Abstract
A film cassette has a hollow cylindrical film takeup shaft rotatably mounted on a side wall of the film cassette and provided with a slit. The slit extends from the free end of the film takeup shaft in the axial direction thereof. A stop larger than the slit is provided on an end of a film which is inserted in the slit. The end of the film is easily and unfailingly connected to the shaft, and the stop prevents the film end from slipping out of the slit.
