  • Patent number: 4135810
    Abstract: A web of copying material is transported on-edge through an exposure-station web guidance system provided with a masking system which includes stationary and shiftable transverse-edge framing plates. The projected image of a first longitudinal-edge reference line on the copy table supporting the original is brought into register with a corresponding reference line of the masking system. The projection scale is adjusted to cause the format-breadth of the projected image to be at most slightly smaller than the format breadth of the web, but in no event greater. The projected image of the first transverse edge of the original is brought into register with the edge of the stationary framing plate, and then that of the second transverse edge with that of the shiftable framing plate. This registration is effected by sensing infrared-light images of the dark-light transitions associated with the transverse edges of the original. An exposure is performed.

  • Patent number: 4123649
    Abstract: An automatic photographic paper cutter includes a print and order totalizer system which stores information such as the number of prints cut and the number of orders which have been processed by the paper cutter. In one operating mode, the totalizer system counts the number of prints cut in each order. At the end of an order, the number of prints cut in that order is displayed and is maintained on the display until the next order is completed. This allows the operator time to record the number of prints in the previous order while the next order is being cut. In another mode, the totalizer system displays the total number of prints cut and total number of orders since operation of the paper cutter commenced. This information is particularly useful to management since it permits an accurate determination of the performance of both the automatic paper cutter and the particular operator of the cutter.

  • Patent number: 4115001
    Abstract: An apparatus for marking a longitudinal edge of a travelling web has a marking (e.g. notching) station, upstream but adjacent to which is located an abutment. Upstream of the abutment is located aguide arrangement which urges the web transversely of the direction of web travel at an angle skew to the longitudinal centerline of the web, so as to exert on the web a force acting skew to the centerline in the forward direction of web travel and towards the edge to be marked. This urges the edge in part against the abutment to assure that the web travels in predetermined orientation through the marking station.

  • Patent number: 4091403
    Abstract: A film advancing module which cooperates with a basic processing module to duplicate a master microfiche. The film advancing module includes a film drawing station for drawing a continuous strip of diazo microfilm from the basic processing module into the film advancing module, a film cutting station for separating an exposed film segment from the continuous strip of microfilm, a film developing station for drawing the film segment through ammonia vapor to develop it and a film receiving station for collecting the film segment. The supply of ammonia vapor to the film developing station is correlated with the advance of the film segment through the developing station so that essentially all of the ammonia vapor is utilized in the developing process. Any ammonia which might not be utilized is removed from the developing station and neutralized in a tank of citric acid. The developing station includes a plurality of rollers which define a serpentine path of travel for the film segment.

  • Patent number: 4088404
    Abstract: A copying machine, especially a projection printer, wherein a web of photographic paper receives images of successive film frames on an original at an exposure station and the original is monitored by a scanning device which transmits electric signals in response to detection of indicia denoting the last frames of successive orders. The web is formed with first markers which denote successive images thereon and the locations where the web is to be severed to yield discrete prints, and with second markers each of which denotes the last print of an order. A means for applying first and second markers of a first type includes an exposure unit, and a means for applying first and second markers of a second type includes a stamping unit with two punches. Both units are mounted on a carriage which is movable longitudinally and transversely of the web to thereby place the selected unit in an optimum position for the application of markers of the first and second type in dependency on the selected format of prints.

  • Patent number: 4046469
    Abstract: A reciprocating carrier-type photocopy machine having a photoelectric sensor for controlling a copy paper cut-off knife, to conform automatically the size of the copy paper to the size of the original document. A light emitter and photoelectric sensor are mounted beneath a glass platen over which a carrier, which contains the original document, moves for exposing the document to the reproducing mechanism contained beneath. An elongated rectangular mirror is mounted on the bottom surface of the carrier lid for reflecting the emitted light back to the sensor. The original document, when placed in the carrier, blocks the emitted light from being reflected from the mirror to the sensor until the trailing edge of the document passes the emitted light. The reflected light, upon passage of the document, then actuates the photoelectric sensor, which in turn actuates a solenoid of a copy paper cut-off knife to sever the copy paper from its supply roll.
