Photosensitive material scan-exposure method and photosensitive material exposure apparatus

摘要

In a photosensitive material exposure apparatus in which a plurality of rows of photosensitive materials can be subjected to scan-exposure, in a case in which there is only one row of a photosensitive material, scanning is not wasted and exposure time is reduced. Images are exposed by a single scan exposure system in which the column direction of a photographic printing paper (P) is a main scanning direction and a direction orthogonal to the column direction is a sub-scanning direction. In case of single row exposure, scan-exposure is effected only on a necessary row. Accordingly, exposure time can be reduced.
