Abstract
A photographic film having a bar code formed in the vicinity of one side edge thereof is longitudinally moved while being guided by a mount. An optical fiber bundle which moves while following one widthwise end surface of the photographic film reads the bar code on the film. The optical fiber bundle follows any change in width of the photographic film and therefore constantly coincides with the bar code to effect correct reading thereof.
