Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a photosensitive material processing apparatus for processing silver halide photographic light-sensitive materials.

(Prior Art) Generally, when a silver halide photographic light-sensitive material (hereinafter referred to as "photosensitive material") after exposure is developed in an automatic developing machine, etc., it is developed in a developing section, and then the photosensitive material is transferred to a bleach-fixing section and a water-washing section. The pieces are then sent to the factory in order to be bleached, fixed, and washed with water.

When developing photosensitive materials, developer fatigue becomes a problem.
A replenishment method or a method of regenerating the developer is being tried [M, Ta5hiro, S, Ma

Under these circumstances, when developing a photosensitive material mainly composed of AgCj2 as silver halide, Br-
If such substances exist, there is a problem in that the development of the photosensitive material is inhibited. Such problems arise, for example, with photosensitive materials mainly composed of AgBr (for example, autopositive color photosensitive materials composed of AgBrCj2) and photosensitive materials mainly composed of AgC1 (for example, color vapor composed of AgCf). This occurs when a developer is used in common with the above. Specifically, Br-, etc. eluted during development of an autopositive color photosensitive material inhibits the development of color vapor.

Therefore, in order to prevent such suppression of development, if a development temperature or development time suitable for color vapor is selected, for example, development proceeds too much with autopositive color photosensitive materials, resulting in fogging.

To deal with the above problems, methods include changing the formulation of the developer depending on the composition of the silver halide constituting the photosensitive material, and changing the developing conditions such as developing time and developing temperature [Fuji Color Hobby Guide (manufactured by Fuji Photo Film Co., Ltd.: Senbar 287505-MW-5-1)].

Further examples include methods of removing Br-, etc. eluted into the developer by electrodialysis, physical adsorption, chemical adsorption, etc. (as described in the literature listed above).

(Problems to be Solved by the Invention) However, changing the developing prescription and developing conditions according to the type of light-sensitive material, that is, the composition of silver halide constituting the light-sensitive material, as described above, requires complicated equipment. There is a problem that the operation becomes complicated.

In addition, by applying electrodialysis, physical adsorption, chemical adsorption, etc.
The method of removing ``-'' etc. has the following problems.

First, the electrodialysis method requires a power source and has drawbacks such as the electrodes being easily worn out, as well as the large size of the device, which is disadvantageous in terms of cost. In addition, the physical adsorption method has poor efficiency in removing Br- and the like, resulting in high running costs.

Furthermore, in the chemisorption method, a conventional method has been used in which the overflow liquid is treated in batches using an ion exchange resin, which increases the size of the apparatus and is also disadvantageous in terms of cost.

Moreover, none of the above methods are sufficient.

Especially in the case of Br-, it is difficult to keep the Br- concentration below a certain value.
-, which is disadvantageous in terms of operation.

The present invention can easily remove Br present in a processing solution, especially a developer, and use AgB as a silver halide.
An object of the present invention is to provide a photosensitive material processing apparatus that can process a photosensitive material mainly composed of r and a photosensitive material mainly composed of AgCβ using the same developer.

[Means to solve the problem]

In order to achieve the above object, the photosensitive material processing apparatus of the present invention processes two or more types of imagewise exposed photosensitive materials having different emulsion components with the same processing solution, and the processing solution is stored in the processing solution. It has a container and a circulation section that takes out and circulates the stored processing liquid outside the container, and this circulation section is provided with a filter consisting of a rolled ball of ion exchange fiber wound around a cylindrical core material. The treatment liquid is filtered through a filter.

In the above, a plurality of filters are provided, and the plurality of filters are rotatable to form a filter section,
It is preferable that the filter be configured to be replaceable by rotation, and that the treatment liquid be filtered by successively passing through the plurality of filters.

[For production]

According to the present invention, a filter consisting of a rolled ball of ion exchange fibers wound around a cylindrical core material is installed in the circulation section that extracts and circulates the processing solution, particularly the developer, outside the container that stores the processing solution. and filter the developer.

Preferably, a plurality of filters are provided and each filter is replaced.

These filters are preferably replaced by rotation.

Further, the developer preferably passes through a plurality of filters in succession.

〔Example〕

Examples will be described with reference to the drawings. .

FIG. 1 shows an end view of a container (processing tank, particularly a developing tank 10) and a circulation section 11 of the photosensitive material If processing apparatus of the present invention.

Inside the developing tank 10 is a developing solution 1 as a processing solution in the present invention.
4, and a rack 16 is placed in this developer 14.

The rack 16 has a pair of side plates (only one side plate 2° is shown).
The side plates are supported parallel to each other.

Between this pair of side plates, rollers 24, 26, 28 are installed.
The trigrams are being handed out.

Rollers 30, 32 and 34, 36 are abutted on both sides of the roller 24 and the roller 26, respectively, and the hook is passed between the pair of side plates.

Further, rollers 38 and 40 are disposed on both sides of the roller 28, and a roller 42 is disposed in contact with the lower part thereof, so that a hook is similarly passed between the side plates.

Further, the developer 4W10 is provided with a liquid surface M50 so as to cover the liquid surface of the developer 14.

An opening (not shown) for carrying the photosensitive material 46 into and out of the developing tank 10 is provided in the liquid surface M50.

Therefore, as shown by the two-dot chain line in the figure, the liquid level 3ii5
The photosensitive material 46 guided and carried in by a predetermined means from the opening of
8, 40, and 42, it is reversed and raised, and is sent out from inside the developing device 10 by rollers 26 and 34, and rollers 24 and 30, and is transported to the next process.

