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 (hereinafter sometimes referred to simply as "developing machine"). The present invention relates to an automatic developing machine which has a significantly improved workability and which dramatically improves chemical stability.

[0002]

2. Description of the Related Art Silver halide color photographic light-sensitive materials (hereinafter sometimes referred to as light-sensitive materials or photographic materials) are
After the exposure, it is processed by steps such as development, desilvering, washing and stabilization. The black-and-white silver halide photographic light-sensitive material is developed and fixed after exposure. Black-and-white developer, color developer, bleaching solution for desilvering process, bleach-fixing solution, fixing solution for fixing process, tap water or ion-exchanged water for washing, stabilizing solution for anhydrous washing, and dye stabilization Stabilizers are used for each treatment.

A liquid having a processing function for performing each of these processing steps is called a processing liquid. Each treatment liquid is usually 30 ~
The temperature is adjusted to 40 ° C., and the light-sensitive material is dipped in these processing solutions and processed.

Such processing is usually carried out by sequentially conveying the inside of a processing tank containing the above processing liquid by an automatic developing machine (hereinafter referred to as an automatic processor) or the like.

When referred to as an automatic developing machine, it has a developing section, a fixing section, a desilvering section, a washing or stabilizing section, and a drying section, and each processing tank section automatically conveys the photographic light-sensitive material. It generally refers to a developing machine having means.

In the case of processing with such an automatic developing machine, a method of replenishing the processing agent is generally widely used in order to keep the activity of the processing solution in the processing tank constant.

As a method for replenishing the treating agent, a method of preparing a replenishing solution in which the treating agent is dissolved is widely used.

[0008] Specifically, the replenishing solution prepared in advance is supplied from the replenishing tank to the processing tank at appropriate time to perform the processing operation.

In this case, the replenishing liquid itself stored in the replenishing tank is generally prepared and prepared in another place, but in a minilab or the like, the replenishing tank is installed in a constant amount in a replenishing tank installed close to the developing machine. It is usually adjusted all at once, but in its production, dissolution by hand or dissolution and mixing by a mixer has been performed.

That is, a processing agent for silver halide photographic light-sensitive materials (hereinafter sometimes referred to as a photographic processing agent) is commercially available in the form of powder or liquid.
In the case of a powder, it is prepared by manually dissolving it in a fixed amount of water, and in the case of a liquid, it is concentrated so that a fixed amount of water is added and the mixture is simply stirred and diluted before use.

The replenishment tank may be installed beside the automatic processing machine, and it is necessary to secure a considerable space. In addition, even in the minilab, which has been increasing rapidly in recent years, a replenishment tank is built into the machine itself, but at least 5L-10
It is necessary for each of the L liquids, and it is necessary to secure such a space for the replenishment tank.

Replenishing processing agents are divided into several parts in order to obtain good and stable performance during photographic processing. The color developing solution for color is divided into 3 to 4 parts, and the replenisher for the bleach-fixing solution for color is divided into a ferric salt of organic acid which is an oxidizing agent and a thiosulfuric acid part which is a reducing agent. When the replenisher is prepared, the concentrated part of the ferric organic acid salt and the concentrated part containing thiosulfate are mixed and a certain amount of water is added for use.

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

First, most of the conventional kits are concentrated and concentrated aqueous solutions for improving workability, and most of them are extremely dangerous aqueous solutions with a pH of 2.0 or less or 12.0 or more. Many of them are very dangerous and are often strong oxidizers or reducing agents, and they have extremely dangerous corrosiveness when transported by ship or aircraft. Further, since it is an aqueous solution, its solubility is limited, and its weight and volume are larger than those of a solid. As mentioned above, since the concentrate is a dangerous substance, it is necessary that the container does not break even if dropped from a certain height and the liquid does not spill. Is a problem.

