Abstract: A lens drive device for a zoom optical system drives first and second lenses along an optical axis with a single drive source. A transmission mechanism connects the drive source and the first and second lenses. The transmission mechanism transmits drive to the first lens during a first motion range and to the first and second lenses during a second motion range. A focal length of the optical system changes in the first motion range and a focal point position of the optical system changes in the second motion range. The first and second lenses respectively moves in response to movement of a first and second feed screw. A first gear transmits drive from the drive source to the first feed screw while a second gear intermittently transmits drive from the drive source to the second feed screw. A lock lever interlocks with the second gear in response to rotation of a large diameter section of the first gear to thereby arrest movement of the second gear and second feed screw.

Abstract: A camera, such as a video camera or other electrically recordable camera, has scale imprintable capabilities and a method for imprinting a scale onto memory storage media. The camera and method imprints, optically or electrically, a standard scale on memory storage media for the purpose of estimating the size of a subject image. A photographic magnification calculation circuit calculates the photographic magnification based on a subject distance, and a reference scale setting circuit sets a reference scale for the purpose of estimating the size of the subject image on the memory storage media regardless of the magnification during picture taking or print size. An imprinting circuit imprints, optically or electrically, the reference scale onto the memory storage media in accordance with the reference scale setting circuit, and only when needed or wanted. The reference scale can be imprinted in a vertical or horizontal direction in accordance with a mode selection switch.

Abstract: An optical lens barrel having a lens group which serves as a vibration compensation lens group and a focusing lens group. The lens group is held by a holder movably secured to a plate. The lens group is movable within the plate on a plane perpendicular to an optical axis of the lens group via a pair of DC motors and associated gear trains. The DC motors and associated gear trains are mounted on the plate. The plate is slidably movable parallel to the optical axis of the lens group by a stepping motor via a series of concentric drive rings disposed around the plate. The drive rings also actuate an aperture mechanism which serves as a shutter. This reduces both the number of lenses and components needed to provide vibration compensation and autofocusing functions.

Abstract: A camera displacement mechanism control device can maintain the time required to effect removal of backlash within a set time. Zooming-down is started by the zoom-down switch being turned ON, and the lens barrel is driven as far as the wide-angle terminus if the zoom-down switch is not turned OFF during zooming-down. Alternatively, if the zoom down switch is turned OFF during zooming-down, the lens barrel is driven to the next halt position after the position where the zoom-down switch was turned OFF. In either case, the lens barrel is caused to overshoot the target halt position in the direction of scrolling-in for a time interval long enough to effect removal of backlash, and is subsequently driven in the direction of scrolling-out and halted at the described target halt position.
