摘要： A cassette for winding and unwinding rolls of photographic paper has a rotatable shaft which traverses the cassette. A spool for supporting a roll of photographic paper is mounted on and circumscribes the shaft. The shaft is supported by a pair of opposite sidewalls of the cassette. Bearing rings are mounted in each of the sidewalls and the shaft carries a pair of bearing disks which respectively mate with the bearing rings. The bearing rings and disks are designed such that they form a braking system for the shaft. An overrunning clutch is arranged between the shaft and each of the bearing disks. The overrunning clutches are oriented so that the shaft rotates freely when photographic paper is being wound onto the spool. During unwinding of photographic paper from the spool, the clutches engage and the braking system for the shaft becomes operative.

摘要： Apparatus for making prints of exposed and developed film frames on discrete sheets of photographic paper and for developing the sheets has a copying station for successive exposed and developed film frames and a printing station where a discrete sheet of photographic paper receives an image of the frame at the copying station. A platform at the printing station carries a turntable which can change (when necessary) the orientation of a sheet, e.g., through 90.degree., to thus properly position a larger or smaller sheet for reception of the image. The turntable can receive sheets which are severed from different webs of unexposed photographic material, and each such web has a different width. The turntable can attract a sheet by suction during turning and/or during exposure. Such turntable can cooperate with one or more conveyors to maintain a sheet at the printing station in a predetermined plane during imaging of a film frame.

摘要： An exposed and developed filmstrip and band of similar length are connected edge-to-edge. An address for each negative of the filmstrip is imprinted on the band in the form of a bar code adjacent to the respective negative. The negatives are scanned and exposure values are calculated for the negatives from the resulting data. The exposure values are used to make proofs, and the exposure values for each negative are then stored in a memory under the corresponding address. When an order for final copies of a particular negative is subsequently received, the address of the negative is read from the band and used to retrieve the respective exposure values from the memory. The final copies are thereupon made based upon the retrieved exposure values.

摘要： A strip of exposed and developed film has a series of exposures and corresponding exposure identification numbers. The strip is conveyed through a scanning station on its way to a printing station. The exposures and identification numbers are scanned in the scanning station to produce output signals indicative of density changes. The signals are processed to generate groups of data which are combined into a data set. Each group includes the position of a respective exposure on the strip, the identification number for the exposure and the position of the identification number on the strip. Film transport is carried out in such a manner that scanning of the strip and processing of the resulting signals are completed before arrival of the strip at the printing station. A control unit uses the data set to position the exposures in the printing station and to print the exposures. The control unit also uses the data set to mark a copy of an exposure with the identification number of the exposure.

摘要： Light containing blue, green and red radiation is passed through a colored original which is to be printed on color copy material. The transmitted light is spread out into a color spectrum which extends across a first wavelength range generally corresponding to the blue portion of the spectrum, a second wavelength range generally corresponding to the green portion of the spectrum and a third wavelength range generally corresponding to the red portion of the spectrum. The intensity of the transmitted light is measured throughout the spectrum and average of the resulting raw intensities are taken oer each of a series of wavelength intervals which are much shorter than the first, second and third ranges. The copy material has a gamma value for each wavelength interval and such gamma value represents the spectral sensitivity of the copy material in the corresponding interval. The average intensity for each wavelength interval is multiplied by the respective gamma value to yield a corrected intensity. The corrected intensities for each wavelength range are summed to generate first, second and third sums corresponding to the first, second and third ranges and respectively representing the blue, green and red densities of the original. The first, second and third sums are used to calculate the respective amounts of blue, green and red light required to print the original with a neutral gray density.

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： A copier is designed to copy negatives of different sizes onto copying material of different widths. The negatives and copying material are supplied from rolls. The copier includes the following manually controlled components: (i) a set of interchangeable film guides which are used at a scanning station and are slotted to permit photoelectric scanning of the negatives; (ii) a set of interchangeable masks for masking the negatives during copying; (iii) a set of light shafts for illuminating the negatives during copying; and (iv) a movable guide unit for the copying material. A computer associated with the copier is arranged to receive signals indicative of the following manually obtained settings: (a) the type of dimensions of the particular film guide installed in the copier; (b) the type of dimensions of the particular film mask installed in the copier; (c) the type of light shaft installed in the copier or the cross-sectional area of the outlet aperture for the light beam; and (d) the position of the guide unit for the copying material which is related to the width of the latter. The copier further includes a motorized mask for regulating the length of copying material to be exposed, and an adjustable objective having motorized lens elements. The motors for the motorized mask and the lens elements are controlled by the computer. The computer has a memory which stores all possible combinations of settings for the manually controlled and motorized components. When the size of a negative to be copied changes, these components are adjusted for the new size. The manually controlled components are adjusted first. Prior to adjustment of the motorized components, the computer checks the settings of the manually controlled components against the stored combinations of settings to ascertain whether the particular combination of manual settings is possible.
