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 having 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. . Further, when the cover 1 is made thick, the elastic deformation as described above is unlikely to occur. Had become.

The present invention has been made in view of the above circumstances, and provides a cover used for a portable electronic device such as a foldable portable telephone, which can reduce the material cost, reduce the thickness and weight, and prevent a key from being erroneously operated. It is intended to improve.

[0007]

Means for Solving the Problems The present invention is in contact in a location other than the key to the inner surface side of the cover which is rotatably journalled in the deploying direction relative to the body, provided with a convex portion that functions as a spacer The present invention relates to a cover of a portable electronic device.

By providing the convex portion, the rigidity of the cover itself is increased, and even if an external pressure is applied in a closed state, the convex portion serves as a spacer, so that the operation key is not 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. 7 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. The 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. The cover 17 is closed with respect to the main body 10 via the support shafts 3 and 3 by fitting the support shafts 3 and 3 into the support shaft holes 4 and 4 and is indicated by an arrow 16 from the folded state in FIG. It is rotatably supported in the deployment direction. 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 step 18 is provided substantially at the center.
By forming the step 18 as the cross-sectional shape of the cover 17, the second moment of area is increased, and the bending rigidity is increased. Furthermore, if the cover 17 itself is formed into a convex shape, the distance between the inner surface of the cover 17 and the function keys 5 and the dial keys 6 in a closed state increases, so that the cover 17
The function key 5 and the dial key 6 are less likely to be pressed or contacted even when elastic deformation occurs even when external pressure is applied.

Next, another embodiment of the present invention will be described with reference to FIG.

A ridge 2 extending in the width direction inside the cover 17
0 is provided. The position where the ridge 20 is provided depends on the position of the cover 1.
When the key 7 is closed, it is set to a position where it does not come into contact with the function key 5 and the dial key 6, for example, a position corresponding to a space between key rows.
By providing the ridge 20, the rigidity of the cover 17 itself increases, and even when an external pressure is applied in a state where the cover 17 is closed, the tip of the ridge 20 is
The function key 5 and the dial key 6 are not pressed down because they come into contact with each other between the key rows of the surface 8 on which the function keys 5 and the dial keys 6 are arranged, and serve as a spacer.

As shown in FIG. 5, protrusions 21 may be provided at four inside corners of the cover 17 instead of providing the protrusions 20. When the cover 21 is closed, the projection 21 abuts on a portion of the main body 10 other than the keys on the surface 8 on which the function keys 5 and the dial keys 6 are arranged, and a gap between the cover 17 and the surface 8 is formed. Therefore, pressing is prevented even when the cover 17 is deformed. Further, as shown in FIG.
It is needless to say that the key 21 can be more effectively prevented from being pressed by combining the projections 21 with the projections 21. The direction in which the steps 18 and the ridges 20 are provided may be a direction orthogonal to the direction shown in FIG.

[0016]

As described above, according to the present invention, the pressing of the key due to the deformation of the cover is prevented, so that the cover can be made thinner and lighter, the material cost can be reduced, and the function of preventing erroneous operation of the key can be provided. Improve the product reliability.
