    摘要： A zoom camera includes a lens that is movable from a housed position to an arbitrary position in a photographing enabling range. A lens driver drives the lens, a lens barrier moves between opened and closed positions, and lens barrier closing mechanism moves the lens barrier between an opened position and the closed position. A detector detects that the lens has moved from a position within the photography enabling range to the housed position and controller prevents the lens barrier closing mechanism from moving the lens barrier to the closed position unless the lens is at the housed position.

    摘要： A zoom camera has a lens barrier apparatus, a front lens group, a rear lens group, a rear lens group is lens barrel that houses said front lens group and said rear lens group, said rear lens group is supported such that a distance between the front lens group and the rear lens group is changeable, and the lens barrel is movable between a housed position, at which the lens barrel is retracted furtherest with respect to the camera body, and a photo-ready range, at which the lens barrel is extended from the housed position. A rear group moving device is mounted on the lens barrel, for moving the rear lens group relative to the front lens group. An entire movement device moves the lens barrel without changing a distance between the front lens group and the rear lens group, and a lens barrier apparatus, which is provided with barrier blades that are mounted on the front end of the lens barrel is provided. The rear group moving device is connected to the lens barrier apparatus and drives the lens barrier apparatus to operate the barrier blades when the lens barrel is at the housed position and is connected to and drives the rear lens group relative to the front lens group when the lens barrel is extended from the housed position.

    摘要： A camera with lens barrier apparatus in which the lens barrier apparatus is driven by a motor that is also used to drive another mechanical element in the camera. The motor is switched between the lens barrier apparatus and the mechanical element by the movement of a lens barrel. In this arrangement, the driving of the lens barrier apparatus and the mechanical element are controlled in accordance with the output of a single sensor, for example an encoder.The driving of the lens barrier apparatus is controlled such that the barrier will not close unless the lens barrel is at the housed position and such that if the lens barrier does not open, the lens barrel will not move. The driving is further controlled such that if the lens barrier apparatus does not move to its intended state, the drive is reversed prior to again attempting to drive to the intended state.The lens barrier apparatus is mechanically arranged such that barrier blades are nonresiliently driven during a portion of the closing or opening operation and are resiliently driven during the remainder of the closing or opening operation.
