发明名称 DETACHABLE FILM CHAMBER FOR PHOTOGRAPHIC APPARATUS
摘要 A camera of the self-developing type including an enclosure or chamber coupled to the camera for movement between a compact, inoperative position wherein at least a portion of the chamber is located against a wall of the camera and an extended, operative position in which it forms an extension of the camera and is adapted to receive an exposed film unit as it exits from the camera. The camera includes a pair of rolls for advancing an exposed film unit into the chamber. A switch is located between a source of power and the rolls and is adapted to be closed by movement of the chamber into the extended, operative position thereby insuring that the chamber is in position to receive the exposed film unit prior to the exposed film unit being moved out of the camera.
