Abstract
A lens is moved by a lens moving member in the direction of its optical axis, and a mirror group is moved by a mirror moving member in the direction of the optical axis of the lens. The moving ranges of the lens moving member and the mirror moving member overlap, and the mirror moving member and the lens moving member are moved at different rates or times such that the mirror moving member and lens moving member do not interfere. A flexible light shielding member on the lens moving member blocks non-image forming light from reaching the mirror group, but bends within a housing holding the moving members to allow the lens moving member to move in its full moving range. A pivotable light shielding member in the moving range of the lens moving member blocks non-image-forming light from reaching the mirror group, but pivots when the lens moving member is moved in contact with it, allowing the lens moving member to move in its full moving range.
