Abstract

PURPOSE: To enable an instructor to easily operate a keyboard and a mouse even at the time of inverting a display panel (cover part) to turn it to the auditor side by improving the efficiency of a word processor, a spreadsheet, generation of a data base or the like, and the editing work. CONSTITUTION: A keyboard 3 is mounted on the upper race or a main body 1, and a cover part 2 is freely openably and closably attached to the main body 1, and a liquid crystal display device 4 is attached to its inside face. The cover part 2 is inverted to turn the liquid crystal display device 4 to the opposite side or the keyboard 3, and in this state, the cover part can be locked in the position opened from the main body. Especially, an auxiliary liquid crystal display device 5 smaller than the liquid crystal display device 4 is attached to the upper face of the main body in this invention.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a personal computer (hereinafter referred to as a personal computer), and more particularly to a personal computer equipped with a liquid crystal display panel that can be opened and closed.

[0002]

2. Description of the Related Art An image which can be displayed on a liquid crystal display of a portable personal computer is 640 vertical by 400 horizontal, which is narrower than 1024 by 768 dots of a high resolution CRT display of a desktop computer. Therefore, it is difficult to display two images on the same screen in terms of resolution. Therefore, creating word processors, spreadsheets, databases, etc.
In editing work, refer to specific sentences, tables, figures, etc. stored in the memory, or when diverting, change the display on the display to the image to be referred or diverted, and then copy, cut, etc. Then, the operation of restoring the display on the display is performed again, and then the procedure of copying and pasting is performed. That is, it is necessary to frequently move and switch the display on the display.

Further, in a portable personal computer in which a display panel can be inverted and attached for presentation,
When inverted, the display panel faces away from the keyboard, and it is difficult to operate with the keyboard, so a mouse is used, but the operator enters the side where the presentation is being listened to and the liquid crystal display is tilted. While viewing from an angle, the operation and explanation are performed while alternately facing the listener and the display.

[0004]

As described above, in the conventional portable personal computer, other sentences, tables, figures, etc. are referred to or diverted in the preparation and editing of word processors, spreadsheets, databases, etc. At that time, the display was repeatedly moved and switched each time, which was very inefficient.

Further, in a portable personal computer in which a display panel can be inverted and attached for presentation,
When inverted, the display panel faces away from the keyboard, and keyboard operation is almost impossible. Even when using the mouse, the instructor (operator) must enter the side that listens to the presentation and look at the liquid crystal display from an oblique angle, and operate the mouse by himself. However, there is a drawback in that the presentation must be carried out in a very burdensome manner while alternately facing the listener and the display in opposite directions, while being positioned on the side of listening to the presentation.

The object of the present invention is to solve these conventional drawbacks and improve the efficiency of word processing, spreadsheet, database creation and editing work, and even when the display panel is turned upside down to the listener side. The instructor (operator) tries to easily operate the keyboard and mouse.

[0007]

In the structure of the portable personal computer having the main body and the lid portion, in the present invention, an auxiliary liquid crystal display smaller than the liquid crystal display is mounted on the upper surface of the housing of the main body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will now be described with reference to the drawings. FIG. 1 is a schematic explanatory diagram when the present invention is applied to a notebook computer. Reference numeral 1 is a main body of a personal computer, and a keyboard 3 is mounted on the upper surface of a housing 1a. Reference numeral 2 denotes a lid portion which is attached to the main body 1 so as to be openable and closable and reversible
The liquid crystal display 4 is attached to the inner surface thereof. In the present invention, an auxiliary liquid crystal display 5 smaller than the liquid crystal display 4 is mounted on the upper surface of the housing 1a of the main body.

When creating or editing a word processor, spreadsheet, database, etc., when referring to or diverting specific sentences, tables, figures, etc. stored in the memory, those images are displayed on the auxiliary liquid crystal display 5. Since it can be displayed, it is extremely convenient and can greatly improve work efficiency. FIG. 1B is a diagram showing the state where the lid portion 2 is inverted and attached in order to use the personal computer for a presentation. In this case, the instructor can display the same image on the auxiliary liquid crystal display 5 and, while watching it, operate the keyboard and mouse and explain the presentation from the keyboard side in a comfortable posture facing the listener. it can.

FIG. 2 is a block diagram showing the electrical construction of the personal computer shown in FIG. A CPU (central processing unit) 7, a ROM 8, a RAM 9 and an input / output interface unit 10 are connected via a bus 6, and the input / output interface unit 1
0 to keyboard 3, liquid crystal display 4 and auxiliary liquid crystal display 5
Is connected.

[0011]

As described above, according to the present invention, a small auxiliary liquid crystal display 5 is provided near the keyboard 3 of the portable personal computer body 1 in addition to the normal liquid crystal display 4 to provide a word processor and a display. By displaying specific sentences, tables, figures, etc. to be referenced or diverted on the auxiliary display device 5 in the calculation, creation of a database, etc. and editing work, the above-mentioned work can be efficiently performed.

Further, when the lid portion 2 is attached upside down for a presentation, the display 4 faces the side opposite to the keyboard 3, but the same contents as those of the normal display 4 are displayed on the auxiliary display. By displaying in 5, the instructor can operate the keyboard or mouse and explain the presentation in a comfortable posture while facing the listener.

[Brief description of drawings]

FIG. 1 is a perspective view showing an embodiment in which the present invention is applied to a notebook type personal computer, in which A shows a use state in which a lid is opened and locked, and B shows the personal computer for use in a presentation. , Shows the case where the lid is reversely attached.

FIG. 2 is an electrical block diagram of the embodiment shown in FIG.
