<P>PROBLEM TO BE SOLVED: To propose a lens drive device that drives a lens in the optical axis direction and corrects camera shake. <P>SOLUTION: The lens drive device includes: a first holding body 2 holding a lens and moving it in the optical axis direction (Z-direction); a second holding body 3 which movably holds the first holding body 2 in the Z-direction; a fixing body which movably holds the second holding body 3 in the direction approximately orthogonal to the Z-direction; an elastic member 8 which has a fixing part 8b and a deforming part 8d to the second holding body 3; and a plurality of wires 10. The second holding body 3 is supported on the fixing body so as to be movable in the direction approximately orthogonal to the Z-direction by the wires 10. The deforming part 8d is elastically deformed in the Z-direction with a smaller force than the buckling loads of the wires 10. The wire 10 having one end fixed to the deforming part 8d and the other end fixed to the fixing part, is inclined in the Z-direction so that one end is expanded than the other end when viewed from the direction approximately orthogonal to the Z-direction. <P>COPYRIGHT: (C)2011,JPO&INPIT |
