Abstract
PURPOSE: To make it possible for a color copying machine, etc., to form a reflected image and transmitted image on a photoreceptor by fixing an original table and by making it possible to use a slit exposure optical system and entire-surface exposure optical system selectively.
CONSTITUTION: Original T on original table 2 fixed in parallel to screen photoreceptor 1 is irradiated with light from light source 3 for slit exposure and its reflected image passes through slit 5a of optical box 5 and is formed on photoreceptor 1 by way of V-shaped reflex mirror 6 and in-prism lens 7. As box 5 is moved, the real image of original T is formed as a latent image on photoreceptor 1. In duplication of a transmitted image, on the other hand, original T is removed, box 5 is set off the optical path and while light source 3 is turned off, shielding film 10a is placed at the off position to form the optical path for the entire surface exposure. Then, light from light source 3, transmitted through film F, reaches photoreceptor 1 by way of zoom lens 14, reflex mirror 15 and glass original table 2, so that the real image of film F will be formed.
