DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic processor for a silver halide photographic light-sensitive material, and more particularly to a compact automatic processor and improved workability, and furthermore, the stability of chemicals is remarkably improved. And to an automatic developing machine which can easily reduce replenishment.

[0002]

2. Description of the Related Art A silver halide photographic light-sensitive material (hereinafter sometimes referred to as a light-sensitive material or a photographic material) is exposed to light.
Processing is performed by steps such as development, desilvering, washing, and stabilization.
A black and white developer, a color developer, a bleaching solution, a bleach-fixing solution, a fixing solution for desilvering, a tap water or ion-exchanged water for washing, and a stabilizing solution for stabilization are used for development.

A liquid having a processing function for performing each of these processing steps is called a processing liquid. Each processing solution is usually 30
The temperature is adjusted to -40 ° C, and the photographic material is immersed in these processing solutions for processing.

[0004] Such processing is usually carried out by using an automatic developing machine (hereinafter referred to as an automatic developing machine) or the like to sequentially convey the processing solution between processing tanks.

In this case, an automatic developing machine has a developing section, a desilvering section, a washing or stabilizing section, and a drying section, and has means for automatically transporting the photographic light-sensitive material sequentially through the respective processing tank sections. Generally refers to a developing machine.

[0006] In the case of processing with such an automatic developing machine, a method of replenishing the processing liquid in order to keep the activity of the processing liquid in the processing tank constant has been widely adopted.

Specifically, the processing operation is performed while a replenisher is supplied from the replenishment tank into the processing tank at an appropriate time.

In this case, the replenisher itself stored in the replenishment tank is usually prepared in another place, and is usually replenished in the replenishment tank as needed. Conventionally, the following manual method has been adopted.

That is, a processing agent for a silver halide photographic light-sensitive material (hereinafter sometimes referred to as a photographic processing agent) is commercially available in powder or liquid form.
In the case of powder, it is prepared by manually dissolving it in a certain amount of water, and in the case of a liquid, it is concentrated and used to dilute it with water.

[0010] The refill tank may be installed beside the automatic machine, and it is necessary to secure a considerable space. In addition, a replenishing tank is built in the main body of the automatic developing machine in the minilab, which has been increasing rapidly in recent years. In this case, it is necessary to secure a space for the replenishing tank.

Replenishing processing agents are divided into several parts in order to obtain good and stable performance in photographic processing. For example, a replenisher for a color bleach-fixer is divided into a part of an organic ferric acid salt as an oxidizing agent and a part of a thiosulfate salt as a reducing agent. The part and the thiosulfate-containing concentrated part are mixed and used by adding a certain amount of water.

[0012] The concentrated part is put in a container such as a plastic container, and these are put together and put in an outer bag (for example, a cardboard box), and are sold as one unit.

[0013] The replenishing agent in which the above-mentioned parts are made into a kit is used after dissolving, diluting and mixing and finishing it in a fixed amount. However, the replenishing agent has the following disadvantages. First, each part agent is placed in a container. Depending on the replenishing agent, the number of part agents may be several, and the number of containers may be considerably large for one unit, requiring a large amount of space for storage and transportation. I do. For example, CPK-2 which is a processing solution for color paper
The color developing replenisher of -20QA is divided into 10 liters as one unit, the preservative-containing kit is divided into Part A, the color developing agent-containing kit is divided into Part B, and the alkaline agent is divided into Part C. Each of A, B and C is 500 ml. In a plastic container. Similarly, the bleach-fix solution is divided into three bottles with 8 liters as one unit, and the stabilizer is divided into two bottles with 10 liters as one unit. Each of these replenishers will be stored and transported in an outer box of various sizes, but the outer box is a small stable liquid of about 17 cm x 14 cm x
About 18.5 c with relatively large bleach-fix at 16.5 cm
It measures mx 30.5cm x 22.5cm, and can be stacked only with the same type of replenisher in storage, transportation or in shops, and eventually requires a lot of space.

A second drawback is the problem of disposal of empty containers. In recent years, there has been a strong demand for environmental conservation and resource saving mainly in Europe and the United States, and disposal of plastic containers has become a problem particularly in photography. Photo plastic containers are low in cost, convenient for storage and transportation, and have excellent chemical resistance, but plastic containers have little biodegradability,
If accumulated and incinerated, a large amount of carbon dioxide gas is generated, which contributes to global warming and acid rain, and users have a problem in that a large amount of plastic containers are piled up in a narrow work space. In addition, it has been pointed out that it cannot be crushed due to its high strength and the space is narrowed.

Third, the chemical is very unstable. For example, taking a color developing replenisher for color paper as an example, when preparing a color developing replenisher for color paper, a certain amount of water is put into a replenishing tank, and then a preservative-containing concentration kit A is put and stirred. Then, the color developing agent-containing concentrating kit B is charged and stirred, then the alkali agent-containing concentrating kit C is charged and stirred, and finally, water is added to finish the mixture to a certain amount. At that time, some problems are likely to occur. For example, if the stirring is insufficient, or if you forget to add water first, crystals of the color developing agent tend to precipitate, and they are accumulated in the bellows pump and are not replenished, resulting in unstable photographic performance. Or the bellows pump is damaged. Concentration kits may not be used immediately after production, but may be used one year after production,
In some cases, the color developing agent and the preservative are oxidized and the performance becomes unstable.