Secondly, each part agent is placed in a container,
Depending on the replenishment processing agent, the number of part agents is several, and the number of containers is considerably large when it becomes one unit, which requires a lot of space for storage and transportation. For example, the color developing replenisher for CPK-2-20QA, which is a processing solution for color paper, is 10
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 with 1 as 1 unit, and each of A, B and C is contained in a 500 ml poly container. Similarly, the bleach-fixing solution has 8 l as a unit, and the parting agent is divided into 3 bottles, and the stabilizing solution has 10 l as a unit, and the parting agent is divided into 2 bottles. Each of these replenishers will be stored and transported in outer boxes of various sizes, but a stabilizing solution with a small outer box measures about 17 cm x 14 cm.
It is a relatively large bleach-fixing agent with a size of 16.5 cm x 18.5 cm x 30.5 cm
It becomes × 22.5cm, and it can be stacked only with the same kind of replenisher on storage, transportation or in a store, and eventually it requires a lot of space.

The third drawback is the 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 the disposal of plastic containers has become a problem especially in the photographic field. Although the plastic container for photography is cheap and convenient for storage and transportation and has excellent chemical resistance, the plastic container has little biodegradability,
When accumulated and incinerated, a large amount of carbon dioxide gas is generated, which is one of the causes of global warming and acid rain. Also, as a user's problem, a large number of plastic containers are piled up in a narrow work space. However, it has been pointed out that it cannot be crushed due to its strength, and the space is narrowed.

Fourth, the chemical is very unstable.

The life of the replenisher is usually 2 weeks even with the floating lid. However, recently, the replenishment amount of each processing solution has been lowered, and 10 L of the replenishing solution is often used for more than one month in a minilab that receives an average of 30 color films per day.

In such a case, the replenishing solution in the replenishing tank is much more exposed to air than the treating solution in the processing tank and is deteriorated. is happening. Therefore, 5L refill tank
The device is designed to be small and the storage unit of the replenishment kit is set to 5 L. In this case, there is a drawback that a packaging material is further required.

In addition, taking the color developing replenisher for color paper as an example, when a color developing replenisher for color paper is prepared, a certain amount of water is put into a replenishing tank, and then a preservative-containing concentration kit A is prepared. Then, the color developing agent-containing concentration kit B is added and stirred, and then the alkali agent-containing concentration kit C is added and stirred, and finally water is added to complete a certain amount. At that time, some problems are likely to occur. For example, if the stirring is insufficient or if the first water is forgotten to be added, crystals of the color developing agent tend to precipitate, which accumulates in the bellows pump and is not replenished, resulting in unstable photographic performance. Or the bellows pump may be damaged. Further, the concentration kit may not be used immediately after the production, but may be used one year after the production, and in some cases, the color developing agent or preservative may be oxidized and the performance may become unstable.

It is known that the color developing replenisher prepared from the concentration kit or the powder also has some problems in the replenishing tank. For example, if the replenisher is not used for a long period of time, crystals may adhere to the wall of the refill tank,
In addition, the replenisher may be easily oxidized and tar may be generated. In addition, depending on the storage conditions, there is a problem that components that easily crystallize in the replenisher, such as color developing agents, will precipitate at low temperatures.Therefore, depending on the manufacturer, the storage conditions of the replenisher may be specified and managed by the user. It is the actual situation that I am instructing.

As described above, the method for preparing a replenishing solution using a commonly used concentration kit or the method for preparing a replenishing solution using a dusting agent is exemplified by a color developing solution for color paper. There are the above-mentioned problems, and there are similar problems with bleach-fixing solutions, bleaching solutions and fixing solutions. For example, the bleach-fixing solution has a characteristic that storage stability is extremely poor. Because the bleach-fixing process is a process immediately after a color developing solution having a high pH, and since this alkaline color-fixing solution is usually brought in by the paper to be processed, the acidity is high and the pH is extremely low for the purpose of neutralization. Is customary. At a low pH, it is said that a bleach-fix solution composed of thiosulfate and an oxidizer has a markedly poor storability and a replenisher is prepared to make low replenishment impossible. In addition to this, the same applies to the fixing solution and the stabilizing solution.

