Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は印画紙を現像処理する写真処理装置に係り、詳
細には所謂超節水水洗方式の写真処理装置に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic processor for developing photographic paper, and more particularly to a so-called super water-saving rinsing photographic processor.
印画紙を現像処理する場合には、印画紙を現像槽、漂白
定着槽、水洗槽及び乾燥槽へ順次案内するようになって
いる。When developing a photographic paper, the photographic paper is sequentially guided to a developing tank, a bleach-fixing tank, a water washing tank and a drying tank.
この現像処理装置の水洗槽は通過する印画紙へ洗浄水を
流水供給する構成であり、幅寸法８．２５cmの印画紙を
長さ１ｍに渡って水洗する場合には８００ｍの洗浄水
を必要とする。The washing tank of this development processing device is configured to supply washing water to the photographic paper passing therethrough. When rinsing a photographic paper having a width of 8.25 cm over a length of 1 m, 800 m of washing water is required. To do.
これに対して、洗浄水に添加薬品を加えて洗浄槽へこの
洗浄水を貯留し、現像漂白後の印画紙を浸漬させながら
搬送する方式の洗浄部を設けることにより、洗浄水の必
要量が1/40の２０ｍに減少する。On the other hand, by adding an additive chemical to the wash water, storing this wash water in the wash tank, and providing a washing section of the system that conveys the photographic paper after development and bleaching while soaking it, the required amount of wash water is reduced. It is reduced to 20m, which is 1/40.
このようないわゆる超節水水洗方式の写真処理装置にあ

ち込まれて悪影響を及ぼす原因となる。In such a so-called super water-saving washing method, an endless belt that guides the photographic paper to each processing section sequentially circulates to each processing section, and thus is included in the bleach-fixing tank (NH
4 ) 2 S 2 O 3 (ammonium thiosulfate) is brought into the developing tank and causes an adverse effect.
すなわち漂白定着部の処理液内に含まれるチオ硫酸アン
モニウムは無端ベルトによって印画紙と共に次の浸漬洗

は５×１０１５Ｖ／Ｖが限界であり、チオ硫酸イオンと
しては１００×５×１０−３ｍ／（Ｐ１）である。That is, ammonium thiosulfate contained in the processing solution in the bleach-fixing section is passed through the next immersion cleaning section together with the printing paper to the drying section by the endless belt, and is dried and solidified on the belt surface. Although the amount of liquid that adheres to this belt is about 1/10 that of photographic paper, the photographic paper after development leaves the endless belt and is sent to the next process, whereas the endless belt returns to the developing tank. And circulate. Therefore, ammonium thiosulfate is eluted into the developing tank and becomes thiosulfate ions, which contaminates the developing solution. The ratio of the amount of processing liquid in the bleach-fixing tank to the amount of processing liquid in the developing tank is limited to 5 × 10 15 V / V, and the thiosulfate ion is 100 × 5 × 10 −3 m / (P 1 ). .
本発明は上記事実を考慮し、いわゆる超節水水洗方式の
写真処理装置においても、無端ベルトが漂白定着部から
持ち出された処理液を離脱させて現像部に悪影響を及ぼ
すことがない写真処理装置を得ることが目的である。In consideration of the above facts, the present invention provides a photographic processing apparatus that does not adversely affect the developing section by separating the processing solution carried out from the bleach-fixing section by the endless belt even in a so-called ultra-water-saving washing method. The purpose is to obtain.
本発明に係る写真処理装置は、印画紙を処理する現像
部、漂白定着部、浸漬洗浄部及び乾燥部を循環するよう
に掛け渡された無端ベルトと、前記印画紙の先端を前記
無端ベルトに係止し無端ベルトの駆動によって印画紙を
無端ベルトの側方で所定間隔離間させて搬送可能とする
先導クリップと、前記乾燥部の前に設けられ前記印画紙
と所定間隔離間された前記無端ベルトの表裏両面のみを
洗浄する無端ベルト水洗部と、を有している。The photographic processing apparatus according to the present invention is an endless belt which is laid so as to circulate through a developing section for processing photographic paper, a bleach-fixing section, a dip cleaning section and a drying section, and the end of the photographic paper is set to the endless belt. A leading clip that locks and allows the photographic paper to be conveyed by being separated from the endless belt by a predetermined distance by driving the endless belt, and the endless belt provided in front of the drying section and separated from the photographic paper by a predetermined distance. And an endless belt washing section for washing only the front and back sides.
したがって、本発明では、印画紙を無端ベルトと所定の
間隔を隔てた状態で搬送し、印画紙と共に無端ベルトが
漂白定着槽を過ぎると無端ベルトの表裏両面のみを無端
ベルト水洗部で水洗する。これによって、無端ベルトか
ら漂白定着部で付着した処理液を離脱させる。Therefore, in the present invention, the photographic printing paper is conveyed at a predetermined distance from the endless belt, and when the photographic printing paper and the endless belt pass through the bleach-fixing tank, only the front and back surfaces of the endless belt are washed in the endless belt rinsing section. As a result, the processing liquid attached at the bleach-fixing section is released from the endless belt.
無端ベルトは、漂白定着液成分が付着した状態で乾燥部
へ至ることがなく、乾燥部で漂白定着液成分が固化して
無端ベルトに付着するのを防止でき、印画紙の現像処理
を円滑に行うことができる。The endless belt does not reach the drying section with the bleach-fixing liquid component adhering to it, and it is possible to prevent the bleach-fixing liquid component from solidifying and adhering to the endless belt in the drying unit, which facilitates the photographic paper development process. It can be carried out.
無端ベルトに付着する処理液は印画紙に比べて1/10程度
であるため、水洗水量は極めて少なく、一例として洗浄
水を少量噴射させるのみで確実な処理液離脱が可能にな
る。Since the treatment liquid adhering to the endless belt is about 1/10 that of printing paper, the amount of washing water is extremely small, and as an example, it is possible to reliably remove the treatment liquid by spraying a small amount of washing water.
無端ベルト水洗部へ送り込む水は現像部、漂白定着部等
の温度管理用として用いる熱交換器の冷却水排水を流用
することが可能である。As water to be sent to the endless belt washing section, it is possible to use cooling water drainage of a heat exchanger used for temperature control of a developing section, a bleach-fixing section and the like.

