ABSTRACT:
A film cartridge comprises a cartridge shell for housing a filmstrip, and a coded mechanism for providing an indication of one or more properties of the filmstrip. The coded mechanism includes a cavity formed in the outside of the shell to be accessible, a cover affixed to the outside of the shell that completely covers the cavity, and at least one cut-out in the cover uniquely positioned over the cavity to permit entry into the cavity only through the cut-out to provide an indication of one or more properties of a filmstrip housed in the shell.
