ABSTRACT:
In a bottom-loaded camera, a bottom door is manually opened to allow insertion of a film container into the camera and a back door is automatically opened, in conjunction with the opening of the bottom door, to move a pressure plate on the back door to provide space for locating film from the container in the camera. Closing the bottom door closes the back door.
