Description

Detailed Description of the Invention [0001] This invention relates to silver halide photography, etc.
Photosensitive materials, especially photosensitive material processing for negative film processing
Related to the processing equipment. [0002] 2. Description of the Related Art One of the light-sensitive materials for silver halide photography
In a photosensitive material processing device that develops a certain negative film
Should be used as much as possible when transporting and discharging negative film.
It is necessary to take a method that does not cause stains, water stains, or scratches.
So far, various kinds of devices have been devised. [0003] However, development, etc.
When it is sent to the drying process after being processed in the processing tank of
If not done, not only is the drying efficiency poor, but water stains
Becomes a stain and adheres to the negative film,
There is a risk that it will appear on the paper due to burning
there were. Therefore, it is necessary to devise a material having good water absorption.
Have been devised, and measures such as increasing the transport pressure have been made.
However, on the contrary, there is a risk of impairing the straightness of conveyance, and
There was a risk of damage to the material itself. Nevertheless, the water supply of the materials has hitherto been possible.
The change in expansion and the pressure applied to the photosensitive material
Was not considered. Regarding the axial direction of the transport roller
Since the unevenness of all pressures changes depending on the degree of water absorption,
When changing to thinner photosensitive materials, considerable stress strain
Is likely to occur. For example, the risk of tearing
is there. [0006] Up to now, generally, the peripheral surface of the transport roller is 5
It was covered with a water-absorbing material such as a sponge of about 6 mm. Su
In order to improve the quiz quality
It is possible to keep the gap between the water roller and the hard roller small.
It is desirable to use an elastic body such as polyurethane to strengthen the nip.
I was doing However, on the contrary, increase of driving load and
Due to the meandering of the feeding, the conveyance of the photosensitive material was hindered. Further, in the case of a roller using a water absorbing material,
Generally, when water is absorbed, it swells and the outer diameter increases. For example,
About 10% in the thickness direction for porous polyurethane materials
It In addition, there is a negative
And a roller made of a porous polyurethane material having a hardness of 15 degrees.
In combination with PPE roller (hard),
Fires when the urethane roller is compressed by 0.4 mm or more.
It was alive. [0008] A material having a higher water absorption is more swelled, and thus has a larger size.
It was a problem, but not managed.
This is because the negative film has so far been about 130 μm, for example.
That wasn't a problem, but recently, the 50-90 μm
It is changing to a thickness base, which is a problem. In addition, a negative film is stored in the leader section.
After being carried and transported through the processing tank and drying section and discharged,
The film should hang down to avoid contact with other members.
However, the guide of the reader is on the bottom side.
The rigidity of the leader is improved by devising the shape of the holding means provided on the
Since it is being sent upwards using
The carrying force is reduced and, as a result,
Negative film sticks to the leader while trying to come out first.
Danger of peeling or jamming when trying to cross over
There was a nature. Further, the negative film is conveyed in the processing tank.
When processing, the processing liquid in the processing layer may become dirty or the performance may deteriorate.
If it deteriorates, the negative film may become dirty and the quality
There was a risk that it would be a bad treatment. Therefore, the treatment tank
To collect the overflow liquid from these and make reclaimed water,
The number of treatment equipment connected to the waste liquid treatment equipment has also increased. Only
However, the container part that stores the waste liquid in this waste liquid treatment device
Recycled water storage to store reclaimed water after it has been processed and concentrated
Overflowed when the water level (liquid level) of the liquid in the container was confused
If you try to pull it out with a pump while it is empty, extra dirt will be mixed.
There was also a risk of entering. [0011] [Means for Solving the Problems] One of the Problems
Is a post-processing step after the photosensitive material has been developed and sent to the drying section.
On the surface of the photosensitive material, or inside the drying section
Two rollers with a squeeze function to remove accumulated water
While forming a squeeze means by pressing and facing each other,
At least one of the rollers of this squeeze means
Like forming a surface layer with a porous polyurethane material
However, the thickness of this surface layer is free over the entire circumference in a dry state.
