Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in operability of portable devices having an electronic mail function or an Internet connection function, such as a portable telephone, an electronic organizer, a PDA, and an HPC.

[0002]

2. Description of the Related Art As a conventional technique, here, Patent No. 30
The main points of a known mobile phone described in Japanese Patent No. 48228 will be described with reference to FIGS.

As shown in FIG. 6, a portable telephone has a speaker 22, a display window 23, a plurality of push buttons 24 and a microphone 25 on the front of a main body 21, and has a pull-out antenna 26 on the upper surface. A clip 27 is provided on the upper part of the back surface so that the clip 27 can be hooked and fixed to a clothes pocket or the like.

The operation of the mobile phone will be described with reference to FIG.

[0005] The outer shell of the mobile phone is held by the palm and the four fingers of the forefinger, middle finger, ring finger and little finger, and is operated by the thumb. Therefore, the distance between the holding portion indicated by a single ellipse on the palm and the operating portion indicated by a double ellipse on the tip of the thumb is short.

[0006]

In the above-mentioned conventional portable telephone, the distance between the palm holding portion and the operation portion at the tip of the thumb is short. Therefore, the user of the mobile phone has a small degree of freedom of the thumb, and is difficult to operate each push button 24.

Therefore, the present invention improves the drawbacks of the conventional portable telephone, and increases the degree of freedom of the thumb by increasing the distance between the holding section and the operation section at the tip of the thumb.
An object of the present invention is to provide a portable device such as a mobile phone which is easy to operate.

[0008]

The present invention employs the following means to solve the above-mentioned problems.

1. In a portable device having an operation unit on one surface of a main body, the portable device has a protrusion on at least one surface other than the one surface having the operation unit, and the protrusion is sandwiched between two fingers. A portable device having a function of holding the portable device.

[0010] 2. 2. The portable device according to claim 1, wherein a storage portion for storing the protrusion is provided on the main body, and the protrusion is attached to the main body by a hinge structure or a slide structure.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable telephone according to an embodiment of the present invention will be described with reference to FIGS.

As shown in FIGS. 1 and 2, the mobile phone has a display window 2, a speaker 3, a plurality of push buttons 4 and the like on the front of a main body 1, and is slightly lower than the center of the back. A projection 5, a storage section 6 in which the projection 5 is stored,
It has a hinge 7 that supports the projection 5 so that the projection 5 can rotate between the storage section 6 and a position protruding from the outer periphery of the main body 1.

When the user operates the mobile phone, the mobile phone shown in FIG.
As shown in FIG. 2 and FIG. 2, the protrusion 5 is made to protrude from the outer shell of the main body 1. Then, as shown in FIG. 5, the user clamps the projection 5 by each holding part shown by a single ellipse in the middle of the middle finger and the ring finger, and makes a double ellipse on the tip of the thumb. Each push button 4 is operated by the operation unit shown. Therefore, the distance between the holding part of the middle finger and the operation part at the tip of the thumb is long. Therefore, the user has a large degree of freedom of the thumb and can easily operate each push button 4.

When the user does not use the mobile phone, as shown in FIGS. 3 and 4, the protrusion 5 is rotated by 180 degrees with the hinge 7 as a fulcrum and stored in the storage 6.

In this embodiment, the projection 5 is housed in the housing 6 by the hinge 7, but can be modified as follows by changing the design. That is, instead of the hinge structure, a slide structure in which the protrusion 5 is linearly moved from the position protruding from the outer periphery of the main body 1 to the storage section 6 is employed.

Further, in the present embodiment, the projection 5 is provided on the back surface of the main body 1, but the design can be changed so as to be provided on the side surface of the main body 1. Further, it can be provided on two or more surfaces.

[0017]

As is apparent from the above description, the present invention has the following advantages.

1. Since the degree of freedom of the thumb is increased, the portable device can be easily operated.

2. Since a simple configuration in which the hinge structure or the slide structure of the projection, the housing, and the projection is provided on the main body of the portable device is adopted, the production is simple and the cost is low.
