Electronic device

An electronic device comprising:

• a keyboard having a support plate, wherein said support plate includes a top face and a bottom face;
• a support having a top face and connected to said bottom face of said support plate, wherein said support is allowed to move between a lower position where said support moves down due to a biasing force from an elastic member and an upper position where said support moves up against said biasing force from said elastic member;
• a manipulating member supported on said top face of said support, wherein said manipulating member is exposed on a surface of said keyboard through an opening of said support plate;
• and
• a driving member movable relative to said support plate in a direction parallel to said top face of said support plate, wherein said driving member includes a limiter for holding said support at said upper position to limit movement of said support to said lower position, and when said support is at said upper position and said driving member and said support plate move relatively, wherein said limiter releases said support so that said support moves from said upper position to said lower position, and said manipulating member moves downward in said opening.
