Description

external input device

technical field

The utility model relates to an input device, in particular to an external input device.

Background technique

Traditionally, the input device used as the man-machine interface is a keyboard and a mouse or a touch panel.

The existing keyboard has character keys, number keys and multiple function keys, and the user can use the keyboard to input characters, numbers and execute various built-in functions of the computer. However, although the function keys of the keyboard can be used to move the cursor on the computer screen, the disadvantage of using the existing keyboard to move the cursor is that the cursor can only move the cursor in the window in use, but cannot move the cursor outside the window. toolbar to allow the computer system to perform other functions. Therefore, when the user wants to input to the computer system, he needs to use the mouse or the touch pad together.

The existing mouse has a left button and a right button, and can also have a middle button. The user can use the mouse to move the cursor on the computer screen quickly, to click, to open the tool bar and to scroll the window. However, since the user needs to use the keyboard and the mouse at the same time when he wants to input to the computer system, the disadvantage of using the existing mouse is that when the user wants to use the keyboard or the mouse to perform different functions of the computer system, they must use them alternately.

Notebook computers use a touchpad as a mouse, so the touchpad not only has the above-mentioned functions of the existing mouse, but the user can further input directly on the touchpad by writing. However, the disadvantage of using the existing touchpad is that when the user wants to use the keyboard or the touchpad to perform different functions of the computer system, especially when inputting numbers, he must use both hands to use them alternately. For example: first use the text keys on the keyboard to input text, then use the number keys on the keyboard to input numbers, and you must use the touchpad to move the cursor. If you want to use the mouse function to position the cursor or perform digital input in the middle of text input, you must switch before you can achieve it, causing trouble and inconvenience for the user to use the keyboard, mouse or touch panel.

At the same time, the touch panel used in the existing notebook computer is made by laminating the printed circuit board with an adhesive film. Due to problems such as gaps, impurities or air bubbles between the adhesive film and the printed circuit board, resulting in poor induction or poor recognition, resulting in abnormal function of the touch panel.
