Patent ID: 8023038

Claim:
A camera module, comprising: at least one lens; a barrel receiving the at least one lens therein; an image sensor aligned with the at least one lens; a carrier carrying the image sensor thereon, the carrier having a comb-shaped first electrode having a plurality of first teeth; two spring supporting members each having a first anchor and a second anchor, the first anchors thereof being attached to opposite sides of the carrier; a frame receiving the carrier and the two spring supporting members therein, the second anchors of the two spring supporting members being secured to the frame in a manner such that the carrier is suspended in the frame and is movable in a direction perpendicular to a sensing surface of the image sensor; a base having a through hole therein, and a comb-shaped second electrode having a plurality of second teeth extending inwardly in the through hole, the base supporting the frame, the first teeth being disposed above the second teeth, the first teeth and the second teeth arranged in a staggered fashion; and a printed circuit board for providing a potential difference between the first electrode and the second electrode, whereby an electrostatic force is generated between the first teeth and the second teeth to drive the first teeth to move towards the second teeth.