Color developing replenishers made from concentrate kits and powders are also known to have some problems in replenishment tanks. For example, if the replenisher is not used for a long time, crystals will adhere to the refill tank wall,
In addition, the replenisher is easily oxidized and tar is generated. In addition, depending on the storage conditions, there is a problem that components that easily crystallize in the replenisher, for example, color developing agents, etc., precipitate at low temperatures. For this reason, some manufacturers specify the replenisher storage conditions and manage them by the user. The fact is that they are teaching.

As described above, the method of preparing a replenisher using a commonly used concentrating kit or the method of preparing a replenisher using a powder can be exemplified by a color developing solution for color paper. There are the above-mentioned problems, and similar problems also occur in the bleach-fixing solution, the bleaching solution, and the fixing solution.

On the other hand, apart from the above-described method of preparing a replenisher using a concentrating kit or a powder, a method of directly replenishing a concentrating kit is known.

In this method, in order to reduce the inefficiency of the dissolving operation, the concentration kit is directly replenished to the treatment tank using a supply means such as a bellows pump, and a certain amount of water is independently replenished. is there. Certainly, this method does not require a liquid preparation operation as compared with the above-mentioned method of preparing a replenisher from a concentration kit or a powder. Alternatively, since no replenisher is prepared, the problem of storage stability is eliminated.

However, the above method also has a number of problems. That is, in order to supply the concentration kit, a tank for the concentration kit and a pump as a supply means are newly required, which causes a problem that the size of the automatic processing machine is increased. For example, taking the color paper processing solution CPK-2-20 as an example, there are three parts for the color developing replenisher kit, three parts for the bleach-fix replenisher, and three parts for the stable replenisher. The kit consists of two parts, which are supplied with 8 tanks for the concentration kit and 8 pumps
You need a unit. In the case of the conventional replenishment method, it is sufficient to provide a tank and a pump for each replenisher, so that three is sufficient. Even in the case of supplying the enrichment kit in this way, more tanks and pumps are required compared to the conventional method,
Further, a pump for conditioning water is required.

Further, in the concentration kit, crystals are easily deposited near the outlet of the replenishing nozzle because of the concentrated solution, and maintenance is difficult. Further, the bellows pump does not have such a high supply accuracy, and in the case of replenishing the concentrated liquid, the replenishment accuracy is liable to be greatly deviated, resulting in a large fluctuation in photographic performance. Another problem is that the method of supplying the waste plastic container with the enrichment kit does not change the conventional replenishment method and the amount of waste plastic container.

Some proposals have been made to eliminate the plastic container and improve the stability of chemicals by methods other than those described above.

For example, JP-A-58-11032 discloses a technique for encapsulating a developing component in microcapsules, and JP-A-51-61837 discloses a photographic tablet containing a disintegrant. . Further, JP-A-2-1090
No. 42, No. 2-109043, No. 3-39735, and No. 3-39939 disclose a method using a granulated photographic processing agent having a certain average particle size.

The photographic tablet containing a disintegrant described in JP-A-51-61837 is merely a tablet which easily dissolves in water.

Japanese Patent Application Laid-Open No. 2-109042 describes a granulated photographic processing agent having a certain average particle size.

However, these publications do not propose an automatic developing machine which satisfactorily simplifies the workability and obtains stable photographic performance in an automatic developing machine, or does not propose a compact automatic developing machine without a replenishing tank.

On the other hand, as a method of making the dissolving operation unnecessary, Japanese Patent Laid-Open Publication No. 3-11344 discloses a method of extruding a paste-like part from each unit container in an amount corresponding to the mixing ratio of the part, and extruding the extruded part. A technique for accurately adjusting and supplying the diluent to a predetermined concentration has been disclosed.However, according to this method, the dissolving operation is reduced or almost completely eliminated, but the paste-like part agent is used. It is difficult to extrude a fixed amount over a long period of time, and if the frequency of use is low, the nozzles are easily clogged, and it is difficult to maintain a constant photographic performance. In addition, a container for containing the paste is required. In this case, a material that is flexible and hard to break is required, and a composite material that is generally difficult to reuse is used, which is environmentally unfavorable.

JP-A-55-123942 discloses powders,
Although a replenisher supply device for photographic development that supplies a solution and dilution water is disclosed, there is no description about a processing agent replenishment control unit for maintaining stable photographic performance.

Japanese Utility Model Application Laid-Open No. 1-85732 discloses an automatic developing machine having a means for charging a tablet-type antibacterial agent into a stabilizing solution. Also, since the purpose is to preserve the liquid itself, this is not required.

[0030]

The third is to provide a processing system with stable photographic performance, and the fourth is to provide a low-pollution system capable of reducing or eliminating the use of plastic containers. It is to make.

It has been found that the above object can be attained by an automatic developing machine for a silver halide photographic light-sensitive material having a control means for carrying out the method.