Another problem is that the replenisher is only thickened while the replenisher is being made lower and faster, and the recent replenisher is usually concentrated to the solubility limit.

[0025] This means that the retentive solution is not only storable but also has many practical problems such as crystal precipitation.

On the other hand, in addition to the method of preparing a replenisher using the concentration kit or powder as described above, a method of directly replenishing the concentration kit is known.

In this method, in order to improve the inefficiency of the dissolving work, the concentration kit is directly replenished in the treatment tank by using a supplying means such as a bellows pump, and a certain amount of replenishing water is independently supplied. is there. Certainly, this method does not require a liquid preparation operation as compared with the method of adjusting the replenisher solution from the above-mentioned concentration kit or powder. Alternatively, since a replenisher is not prepared, the problem of storability is eliminated.

However, the above method also has many 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 is a problem that the automatic developing machine becomes large. For example, taking CPK-2-20 which is a processing solution for color paper as an example, there are 3 parts of a color development replenisher replenisher concentration kit, a bleach-fix replenisher replenisher concentration kit 3 parts, and a stable replenisher concentration The kit is in 2 parts, and when it is supplied, there are 8 tanks for the concentration kit and 8 pumps.
I need a stand. In the case of the conventional replenishment system, it is sufficient to have a tank and a pump for each replenisher, so that three replenishers are sufficient. Looking only at the case of supplying the concentration kit like this, more tanks and pumps are required than the conventional method,
Furthermore, a pump for adjusted water is also required. Further, the accuracy of the bellows pump is not so high, and it is difficult to simultaneously discharge a plurality of liquids with high accuracy, and there is a drawback that the components are crumpled.

Furthermore, since the concentration kit is a concentrated liquid, crystals are likely to precipitate near the outlet of the replenishing nozzle, which makes maintenance difficult. Further, there is a problem that the bellows pump does not have such a high supply accuracy, and when replenishing the concentrated liquid, the replenishment accuracy is likely to be significantly different, resulting in a large variation in photographic performance. As another problem, the conventional replenishment method and the amount of the waste poly container do not change even if the waste poly container is provided with the concentration kit.

Several methods have been proposed to eliminate the plastic container and improve the chemical stability of the replenisher by methods other than the above.

For example, Japanese Patent Application Laid-Open No. 58-11032 discloses a technique of encapsulating a developing component in microcapsules, and Japanese Patent Application Laid-Open No. 51-51.
-61837 discloses a photographic tablet containing a disintegrant. Furthermore, JP-A Nos. 2-109042 and 2-109043,
3-39735 and 3-39739 disclose a method of using a granulated photographic processing agent having a certain average particle diameter.

The photographic tablet containing the disintegrant described in JP-A No. 51-61837 is merely a tablet that can be easily dissolved in water, and the solid processing agent is directly added to the processing tank of the present invention. The idea of dissolution cannot be recalled at all.

Further, JP-A-2-09042 describes a granulated photographic processing agent having a certain average particle size.

However, the above-mentioned publication proposes an automatic developing machine in which the work of dissolving the replenisher is eliminated to simplify the workability and obtain stable photographic performance, or the replenishing tank is eliminated to provide a compact automatic processor. is not.

On the other hand, as a method for eliminating the need for a prior dissolution operation, Japanese Patent Laid-Open No. 3-11344 discloses extruding a paste-like part agent from each unit container in an amount corresponding to the mixing ratio of the part agent, Although a technology for accurately adjusting and supplying the part agent by diluting it to a predetermined concentration is disclosed, this method surely reduces the dissolution work or almost eliminates the dissolution work, but it is a paste form. Since the part agent contains a solvent, it lacks stability, and it is difficult to extrude a certain amount for a long period of time. If the part agent is not used frequently, the nozzle tends to be clogged, and it is difficult to keep the photographic performance constant. Further, a container for containing the paste is required, and in this case, a flexible and hard-to-break material is required, and a composite material that is generally difficult to reuse is used, which is not environmentally friendly. In particular, it is known that pasty chemicals are often formed into a paste by an organic solvent and have poor storage stability.

