Abstract: An apparatus for automatically and incrementally feeding a continuous fan-folded document to be copied having interconnected segments over a bed plate of a flash illumination photocopier for sequentially positioning each document segment on the bed plate. A drive assembly engages and moves the document having a motor supplying motive power to the drive assembly. The motor is coupled to the drive assembly through a clutch that controls the supply of motive power. A brake is coupled to the drive assembly to stop document movement when the clutch is disengaged to position each document segment on the bed plate. A control mechanism automatically engages the clutch and releases the brake to feed a subsequent document segment to the bed plate after a copy run of a given document segment has been completed. Engagement of the clutch and release of the brake is initiated simultaneously with the last flash in the copy of the photocopier illuminating strobe lamps.

Abstract: A microform data acquisition processing and storage system in which data is fed from a computer, tape or cards to a cathode ray tube from whence an image produced on the tube is projected onto a photographic film or alternatively by means of an optical switching device an image of a document located on a document platen within the apparatus can be projected on to the same film without changing the film; the cathode ray tube is provided with a coating having a spectral peak between 500 and 600 nm so as to match the spectral peak of the image on the platen.

A photoelectric device mounted on a yoke for detecting a perforated hole in the film. A control device for stopping the feed of the film track in response to the detection of the perforated hole, and actuating a printer print cycle substantially simultaneously therewith, and subsequently automatically feeding the film track again.

Abstract: Apparatus for exposing an image of a desired pattern, such as a lead frame pattern for producing lead frames of IC devices, with a predetermined pitch on a photosensitive beltlike material consisting of a film carrier and a photoresist-coated metallic foil laminated on the carrier.Apparatus typically comprises a first means for positively supporting and accurately positioning the beltlike material at an exposing position, a second means for intermittently conveying the material and a third means for photoelectrically detecting the amount of the movement of the beltlike material to control the first and the second means.

Abstract: An enlarger-printer wherein aperture cards, each mounting a microfilm, are fed one after another from a card hopper, moved in the direction in which the major sides of the cards are oriented and scanned in the direction in which the minor sides of the cards are oriented, so that imagewise exposing of a photosensitive member can be effected for each card to form an enlarged latent image of the film of each card on the photosensitive member, which latent image is then converted into a visible image. Before each card is scanned, the card is moved upwardly a distance corresponding to the margin between the image and the upper edge of the film to reduce the time required for effecting scanning. Switching between lenses of different magnifications, exposing slits of different widths and scanning speeds consistent with desired magnifications of the image can be effected simultaneously by simply actuating a lever.

Abstract: A camera for photographing information on microfilm comprises structure defining an image aperture, a lens system for projecting an image of the information to be photographed along an optical path through the image aperture, and a device for selectively clamping microfilm against the image aperture defining structure. The image aperture defining structure and the clamping device are mounted and restrained against lateral movement relative to the optical path. A carriage is movable relative to the image aperture defining structure, the lens system and the clamping device, and carries equipment for advancing microfilm between the image aperture defining structure and the clamping device.A photographic film handling apparatus wherein photographic film is positioned at a structure defining an image aperture comprises a film pressure plate having a cluster of air holes for an escape of air from a space between the film pressure plate and adjacent photographic film.

Abstract: A step and repeat camera is disclosed which includes a module for supporting a supply of film material, for metering a length of film material from the support and cutting the film to a predetermined length, a second module for supporting the cut sheet of film with the light sensitive coated surface positioned downward and moving the film along X and Y coordinates to position successive areas of the film over an image projecting lens. The support moves the film from a first film receiving conveyor to a titling area where a title is contact exposed onto the film, through the imaging section along the coordinates, and to the discharge conveyor. The third module includes apparatus for conveying the film over a DC corona bar which causes the film to adhere to a hot processing drum and to be carried thereby under a heated shoe past an AC corona bar to discharge the film, permitting the same to drop from the surface of the drum across its initial infeed path into a cooling chute.