The circulation unit 11 takes out the developer 14 stored in the developer tank 10 outside the developer tank 10 and circulates it. A pump P may be provided in the circulation section 11 to circulate the water.

This circulation section is provided with a filter section 12 that filters the developer 14 taken out.

This filter section 12 is composed of a plurality of filters F1 to F6 as shown in FIG.
It has a so-called turret type structure in which F6 is installed and its position changes by rotation.

Each of the filters F1 to F6 includes a core material 8 having a plurality of cylindrical through holes, as shown in FIGS. 1 and 2b.
It is composed of a rolled ball 82 of ion-exchange fiber rolled up into one roll. Each of the rolled balls 82 is housed in a case 83, and one open end of the core material 81 of the rolled balls 82 is connected to a sealing portion 8.
4, and the other open end of the core member 81 communicates with the outlet portion e of the case 83. As a result, the circulating developer 1
4 passes through the wound ball 82 and is ion-exchanged.

The inlet portions i and outlet portions e of the filters F1 to F6 can be opened in three directions, and are each provided with a three-way cock 85 so that the opening direction can be set as appropriate. Then, it is connected to a connecting pipe 91 of the circulation section 11 at a predetermined population portion i and an outlet portion e.

When filtering the developer 14, it is preferable to use a plurality of filters, and it is preferable to allow the developer to pass through the filters continuously.

FIG. 2b shows an example using filters F1 to F3.

The developer 14 taken out from the developer tank 10 flows into the inlet portion i of the filter F1 as shown by the arrow, passes through the filters Fl, F2, and F3 in order, and then enters the filter F3.
It flows out from the outlet part e of the developer tank 10 and returns to the developer tank 10 again.

In addition, in FIG. 1, only the filter F1 is illustrated, and illustration of other filters is omitted.

In this case, the filters F1 to F3 used when filtering the developer 14 are used by passing the developer 14 sequentially through the filters Fl, F2, F3. F3
The exchange ability of the ion exchange fiber decreases in this order.

Therefore, when using the system using three filters, it is preferable that after using the filters F1 to F3, the filters to be used are replaced at an appropriate time to use the filters F2 to F4. Similarly, sequential filters F3 to F5. It may be used by replacing filters F4 to F6.

In this way, since a plurality of filters F1 to F6 are sequentially replaced and used, replacement is easy by simply replacing the ion exchange tnmia filter with respect to the filters that are not being used. Moreover, for such a filter, it is only necessary to regenerate the exchange ability of the ion exchange fiber, and regeneration becomes easy.

Ion exchange 1a I used in the filter in the present invention
The purpose of a is to remove Br-, etc. present in the developer, and any anion exchangeable material may be used.

Specifically, for example, trimethylammonium type (
The product name TIN-200 (manufactured by Toshi ■) is used.

This material is made into fibers by inserting a core of polypropylene into a matrix in which trimethylammonium ions are introduced as ion exchange groups into cross-linked polystyrene.

Ion-exchange fibers have a fiber diameter of approximately several tens of μm and a larger specific area than granular resins, allowing the ion-exchange reaction to proceed efficiently.

Therefore, in the present invention, Br- in the developer 14 can be almost completely removed. Furthermore, not only Br-, but also halogen ions such as ■- and antifoggants eluted into the developer can be removed.

For this reason, a developer for developing a photosensitive material mainly composed of AgBr as a silver halide, such as an autopositive photosensitive material, and a developer for developing a photosensitive material mainly composed of AgCIL as a silver halide, such as a negative color vapor. It is possible to share the same developer as the one used for developing other materials.

This is because a photosensitive material mainly composed of AgBr can remove Br- eluted into a developer.

Therefore, in the present invention, two or more types of light-sensitive materials having different emulsion components can be developed with the same developer.

In the illustrated example, the number of filters in the filter section 12 is six, and three of them are sequentially used at the same time. However, the number of filters used at the same time may be changed, and The structure may be such that the developer 14 can be circulated.

Further, although it is preferable to exchange using the turret method as described above, the replacement is not limited to this, and any exchange is possible.

The developer used in the present invention may be any known black and white developer or color developer, and may be appropriately selected depending on the photosensitive material and the like.

Furthermore, the developer tank 10 according to the present invention is not limited to the configuration of the transport path as shown in FIG. 1, but may have any known configuration.

The developing device of the present invention can be applied to an automatic developing machine, a developing section of a silver halide photocopier, and the like.

Furthermore, the photosensitive material processing apparatus of the present invention can be used in photosensitive material processing apparatuses in which the developing step and the next bleach-fixing step are performed separately, or in a type in which developing and fixing are performed in a single bath. It is also possible to apply it to photosensitive material processing equipment.

It can also be applied to a photosensitive material processing apparatus for color reversal processing, in which case either a replenishment type or a non-replenishment type may be used.

【Effect of the invention〕

According to the present invention, Br present in the processing solution, especially the developer
- etc. can be completely removed with simple operations. Therefore, it is possible to develop a photosensitive material mainly composed of AgBr as a silver halide and a photosensitive material mainly composed of AgC1 using the same developer.

Furthermore, since a filter made of wound balls of ion exchange fibers is used, it has a high ability to remove Br-, has little pressure loss, and is easy to regenerate. Furthermore, the device has a simple structure and is advantageous in terms of cost.

The present inventor conducted various experiments in order to confirm the above-mentioned effects, and an example thereof will be shown below.
