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.

Abstract: A keyboard with elevated keys for a notebook computer. The keys of the keyboard are elevated when the notebook computer is opened, and can be depressed when the flat display is closed. The keyboard has keys movably connected to the foundation sheet through scissors-type linking mechanisms. A plurality of guiding sheets is movably disposed on a foundation sheet and has hooks and tracks. Each of the tracks is parallel to a first direction. A sliding member is movably disposed on the foundation sheet and has protrusions extending into each of the tracks. When the sliding member moves in the first direction, the protrusions move the guiding sheets from a first position to a second position. The hooks of the guiding sheets sequentially press the scissors-type linking mechanism of each key to depress the keys of the keyboard from elevated position to depressed position.

Abstract: An elevated and lower and lower keyboard apparatus comprises a base, plural of key-top-lids, plural of scissors-devices and a guiding board. The scissors-device comprises a first connection rod and a second connection rod, which are intersected to form a turning scissors configuration, which is arranged between the base and the key-top-lid. Through the confinement of the scissors-device, the key-top-lid may make a rise-up and lower-down motion relatively to the base. In a movable manner, the guiding board is arranged on the base to process a movement between a first position and a second position. Relative to the plural of scissors-devices, there are plural of guiding blocks formed on the guiding board. When the guiding board moves from the second position to the first position, the guiding block presses upon the second connection rod and makes the second connection rod move closely to the base, and further, relatively to the base, it makes key-top-lid lowering down. When the guiding block moves from the first position to the second position, through an elastic body, it can rise up the key top-lid relatively to the base.

Abstract: A keycap support mechanism increases the stability of supporting a keycap through structure designs of supports. Two supports are pivotally connected around a pivot axis. One of the supports includes a support body and a reinforcement part embedded into the support body. The elastic modulus of the reinforcement part is greater than the elastic modulus of the support body. In an embodiment, the reinforced support includes Z-shaped bending structure extending parallel to the pivotal axis. In another embodiment, the reinforced support has a sliding shaft and a sliding hole formed beside the sliding shaft. The reinforced support is slidably and rotatably connected to the keycap through the sliding shaft. The reinforcement part surrounds the sliding hole and goes through the sliding shaft. A keyswitch structure includes a base plate, a keycap, and any of the above keycap support mechanisms. The keycap support mechanism supports the keycap above the base plate.
