Abstract
A camera comprising a chamber for a film cassette having a light lock pivoted open to permit film movement into the cassette interior and closed to prevent ambient light from entering the cassette interior, and a lid for closing the chamber, is characterized in that a stop-protrusion is located in the chamber in the way of the light lock, when it is open, to prevent the film cassette from being moved against the lid to move the lid to open the chamber and to be clear of the light lock, when it is closed, to permit the film cassette to be moved against the lid to open the chamber.
