Abstract: A photosensitive material processing device having a processing tank in which is stored a processing solution for processing silver halide photosensitive materials, wherein the processing tank is formed from a crystalline resin and is formed such that, given that a tank volume of the processing tank is V ml and a path length which is a conveying distance from a position at which a silver halide photosensitive material begins to contact the processing solution within the processing tank to a position at which the silver halide photosensitive material is discharged from the processing solution is L cm, a value of V/L is less than or equal to 25. As a result, slidability of the silver halide photosensitive material in the processing tank is increased so that conveyability of the silver halide photosensitive material within the processing tank can be improved.

Abstract: A photosensitive material processing apparatus includes a processing tank and a rack placed in the processing tank. A processing solution is introduced into the interior of the processing tank through the bottom portion of the processing tank. The processing solution introduced from the bottom portion of the processing tank enters a space formed between a bottom turn cover and a bottom turn guide of the rack, and jets from a jetting opening formed in the bottom turn guide toward a transport path for a photosensitive material. Alternatively, the processing solution introduced from the bottom portion of the processing tank enters the space between the bottom turn cover and the bottom turn guide of the rack, passes through a jetting opening formed in the bottom turn guide and a processing solution jetting passage formed in a rack plate, and jets from a jetting opening formed in the rack plate toward the transport path. Accordingly, the processing solution can be agitated effectively.

Abstract: An apparatus for the wet processing of photographic sheet material comprises at least one treatment vessel (12, 12', 12") having upper and lower openings (17, 18), one of the openings constituting a sheet material inlet and the other of the openings constituting a sheet material outlet, the inlet and outlet defining there-between a substantially vertical sheet material path (20) through the vessel. The vessel comprises a pair of rotatable rollers (28, 30) biased towards each other to define a nip (36) there-between through which the sheet material path extends. The apparatus is characterized in that the rollers (28, 30) are axially offset relative to each other; and each roller is in sealing contact along its length, at least between the limits (56) of the nip (36) with a stationary sealing member (38, 39).

Abstract: A color filter is produced through the steps of: forming a layer of a color filter material including a colorant dispersed in a photosensitive resin on a substrate; and pre-baking, exposing and developing the color filter material layer to leave a color filter pattern on the substrate. In the developing step, a developer liquid is applied in the form of a curtain onto the exposed color filter material layer on the substrate, the substrate is allowed to stand in a substantially still state and then the substrate is supplied with an ultrasonic wave projected perpendicularly to the substrate while being in contact with the developer liquid. The ultrasonic wave is preferably uniformized by at least two rotating reflection or diffusion plates before it is projected onto the substrate. As a result, the color filter pattern can be developed with little development irregularity even on a large-size substrate.

The photographic processing apparatus is preferably provided with an index printer and an enveloper to implement effective continuous processing. In the printer section of the photographic processing apparatus, a scanner and a lens are disposed in different positions on a negative film conveying line, and an optical path changeover mirror is provided which is capable of changing the facing direction of the reflecting surface thereof in two directions with respect to the optical axis of one light source lamp.

Abstract: A photosensitive material processing apparatus prevents a developing solution from adhering to a photosensitive material before it is fed into a developing tank, so as not to cause developer streaks. A holding member which supports inlet guide rollers and a holding member which supports outlet guide rollers can independently be taken out of a transport rack for cleaning. The developing solution dripped from the outlet guide rollers does not adhere to the inlet guide rollers. Accordingly, unevenness in development can be prevented, which would occur when the developing solution adheres to the transported photosensitive material before it enters the processing solution.

Abstract: Disclosed is a method for processing a silver halide photographic material, having on one side of a support a hydrophobic polymer layer as the outermost layer and on the side opposite an emulsion layer, by means of an automatic developing apparatus. The apparatus has a drying operation part which is equipped with two or more hot rollers arranged so that the silver halide photographic material may be wrapped partly around each of the hot rollers in turn and the contact between the rollers and the material may alternate between the front surface and the back surface of the photographic material, whereby the moisture in the photographic material evaporates from the surface areas when they are not in contact with the hot rollers. This method results in improvements in the drying characteristics of the photographic material and the transportation characteristics of the automatic developing apparatus.

Abstract: An integrated photographic processing system is equipped with a series of processing stations that are all arranged inside a shared housing. These include an input station for undeveloped, exposed roll film, e.g., miniature film coiled in film magazines. In this input station the inserted roll films are uncoiled and fed into a film conveyance system of an adjacent film processor. In the film processor, the photographic films are developed. At the output of the film processor, a projection printer is arranged for image-by-image exposure onto photographic paper of negatives contained on the developed film. The projection printer is equipped with its own conveyance system for the developed film. Finally, there are also a paper processor for developing the exposed photographic paper, and output stations for the developed film and the developed paper images.

Abstract: Extra printing is made possible during a set of ordinary processing operations such as film development and printing. A film is developed and dried while being fed by a leader attached thereto. After cutting the leader from the film, it is fed to the printing unit to print the images on the film onto photographic paper. A plurality of film stocking units are provided in a path from the film drying unit to the printing unit. Each stocking unit can selectively stock a single film or allow it to pass without stocking. A second film stocking unit can move laterally to change the film track. If a film requiring a long exposure time is present in the printing unit, the subsequent films that have been developed and dried can be stocked in the other film stocking units. Thus, continuous film developing operations are not interrupted.
