とができる。According to the first aspect of the invention, the hydraulic pressure of the portion of the processing tank located upstream of the photosensitive material in the conveying direction between the adjacent processing tanks is set to the downstream side of the photosensitive material in the conveying direction. Since the hydraulic pressure is smaller than that of the passage of the photosensitive material in the processing tank, the washing processing liquid may leak from the processing tank on the downstream side in the conveying direction of the photosensitive material to the processing tank on the upstream side in the conveying direction. It is possible to prevent the washing treatment liquid from leaking in the direction. That is, it is possible to prevent the washing treatment liquid from leaking in a direction opposite to the direction in which a new washing treatment liquid is supplied in the cascade, and the cascade can be performed normally.

る。Q: Amount of leakage of the washing treatment liquid which leaks from the processing bath on the downstream side in the transport direction to the processing bath on the upstream side in the transport direction per unit time D: Opening area of each processing bath Here, the adjacent treatments When a difference H is set in the liquid level of the washing treatment liquid between the tanks, the liquid level in the processing tank on the downstream side in the conveying direction is lowered by (H / 2) until the liquid levels become equal to each other, and The liquid level in the processing tank on the upstream side in the direction increases by (H / 2). That is, the leak amount of the washing treatment liquid that leaks from the treatment tank on the downstream side to the treatment tank on the upstream side until the liquid level becomes equal is (H / 2) × D.

場合の液面レベルが等しくなるまでの時間となる。The leakage amount ((H / 2) × D) of the washing treatment liquid which leaks from the treatment tank on the downstream side to the treatment tank on the upstream side until the liquid level becomes equal is conveyed through the passage per unit time. In the case where a value H divided by the leakage amount Q of the washing treatment liquid leaking from the treatment bath on the downstream side in the conveying direction to the treatment bath on the upstream side in the conveying direction is provided in the liquid level of the washing treatment liquid between the adjacent treatment tanks. It is the time until the liquid level becomes equal.

(1)式を満たすことは、許容時間内には隣接する処理

いことを意味する。Therefore, the expression (1) indicates that the time until the liquid surface level of the washing treatment liquid stored in the adjacent treatment tank becomes equal to is longer than the allowable time. That is,
Satisfying the equation (1) means that the liquid level of the washing treatment liquid stored in the adjacent treatment tanks does not become equal within the allowable time.

ードを正常に行うことができる。Therefore, within the allowable time, the liquid surface level of the washing processing liquid gradually decreases toward the upstream side in the conveying direction of the photosensitive material, that is, between the adjacent processing tanks, the upstream side in the conveying direction of the photosensitive material. It is possible to maintain a state in which the hydraulic pressure in the portion of the processing tank located on the side where the photosensitive material passes is made smaller than the hydraulic pressure of the portion where the photosensitive material passes in the processing tank located on the downstream side in the conveying direction of the photosensitive material. .
Therefore, it is possible to prevent the washing treatment liquid from leaking in the direction opposite to the direction in which a new washing treatment liquid is supplied in the cascade, and the cascade can be performed normally.

定する方が良い。The permissible time can be set according to the treatment time of one day so that the washing treatment liquid is maintained at a quality of a predetermined level or higher within the treatment time of one day. When the daily processing time is 8 hours, the allowable time may be set to about 6 hours. However, it is desirable to set this allowable time according to the amount of the washing treatment liquid stored in each treatment tank. That is, when the amount of the stored washing treatment liquid is large, even if a small amount of the washing treatment liquid leaks from the upstream side, the quality of the entire stored washing treatment liquid is unlikely to suddenly deteriorate. , When the amount of the stored washing treatment liquid is small, if a small amount of the washing treatment liquid leaks from the upstream side, the quality of the entire stored washing treatment liquid may be rapidly deteriorated. It is better to set the allowable time closer to the processing time of a day as the amount of the washing treatment liquid is smaller.

Further, by providing a difference in the liquid surface level of the washing processing liquid and providing a pressure difference in the air layer in each processing tank, the photosensitive material in the processing tank located upstream in the conveying direction of the photosensitive material between adjacent processing tanks can be prevented. The hydraulic pressure of the passing portion may be made smaller than the hydraulic pressure of the passing portion of the photosensitive material in the processing tank located on the downstream side in the conveying direction of the photosensitive material.

Liquid paraffin, liquid oil, or the like can be used as the inert liquid. As a result, the evaporation amount of the washing processing liquid in each processing tank can be reduced, and the influence of the evaporation of the washing processing liquid on the liquid pressure of the portion where the photosensitive material passes in each processing tank can be reduced.

Since it is not in contact with the liquid surface, the fluid disposed on the liquid surface of the processing tank other than the processing tanks on the most upstream side and the most downstream side has a peculiar effect that it is not necessary to consider the influence on the photosensitive material.

う特有の効果が得られる。Further, according to the invention of claim 4, since the inert fluid is arranged on the liquid surface of the washing treatment liquid in each treatment tank, the evaporation amount of the washing treatment liquid in each treatment tank is reduced,
It is possible to reduce the effect of evaporation of the washing processing liquid on the liquid pressure of the passage of the photosensitive material in each processing tank. Particularly, in a photosensitive material processing apparatus having three or more processing tanks storing the washing processing liquid, the conveyed photosensitive material is on the surface of the washing processing liquid in the processing tanks other than the processing tanks on the most upstream side and the most downstream side. Because it doesn't touch, the most upstream side,
A peculiar effect is obtained in that the fluid placed on the liquid surface of a processing tank other than the processing tank on the most downstream side does not need to consider the influence on the photosensitive material.
