Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic developing machine for silver halide photographic light-sensitive materials, and more specifically, to an automatic developing machine for silver halide photographic light-sensitive materials in which a poly container is discharged and a solid processing agent is used to eliminate a melting operation. Regarding the machine.

[0002]

BACKGROUND OF THE INVENTION A silver halide photographic light-sensitive material (hereinafter sometimes referred to as a light-sensitive material or a photographic material) is usually subjected to steps such as development, desilvering, washing and stabilization after exposure. Black-and-white developing solution, color developing solution for developing, bleaching solution, bleach-fixing solution, fixing solution for desilvering, tap water or ion-exchanged water for washing, and stabilizing solution for stabilizing. To be done. The light-sensitive material is usually dipped in each processing solution whose temperature is adjusted to 30 to 40 ° C. and processed.

Such processing is usually carried out by an automatic processor (hereinafter,
It may be referred to as an automatic processing machine) or the like, and is sequentially carried between the processing tanks containing the processing liquid. Here, the term "automatic developing machine" refers to a developing machine having a developing section, a desilvering section, a washing or stabilizing section and a drying section, and having means for automatically automatically transferring the photographic light-sensitive material to each processing tank section. Generally referred to.

In this case, conventionally, a method of replenishing the replenishment liquid of each treatment liquid in order to keep the activity of the treatment liquid in the treatment tank constant has been adopted. Is supplied to the processing tank at appropriate times to perform the processing work.

In such a case, the replenishing liquid itself stored in the replenishing tank is usually prepared in another place and supplied into the replenishing tank as needed. The following manual methods have been adopted from.

That is, a processing agent for silver halide photographic light-sensitive materials (hereinafter sometimes referred to as a photographic processing agent) is supplied to the user in the form of powder or a concentrated liquid, and in the case of use, it is fixed in the case of powder. It is adjusted by dissolving in a certain amount of water, and in the case of a thick liquid, it is mixed with water to a certain amount,
Used by dissolving and diluting.

The replenishment tank may be installed beside the automatic processing machine, and it is necessary to secure a considerable space. Also,
Even in the minilab, which has been increasing rapidly in recent years, the refill tank is built into the machine itself, but in this case as well, it is necessary to secure a space for the refill tank.

Replenishment processing agents are divided into several parts for good and stable performance during photographic processing. For example, the replenisher for the bleach-fixing solution for color is divided into concentrated parts of ferric organic acid salt which is an oxidizing agent and concentrated parts of thiosulfate which is a reducing agent. It is used by mixing thick salt parts and thick parts containing thiosulfate and adding a certain amount of water.

The concentrated parts are put in a container such as a plastic container, and these are put together in an outer bag (for example, a cardboard box) and sold as a unit.

The replenishment treating agent in which the above-mentioned parts agent is made into a kit is used after dissolving, diluting and mixing and finishing to a fixed amount, but the replenishing treating agent has the following drawbacks.

That is, each parts agent is individually put in a container, and depending on the replenishing treatment agent, several parts agents are included, and the number of parts agents becomes considerably large when it becomes one unit. Not only did it take a lot of space, but there was also a problem with the disposal of empty containers. Also, if the parts agent that composes the replenishment treatment agent consists of several types, each part agent is individually put and scattered, so it takes time to find each part agent, and the working efficiency of the liquid preparation is high. Was significantly reduced.

On the other hand, in recent years, environmental protection and resource saving have been strongly demanded mainly in Europe and the United States, and a plastic container for storing the above-mentioned concentrated processing liquid has been a particular problem in photography. That is, although plastic containers for photographic processing agents are low in cost, convenient for storage and transportation, and have excellent chemical resistance, empty containers are landfilled as industrial waste, discarded, or incinerated. However, the plastic container has almost no biodegradability, and when it is accumulated and incinerated, a large amount of carbon dioxide gas is generated, which causes a problem such as global warming. In addition, as a problem on the user side, it has been pointed out that a large number of plastic containers are piled up in a narrow working space to further reduce the space.

As a method of eliminating the above-mentioned problem, that is, a method of eliminating the plastic container for packaging the liquid treating agent, it is conceivable that the treating agent is simply pulverized. However, it has drawbacks such as time-consuming dissolution and easy scattering of powder, and although it is partially used in large laboratories, it is not applicable to over-the-counter treatment such as minilabs.

Proposals have been made to solve the problem and to make full use of the solid processing agent. For example, JP-A-51-61837
Japanese Patent Publication discloses a photographic tablet containing a disintegrant, and proposes a technique for improving the solubility.

