Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable information processing device, and more particularly to a lightweight, compact and highly operable portable information processing device.

[0002]

2. Description of the Related Art Conventionally, there are several types of portable information processing devices of this type, such as a notebook personal computer, a pen personal computer and a handy terminal.

The notebook type personal computer is used for the purpose of carrying the function of the desktop type personal computer even if it is portable. Pen personal computers have been used for the purpose of operating with a pen to make the personal computer more compact and to eliminate key input. Further, the handy terminal is used for the purpose of holding the apparatus main body with one hand and inputting data with the other hand.

[0004]

In the above-mentioned conventional notebook type personal computer, it is always necessary to put both hands on the upper part of the keyboard to operate, so that the place is limited and the use place cannot be arbitrarily selected. There is a point. Further, when a pen personal computer is used, there is a problem that it is not suitable for processing a large amount of data because of lack of speed and operability because the data is input by the pen. Furthermore, when using a handy terminal, the device is held by one hand and the key is operated by the other hand, so there is a problem that it is not suitable for operation with both hands to further increase the speed. .

The object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide a portable information processing device that eliminates restrictions on the place of use and increases the speed of operation.

As described above, according to the present invention, the front and back keys are arranged so that the keys can be operated not only on the front surface but also on the back surface of the keyboard integrated with the main body of the apparatus. The number of keys can be reduced and the space required for the keyboard can be saved by arranging eight keys corresponding to eight fingers other than the thumb so that the device can be operated by holding it against the palm and preventing the device from falling. There is an effect that the restriction of the place of use can be greatly improved while improving the property. Further, by limiting the thumb to the front surface operation only and the other fingers to the back surface operation only, the front and back surfaces can be simultaneously operated by both hands, which has an effect that the device can be operated quickly. Furthermore, since the strokes are extended in the pressing direction of the eight backside keys to change the key input, the operability of entering letters, numbers and symbols with a small number of keys and a single key on the menu screen There is an effect that the promptness of the input operation for selecting a plurality of characters can be significantly improved.
