摘要： A self-processing photographic film unit has a trap member using a nonwoven cloth in order to catch surplus processing solution. This nonwoven cloth is provided with a polymer having carboxyl groups, and a hardening agent for hardening the polymer in order to prevent leakage and change of color to a frame portion of an image forming plane. A nonwoven cloth according to another embodiment includes a fiber of duplex structure which comprises an external layer of a hydrophilic cross linkage polymer and an internal layer of an acrylonitrile type polymer. A further embodiment includes a nonwoven cloth having dimensions of individual gaps or density which are changed stepwise or continuously. This nonwoven cloth is stored in the trap section so that a portion having a small density or large individual gaps is disposed on the inlet side.

摘要： ARE RETAINED TOGETHER SUBSEQUENT TO PROCESSING AND THE LIQUID TRAPPING AND RETAINING SPACES FORMED BY THE SPACER ELEMENT ARE LOCATED WITHIN THE FILM ASSEMBLAGE VERY CLOSE TO THE AREA CONTAINING THE VISIBLE IMAGE. TO NEUTRALIZE EXCESS PROCESSING LIQUID COLLECTED IN THE TRAPPING SPACES AND PREVENT MIGRATION OF A ALKALI INTO THE IMAGE AREA, THE SPACER ITSELF IS AT LEAST COATED WITH CITRIC ACID ON THE SIDE IN CONTACT WITH WHICH THE PROCESSING LIQUID IS SPREAD.

PHOTOGRAPHIC FILM ASSEMBLAGE COMPRISING A PAIR OF SHEET-LIKE ELEMENTS AND A LAYER OF A PHOTOSENSITIVE MATERIAL SANDWICHED BETWEEN THE ELEMENTS INCLUDING AN AREA ADAPTED TO BE EXPOSED AND PROCESSED BY AN AQUEOUS ALKALINE PROCESSING LIQUID SPREAD IN A LAYER BETWEEN THE TWO ELEMENTS TO FORM A VISIBLE TRANSFER IMAGE. THE FILM ASSEMBLAGE INCLUDES A BINDING SHEET SECURED AROUND AND TO THE EXTERIOR OF ADJACENT END SECTIONS OF THE TWO ELEMENTS AND A SPACER FORMED OF A FIBROUS MATERIAL CONTAINED WITHIN THE FILM ASSEMBLAGE BETWEEN THE SHEET-LIKE ELEMENTS AND BINDING SHEET. THE SPACER IS FORMED WITH GAPS WHICH COOPERATE WITH THE ELEMENTS AND BINDING SHEETS TO PROVIDE TRAPPING SPACES FOR COLLECTING AND RETAINING EXCESS PROCESSING LIQUID OVERRUN AS THE END PORTIONS OF THE ELEMENTS ARE MOVED BETWEEN A PAIR OF PRESSURE-APPLYING MEMBERS WHICH SPREAD THE PROCESSING LIQUID.

摘要： Method of manufacturing a succession photographic film units each comprising rectangular photosensitive and second sheets secured in face-to-face relation by a combination mask and binding sheet formed with a rectangular exposure opening, secured to the outer surface of the second sheet and having marginal portions folded around the end and lateral margins of the photosensitive and second sheets and adhered to the lateral and at least one end margin of the photosensitive sheet. The film unit also includes a rupturable container of processing liquid mounted adjacent the trailing edge of the photosensitive sheet and having portions defining a liquid discharge passage coupled with the photosensitive and second sheets so as to direct the liquid contents of the container therebetween; and a trapping element secured between the trailing end marginal portion of the binding sheet and the trailing end portions of the photosensitive and second sheets for collecting and retaining excess processing liquid overrun. During the assembly process, the binding sheet is in the form of an elongate strip which functions as a carrier on which the other components of a succession of film units are mounted as the carrier is moved between and through a succession of work stations at which assembly operations are performed and the components of each film unit are checked for proper assembly. The binding sheet carries the succession of film units through substantially all assembly and inspection steps except for the last two assembly steps in which the lateral edge portions of the binding sheet-which extend transversely of the carrier strip-are folded and adhered to the photosensitive sheet.

