Abstract
A photo film cassette has a cassette shell including first and second shell halves. A spool is rotatable between the shell halves. A trailer of the photo film is retained to the spool. The photo film is wound thereabout in a roll form. A photo film passageway is formed between the shell halves, for passage of the photo film. A shutter is disposed in the photo film passageway in rotatable fashion between open and closed positions to open/close the photo film passageway. A spool lock lever, when the shutter has the closed position, stops the spool from rotating. An indicator plate is secured to one axial end of the spool, for indicating information externally through indicator windows. A partition, disposed inside the cassette shell, defines a photo film chamber and an indicator chamber into which the cassette shell is split. The indicator chamber contains the spool lock lever and the indicator plate in rotatable fashion. A regulating projection is disposed to project on the first shell half and from an inside of the indicator chamber, and prevents the spool lock lever from being inclined toward the indicator plate in the indicator chamber.