Further, Japanese Utility Model Laid-Open No. 1-85732 discloses an automatic processor having a means for supplying a tablet type antibacterial agent to a stabilizing solution. Since there is no particular problem, the supply control is unnecessary, and this does not remind the treating agent replenishment control means.
This is not mandatory because the purpose is to preserve the liquid itself.

WO 91-07698 and WO 91-07699 disclose a method in which CD-3 or CD-4 is added as a solid and other components are added as an activator in a liquid form. Is related to regeneration, and is an invention relating to low replenishment, which is as close as possible to no overflow, and after removing bromide ions and chloride ions from the developer by an ion exchange resin, the alkali agent activator and solid or small amount of the insufficient component are removed. It is a method for adding a concentrated color developing agent and adding components without increasing the volume. Further, Japanese Patent Laid-Open No. 4-213454 describes that a powdery treating agent is directly supplied to an auxiliary tank of an automatic developing machine.
However, there is no description about the feeding time when feeding the powdery treatment agent after measuring it. When the solid processing agent is directly supplied to the processing tank, most of the components of the solid processing agent are materials having high hygroscopicity, and the moisture-proof function as a supply device is important. In the above-mentioned JP-A-4-213454,
Although it is described that a means for adding a moistureproof function and providing a dehumidifying space is taken, detailed concrete means are not explained, and in general, most treatment tanks have a temperature regulated at a constant temperature between 30 and 40 ° C. However, since the upper part of the processing tank is in a considerably high humidity state, there is a problem that the solid processing agent absorbs moisture near the supply port of the solid processing agent. In other words, it is effective to provide the dehumidifying space by the dehumidifying function, but it can be said that it is meaningless unless the problem of humidity around the supply port of the solid processing agent is solved.

The problem when the solid processing agent absorbs moisture in the vicinity of the supply port is that the processing agent which has already absorbed moisture solidifies over time, and in the worst case, the supply port is covered with a solidified product and the solid processing agent cannot be supplied. That is, the accuracy of the supply port is significantly deteriorated. Unlike the conventional replenisher solution method, in the case of the solid treatment agent, since the replenishment water has a separate supply means, the supply balance between the replenishment water and the solid treatment agent may change, or at worst, only water may be replenished. It goes without saying that the performance is significantly deteriorated. Further, the solid processing agent that has absorbed moisture and becomes a liquid enters the operating portion of the supply device and is solidified, so that an excessive load is applied during operation, which may cause a failure of the supply device.

Therefore, the user has to increase the maintenance work for removing such a solidified product, and the merit of using the solid processing agent is halved.

[0040]

SUMMARY OF THE INVENTION The first object of the present invention is to:
In addition, it is to achieve the practical application of an automatic developing machine that eliminates liquid chemicals that pose transport and handling hazards and enables solid chemicals to be used without complicated operations for users.

Secondly, in order to achieve an automatic developing machine, a completely automated replenishment system capable of reliably supplying a solid processing agent to a predetermined processing tank by eliminating the dissolution work of the concentration kit by the user himself has been achieved. is there.

Thirdly, there is the achievement of a compact automatic developing machine by eliminating many built-in replenishing tanks.

The fourth object is to achieve an automatic developing system which has improved processing stability and eliminates the need for storing a liquid replenisher.

Fifth, it is to achieve a low pollution system in which the use of plastic bottles for liquids is eliminated and the use of plastic packaging materials is reduced.

[0045]

In order to solve the above problems, the present inventors have found that the above problems can be solved and achieved by the following constitution.

The above object is to set a processing tank for containing a processing solution for processing an exposed silver halide photosensitive material, a storage means for storing a solid processing agent, and / or a storage packaging material for storing the solid processing agent. Fixing means, measuring means for measuring the amount of the solid processing agent, supply means for supplying the solid processing agent to the processing tank, processing amount detecting means for detecting the processing amount of the silver halide photographic light-sensitive material, After measuring the amount of the solid processing agent, it has at least one control means for controlling the supply means to supply the solid processing agent according to the processing amount of the silver halide photographic light-sensitive material detected by the detection means. This is achieved by an automatic processor for silver halide photographic processing light-sensitive material, characterized in that the supply port time of the solid processing agent supplied by one supply operation is within 30 seconds.