摘要： A PHOTOGRAPHIC, SELF-DEVELOPING FILM UNIT COMPRISING A PHOTOSENSITIVE LAYERR INCLUDING SELECTIVELY SENSITIZED SILVERR HALIDE EMULSION HAVING ASSOCIATED THEREWITH DYE IMAGEFORMING MATERIALS, ADAPTED TO BE EXPOSED AND PROCESSED TO PRODUCE A COLOR TRANSFER IMAGE. THE FILM UNIT COMPRISES FIRST AND SECOND RECTANGULAR SHEETS SECURED IN FACETO-FACE RELATION AT THEIR LATERAL AND TRAILLING ENDS MARGINS BY A GENERALLY RECTANGULAR BINDING SHEET INCLUDING A MEDIAL RECTANGULAR OPENING SURROUNDED BY LATERAL AND END MARGINAL PORTIONS. THE BINDING SHEET IS SECURED TO THE OUTER SURFACE OF ONE OF THE SHEETS AND THE LATERAL AND END MARGINAL PORTIONS ARE FOLDED AROUND LATERAL AND TRAILING END EDGES OF THE SHEET AND SECURED TO THE OUTER SURFACES OF THE OTHER SHEET. A CONTAINER OF PROCESSING LIQUID IS ATTACHED TO THE LEADING END OF ONE OF THE SHEETS BY A BINDING STRIP SECURED IN OVERLAPPING RELATION TO THE CONTAINER AND LEADING END MARGIN OF THE SHEET. THE FILM UNIT IS ADAPTED TO BE PROCESSED BY ADVANCING IT, CONTAINER FOREMOST, RELATIVE TO AND BETWEEN A PAIR OF JUXTAPOSED PRESSURE-APPLYING MEMBERS WHICH DISCHARGE THE LIQUID CONTENTS OF THE CONTAINER THEREFROM AND DISTRIBUTE THE PROCESSING LIQUID IN A LAYER BETWEEN THE SHEETS FOR PERMEATION INTO THE PHOTOSENSITIVE LAYER. THE EXTERNAL BINDING SHEET FUNCTIONS TO CONTROL THE THICKNESS OF THE LAYER OF LIQUID AND TO PROVIDE PROCESSING LIQUID AT THE EDGES OF THE EXPOSED AREA SUFFICIENT TO INSURE COMPLETE TRANSFER COLOR IMAGE FORMATION TO THE EDGES OF THE AREA IN WHICH THE VISIBLE IMAGE IS DESIRED. THE BINDING STRIP INCLUDES END SECTIONS EXTENDING A SHORT DISTANCE TOWARD THE TRAILING END OF THE FILM UNIT BEYOND THE LEADING EDGE OF THE OPENING IN THE BINDING SHEET FOR SPACING APART THE PRESSURE-APPLYING MEMBERS TO INSURE SPREADING OF SUFFICIENT PROCESSING LIQUID BETWEEN THE SHEETS IN THIS REGION.

摘要： A PHOTOGRAPHIC FILM UNIT COMPRISING ALL OF THE MATERIALS REQUIRED TO PRODUCE A PHOTOGRAAPHIC PRINT INCLUDING A FIRST ELEMENT WHICH IS A PHOTOSENSITIVE ELEMENT, A SECOND ELEMENT WHICH MAY BE A TRANSPARENT IMAGE-RECEIVING ELEMENT, A BINDING ELEMENT SECURED TO THE EXTERIOR MARGINS OF THE FIRST AND SECOND ELEMENTS ADJACENT THREE SIDES OF THE AREA TO BE EXPOSED AND PROCESSED, AND A CONTAINER OF PROCESSING LIQUID SECURED TO THE ELEMENTS ADJACENT THE REMAINING SIDE OF THE EXPOSURE AREA. THE BINDING ELEMENT SECURES THE FIRST AND SECOND ELEMENTS TO ONE ANOTHER ALONG THREE SIDES OF THE EXPOSURE AREA AND PREFERAABLY ALSO SERVES AS THE MEANS FOR SECURING THE CONTAINER TO THE ELEMENTS ADJACENT THE REMAINING SIDE OF THE EXPOSURE AREA. THE FILM UNIT IS DESIGNED TO BE MAINTAINED INTACT THROUGHOUT AND SUBSEQUENT TO EXPOSURE AND PROCESSING IN WHICH A PROCESSING LIQUID IS DISCHARGED FROM THE CONTAINER AND DISTRIBUTED IN A LAYER BETWEEN THE FIRST AND SECOND ELEMENTS OVER THE EXPOSED AREA TO FORM A TRANSFER IMAGE BETWEEN THE ELEMENTS. THE EXTERNAL BINDING SHEET FUNCTIONS TO CONTROL THE THICKNESS OF THE LAYER OF LIQUID, TO INSURE SUFFICIENT LIQUID AT THE EDGES OF THE EXPOSED AREA TO PROVIDE FOR COMPLETE IMAGE FORMATION AND TO PROVIDE A WHITE BORDER FOR THE FINISHED PRINT.

摘要： A self-processing type photographic film unit having an improved trap structure for collecting surplus processing solution used in developing the unit. The trap structure includes a partition member dividing a pouch-shaped hollow interior formed by a trap cover member into upper and lower chambers and forming a U-shaped flow path which communicates with gas discharging through-holes formed in the upper surface of the trap cover member. First and second spacer members are provided on the lower and upper surfaces of the partition member with the first and second spacer members permitting the U-shaped flow path to pass gas in the unit while catching surplus processing solution.

摘要： A self-processing film unit including an image-recording section, a container for supplying a processing fluid to the image-recording section, and a resiliently flexible carrier permanently attached to the container and separably coupled at its trailing end to the leading end of the image-recording section. The carrier and container are especially adapted to be separated from the image-recording section by deflecting fenders that are spaced in a cooperating camera to engage the lateral edges of the carrier and to bend the carrier with its container into an arcuate path of movement diverging from the imagerecording section. The carrier is notched in both lateral edges at its trailing end, which provides a skirt of reduced transverse dimension that will straighten from the arcuate path and move between the deflecting fenders at approximately the same time the carrier and container are separated from the image-recording section. Thus, the carrier will move itself and the container under the forces of the carrier''s own resiliency to a position where it will not interfere with similar movement of a next successive film unit, and preferably to a generally flat position in a waste-collecting chamber of the camera or a corresponding cartridge in which the film unit was supplied.
