ABSTRACT:
In a keyboard including a plurality of keys, each key has a key top, a guiding structure that includes linking units pivotally movable in response to vertical motion of the key top, an elastic member to be pressed down by the vertical motion of the key top, and a contact which is operatively associated with the vertical motion of the key top. The guiding structure includes a common unit which is shared with all the other keys.
