摘要： PROBLEM TO BE SOLVED: To prevent the generation of stain having adverse effect on image quality even when a large quantity of silver is eluted by the development of a photosensitive material containing a large quantity of silver. SOLUTION: In a photosensitive material processing device for developing a photographic film containing silver of >=10 g/m2, one composed of a material easily impregnated with silver particle, eluted in the developer in a developing vessel from the photographic film and reduced, and having the surface having >=50 deg. hardness is used as a transporting roller for transporting the photographic film and arranged in the developing vessel. The stain of an industrial X-ray film is prevented by recovering the silver estimated to be eluted in a large quantity by a paper wound phenol roller (slashed ones in the transporting rollers 22) to keep the silver into the insidemore than on the surface in the case of developing the industrial X-ray film.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of such a stain which adversely affects image quality even if there is elution of a large amount of silver by disposing a metallic plate in a position where the metallic plate is immersed into a developer in a developing tank made of a synthetic resin. SOLUTION: A processing liquid processing section has the developing tank 14 where the developer is stored, a fixing tank where a fixer is stored and a washing tank where washing water is stored. The respective processing tanks are integrally molded of synthetic resins, such as PPE. A box-like object (stainless steel plate 14S) assembled of stainless steel plates is disposed in such a manner that the metallic (stainless steel) plate is arranged along inside walls (inclusive of a bottom plate part) in the developing tank 14. When an exposed X-ray film is transported while the X-ray film is immersed in the developer stored in the developing tank 14, the X-ray film is developed. The silver eluted as silver ions in the developer and reduced by a developing agent deposits on the stainless steel plate 14S and the concentration of the silver ions eluted in the developer can be lowered.

摘要： PROBLEM TO BE SOLVED: To prevent respective chemicals from mixing with each other at delivery ports when supply of a processing supply liquid is stopped, in the event that the plurality of chemicals are delivered at positions relatively near to each other and that they are mixed into a processing liquid to produce the processing supply liquid. SOLUTION: Because a thin-walled tapered tongue member 114 is formed in one body with a delivery opening part 106 of each of four pipe conduits 110 in a pipe assembly 110, liquid cut-off is made quicker at the delivery opening part 106 and therefore neighboring liquids are inhibited from mixing with each other. Thus, phenomena, such as deposition and solidification, caused by liquid mixing at the delivery opening part 106 and needing future maintenance, are prevented and maintainability can be improved.

摘要： PURPOSE:To obtain the automatic developing machine capable of maintaining the water content of a photosensitive material and its drying characteristics both constant. CONSTITUTION:The rinsing water of a rinsing bath 18 is controlled to a prescribed temperature by temperature control means, such as a recycling pump 30, a heater 34, and the like, thus permitting the water content of the photosensitive material F drawn toward a squeezing zone 46 to be kept constant, and rubber rollers 42 of >=61 deg. hardness and rubber rollers 44 of 30 deg.-60 deg. hardness are arranged in the squeezing zone 46, thus permitting a squeezing capacity to be enhanced by combination of the hard and soft rubbers. Since the diffusivity of heat of the rubber rollers 42, 44 are small as 0.1mm /sec, the photosensitive material F is not lowered in temperature and the water content can be kept constant, thus permitting the photosensitive material F to be uniformly dried without causing uneven drying.

摘要： PURPOSE:To prevent the unequal driving from a drive shaft to respective loads by a change in the loads between plural sets of driving gears and driven gears. CONSTITUTION:The gear transmission device 82 is constituted by mounting spur gears 76A, 76B on the drive shaft 74 and meshing spur gears 78A, 78B respectively therewith. These spur gears 76A, 76B are so mounted that the teeth 86B of the spur gear 76B overlap on the middle of the teeth 86A of the spur gear 76A. The change in the load acting on the spur gear 76A and the change in the load acting on the spur gear 76B are, therefore, synthesized when the drive shaft is rotationally driven but the large load does not act on the spur gears 76A, 76B and, therefore, the generation of the unequal driving in the loads to be driven by the drive shaft does not arise.

摘要： PURPOSE:To prevent flawing of the surface of a photosensitive material and the degradation in image quality. CONSTITUTION:A transporting roller 44 is constituted as a so-called resin roller formed with a phenolic resin layer 44B in the outer peripheral part of a cylindrical arbor 44A consisting of metal such as aluminum. Fillers 51 consisting of glass fibers are packed in the phenolic resin layer 44B of the transporting roller 44. The parts projecting from the phenolic resin layer 44B are polished by low-pressure polishing, for example, sandblasting, by which the fillers 51 projecting from the phenolic resin layer 44B are previously removed.

摘要： PURPOSE:To prevent air in a processing solution processing part from flowing out of the inserting port of a photosensitive material. CONSTITUTION:A guide board 62 guiding a film 20 to an inserting roller pair 17A of an inserting rack 17 is provided inside the inserting port 15 formed on a machine frame 12. A duct 64 whose inside is hollow is disposed under the guide board, and communicates with the carrying path of the film by a slit 66 formed on the guide board. An intake fan 60 is disposed on the lower end of the duct, and the air between the inserting port and the inserting roller pair is sucked by the intake fan. The intake fan is operated in the case an automatic developing device stands by so as to prevent the air including component in processing solution inside the machine frame from flowing out of the inserting port.

摘要： PROBLEM TO BE SOLVED: To shorten the dissolution time of a treatment agent. SOLUTION: Water in an approximately necessary minimum amount for completely dissolving a treatment agent is supplied to a dissolution tank 104 and water in the dissolution tank 104 is stirred by rotating a paddle 115. After that, a piercing member 140 is operated to feed the treatment agent to the dissolution tank 104 from a bottle 122 and the stirring is continued. When the treatment agent in the dissolution tank 104 is almost completely dissolved, a prescribed amount of water is jetted to the inside of the bottle 122 to wash the inside of the bottle 122 and further the stirring is continued, the paddle 115 is stopped to stop stirring the water in the dissolution tank 104. After that, a prescribed amount of water is jetted to the inside of the bottle 122 to carry out levelling washing and on completion of stirring for a prescribed period, the treatment is finished.

摘要： PROBLEM TO BE SOLVED: To provide a photosensitive material processor which is improved in durability (specially chemical resistance and weatherability) and adaptive even when processing liquid etc., is highly active.
SOLUTION: The processing tank 20 of an automatic developing device is provided with replenishment nozzles 40 and 42 for respective processing tanks and water and the undiluted solution of the processing liquid can be supplied. The replenishment nozzles 40 and 42 are formed of olefinic thermoplastic elastomer and has high chemical resistance and weatherability. Consequently, even if water sticking on the replenishment nozzles 40 and 42 absorb sulfur dioxide to produce dilute sulfuric acid, those replenishment nozzles 40 and 42 are not affected and can maintain the starting function.
