CONTINUOUSLY VARIABLE REDUCTION SCANNING OPTICS DRIVE

摘要

A continuously variable reduction imaging system for an electrophotographic copier machine is provided, comprising a glass platen upon which a document to be copied is placed; a mount for carrying photoreceptive material; main motive means for moving said amount and source of illumination, a document scanning system comprised of a scanning carriage for directing illumination from said source to said document: means for driving said scanning carriage; an optics system for directing illumination from said document to produce an image on said photoreceptive material, said optics system including a lens; and an optics positioning system wherein said lens is adjusted in a continuously variable manner whereby the magnification ratio of said imaging system may be set in a continuously variable manner between two boundaries.
