したことを特徴とする複写機の変倍機構。an optical system that sequentially sends slit light from an original to a lens via first, second, and third mirrors, and sends the slit light that has passed through the lens to a photoreceptor via a fourth mirror; A document moving type copying machine in which the second and third mirrors are fixed to a common mirror holding member, and 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 caused to follow the lens with a large amount of play, so that when changing magnification, the lens is moved to first determine the position of the mirror holding member, and then the lens position is adjusted. The variable magnification mechanism of a copying machine.
