Abstract: Apparatus for storing, transporting, and exposing photosensitive film is disclosed in which a camera supports a table along which a carriage is slidable. The carriage serves to store and feed out lengths of film into a camera exposure station. A vacuum bar is carried by the table at one end thereof so as to underlie one margin of the film. A source of vacuum is connected to the vacuum bar. A sheet of flexible plastic material overlying a translucent platen for the camera is located at the exposure station. Application of vacuum to the vacuum bar causes the film to be flattened against the platen by atmospheric pressure for film exposure.

Abstract: A combined mandrel and core assembly for a camera in which an elongated, cylindrical hollow core, upon which a roll of photosensitive material is carried, is supported by a cylindrical mandrel rotatably mounted within the camera. A spring loaded detent within a slot in the mandrel extends through the slot into a complimentary slot at the midpoint between the ends of the core. The mandrel slot is precisely located upon the longitudinal optical axis of the camera's image plane. The core and its photosensitive material are thereby quickly and accurately positioned along said optical axis. Different widths of photosensitive material may be used upon the same mandrel.

Abstract: Apparatus for storing, transporting, exposing and developing photosensitive film is disclosed in which a camera supports a table along which a carriage is slidable. The carriage serves to store and feed out lengths of film into a camera exposure station. A source of vacuum acting between a sheet of flexible plastic material and a translucent platen for the camera at the exposure station causes the film to be flattened against the platen for film exposure. Thereafter, the vacuum is broken by movement of the carriage and the exposed film is urged into the nip of rollers which carry the film through a developing station supported by the table.

Abstract: A baffle apparatus for a large format camera to prevent non-imaging light coming from the object source and traversing the camera lens from reaching the image plane. A movable opaque baffle is disposed between the camera lens and the image plane. The object source location with respect to the lens and the required position of the opaque baffle are automatically controlled by means of cams driven by a common power source.

Abstract: A photographic printing apparatus in which spaced photosensitive strips are secured to an image plane on top of a housing. An imaging font having two sets of identical symbols in spaced relationship is movably carried upon the housing overlying the photosensitive strips. Light is directed through selected portions of the imaging font upon one of the strips to form a latent image, which is subsequently developed and an instantly visible image on the other strip. The instantly visible image is used by the operator to space subsequent letters or symbols as the printing proceeds.

Abstract: A photoprinting apparatus in which images of symbols on a flat transparency font are projected upon photosensitive material covered by a thin layer of photographic developer. Each symbol on the font is provided with a baseline control indicia and a selected symbol may be projected and viewed prior to exposure employing a light source which will not expose the photosensitive material. Baseline uniformity of the exposed symbols is maintained by sensors which receive an image of the control indicia and regulate the operation of font position adjusting devices prior to each exposure.Novel optical systems, image magnification and minification structures, exposure controls, rapid symbol selection devices, imaging fonts and a cassette for the photosensitive material are also disclosed.

Abstract: A camera accessory to receive a cartridge of photosensitive material and direct the said photosensitive material into a camera. A light-tight enclosure having a door therein permits the cartridge to be introduced into the interior of the accessory. The cartridge is provided with a hollow core upon which the photosensitive material is wound. A light-tight bag of plastic material overlies the photosensitive material. After the cartridge is placed within the enclosure and the door closed, an elongated plunger operable from without the enclosure and extending through the door urges the bag into the hollow core thereby uncovering the photosensitive materials for subsequent feeding into a camera.

Abstract: A photographic copying device capable of storing, exposing and processing both color and black and white photosensitive material including an exposing chamber which can be made light tight for handling color sensitive material or safelight protected for black and white material. Positioning stops in the exposing chamber make it possible to orient photosensitive material in complete darkness. The copying device can be operated in ambient light through light baffles. The material being photographed may be transparent, opaque or in the form of slides. A slide projector section directs light from the slides into the exposing chamber. A central control panel governs all copying operations.
