ABSTRACT:
A camera for use with a film cassette having a light lock movable to be closed after an exposed filmstrip is wound into the cassette, comprises a chamber for the cassette from which the cassette can be removed, and a driver movable to close the light lock before the cassette is removed from the chamber. An ingress opening to the chamber is provided to admit an insertion tool into the chamber to push the cassette out of the chamber. A cover is movable relative to the ingress opening to uncover the ingress opening after the driver is moved to close the light lock, to permit the insertion tool to be moved through the ingress opening to push the cassette out of the chamber when the light lock is closed. Preferably, a film wind thumbwheel is manually rotatable to wind the exposed filmstrip including a trailing film end portion into the cassette and is coupled with the driver after the trailing film end portion is wound into the cassette to allow the thumbwheel to move the driver to close the light lock when the thumbwheel is further rotated.
