Abstract

The invention provides a portable computer and a keystroke device, in particular to a device and a method of performing keystroke by using the change of electrostatic capacity. The key device of the portable computer is characterized in that the keystroke device comprises a plurality of electrostatic capacity units sensing the electrostatic capacity, a signal checkout unit and a signal transmission unit. The electrostatic capacity units are arranged on the lower part of a main frame. The signal checkout unit checkouts the sensing signals of the electrostatic capacity unit in the form of a keying signal. And the signal transmission unit transmits the checkout sensing signals to a system according to the signal checkout unit.

Description

technical field [0001] The invention relates to a portable computer and a key input device thereof, in particular to a device and a method for key input using changes in electrostatic capacity. Background technique [0002] Generally, a portable computer (so-called notebook computer) is equipped with a mouse (Mouse) and a touch panel (Touch Pad) for inputting point data. Such devices are also known as so-called point-and-click input devices. Therefore, the user can easily input point-and-click data on the screen through the point-and-click input device. [0003] figure 1 It is a schematic diagram of a portable computer with a touchpad. [0004] refer to figure 1 , which is composed of an LCD panel 6, a keyboard 8 provided on the host computer, and a touch panel 2 provided on one side of the keyboard 8 of the host computer. [0005] For example, the above-mentioned keyboard 8 inputs commands or data specified by the notebook computer in the form of ASCII values. Also, t...
