Abstract: To provide an image shake correcting optical apparatus using a small, lightweight engaging mechanism for the correction lens holder engaging mechanism. A ring-shaped engaging member 16 formed of shape memory alloy and having three engaging arms on its inside is located outside a lens holder 11 for a correction lens L3, and the engaging contacts 16b at the tips of the engaging arms 16a are pushed toward the center of the ring-shaped engaging member by means of coil springs 17. The engaging member 16 formed of shape memory alloy has a prescribed memorized shape so that the arms 16a will assume a retracted position, and where no heat is applied, the engaging contacts 16b of the engaging arms press onto the lens holder 11 for the correction lens L3 from the outside due to the spring force of the coil springs 17, and engages with and maintains in place the lens holder 11. Where heat is applied, the engaging arms 16a retract, whereupon the engagement of the lens holder 11 is terminated.

Abstract: A lens driving controller has a driving mechanism for driving a lens along an optical axis, a calculator for obtaining a lens driving amount to an in-focus position, and a detector for detecting a position of the lens. The controller drives the lens in an in-focus direction in accordance with a lens driving amount obtained by the calculator, drives the lens in an opposite direction when the lens reaches a first lens position where a remaining driving amount to the in-focus position is a predetermined value, obtains information on a second lens position when the lens actually starts to move in the opposite direction, obtains a lens movement amount from the first lens position and the second lens position and performs remaining driving to the in-focus position and stop control based on an obtained lens movement amount.

Abstract: In a ring-shaped resilient member, a multiplicity of protrusions inwardly extending from the inner radius are arranged substantially isometrically about the center. When a fork is rotating leftward, the protrusions extending from the resilient member fixed to the inner wall of a housing are bent in the rotation direction of the fork, so that the load imposed on the fork by the protrusions as a frictional force is light. When the rotation direction of the fork is reversed from the leftward direction to the rightward direction, the direction in which the protrusions are swung is also reversed, so that a load is imposed at this time to prevent reversal of rotation of the cartridge spool.

Then, while relatively moving said unit and said wire, another relative position between said unit and said wire is detected as a second position when said second beam is reflected from said wire. Then, a height of said wire from said reference position is calculated based on an interval between said first and second positions.
