うにしたことを特徴とする複写機の変倍機構。In a copying machine equipped with an optical system that projects an image of an original onto a belt-like photoreceptor, a mirror interposed between a lens in the optical system and the belt-like photoreceptor is aligned with the optical axis of the lens. By moving in parallel, the conjugate length is changed during zooming, and by making the mirror holding member that holds the one mirror follow the lens with a large play, the lens is moved first during zooming. A variable magnification mechanism for a copying machine, characterized in that the position of the mirror holding member is determined and then the lens position is adjusted.
