Abstract
Abstract An improved camera and cartridge for use with an assemblage of self-processing film units interconnected by an elongate, relatively flexible, unit-transporting web movable with the cartridge, each film unit including a pair of preregistered, superposed, relatively stiff, substantially flat sheets separably coupled to the web. The camera is provided with a chamber for receiving the cartridge, a spring-loaded member for applying pressure at a predetermined location in the cartridge, a mechanism for advancing the web inside the cartridge, and an exit opening at one end of the camera. The cartridge has a chamber for containing the assemblage, an exit slot at one end of the cartridge in alignment with the exit opening of the camera, through which the pairs of preregistered sheets of the film units are successively transportable along a substantially straight path as the web is moved within the cartridge in response to operation of the web advancing mechanism of the camera, a pressure-bearing and web-guiding member near the exit slot for supporting the web and film units against pressure applied by the spring-loaded member of the camera and for guiding the web along an arcuate path divergent from the straight path of the preregistered sheets to effect separation of the preregistered sheets from the web as the sheets are successively transported along the straight path, and a web take-up device at the opposite end of the cartridge which is rotatable by the web advancing mechanism of the camera for receiving and storing the web and processing waste material from the pressure-bearing and webguiding member after the pairs of preregistered sheets have been separated from the web.
