Field of the Invention The present invention relates to a silver halide black-and-white photographic light-sensitive material processing apparatus, and more particularly to a silver halide black-and-white photographic light-sensitive material processing apparatus which prevents the adhesion of scale.

Description of the Related Art In a conventional silver halide black-and-white photographic light-sensitive material processing apparatus, a film having been photographed is conveyed by a conveying roller and sequentially immersed in a developing tank, a fixing tank and a washing tank to develop, fix, After each process of washing with water, the product is dried and processed in the drying section.

定量の処理後、水を交換する溜水方式が小規模の病院，
診療所等では主流となっており、処理量が少ない場合に
は何日も水洗水が貯溜，停滞することになる。In each of the above steps, each processing solution is replenished according to the processing of the film so that preferable processing conditions are always maintained. For example, in the washing tank, a large amount of water is supplied, and the liquid in the washing tank overflows and is replaced with new water, thereby enhancing the washing efficiency. In many cases, the washing water is supplied by the film detection mechanism only during the processing of the film, and when the processing is interrupted, the washing water is not replenished or purified by discharging the washing water. In this case, when the processing is completed, the replenishment of the washing water is stopped and the water is stored and stagnated in the processing tank. In addition, there is no replenishment of water during treatment, and after a certain amount of treatment, the stored water system that exchanges water is used in small hospitals.
This is the mainstream in clinics, etc., and if the treatment amount is small, the flush water will be stored and stagnated for days.

また、各処理ラック内の搬送ローラに付着した水垢が遊
離してフィルムに付着するといった問題もある。However, if the flush water is stored and stagnated, it is left for a long time, and water stains are generated. When the scale is generated, there arises a problem that the water rots to give off a bad odor. Further, if the generated scale adheres to the transport roller of the processing rack or if the scale of the transport roller itself of the processing rack immersed in water is generated, a slip occurs when the film is transported in the washing tank. For this reason, when the films are continuously processed, the films may be overlapped with each other, or the films may be bent and conveyed, resulting in conveyance failure.
Further, there is also a problem that the scale adhered to the transport roller in each processing rack is released and adheres to the film.

る。特に、感光材料が医療用Ｘ線フィルムの場合、付着
した水垢により誤診を生ずることがある。When the generated water stain adheres to the surface of the photosensitive material, the commercial value due to stains may be lost. In particular, when the light-sensitive material is a medical X-ray film, misdiagnosis may occur due to the adhered scale.

きな問題を引き起こす原因となる。Further, the drainage pipe of the flush tank is clogged with water stains. The clogging of the drainage pipe system causes a serious problem such that the washing water overflows from the washing tank because overflow is not discharged, and water is splashed on the photosensitive material processing apparatus itself and its surroundings.

なる。Therefore, in order to remove this scale, the washing tank must be washed regularly, which is troublesome. In particular, in the roller transport system, once water stains are generated, many transport mechanism parts are required, so cleaning them is extremely difficult work.

出来る。However, the use of unplasticized soft vinyl chloride has the effect of reducing the amount of scale produced in the overflow pipe. This is considered to be because the elution of the plasticizer in the unplasticized soft vinyl chloride is eliminated from the pipe, and the nutrient source for the microorganisms from the overflow pipe itself is reduced. The use of silicon in the flush water overflow pipe has the effect of reducing the amount of scale generated in the overflow pipe, as in the case of the unplasticized soft vinyl chloride. In addition, since the silicon hose is generally very flexible, if dirt in the pipe is found, the clogging substance can be easily removed by rubbing the silicon hose with a hand or the like. If a polyethylene hose is used for the flush water overflow pipe, the non-adhesive effect of polyethylene will cause the retention of the sensitizer elution substance such as gelatin and silver fine particles, which causes the generation of scale, and the treatment water substance, such as the treatment agent substance, in the overflow pipe. It will be difficult. Further, even when scales are generated in the overflow pipe, the scales are washed away by the flow of the overflow rinsing water, and the scales are prevented from growing. If a fluorine-based material is used for the flush water overflow pipe, the same effect as that of a polyethylene hose is produced. As a specific example of the fluorine-based material, P
There is a TFE hose. The same effect can be expected even if the liquid contact part of the hose is coated with a fluorine-based material.

As shown in the top view of FIG. 1 and FIG. 2A and the side sectional view of FIG. 2B, a trough 94 having a large number of holes 94A at the bottom, a filter medium 95, and a vinyl chloride plate 97 having a large number of holes. And the above are stored in order from the top, and a filtration tank 93 having an outlet 93A for pouring filtered water into the washing tank 8 at the bottom is installed at the upper part of the washing tank 8 and a pipe is provided from the water outlet at the bottom of the washing tank. The circulating wash water drawn by the passage 91 and the pump 92 is poured into the gutter 94 from the upper part of the filter tank 93.
