Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching an operation button attached to a front panel in an electronic device such as a video tape recorder.

[0002]

2. Description of the Related Art Conventionally, a mounting structure for a multi-operation button body of this kind has been disclosed, for example, in Utility Model Publication No. 5-38503.
No. (H01H 13/70). As shown in FIG. 3, in the configuration of the publication, the multiple button group 10 includes a push button 1, a push knob 2, a hook-shaped piece 3, a U-shaped protruding piece 4 having a hook portion 4a, and a positioning boss 5a. The connecting piece 5 and the positioning stopper 6 are integrally formed. The panel 14 has a first through hole 7 into which the pressing knob 2 and the protruding piece 4 are inserted,
Second through hole 8 into which hook-shaped piece 3 is inserted, positioning boss 5a
Is formed with a third through hole 9 into which is inserted, a locking projection 11 having a step portion 11a, and ribs 12 and 13.

When the above-mentioned multiple button group 10 is fitted to the panel 14, the hook portion 4a of the push button 1 is in the locking step portion 11a, the positioning boss 5a is in the third through hole 9, and the hook-shaped piece 3 is in the first position. Each of the two through holes 8 is inserted and locked. At that time, the connecting piece 5 and the positioning stopper 6 of the multiple button group 10 are not separated by the rib 1 of the panel 14.
It is sandwiched between 2 and 13.

[0004]

In the above-described structure, a gap g (see FIG. 3) is formed between the push buttons, the appearance is deteriorated, and the structure on the panel side becomes complicated. Manufacturing costs are high, which is an obstacle to cost reduction of products. Therefore, in the present proposal, in order to attach the multiple button body to the operation panel with one touch, both the multiple button body and the operation panel have a relatively simple mold structure and can be manufactured at low cost. Provide a mounting structure.

[0005]

[Means for Solving the Problems] The structure of the present invention is an operation button attachment structure for arranging a plurality of multiple button bodies in which a plurality of operation button bodies are connected to a series of supporting portions through thin hinges so as to be adjacent to each other. An operation panel having a plurality of rows of groove portions having a first through hole for holding the support portion, a second through hole, and a third through hole for inserting a switch pressing piece, and a support portion. A button pressing part connected to the supporting part via the hinge, a switch pressing part connected to the pressing part, and a plurality of button parts, which are adjacent to each other between the multiple button bodies. First multiple button body provided with a first rib protrudingly formed on a side surface adjacent to and adjacent to the button, and a support portion provided with a first locking piece and connected to the support portion via the hinge. Button pressing portion, a switch pressing piece connected to the pressing portion, and an adjacent pair of individual buttons that are adjacent and facing each other between the multiple button bodies. A second multiple button body including a second rib formed on the surface side so as to face the first rib and a second locking piece, and the first multiple button in the groove portion of the operation panel. While fitting the support portion of the body, inserting and locking the first locking piece in the first through hole, fitting the support portion of the second multiple button body in the groove portion of the operation panel, and By inserting and locking the first locking piece into the first through hole and inserting and locking the second locking piece into the second through hole, the individual button of the second multiple button body is When the one side surface is pressed, the second rib comes into contact with the first rib to prevent the second multiple button body from coming off.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment will be described below with reference to the drawings. 1 is an exploded perspective view, FIG.
FIG. 3 is an assembled sectional view. In the figure, 20 is a first multiple button body in which three first operation buttons 21 are connected. The first
The multiple button body 20 has a plurality of first locking pieces 22, 22, ...
Support portion 23 in which the hinge is formed, and thin-walled hinges 24, 24
The operation buttons 21 and 21 are connected to the support portion 23 via the. The first operation button 20 has a button pressing portion 21a.
And a switch pressing piece 21b and first ribs 21c, 21c protruding in a direction orthogonal to the pressing direction.

Reference numeral 25 is a second multiple button body in which three second operation buttons 26 are connected. The multiple button body 25 has a support portion 23 having a plurality of first locking pieces 22, 22 ... and a second operation connected to the support portion 23 via thin hinges 24, 24. The buttons 26, 26, ... The second operation button 26 includes a button pressing portion 26a and a switch pressing piece 26b.
And second ribs 26c, 26c protruding in the pressing direction,
The second locking pieces 27, 27 are integrally formed. The second rib 26c is formed at a position facing the first rib 21c.

Reference numeral 30 is an operation panel. The operation panel 3
0, the groove portion 32 having the first through holes 31, 31, ...
32, second through holes 34, 34, ..., And third through hole 3
5, 35, ... Are integrally formed. The groove 32
May form a groove in the operation panel 30 by forming a recess, but may also form the ribs 33, 33 in parallel as shown in the figure.

The operation panel 3 is provided with the multiple button bodies 20 and 25 described above.
In order to assemble to 0, the first locking pieces 22, 22, ... Of the first multiple button body 20 are inserted into the first through holes 31, 31 ,. Then, the switch pressing pieces 21c, 21c, ... Are inserted into the third through holes 35, 35 ,. Next, the first locking piece 22 of the second multiple button body 25,
, 22 are inserted into the first through holes 31, 31, ..., the support portion 23 is fitted into the groove portion 32, and the second locking pieces 27, 2 are inserted.
.. are inserted into the second through holes 34, 34, ..., the switch pressing pieces 26b, 26b ,.
5, 35, ...

As shown in FIG. 2, when the second operation button 26 is pressed, the operation button 26 rotates counterclockwise about the supporting portion 23 as a fulcrum, but the second rib 26c moves to the first position. The abutting abutment against the first rib 21c of the operation button 21 does not rotate more than a predetermined amount. Further, even if an external force is intentionally applied from the direction A in the drawing, both ribs 21c and 26c abut against each other,
The concern that the second operation button 26 will fall off is eliminated. When removing the multiple button bodies 20, 25, from the back surface of the operation panel 30, the first and second locking pieces 22, 22 ,.
All you have to do is to release the locks of 7, ... Furthermore, the first multiple button body 2
It is possible to prevent the outer first multiple button body 20 from falling off and to minimize the gap g between the multiple button bodies 20 and 25 without providing the second locking piece 27 at 0. Becomes

[0011]

As described above, when the multiple button bodies are arranged in a plurality of rows, the gap between the buttons adjacent to each other in the front, rear, left, and right can be arbitrarily designed, and the gap between the rows of the buttons can be reduced. It can be made as small as possible, and it looks good in terms of design.
In addition, it is possible to assemble with one touch and it is difficult to remove from the button mounting surface, but it is possible to easily remove from the back surface, which has an excellent workability of mounting and removing.
