PROBLEM TO BE SOLVED: To provide a lens barrel which can be further miniaturized. SOLUTION: The lens barrel 3 includes an optical system O, a corrective lens support mechanism 290, a correction drive unit 289, a retractable lens frame 250, and a retraction drive mechanism 295. The optical lens O includes a corrective lens group G3b and a retractable lens group G3a. The corrective lens support mechanism 290 movably supports the corrective lens group G3b in a direction perpendicular to the optical axis A of the optical system O. The correction drive unit 289 drives the corrective lens support mechanism 290 so that the corrective lens group G3b moves in a direction perpendicular to the optical axis A. The retractable lens frame 250 supports the retractable lens group G3a to a first retractable position P1 so as to be retractable. The retraction drive mechanism 295 drives the retractable lens frame 250 so that the retractable lens group G3a retracts to the first retractable position P1. COPYRIGHT: (C)2011,JPO&INPIT |
