Abstract: A self-processing film unit has an over sheet for covering a surface which is exposed after an image recording sheet with a positive image recorded therein has been peeled off. The over sheet is superimposed on the exposed surface after peeling-off and adheres to the exposed surface to prevent processing liquid remaining on that exposed surface from soiling the hands or clothing of the user.

Abstract: An instant or self-developing transparency film assemblage for producing a 35 mm film transparency ready for mounting in a frame for subsequent viewing in cooperation with a viewer or projector. The film assemblage includes (1) a film chip having an opaque rear surface (2) a first opaque leader for initially covering a front or lens facing surface of the film chip to protect a photosensitive or image-recording layer of the film chip from exposure during the loading of the latter into a camera, (3) a second leader for enabling an operator to pull an exposed film chip between a pair of spread rollers which spread a processing liquid between layers of the film chip to initiate formation of a visible image therein, and (4) a sheet of opaque material which is adapted to be laid across the lens facing surface as the film chip is moved between the spread rollers.

Abstract: A photographic film assemblage includes a pair of sheets bonded together around their edges and being in liquid communication with a sealed rupturable container of film processing liquid. An aperture in one of the sheets is covered by a film chip which, subsequent to exposure, is exposed to the processing liquid through the aperture after the container is ruptured. An image-receiving portion of the film chip is manually separable from the assemblage after suitable developing has occurred. Preferably, the image-receiving portion is a positive color transparency of a 35 MM size ready for immediate placement in a film mount for subsequent use in a viewer or projector.

Abstract: A transparency film assemblage for use with a camera includes a mount with an aperture therethrough. A film frame have a photosensitive layer is bonded to the mount in a position to cover the aperture. Secured to the mount is a foil sheet folded upon itself to form a moisture impermeable envelope. Within said envelope is a foraminous pad impregnated with developing liquid. Following exposure of the film frame the envelope is opened, the pad is laminated to the photosensitive layer of the film frame and the foil sheet is refolded to encompass the mount, pad and film frame in a light impermeable envelope suitable to be ejected from the camera while film developing continues.

Abstract: An image-receiving member of sheet material has a portion on which a positive image is adapted to be formed. A pod of processing liquid is secured to the sheet material outside of the image-forming portion. Each pod is preferably divided into two processing fluid containing portions, such that an advancing roller can contact the flat portion devoid of processing liquid in order to advance the image-receiving sheet without rupturing the pod. The mask defining the area on which a positive image is formed, can be either a continuous sheet having openings at regular intervals, or it can be formed by connector sheets alternately coupled to image-receiving sheets in combination with longitudinal masking strips affixed directly to the image-receiving sheet.

Abstract: A film unit for an instant camera includes a photosensitive sheet connected with a leader sheet. A carrier sheet is partly superposed on the leader sheet and bonded thereto at one end, and a drawer member is bonded to the leader sheet, at one end, near the bonding portion between the carrier sheet and the leader sheet. The other end of the drawer member is projected outside the camera body when the film unit is loaded in the camera. An image receiving sheet to which an image formed on the photosensitive sheet is transferred, is connected to the other end of the carrier sheet. When the projecting end of the drawer member is pulled after exposure, the leading end of the leader sheet is pulled to be inserted between a pair of pressure rolls and to be projected outside the camera body by way of the bonding portion between the drawer member and the leader sheet, with the drawer member being peeled off the leader sheet thereafter.

Abstract: Self-developing photographic film units are disclosed having an IIR sheet cut from an elongate web of material, a second sheet cut from an elongate web of material, and a mask sheet cut from an elongate web of material and spacer means between the IIR sheet and the second sheet. The mask sheet and spacer means serve to seal the IIR sheet and the second sheet together along opposite side margins thereof. A container of processing composition and a trap are disposed at opposite end margins of the film unit.The IIR sheet is strippable between a portion thereof bearing an image after processing and other components of the film unit including a non-image-bearing portion of the IIR sheet overlying the container. Preferably the stripping occurs between photosensitive layers and an image-receiving layer of the IIR sheet. The IIR sheet has a discontinuous slit between the image-bearing portion and the non-image-bearing portion.

Abstract: A photographic film unit of the type comprising two sheets between which a fluid composition is adapted to be spread during processing of a latent image, comprising a fluid trap and gas vent structure for releasing gases expelled from the film unit during the spreading of the processing composition and for receiving excess quantities of the fluid composition, in which a plurality of flow passages are provided in the path of the escaping gas and the advancing fluid composition, and in which a portion of the trap structure comprises a flexible diaphragm forming an expansible chamber having a low impedance to fluid flow relative to the resistance to flow of a plurality of gas vent passages that are provided.

Abstract: A photographic material is processed with a processing liquid by establishing a surface contact between the uppermost layer of the material and a flat porous spreading element impregnated with a low viscosity processing liquid. The impregnation is brought about by providing during or prior to processing for a contact between the spreading element in at least parts thereof with the liquid content of a container for the processing liquid. The spreading element may be flexible or rigid and may consist of woven or knitted fabrics, non-woven webs of endless filaments or staple fibres, non-woven webs of paper fibres, porous plastic foils or porous metal layers.

Abstract: A photographic processing sleeve is provided for receiving and processing a dye donating instant film sheet to produce a photographic print. The sleeve comprises a film retaining sheet that is folded over along its lateral edges to form channels which slidably receive the film sheet, and edge strips, sometimes called side rails, which space the film sheet from the image-receiving sheet. After processing, at least a major portion of the image-receiving sheet, including the finished picture, is adapted to be peeled apart from the rest of the sleeve which can then be discarded.

Abstract: A photographic processing sleeve is provided for receiving and processing a dye donating instant film sheet to produce borderless photographic prints. The sleeve is constructed of first and second sheets coupled together to form a pocket therebetween for receiving the film sheet. One of the sheets includes a central section which carries materials for immobilizing the dyes donated by the film sheet to form a visible picture in the central section. A stripping sheet forms an outermost surface of one face of the sleeve and releasably couples the central section of the first sheet to the remainder of the sleeve so the stripping sheet and the picture in the central section can be stripped away from the remainder of the sleeve.

Abstract: In accordance with the present invention, a photographic film unit suitable for exposure and self-processing includes a substantially rigid mount having a central opening therethrough. A premounted film element is supported in the opening recessed between the mount's front and rear surfaces. A strippable cover sheet extends across the front of the film element to form a space for spreading processing liquid. A film support plug is received in the central opening rearwardly of the film element to inhibit the processing liquid from causing the film element to bow away from the cover sheet when the processing liquid is spread. In a preferred embodiment of the present invention, the film unit further includes a stripping sheet having a mask portion between the film element and the cover sheet, a backing sheet on the rear surface of the mount overlying the central opening, and a hinge portion interconnecting the mask portion and the backing sheet.
