摘要： Apparatus for convoluting exposed and copied photographic films on the cores of takeup reels has an advancing mechanism which transports successive films along a given path so that the leaders of successive films can be engaged by the gripper of a pivotable arm serving to transfer the leader of the film in the path toward the peripheral surface of the core of an empty takeup reel. The reel has no flanges or is provided with a single flange carrying or adjacent a fixedly mounted or movable protuberance which defines with the peripheral surface of the core a gap for the leader of the film. Once the leader has entered the gap and the takeup reel is set in rotary motion, the film is wound onto the protuberance and is thus affixed to the core. The length of the protuberance is less than the axial length of the core but exceeds one-fourth of such axial length.

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： A copying machine admits a web of freshly exposed photographic paper directly into a cassette whose core engages and convolutes the web therearound. The progress of engagement between the leader of the web and the core is monitored by comparing the peripheral speed of the core with the peripheral speed of a rotor forming part of an advancing roll for the web and receiving torque from a variable-speed motor which also drives the core. The peripheral speed of the rotor increases when the leader of the web is adequately attached to the core, and this is detected by a circuit having first and second photoelectronic monitoring devices which respectively monitor the peripheral speeds of the rotor and the core. The signals which are generated by the monitoring devices are processed, and the processed signals are used to change the speed of the variable-speed motor, to deactivate a catcher mechanism which directs the leader of the web toward the core and assists in the establishment of adequate engagement between the leader and the core, to change the supply of energy to the motor as the diameter of convoluted web on the core increases, and/or to actuate an alarm device when the completion of attachment of the leader to the core is unduly delayed.

摘要： A method of printing regular photographic prints on a strip of paper along with index prints--that is, prints with images that are smaller than those in the regular prints--from series of negatives on rolls of film. The smaller images are projected next to and one after another along the strip to produce an index print as wide as the strip. The regular prints and the index prints are printed at different points along the strip. The results of area-by-area measurements of the negatives obtained while the regular prints are being printed are exploited to control light quantities while the index prints are being printed. The distance the strip of paper advances from one printing point to the other is regulated to ensure that paper is advanced to the index print printing point once the last negative in a series has been projected onto the strip until the trailing edge of the last print arrives at the margin of the exposure area in the index print printing point. Further printing procedures are discontinued at the regular print printing point until the trailing end of a length of paper that is reserved for the index print associated with that series of negatives, and that must accordingly not be exposed to light, has crossed the edge of the exposure opening near the index print printing point.

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 filmstrip has a longitudinally extending row of image areas and a row of perforations along each longitudinal margin. The image areas and perforations have no fixed positional relationship. The filmstrip is conveyed lengthwise from a scanning station to an operating station. A procedure involving the filmstrip is performed at the operating station when an image area is present at such station. To establish the arrival of an image area at the operating station, the filmstrip is photoelectrically scanned at the scanning station to locate the leading edge of the image area. The leading edge is conveyed from a preselected location, which may or may not be the scanning station, to the oeprating station along a path of fixed length. The length of the path is expressed in terms of the spacing between neighboring perforations of a row and the arrival of the leading edge at the operating station is established by counting perforations as the filmstrip travels. Fractions of the perforation spacing, which may arise if the leading edge is located between two perforations or if the path length is not an integral multiple of the perforation spacing, are measured by counting the steps performed by a stepping motor which drives the filmstrip or by counting the revolutions of rollers which engage the filmstrip.

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： 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： A film has a series of exposed and developed negatives. Each negative is scanned at a multiplicity of regions, and the densities of each region in the three primary colors are measured. A blue/red density differential is derived for each region by subtracting the red density of a respective region from its blue density. The neutral density of each region is calculated, and every region is assigned a coordinate on a plot of blue/red density differential versus neutral density. According to one embodiment, the blue/red density differential for each region having a neutral density equal to or greater than a limiting value is then subtracted from the blue/red density differential given by a characteristic curve for the film. The differences obtained in this manner are analyzed, at least for selected negatives, and the minimum difference for each selected negative is determined. The region corresponding to the minimum difference is that region of a negative having the maximum blue density. The blue/red density differential for the region of maximum blue density is compared with a pair of reference values derived from respective reference curves representing blue/red density differential as a function of neutral density. Based on the results of this comparison, each selected negative is classified as to whether it was exposed by artificial light or natural light, and is assigned an appropriate color correction factor for copying. Another embodiment is employed if the characteristic curve is found to lie near one of the reference curves. Here, the steps of subtracting blue/red density differentials and analyzing the resulting differences are omitted, and all negatives of the film are immediately classified as having been exposed by artificial light.
