Abstract
A keyboard includes a base plate, plural keycaps, plural scissors-type connecting elements and a sliding plate. Each scissors-type connecting element has a bulge. The gliding plate has plural position-limiting structures. The keyboard is installed on a notebook computer and connected with a top cover of the notebook computer. For operating the keyboard, the bulge is received in a first step part of the position-limiting structure. Consequently, the keycap is at a higher height. Since the keycap is at a higher height, the movable distance of the keycap is large enough to provide better tactile feel. For storing the keyboard, the bulge of the scissors-type connecting element is moved to the second step part of the position-limiting structure. Consequently, the height of the keycap is reduced, and the keyboard has a slim appearance.
