The zoom lens barrel comprises a driving barrel which rotates about an optical axis of the plurality of lens groups and at least three telescoping barrels which are moved in the direction of the optical axis by rotation of the driving barrel. Each telescoping barrel which is mounted on an inner periphery of another telescoping barrel of the telescoping barrels, travels a greater distance along the optical axis direction than the another telescoping barrel. A lens group driving mechanism is provided for moving the plurality of lens groups in the optical axis direction by movement of the at least three telescoping barrels in the optical axis direction.

摘要： A camera having a zoom lens barrel that includes an aperture size changing mechanism including a pair of light intercepting members which are inserted into a retracted from a rectangular-shaped photographing aperture of the camera for changing the photographing aperture size. The camera further includes a non-rotational cylinder which moves in the direction of the optical axis of the zoom lens without rotating. A rotational cylinder is also included and is driven to rotate with respect to the non-rotational cylinder about the optical axis. A gear supporting member is supported on the non-rotational cylinder. The gear supporting member includes a raised portion projecting toward the photographing aperture. The camera further includes a gear train which is supported on the gear supporting member for transmitting a drive force to the rotational cylinder. At least a part of the gear train is supported by the raised portion, which is formed such that the orthographic projection thereof may not overlap the pair of light intercepting members in the optical axis direction.

摘要： An imaging device includes a rectangular image sensor, and an imaging optical system which includes an on-axis lens element and a radially-retractable lens element. The radially-retractable lens element is supported by a free end of a swingable arm pivoted about an axis eccentric from the imaging optical axis. The on-axis lens element is non-circular, defined by a removed portion from a reference circle thereof along a long side of the image sensor. When in the off-axis displaced position, the radially-retractable lens element utilizes the removed portion of the on-axis lens element and the radially-retractable lens element is offset from a plane through the imaging optical axis and parallel to the short sides of the rectangular imaging surface. The swing axis is on the on-axis lens element side, in the long side direction, closer to the optical axis of the radially-retractable lens element in the off-axis displaced position.