Further, in these self-developing machines, the solid processing agent is a tablet, the solid processing agent is formed by a tableting step after granulation, and the solid processing agent is the silver halide photographic light-sensitive material. The processing tank to which all the components necessary for processing the material are contained, the processing tank to which the solid processing agent is supplied, the processing section for processing the silver halide photographic light-sensitive material, and the processing section are in communication with the processing section.

It is also a preferable embodiment that the means is provided for each of the processing tanks.

According to the present invention, the solid processing agent is supplied to the processing tank in accordance with the processing amount information of the silver halide photographic light-sensitive material, so that the dissolving operation is eliminated, the replenishment tank is eliminated, and the compactness of the automatic developing machine is achieved. Furthermore, it is possible to dramatically improve the stability of chemicals, and to reduce or eliminate the width of plastic containers.

In other words, a replenishment tank and a bellows pump for supplying a replenisher to the processing tank in order to supply the solid processing agent to the processing tank become unnecessary, and the size and cost of the automatic developing machine can be reduced. Further, by using the solid processing agent, various problems caused by the replenisher such as precipitation of crystals and generation of tar, which are unexpectedly observed in the replenisher, can be solved at once.

The solid processing agent has the advantage that the replenishing amount can be reduced as compared with the liquid, and the liquid does not scatter during the work and adhere to or contaminate the human body, clothes, and peripheral devices.

In the present invention, by providing the water replenishment means, the concentration fluctuation of the processing solution can be kept constant and the performance can be stabilized. Further, when the solid processing agent is a tablet, the replenishment accuracy is remarkably improved as compared with a method in which the replenisher is sent out by a fixed amount using a bellows pump, and the concentration control becomes easier.

The solid processing agent referred to in the present invention includes not only tablets, granules and powders, but also tablets, granules and powders packaged or covered with soluble films such as alkali-soluble films and water-soluble films. Including things. Pastes and slurries are not the solid processing agents referred to in the present invention.

The term "dust" as used herein means an aggregate of fine crystals. The term “granules” as used in the present invention refers to granules having a particle diameter of 50 to 5000 μm, which are obtained by adding a granulation step to powder. The tablet in the present invention refers to a tablet obtained by compression-molding a powder into a certain shape.

Hereinafter, the present invention will be described in detail.

Among the above solid processing agents, tablets are preferred.
It is preferably used because of high replenishment accuracy and easy handling.

To solidify the photographic processing agent, a concentrated liquid or a fine or granular photographic processing agent and a water-soluble binder are kneaded and molded, or the water-soluble binder is added to the surface of the temporarily formed photographic processing agent. Any means can be adopted, such as forming a coating tank by spraying (refer to Japanese Patent Application Nos. 2-135887 and 2-13887).

No.).

A preferred tablet production method is a method in which a powdered solid processing agent is granulated and then subjected to a tableting step to form the tablet. There is an advantage that the solubility and storage stability are improved and the photographic performance becomes stable as compared with a solid processing agent formed by a tableting step by simply mixing a solid processing agent component.

Granulation methods for tablet formation include known methods such as tumbling granulation, extrusion granulation, compression granulation, crushing granulation, stirring granulation, fluidized bed granulation, and spray drying granulation. Can be done.
For tablet formation, the resulting granulate has an average particle size of 10
It is preferable to use one having a thickness of 0 to 800 μm, more preferably 200 to 750 μm. Average particle size is 100
When the particle size is smaller than μm or larger than 800 μm, when the above granulated material is mixed and compressed under pressure, the components become non-uniform, that is, so-called segregation is not preferred. Further, the particle size distribution is preferably such that 60% or more of the granulated particles have a deviation of ± 100 to 150 μm. When the obtained granules are then compressed under pressure, a known compressor, for example, a hydraulic press,
Single tablet presses, rotary tablet presses, and pre-ketting machines can be used. The solid processing agent obtained by pressurizing and compression can take any shape, but a cylindrical type, so-called tablet, is preferable from the viewpoint of productivity and handling.

More preferably, at the time of granulation, the above-mentioned effect becomes more remarkable by separately granulating each component, for example, an alkali agent, a reducing agent, a bleaching agent, a preservative, and the like.

The method for producing a tablet processing agent is described, for example, in JP-A-51-61837, JP-A-54-155038, and JP-A-52-55038.
No. 88025, British Patent No. 1213808, etc., and can be produced by a general method. Further, granulating agents are described in, for example, JP-A Nos. 2-10942 and 2-109.
It can be produced by a general method described in the specification of JP-A Nos. 043, 3-39735 and 3-39939. Furthermore, powder processing agents are described, for example, in JP-A-54-13333.
No. 2, British Patent Nos. 725,892 and 729,862, and German Patent No. 3,733,861.

[0056] The bulk density of the solid processing agent, and in view of its solubility, when the solid processing agent from the viewpoint of the desired effect of the present invention is a tablet 1.0g / cm ³ ~2.5g / cm ³ Is preferably more than 1.0 g / cm ³ in terms of strength of the obtained solid, and less than 2.5 g / cm ³ is more preferable in terms of solubility of the obtained solid. When the solid processing agent is granules or powder, the bulk density is 0.40 to 0.95 g / cm ^3.
Are preferred.

