Abstract
A microfilm image processing apparatus in which a plurality of zoom lenses having different ranges of magnification are provided in a manner that each of the lenses is movable into and out of a position operative to project a beam of light carrying an image on a microfilm strip onto a target plane, wherein the individual zoom lenses are associated with movable members so that the effective magnification of each of the zoom lenses is variable with movement of the associated movable member, and wherein the movable members are interconnected together and are to be driven for concurrent movement by a driving force having a first direction and a second direction opposite to the first direction, the driving force having the first direction resulting in movement of one of the zoom lenses in a direction to increase in the magnification of the lens and movement of another lens in a direction to decrease in the magnification of the lens.
