摘要： A filmstrip containing a series of images is conveyed along a path which passes by a copying station and a scanning station. The filmstrip is advanced in steps using transporting rolls and a narrow segment of the filmstrip is scanned at the scanning station after every step. A first set of measurements obtained upon scanning of the filmstrip is used to calculate the amounts of light and the exposure times required to properly reproduce the images. A second set of measurements is used to detect characteristic regions of the filmstrip having abrupt changes in density. The positions of the characteristic regions along the filmstrip are established by a counter which counts the steps undergone by the filmstrip and the measurement or measurements corresponding to each characteristic region are stored together with the respective position. The positions of the characteristic regions and the second set of measurements are used to calculate the positions of the images along the filmstrip. After the filmstrip has been completely scanned, the filmstrip is conveyed along the path once more. During the second trip along the path, the filmstrip is scanned again while the distance traveled by the filmstrip is measured by the counter. Upon detection of a characteristic region, the position of such region along the filmstrip as measured by the counter during the second trip is compared with the stored position obtained during the first trip. If the positions are different, the counter is changed to match the stored position. This compensates for slip between the filmstrip and the transporting rolls thereby allowing the images to be accurately positioned in the copying station for reproduction as the filmstrip travels along the path for the second time.

摘要： An exposed and developed photographic filmstrip having a series of image areas is conveyed along a path and is photoelectrically scanned at a first location of the path to detect regions characterized by marked density jumps. A signal is generated in response to detection of each such characteristic region and a first distance measuring device disposed near the first location assigns a first distance reading to each characteristic region upon detection thereof. The first distance readings are representative of the positions of the characteristic regions longitudinally of the filmstrip. Each signal is stored together with the respective first distance reading. The stored signals and first distance readings are used to calculate the positions of the image areas longitudinally of the filmstrip, and the calculated positions are likewise stored. From the first location, the filmstrip travels to a second location of the path where a notch is punched in the filmstrip adjacent to each image area. Immediately upstream of the second location, the filmstrip is photoelectrically scanned for a second time to again detect the characteristic regions.

摘要： Successive frames of an exposed and developed customer film are monitored during transport of the film in a first direction, and the information which is gathered during monitoring of discrete frames as well as of the entire film is stored in the memory of a microprocessor. The direction of travel of the film is then reversed and successive or selected frames of the film are copied during intervals between successive stepwise advances of the film in the second direction. Copying light which is used for the making of reproductions of images of the film frames is also used for illumination of film frames during monitoring. A mirror is provided to reflect light to the monitoring unit during travel of the film in the first direction, and such mirror is retracted preparatory to copying which starts with the last monitored frame and proceeds toward the first monitored frame of the film. The film is converted into a growing roll during monitoring of its frames.

摘要： Each original in a strip of such originals is scanned during longitudinal travel of the strip using a scanning spot which repeatedly traverses a stationary scan line extending transverse to the direction of strip travel. The scanning spot has a scanning speed such that the scanning spot travels from one to the other end of the stationary scan line in a time less than the time in which the strip travels a distance equal to the breadth of the scan line. The scanning spot which repeatedly traverses the scan line is generated using a light shield having a slit which delimits the scan line and a rotating disk having equiangularly spaced apertures which move through a stationary light beam passing through the moving strip of originals.

摘要： Apparatus for processing signals which are transmitted by the transducers of photoelectric cells scanning discrete marginal fields of square or rectangular film frames on a web of photographic film has relay-actuated switches which can connect the transducers of selected cells to each other and with the foreground and background inputs of a signal receiving circuit which is connected to the exposure controls of a copying machine or to a data carrier. The frames are examined by an attendant who energizes selected relays or several relays at a time to thereby cause the switches to transmit to the two inputs appropriate signals denoting the density and/or other characteristics of corresponding groups of neighboring marginal fields, depending upon whether the frame which is being inspected by attendant has been exposed in normal orientation, at right angles to normal orientation or upside down.

