Abstract
Continuous photo film includes a support of resin film having a back surface. A photosensitive layer of photographic emulsion is disposed on a surface of the support opposite to the back surface. A conveying roller conveys the continuous photo film. The conveying roller includes a roller body of metal. A hardness reinforcer layer is formed on a surface of the roller body by thermal spraying of ceramic or cermet, so that the roller body surface is prevented from being scratched or ground by the back surface of the film.
Claims11
A conveyor guide rail for guiding continuous photosensitive material being conveyed, comprising:
- a guide rail body of metal, extended in a longitudinal direction of said photosensitive material, including a conveying surface along which said photosensitive material is conveyed;
- a hardness reinforcer layer, formed on at least one part of said conveying surface, having higher hardness than hard chrome plating, for contacting said photosensitive material;
- wherein at least one part of said hardness reinforcer layer or said at least one part of said conveying surface is polished and smoothed;
- and
- wherein the conveyor guide rail further comprises a photosensitive material guided by the guide rail body.
A photosensitive film manufacturing apparatus, comprising:
- a photosensitive film supply unit;
- conveying rollers;
- and
- a conveyor guide rail for guiding continuous photosensitive material within the apparatus, the conveyor guide rail comprising:
- a guide rail body of metal, extended in a longitudinal direction of the photosensitive material, including a conveying surface along which the photosensitive material is conveyed;
- a hardness reinforcer layer, formed on at least one part of the conveying surface, having higher hardness than hard chrome plating, for contacting the photosensitive material;
- wherein at least one part of the hardness reinforcer layer or the at least one part of the conveying surface is polished and smoothed.
