Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to preventing a main body case from being damaged due to opening and closing of a cover of an operation portion of a portable telephone.

[0002]

2. Description of the Related Art A structure for preventing a main body case from being damaged, which is employed in a conventional portable telephone, will be described below. FIG. 5 is a side view showing a structure for preventing a main body case from being damaged by opening and closing an operation unit cover of a conventional mobile phone. In the figure, 1 is a mobile phone main body case, 2 is an operation unit cover, 3 is a damage prevention cushion attached to the operation unit cover 2, 4 is an operation unit key switch, and 5 is a rotation of the operation unit cover 2. It is a hinge to be made.

Next, the operation will be described. FIG. 6 is a side view showing an example of the operation of a damage prevention structure incorporated in a conventional mobile phone. A damage prevention cushion 3 is attached near the tip of the operation unit cover 2 for protecting the operation unit key switch 4 of the body case 1 of the mobile phone, and when the operation unit cover 2 is closed, the cushion 3 is moved to the body of the mobile phone. Contact Case 1 first.

[0004]

A conventional portable telephone is
With the above-described configuration, a unique component called an anti-scratch cushion is required, and the work of attaching the anti-scratch cushion occurs, resulting in a decrease in work efficiency and an increase in cost. In addition, since another component called a scratch prevention cushion is attached, there is a possibility that peeling may occur.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and does not involve a decrease in working efficiency or cost, and does not involve the removal of a cushion for preventing damage to an operating portion of a mobile phone. The purpose is to prevent the body case from being damaged by movement.

[0006]

According to a first aspect of the present invention, there is provided a mobile phone configured to expose and use the main body operation section by rotating and opening a cover covering the main body operation section. In the telephone, a cushion integrally formed with an operation portion key switch made of an elastic material protruding from a front surface of the main body operation portion is protruded from a closed portion between the operation portion lid and the main body operation portion, and the lid is When the cover is closed, the lid comes into contact with the cushion.

In the portable telephone according to the second aspect of the present invention, the cushion is formed integrally with an operation portion key switch made of an elastic material protruding from the front surface of the main body operation portion, and is integrally formed with a body case made of a rigid material. It was done.

In the portable telephone according to the third invention,
The cushion functions as one of operation section key switches made of an elastic material protruding from the front surface of the main body operation section.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an essential part showing an example of the mobile phone of the present invention. In FIG. 1, 1 is a main body case of a mobile phone, 2 is an operation unit cover of the main body case 1, 3 is a cushion for preventing the main body case 1 from being damaged by the rotation of the 2, and 4 is a main body case 1 of the mobile phone. Key switches on the operation panel
Indicates a hinge for rotating the operation unit cover 2.

Next, the operation will be described. FIG. 2 is a partially sectional side view showing an example of the operation of the mobile phone of the present invention. The body case scratch-prevention cushion 3 integrally formed with the operation portion key switch 4 made of an elastic material of the mobile phone projects from the front surface portion of the operation portion front surface of the body case 1 made of the rigid material. Is body case 1
The main unit case is configured to hit the cushion 3 for preventing damage before hitting the surface of the operation unit, and is configured not to touch the operation unit key switch 4.

As a result, the operation unit cover 2 rotates about the hinge 5 and hits the anti-scratch cushion 3 prior to the operation unit surface of the main body case 1 of the portable telephone during the "close" operation, absorbing the impact. . When the operation unit key switch 4 is pressed, the first contact 6 attached to each key comes into contact with the second contact 7 arranged on the substrate 8 to operate.

According to the first embodiment, when the operation unit cover 2 of the mobile phone is closed, the operation unit cover 2 is formed integrally with the operation unit key switch 4 before the operation unit cover 2 contacts the main body case 1. By contacting the cushion 3, it is possible to easily prevent damage to the main body case due to the closing movement of the operation unit cover 2 without increasing the number of parts, and there is an effect that cost does not increase.

Embodiment 2 FIG. FIG. 3 is a partial cross-sectional side view showing a mobile phone according to Embodiment 2 of the present invention. In the first embodiment, only the operation part key switch and the body case damage prevention cushion are integrated, and are different from the body part of the mobile phone. However, these parts are composed of the body part case made of resin material and the operation part key made of elastic material. As a switch integrated product 10, it may be an integrally molded product, and the same effect is obtained.

According to the second embodiment, the cushion 3 for preventing the body case 1 from being damaged due to the closing movement of the operation unit cover 2 of the mobile phone is integrally formed with the main unit case 1 together with the operation unit key switch 4, and By using the unit key switch integrated product 10, it is possible to obtain the same effects as those of the first aspect of the invention, and also to obtain effects such as reduction in the number of parts, improvement in workability, and cost reduction.

Embodiment 3 FIG. 4 is a partial sectional side view showing a structure for preventing a cellular phone from being damaged according to Embodiment 3 of the present invention. In the first embodiment, the body case damage prevention cushion 3 is not used for other purposes. However, in the third embodiment, as shown in FIG. For example, it can be operated as a power key or an operation unit cover opening / closing detection key.

According to the third embodiment, since the cushion 3 for preventing the main body case 1 from being damaged is shared with the operation part key switch 4, there is an effect that the number of keys can be increased and multi-function can be supported.

In the above embodiment, two anti-scratch cushions 3 are provided symmetrically so as to face the free edge of the operation unit cover 2 at the time of closing rotation.
The operation unit lid 2 and the damage prevention cushion 3 may be brought into contact with each other at one place.

[0018]

According to the first aspect of the present invention, it is easy to prevent damage to the main body case due to closing movement of the operation unit cover of the portable telephone without increasing the number of parts by using a cushion formed integrally with the operation unit key switch. This has the effect of not increasing the cost.

According to the second aspect of the present invention, the cushion for preventing the main body case from being damaged by the closing movement of the operation section lid of the mobile phone is integrally formed with the main body case together with the operation section key switch. In addition to the effects described above, effects such as reduction in the number of parts, improvement in workability, and reduction in cost can be obtained.

According to the third aspect, the cushion for preventing the main body case from being damaged is shared with the key switch of the operation unit, so that the number of keys can be increased and multifunction can be achieved.
