Abstract

A production managing method for production of motion picture photo film is provided. At first, film web is slitted to produce continuous photo film having a predetermined width. Production managing information is written to an RFID (radio frequency identification) tag, and includes a roll number and slitting number, which are related to the film web and the continuous photo film. The continuous photo film is cut to produce motion picture photo film. The production managing information is stored in association with the motion picture photo film. The motion picture photo film is checked. If the motion picture photo film has a defect, the production managing information may be referred to for detecting a portion of the film web or the continuous photo film from which the defect derives. Other motion picture photo films with a defect will be traced.

Claims

1. A production managing method for photo film production, comprising steps of:

slitting film web having a great width to obtain plural continuous photo films having a small width, said film web being unwound from a master roll;

forming plural continuous photo film rolls by winding said continuous photo films about respectively first spools, said continuous photo films being subjected in a subsequent process to treatment to obtain a photo filmstrip having a predetermined length; and

attaching a first non-optical recording medium to each one of said rolls, said recording medium storing information related to at least said film web, and being read in said subsequent process for use in managing said photo film production in said subsequent process.

2. A production managing method as defined in claim 1, wherein said information includes an identification number and type information of said continuous photo films.

3. A production managing method as defined in claim 2, wherein said information further includes a lot number information, master roll information of said master roll, and defect information, said defect information is adapted for specifying other continuous photo films in estimation of being similarly defective by referring to said lot number information and said master roll information.

4. A production managing method as defined in claim 2, wherein said first recording medium is attached to said one roll after said information is written thereto.

5. A production managing method as defined in claim 2, wherein said information is written to said first recording medium after being attached to said one roll.

6. A production managing method as defined in claim 2, wherein said first recording medium is attached to each of said first spools.

7. A production managing method as defined in claim 6, wherein said first recording medium is removable from each of said first spools.

8. A production managing method as defined in claim 2, wherein said first recording medium comprises a fastening sticker attached to an end portion of each of said continuous photo films for preventing said rolls from being loose.

9. A production managing method as defined in claim 2, wherein said subsequent process includes steps of:

drawing a continuous photo film from said one roll;

perforating said continuous photo film; and

forming a perforated continuous photo film roll by winding said continuous photo film about a second spool, to obtain a perforated roll.

10. A production managing method as defined in claim 9, wherein said information read from said first recording medium is written to a second recording medium attached to said second spool, said continuous photo film being wound about said second spool.

11. A production managing method as defined in claim 9, wherein said first recording medium is removed from said one roll, and attached to said perforated roll.

12. A production managing method as defined in claim 9, wherein said first and second recording media are non-contact IC memories.

13. A production managing method as defined in claim 9, wherein said first and second recording media are wireless non-contact ID tags.
