  • Patent number: 8104979
    Abstract: A keyboard includes a first housing having a plurality of first magnetic elements, a keystroke module having a key portion disposed on the first housing, a second housing combining with the first housing and has an opening, and an actuating assembly. The keystroke module is disposed corresponding to the opening. The actuating assembly is disposed movably on the second housing and has a plurality of second magnetic elements. The keystroke module is not protruded from the opening and is at a packing position. When the actuating assembly is moved along an actuating direction, at least one first magnetic element and at least one second magnetic element attract to each other to shorten the distance, which brings the second housing to move relatively to the first housing so that the key portion of the keystroke module passes though the opening and is at a using position.
