    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 barrel includes a cam ring which is rotated about an optical axis to move a lens group in the optical axis direction via a cam groove formed on the cam ring, and a rotational ring which transfers a rotational motion to the cam ring. The rotational ring includes a rotation-transmission arm extending in the optical axis direction. The cam ring includes an engaging recess formed on an outer peripheral surface of the cam ring, and in which the rotation-transmission arm is slidably inserted to be movable in the optical axis direction, and an outer flange formed on an outer peripheral surface of the cam ring to form a slot penetrating therethrough in the optical axis direction between the outer flange and a bottom radial surface of the engaging recess so that the rotation-transmission arm is slidably fitted in the engaging recess through the slot.

    摘要: A focal length detector of a camera having a zoom lens includes a brush having three sliding contacts which are electrically connected to one another; a code plate having three code patterns and a ground pattern, the code plate and the brush being moved relative to each other according to a variation of the focal length of the zoom lens; and a focal-length detecting circuit which is connected to the three code patterns and the ground pattern. The ground pattern always contacts a specific sliding contact of the three sliding contacts. The three code patterns are arranged so that the three code patterns come into contact with the remaining two sliding contacts in predetermined combinations when the code plate and the brush are moved relative to each other.

One end of the first guide shaft is secured to the second member. A screw shaft extends in the direction of the optical axis and has a first thread, where one end of the screw shaft is secured to the second member and the screw shaft is positioned adjacent to the first guide shaft. A device for detecting whether the lens group is located at an extremity of a predetermined movable range of the lens group relative to the first member along the optical axis is also provided. The detecting device includes a connecting member secured to the other end of each of the screw shaft and the first guide shaft.
