摘要： Lens barrel has a lens supporting frame to which a frontmost lens group is fixed, a first moving frame to which the lens supporting frame is engaged, a second moving frame to which a rear lens group which is positioned behind the frontmost lens group is supported, and a support frame movement mechanism for moving the first and second moving frame between ready-to-photograph positions and accommodation positions behind the ready-to-photograph positions in an optical axis direction. The support frame movement mechanism makes the first moving frame and the second moving frame rotate about the optical axis relative to each other with the lens supporting frame and the second moving frame being in contact with each other when the first moving frame and the second moving frame are positioned in the vicinity of accommodation positions. One of the lens supporting frames includes a low-frictional portion provided on a contacting surface thereof.

摘要： A zoom lens barrel includes a cam ring which is driven to rotate; a first lens frame which is positioned around the cam ring, supports a frontmost lens group of a zoom lens system, and includes a first cam follower; a light-shield exterior ring positioned around the first lens frame, and includes a second cam follower; and first and second outer cam grooves formed on an outer peripheral surface of the cam ring so that the first and second cam followers are engaged in the first and second outer cam grooves, respectively. The second cam follower is engaged in the second outer cam groove through a linear guide slot formed on the first lens frame. Zooming ranges of the first and second outer cam grooves are shaped so as to move the first lens frame and the light-shield exterior ring in the same moving path.

摘要： A retracting mechanism of a zoom lens barrel includes first, second and third lens groups, wherein the first and third lens groups are integrally moved along an optical axis during variation of a focal length, and wherein at least one of the first and third lens groups is moved relative to the other to reduce a distance therebetween when the zoom lens barrel is fully retracted. The retracting mechanism includes first, second and third lens group moving rings; a cam mechanism for independently moving the first and second lens group moving rings; a second lens group support frame; an intermediate member fixed to the second lens group support frame; and a biasing device for biasing the third lens group moving ring away from the first lens group moving ring. The biasing device functions between the intermediate member and the third lens group moving ring.