Abstract: Microfiche or microfilm cameras which are provided with a variable format masking assembly and a facility to change the reduction ratio. In two constructions of the camera the head of the camera remains fixed with relation to the base. In one construction the photographing lens is movable in the head along the optical axis for change of reduction ratio and in this construction a mirror is provided in the head between the lens and copying table. In a second construction the copying table is movable into a well in the camera base and lighting may be provided into the well. In order to use microfiche film more economically various new microfiche layouts are devised as being suitable for these cameras.

Abstract: Apparatus for preventing successive jamming of copy sheets in copying apparatus of the type including a forwarding mechanism for moving a copy sheet along a running path through a treatment zone for forming a visible image on the copy sheets and a copy sheet feeding mechanism, the successive jamming prevention apparatus including one or more detecting members disposed at detecting points in the running path so that at least one of the detecting members will contact a copy sheet at any position in the running path, a switch having normally closed contacts opened in response to contact of any of the detecting members with a copy sheet to prevent actuation of the copy sheet feeding mechanism and normally open contacts closed in response to contact of any of the detecting members with a copy sheet to provide an alarm signal.

Abstract: A microfiche is titled by synchronously and incrementally imaging title information having a rotary motion upon the film carrying the microfiche that has a linear motion. Selectable drums carry the title information. Image-forming means transfers this information for the exposure of microfiche film. Equivalent motor means drive both the drum and the microfiche film. Electronic control logic connected to both of the motors accomplishes synchronous motion so that the title information is fixedly impressed with respect to the microfiche film despite the fact that both are in motion.

Abstract: Photographic film handling equipment is disclosed, wherein photographic film is positioned relative to a photographic lens system. The film is advanced in a first direction by a film transport mounted on a carriage which is restricted by bars to movement in opposed parallel second and third directions. The carriage is driven via an endless timing belt disposed in a loop having a straight portion extending parallel to the latter second and third directions. Motive power is transmitted from the timing belt to the carriage by a bracket connected to the straight loop portion of the timing belt. A motor drives the timing belt in opposite senses.

Abstract: A copying apparatus with a document copying platen, including a substantially uniformly light reflective platen cover for holding documents against the platen, and including document drive wheels having light reflective constant width surfaces partially extendable through fixed apertures in the platen cover towards the platen. The fixed apertures in the platen cover are wider than the drive wheels to allow their limited transverse movement. Light reflective shields having an aperture the same width as the wheels are mounted in the platen cover so that each wheel extends through a light shield aperture with each light shield closely fitted to both sides of a wheel. Each light shield is movable transversely together with its wheel, but each light shield constantly overlies its fixed aperture in the platen cover irrespective of this transverse movement to constantly present a substantially uninterrupted light reflective surface over the platen together with the wheel.

Abstract: An exposure device is adapted to intermittently feed a metal strip with each surface coated with a photosensitive film and expose it from both sides when the metal strip stops its movement. The device includes a feed setting mechanism comprising a detection roller rotated in accordance with the movement of the metal strip, a detection bar longitudinally movable by the movement of the detection roller, and a switch actuated, when the detection bar is moved a predetermined amount, to stop the movement of the metal strip.

Abstract: Apparatus for electrophotographically imaging a photosensitive film in which a fractional area of the film, selected by automatic or preprogrammed access, is electrostatically charged and thereafter exposed to a pattern of radiation, is moved along a path of travel to a second location at which the latent image is developed by the application of toning fluid, and is preferably returned along the path of travel to fix or fuse the developed image as a next adjacent area is indexed for exposure. Additional areas of the film may be sequentially imaged by repeating the above sequence or by reinserting the partially completed film at a later time and addressing any desired used or unused area.

Abstract: A microfilm recording machine of the type which makes a photographic reproduction of each document processed therethrough has an improved document transport system for presenting the documents in a predetermined focal plane within the machine document scanning zone. The transport system includes a single glass plate having a longitudinal major surface within the predetermined focal plane and a transverse axis forward of the major surface. A pair of cooperating transport rollers on each side of the glass plate form nips for engaging the documents. The nips are forward of the glass plate major surface and the rollers are rotatable about axes to transport each document through the scanning zone. The plane embracing the axes of rotation of each respective roller pair converges upon the transverse axis so that each document is directed toward and against the major surface as it is transported through the scanning zone.