[0047]

The inventors of the present invention have conducted enormous experiments to supply the solid processing agent directly to the processing tank of the automatic processor, and sought a supply means for surely supplying the solid processing agent to each processing tank.

That is, the feeding operation of the solid processing agent supplied by one feeding operation after weighing the solid processing agent obtained by detecting the processing amount information is within 30 seconds, preferably within 15 seconds, and most preferably. It has been found that the above problem can be solved by setting the time within 3 seconds.

When the liquid agent is supplied using the conventional replenisher, the supply time does not have to be so strict, but rather the supply interval is important. If the supply interval is excessively long, the treatment is performed during that interval. Processing variability has occurred depending on the photosensitive material used.

However, when the solid processing agent is directly supplied to the processing tank, since the solid processing agent supplied to the processing tank does not dissolve instantly, there is a releasing effect, which is a major factor. It was surprising that the supply time was found to be the largest factor in determining supply certainty.

As a result of diligent studies and supply of various solid processing agents by various supply devices, the present inventors have found that many of the photographic solid processing agents have high hygroscopicity and have a serious problem in supplying the processing agents. To improve the moisture resistance of the treatment agent itself, coat the treatment agent with a coating agent, or provide a dehumidification space by injecting a dehumidifier or dry air into the solid processing agent supply section of the automatic processor. However, as a result of further studies, the temperature of the treatment tank is generally adjusted to 30 to 40 ° C, and the solid treatment agent supply port is directly exposed to the high-humidity atmosphere from the treatment tank. Found that they were always under high humidity conditions when supplied.

Therefore, when the solid treating agent is supplied for a long period of time after the solid treating agent is weighed (hereinafter referred to as “weighing”), a part of the solid treating agent is deliquescent at the supply port. Then, it was found that solidification started from the vicinity of the supply port with the lapse of time and the solidified product grew to cause the above-mentioned trouble.

The above facts are the same as in the case of powders, granules, tablets, pills, etc., but the smaller the particle size of one particle of the solid processing agent is, the more solidification from the vicinity of the supply port is. Found, granules are preferred in the present invention,
More preferred are tablets and pills.

The present invention will be described in more detail below.

After the measurement of the solid processing agent in the present invention, at least a part of the measured solid processing agent is separated from the solid processing agent supply device with respect to the supply time of the solid processing agent supplied by one supplying operation. The time from the time point as a starting point to the time point at which all the solid processing agents weighed finally come into contact with the liquid interface of the processing bath.

Further, the solid processing agent is in a pre-measured form such as a four-sided sealed package, a three-sided sealed package, a pillow package, a PTP package, a blister package, and the solid processing agent supply device (having a package opening function) The supply starting point when opening the package refers to the point when the package is opened.

The solid processing agent in the present invention includes the powder processing agents as described above and the solid processing agents such as tablets, pills and granules, which are optionally subjected to a moisture-proofing treatment. Pastes and slurries are not included in the solid processing composition of the present invention, except for those which are semi-liquid and have poor storage stability and are subject to regulations that pose a risk of transportation.

The powder in the present invention refers to an aggregate of fine crystal grains. The granules referred to in the present invention are obtained by adding a granulation step to powder, and are granular materials having a particle size of 50 to 5000 μm. The tablet in the present invention refers to a powder or granules compression-molded into a certain shape.

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

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 the water-soluble binding agent is formed on the surface of the temporarily molded photographic processing agent. Any means such as forming a coating layer by spraying can be adopted (Japanese Patent Application No. 2-135887, No. 2-203165,
2-203166, 2-203167, 2-203168, 2-304
See No. 09).

