Abstract
An image input apparatus for an image scanning reading apparatus comprises a cylindrical holder for holding a plurality of originals and reference portions for calibration serving as references in reading original, a scanning head for scanning the original holder, and a memory for storing positions of the reference portions for calibration. The position of the reference portion for calibration is stored prior to the reading of the original, and when the scanning is started, the scanning head is moved to the stored position, the reference data for calibration is read by the scanning head at that position, and the corresponding original is read based on the data.
