Description

[Detailed Description of the Invention] This invention relates to a pointer attachment device for a slide indicator used in a receiver tuner or the like.

When the dial is displayed by sliding the pointer, the pointer is attached to a slider that moves along the guide. For example, in the apparatus shown in FIGS. 1 and 2, the pointer 1 is integrally formed with the arm 3 of the slider 2 so as to form an L-shape. As is well known, the slider 2 has a U-shaped clamping piece 6 that clamps a guide rib 5 formed on the back surface of the internal board 4, and the pointer 1 passes through a slit-shaped guide hole 7 to the operation panel 8. It is installed so as to face the dial window 9, but in this case, as mentioned above, the pointer 1
Since the guide hole 7 is formed integrally with the slider 2, a notch 10 for attaching and detaching the slider 2 to and from the guide rib 5 is bored on one side of the guide hole 7. That is, the slider 2 is inserted through the notch 10 so that the arm 3 and pointer 1 protrude forward from the guide hole 7, and is attached from the side of the guide rib 5. In addition, in the figure, 1
1 is a dial rope hook part. However, in this device, if the dial thread is broken due to forced operation of a knob (not shown), the slider 2 may come off from the notch 10 and fall off. Furthermore, if the slider 2 is made of metal, there is a risk of short-circuiting due to contact with live electrical parts or the like. On the other hand, in the devices shown in FIGS. 3 and 4, the slider 2 and the pointer 1 are formed as separate parts, and the arm 3 of the slider 2 is
The pointer 1 is attached to the arm 3 by fitting hooks 13, 13 provided at the upper edge of the pointer 1 into attachment holes 12, 12 formed at the tip. Therefore, in this device, there is no need to provide the notch 10 as described above, so even if the dial thread breaks, the slider 2
will not fall off, but if the pointer 1 is damaged, it will be difficult to replace it, and the arm 3
It took time and effort to attach the pointer 1 to the holder, and the assembly workability was poor.

Therefore, the purpose of this invention is to provide a pointer attachment device that allows the slider including the pointer to be easily attached and removed, while also being able to reliably prevent the slider from falling off due to cutting of the dial thread. .

Hereinafter, embodiments of this invention will be described with reference to the accompanying drawings. In the drawings, the same parts as in FIGS. 1 to 4 are given the same reference numerals.

As shown in FIGS. 5 and 6, the pointer attachment device 14 according to this invention has a guide hole 7 bored in the internal substrate 4, similar to the conventional device described above, A guide rib 5 is provided in a protruding manner. The slider 2 attached to the guide rib 5 has a pair of clamping pieces 6, 6 formed to clamp the guide rib 5, and a pair of clamping pieces 6, which protrude forward from the guide hole 7 (towards the operation panel 8 shown in FIG. 1). It includes a plate-shaped arm 3 formed so as to be shaped as shown in FIG. A notch 10 is formed on one side of the guide hole 7 for pushing the arm 3 and the pointer 1 forward when the slider 2 is attached. In this invention, on the back side of the internal board 4, a U is provided on the side edge of the notch 10.
One piece of the spring plate 15 bent into a letter shape is arranged in a row, and the other piece of the spring plate 15 is extended so as to face the center of the notch 10. In this example,
The internal board 4 and the spring plate 15 are integrally formed of synthetic resin.

In the above configuration, when the slider 2 is attached to the guide rib 5, the spring plate 15 is elastically deformed laterally as shown by the solid line in FIG. 1 to the front and slide the clamping pieces 6, 6 from the sides of the guide rib 5 to attach them. In this way, when the slider 2 is attached to the guide rib 5 and moved to the right in the figure, the spring plate 15
returns elastically to its original state as shown by the imaginary line. In this state, even if the dial rope breaks, for example by forcefully operating a knob (not shown), the slider 2 is prevented from moving out of the notch 10 because the spring plate 15 restricts its movement. However, the spring plate 15 is constructed so as not to be easily deformed by the maximum tension applied to the dial rope. Furthermore, when removing the slider 2, the spring plate 15 is compressed laterally, and the notch 10
The slider 2 can be removed from the wide space provided.

Note that the spring plate 15 may be screwed to the internal board 4. Further, the spring plate 15 has a cutout portion 1
It may be connected to the upper edge or lower edge of 0.
Furthermore, the shape of the spring plate 15 is a flat plate, and
It may simply extend from the edge of the notch 10 to the central opening.

As is clear from the description of the embodiments described above, according to this invention, a spring plate that acts elastically on the slider is provided at the edge of the notch for attaching and detaching the slider, which is bored on one side of the guide hole. By providing this, it is possible to reliably prevent the slider from coming off from the notch when the dial rope breaks. Furthermore, by elastically deforming the spring plate, the slider can be easily attached and detached.