Photosensitivity characterized by being 0.1 mm or more and 3 mm or less
After the development processing of the light-sensitive material by the material processing device,
Therefore, before sending to the drying section, or inside the drying section,
Squeeze function to remove the moisture adhering to the surface of the optical material
A squeeze means in which two rollers are pressed against each other
With this, the number of rollers of this squeeze means
Both rollers should be made of water-absorbing material
However, the thickness of the surface layer is t in the free state when dried.₀
mm, thickness at saturated water absorption t in free state₁If
In the free state part, With a photosensitive material processing apparatus characterized by having the relationship of
Can be achieved. In particular, as the water absorbing material, a porous polyurethane is used.
In particular, the hardness is 10 to 70 degrees.
Preferably. Another problem is that the photosensitive material is processed.
The waste liquid discharged from the processing tank containing the processing liquid is temporarily stored.
In a photosensitive material processing device with a built-in waste liquid storage container
The upper limit position of the liquid level of the waste liquid storage container is
A waste liquid cycle that is lower than the liquid level upper limit position and collects waste liquid to the outside.
Photosensitive material provided higher than the lowest liquid level of the container
With a processing device and the tip of a pipe for collecting waste liquid to the outside
An on-off valve is installed nearby, and the material is discharged from the processing tank for photosensitive materials.
For the waste liquid treatment method of connecting the waste liquid to the waste liquid treatment equipment with water supply
The waste liquid treatment device includes a waste liquid tank unit and a recycled water storage unit.
The piping for transferring the waste liquid from the processing tank is divided into
The upper limit that outputs a signal when the amount of waste liquid exceeds the upper limit connected to the
Includes liquid level detection means and lower limit liquid level detection means
Regenerated water is stored in the reprocessing water and is supplied to the treatment tank.
The Kurabe is equipped with liquid level detection means that detects the upper and lower limits of the recycled water.
It can be achieved by a method of treating waste liquid. Further, a negative film to be developed.
Hold it in the leader section and carry this leader section to the top.
In the light-sensitive material processing apparatus for feeding and processing,
The leader section is ejected from the drying section after processing.
A guide that guides only one of the width direction upwards with respect to the exit direction.
Has a guide plate, the leader is guided by the guide plate,
After losing the carrying force, the trailing edge of the leader section in the discharge direction
The leader holding means for holding the
According to the photosensitive material processing device formed approximately in the center of the exit,
The problem can be solved. On the other hand, the solid processing agent was added.
Supply from a solid processing agent container such as a cartridge to a specified processing tank.
The supply path means for supplying is formed detachably,
This supply route means should not be confused with each solid processing agent.
In advance, set a predetermined route at the position of the solid storage container.
A photosensitive member formed with engaging means so that only the means can be loaded.
The material processing device and the supply route must be shooters.
Both are preferable. [0016] [Example] In processing a light-sensitive material, handling after development is large.
Negative film that is cut and contains water and weakens in strength
Also, the photosensitive paper is easy to tear,
To prevent unnecessary stress from being applied to the transport rollers,
In consideration of this, the configuration considered will be described below. FIG. 1 schematically shows a process of processing a light-sensitive material.
The negative film F, which is a typical photosensitive material,

Gafilm F is a developing tank 2 and a bleaching tank of the photosensitive material processing apparatus 1.
3, processing tanks such as fixing tank 4 and stabilizing tank 5 are provided.
From the processing solution from the other processing tanks.
The negative film F that came out rises from the liquid surface and rises,
Enter the drying section 6 with the emulsion side of Rum F facing up. Where the figure

Forming the squeezing means A that is oriented,
R₁, R₂At least one of the rollers as shown in FIG.
To form the surface layer 10 with a porous polyurethane material
And the thickness of the surface layer 10 is around the entire circumference in a dry state.
