1. Field of the Invention
The present invention relates to a keyboard and in particular to a touchpad keyboard structure.
2. Description of Prior Art
A keyboard is one of the indispensable peripheral accessories for a desktop computer or a notebook computer. It is used to input operating commands to execute a specific function by a user.
Except a touchpad (control cursor motions) on a keyboard used in a desktop computer or a notebook computer, other function keys, typing key group, and hot keys are designed with mechanical-pressing structures. For example, a typing key has a keycap. After the keycap is pressed, the structure inside the keycap will press a rubber elastic layer to press a film type PCB or a hard PCB to generate operation signals to input to a computer host.
Manufacturing the keyboard with the touchpad (control cursor motions), the function keys, the typing key group, and the hot keys is inconvenience because the manufacturing process of the touchpad is separated from the function keys, the typing key group, and the hot keys.
Moreover, the function keys, the typing key group, and the hot keys on the keyboard are mechanism design. When the keycaps are pressed by a user's fingers, it will easily result noise. Moreover, when the keycaps are pressed by a user's fingers, the press force will cause the structures of the pressed keys damage, so that the pressed keys can't be pressed to generate operation signals. It's inconvenience for the user when using.
