PROBLEM TO BE SOLVED: To provide an image reading apparatus capable of correctly detecting the head end or the rear end of a film, i.e. the position of the film itself in a film carrying path, clearly reading an image and printing it, and ensuring high accuracy for calculation of the length of the film. SOLUTION: The image reading apparatus is provided with a carrying mechanism 4 for carrying a photographic film F along a carrying path, a processing mechanism provided on the halfway of the carrying path and for performing processing for the photographic film F, an accommodating space for taking up the photographic film F carried along the carrying path and accommodating it, and an image reading mechanism for reading and printing an image formed on the photographic film F. The apparatus has, on the halfway of the carrying path, guides G1, G2 for restricting the photographic film, a light-emitting section and a light-receiving section, and is provided with reflection type optical sensor S using a portion near the surface of the restricted photographic film as a reflection point.
