Abstract
A light image shift correcting device is provided with a planar member having a reference surface perpendicular to an optical axis of a focusing optical system, a shift correcting optical member having a flange portion at its periphery, an urger for movably pressing the shift correcting optical member against the reference surface of the planar member at a plurality of parts of the flange portion, a torus type piezoelectric actuator pressed against the flange portion by a part of the urger, and a controller for controlling the torus type piezoelectric actuator. The device can highly precisely control a light image shift correcting optical member despite its simple construction and can be made smaller.
