DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, a mounting structure of a multiple operation button body of this kind is disclosed in, for example, Japanese Utility Model Publication No. 5-38503.
No. (H01H 13/70). As shown in FIG. 3, the configuration of the related publication includes, as shown in FIG. 3, a multiple button group 10 having a push button 1, a push knob 2, a hook-shaped piece 3, a U-shaped projecting 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 projecting piece 4 are inserted,
Second through hole 8 into which hook 3 is inserted, positioning boss 5a
Are formed, 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 4a of the push button 1 is in the locking step 11a, the positioning boss 5a is in the third through hole 9, and the hook-shaped piece 3 is in the The two through holes 8 are respectively penetrated and locked. At this time, the connecting piece 5 and the positioning stopper 6 of the multiple button group 10 are
It is sandwiched between 2 and 13.

[0004]

In the above-described construction, a gap g (see FIG. 3) is generated between the push buttons, and the appearance is reduced, and the structure on the panel side is complicated, so that the mold is not provided. The production cost is increased, which is an adverse effect on cost reduction of products. Therefore, in the present invention, in order to make the structure in which the multiple button body can be attached to the operation panel with one touch, both the multiple button body and the operation panel have relatively simple mold structures and can be manufactured at low cost. Provide mounting structure.

SUMMARY OF THE INVENTION According to the present invention, there is provided an operation button mounting structure in which a plurality of rows of a plurality of button bodies having operation buttons connected to a series of support portions via thin hinges are arranged adjacent to each other. A first having a first through hole and holding the supporting portion;
An operation panel including a second groove, a second through hole, and a third through hole for inserting a switch pressing piece;
And a button pressing portion connected to the support portion via the hinge, the switch pressing portion connected to the pressing portion, and an individual opposing and adjacent between the multiple button bodies. A first multiple button body including a first rib protrudingly formed by a general cavity core butting mold structure on an adjacent opposed side surface of the button, and a first locking piece provided on the support portion,
A button pressing portion connected to the support portion via the hinge,
A switch pressing piece connected to the pressing portion, a second rib formed opposite to the first rib on an adjacent opposing surface side of each of the buttons adjacent to each other between the multiple button bodies, And a second multiple button body having a locking piece, wherein the support portion of the first multiple button body is fitted into the first groove of the operation panel, and the first multiple button body is fitted with the first multiple button body. The first locking piece of the first multiple button body is inserted and locked into the first through hole of the groove, and the support of the second multiple button body is inserted into the second groove of the operation panel. The first locking piece of the second multiple button body is inserted and locked in the first through hole of the second groove, and the second locking hole is inserted into the second through hole. When one side surface of each button of the second multiple button body is pressed by inserting and locking the locking piece of the second multiple button body, the second rib comes into contact with the first rib, and the second Prevents multiple buttons from falling off It is so.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment will be described below with reference to the drawings. 1 is an exploded perspective view, FIG.
Is an assembled sectional view. In the figure, reference numeral 20 denotes a first multiple button body in which three first operation buttons 21 are connected. The first
The multiple button body 20 of the plurality of first locking pieces 22, 22, ...
And a thin hinge 24, 24
And operation buttons 21 and 21 connected to the support unit 23 via the. The first operation button 20 includes 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 denotes a second multiple button body to which three second operation buttons 26 are connected. The multiple button body 25 includes a support portion 23 on which a plurality of first locking pieces 22 are formed and a second operation connected to the support portion 23 via thin hinges 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 formed integrally. The second rib 26c is formed at a position facing the first rib 21c.

Reference numeral 30 denotes an operation panel. The operation panel 3
0, a groove 32 having first through holes 31, 31,.
32, the second through holes 34, 34,...
Are integrally formed. The groove 32
The recess 32 may be formed in the operation panel 30 to form the groove 32, but the ribs 33 may be formed in parallel as shown in the figure.

The above-mentioned multiple buttons 20 and 25 are connected to the operation panel 3
, 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,
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 penetrated 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 around the support portion 23, but the second rib 26c Abuts against the first rib 21c of the operation button 21 and does not rotate more than a predetermined amount. Further, even if an external force is intentionally applied from the direction A in the figure, the ribs 21c and 26c abut against each other, so that
The concern that the second operation button 26 will fall off is eliminated. When the multiple button bodies 20 and 25 are removed, the first and second locking pieces 22, 22,.
It is only necessary to release the lock at 7,. Further, the first multiple button body 2
Even if the second locking piece 27 is not provided on the outer case 0, the outer first multiple button body 20 is prevented from falling off, and the gap g between the multiple button bodies 20 and 25 can be minimized. Becomes

[0011]

According to the above configuration, when the multiple button body is arranged in a plurality of rows, the gap between the adjacent buttons in front, rear, left and right can be arbitrarily designed, and the gap between the aligned rows of the buttons can be reduced. It can be made as small as possible, and looks good in design.
Also, it is possible to assemble with one touch, and it is difficult to remove from the button mounting surface, but it can be easily removed from the back surface, which is excellent in workability of mounting and removing.