The solid processing agents used in the present invention are used in photographic processing agents such as color developers, black-and-white developers, bleaching agents, fixing agents, bleach-fixing agents and stabilizers. The color developing agent has a large stabilizing effect.

According to the embodiment of the present invention, it is most preferable that all the processing agents are solidified, but it is preferable that at least the color developer is solidified. That is, the effects of the present invention are most remarkably exhibited since the color developing component contains a large number of components that cause a mutual chemical reaction and also contains harmful components. More preferably, in addition to the color developing agent, the bleach-fixing agent or the bleaching agent and the fixing agent are solidified.

Although it is within the scope of the present invention that the solid processing agent used in the present invention can solidify only one part of a certain processing agent, it is preferable that the solid processing agent contains all components necessary for processing the light-sensitive material. It is to contain.

The fact that the solid processing agent necessary for processing the photographic material contains all the components necessary for processing the photographic material means that all the processing agents replenished to each processing tank according to the processing amount information are subjected to solid processing. It is to be injected as an agent. If replenishing water is required, all but the replenishing water is added as a solid processing agent. In this case, the liquid to be replenished to the processing tank can be at most only the replenishing water. That is, when there are two or more types of processing tanks that need replenishment, the replenishing liquid is shared by sharing the replenishing water. Only one storage tank is required, and the size of the automatic developing machine can be reduced.

When the color developing agent is solidified, the alkali agent, the color forming agent and the reducing agent are all converted into a solid processing agent, and in the case of tablets, at least 3 or less, most preferably 1 agent is used. At least one of the agent or reducing agent
One is a preferred embodiment of the solid processing agent used in the present invention, since it is improved in workability as compared with a case where one is used as a solid processing agent and the other is used as a liquid agent, and it is possible to reduce erroneous use by a user.

When the treating agent is wrapped or bound or covered with a water-soluble film or binder, the water-soluble film or binder may be a polyvinyl alcohol-based, methylcellulose-based, polyethylene oxide-based, starch-based, polyvinylpyrrolidone-based, Hydroxypropylcellulose, pullulan, dextran and gum arabic,
Polyvinyl acetate-based, hydroxyethylcellulose-based, carboxyethylcellulose-based, carboxymethylhydroxyethylcellulose sodium salt-based, poly (alkyl) oxazoline-based, polyethylene glycol-based film or binder is preferably used, among these, Particularly, polyvinyl alcohol-based and pullulan-based ones are more preferably used from the viewpoint of the effect of coating or binding.

The preferred polyvinyl alcohols are very good film-forming materials and have good strength and flexibility under most conditions. Commercially available polyvinyl alcohol compositions cast as films vary in molecular weight and degree of hydrolysis, but preferably have a molecular weight of about 10,000 to about 100,000. The degree of hydrolysis is the rate at which the acetate group of polyvinyl alcohol is replaced with a hydroxyl group. For film applications, the range of hydrolysis is usually from about 70% to 100%. Thus, the term polyvinyl alcohol usually includes polyvinyl acetate compounds.

The method for producing these water-soluble films is described, for example, in JP-A-2-124945 and JP-A-61-9934.

Come up.

The water-soluble film is preferably thermoplastic. This is because not only the heat sealing process and the ultrasonic welding process are facilitated, but also the covering effect is more excellent.

Also, photographic processing agents packaged or bound or coated with a water-soluble film or binder can be used during storage, transportation and handling to prevent atmospheric humidity such as high humidity, rain and fog, and water. It is preferable that the moisture-proof packaging material has a film thickness of 10 to 15 in order to prevent damage from sudden contact with water due to splashing or wet hands.
0 μm film is preferable, and the moisture-proof packaging material is polyethylene terephthalate, polyethylene, polyolefin film such as polypropylene, kraft paper, wax paper, moisture-resistant cellophane, glassine, polyester, polystyrene, polyvinyl chloride, which can have a moisture-proof effect with polyethylene,

The means for supplying the solid processing agent has a control means for supplying a fixed amount of the solid processing agent in accordance with the processing amount information of the photosensitive material, which is an important requirement in the present invention.
That is, in the automatic developing machine of the present invention, it is necessary to keep the component concentration in each processing tank constant and to stabilize photographic performance. What is the processing amount information of silver halide photographic light-sensitive materials?
It is a value proportional to the processing amount of the silver halide photographic light-sensitive material processed with the processing solution, the processing amount of the processed silver halide photographic light-sensitive material, or the processing amount of the silver halide photographic light-sensitive material being processed. It indicates indirectly or directly the amount of reduction of the treating agent in the liquid. The detection may be performed at any time before or after the photosensitive material is carried into the processing solution, or during immersion in the processing solution.

Next, an example of an automatic developing machine to which the present invention can be applied (hereinafter simply referred to as an automatic developing machine) will be described with reference to the drawings. FIG. 1 is a schematic diagram of a printer processor in which a self-developing machine A and a photographic printer B are integrally configured.

