[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. In these figures, the same components as those shown in FIGS. 6 and 7 are denoted by the same reference numerals, and description thereof will be omitted.

1, 2 and 3, the cover 23 of the cover device 21 is provided with an operation section 24 for operating the hook at the end in the length direction and near the hook 13. The operation unit 24 is configured by a notch.
Further, the cover is provided with a bending portion 26 that bends so that a portion between the portion where the operation portion 24 of the cover is formed and the portion facing the operation portion projects upward. The curved portion 26 is provided with a groove 27 for reducing the thickness of the plate, reducing the mechanical strength, and facilitating the bending of the cover.

In such a cover device 21, when the cover 23 is mounted on the housing 2, the cover 23 is placed on the fitting portion 7 and both ends of the cover 23 are directed toward the fitting portion 7. The cover 23 is bent by pressing
6 is curved so as to project upward,
The hook 13 is inserted into the hole 9 and the flange 14 of the hook 13 is inserted.
And the projection 15 are engaged, and the cover 23 is fixed to the housing 2.

When the cover 23 is detached from the housing 2, a sharp tip such as tweezers is abutted against the operating portion 24 of the cover 23, and the cover 23 is moved upward by the curved portion 26. By bending so as to be in a protruding state, the engagement between the flange 14 and the projection 15 is released, and the cover 23 is detached from the housing 2.

As described above, the cover 23 of the cover device 21 is provided with the operating section 24 for hitting a sharp tip such as tweezers. An appropriate space is secured, and the cover 23 can be detached without damaging the cover 23 and the edge of the fitting portion 7.

Further, since the cover 23 is provided with a groove 27 which is a curved portion 26 in which the thickness of the cover is reduced and the mechanical strength is weakened in order to bend the cover 23, the cover 23 is used when attaching and detaching the cover 23. Also, the force applied to the cover 23 is small, and the cover 23 can be detached without being damaged.

Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 4 is a view for explaining the second embodiment, and is a view showing a cover 31. FIG.

In the second embodiment, the first embodiment
Only the points different from the above embodiment will be described.

Referring to FIG. 3, a hole 33 is provided in the curved portion 32 of the cover 31.

Since the cover 31 is provided with the hole 33 which is the curved portion 32, the mechanical strength of the curved portion 32 of the cover 31 is slightly weaker than that of the cover 23 in the first embodiment. Since the cover 31 is easily curved, less force is applied to the cover 31 and the cover 31 can be easily attached and detached without being damaged.

Next, a third embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a view for explaining the third embodiment, and is a view showing a cover 41.

In the third embodiment, the first embodiment
Only the points different from the above embodiment will be described.

In FIG. 5, a concave portion 43 is provided in the curved portion 42 of the cover 41.

Since the cover 41 is provided with the concave portion 43 serving as the curved portion 42, the mechanical strength of the curved portion 42 of the cover 41 is slightly weaker than that of the cover 23 in the first embodiment. Since the cover 41 is easily curved, less force is applied to the cover 41,
The cover 41 can be easily detached without being damaged. Further, since the mechanical strength of the curved portion 42 of the cover 41 is slightly higher than that of the cover 31 in the second embodiment, it is possible to prevent the curved portion 42 from deteriorating.
The life of the cover 41 can be extended.

The technical scope of the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention. For example, in the embodiment, the cover device is provided in an electronic device including a housing in which a plurality of cases are screwed. Applicable. Further, although the operation unit is a cutout, it may be a hole. Further, the curved portion may be formed with a number of small holes in order to reduce the mechanical strength. Further, the first embodiment and the third embodiment
In the above embodiment, the curved portion is provided on the lower surface of the cover, but may be provided on the upper surface of the cover. Furthermore,
In the first embodiment, the curved portion may have a plurality of grooves.

[0035]

As described in detail above, since the cover of the cover device of the present invention is provided with an operation portion for operating a hook for inserting a sharp-pointed object, the cover and the casing are provided. The cover can be detached without damaging the edge of the fitting portion of the body.

The cover is provided with a bending portion for bending the cover. The cover bends with a relatively small force, and the cover is easily disengaged from the housing. Can be removed.

Further, since the curved portion of the cover can be formed in a simple shape such as a groove, a hole, or a convex, the production of the cover device is simple and the production cost can be kept low.
