Abstract:
A photographic light-sensitive material having a support having a thickness of from 160 to 225 μm is processed with an automatic developing apparatus, in which at least one of rollers of a developing part, a fixing part and a rinsing rack part of the automatic developing apparatus has a surface mainly containing a nonpolar polymer substance and having a center line surface roughness (Ra) of 20 μm or less. By using the automatic developing apparatus, dusts generated in the apparatus can be easily removed with a cleaning film.
Abstract:
A developing apparatus and method is provided in which the use amount of a developing solution can be reduced without deteriorating the accuracy of development. The developing apparatus comprises a new solution tank for storing an unused developing solution and a used solution tank for storing a used developing solution which is withdrawn from a material to be treated. A new solution feeding nozzle extends from the new solution tank, and the tip end of the nozzle faces toward the upper portion of the cup of each developing unit. A used solution feeding nozzle extends from the used solution tank, and the tip end of the nozzle faces toward the upper portion of the cup of each developing unit.
Abstract:
The present invention relates to a photographic processor which includes a circular processing drum and a metering blade assembly provided within the drum. The metering blade assembly is adapted to control or meter an amount of processing solution provided on film to be processed in the film path. The metering blade assembly is adjustable so as to accommodate 35 mm or APS film in the photographic processor. The metering blade assembly is also attached to a support assembly or member which further supports an agitating roller. With the arrangement of the present invention, it is possible to adjust the width of both the agitating roller and the metering blade in accordance with the type of film to be processed in the photographic processor.

Abstract:
A carrier guide can prevent treating solutions from crystallizing thereon and thus can prevent photosensitive materials from clogging and getting damaged and does not require frequent cleaning. The guide surface of the guide provided over the treating tanks is constituted by a water-repellent or ultra-water-repellent layer so that it will repel any treating solution.
Abstract:
When a ring with an exposed dental X-ray film mounted thereon is thrown into a first tank filled with a processing solution, the ring is scooped into a space of a ring-holding portion of a rotating arm through a first opening. As the ring-holding portion is moving in the tank, the ring is pushed by a tilted bottom portion while being held within the space by a release preventing wall and a door so that the ring is also moving together with the ring-holding portion. When the ring-holding portion has fully moved out of the tank, the door is opened and the ring is released from the space into an adjacent tank through a second opening.
Abstract:
High-quality and very rapid processing of light-sensitive materials are accomplished by a wet method with a compact apparatus. A process roller is at least partially submerged in a processing solution in a processing tank. Light-sensitive material is transported as it engages the periperal surface of that part of the process roller which is submerged in the processing solution. The absolute value of the peripheral speed of process roller is greater than the absolute value of the transport speed of the light-sensitive material. The roller is rotated at a speed of at least 75 rpm. With the invention, the light-sensitive material can be processed in a very rapid and yet satisfactory manner since the processing solution is rapidly replaced by fresh solution at the surface of the light-sensitive material. In addition, only a small amount of the processing solution need be used, which contributes to a reduction in the size of the processing apparatus.
Abstract:
A compact, simple, fully automatic table-top plate processor for developing offset plates which are inserted horizontally in the front and ejected horizontally from the rear using paired transport rollers and brush rollers training the plate at the exit and thus provides a finished press-ready or storable plate in one cycle. Top rollers fit into essentially vertical slots and have keyed bearings to prevent rotation. The roller drive motor is of such a speed as to provide the proper dwell time prior to the plate being brushed on both sides. The processor provides automatic developing of the plate in an essentially horizontal feed-through operation permitting use on the top of an existing table surface and requiring a minimum of space. By combining the gum into the developer solution the need for several stages (develop, rinse, condition, gum, etc.) is eliminated and this one step machine provides a unique compactness of design.
Abstract:
Apparatus for automatically treating photosensitive paper after exposure in an automatic camera comprises four treatment tanks each having its own dipping mechanism, and three transfer mechanisms between the tanks. Each dipping mechanism and each transfer mechanism comprises a pair of grooves in which the paper can slide, and one or two motor-driven teeth to push the paper along the grooves. By use of separate dipping mechanisms and separate transfer mechanisms, only the paper travels from tank to tank, minimizing transfer of fluid from one tank to the next.
