Abstract
There is provided an image stabilizing unit 1 small in size in one direction perpendicular to an optical axis, including, on a base member 2, a movable compensation member 5 which can displace an image forming position by moving in a plane perpendicular to an optical axis Z, and two drive units 6, 7 for displacing the movable compensation member 5 in the directions of R and S which are different from each other for 90 degrees, wherein the directions in which the drive units 6, 7 respectively move the movable compensation member 5 are inclined 45 degrees to a direction X which connects the drive units 6, 7 and the optical axis center Z of the movable compensation member 5.
