Abstract:
An image reading apparatus, comprising:reading means comprising a plurality of reading sections, wherein the reading sections read an image of a reference position which is used as a reference with respect to a photographic photosensitive material, and determination means for determining a range of reading sections for reading the photosensitive material, wherein said determination means comprises: calculation means which calculates a value which indicates an amount of deviation between an actual reading position, at which the reference position is actually imaged and read by said reading means, and a proper reading position, at which the reference position should be imaged and read; and changing means which changes the range of the reading sections selected for reading the photographic photosensitive material from an initially determined range of the plurality of the reading sections to another range, on the basis of the value indicating the amount of deviation calculated by said calculation means, wherein said reading means carries out preliminary reading and main reading of the photographic photosensitive material conveyed by a conveying means, and said determination means carries out said determination of said range of reading sections, said determination comprises calculating a value that indicates the amount of deviation between said actual reading position and said proper reading position and changing said range of reading sections from the initially determined range to another range on the basis of the value indicating the amount of deviation, after said reading means completes the preliminary reading and before said reading means begins the main reading.
