Abstract

PROBLEM TO BE SOLVED: To reduce the thickness and weight as well as the material cost in the cover of a portable electronic device and improve the reliability of a product. SOLUTION: A projected line 20 is provided as a spacer on the inside of a cover 17 which is journaled rotatably on a main body 10 in the opening direction, while it is brought into contact with the parts other than the operation keys on the main body. Due to the projected line, the rigidity of the cover itself increases and the keys 5 and 6 are not depressed because the projected line works as a spacer.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for a portable electronic device such as a portable telephone.

[0002]

2. Description of the Related Art Portable electronic devices are often carried in clothes pockets or bags. Therefore, some portable telephones or electronic notebooks having an operation key have an openable / closable cover to prevent erroneous operation or protect keys. For example, in a mobile phone, there is a type in which a cover for covering a dial key or the like is foldable, and the cover is opened to a main body during a call.

A cover of a conventional foldable portable telephone will be described with reference to FIG.

The foldable portable telephone has a main body 2 including a function key 5, a dial key 6, a transmitter 7, a receiver (not shown), and a cover for covering the function key 5 and the dial key 6. And 1. The cover 1 has support holes 4, 4 that can be fitted to support shafts 3, 3 provided in the main body 2.
The support shafts 3, 3 are fitted in the support holes 4, 4 so that the support shafts 3, 3 can be rotated in the developing direction around the support shafts 3, 3.

[0005]

Generally, the cover 1 is formed so as to be able to cover in parallel with the surface 8 on which the function keys 5 and the dial keys 6 are provided. The thickness of the cover 1 itself varies depending on the product. For example, when the cover 1 has a small thickness, if the cover 1 is closed and a strong pressure is applied from outside, elastic deformation occurs, and there is a problem that the function keys 5 and the like are pressed. . When the cover 1 has a large thickness, the elastic deformation as described above is unlikely to occur. However, it is difficult to reduce the thickness and weight as compared with the case where the cover 1 is thin, and the material cost and the number of parts increase. Had become.

In view of such circumstances, the present invention provides a cover used for a portable electronic device such as a foldable portable telephone, which is capable of reducing material costs, reducing thickness and weight, and preventing erroneous operation of keys. It is intended to improve.

[0007]

According to the present invention, there is provided a portable electronic device provided with a ridge which abuts on a portion other than a key inside a cover rotatably supported in a developing direction with respect to a main body and functions as a spacer. The protrusion relates to a cover of a portable electronic device extending in the width direction of the cover, and the protrusion relates to a cover of the portable electronic device extending in a direction perpendicular to the width direction of the cover. Things.

By providing the ridge, the rigidity of the cover itself is increased, and even when external pressure is applied in a closed state, the ridge serves as a spacer, so that the gap between the cover and the main body is maintained. , No operation key is pressed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cover of a portable electronic device according to an embodiment of the present invention applied to a foldable portable telephone will be described below with reference to the drawings. 1 to 3, the same components as those shown in FIG. 5 are denoted by the same reference numerals.

First, the outline of the portable telephone shown in FIGS. 1 to 3 will be described. The mobile phone includes a receiver 11 and a display unit 1.
2, a main body 10 provided with a switch 13, a function key 5, a dial key 6, and the like. A transmitter 7 is provided on the shaft support portion 14, and a pair of left and right support shafts 3, 3 protrude from both left and right end surfaces.

The cover 17 has a notch 15 formed at the lower end thereof so as to be fitted to the shaft support 14, and a support hole 4 is formed at a position corresponding to the support shafts 3 on a surface in contact with the cut 15. , 4 are formed. By fitting the support shafts 3 and 3 into the support shaft holes 4 and 4, the cover 17 is connected to the main body 1 via the support shafts 3 and 3.
1 is rotatably supported in the unfolded state shown in FIG. FIG. 2 shows a state in which the cover 17 is not attached to the main body 10 for convenience.

The entire cover 17 is formed so as to have a convex surface bulging outward, and a ridge 20 extending in the width direction is provided inside the cover 17. The position where the ridge 20 is provided is a position where the cover 17 is closed and does not come into contact with the function keys 5 and the dial keys 6, for example, a position corresponding to a position between key rows.

By providing the ridge 20, the rigidity of the cover 17 itself increases, and even when external pressure is applied in a state where the cover 17 is closed, the tip of the ridge 20 is The gap between the cover 17 and the surface is maintained because it abuts between the key rows on the surface 8 on which the function key 5 and the dial key 6 are disposed, and serves as a spacer. 6 is not pressed.

Further, as shown in FIG.
The protrusions 21 may be provided at four inner corners of the cover 17.
The projections 21 are attached to the main body 1 with the cover 17 closed.
0 is a surface 8 on which the function key 5 and the dial key 6 are arranged.
Abutting together with the ridge 20 at a location other than the key, and maintaining the gap between the cover 17 and the surface 8, pressing is prevented even when the cover 17 is deformed. The ridge 20
Needless to say, the key pressing can be more effectively prevented by combining the projection 21 with the projection 21. The direction in which the step portions 18 and the protrusions 20 are provided may be a direction orthogonal to the direction shown in FIG.

[0015]

As described above, according to the present invention, the ridge functions as a spacer, maintains the gap between the cover and the main body, and prevents pressing of the key due to deformation of the cover.
The thickness and weight of the cover can be reduced, the material cost can be reduced, the function of preventing erroneous operation of the key can be improved, and the reliability of the product can be improved.
