BACKGROUND OF THE INVENTION The present invention relates to a panel attaching / detaching mechanism in electronic equipment.

[0002]

2. Description of the Related Art Conventionally, in an on-vehicle acoustic device having a front panel detachably provided, as shown in FIGS. 4 to 6, a recess 11b is provided in a main body panel 11a of a main body 11 of the audio device.
Engaging recesses 11c and 11d are provided on the left and right sides of the recess 11b.

On the panel 12 fitted in the concave portion 11b, operation knobs, a display section, and the like are provided at positions other than a hole 12b for inserting a cassette tape.

When the panel 12 is mounted on the main body panel 11a, the projection 12a provided on the left side of the panel 12 is fitted into the recess 11c, and then the right end is pushed into the main body panel 11a. The lock claw 14 provided on the right side comes into contact with the corner of the main body panel 11a and enters the panel 12, and projects to lock the panel 12 when facing the recess 11d.

When the panel 12 is to be removed,
Push the eject knob 13 provided on 12 to lock the claw 14
Was inserted into the panel 12, and the panel 12 was removed in the reverse order of the mounting.

However, the above-mentioned conventional panel attaching / detaching mechanism is incorporated in a panel to which the eject knob is attached and detached. When the eject knob is pushed, the lock is released, but the panel is pushed in with this and the panel is taken out. The operation was contrary to the above, so the panel could not be removed smoothly.

Further, since the eject knob is provided in the panel, the area for arranging the other knobs and the display section is reduced.
It was restricted by design.

The present invention has been made in view of the above points, and has as its object to provide a panel attaching / detaching mechanism which can eliminate the drawbacks of the conventional example, can be easily removed, and can use a wide panel surface. Where you do it.

[0009]

According to the present invention, there is provided a panel attaching / detaching mechanism for an electronic apparatus having a panel detachably provided in a front concave portion of a main body, wherein the slider is supported so as to be pushed back to one side of the main body, An eject knob attached to the slider and provided on a front surface of the main body, and supported by the main body such that when the eject knob is pressed, the eject knob is actuated by the slider and pivots in a direction in which the engagement with the panel is released. A lock lever, a first engagement recess provided near one side of the panel so as to engage with the lock lever, and a front recess provided on the other side of the panel. A projection that engages with the second engagement concave portion pushes the eject knob to release the engagement between the lock lever and the panel and remove the panel.

[0010]

According to the present invention, since the eject knob is provided on the main body, the detachable panel can be easily removed without affecting the removal of the detachable panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a panel attaching / detaching mechanism according to the present invention will be described with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a main body of an on-vehicle acoustic device whose front panel is detachable, and 1a denotes an escutcheon provided on the front of the main body 1. Reference numeral 1b denotes a recess surrounded by the escutcheon 1a, on which a panel is mounted. Reference numeral 1c denotes a second engagement recess provided on the inner left side of the escutcheon 1a, and a projection of the panel is engaged. 1d is a hole for the eject knob 3 provided in the escutcheon 1a.

Reference numeral 2 denotes a panel detachably provided in the recess 1b, 2a
Is a protrusion provided on the left side of the panel 2 so as to engage with the second engaging concave portion 1c of the escutcheon 1a, and 2b is a first engaging member provided near the right side of the panel 2 so as to engage with the hook 7b. Recess,
2c is a side wall that forms the first engagement recess 2b.

Reference numeral 4 denotes a slider to which the eject knob 3 is attached and which is supported by two bosses 5 standing upright on the main body so as to be pushed back to the right side of the main body 1; , 4b is an operating part that operates the lock lever,
A spring 6 biases the slider 4 toward the panel 2.

Reference numeral 7 denotes a fulcrum boss 8 which is operated by the slider 4.
The lock lever 7a rotates about the center of the panel 2, 7a is an upwardly inclined portion which is actuated by sliding of the operating portion 4b, and 7b is the first portion of the panel 2.
Hook engaged with the engaging recess 2b. 7c is an inclined portion of the hook 7b.

The attachment and detachment operation and operation of the panel attachment / detachment mechanism of the present invention configured as described above will be described.

When the panel 2 is mounted on the main body 1, the projection 2a provided on the left side of the panel 2 is fitted into the second engagement recess 1c provided on the inner recess 1b of the escutcheon 1a. Is pushed into the body 1 side, the side wall 2c of the panel 2
Abuts on the inclined portion 7c provided on the hook 7b of the lock lever 7, and rotates the lock lever counterclockwise. When the side wall 2c of the panel 2 passes through the hook 7b, the lock lever 7, which is urged clockwise by a spring (not shown), turns clockwise, and the hook 7b engages with the first engagement recess 2b. Then, the panel 2 is locked.

When the panel 2 is to be removed from the main body 1, the eject knob 3 is pressed. Thereby, the slider 4
The operating portion 4b slides on the inclined portion 7a of the lock lever 7 to rotate the lock lever 7 counterclockwise. For this hook
The engagement between the first engagement recess 2b of the panel 2 and the first engagement recess 2b of the panel 2 is released, so that the panel 2 can be removed smoothly in the reverse procedure of the mounting. When the eject knob 3 is released, the eject knob 3 is urged toward the panel 2 by the spring 6, and returns to a predetermined position where the boss 5 and the edge of the long hole 4a are in contact.

[0019]

According to the panel attaching / detaching mechanism of the present invention, since the panel is constructed as described above, no force is applied to the panel even when the eject knob is pushed, so that the panel can be removed smoothly.

Also, it is not affected by the eject knob,
Since the panel surface can be used freely, you can design freely.

In addition, it has excellent features such as simple structure and easy implementation because it can be constructed at low cost.
