Photographic film cartridge assembly and still camera.

摘要

Photographic film cartridge assemblies using a disk shaped, rotatable film unit commonly include a cover member which is movable both relative to the film unit and into covering and uncovering relation with a cartridge assembly exposure window. A camera for receiving such a cartridge includes a mechanism for moving the cover member and a mechanism for indexing the film unit.
<??>The problem of simplifying and making more reliable the connections between a still camera and such a cartridge assembly is solved by a cover member (14) which is engageable by the camera indexing mechanism (86) for exposure window (64) covering and uncovering movement and which includes engaging structure (88) cooperable with engaging structure (42) associated with the film unit (10) for rotating the film unit (10) in response to movement of the cover member (14).
<??>The camera (100) includes an indexing mechanism (86) for moving the cover member along a path which both indexes the film unit (10) and covers and uncovers the exposure window (64).
