Patent ID: 7532466

Claim:
An extension unit for an electronic apparatus, comprising: an enclosure defining a surface receiving the electronic apparatus; a connector placed in the surface of the enclosure for connection to the electronic apparatus; an operating body coupled to the enclosure for relative movement between a retract position and a pulled-out position, the operating body retracting inside the enclosure when the operating body is set at the retract position, the operating body pulled out of the enclosure when the operating body is set at the pulled-out position; and an interlocking mechanism enabling withdrawal of a lifting member into the enclosure when the operating body is set at the retract position, the interlocking mechanism enabling protrusion of the lifting member out of the surface of the enclosure to urge the electronic apparatus upward based on movement of the operating body from the retract position toward the pulled-out position, wherein the interlocking mechanism allows movement of the operating body from the pulled-out position to the retract position while keeping the lifting member protruding out of the surface of the enclosure.