A preferable tablet manufacturing method is a method in which a powdery solid processing agent is granulated and then a tableting step is performed to form the tablet. There is an advantage that the solubility and storability are improved and the photographic performance becomes stable as compared with the solid processing agent formed by the tableting process by simply mixing the solid processing agent components.

As the granulation method for tablet formation, known methods such as rolling granulation, extrusion granulation, compression granulation, crushing granulation, stirring granulation, fluidized bed granulation and spray drying granulation are used. Can be done.
In order to form tablets, the average particle size of the obtained granules is 100 to 800 μm, because when the granules are mixed and compressed under pressure, non-uniformity of the components, so-called segregation does not easily occur. It is preferable to use one, more preferably 200 to 750 μm
Is. Furthermore, the particle size distribution is ± 10 for 60% or more of the granulated particles.
Those having a deviation of 0 to 150 μm are preferable. When compressing the obtained granulated product under pressure, a known compressor such as a hydraulic press, a single-shot tableting machine, a rotary tableting machine, or a preketching machine can be used. The solid processing agent obtained by compression under pressure can have any shape, but from the viewpoint of productivity, handleability, or from the problem of dust when used on the user side, a cylindrical type, a so-called tablet is used. preferable.

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.

A method for producing a tablet processing agent is described in, for example, Japanese Patent Laid-Open No.
51-61837, 54-155038, 52-88025, British patent 1
It can be produced by a general method described in the specification such as 213808, and further, the granule treating agent is, for example, JP-A-2-09042,
It can be produced by a general method described in the specifications such as 2-109043, 3-39735 and 3-39739. Further, the powder processing agent is, for example, JP-A-54-133332, British Patent 725892.
No. 729862, and German Patent No. 3738361, and the like.

The bulk density of the above-mentioned solid processing agent is a tablet in view of its solubility and the effect of the object of the present invention.
In terms of the strength of 1.0g / cm ³ ~2.5g / cm ³ is preferably 1.0 g / cm ³ greater than the resulting solid, from the viewpoint of solubility of the solid product obtained as 2.5 g / cm ³ less than preferable. When the solid processing agent is granules or powder, the bulk density is preferably 0.40 to 0.95 g / cm ³ .

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

The black and white developing agents, color developing agents, bleaching agents, bleach-fixing agents and stabilizers can be excluded from the regulation of liquid dangerous substances.

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 to solidify at least the color developing 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 harmful component, the effect of the present invention is most remarkably exhibited. More preferably, in addition to the color developing agent, the bleach-fixing agent, or the bleaching agent and the fixing agent are made into a solid processing agent. Conventionally, these are liquid packaging kits, which pose a problem of transportation risk.

It is within the scope of the present invention to solidify only a part of the components of a certain treating agent in the solid treating agent used in the present invention, but preferably all components of the treating agent are solidified. is there. It is desirable that each component be molded as a separate solid processing agent and packaged in the same manner. It is also desirable that the separate components are packaged in the order in which they are periodically and repeatedly supplied.

It is preferable to supply all the processing agents to be replenished to the respective processing tanks as solid processing agents according to the processing amount information.
When replenishment water is required, it is replenished based on the throughput information or other replenishment water control information. In this case, the liquid to be replenished in the processing tank can be only replenishing water. That is, when there are two or more types of processing tanks that need to be replenished, only one tank is required to store the replenishing liquid by sharing the replenishing water, and the automatic developing machine can be made compact. In particular, it is a preferable method to place one replenishing water tank on the outside in order to make the automatic developing machine compact.

In the present invention, when solidifying a color developing agent, all of the alkaline agent, the color developing agent and the reducing agent are treated as a solid processing agent, and in the case of a tablet, at least 3 agents or less, most preferably 1 agent is used. It is a preferred embodiment of the solid processing agent used. When two or more agents are divided into solid processing agents, it is preferable that the plurality of tablets and granules be packed in the same package.

The following materials can be used for moisture-proof packaging of tablets and pills.

Further, it is more preferable to use various gas barrier films such as using aluminum foil or aluminum vapor-deposited synthetic resin between the above synthetic resin films.

