In a production process of a photo film cartridge, data relating to respective components and data obtained during the production process is written in an IC memory that is mounted to a cartridge shell of the photo film cartridge. The data written in the IC memory is read out at later stages of the production process for use in controlling production of the photo film cartridge. The data is at least partly maintained stored in the IC memory after the shipment, for use in tracing production history of the photo film cartridge. When a photo film cartridge having an IC memory is for use in a lens-fitted photo film unit, unit type data indicating the type of the film unit are written in the IC memory before loading the photo film cartridge in the film unit. The unit type data is read out from the IC memory to choose a proper type of packaging materials for the film unit before a unit body of the film unit is wrapped and packed in the packaging materials. |

DETAILED DESCRIPTION In view of the foregoing, an object of the present invention is to provide a method of controlling production of photo film cartridges or film units, which manages a large amount of information necessary for the production at high efficiency, requires less memory capacity to the information supervisory computer, and cuts the cost of information management.
Another object of the present invention is to provide a method of controlling production of photo film cartridges or film units, which enables discriminating the type of each product or semi-product or component efficiently at a low cost during the manufacture.
Still another object of the present invention is to provide a method of managing information on photo film cartridges or film units, which improves traceability of the photo film cartridges or the film units during the manufacture and at the maintenance service.
A further object of the present invention is to provide a method of recycling film units which enables discriminating the type of each film unit and controlling the quality of the recycled film units effeciently at a low cost.
To achieve the above objects, the present invention provides a method of controlling production of a photo film cartridge having an IC memory mounted to a cartridge shell thereof, which comprises the steps of: writing data obtained in a production process of the photo film cartridge in the IC memory; and reading data from the IC memory at later stages of the production process for use in controlling production of the photo film cartridge.
A method of controlling production of a lens-fitted photo film unit comprises the steps of: mounting an IC memory to at least a portion of the lens-fitted photo film unit; writing data obtained in production process of the lens-fitted photo film unit in the IC memory through an access device provided in the unit body for allowing to access the IC memory from outside the unit body; and reading data from the IC memory at later stages of the production process of the lens-fitted photo film unit for use in controlling production of the lens-fitted photo film unit
