width 111 had to be made smaller. However, there were problems that affected the miniaturization of the device. Further, when the slide switch 14 is slid, the bottom surface thereof rubs against the slide groove 19 and causes damage.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a slide switch for an electronic device that can reduce the switch width and does not damage the slide groove.

[Structure of the Invention] (Means for Solving the Problems) A slide switch for an electronic device according to the present invention has a slide switch installed in a lower part of a slide member slidably attached to a slide groove of a housing through a hole provided in the slide groove. A support member is provided that engages with the volume shaft inside the casing to transmit movement of the slide member to the volume shaft and supports the slide member so that it does not come into contact with the slide groove.

In addition, this supporting member is provided with a fitting claw that fits into a rib provided inside the casing to prevent the slide member from falling off from the slide groove. A rattling prevention member is provided on the surface to prevent rattling of the support member in the hole.

(Function) According to the above configuration, by sliding the slide switch along the slide groove, the support member transmits the movement to the volume axis, and for example, the brightness of the display device is adjusted.

In this case, since the slide member is supported by the support member so as not to come into contact with the slide groove, the slide member will not be damaged on the slide groove. Moreover, the fitting claw and rattling prevention member provided on the support member allow the slide switch to move smoothly without falling out of the slide groove.

(Example) Hereinafter, a slide switch for an electronic device according to an example of the present invention will be described with reference to the drawings.

FIG. 1 is a side sectional view showing the structure of the slide switch portion in the same embodiment, FIG. 2 is a front sectional view thereof, and FIG. 3 is a bottom view thereof. In each figure, the same parts as in the prior art are given the same reference numerals. The printed circuit board 15 is fixed inside the housing 12 parallel to the slide groove 19 with screws IB at appropriate intervals. A sliding volume 17 is mounted on the printed circuit board 15, and by sliding the volume shaft 18, the brightness of the display device can be adjusted, for example.

Here, in the same embodiment, the slide switch 31 is
It is slidably attached to the slide groove 19,
It can slide in the direction of arrow A along the slide groove 19. A support member 32 is provided at the bottom of the slide switch 31 and extends into the housing 12 through the hole 20 of the slide groove 19. This support member 32
has a notch 32a, which engages with the volume shaft 18, transmits movement of the slide switch 31 to the volume shaft 18, and supports the slide switch 31 here.

That is, the length of the support member 32 is the same as that of the printed circuit board 1.
5 to the slide groove 19 by X. As a result, the slide switch 31 is supported by the support member 32 in a state where it floats above the slide groove 19 by an amount X. In this case, the support member 32
The contact portion with the printed circuit board 15 is rounded, so that the support member 32 smoothly attaches to the printed circuit board 15.
It is possible to move on top.

Further, a pair of fitting claws 33a are provided at the tip of the support member 32.
, 33b is formed. This fitting claw 33a33b
is fitted into a rib 34 provided in the housing 12 to prevent the slide switch 31 from falling out of the slide groove 19. Furthermore, in the support member 32, a fitting claw 33a,
A rattling prevention rib 35 extending in the vertical direction is provided approximately at the center of the surface opposite to the surface on which the rib 33b is formed. The anti-shake rib 35 fits into a rib 3B provided inside the housing 12, and prevents the support member 32 in the hole 20 from wobbling. This allows the slide switch 31 to slide smoothly.

Note that the rib 36 is set longer than the rib 34 to prevent reverse insertion of the slide switch 31.

In such a configuration, when the slide switch 31 is slid along the slide groove 19, the support member 32 transmits the movement to the volume shaft 18. As a result, the brightness of the display device 13 shown in FIG. 5, for example, is adjusted in accordance with the movement of the slide switch 31. In this case, the tip of the support member 32 is attached to the printed circuit board 15.
Since the slide switch 31 is raised by an amount X above the slide groove 19, the slide groove 19 is not scratched.

Further, a fitting claw 33a formed at the tip of the support member 32
, 33b s and the anti-rattle rib 35 provided on the back surface of the support member 32, the slide switch 1
4 can be smoothly moved without falling off from the slide groove 19.

In this way, since the fitting claws 33a and 33b for preventing falling off are provided only on one side of the slide switch 31, the width g2 of the slide switch 31 can be made smaller than before. As a result, it is possible to realize a slide switch 31 with an innovative design in which the switch width is narrower, and the device can be made smaller.

Furthermore, if the support member 32 is bent as shown in FIG.
Since the fitting claws 33a and 33b can be easily removed from the volume shaft 18, the work of removing the slide switch 31 becomes extremely easy.

[Effects of the Invention] As described above, according to the present invention, since the falling-off prevention member is provided only on one side of the slide switch, the switch width can be reduced and the device can be made smaller. In addition, since the bottom of the slide switch can be slid without touching the slide groove, the slide groove can be prevented from being scratched.
Improved appearance quality.
