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.

摘要： A lens shutter mechanism includes a support frame having a photographing aperture; at least three shutter sectors which open and close the photographing aperture via rotating axes which extend parallel to the optical axis; and at least three diaphragm sectors which vary an aperture diameter formed by the diaphragm sectors to restrict the diameter of the photographing aperture, independently from the shutter sectors, via rotating axes which extend parallel to the optical axis. The support frame is provided with rotational center portions spaced from each other at equi-angular intervals about the optical axis, the number of the rotational center portions being same as each of the number of the shutter sectors and the number of the diaphragm sectors. Each of the rotational center portions rotatably and coaxially supports a one of the shutter sectors and one of the diaphragm sectors.

摘要： A shift mechanism includes first and second ring bodies which are relatively rotatable; a shift cam surface formed on the first ring body on an end surface thereof which faces the second ring body, the shift cam surface being inclined with respect to a circumferential direction of the first ring body; a follower projection formed on the second ring body for engaging with the shift cam surface; and a rotating mechanism for relatively rotating the first and second ring bodies. The shift cam surface and the follower projection are arranged to move the first and second ring bodies toward and away from each other in the axial direction as the first and second ring bodies are relatively rotated. An annular rib is formed along the circumference of the first ring body outside the shift cam surface over the follower projection of the second ring body.
