发明名称 Photographic film cassette, cassette holder and system
摘要 A photographic system is particularly adapted for use in a check security system and offers novel features and advantages for such systems. Such system includes a film cassette and film cassette holder. The film cassette may be molded from plastic parts and can be adapted for assembly and operation without fasteners. The film cassette forms a light tight enclosure with a first opening to admit an image and expose the film within the enclosure and a second opening to permit operation of a film take-up within the cassette. The system includes shutter means adjacent the image-admitting opening of the cassette that can be operated by an actuator carried by the cassette holder. A second actuator carried by the cassette holder can engage and operate the film take-up of the cassette. The cassette can movably carry elements of the system shutter means and provide reliable film take-up and film guidance within the cassette enclosure. The system is capable of being operated in a lighted environment and permits the controlled exposure of film carried within the cassette to a plurality of sequential and separate images focused at the image-admitting opening of the cassette.
