Description

[Detailed Description of the Invention] The present invention relates to an operation button mounting device applied to, for example, a push button switch of an audio product.

In the case of the above-mentioned push button switches, those in which the area around the push button emits light when the switch is in the on state are often used. In such a device, it is conceivable to arrange a light source inside the push button and also arrange the control shaft of the switch, but this has the disadvantage that the shadow of the switch control shaft appears on the light emitting surface around the push button.

In order to solve this problem, it is possible to connect the push button and the switch control shaft with a piece with an L-shaped cross section and place a light source inside the L-shaped piece, but it is possible to move the L-shaped piece smoothly in the front and back direction. However, there are drawbacks such as difficulty in processing, complicated structure, and high cost.

This proposal was proposed in view of these points, and provides an extremely simple structure that allows for smooth movement, and that can transmit the movement of a push button to a switch control shaft, etc. via an L-shaped piece. The main purpose is to

When the control shaft 41 of the switch 39 is pressed in the direction of the switch 39 against the spring 45, the control shaft 41 is inserted into the switch 39 by a predetermined amount, and the switch 39
is switched to the on state and locked in that state in a known manner. This lock is again controlled by the control shaft 41.
is released in a known manner by being pressed in the direction of the switch 39, and the switch 39 is turned off. FIG. 5 shows the on state, and FIG. 2 shows the off state. Furthermore, when the switch 39 is turned off, the other switches 39 are turned on, and a known exclusion piece (not shown) is also moved in conjunction therewith. .

When the switch 39 is turned on, a corresponding predetermined circuit is turned on, and the corresponding lamps 35, 35, . . . are turned on. When the lamps 35, 35... are turned on, the corresponding light-emitting portions 13, 13... are irradiated through the L-shaped piece 11 and emit light.

FIG. 5 shows a case where the lower operation button 10 is pressed in the direction of the arrow 33. The operation button 10 and the L-shaped piece 11 are moved in the same direction by the pressing force in the direction of the arrow 33.
At this time, the L-shaped piece 11 has the rear end 34 of the side plate 31 connected to the hole 2.
The L-shaped piece 11 is moved in the direction of the arrow 33 while colliding with the opening surface 22 side of the lower side 21 of the hole 20, and the tip 46 of the top plate 30 of the L-shaped piece 11 sinks into the upper side 42 of the hole 20. Difficulty in movement in the direction of arrow 33 is minimized as much as possible.
When the operation button 10 is pressed in the direction of the arrow 33, the corresponding switch 39 is connected to the connecting piece 42 and the control shaft 4.
It is turned on via 1. Once the switch 39 is turned on, the pressing force on the operation button 10 in the direction of the arrow 33 is released, and the L-shaped piece 11 and the operation button 10
is moved together with the connecting piece 42 by the spring 37 in the direction opposite to the arrow 33 and returned. In this case as well, the L-shaped piece 11 is pushed into the hole 20 by the biasing force of the spring 37.
is abutted against the printed circuit board 27 side of the lower surface 21 of the
Moves smoothly without touching unnecessary surfaces. The lamp 35 corresponding to the switch 39 in the on state is lit, and it is possible to know which operation button 10 is in the on state. In this case, the connecting piece 42 and the control shaft 41 are separated.

To turn off the switch 39, the corresponding operation button 10 may be pressed again in the direction of the arrow 33, or another operation button 10 may be pressed in the same direction.

In the former case, the control shaft 41 is unlocked by pressing the operation button 10 further in the direction of the arrow 33 from the state shown in FIG. 42, the L-shaped piece 11 and the operation button 10 are moved in the opposite direction to the arrow 33. In this case, by making the biasing force of the spring 37 larger than the biasing force of the spring 45, the L-shaped piece 11
can be moved smoothly. In the latter case, the control shaft 41 is moved in the direction opposite to the arrow 33. Then, the lamp 35 is turned off, and the illumination of the light-emitting portion 13 is ended.

As described above, according to the present proposal, the operation button 10 is located on the top plate 3.
The operation button 10 is inserted into the through hole 15 of the wall surface 12, and the top plate 30 and the side plate 31 are inserted into the enlarged hole 20 formed on one side of the through hole 15. , the top plate 30 is inserted substantially parallel to the bottom surface 17 of the enlarged hole 20, is movable in the front and back directions of the wall surface 12, and is always urged in one direction of movement by the urging means 37, and the rear end of the side plate 31 is Since the portion 34 is biased so that it is constantly abutted against the opposing wall surface 48, the top plate 30 and the side plate 3 are prevented from causing unnecessary rattling.
1 and the operation button 10 are smoothly moved along the enlarged hole 20 and the hole 15. The top plate 30 and the side plates 31 can be made using less material and weight, can be made at low cost, and can be moved easily. Therefore, there is a practical effect such that the urging force of the urging means 37 can be reduced in proportion to this.

Further, by disposing a light source 35 between the top plate 30 and the side plate 31, and making one of the top plate 30 and the light-emitting portion 13 semitransparent and the other transparent or translucent, the light-emitting portion 13 can be made uniform. can be illuminated by a light source 35, the light source 35 can be placed using the space between the top plate 30 and the side plate 31, and a compact device can be provided.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications are possible. For example, the operation button 10 can be made of a metal material, or the wall surface 48 can be formed by using the hole 36 of the printed circuit board 27.

As explained above, in the operation button mounting device according to the present invention, since the side plate is constantly pressed against the inner peripheral wall surface of the enlarged hole by the biasing means, the side plate and the top plate, as well as the operation button connected to the top plate, The button moves smoothly without wobbling during movement, and there are no scratches between the operation button and the through hole. As a result, the operation button can be operated without impairing its marketability.

Furthermore, since the light source is disposed within the enlarged hole, the overall structure of the device can be made compact.
