BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyboard device of a portable hybrid computer. In particular, the present invention relates to a keyboard device suitable for use in a hybrid portable computer having a web pad function and a general notebook PC function. It is possible to selectively input text or data only to reduce power consumption, and in the case of using as a web pad, the keyboard device of a portable hybrid computer that can be detached from the keyboard is easy to carry when moving. It is about.

In recent years, with the change of office type, which emphasizes mobility, the transition from the previous desktop PCs to portable notebook PCs or personal digital assistants (aka PDAs) has increased significantly.

1 is a view showing the appearance of a conventional notebook PC.

Referring to FIG. 1, in the case of a conventional notebook PC, a system part of a desktop PC and a keyboard part are integrally configured to form a main body part, and a liquid crystal display is rotatably provided on one side of the integrated main body part. Thus, text or data is input using the integrated keyboard.

However, in the conventional notebook PC, the keyboard device, which is a data input means, is always rotatably fixed to the main body of the system. Since it is not so easy, a sub PC having a separate FDD or CD-Rom drive is used.

2 is a view showing the appearance of a conventional personal information terminal.

Referring to FIG. 2, in a conventional personal information terminal (also known as a PDA), data is input using a stylus pen, which is first implemented as software and taps a virtual keyboard displayed on a screen. Enter data or use a stylus pen on the display to write.

In the former case, it is very inconvenient to use a character by tapping an extremely small virtual keyboard on the screen, and in the latter case, the character is written by a writing operation using a pressure sensitive liquid crystal display. In addition, when a user writes and writes a text, WebPad recognizes it as text, and this writing operation causes many errors (character recognition errors) in text recognition despite the user's flexibility and convenience. In the case of creating a document while carrying, there is a problem in that the writing of the document is not easy because the text input is performed while the web pad is not firmly supported.

Figure 3a, b is a state diagram before and after the web pad is mounted on a conventional removable keyboard device.

Referring to these drawings, a conventional personal digital assistant or a web pad is mounted on a separate removable keyboard device, and a web pad used while being carried while moving is used to input data such as letters using a stylus pen. In this case, the software is implemented by tapping a virtual keyboard displayed on the screen and inputting data or writing using a stylus pen directly on the display. Even if a character is recorded by using a writing operation, it is inherently inconvenient due to many errors occurring in character recognition.

The conventional detachable keyboard device designed to solve such inconvenience is characterized in that the upper end of the keypad 811 is provided with an interface unit 812 for connecting a web pad, etc., wherein the interface unit 812 is a keypad. It is integrally formed with a cover 813 covering the cover, and is rotated with the hinge provided at one end of the cover 813 as a point. In the conventional detachable keyboard device as described above, a web pad or the like is inserted into the interface unit 812 to input data such as characters using the keypad 811.

However, when such a detachable keyboard device is connected to the connector of the keyboard device, such as a web pad, the keyboard is always switched to a mode that can input text, so that the keyboard can input data such as text, power is always applied to the keyboard. Even when no text is inputted, power consumption may occur. In addition, there is a problem in that the use of the web pad is impossible to cover the keyboard cover after mounting the web pad and the like to the keyboard cover.

When the user specifically wants to confirm the contents of his / her work to the counterpart, the counterpart can see the display only when the entire body part is rotated in the direction desired by the user.

A conventional notebook PC having a conventional rotatable display unit 817, which is designed to solve such inconvenience, allows the display unit 817 to be rotatable about a rotation shaft 815 on one side of the main body unit 814. By doing so, the display unit 817 is hinged to the rotating means 816 which is rotated by the motor 818. Therefore, when the user wants to rotate the display unit 817 in a desired direction, the motor rotates the display unit 817 hinged to the rotating means 816 by a forward / reverse rotation by a desired angle. I can do it.

However, the conventional notebook PC having the rotatable display unit merely changes the angle of the screen without realizing a separate additional function according to the rotation, and the display unit is always mounted on the main body so that the main body except the display unit There is a problem that can not be used while carrying alone.

5 is a view showing a state of use of the display unit opening and closing device of the conventional notebook PC.

Referring to FIG. 5, a conventional notebook PC has a system unit and a keyboard unit integrally constituting a main body portion, and the liquid crystal display is opened and closed at one side of the unitary main body portion. The opening / closing button 819 sliding in the left and right sides of the case and the opening / closing button engaging hole 820 formed at opposite positions of the main body so as to catch the protrusion formed on one side of the opening / closing button 819 and the opening / closing button ( A return spring 821 for returning to the original position during the left and right sliding operation of the 819.

However, the display unit opening and closing device has a inconvenience that the user must operate the left / right fingers at the same time because the left and right opening and closing button 819 is not interlocked.

The keyboard device 300 of the present invention devised to solve the above problems is simply attached to the system main body 100 to be used as a web pad, thereby selectively inputting text and data using a keyboard if necessary. Although the keyboard is attached, even when the keyboard is attached, the keyboard is coupled to the system main body 100 in a folded state so that data input through the keyboard is restricted so that only the function of the web pad is enabled, thereby enabling the keyboard. The purpose of the present invention is to realize power saving by eliminating the conventional power consumption of waiting for key input in one state.

In addition, by enabling the coupling direction of the system main body 100 and the keyboard device 300 in both the forward direction and the reverse direction, when the portable device is to be stored / stored for a long time without a key input, the keyboard device 300 of the present invention is carried out by the system main body 100.
