Abstract
A device for reading bar codes affixed in a predetermined order on an elongated photographic film. The bar codes are provided at the same positions relative to a plurality of image frames that are recorded in the longitudinal direction of the photographic film as the photographic film is being conveyed in the longitudinal direction. The film includes a plurality of symbol reading units disposed parallel to the direction in which the photographic film is being conveyed for reading symbols. The results read by the plurality of symbol reading units are compared with each other, and a determination is made as to whether or not the read symbol is a bar code on the basis of the comparison results. In consequence, it is possible to prevent erroneous detection of bar codes.
