Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for gripping a housing of a portable electronic device, mainly a communication device, an information processing device, an audio device and an image pickup device.

[0002]

2. Description of the Related Art Since a small portable communication device is used with one hand for a long time, it is required that the casing has a shape that allows a stable grip and a comfortable surface. In order to obtain a stable grip, it is conceivable that the case has a structure in which a wave is attached, but it is restricted by the design.

Further, tactile paints are generally used to improve the feel. However, the long-term effect cannot be expected because the paint wears heavily on the grip. Further, the coating thickness has a limit of about 50 μm, and there is a limit in obtaining the feel.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been proposed in view of the above-mentioned problems of the prior art, and when the housing is gripped, the housing can be reliably gripped, and it is difficult to slip.
An object of the present invention is to provide a portable electronic device that can make a finger or a hand portion where a force is easily applied to be soft, and that gives a finger-like feeling or a palm-like feeling and stability similar to rubber.

[0005]

In a portable electronic device according to the present invention, at least a part of the housing is made of a plastic member on the inside and an elastic member such as an elastomer on the outside by a double molding method. It is characterized in that a hole corresponding to a portion on which a finger or a hand touches is formed, and the hole is covered with the elastic member.

[0006]

As described above, by forming the hole corresponding to the part where the plastic member is touched by the finger or the hand and covering the hole with the elastic member, it is possible to surely grip the housing when gripping it. , You can make it hard to slip, and you can make the fingers or hands that are subject to force feel soft.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a portable electronic device of the present invention will be described below with reference to FIGS. FIG. 1 is a cutaway perspective view of an embodiment of a portable electronic device to which the present invention is applied. FIG. 2 is a partially enlarged sectional view of the embodiment of the present invention shown in FIG. FIG. 3 is a partially enlarged cross-sectional view for explaining a case where the case of the embodiment of the present invention shown in FIG. 2 is pressed with a finger. FIG. 4 is a side view of another embodiment of the portable electronic device to which the present invention is applied. FIG. 5 is a side view for explaining a case in which the case of another embodiment of the present invention shown in FIG. 4 is pushed with a finger.

FIG. 1 is a cutaway perspective view of an embodiment of a portable electronic device to which the present invention is applied. In FIG. 1, the case forming the portable electronic device of the present invention includes a first case 1 and a second case 2. The first housing 1 is provided with a display unit and an operation unit. The second casing 2 is a casing according to the present invention, and the casing 2 has an enlarged sectional view as shown in FIG.
By the double molding method, the inside is made of the plastic member 3 and the outside (formation surface) is made of an elastic member such as an elastomer.

The double molding method is a method of molding two different materials into two parts in two steps. In the present invention, the plastic member 3 is used as the structure of the housing 2, and the elastic member 4 is used as the appearance surface for covering the plastic member 3. The feature of the present invention resides in that the plastic member 3 is provided with a hole 3a corresponding to a portion which a finger or a hand touches when the housing is gripped by a hand. The hole 3a is covered only by the elastic member 4.

Since the plastic member 3 and the elastic member 4 have different cavities on the mold, this structure is possible. The hole 3a is only the elastic member 4, but is apparently flat. However, as shown in FIG. 3, when the portion is pressed by a finger, the elastic member 4 extends, dents, and when it is released, returns to the original plane.

FIGS. 4 and 5 are side views for explaining another embodiment of the portable electronic device to which the present invention is applied. FIG. 4 shows the three elongated holes 3b formed in the plastic member by broken lines. The appearance surface is the elastic member 4. As shown in FIG. 5, when the housing 2 is gripped (grasped) by the thumb, forefinger, middle finger, and ring finger, the elastic member 4 corresponding to the finger has the plastic member 3 with the long hole 3b formed therein. Therefore, dent. The touched part of the finger is soft, and the fingertips and palm can have a rubber-like favorable feeling and stability. When the grip is stopped and the finger is released, the elastic member 4 returns to the original plane.

[0012]

As described above, the portable electronic device according to the present invention makes it possible to securely grip the housing when it is gripped, to prevent slippage, and to make a finger or a hand portion where a force is easily applied feel soft. It has the effect of giving a pleasant feel and stability similar to rubber to the fingertips and palm.
