摘要： An automatic photographic paper cutter cuts photographic prints from a strip of photographic paper which bears cut indicia indicating the locations of desired paper cuts. An indicia sensor is positioned in fixed relationship with respect to the paer cutter knife assembly at a distance less than the shortest length of print to be cut. The paper cutter derives and stores a feed-after-sense signal, which represents the length the paper strip must be fed after a cut indicium is sensed in order for the strip to be cut at the desired cut location represented by that cut indicum. During automatic operation of the paper cutter, the photographic paper strip is advanced until a cut indicium is sensed, is advanced by an additional distance determined by the feed-after-sense signal, is stopped, and is cut at the desired cut location.

摘要： An automatic photographic paper cutter cuts photographic prints from a roll of photographic paper which bears indicia indicating the location of desired cuts. The automatic photographic paper cutter has an improved indicia sensing system which includes a plurality of indicia sensors, each positioned to sense indicia on a different portion of the photographic paper. Prior to automatic operation of the paper cutter, an indicia bearing portion of the photographic paper is oscillated back and forth past the plurality of the indicia sensors. One of the sensors which provides an acceptable output signal is selected, and subsequent operation of the photographic paper cutter is controlled in response to signals from the selected sensor.

摘要： A photographic print stacking device is positioned proximate the discharge end of the conveyor system which conveys photographic prints from a photographic print cutter. The print stacking device includes upper and lower print receiving elements, which are yieldably urged toward one another. The lower print receiving element is movable generally downward and away from the upper print receiving element as the prints are deposited on the lower print receiving element. The conveyor system delivers the prints to the stacking device with sufficient force to carry the prints between the upper and lower print receiving elements until their front edges engage a stop element. As a result, the rear edges of the prints are all substantially in alignment at a location proximate the discharge end of the conveyor system. The stop element preferably is releasably latched in an operative upstanding position and may be moved out of the way by the operator when removing an accumulated stack of prints.

摘要： A photographic slide mounter cuts photographic film transparencies from a photographic film web and inserts the transparencies into slide frames. The slide mounter includes a slide advance device which advances a slide frame to a position where the slide frame is flexed to provide an insertion opening. The film web is advanced into the insertion opening until a leading end of the film is partially inserted into the slide frame. A knife severs a transparency at a position outside of the slide frame. The slide frame with the partially inserted transparency is then advanced along a track away from the film severing and insertion station. The film transparency is engaged and fully inserted into the slide frame as the slide frame and the transparency are fed along the track. A film curl accommodator bends the slide frame by an amount sufficient to match the curl or bow of the transparency as the transparency is being fully inserted into the slide frame.

摘要： A photographic packaging system includes a monitoring system which permits the operator to compare frames of the film negative with prints which are being cut so as to assure that the proper prints will be packaged with the corresponding film negatives. The monitoring system includes a television camera and display and a view splitter which is positioned between the television camera and the film negatives. The view splitter splits the field of view of the television camera so that the camera views two separate frames.

摘要： A knife assembly capable of cutting photographic strip material with high accuracy at extremely high speeds includes a base, a stationary blade, a source of rotary power, a crank shaft, a spring-wrap clutch mechanism, first and second linear drive shafts, first and second adjustable linear bearings, and a movable blade. The spring-wrap clutch is mounted on the crank shaft for selectively imparting rotary power to the crank shaft, and the first and second linear drive shafts are connected to the drive shaft. The movable blade is connected between the ends of the first and second linear drive shafts.

摘要： A photographic print sorter has a series of print slides along which the photographic prints are driven by drive rollers. Deflectors which are movable into the flow path are positioned between the print slides selectively deflect the prints into good, reject and remake print trays. Each print slide has a recess below each drive roller. The radius of each drive roller is betwen about 0.005 inches and about 0.045 inches greater than the distance from the axis of the drive shaft to the transport plane defined by the top surface of the print slide. This creates an interference fit between the drive rollers and the photographic print as the print is driven over the print slide.
