  • Publication number: 20100006412
    Abstract: A keycap and a press key structure along with a keyboard using the same are disclosed. The keycap, being comprised of a top and a bottom having a concave-convex structure formed thereon, is structured for allowing light to pass therethrough. There is a connecting component sandwiched between the keycap and a substrate in a manner that it is pivotally connected to the two in respective for allowing the keycap to move up and down in relative to the substrate. Moreover, there is at least a light source being disposed between the keycap and the substrate for projecting light to the concave-convex structure on the keycap? bottom and out of the keycap through the top thereof after being uniformly scattered by the concave-convex structure. Thus a press key is constructed. It is noted that by arranging a plurality of the aforesaid press keys in an array, a keyboard is constructed.

  • Publication number: 20090038923
    Abstract: A keyboard includes a keycap, a pivot structure, a base and an X-structure. The keycap includes a bottom surface, a first edge and a second edge. The pivot structure includes two first engaging portions and two second engaging portions. The first engaging portions are disposed on the bottom surface and have a first distance away from the first edge. The second engaging portions are respectively disposed corresponding to the first engaging portions and have a second distance away from the second edge. The base is disposed under the keycap. One end of the X-structure is connected to the pivot structure of the keycap and the other end of the X-structure is movably connected to the base, thus, the keycap moves upward and downward corresponding to the base.
