Abstract
The present invention relates to a portable computer having a foldable keyboard, wherein a sensing means, for example, a pressure sensor serving as a keyboard key is provided on a top surface of a flexible circuit board on which a metal pattern is formed, So that the keyboard of the portable computer can be made thinner by reducing the weight by allowing the keyboard to be folded or folded.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a portable computer, and more particularly to a portable computer having a foldable keyboard for folding a keyboard of a computer.
Generally, in the information age and multimedia age, computers are widely used in general households and offices, and their use is rapidly increasing.
The computer includes a main body, an input device such as a keyboard or a mouse, and an output device such as a monitor and a printer.
Among them, a keyboard is a typical input device for generating electrical signals so that the computer recognizes computer commands for writing documents and for operating other computers.
1 is a perspective view showing a structure of a portable computer according to a conventional technique.
The portable computer is mainly divided into two parts. The portable computer is connected to a main body 30 having a keyboard 32 as a peripheral device such as various central processing units, a hard disk, and the like, a track ball 31, And a display unit 20 having an LCD panel 21.
The keyboard operation of the conventional portable computer configured as described above will be described below.
First, the display unit 20 is raised from the upper surface of the main body 30 of the portable computer to maintain a predetermined angle, and the power switch (not shown) of the main body 30 is turned on. The input data is then output to the LCD panel 20 of the display unit 20 by inputting desired input data using an input device such as a keyboard 32 or a trackball 31 of the main body 30. [
However, ordinary users who are familiar with the keyboard of a desktop computer have difficulty in changing the typing habits of the keyboard or typing the keyboard of the keyboard by using the keyboard of the miniaturized portable computer because the size of the keyboard itself is reduced. There was a problem of inefficiency.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a portable computer having a foldable keyboard in order to satisfy trends of a computer or a portable terminal which can keep the habit of users using a keyboard of a desktop computer intact.
1 shows a structure of a portable computer according to the prior art.
Fig. 2 is a structure of a portable computer according to the present invention; Fig.
DESCRIPTION OF THE REFERENCE NUMERALS
40, 30: main body 20: display portion 13:
21: LCD panel 10,32: Keyboard 12: Second keyboard part
41, 31: Trackball 14: Pressure sensor 11: First keyboard part
15: Flexible Circuit Board
16: Mold frame
In order to achieve the above object, the present invention provides a flexible flexible circuit board on which a conductive metal pattern is formed, sensors provided on the flexible circuit board, and a predetermined region on both sides of the flexible circuit board is folded.
Hereinafter, the structure of a portable computer according to the present invention will be described in detail with reference to FIG.
FIG. 2A is a perspective view showing a structure of a portable computer according to the present invention, and FIG. 2B is a sectional view showing the keyboard of FIG. 2A.
The portable computer is roughly divided into a main body 40 and a display portion 20 in two parts.
The keyboard 10 provided on the main body 40 includes a first keyboard portion 11 fixed to three main portions of the main body and a second keyboard portion 12 electrically connected to both sides of the first keyboard portion 11, ). Preferably, the size of the second keyboard unit 12 is half the size of the first keyboard unit 11. [
The first keyboard unit 11 is provided with sensing means such as a pressure sensor 14 on the upper surface of a substrate member having a metal pattern formed thereon, for example, a flexible circuit board 15, And the upper surface of the flexible circuit board 15 including the pressure sensor 14 is covered with the protective film 13 and the flexible circuit board 15 except for the portion where the pressure sensor 14 is provided is covered with the external pressure A mold frame 16 is formed for protecting the mold frame 16 from being exposed.
The second keyboard unit 12 is the same as the first keyboard unit 11. The second keyboard unit 12 is connected to the flexible circuit board 15 of the first keyboard unit 11 and the flexible circuit board 15 of the second keyboard unit 12 15 are electrically connected to each other and the connecting portion of the first and second keyboard units 11 and 12 is maintained at a predetermined distance and can be folded through the flexible circuit board.
The mold frame 16 at the edge of the keyboard 10 formed by the first keyboard unit 11 and the second keyboard unit 12 protrudes slightly higher than the protective film 13.
Hereinafter, the operation of the keyboard of the portable computer of the present invention will be described.
First, the display portion 20 is raised from the upper surface of the main body 40 of the portable computer to maintain a predetermined angle, and the power switch (not shown) of the main body 40 is turned on. When a predetermined pressure is applied to the pressure sensor 14, the input data is displayed by the key code value corresponding to the pressure sensor 14, Is displayed on the LCD panel 21 of the display unit 20.
The flexible circuit board 15 connected to one end of the first keyboard part 11 and one end of the second keyboard part 12 is folded to connect the second keyboard part 12 to the second keyboard part 12, And is positioned above the first keyboard unit 11. [ At this time, the mold frame 16 at the rim portion protrudes slightly higher than the protective film 15, and a step is formed with the protective film 15, so that the sensor of the first keyboard unit 11 and the sensor of the second keyboard unit 12 Do not touch.
In order to prevent the second keyboard portion from tilting in the downward direction due to the spaced distance between the first keyboard portion and the second keyboard portion when the keyboard is unfolded, in order to prevent the second keyboard portion from tilting in the downward direction, The mold frame portion located at a lower portion of the flexible circuit board may be formed by protruding the first and second keyboard portions at a distance spaced apart from each other.
As described above, since the keyboard of the present invention is installed on a foldable flexible circuit board as a key of a keyboard, it is possible to reduce the weight of the keyboard by making it thinner and the area of the keyboard is larger than that of a conventional portable computer The size of the key itself can be increased, so that the users who use the keyboard of the desktop computer can improve the efficiency of the operation by reducing the inconvenience of the typing due to the change of the size of the keyboard key when using the keyboard of the portable computer.