摘要： A photographic copying machine wherein the images of successive frames on a long roll of spliced-together exposed and developed customer films are copied while successive films are advanced stepwise from a supply reel on a first driven mandrel toward and is convoluted on a takeup reel on a second driven mandrel. The copying machine employs a third mandrel which can support a fresh roll in the plane of the roll on the first mandrel, and a fourth mandrel which can support an empty takeup reel in the plane of the rotating takeup reel. The leader of the fresh roll is located adjacent the film path ahead of the copying station and is automatically advanced into the range of an automatic attaching mechanism when the trailing end of the expiring roll has advanced beyond the copying station. The attaching mechanism secures the leader of the fresh roll to the core of the empty takeup reel, and the machine is then ready to make copies of frames forming part of the fresh roll. The filled takeup reel on the second mandrel is replaced with an empty takeup reel and a fresh roll is placed onto the first mandrel while the machine copies the frames of the roll which is supported by the third mandrel and is convoluted on the takeup reel on the fourth mandrel.

摘要： Light from a light source is transmitted through an original at a scanning station to a light detector. A rotating scanning disk located in the path of this light is provided with equiangularly spaced radial scanning slots. A light-blocking plate located between the light source and the scanning disk defines a scanning slot extending transverse to the transport direction of the original. Light passing through both the original and the transverse scanning slot is projected as a slot image onto the surface of the scanning disk. The radial slots and the transverse slot cooperate to define a scanning spot which sweeps across the original, and thereby performs one line-scan operation, as one radial slot sweeps across the slot image on the scanning disk. The angular span between adjoining radial slot is greater than that of the slot image so that, during intermediate intervals between successive line-scan operations, light transmitted through the original does not reach the light detector. During the intermediate time intervals, reference light from the light source is directed onto the light detector along a reference light path not passing through the original. An evaluating circuit receives both the signal produced by the light detector during a line-scan operation and the signal produced during the preceding or subsequent intermediate time interval, and in dependence upon the values of both signals produces a signal whose value indicates the density of the extreme-density scanned spot on the scanned original.

摘要： Apparatus for the determination of light transmissivity of film frames preparatory to the making of prints in a copying machine has a plate-like locating device for successive film frames, a light source at one side of the locating device, a group of photosensitive signal-generating elements at the other side of the locating device, and a diaphragm which is interposed between the locating device and photosensitive elements and has a hollow truncated pyramid, plate-like partitions and tubular components which confine light passing through the film frame on the locating device in such a way that a centrally located photosensitive element receives light from the entire film frame and all of the light which has passed through the central field of the frame, whereas each of the other photosensitive elements receives only that light which has passed through a single one of four L-shaped peripheral fields surrounding the central field of the frame. Light which reaches the centrally located element passes through the pyramid as well as around the pyramid. On the other hand, light which reaches the other photosensitive elements passes from the corresponding peripheral fields and thereupon through the tubular components of the diaphragm. Consequently, the signal which is transmitted by the centrally located element is indicative of transmissivity of the entire frame, and the signals transmitted by the other elements are indicative solely of transmissivity of the respective peripheral frames.

摘要： A series of exposed and developed film strips having various lengths are spliced end-to-end for copying. The resulting band passes through a density measuring station in which the densities of the negatives are measured in the three primary colors and next through a magazine of variable capacity in which a portion of the band accumulates before entering a negative copying station including an exposure control device which regulates the exposures of the negatives on the measured basis of the density values. To insure that values derived from a selected strip are transferred to the exposure control unit when the strip enters the copying station, the splice immediately downstream of the selected strip is arrested in the density measuring station. The band continues to be drawn through the copying station so that the portion which has accumulated in the magazine is fully withdrawn. The portion of the band between the arrested splice and a splice sensor in the copying station has a known length. The arrested junction is now released and a length measuring device begins to measure the length of the portion travelling through the copying station. If the sensor detects a splice when the measured length equals the known length, this splice is the previously arrested splice.
