发明名称 Keyboard device having plurality of keyswitches
摘要 A keyboard device includes a plurality of keyswitches each having a keytop movable up and down, wherein the angle of the keytop varies depending on whether the keytop is in an initial position or in a pressed position. In this structure, the keytop moves in a direction corresponding to the motion of an operator's finger and thus smooth operations can be achieved, as opposed to a conventional keyboard device in which a keytop moves vertically while maintaining itself horizontal and thus the motion of the keytop occurs in a direction different from the motion of an operator's finger.
