Abstract: A bendable support device is provided, which includes a support plate, a slidable plate and a pivot mechanism. The support plate has a first portion and a second portion laterally adjacent to the first portion. The slidable plate is disposed over the first portion of the support plate. The pivot mechanism is pivotally connected between the first portion and the second portion. The slidable plate is configured to move toward the pivot mechanism when an angle between a lower surface of the first portion and a lower surface of the second portion is changed from 180 degrees to less than 180 degrees.

Abstract: A keyboard device includes a base plate, a plurality of key structures, a floating frame and a cover layer. The key structures are disposed over the base plate, and each of the key structures has a keycap. The floating frame is disposed over and separated from the base plate. The floating frame has a plurality of openings, and the key structures are disposed in the openings, respectively. The cover layer covers the keycaps of the key structures and the floating frame and is in direct or indirect contact with an upper surface of the keycap of each of the key structures and an upper surface of the floating frame. When the keycap of one of the key structures and the cover layer thereover are pressed to bottom, the floating frame surrounding the one of the key structures is pulled by the cover layer and shifted.

Abstract: A luminous touch pad includes a covering plate, a circuit board, a light guide structure and a first light-shading adhesive. The covering plate includes a first surface and a second surface. The circuit board is located under the covering plate. The circuit board includes a third surface and a fourth surface. The light guide structure is arranged between the covering plate and the circuit board. The light guide structure includes a lateral surrounding surface. An adhesive receiving space is defined by the lateral surrounding surface, a portion of the second surface and a portion of the third surface collaboratively. The first light-shading adhesive is disposed within the adhesive receiving space and arranged around the light guide structure. The first light-shading adhesive is contacted with the portion of the second surface, the portion of the third surface and the lateral surrounding surface.