In the figure, at the lower left of the photoprinting apparatus B,
A magazine M in which photographic paper, which is an unexposed silver halide photographic material, is stored in a roll shape is set. The photographic paper pulled out of the magazine is cut into a predetermined size via the feed roller R and the cutter unit C, and becomes a sheet-like photographic paper. This sheet-shaped photographic paper is transported by the belt transport means B, and the image of the original O is exposed at the exposure section E. The exposed sheet-shaped photographic paper is further conveyed by a plurality of pairs of feed rollers R and introduced into the automatic developing machine A. In the automatic developing machine A, the sheet-shaped photographic paper is transported by roller transport means (consisting substantially of three tanks) in the color developing tank 1A, the bleach-fixing tank 1B, and the stabilizing tanks 1C, 1D, and 1E, which are processing tanks. The sheets are sequentially conveyed according to the symbol No, and undergo color development processing, bleach-fix processing, and stabilization processing, respectively. The sheet-shaped photographic paper subjected to each of the above processes is dried in the drying unit 35 and discharged outside the machine.

The dashed line in the figure indicates the transport route of the silver halide photographic light-sensitive material. Further, in the embodiments, the photosensitive material is guided into the automatic processing machine A in a cut state, but may be guided into the automatic processing machine in a belt shape. In this case, if an accumulator for temporarily storing the photosensitive material is provided between the automatic developing machine A and the photographic printing machine B, the processing efficiency is increased. Further, it goes without saying that the self-developing machine according to the present invention may be configured integrally with the photoprinting machine B, or may be a single self-developing machine. Further, the silver halide photographic light-sensitive material processed by the self-developing machine according to the present invention is not limited to an exposed photographic paper, but may be an exposed negative film or the like. Further, as an explanation of the present invention, an automatic developing machine having a substantially three-tank configuration having a color developing tank, a bleach-fixing tank, and a stabilizing tank will be described. However, the present invention is not limited thereto. The present invention can be applied to an automatic developing machine having a substantially four-tank configuration having a tank and a stabilizing tank.

FIG. 2 is a schematic view of a color developing tank 1A which is a processing tank in the II section of the automatic processing machine A of FIG. The bleach-fixing tank 1B and the stabilizing tanks 1C, 1D, and 1E have the same configuration as the color developing tank 1A. Therefore, when the processing tank 1 is described below, the color developing tank 1A, the bleach-fixing tank 1B, and the stable The tanks 1C, 1D, and 1E are all referred to. It should be noted that, in the figure, a conveying means for conveying the photosensitive material is omitted for easy understanding of the configuration. In this example, a case where the tablet 13 is used as the solid processing agent will be described.

The processing tank 1 has a processing section 2 for processing a photosensitive material.
And a solid processing agent receiving portion 11 for supplying a tablet 13 integrally provided outside a partition wall forming the processing portion.
The processing section 2 and the solid processing agent receiving section 11 are partitioned by a partition wall 12 formed with a communication window, so that the processing liquid can be circulated.

The cylindrical filter 3 is provided under the solid processing agent receiving portion 11 so as to be exchangeable, so that insoluble matter in the processing solution,
For example, it has a function of removing paper waste and the like. The inside of the filter 3 communicates with the suction side of a circulation pump 5 (circulation means) through a circulation pipe 4 provided through the lower wall of the solid processing agent receiving portion 11.

The circulation system is constituted by a circulation pipe 4 forming a circulation path for the liquid, a circulation pump 5, a treatment tank 1, and the like. The other end of the circulation pipe 4 communicating with the discharge side of the circulation pump 5 penetrates a lower wall of the processing unit 2 and communicates with the processing unit 2. With such a configuration, when the circulating pump 5 is operated, the processing liquid is sucked from the solid processing agent receiving section 11, discharged to the processing section, mixed with the processing liquid in the processing section 2, and again received the solid processing agent. The circulation entering the unit 11 will be repeated. The flow rate of this circulating flow is
It is preferable that the flow rate is 0.5 rotation or more (rotation = circulation amount / tank capacity) with respect to the tank capacity per minute,
More preferably, it is 0.75 to 2.0 rotations. This is because if the circulating flow rate is too large, the liquid surface may wave and the processing liquid may leak out of the processing tank 1. In addition, a large circulation pump 5 must be used.
Further, the circulation direction of the processing liquid does not need to be limited to the direction shown in FIG. 2 and may be the opposite direction.

The waste liquid pipe 6 serves to overflow the processing liquid in the processing section 2 and keeps the liquid level at a constant level. It helps prevent the components leaching from the photosensitive material from accumulating and increasing.

The rod-shaped heater 7 has a solid processing agent receiving portion 11.
Is disposed so as to be immersed in the processing liquid in the solid processing agent receiving portion 11 by penetrating the upper wall of the solid processing agent. The heater 7 heats the processing liquid in the solid processing agent receiving section 11 and the processing tank 1, in other words, the processing liquid in the processing section 2, the solid processing agent receiving section 11 and the processing tank 1 is processed. This is a temperature adjusting means for maintaining the temperature in a suitable temperature range (for example, 25 to 55 ° C.).

