Abstract
A film cassette including a base and a cover, two lock and release slides selectively movable for locking the cover to the base in a closed position and for releasing the cover from the base in an open position, and a linkage for linking the two slides together such that when forces arise on the two slides when a jolt is experienced, the forces on the two slides act against one another. In this way, the chance of such forces leading to movement of the two slides is reduced.
