ABSTRACT:
According to the present invention, a film which has been inserted into a film insertion opening of a support is conveyed toward the inner part reciprocatably by a conveyance means; light is emitted from a light source and is allowed to pass through the film being conveyed; the light which has passed through the film is refracted along the film conveying direction by a refractor; and the light thus refracted by the refractor is received by an optical reader, which reads an image formed on the film. This construction permits the reduction in size of the entire apparatus.