The processing amount information detecting means 8 is provided at the entrance of the automatic processing machine and is used for detecting the processing amount of the photosensitive material to be processed. The processing amount information detecting means 8 includes a plurality of detecting members arranged in the left-right direction, and functions as an element for detecting the width of the photosensitive material and counting the detected time. Since the conveying speed of the photosensitive material is mechanically set in advance, the processing area of the photosensitive material can be calculated from the width information and the time information. The processing amount information detecting means may be any means that can detect the width and the transport time of the photosensitive material, such as an infrared sensor, a microswitch, and an ultrasonic sensor. In addition, in the case where the processing area of the photosensitive material can be indirectly detected, for example, in the case of a printer processor as shown in FIG. 1, the amount of the photosensitive material subjected to printing, or
The number of processed photosensitive materials having a predetermined area may be detected. Further, the detection timing is before the processing in this example, but may be after the processing or during the immersion in the processing liquid (in such a case, the position where the processing amount information detecting means 8 is provided). Can be appropriately changed to a position that can be detected after processing or a position that can be detected during processing). Furthermore, as information to be detected, in the above description, the processing area of the photosensitive material has been described.
The present invention is not limited to this, and may be any value that is proportional to the processing amount of the photosensitive material to be processed, processed, or being processed. There may be. Further, it is not necessary to provide the processing amount information detecting means 8 for each of the processing tanks 1A, 1B, 1C, 1D, 1E, but it is preferable to provide one for one automatic processing machine.

The treatment agent supply means 17 is disposed above a filtration means 14 to be described later, and has a cartridge 15 enclosing the tablet 13 as a solid treatment agent and an extruding member 10 for extruding one or more tablets 13. And The processing agent supply unit 17 is controlled by a processing agent supply control unit 9 described later, and pushes out the waiting tablet 13 with the extruding member 10 in conjunction with a supply signal issued from the processing agent supply control unit 9. The tablets 13 are supplied to a filtration unit 14 in the solid processing agent receiving unit 11. In the present invention, the solid processing agent 13 ′ is supplied to the filtration unit 14 in the solid processing agent receiving unit 11. However, the solid processing agent 13 ′ may be supplied anywhere in the processing tank 1. In the present invention, it is necessary only that the solid processing agent can be dissolved using the processing liquid, and it is necessary to ensure that the components corresponding to the processing amount information of the photosensitive material are charged and that the processing characteristics of the processing liquid in the processing tank 1 be kept constant. However, more preferably, the solid processing agent is supplied in the circulation path of the processing liquid. The processing agent supply means 17 is configured to prevent the inside of the processing tank of the automatic processing machine, the humidity of the outside air, and the scattered processing liquid from coming into contact with the solid processing agent before being supplied to the processing tank.

Things. This filtering means 14 is processed with resin. It is not essential that the filtering means is provided in the solid processing agent receiving portion 11, and the tablets 13 supplied by the processing agent supply means 17 are used to transport the photosensitive material shown in FIG.
What is necessary is just to prevent it from mixing into the processing liquid in the processing unit 2.

The processing agent supply control means 9 controls the processing agent supply means 17, and the processing amount information (processing area in this embodiment) of the photosensitive material detected by the processing amount information detecting means 8 is a predetermined value. When a certain value is reached, the processing agent supply means 17

Next, the operation of the present invention will be described with reference to FIG. Processing amount information of the exposed photosensitive material is detected by the processing amount information detecting means 8 at the entrance of the automatic developing machine A. The processing agent supply control unit 9 supplies a processing signal to the processing agent supply unit 17 when the accumulation of the area of the photosensitive material to be processed reaches a predetermined area in accordance with the processing amount information detected by the processing amount information detecting unit 8. Emits. Upon receiving the supply signal, the processing agent supply unit 17 extrudes the tablet 13 with the pushing member 10 and supplies the tablet 13 to the filtering unit 14 in the solid processing agent receiving unit 11. The supplied tablet 13 is dissolved by the processing liquid in the solid processing agent receiving section 11, and is circulated by the solid processing agent receiving section 11 → circulating pump 5 → processing section 2 → communication window → solid processing agent receiving section 11. Dissolution is promoted by the circulating treatment liquid. On the other hand, the detected photosensitive material is sequentially conveyed in the color developing tank 1A, the bleach-fixing tank 1B, and the stabilizing tanks 1C, 1D, and 1E by roller conveying means (see the automatic developing machine A in FIG. 1). Note that the processing agent supply means 17 may be provided in each of the color developing tank 1A, the bleach-fixing tank 1B, and the stabilizing tanks 1C, 1D, and 1E, which are processing tanks, and may be supplied simultaneously.
Further, the timings of supply by the respective supply means may be different from each other, and a predetermined area for controlling the treatment agent supply means by the treatment agent supply control means 9 is equal to each processing tank 1A, 1B. , 1C, 1D, and 1E may be the same, but needless to say that they may be different.

Next, another example of the present invention will be described. Before that, not only in this example but also in the example described below, the bleach-fixing tank 1B and the stabilizing tanks 1C, 1D, and 1E have the same configuration as the color developing tank 1A, and will be described below as the processing tank 1. In this case, the color developing tank 1A, the bleach-fix tank 1B, and the stabilizing tanks 1C, 1D, and 1E are all referred to, and those having the same functions as those in FIG. Here, the description thereof is omitted, and in order to make the configuration easy to understand, a transport unit for transporting the photosensitive material is omitted.

