Abstract
Film carrier detecting mechanism is provided to detect a film carrier positioned at an image reading position to find to what size of film the film carrier is applied. Optical system driving mechanism is controlled according to the size of a film detected by the film carrier detecting mechanism, and varies magnification of image forming optical system so that the width of a film image formed on the surface of photoelectric conversion element is kept constant irrespective of the difference in size of film. Image processing circuit processes and regularize an image reading data corresponding to the size of a film detected by the film carrier detecting mechanism based on a corresponding reading condition.
