BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a portable personal computer equipped with a liquid crystal screen. Recently, as portable devices such as personal computers and word processors (hereinafter referred to as portable computers) have become widely used to improve work efficiency,
There is a need for portable personal computers that are easy to carry and operate. However, the projection dimensions of current portable computers are limited by the size of the main body's keyboard, and the lid, which has an LCD screen on the front side and is hinged to the main body so that it can be opened and closed, is thick for strength. Therefore, there is a need for a new portable computer structure that can be made even thinner and prevent the LCD screen from being destroyed during use, as well as a structure that can be folded to reduce the projected size and protect the keyboard and LCD screen when carried. .

0002

BACKGROUND OF THE INVENTION The structure of a conventionally widely used portable personal computer is as shown in FIG. LCD screen 3-1 is attached to the hinge part 1-1 of
A convex hinge part 3-2 formed on the opening/closing center side of the lid 3 fixed so that it faces the front is fitted, and a rotation axis is connected to the concave hinge part 1-1 and the convex hinge part 3-2. 4, the lid 3 is hinged to the main body 1 so that it can be opened and closed at a fixed angle.

[0003] When the lid 3 is opened and tilted forward, the liquid crystal screen 3-1 becomes tilted at a certain angle, and when the lid 3 is closed, the keyboard 2 of the main body 1 is covered with the lid 3, as shown in FIG. 14(b). It is configured as follows.

0004

[Problem to be Solved by the Invention] The problem with the structure of the conventional portable personal computer described above is as shown in FIG. 14(a).
As shown in the figure, there is a limit to how the key tops arranged on the operation surface of the main body 1 can be made smaller for operational purposes, so it is impossible to make them smaller than A4 size. Since it cannot be made smaller, a problem has arisen in that it is inconvenient to carry.

[0005] Also, the lid 3 is fixed so that the liquid crystal screen 3-1 faces the front, and the printed board unit has electronic components miniaturized, highly integrated, and mounted on printed circuit boards with high density and surface mounting. The built-in main body 1 makes it easy to make the portable computer thinner; however, as shown in FIG.
If the LCD screen 3-1 is held upright at a certain angle of inclination, the LCD screen 3-1 will be damaged due to the bending of the lid 3. To prevent this, the lid 3 must be thick to a certain extent, and the LCD screen 3-1 will be damaged. Since -1 is large, a large force may be applied to the rotating shaft 4 due to the principle of leverage, so the rotating shaft 4 must have a certain diameter, making it impossible to make the main body 1 and lid 3, that is, the portable computer, thinner. is occurring.

[0006] In view of the above-mentioned problems, the present invention has a structure that reduces the projected size when carried, protects the keyboard and LCD screen, and can be folded for convenient carrying, and a lid and a main body, respectively. The purpose of the present invention is to provide a structure for a portable personal computer that can be made thin and prevent the liquid crystal screen from being destroyed during use.

[0007]

[Means for Solving the Problems] The present invention is based on FIG. 1(a).
As shown in the figure, a dividing line 12a is set in the front-rear direction at the center of the keyboard 2, and the right main body 11-1 and the left main body 11-2 are divided by the dividing line 12a to form a pair.
Key tops 2a of the divided keyboards 12-1 and 12-2 as shown in FIG.
A foldable hinge mechanism 14 is provided such that the two sides face each other, and the lid 13, which has the bifold size liquid crystal screen 13-1 fixed to the front side, is hinged to one of the left main bodies 11-2, and the other side is hinged. The lid 13 is attached to the back side of the right side main body 11-1.
The liquid crystal screen 13-1 is configured to abut against the liquid crystal screen 13-1.

[0008]

[Operation] In the present invention, as shown in FIG. 1(a), the hinge mechanism 14 provided at both ends of the dividing line 12a set in the center of the keyboard 2 separates the right main body 11-1 and the left main body 11-2. By folding the upper surfaces so that they face each other, the right keyboard 12-1 and the left keyboard 1 disposed on the right main body 11-1 and the left main body 11-2, respectively, can be opened.
The key top 2a of 2-2 is on the inside for protection, and the main body has a bifold size, and the LCD screen 13-1
By folding the lid 13 fixed to the front side toward you and bringing the LCD screen 13-1 into contact with the back surface of the right main body 11-1, the LCD screen 13-1 is protected and miniaturized for convenient portability. It becomes possible to measure.