As described above, according to the present invention, the replenishment tank which was conventionally required becomes unnecessary and the space for the replenishment tank is not required, so that the automatic processing machine becomes compact, and the solid processing agent is stored in the processing tank. Since the liquid is supplied, there is no need for liquid preparation work, there is no liquid splashing at the time of liquid preparation, and there is no attachment or contamination to the human body, clothes, or peripheral equipment, and handling is easy.
The replenishment accuracy of the processing solution is increased, and the replenished processing components are not deteriorated and have stable processing characteristics.

FIG. 4 is a schematic top view showing the self-developing machine A of FIG. 1 from the top (however, the path of the water replenishing means is described for the sake of explanation). FIG. 5 is a block diagram related to control according to the present example. Note that FIGS. 3 and 4 show a refill tank 103 for storing replenishment water. In this example, a case where the tablet 13 is used as the solid processing agent will be described.

First, portions different from FIG. 2 in FIGS. 3 and 4 will be described.

The attenuation detecting means 23 is a liquid level sensor, for example, a float switch or an electrode switch, for detecting a decrease in the level of the processing liquid contained in the processing section 2, and evaporates the processing liquid and takes out the photosensitive material. Thus, a decrease in the processing liquid is detected. Note that the attenuation detecting means 23 is not limited to the liquid level sensor, and may be any device that directly or indirectly detects that the volume of the processing liquid in the processing tank 1 has decreased from a predetermined amount.

The replenishment water supply means 102 is a means for replenishing replenishment water (replenishment water) from the replenishment tank 103 for storing replenishment water to the treatment agent supply part 11, and includes a hot water replenishing device 32 including a pump, a temperature controller and the like. , A solenoid valve 33 and a water refill pipe 36. This replenishing water supply means 102

For this reason, water replenishment may be performed, but water replenishment in such a case is particularly useful. The replenishing water supply means 102 may be separately provided with a means for replenishing water in the case described above, but it is preferable that the means also serve as the means. Also,
The replenishing water supply means in the case of (1) is not limited to replenishing water in accordance with the processing amount information detected by the processing amount information detecting means 8, but replenishing water in accordance with the information that the processing agent has been supplied by the processing agent supplying means 17. It goes without saying that this may be done.
A rehydration tank or a rehydration pump may be provided for each of the treatment tanks 1A, 1B, 1C, 1D, and 1E. When this is done, the autogenous machine becomes compact, and more preferably, only one rehydration tank and rehydration pump are provided in the autogenous machine, and a solenoid valve is provided in the path (pipe, etc.) for rehydration so that each processing tank can be used when necessary. So that the required amount is replenished,
Alternatively, by adjusting the diameter of the water refilling pipe to increase or decrease the replenishing amount, only one water refilling tank and water refilling pump can be provided in the automatic developing machine, and the apparatus becomes more compact. In addition, for the stabilizing tanks 1C and 1D, which are processing tanks, respectively, by supplying the overflowing stabilizing liquid from the stabilizing tanks 1D and 1E, the replenishing water supply means can be omitted. Further, it is preferable that the temperature of the replenishing water in the water refilling tank is controlled.

The water to be replenished is not only general water such as well water or tap water, but also contains a fungicide such as an isothiazoline-based compound and a chlorine releasing compound, and a slight sulfite chelating agent. And the like having no influence on the photographic performance, such as those containing the same.

As the treatment agent supply control means 9, a replenishment water supply control means is provided in addition to the treatment agent supply control means of the above-described example. The replenishment water control means controls the replenishment water supply means when the attenuation detection means 23 detects a decrease in the level of the treatment liquid contained in the processing section 2 and / or the processing amount information detection means 8 Is a control means for controlling the replenishment water supply means in accordance with the processing amount information detected by. The replenishment water supply control means is provided with a processing amount information detection means 8.
Not only according to the processing amount information detected by
The control may be performed according to information that the processing agent has been supplied by the processing agent supply unit 17.

The functions and the like of FIG. 3 and FIG. 2 other than the above are the same as those in FIG.
It will be described.

The heater 7 is arranged at the bottom of the processing section 2 and heats the processing liquid in the processing section 2. In other words, the heater 7 heats the processing liquid in the processing section 2 and the solid processing agent receiving section 11. It performs a temperature control function of maintaining a temperature range suitable for processing (for example, 25 to 55 ° C.).

As a circulating means, a circulating pipe 4 and a circulating pump 5 are provided in the same manner as in FIG. 2, but the difference from FIG. 2 is that the processing liquid circulates in the opposite direction. Part 2 → circulation pump 5 → solid processing agent receiving part 11
→ circulate through the communication window → processing unit 2.