Further, JP-A Nos. 2-109042 and 2-1.
09043, 3-39735 and 3-3973.
No. 9 discloses a method of using a granulated photographic processing agent having a certain average particle diameter, and proposes improvement of prevention of powder scattering.

However, in both cases, the dissolution work must be performed, and the complexity of the dissolution work when using the liquid kit cannot be improved.

As a method for eliminating the need for the melting operation, Japanese Patent Laid-Open No. 11344/1993 discloses the method of extruding a paste-like part agent from each unit container in an amount corresponding to the mixing ratio of the part agent.
Mix the extruded parts agent with a certain amount of dissolved water,
A technique of diluting and supplying to a predetermined concentration is disclosed.

Similarly, the area of the processed photographic light-sensitive material is detected, and the solid processing agent such as granules or tablets and the dissolved water are mixed and dissolved by the replenishing solution preparing section and supplied to the processing tank at regular intervals. Methods have also been proposed.

Further, a method has been proposed in which a solid processing agent such as granules, tablets, and pastes and makeup water are directly added to a processing tank or a portion connected to the processing tank according to processing information of the light-sensitive material. .

In the above-mentioned technique for preparing a replenishing solution, since it dissolves in dissolved water and is replenished immediately, the solubility becomes insufficient, and stirring means such as a mixer is provided, or the dissolved water is heated up. It is necessary to take measures such as increasing the solubility, which increases the cost of the device.

In addition, in the method of adding directly to the processing section, since it is added to the processing solution adjusted to the processing temperature, the solubility is improved, but it is impossible to dissolve instantly, so that the dissolution residue is left in the processing section. However, there is a drawback in that it may be mixed in with the photosensitive material, adhere to the photosensitive material, or clog the pump or filter to cause an environmental problem.

Further, when each part agent of the solid processing agent is dissolved at the same time, a high-concentration portion is partially generated, and an insoluble precipitate is generated, or precipitation is caused to easily adhere to the wall surface of the rack or the tank. It is necessary to shift the timing of the parts agent to add it, and the software becomes complicated,
In addition, when large-scale processing is performed, there arises inconvenience such that dissolution is delayed.

Therefore, it has been strongly desired to solve the solubility and the formation of precipitates when such a solid processing agent is automatically supplied depending on the processing.

[0024]

SUMMARY OF THE INVENTION An object of the present invention is to provide a low-pollution automatic developing machine which does not substantially use a plastic container, and secondly an automatic developing machine which is free from manual melting work. Thirdly, the third object is to provide an automatic developing machine which does not generate insoluble matters and precipitates when a solid processing agent is used.

Including things. The present invention also includes pastes and slurries, but tablets and granules are preferable, and tablets are the most preferable in order to exert the effects of the present invention more effectively.

The granules referred to in the present invention are obtained by subjecting a powder to a granulation step and mean a granular material having a particle size of 50 to 5000 μm. The term “tablet” as used in the present invention means a powder obtained by compression-molding into a certain shape, or a tablet obtained by once granulating and then compression-molding into a certain shape.

A preferable tablet manufacturing method is a method in which a solid processing agent in powder form is granulated and then a tableting step is performed. The solid processing agent formed by the tableting process by simply mixing the solid processing agent components has poor solubility and storability, resulting in unstable photographic performance.

The granulation method for tablet formation includes rolling granulation,
Known methods such as extrusion granulation, compression granulation, crushing granulation, stirring granulation, fluidized bed granulation, and spray drying granulation can be used. The obtained granulated product preferably has an average particle size of 100 to 800 μm, more preferably 200 to 800 μm.

The solid processing agent obtained by compression under pressure can have any shape, but a cylindrical type, so-called tablet is preferable from the viewpoint of productivity and handleability. More preferably, during granulation, the above-mentioned effects become more remarkable by separately granulating each component, for example, an alkali agent, a reducing agent, a bleaching agent, a preservative and the like.

The solid processing agents used in the present invention can be used in all photographic processing agents such as color developing agents, black and white developing agents, bleaching agents, fixing agents, bleach-fixing agents and stabilizers.

According to the embodiment of the present invention, it is most preferable that all the processing agents are solid processing agents, but it is preferable that at least the color developing agent is a solid processing agent. That is, since the color developer component contains a large number of components which cause a chemical reaction with each other and also contains a component which is difficult to dissolve, the effect of the present invention is most remarkable. More preferably, a bleach-fixing agent, a bleaching agent, and a fixing agent other than the color developing agent are solidified.

To solidify the photographic processing agent, a concentrated liquid or fine powder or granular photographic processing agent and a water-soluble binder are kneaded and molded, or a water-soluble binder is temporarily formed on the surface of the photographic processing agent.
