Photo film and method of inspecting the same

A method of inspecting plural photo films of a single type produced in one lot, wherein each of said photo films has a pair of edge portions extended in a longitudinal direction, plural image frames are photographable between said edge portions, and plural bodies of photo film information associated with said single type are recorded in at least one of said edge portions photographically in a predetermined arranging pattern in the form of latent images, said photo film inspecting method comprising steps of:

• designating a discriminating code in association with said arranging pattern, the discriminating code adapted to discriminate said arranging pattern;
• storing the discriminating code in a memory;
• recording the discriminating code photographically on said photo films in the form of a latent image when said photo film information is recorded;
• sampling at least one of said photo films included in said one lot;
• developing said sampled photo film at least partially, to render the discriminating code recorded thereon visible;
• reading the discriminating code from said developed sampled photo film;
• and
• checking whether the discriminating code read from said developed sample coincides with the discriminating code stored in the memory, wherein, if the discriminating code read from said developed sample is different from the discriminating code stored in the memory, then it is judged that said photo films included in said one lot have a wrong arranging pattern.

A system for producing plural photo films of a single type produced in one lot, each of said photo films having a pair of edge portions extended in a longitudinal direction, wherein plural image frames are photographable between said edge portions, said photo film producing system comprising:

• a code generator device for generating a signal of a first discriminating code, said first discriminating code determined in association with said single type of said photo films;
• a pattern memory for storing plural arranging patterns at an address of said first discriminating code, each of said arranging patterns associated with a photo film type, and adapted to arranging plural bodies of photo film information associated with said photo film type, said arranging patterns respectively determined so as to arrange said photo film information in at least one of said edge portions in fashion usable after being developed;
• a computer, connected to said code generator device and said pattern memory, for accessing said pattern memory in response to said signal of said first discriminating code, and for reading one of said arranging patterns associated with said first discriminating code;
• a side printing apparatus, connected to said computer, and supplied with a signal of said arranging patterns and said signal of said first discriminating code by said computer, for photographically recording said photo film information in said at least one of said edge portions in said read arranging pattern in form of latent images, and for recording said first discriminating code photographically on said photo films in form of a latent image;
• a sampling section, connected to said side printing apparatus, for sampling at least one of said photo films included in said one lot;
• a photo film processor, connected to said sampling section, and supplied with said sampled photo film, for developing said sampled photo film at least partially, to render a second discriminating code visible;
• and
• a code reader, connected to said computer and said photo film processor, for reading said second discriminating code from said developed sampled photo film;
• said computer, supplied with information of said second discriminating code by said code reader, and checking whether said second discriminating code coincides with said first discriminating code, wherein, if said second discriminating code is different from said first discriminating code, then it is judged that said photo films included in said one lot have a wrong arranging pattern.
