摘要:
A light-tight, temperature controlled system, controlled by a controller, for processing a photographic film housed in a film cartridge detachably secured upon a spool caddy having a plurality of processing spools mounted thereon, includes: means for rotating a spiral shaped wall about a rotational axis, the spool caddy being detachably mounted upon the rotating means in a predetermined positional alignment; means for combining an emulsion side of the film with processing webs from the processing spools along the spiral shaped wall for preset dwell times by sequentially in a preset order removing and replacing each of the processing spools and the film cartridge from and to the spool caddy, unwinding and rewinding the processing webs from and to the processing spools, and unwinding and rewinding the film from and to the film cartridge; and means for securing the processing spools and the film cartridge along a channel formed by the spiral shaped wall while the emulsion side of the film is being sequentially combined with the processing webs.
摘要:
A development processing apparatus including a pair of rollers for laminating a silver halide photosensitive material on which an image has been exposed and a processing sheet containing chemicals for forming an image on the silver halide photosensitive material; a heating plate having a curved heating surface for subjecting the silver halide photosensitive material to development processing by heating the silver halide photosensitive material and the processing sheet laminated by the pair of rollers; a transport belt for transporting the silver halide photosensitive material and the processing sheet laminated by the pair of rollers along the heating surface of the heating plate to allow the heating plate to effect the development processing; and a separation roller for separating the silver halide photosensitive material and the processing sheet after completion of the development processing by the heating plate. Accordingly, since processing solutions such as a developer and a fixer are not used for the development of the photosensitive material, the efficiency in maintaining the apparatus can be improved.

An image recording device in which an image is exposed onto a photosensitive material, and an image forming solvent is applied thereto, and an image receiving material is superposed thereon, and then heat development transfer is carried out so as to obtain an image on the image receiving material, comprising: a fixed stage which holds the photosensitive material; an application unit which applies the image forming solvent to the photosensitive material; a superposing unit which superposes the image receiving material on the photosensitive material; a connecting tool which connects the application unit and the superposing unit such that the units are moved integrally with one of the units in front of the other; and a squeeze roller which is disposed between the application unit and the superposing unit and is moved in accordance with the integral movement thereof, wherein as the application unit and the superposing unit are moved such that the application unit is positioned in front of the superposing unit, the image forming solvent is applied to the photosensitive material by the application unit, the applied photosensitive material is squeezed by the squeeze roller, and the image receiving material is superposed by the superposing unit on the squeezed photosensitive material. Since the stage is used in common for application and superposition in this way, the image recording device can be made more compact.

Processing apparatus for image-wise exposed light-sensitive sheets of the DTR-type, which comprises a trough (11) for processing liquid, a sloping entry guide plate (17) for guiding a sheet towards its deepest point, a pair of outlet rollers (16) for pulling a sheet at a uniform speed through the apparatus and for squeezing liquid from it and replenishing means for keeping a processing liquid in the trough at a controlled level, which apparatus is provided with a floating cover (25) arranged for floating on the free surface of the processing liquid, and means for maintaining between the rear edge of the floating cover and the rear end of the trough a space (41) sufficient to allow unhindered passage of a processed sheet towards the outlet rollers.
摘要:
An image reproducing device in which a photosensitive film cartidge, a transfer sheet cassette and a developer pod receptacle are mounted separately, and a peel-apart type film is used. The kinds of photosensitive film, transfer film and pod are detected to prevent an incorrect combination and to inhibit the operation of the device. In other embodiments, some of the elements are mounted together. The elements are marked with a code which is sensed.
摘要:
An image forming apparatus superposes an image receiving sheet on a light receiving sheet and presses them together such that a selectively hardened image formed on the light receiving sheet is transferred to the image receiving sheet to form a visible image. The used portion of the light receiving sheet is wound up around a take-up shaft after separated from the image receiving sheet by means of a separator. A retracting mechanism is provided to the separator such that the separator is retracted from the normal position on the travel path of the light receiving sheet when the front end of the light receiving sheet is initially wound around the take-up shaft.

A photograph-producing apparatus used for rapidly obtaining a portrait photograph of a person for such purposes as pasting on a certification. When a heat development photosensitive material is sent from a receiving portion to a photographic exposure portion in which an image is exposed thereon, frame exposure is performed around the image to form a white portion around the image serving as a final product. After the image has been exposed on the photosensitive material, a solvent for forming the image is applied to the photosensitive material and then adhered to an image-receiving material so that an image or picture is transferred to the image-receiving material which then serves as the product.
摘要:
An image recording apparatus which forms an image on an image receiving medium by transferring an image recorded on a heat-developable photosensitive medium in the presence of an image forming solvent, the apparatus having an application roller which is partly immersed in the solvent and which functions, while rotating, to apply this solvent to the heat-developable medium or the image receiving medium. Grooves are provided on the application roller in the vicinity of the axial ends thereof. The image forming solvent is thereby uniformly attached to the outer periphery of the application roller, and this solvent is then uniformly applied to the heat-development medium or the image receiving medium.
