Description

KEYBOARD FOR HAVING PORTABLE COMPUTER BUILT-IN

The present invention relates to a keyboard as a computer input device and more particularly to a portable computer (for example, a tablet PC or the like) that executes a program using a touch screen method as a main input method by simply operating a keyboard, The portable computer is housed and stored in the portable computer when the portable computer is portable, and the portable computer is taken out and used when the portable computer is used. Thus, the portable computer can be stored in a portable computer Gt;

Recently, portable computer market is dominating the mainstream desktop computer market as the low - power design and high performance performance technology of computer hardware are remarkably developed. One of the portable computers, a tablet PC, is a touch-screen type in which a character is recognized by touching the LCD (Liquid Crystal Display) screen directly using a finger or an electronic pen without a separate keyboard. Is a mobile Internet device that combines the portability of a PDA (Personal Digital Assistant) and the functionality of a notebook.

This tablet PC has a built-in touch screen and can run a program using a finger or an electronic pen. It is a new mobile computer with a new platform that enables internet access from anywhere via a wireless LAN. The main input device is a touch screen, You can connect a keyboard or mouse and use it to expand the input method.

However, when the keyboard is connected and the input method of the tablet PC is expanded, the user has to carry the keyboard at all times apart from the tablet PC, which is an obstacle to the portability of the tablet PC. As a result, The input method is limited to use in a limited space, and its use is extremely limited.

In order to solve this problem, Korean Utility Model No. 20-2008-0006600 (published on December 30, 2008) proposed "a structure in which a keyboard of a portable computer is mounted in the body in the form of a slide loading" Patent No. 10-2005-0123292 (published on December 29, 2005) proposes an "Auto PC with a draw-out type folding keyboard ".

Korean Utility Model Publication No. 20-2008-0006600 discloses a structure in which a keyboard is mounted inside a main body in the form of a slide loading (a structure in which the keyboard is slid into the main body and mounted on the main body) It is possible to position the display portion on the surface while moving away from the structure, thereby enhancing the beautiful design and portability.

Korean Patent Laid-Open Publication No. 10-2005-0123292 discloses a keyboard having a keyboard receiving portion, a first keyboard having a width that can be drawn out through the keyboard receiving portion, and a second keyboard A rack gear connected to a lower end of the first keyboard and a pinion gear configured to move the rack gear forward and backward by rotation of the rack gear, 1 keyboard and the second keyboard so that the keyboard can be easily inserted into and withdrawn from the bottom of the Auto PC.

However, in the structure proposed in the prior arts including the above-mentioned prior arts, the keyboard is mostly housed in the main body. In order to accommodate the keyboard therein, the structure of the existing computer main body must be changed, Not only can not be applied to a portable computer such as a tablet PC, but also requires a separate computer body, resulting in a great economic loss.
