Abstract
A photographic film cassette has photographic film wound on a spool and rotatably contained in a cassette shell. A leader of the photographic film is caused by rotation of the spool to advance outward from a passage mouth thereof. Two positioning holes are formed in an end face of the cassette shell on an advancing side as inserted into a cassette receiving chamber of a camera, and are fittable on projections of a camera when the cassette shell is loaded therein. Three projections are formed on the end face, and come into contact with an upper inside face of the chamber of the camera when the cassette is loaded in the camera, in order to position the cassette shell vertically. The chamber has an engaging pin, which is engaged with a groove in the cassette shell, to prevent the cassette from dropping out, even when a chamber door is opened downward. A DX code pattern and a use-condition signaling structure are disposed adjacently on the cassette shell, and represent respectively a sensitivity of the photographic film and a condition of use thereof, both of which are detected by a single sensor unit of the camera.
