DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desktop liquid crystal display computer (hereinafter referred to as a desktop LCD computer), and more particularly to a portable desktop LCD computer.

[0002]

2. Description of the Related Art As shown in FIG. 20, a conventional desktop computer comprises a main body 12, a display (CRT or LCD) 1
0, a keyboard 16, a mouse 18, a speaker 20, and other accessory equipment. Since the accessory equipment of the desktop computer is separated into independent units, there are the following drawbacks in use.

[0003] 1. Since all the necessary accessories for the computer are separated into independent units, in order to use all the accessories at the time of use, there must be enough space for each, and if the main computer and all Even though the accessories can be put together, the desk on which the computer is mounted looks very small because it takes up a lot of space on the desk.

[0004] 2. Because the display of the desktop computer and the main engine and other auxiliary equipment are all independent individuals,
If you move to a different location, including the entire desktop computer and its accessories, you will have to spend a lot of time and effort carrying them. Therefore, while desktop computers are being researched and developed to be lighter and thinner, lighter and thinner desktop computers do not necessarily require the same "portability" as ordinary notebook computers. The present invention utilizes a concept of a liquid crystal display of a notebook computer, and develops a computer having a relatively small volume and a mobility that is easier than a general desktop computer by combining with an additional device such as a keyboard. Is what you do.

[0005]

That is, in view of the above-mentioned problems of the conventional desk-top type computer, the present invention has an effect that the occupied space can be reduced and portable by integrating the accessory equipment of the computer. It is another object of the present invention to provide a desktop LCD computer capable of protecting a display with a lid.

[0006]

Pivotally attached to the lower edge of the housing, and can rotate between a first position and a second position. When rotated to the first position, the housing is orthogonal to the housing and moved to the second position. When turned, it folds parallel to the housing
It comprises a lower lid that covers the LCD panel from the front, and a keyboard attached to the lower lid and capable of keying data when the lower lid is in the first position.

[0007] Further, by adding various appropriate members, for example, the lower lid is formed to have a width that covers substantially the lower half of the front of the LCD panel and a width that covers the upper half of the front of the LCD panel. An upper lid is provided so as to be rotatable upward and detachable upward, or a leg is provided at the bottom of the housing, and an upper end surface portion having an upward opening in the leg seat, and an appropriate interval provided on the upper end surface portion are supported. A receiving plate, a bearing adapted to support a table-top LCD computer, and a localization device for restricting movement of the bearing relative to the leg, so that the bearing is movable between the two supporting plates. To allow the display to move from the first state in which the display is facing down to the leg, to the second state in which the display is turned up, and if the bearing moves to the first state. Presents a substantially upright state of the display computer, if moved to the second state or to assume an inclined state where the computer display is Aomui, since elaborately various ingenuity and the like are preferable.

According to the present invention, the LCD panel, the main circuit board and the speaker are integrally provided in the housing, the keyboard can be folded and stored inside the lower lid, and the mouse and other electric connection cords can be stored. The upper lid and the lower lid do not take up much space on the desktop, and if the desktop LCD computer and other additional equipment are to be moved and installed elsewhere, the upper lid and lower lid should be LCD with the handle provided
You can easily carry your computer. Also, LCD
When the computer is not used, the upper and lower lids can protect the LCD panel. If the keyboard is removed from the housing and the data input to the keyboard is transmitted by the infrared transmission method, the keyboard can be placed in a comfortable place and at an angle, and the user can use the computer comfortably. The upper lid can shield the LCD panel if necessary.
