Abstract

PURPOSE:To adjust the length of an optical path automatically according to magnification and form an original image on a photosensitive surface correctly by shifting a mirror in position through a cam mechanism associatively with a manual shift in lens position. CONSTITUTION:Reflected light from the original is changed in direction by the mirror 9 to travel to a photosensitive drum through a lens 11. A manual dial 29 is rotated to displace a lens mount 24 through a chain 27, and the lens 11 is thus shifted in position to vary projection magnification. The optical path length from the original to the photosensitive surface should be adjusted associatively, so a cam follower 34 is moved by a cam 32 provided to the lens mount 24 to displace a rack 35 where it is supported pivotally. The rack 35 rotates a pinion 36 to displace the mirror 9 through a chain 39, pinion 41, and rack 42, so the optical path length is adjusted automatically.

Copying is performed by changing the optical path length from the document surface to the exposed surface of the photoreceptor without changing the focal length Z of the lens.The copying magnification 7 is performed by changing the optical path length from the document surface to the exposure surface of the photoconductor.On the side of the summer type recovery mode, a manual copying magnification setting means and a manual copying magnification setting means are provided. A lens position adjusting means is connected to the copying magnification setting means and is capable of changing the position of the copying lens in the direction of the original axis. 'Changing the optical path length from the document surface to the exposure surface of the photoreceptor to the optical path length necessary to form an image on the photosensitive light surface of the photoreceptor is one step.' Copying magnification variable device for copying machines.
