Abstract
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.
