Abstract

PURPOSE:To dry a photosensitive material in high finishing quality in a short time. CONSTITUTION:A film F is dried by the radiation heat supplied from an ultrared ray heater (not shown on the figure) in the first drying part 86 and the dry air which has a high temperature and is supplied from a spray pipe 47, and transported into the second drying part 92 before an excessively dried part is formed. Into the second drying part 92, the air which is dehumidified by a dehumidifying device 155 and has a low temperature and low humidity is supplied by a blower 166, and the film F is dried without being heated in the second drying chamber 92. Accordingly, the heating for the film F to the generation of the excessively dried part on the film F is prevented.

Detailed Description of the Invention [0001] [Industrial Application Field] The present invention relates to a photosensitive material processing apparatus and a photosensitive material processing apparatus.
This invention relates to a method for drying optical materials. [0002] With the progress in the electronics field,
Processing speed is also essential in the field of silver halide photographic processing.
It is becoming more and more sought after. Especially graphic arts feeling
Photosensitive materials such as materials, scanner materials, and X-ray materials
The need for rapid processing of fees is increasing
. The rapid processing referred to here means, for example, that the leading edge of the photosensitive material
After being inserted into a photosensitive material processing device such as a dynamic developing machine, it is developed,
It passes through a processing section consisting of fixing, washing, etc., and a drying section before being exposed to light.
The time it takes for the tip of the material to come out of the drying section is 20 seconds ~
This refers to a process that takes 60 seconds. These processes
Simply increase the transport speed of the photosensitive material processing equipment to shorten the time.
If you do this alone, various problems such as poor fixing and drying may occur.
Ru. [0003] In connection with this fixing failure, increasing the fixing speed
It is known to increase the concentration of thiosulfate for the purpose of
. In addition, the film surface of the photosensitive material is hardened to improve drying properties.
For this purpose, a water-soluble aluminum compound is included in the fixer.
It is also known and widely used. however
Water-soluble aluminum compounds reduce the fixing speed due to their hardening effect.
In order to speed up the fixing speed, it is necessary to add
does not contain any water-soluble aluminum compounds, or
If it contains only a very small amount, it will not be applied to the photosensitive material.
It is said that the swelling rate of the emulsion increases and the drying properties deteriorate.
There was a problem. In addition, a water-soluble acrylate that is a hardening agent in the fixer is used.
Although fixing speed can be improved by reducing the amount of aluminum salt,
However, it does not improve drying speed, which is important in rapid processing.
Traditionally, trials have been conducted to reduce the amount of water-soluble aluminum salts.
Very little was done. [0004] On the other hand, regarding the drying defect, the present application has already been filed.
Humans perform the drying process at high speed and ensure high finish quality.
We are proposing a drying device for photographic film processors that maintains the
(See Japanese Patent Application Laid-Open No. 1-260445). This photo fill
A drying device for a drying machine includes a plurality of drying chambers, and
It supplies drying air to the photographic film passing through the drying chamber.
In addition, the moisture content of the photographic film after drying and the moisture content in the outside air.
The temperature inside the drying chamber on the most downstream side is adjusted so that the
The photographic film is dried under controlled conditions. Problem to be Solved by the Invention However, the drying section
In photosensitive material processing equipment such as automatic processors equipped with
Photographic film is heated and dried when it is processed.
It may become over-dry in some areas, which may cause the finish to deteriorate.
In some cases, the quality deteriorated. In other words, automatic developing machine

The surface of the photosensitive material fed into the drying section is
has a lot of moisture attached to it. For this reason, moisture
Drying occurs in areas with a lot of adhesion and areas with no adhesion.
The progress is different, and there are areas where the drying progress is slow on the surface of the photosensitive material.
When drying is performed to achieve proper drying conditions
, the parts where drying progresses quickly are in the lapse rate drying stage in the late drying stage.
After drying properly, it receives a lot of heat. As a result, the areas where the drying progresses quickly become overdried.
, the emulsion layer shrinks and very thin wrinkles appear on the surface. Areas that have wrinkles due to over-drying and areas that are not over-dried.
Since the light reflectance differs between dark areas, it is possible to visually check whether the area is dry or not.
It may be confirmed as
was. [0006] The present invention has been made in consideration of the above facts.

Since the F is squeezed and dried by heating at the same time, the F is heated and dried at the same time.
The moisture adhering to the surface of film F is dried to some extent and completely removed.
It can shorten the drying time of the body. Also, the film at this time
F is moisture 18 attached to the surface as shown in Figure 7(B).
Most of 4 is removed by squeezing and drying.
Due to reasons such as the fact that the squeeze is not performed accurately and uniformly, etc.
, moisture 184 is attached to a part of the surface of the emulsion layer 182.
It is fed into the first drying section 86 of the drying section 20 in this state. [0101] Film F fed into first drying section 86

The water contained in the water 184 and the emulsion layer 182 evaporates.
(See FIG. 7(C)). As shown in Figure 7(D),
1 Moisture 184 on the surface when fed into the drying section 86
As the drying process progresses, the parts that had been attached will become attached to the surface.
Constant rate drying is performed in which the moisture 184 that was present evaporates. child
During constant rate drying, moisture 184 adheres to the surface.
The portion of the emulsion layer 182 that was
Because the latent heat is taken away, the temperature hardly rises, and the milk
The agent layer 182 is not dried. On the other hand, the first drying section 86
There is no moisture attached to the surface when it is sent inside.
The dried portion is sent to the first drying section 86 and at the same time becomes an emulsion.
Layer 182 is heated and its temperature increases. Therefore, the emulsion layer
The water contained in 182 gradually moves to the surface and evaporates.
Drying in the lapse rate drying stage progresses (see Figure 8), and Figure 7 (D)

All of the moisture 184 that had adhered to the surface of MuF has evaporated.
In some cases, the portion 186 to which the moisture had adhered becomes saturated with moisture.
The area where the moisture was not attached was
Minute 188 is in a semi-dry state. film
In this state, F is discharged from the first drying section 86 and

, low temperature, low humidity air is supplied and the lapse rate is reduced without being heated.
It is dried until the end of the drying phase. (See Figure 7(F)). Since the film F is not heated in the second drying section 92,
The area 188 to which no moisture was attached may become over-dry.
There is no such thing. Further, the drying speed in the second drying section 92 is
The drying speed in the drying section 86 is low and the air supplied is
It is dried so that it is in equilibrium with the relative humidity of the air. this
Therefore, the part 186 where moisture was attached and the area where moisture was attached
The difference in moisture content with the remaining part 188 is due to the progress of drying.
It gradually becomes smaller. As a result, film F becomes an emulsion.
A state in which the layer 182 has uniformly the same gloss and no uneven drying (
