Abstract
Abstract A film cartridge comprises a chamber in which a film is contained and a semiconductor memory such as nonvolatile memory, e.g., E<2>PROM having a plurality of memory areas for storing various kinds of photographing data of each photography. In this semiconductor memory, photographing data are stored in different areas at each photographing and therefore the preceding photographing data stored in the memory are not deleted by this time photographing and photographing data of a desired film frame are accessible. Data used at a photo processing shop and a photofinishing laboratory can be also stored in the memory of the film cartridge.
