Abstract
A copying machine capable of producing variable magnifications has an in-mirror lens and a light for nonuniformly illuminating an original. A stationary member is interposed between the in-mirror lens and a mirror which reflects an image to a photosensitive material. The member has a cut-out portion at an upper edge end thereof so that the member is able to regulate the effective luminous flux transmitted to the sensitive material so that the amount of effective luminous flux transmitted to the sensitive material is maintained substantially uniform along a longitudinal direction thereof at all magnifications of the copier.
