摘要： A lens barrel includes a non-rotatable annular ring and a circumferential guide groove; a first rotatable ring supported inside the annular ring and including a rotation-guiding projection slidably engaged in the circumferential guide groove; a second rotatable ring which rotates with the first rotatable ring and is only axially movable relative to the first ring, including an engaging projection slidably engaged in the circumferential guide groove with the rotation-guiding projection, wherein the engaging projection is insertable/removable from the circumferential guide groove through the insertable/removable aperture at a first assembling/disassembling angular position; and a coupling ring which is positioned inside the first and second rotatable rings. A coupler provided between the coupling ring and the second rotatable ring is disengaged at a second assembling/disassembling angular position. The first and second assembling/disassembling angular positions are substantially the same.

摘要： A lens barrel includes a holder holding an image pick-up device; a stationary barrel having a female helicoid; a gear/helicoid ring including an annular rib, a male helicoid formed on the annular rib and engaged with the female helicoid, and a spur gear formed on the male helicoid; a pinion engaged with the spur gear; a linear guide ring provided around the gear/helicoid ring; a outer circumferential groove formed on the gear/helicoid ring; and bayonet lugs projecting rearwards from the linear guide ring and engaging in the circumferential groove. Rotation of the gear/helicoid ring causes a lens group to move along the optical axis. At least a portion of a rear end of the male helicoid extends rearwards. At least a portion of the rear extension portion overlaps the holder in the optical axis direction when the gear/helicoid ring stops retracting at a predetermined position.

摘要： A retractable barrel includes a rear holder which holds a rear optical element on an axis, the rear holder having a recess; an annular member movable towards and away from the rear holder without rotation; a retractable holder, accommodated within the annular member, which holds a retractable optical element, and being movable between a position where the retractable optical element is aligned with the axis, and a position where the retractable optical element is displaced from the axis; a position controller which controls the annular member and retractable holder to move between an operational position to a retracted position wherein the retractable holder is at the displaced position. A movement path of the retractable holder includes an oblique path extending obliquely to the axis. The recess prevents the rear holder from interfering with the retractable holder.

摘要： An eccentricity-prevention mechanism includes a pair of lens-supporting rings for supporting a pair of lens groups, respectively; and a pair of positioning recesses and a follower projection formed on one and the other of opposed surfaces of the pair of lens-supporting rings, such that the follower projection engages with one of the pair of positioning recess to define a relative position of the pair of lens-supporting rings with respect to the optical axis, at a mutually close position and at a mutually distant position. At least three pairs of the positioning recesses and at least three follower projections are provided at different positions in a circumferential direction, so that eccentricity between the pair of lens-supporting rings is eliminated when all of the follower projections are concurrently brought into engagement with corresponding positioning recesses.
