Abstract

PROBLEM TO BE SOLVED: To enable not only an operator who operates a keyboard, but also a 3rd party around the operator to easily see information displayed on a display by providing liquid crystal display panels which display an image of inputted information on the front surface and back surface of a display unit. SOLUTION: To use a personal computer for a conference or previous arrangement, the display unit 2 is raised to expose one liquid crystal display panel 6 as the 1st display screen on its front side and also expose the other liquid crystal display panel 7 as the 2nd display screen by opening a protection cover 10. In this state, the operator of the personal computer operates keys 5 of a keyboard unit 1 to input specific information. In response to the input, an image of the information is displayed on the front-side liquid crystal display panel 6 and rear-side liquid crystal panel 7 of the display unit 2 respectively. Therefore, even the 3rd party who is before or around the operator can easily see data, figures, etc., displayed as the operation is done at any time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable information processing apparatus such as a personal computer or a word processor which inputs predetermined information via a keyboard and sequentially displays images of the input information on a display.

[0002]

2. Description of the Related Art In recent years, so-called notebook type personal computers and sub-notebook type personal computers have become widespread as OA equipment for processing information such as various data. Then, bring this personal computer to various conferences and meetings, and one of the occupants operates the keyboard to display various data and figures on the display, and the displayed data and figures are displayed at other banquet halls. It is usual to hold meetings and meetings while presenting them to the people.

[0003]

However, the display in the conventional personal computer or word processor has a structure that is easy to see only for the operator who operates the keyboard.
Therefore, as described above, one operator operates the keyboard at the conference or meeting seat to display data or figures on the display and show the display to a third party to proceed with the meeting or meeting. In that case, it is very inconvenient if the computer or word processor is turned to the seat of a third party each time it is shown, or the third person himself leans beside the operator and peeks at the deathplay. Is inefficient.

The present invention has been made by paying attention to such a point, and the purpose thereof is not limited to the operator who operates the keyboard, but also a third party arranged in front of or around the keyboard is displayed on the display. An object of the present invention is to provide a convenient portable information processing device capable of easily and sequentially viewing information such as generated data and graphics.

[0005]

In order to achieve such an object, the present invention provides an invention according to claim 1 in which a display unit is provided on a keyboard unit for inputting information so that the display unit can be moved up and down. A liquid crystal display panel for displaying an image of information input through the keyboard unit is provided on each of a front surface and a rear surface of the unit, and the invention can be moved up and down on the keyboard unit for information input. A display unit is provided on the top of the display unit.
A liquid crystal display panel that rotatably mounts a display board facing the back surface of the display unit, and displays an image of information input via the keyboard unit on the front surface of the display unit and the front surface of the display board. According to the invention of claim 3, a display unit is provided on a keyboard unit for inputting information so as to be capable of undulating, and a display board is rotatable on at least one side edge of the display unit. A liquid crystal display panel for displaying an image of information input via the keyboard unit is provided on the front surface of the display unit and the surface of the display board.
