ABSTRACT:
The improved slit scanning exposure apparatus has a variable slit assembly that is provided in proximity with the exposing zone and which is composed of two slit plates movable independently of each other in synchronism with the scannning speed. The apparatus may additionally have a color filter that can be inserted into the optical path of reflected light from the image on a document in the scanning direction. The apparatus is capable of preventing flare from being admitted through an exposure slit to a light-sensitive material on the exposure position when it is being exposed from light reflected from the document image. In addition, the apparatus enables more than one document image to be edited into a single image and permits the color filter to be inserted into the optical path of reflected light without causing unevenness in colors.
