Abstract
A film cassette comprising a cassette shell having an end face with an end opening, and a rotatable spool core supported inside the shell with one end protruding through the end opening to outside the shell, is characterized in that a covering label is affixed to the end face of the shell and to the one end of the spool core to prevent rotation of the spool core. The covering label is frangible to allow it to be broken to permit rotation of the spool core and to provide a visible indication the cassette was used. The end face of the shell has a relieved area which immediately surrounds the end opening in the end face along a location beneath the covering label. When the cassette is loaded into a photographic camera, a fracturing piece is received into the relieved area which breaks the covering label.
