<p><P>PROBLEM TO BE SOLVED: To provide a vibration proof actuator capable of movably supporting an image-shake correcting lens, without backlashes, using a simple constitution. <P>SOLUTION: The vibration proof actuator (10) for moving an image-shake preventing lens includes: a fixed part (12); a movable part (14) with an image shake preventing lens mounted; a support arm (17) for linking the movable part and the fixed part for preventing inclination of the movable part with respect to the optical axis, while permitting movement of the movable part; a spherical body (18), held between the movable part and the fixed part; a first driving means, having a first driving magnet (22a) and a first driving coil (20a) disposed facing thereto for driving the movable part, with respect to the fixed part, and a second driving means having a second driving magnet (22b) and a second driving coil (20b), disposed facing thereto for generating a driving force, in a direction which is substantially orthogonal to the driving force of the first driving means. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
