Image reading apparatus

An automatic focusing (AF) control section performs focus detection for each of focusing regions provided in an image reading area to detect positions of an image-forming lens where the focusing regions are focused as partial focusing positions. A loading condition judgment unit judges the loading condition of a photographic film by inspecting a curl of the image reading area based on each of the partial focusing positions. When the image reading area is bowed such that the center thereof is projected toward an area CCD, the photographic film is judged being loaded in reverse, and a warning message is displayed on a display. In this case, image reading of the photographic film is not executed.
