倍装置。 Variable magnification type copying that copies by changing the total optical path length from the document surface to the exposed surface of the drum-shaped photoreceptor and the optical path length from the lens to the exposed surface of the photoreceptor in accordance with the copying magnification without changing the focal length of the lens. In the machine, a mirror is movably disposed from the lens to the exposure surface of the photoconductor, and the upper and lower portions of the mirror are connected to two winding means through two flexible members. A spring is attached to apply tension to the flexible member, and the two winding means move the mirror to change the total optical path length and transfer the light reflected by the mirror to the drum-shaped photosensitive member. A copying magnification changing device characterized in that the mirror is formed in a shape that allows the mirror to be oscillated so as to direct the mirror toward the center of the body.
