変倍機構。an optical system for projecting an image of an original onto a photoconductor, at least two mirrors are interposed between a lens in the optical system and the photoconductor, and these two mirrors are mounted on a common mirror holding member; In a copying machine in which the conjugate length is changed during zooming by moving the mirror holding member parallel to the optical axis of the lens, the mirror holding member is attached to a cable that drives the lens. A variable magnification of a copying machine characterized in that by moving the lens with play, the lens is moved at the time of variable magnification.I first determines the position of the mirror holding member, and then adjusts the lens position. mechanism.