The processing agent supply means 17 includes a cartridge 15
Press the tablet 13 which is a solidifying agent enclosed in the nail 1
By 8, it is supplied to the filtering means 14 in the solid processing agent receiving section 11. 2 differs from FIG. 2 in that the cam 19 is actuated by a single rotation stop mechanism to actuate the push claw 18,
The tablet 13 that has been on standby is supplied to the processing tank 1, and the next tablet 13 is urged downward from above by the tablet pressing spring 26, so that the tablet 13 immediately enters the standby state. At this time, the processing agent supply unit 17 may be of a horizontal type or a push-up type from below, and in short, any means capable of charging the solid processing agent into the processing tank 1 may be used.

Next, the operation of the present invention will be described with reference to FIGS. 1, 3, 4 and 5. Processing amount information of the exposed photosensitive material is detected by the processing amount information detecting means 8 at the entrance of the automatic developing machine A. The processing agent supply control means 9 includes:
When the accumulation of the area of the photosensitive material to be processed reaches a predetermined area according to the processing amount information detected by the processing amount information detecting unit 8, a supply signal is issued to the processing agent supply unit 17.

To the filtration unit 14 in the inside. The supplied tablet 13 is dissolved by the processing liquid in the solid processing agent receiving section 11, but is circulated by the circulating means to the processing section 2 → circulation pump 5 → solid processing agent receiving section 11 → communication window → processing section 2 Dissolution is promoted by the treatment solution that is present. On the other hand, according to the processing amount information detected by the processing amount information detecting means 8, the replenishing water supply controlling means, when the accumulated area of the photosensitive material to be processed reaches a predetermined area, replenishing water supplying means 102 (hot water A rehydration signal is issued to the supply device 32 and the solenoid valve 33). Upon receiving the rehydration signal, the replenishment water supply means 102 controls the hot water replenishment device 32 and the solenoid valve 33 to supply the replenishment water stored in the rehydration tank 103 to each treatment tank or a required treatment tank by a predetermined amount. Or replenish the required amount of water. The predetermined area in this case is the same amount as that in the processing agent supply control means 9, but is not limited thereto, and may be different predetermined areas.

The sheet is sequentially conveyed in E by roller conveying means. further,
When the attenuation detecting unit 23 detects a decrease in the processing liquid due to the evaporation of the processing liquid or the removal of the photosensitive material, the signal is input to the replenishment water supply control unit. The supplied replenishment water supply control means issues a rehydration signal to the replenishment water supply means, and controls the replenishment water supply means to perform replenishment until the treatment liquid is filled to a predetermined liquid level.

In this description, the replenishment water supply means is provided, but only the replenishment means or only the replenishment water supply means may be provided. If only the attenuation water replenishing means is provided, the processing liquid in the processing tank is maintained at a predetermined temperature, so that the processing liquid evaporates while the automatic processing machine is operating or stopped, or the photosensitive material is Since the photosensitive material takes out the processing liquid when transported to the tank, the processing liquid has an effect of preventing the processing liquid from dropping below a predetermined amount and fluctuating the processing liquid characteristics. When only the replenishing water supply means is provided, the dissolution of the solid processing agent supplied in the processing solution is promoted, the concentration of the processing solution is corrected, the performance of the processing solution is kept constant, and the solid processing agent is supplied. Large fluctuations in processing solution concentration due to supply can be avoided, and stable processing solution performance can be maintained at all times.Furthermore, components that have been brought into the photosensitive material or leached from the photosensitive material are stored. This has the effect that the overflow required to prevent an increase can be facilitated. Further, when both replenishing water supply means are provided, the above-described respective effects are provided, and the processing characteristics of the photosensitive material are stabilized as a self-developing machine.
Furthermore, since the water replenishment means for attenuation and the water replenishment means can be used in common, and one water replenishment tank can be used, the effect that the self-developing machine becomes more compact can be obtained.

[Table 6]

[0270]

[Table 7]

From the results shown in Tables 6 and 7, it can be seen that the processing of the present invention is more stable than the processing of the conventional method, because the photographic performance and the composition of the processing solution are small.

Example 4 In addition to the color developing replenisher 1) for color negative prepared in Example 1 and the color developing replenisher 5) for color paper, the following replenishers were prepared.

8) Color developing replenisher for color negative hydroxyamine sulfate 3.0 g, CD-4 [4 amino-

[0281]

[Table 9]

As is clear from the results of Tables 8 and 9, it is found that the tableting after granulation in the present invention has higher storage stability. In addition, it was found that it is more preferable to perform tableting after fractionation and granulation as in the case of the present inventions 1) and 5), because the preservability is higher and more preferable.

The solubility was also observed, but 1) and 5) showed the fastest dissolution, followed by 9) and 11). From this, it can also be said that when granulation is performed separately after granulation, it is preferable in terms of solubility.

Example 5 A solid processing composition was prepared in the same manner as in 5) except that diethylhydroxylamine oxalate as the color developing replenisher for color paper of Example 1 was replaced with the equivalent mole of the compound shown in Table 10. This solid processing agent is put in a glass bottle, sealed and sealed at 80 ° C for 2 hours.
After preservation for a month, the content of the preservative was measured, and the residual ratio was determined with the performance before storage taken as 100. For comparison, a solution prepared by dissolving the solid processing agent in the same manner as in Example 1 and using the solution was used.

Further, the strength of the solid processing agent after storage was increased to a height of 50%.
