Patent ID: 8355051

Claim:
An anti-vibration actuator for moving an image-stabilizing lens within a plane perpendicular to the optical axis thereof, comprising: a fixed portion; a movable portion to which the image-stabilizing lens is attached; movable portion support means for supporting the movable portion so as to permit rotational and translational movement within a plane parallel to the fixed portion; and first drive means, second drive means, and third drive means for generating driving forces in different directions respectively disposed around the image-stabilizing lens for driving the movable portion relative to the fixed portion; wherein the first drive means generates a drive force in approximately the radial direction of a circle centered on the optical axis of an image-stabilizing lens; the second drive means generates a drive force in a direction approximately perpendicular to the drive force of the first drive means; and the third drive means generates a drive force in approximately the circumferential direction of a circle centered on the optical axis of the image-stabilizing lens; and wherein the drive force which can be generated by the third drive means is smaller than the drive forces which can be generated by the first and second drive means.