As a method for moisture-proof packaging of tablets and granules, there are 4-way seal, 3-way seal stick (pillow package, gusset package) PTP cartridge.

The four-sided seal, three-sided seal, and stick (pillow, gusset) packaging are different in the form, and the above materials are used. However, when used in the peel-open system, a sealant agent is laminated to give the peel-open suitability. .

The peel-open method generally includes a cohesive failure method, an interface peeling method, and an interlayer peeling method.

The cohesive failure method is an adhesive called hot melt, which is used as a sealant in a heat-seal lacquer, and peels off due to internal cohesive failure of the sealant layer during opening.

The surface-active peeling method is a method of peeling at the interface between films, in which the sealing film (sealant) and the adherend are not completely fused and can be peeled with an appropriate strength. The sealant is a film in which an adhesive resin is mixed, and polyethylene, polypropylene or a copolymer thereof, a polyester type, or the like can be selected depending on the material of the adherend.

Further, the delamination method is one in which the sealant is peeled between the layers of the laminate film by using a multi-layer coextrusion film such as a laminate film.

In the peel-open method using the film of the present invention, the interlayer peeling method or the interface peeling method is preferable.

Since such a sealant is thin,
Usually, other films such as polyethylene, polypropylene, polystyrene, polycarbonate, polyester (polyethylene terephthalate), polyvinyl chloride, nylon, eval, aluminum are laminated and used, but considering moisture resistance, environmental friendliness and matching with contents. Polyethylene, polypropylene, polyester, EVAL and the like are preferable. In consideration of printability, the outermost surface is preferably unstretched polypropylene polyester, paper or the like.

As a type laminated with polyester, there are Declan C-1600T, C-1602T and the like.

PTP is a packaging form in which a solid processing agent is put in a sheet of PVC, CPP or the like which is molded as a kind of blister packaging and heat sealed with an aluminum sealing material.

There is a tendency not to use PVC as a forming material for the environment, and recently A-PET or highly moisture-proof PP (for example, TAS) is used.

In the present invention, as the supply means for supplying the solid processing agent to the processing tank, for example, when the solid processing agent is a tablet, Japanese Utility Model Laid-Open Nos. 63-137783 and 63-97522,
Although there is a known method such as Japanese Utility Model Laid-Open No. 1-85732, any method may be used as long as it has at least the function of supplying tablets to the processing tank. Further, when the solid processing agent is a granule or powder, it is used in Japanese Utility Model Laid-Open Nos. 62-81964, 63-84151 and JP-A-1-
No. 292375, the gravity drop method described and No. 63-105159,
The method using screws or screws described in JP-A-63-195345 and the like is a known method, but is not limited thereto.

However, a preferable method is, as a supply means for supplying the solid processing agent to the processing tank, for example, a predetermined amount of the solid processing agent which is previously weighed and divided and packaged is opened in accordance with the processing amount of the photosensitive material, A method of taking it out is possible. Specifically, the solid processing agent is sandwiched and housed in a package composed of at least two packaging materials by a predetermined amount, preferably one replenishment amount, and the package is separated in two directions or the package A part of it is opened so that it can be taken out. The solid processing agent that can be taken out can be easily supplied to the processing tank having the filtering means by spontaneous fall. A predetermined amount of the solid processing agent is housed in a package that is divided and hermetically sealed so that the air permeability between the solid processing agent and the adjacent solid processing agent is blocked. Therefore, moisture resistance is guaranteed unless the package is opened.

As an embodiment, a configuration is conceivable in which a package composed of at least two packaging materials sandwiching the solid processing agent is closely adhered or adhered to each other so that the periphery of the solid processing agent can be separated. . By pulling each packaging material sandwiching the solid processing agent in different directions, the closely contacted or adhered contact surfaces are separated, and the solid processing agent can be taken out.

