Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal device having multiple functions such as input.

[0002]

2. Description of the Related Art In recent years, PDA (Personal Digital As
Mobile devices called sistants) are becoming popular. P
The DA has a main purpose of transmitting the input information to the personal computer, but there is also a DA which processes the information input by the PDA and transmits it. In addition, a key input is performed by attaching a separate keyboard that can be attached to an ordinary personal computer to this terminal device, but recently, in this type of terminal device, compactness is required, and the above-mentioned normal In the state where the 10 keys and the alphabet keys such as those of a personal computer are not provided on the front surface, the entire front surface is occupied by a wide display part, and the 10 keys and the alphabet keys are displayed on a part of the screen of the display part. It is designed to be input with a pen or the like.

[0003]

However, in such a conventional portable terminal device, it is possible to accurately and promptly input each key on the keyboard displayed in a relatively narrow area of the screen by using a pen. Had the problem of requiring extremely skilled technology.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve the above problems and provide a portable terminal device which enables accurate and quick key input with a compact device body.

[0005]

According to the present invention, there is provided a main body, a display portion provided on the front surface of the main body, a display portion provided on the front surface of the main body, on the periphery of the display portion and on the rear surface of the main body, and can be input by a finger. It is provided with a key input section.

Further, an input key for characters and symbols is provided on the rear surface of the main body, and a delete key is provided on the front surface side of the main body.

Further, there is a raised portion protruding from both sides of the main body, and the raised portion is provided near the key input portion or the second key input portion on the front surface of the main body.

[0008]

In the structure of the present invention, since the key input portion to be input by pushing with the finger is provided not on the display screen but on the front surface and the rear surface of the main body, it is possible to input with the finger.

Further, a delete key is provided on the front side to prevent deletion due to an operation error. Further, since the raised portion is provided, it is possible to input from the key input portion on the front surface of the main body while holding the raised portion with both hands.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a mobile terminal device of the present invention will be described below with reference to the drawings.

FIG. 1 is a view showing the front surface of this embodiment,
In the figure, 1 is a main body of the mobile terminal device, and 2 is a display unit which occupies almost 70% of the front surface of the main body 1. Denoted at 3 are raised portions provided so as to project from both side surfaces of the main body 1 in parallel with the main body 1.

Further, on both sides of the display unit 2 on the front surface of the main body 1, right side control key groups 4 such as a return key, a move key and a shift key are arranged on the right side, while a copy key and a delete (delete) are arranged on the left side. Key, escape key, d
A left side control key group 5 such as an sp (display) key is arranged. That is, all control keys are provided on the front surface.

Further, FIG. 2 shows the rear surface of this embodiment, and alphabet keys and 10 are provided on the left and right of the rear surface.
The input key groups 6 and 7 of the (numeric) key are arranged so as to be divided into right and left.

Here, the delete key is provided on the front surface instead of the rear surface on which the alphabet keys are provided. This prevents the input information from being deleted by pressing the delete key during input. This is because.

Further, referring to FIG. 3, in the portable terminal device of the present embodiment, as shown in the figure, each raised portion 3 is held by the palm of both hands.
Each thumb operates the control key groups 4 and 5 on the front surface of the main body so as to wrap around. Referring to FIG. 4, the shape of the raised portion 3 will be described.
It has an arcuate shape with the same thickness, and is provided so as to project outward from substantially the center of both side surfaces of the main body 1 in parallel with the surface of the display unit 2.

The raised portion 3 facilitates input by the fingers of the other hand while holding the main body with one hand.

Further, referring to FIG. 5, in the portable terminal device of the present embodiment, the display unit 2 has a display screen divided into upper and lower parts in the same manner as the conventional display unit, and the lower display unit 8 has alphabets. A key and a 10-key keyboard are displayed, and input can be performed by pressing these keys with a pen or the like, and the upper display unit 9 displays the input state. This is for enabling a user who is accustomed to key input on the display unit 2 to perform key input on the conventional display unit when he / she is not accustomed to key operation on the input keyboard of the present invention. Here, the input method includes a method using a pen from the display unit 2 and a method using a keyboard provided on the front surface and the rear surface. When the keyboard is displayed on the display screen of the display unit 2 by the display keys, Does not allow input using the keyboard provided on the rear surface.

Therefore, in this embodiment, it is possible to prevent the trouble of inputting with a pen from a small keyboard displayed as in the conventional device, and to perform key input with a feeling similar to the input operation of a keyboard of a normal computer or the like. is there.

[0019]

The present invention provides a main body, a display section provided on the front surface of the main body, a key input section provided on the front surface of the main body around the display section and on the rear surface of the main body, and capable of inputting with a finger. Since it is configured to include, that is, since a key input unit for inputting by pushing with a finger is provided, it is possible to input with a finger, and quick and accurate key input is possible. You can also input with a pen,
It is possible to select both, and it has high convenience.

Further, since the input keys for characters and symbols are provided on the rear surface and the delete key is provided on the front surface, deletion due to an operation error is prevented.

Further, since there is a raised portion protruding from both sides of the main body, and the raised portion is provided in the vicinity of the key input portion or the second key input portion on the front surface of the main body, the raised portion is held by both hands. However, since it is possible to input from the key input section on the front surface of the main body, it is highly portable and its convenience is improved.
