Abstract
A lens-fitted photo film unit includes a housing which incorporates an exposure mechanism and is pre-loaded with photo film. A packaging cardboard covers the housing. An identification sign is disposed outside the housing in externally readable fashion, and signals information of one kind of the housing. In classification of the photo film unit, the packaging cardboard is removed from the housing. The identification sign is read, to detect the one kind of the housing. Three downstream paths are disposed and respectively associated with three kinds of housings. The housing is transferred to one of the downstream paths in association with the detected one kind. In a preferred embodiment, the identification sign includes a combination of smooth and rough faces, which are different in optical reflectance from one another. The combination constitutes the information of the one kind of the housing. Preferably, a lower critical value is determined for a surface roughness of the rough face. A lower critical ratio in surface roughness is determined between the smooth and rough faces.