At 0.1 mm or more and 3 mm or less. In this example
Is the transport roller R₂Is PPE (polyphenylene ethere)
Le) was adopted. At this time, the transport roller R₂Is due to water absorption
It is in a state where it hardly expands. Further, the transport roller R₁Polyurethane material
The inside of the is a non-absorbent rigid or elastic body that absorbs water during use.
The diameter does not change with the degree. Alternatively, the final treatment inside the drying section 6
Conveyor roller R at the entrance 60, which is immediately next to the tank₃,
R_FourOn at least one of the
Even when a urethane material is used, tearing during transportation is similar.
It was possible to eliminate curved transport. Similarly, even if the water absorption material has the same water absorption amount.
The degree of swelling is different, and even the same polyurethane can absorb water
The degree of expansion (moisture) is different, resulting in squeeze
Pressure on the roller on the other side of the roller changes and
A change in pressure distribution occurs in the la-axis direction. Accordingly
The results of repeated examinations were conducted with varying degrees of expansion due to water absorption.
As a result, the results were obtained as follows. While the squeeze means A is formed,
In the embodiment, the squeeze means A faces the photosensitive material coating surface.
Porous polyurethane for the roller that is pressed against the roller
Materials such as porous polyurethane and polyvinyl alcohol
Polyethylene sintered body, water-absorbent synthetic leather (Clary
No) For felt cloth, chlorosulphonated polyethylene)
Therefore, the surface layer 10 is formed, and the surface layer 10 is formed.

hand, [0022] [Equation 1] Has a relationship to define a more universal coating on the roller.
Can be used and has less bending regardless of the usage condition
It is now possible to provide transportation. In this embodiment, the inside of the water absorbing material is made of PP.
E (polyphenylene ether) coated on stainless steel shaft
However, it is used as the shaft material. Experimental value (25 ° C, humidity 60%) Overlapping pressure of both rollers 5 / 100mm (1) Squeeze material coated roller shaft diameter (diameter of high hardness part) 15 mm       Opposing roller diameter (PPE) 20 mm 1. Cover the roller with a squeeze material (porous polyurethane).
Cover (unit mm) [0025] [Table 1] Transport function [0026] [Table 2] Here, the amount of displacement includes a 1 mm negative film,
Maximum in 10 cases of the amount of deviation (mm) in the axial direction before coming out
It is a value. The transfer speed is 200 to 800 mm / min (
The amount of deviation is too large
It didn't change. Total negative film thickness is 140 μm
It From these results, it was confirmed that porous polyurethane was used.
In case of dryness, the coating when dried is 3 mm or less and 0.1 mm or less.
The above turned out to be preferable. However, since the water absorption performance is considerably lowered,
With a porous polyurethane, compression of 0.1 mm or more absorbs water
It was also the lower limit to maintain. Actually 0.1-0.3m
When using a squeeze roller with a coating thickness of m
It is better to increase the number. Next, in addition to the porous polyurethane,
Squeeze Larino or Chlorosulfonated Polyethylene
When used as a roller for some parts, it is suitable because it swells.
It is also possible to specify the coating thickness of the surface layer of the water absorbing roller.
Came. The thickness of the surface layer of the water absorbing material is free when dry.
The thickness is t₀mm The thickness when saturated with water is t₁When
The free state part (pressure from the opposing roller is
In the unworn state part), [0032] (Equation 2) With a photosensitive material processing apparatus characterized by having the relationship of
Can be achieved. That is, if the material has a small degree of swelling,
Even if the coating thickness is increased, it does not affect the transportation and
The opposite is true for highly saturated materials. Polyethylene sintered body,
With water-absorbent synthetic leather (clarino), even if it is thick, it will not be conveyed properly.
It was always low. Polyvinyl alcohol, chlorosulfur
Γ was about 0.08 for phonated polyethylene
The coating was 3.75 although there was some conveyance failure.
