Patent ID: 7800651

Claim:
An image-stabilization driving device for driving an image sensor to move in a plane relative to a substrate, the image-stabilization driving device comprising: a first sliding member connected to an image sensor, the first sliding member having a first elastic holding portion at bottom thereof and an elastic sheet; a first piezoelectrical element having first holding surfaces to be elastically held by the first elastic holding portion so as to drive the first sliding member to move linearly along a first direction; a second sliding member connected to the first piezoelectrical element, the second sliding member having a second elastic holding portion at bottom thereof; and a second piezoelectrical element connected to the substrate, the second piezoelectrical element having second holding surfaces to be elastically held by the second elastic holding portion so as to drive the second sliding member to move linearly along a second direction intersecting with the first direction, wherein the first elastic holding portion comprises bending segments formed at two sides of the elastic sheet and engaging structures formed at bottom of the bending segments for holding the first holding surfaces, and the engaging structures are selected from the group consisting of curling edges, columns and slide rails.