き出される。By driving the endless belt 26, the endless belt 2
6 is sequentially moved into each processing tank of the photographic processing apparatus 10, and accordingly, the photographic printing paper 30 is also led by the endless belt 26 to be developed and bleach-fixed in the developing tank 12 and the bleach-fixing tank 14. After that, the cleaning section 16A is reached. Further photographic paper 30
Is passed through the washing sections 16B, 16C, 16D and 16E, and after the bleach-fixing solution 38 is washed, it is drawn out to the belt washing section 18.

ま洗浄部１６Ｅから引き出される。The bleach-fixing solution 38 is washed off from the photographic printing paper 30 and the endless belt 26 that pass through the washing sections 16A to 16E, but the washing tank of this is different from the conventional method of supplying washing water with running water.
Since the bleach-fixing solution 38 has a weak washing-off force, a part of the bleach-fixing solution 38 is pulled out from the cleaning section 16E while being attached to the endless belt 26 and the photographic paper 30.

はなく、問題はない。In this embodiment, the endless belt 2 reaching the belt washing section 18
Both the front and back surfaces 6 are washed with the belt washing water 60 from the jet pipe 58. Since the bleach-fixing solution 38 adhering to the endless belt 26 is about 1/10 of the photographic printing paper 30, the amount of the belt cleaning water 60 sprayed from the spraying pipe 58 is sufficient, and most of the bleach-fixing solution 38 is sufficient. Is released.
Since the jet water 58 jets the washing water 60 only to the endless belt 26, the washing water 60 is not jetted to the photographic printing paper 30 and there is no problem.
このため乾燥部２０へ至った無端ベルト２６からはすで
に漂白定着液３８が離脱されており、漂白定着液３８が
無端ベルト２６の表面へ固化することはない。Therefore, the bleach-fixing solution 38 has already been separated from the endless belt 26 reaching the drying section 20, and the bleaching-fixing solution 38 does not solidify on the surface of the endless belt 26.
乾燥部２０から引き出された印画紙３０は先導クリップ
３２から取り外されて次工程へと送られる。The printing paper 30 pulled out from the drying unit 20 is detached from the leading clip 32 and sent to the next step.

Therefore, the developing tank 12
It does not contaminate the developer 36 therein.
