Abstract: An automatic photographic developing apparatus for photosensitive materials includes a number of processing baths which are filled with processing solutions of different types for processing silver halide coated photosensitive materials. A same number of solution tanks communicated with the respective processing baths are provided for supplying the processing solutions, produced by dissolving solid agents, to the respective processing baths. Each of the solution tanks is protected with an openable cover and is provided with a guide along which the respective solid agents can be loaded into the respective solution tanks for dissolution as the solid agents run down by their own weight. The guide is pivotably mounted for movement between a guiding position and a non-guiding position and is urged by a return spring so that the guide can automatically return to the guiding position.

Abstract: An automatic photosensitive material developing machine supplies a solid processing solution to be dissolved according to consumption of processing solution for a silver halide photosensitive material to be treated. The developing machine includes a solid processing solution supplying section for supplying the solid processing solution from a solid processing solution cartridge containing the solid processing solution, and a solid processing solution transferring section for receiving the solid processing solution supplied by the solid processing solution supplying section in a bucket, and for transferring the bucket upward.

Abstract: An automatic photographic developing apparatus for photosensitive materials includes a number of processing baths which are filled with processing solutions of different types for processing silver halide coated photosensitive materials. A same number of solution tanks communicated with the respective processing baths are provided for supplying the processing solutions, produced by dissolving solid agents, to the respective processing baths. A level sensor is installed in each of the solution tanks which monitors the level of the processing solution in the respective solution tanks. A plurality of shield members are provided, each shield member surrounding and protecting a respective one of the level sensors, and each shield member being detachably mounted to its respective level sensor. Each of the shield members includes a plurality of split members which are separable from each other and which are connectable to each other to surround the respective level sensor.

Abstract: In an apparatus for supplying a solid processing agent to a processing tank of a photographic material processing apparatus, there is provide a put-back mechanism for putting a solid processing agent back into an accommodation container when the accommodation container is moved from a operating position to a maintenance position on which the accommodation container can be replaced with a new one.

Abstract: Disclosed is a trimming device for use with a photographic printer having a fixed window mask unchangeable in size and a variable window mask having a movable window frame for changing a window size. Each window of the fixed window mask and the variable window mask is shaped symmetrically in the optical axis of exposure light so that exposure light is projected through smaller window among the fixed window mask and the variable window mask. There is provided a film guide plate for guiding a film frame to be printed into exposure light. The film guide plate is adapted to allow a film frame to move in X and Y directions, and the movable window frame is also adapted to change a window size in the both X and Y direction, Symmetrically in the optical axis of exposure light.

Abstract: An automatic photographic paper processing apparatus wherein between an exposure unit (2) for printing a photographic paper and a transferring means (9) for discharging an exposed photographic paper a discharge accumulating unit (A2) for accumulating temporarily the exposed photographic paper is provided, so that when an amount of the photographic paper accumulated at the discharge accumulating unit (A2) is decreased the photographic paper is cut by operating a cutter unit (20) arranged at the downstream of the exposure unit (2) and then the transferring speed at the transferring means (9) is increased.An automatic photographic paper processing apparatus wherein a paper accumulating unit (102) for accumulating temporarily sensitive photographic materials fed from an exposure unit (2) is provided at a position preceding a developing processing unit (103) consisting of a plurality of processing tanks (131, 132, 133, 134).

Abstract: A photographic printing method include the steps of entering information into a storage medium as to location of each of a plurality of image frames on a negative film to be printed, entering data into said storage medium as to the desired print position of each of a selected number of said frames, and controlling a negative film transporting means and a printing paper moving means based on said information and said data to independently locate each of said selected number on said paper.

Abstract: Disclosed herein is a photographic printing apparatus including at least one of image-rotating lenses 25 and 26 which enables the production of prints of the same size from photographic films both of full size and half size by a 45-degree rotation of said image-rotating lenses 25 and 26.

Abstract: A photographic printer comprises negative film supply, transport, and printing exposure sections which have mutually interchangeable supply and transport mechanisms for supplying and transporting 135-size films and disc films to the printing exposure section. The supply and transport mechanism for disc films has a section containing a plurality of disc films which are transported automatically to the printing section through a transporting section of the disc film supply and transport mechanism. The negative film supply section also has a delivery section for 135-size cut films and the delivery section for disc films, which are mutually interchangeable to supply either 135-size cut films or disc films.

Abstract: Disclosed herein is a photographic paper rolling apparatus wherein at least three rollers 8, 9 and 10 are pressed against the outer periphery of a roll-up shaft 3 for the photographic paper 40, the photographic paper 40 is rolled round the roll-up shaft 3 while being held between the rollers 8, 9, 10 and the roll-up shaft 3, and the rollers 8, 9 and 10 are separated from the rolled-up paper and withdrawn from the roll-up shaft 3 when the photographic paper 40 has been rolled up to some extent and the outer diameter of the roll of paper becomes large.
