Abstract
A keyboard is disclosed and includes a base plate, a plurality of key structures, a plurality of switches, and a capacitive touch sensing device. Each of the key structures is disposed above the bottom plate and includes a keycap capable of moving up and down relative to the base plate. Each of the switches corresponds to one of the keycaps and is disposed under the corresponding keycap. Each of the keycaps is capable of moving toward the base plate to trigger the corresponding switch. The capacitive touch sensing device is disposed under the key structures, for sensing a touch operation performed on the keycaps. The functionality of the keyboard of the invention therefore improves. The keyboard uses an identical projection area to perform keying and touch operation, which avoids the inconvenience for a user when using both a keyboard and a touchpad in the prior art.
