Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a switch switching device for a switch in which switching is performed by sliding a slider, and in particular, the switch and the operation button are arranged apart from each other. The present invention relates to a switch switching device suitable for use when

(B) Prior Art In electronic devices, switches are often placed on a printed circuit board separated from the operation panel due to circuit layout. As such an electronic device, a tape recorder, which is an audio device, is well known. In the case of a tape recorder, for example, as shown in Japanese Utility Model Application No. 51-115004, the recording button and the recording playback are controlled by a motion transmission member. and a changeover switch, the force applied to the recording button is transmitted via the motion transmission member to a slider of a recording/playback changeover switch provided at a predetermined position on the printed circuit board, and the slider is The recording/playback switch is configured to be switched to the recording side by sliding the switch.

(c) Problems to be solved by the invention However, the above-mentioned motion transmission member usually has a flexible frame made of a synthetic resin material,
A flexible sliding body made of a thin metal plate that slides inside the frame, or as shown in, for example, Japanese Utility Model Application No. 56-141325,
Since the spring and the wire were connected, the former method was expensive, and the latter method was troublesome to connect and had poor workability.

(d) Means for solving the problem The present invention was made in view of the above points, and includes a switch in which switching is performed by sliding a slider, and one end of which is connected to the slider of the switch. a sliding member that comes into contact with the button and slides in response to the operation of the operation button; a supporting piece having a sliding groove in which the sliding member slides; and the sliding member is supported by the supporting piece. a supporting member for supporting the sliding member, a notch is formed in the side of the sliding member, the notch part of the sliding member is inserted into the sliding groove, and the sliding part of the sliding member in the sliding groove is provided with a notch. A guiding opening is formed, and a deep portion having a width narrower than the opening is formed at a position deeper than the sliding portion of the sliding groove.

(E) Function This invention forms a notch on the side of the sliding member, and the notch part of the sliding member is inserted into the sliding groove, and an opening is formed in the sliding groove leading to the sliding part of the sliding member. By forming a deep part narrower than the opening at a position deeper than the sliding part of the sliding groove, when the sliding member is inserted into the sliding groove, The contact area between the sliding member and the support piece on which the sliding groove is formed is reduced by preventing the sliding member from reaching the deep part of the sliding groove, and the sliding groove of the sliding member is This makes it easy to insert into the .

(F) Embodiment Figures 1 and 2 show an embodiment of the present invention, and are a plan view and a front view, respectively. a rotating member that rotates in the direction of arrow A around shaft 2;
3 is a sliding member whose one end is in contact with the pressing portion 1a of the rotating member 1; 4 is a support member that is screwed and fixed to the base 5 and supports the sliding member 3; 6 is a sliding member; This is a non-lock type switch in which the slider 6a, which is switched by the switch, is always held in a protruding state by a spring. As shown in FIG. 3, the sliding member 3 is constituted by a metal plate having both ends folded back and two pairs of opposite notches 7 and 8 formed at predetermined positions on both sides. has been done. Further, as shown in FIG. 3, the support member 4 has support pieces 9 and 10 formed in a folded shape at positions corresponding to the notches 7 and 8 of the sliding member 3. It is constituted by a metal plate in which sliding grooves 11 and 12, in which the sliding member 3 slides, are formed in 9 and 10. By the way, the sliding groove 11
and 12 have the same shape, and each has an opening that matches the width of the portion of the sliding member 3 where the notches 7 and 8 are provided, and the notches 7 and 8 of the sliding member 3 are not provided. It has a three-tiered shape, consisting of a central portion that matches the width of the opening, and a deep portion that is narrower than the opening.

When assembling, first place the support member 4 on the base 5.
The notches 7 and 8 of the sliding member 3 are aligned with the supporting pieces 9 and 10 of the supporting member 4, respectively.
are inserted from the front into the sliding grooves 11 and 12 of the support pieces 9 and 10, respectively. Here, the width b of the deep portion of the sliding grooves 11 and 12 is smaller than the width a of the opening of the sliding grooves 11 and 12, as shown in FIG. The width of the portion where the notches 7 and 8 are formed is the same as that of the sliding groove 1.
Since the width a of the openings 1 and 12 is approximately the same, the sliding member 3 is formed in the sliding grooves 11 and 1.
It is not inserted to the deep part of 2. Therefore, the sliding member 3 is inserted only to the center of the sliding grooves 11 and 12, so when the sliding member 3 reaches the center of the sliding grooves 11 and 12, the sliding member 3 is inserted into the sliding grooves 11 and 12. A force in the direction of arrow C in FIG. 3 is applied to 3.
Here, the width of the central portions of the sliding grooves 11 and 12 is approximately the same as that of the portion of the sliding member 3 where the notches 7 and 8 are not formed, and the width is slightly larger than that portion. Therefore, by applying a force in the direction of arrow C, the sliding member 3 is inserted into the center of the sliding grooves 11 and 12. For that reason,
Since the positions of the notches 7 and 8 of the sliding member 3 are shifted from the positions of the sliding grooves 11 and 12, respectively, the sliding member 3 is slidably supported by the support member 4. If you are in a situation like this,
Next, the assembly is completed by attaching the switch 6 fixed to the printed circuit board 14 to a predetermined position. In this case, one end of the sliding member 3 is brought into contact with the slider 6a of the switch 6, and the sliding Child 6
The pressing portion 1a of the rotating member 1 is rotated in the opposite direction of the arrow A by the elastic force of the rotating member 1.
The switch 6 is positioned so that the other end of the sliding member 3 comes into contact with the switch.

Now, when an operation button (not shown) is operated to rotate the rotating member 1 in the direction of arrow A about the shaft 2, the sliding member 3 slides in the direction of arrow B. Therefore, the slider 6a of the switch 6 also slides in the direction of arrow B, and the switch 6 is switched. Here, the position of the switch 6 is set so that even if the switch 6 is switched, the notches 7 and 8 of the sliding member 3 do not reach the positions of the support pieces 9 and 10 of the support member 4, respectively. The sliding member 3 will not fall off the support member 4 due to switching of the switch 6.

Once the switch 6 has been changed, the operation of the operation button is released. Then, the slider 6a of the switch 6 returns in the opposite direction of arrow B due to the elastic force, so the sliding member 3 also returns in the opposite direction of arrow B, and the rotating member 1 moves in the opposite direction of arrow A around shaft 2. direction and return to its original state.

By the way, the contact portions of the sliding member 3 with the supporting member 4 are only the supporting pieces 9 and 10, and the sliding grooves 1 in which the sliding member 3 of the supporting pieces 9 and 10 slide.
1 and 12 have an opening and a deep portion, so the contact portion is extremely small. Therefore, the sliding member 3 slides smoothly according to the force applied to both ends.

(g) Effects of the invention As described above, the present invention prevents the sliding member from reaching the deep part of the sliding groove, so it is possible to make the sliding movement of the sliding member smooth and to prevent the sliding member from reaching the deep part of the sliding groove. It is possible to provide a switch switching device in which the sliding member can be easily inserted into the sliding groove, the switching operation feeling of the switch is good, and the assembly work is easy.
