Abstract
An instant photocopying apparatus has a rod lens array for imaging fine areas of a manuscript on a photosensitive surface of an instant film. The apparatus has a carrier which is movable in a direction parallel to the manuscript. A flourescent lamp illuminates the manuscript. A filter holder is mounted to the lower end of the carrier, and an optical filter is provided for covering a light incidence portion of the rod lens array. The filter is removably mounted so as to enable changing the exposure and tint of the photosensitive surface of the instant film by mounting or dismounting the filter.
