Abstract:
1. An apparatus for processing a photosensitive material centered with respect to a center of a transport path, in which said photosensitive material is processed while traveling along said transport path, said apparatus comprising: a plurality of photosensitive material detectors for detecting the presence or absence of said photosensitive material traveling alone said transport path, said plurality of photosensitive material detectors being arranged across the width of said photosensitive material, in an asymmetrical manner with respect to said center of said transport path; and a recognition part for recognizing the width of said photosensitive material based on how many of said plurality of photosensitive material detectors have detected the presence of said photosensitive material; wherein said plurality of photosensitive material detectors are alternately arranged on both sides with respect to said center of said transport path, in the order in which a distance from said center of said transport path increases.