As another embodiment, it is conceivable that at least one of the packages made of at least two packaging materials can be opened by an external force so as to sandwich the solid processing agent. The term "opening" as used herein means a cut or break that leaves a part of the packaging material. As the unsealing method, the solid processing agent is forcibly pushed out by applying a compressive force from the packaging body on the non-opening side to the packaging body which can be opened through the solid processing agent, or on the packaging body on the openable side. It is considered that the solid processing agent can be taken out by making a cut with a sharp member.

The supply start signal is obtained by detecting the processing amount. Further, the driving means for separating or unsealing operates based on the obtained supply start signal. The supply stop signal is obtained by detecting the information that the supply of the predetermined amount is completed. Further, based on the obtained supply stop signal, the driving means for separating or unsealing is controlled to stop.

The solid processing agent supplying means has a control means for supplying a fixed amount of the solid processing agent in accordance with information on the processing amount of the light-sensitive material, which is an important requirement in the present invention.
That is, in the automatic processor of the present invention, it is necessary to keep the component concentration of each processing tank constant and to stabilize the photographic performance. What is the throughput information for 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 liquid, 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 the treating agent in the liquid. It may be detected before or after the photosensitive material is carried into the processing liquid, or at any timing during immersion in the processing liquid. It may also be the amount of the light-sensitive material printed by the printer. Furthermore, it may be the concentration of the treatment liquid contained in the treatment tank or the change in the concentration. Further, it may be the amount of the treatment liquid which is discharged to the outside after drying.

The solid processing agent of the present invention may be supplied in a processing tank, but preferably, it is communicated with a processing section for processing a light-sensitive material, and a processing solution flows between the processing section and the processing section. It is preferable that the structure is such that the dissolved components move to the processing section because there is a certain amount of processing liquid circulation between the processing section and the processing section. The solid processing agent is preferably supplied in the temperature-controlled processing liquid.

Generally, since the temperature of an automatic processor is controlled, the temperature of the processing solution is controlled by an electric heater. A heat exchange section is provided in an auxiliary tank connected to the processing tank as a processing section, and a heater is installed to replenish the tank. Is equipped with a pump that feeds the liquid from the processing tank in a constant circulation amount and keeps the temperature constant.

Usually, a filter is arranged for the purpose of removing the crystalline foreign matter that is mixed in the processing liquid or is generated by crystallization, and plays a role of removing the foreign matter.

The most preferable method is to supply the solid processing agent to a place where the temperature is adjusted, such as a place communicating with the processing section such as this auxiliary tank. This is because the insoluble component in the supplied processing agent is blocked from the processing section by the filter section, and the solid content can be prevented from flowing into the processing section and adhering to the photosensitive material.

Further, when the processing agent supply section is provided in the processing tank together with the processing section, it is preferable to devise a shield or the like so that the insoluble portion does not come into direct contact with the film or the like.

As for the material of the filter and the filtering device, any material used in a general automatic developing machine can be used in the present invention, and the special structure or material does not influence the effect of the present invention.

The present invention eliminates the need for a tank or the like for storing the replenisher by supplying the solid processing agent to the processing tank, which makes the automatic developing machine compact and, when it has a circulation means, dissolves the solid processing agent. The property is also very good.

The solid processing agent of the present invention can be used as all known solid measuring means including being measured in advance as a measuring means.

Considering the compactness of the automatic processing machine and the weighing accuracy, it is desirable that the automatic weighing machine be weighed in advance.

After the measurement of the solid processing agent of the present invention is completed, the feeding time in one feeding operation must be within 30 seconds.

When the solid processing agent is directly supplied to the processing tank,
Controlling the supply time is the most important factor in securing the moisture-proof property of the treatment agent and maintaining the supply accuracy, and was a factor unthinkable in the conventional liquid agent replenishment system.

The amount of the processing agent to be supplied at one time of the solid processing agent of the present invention is preferably 0.1 to 50 g, 1 to 20 g for the color developing solution for color, and 5 to 50 g for the fixing solution and the bleach-fixing solution. , 0.1 to 10 g in the stabilizer, 0.5 to 20 g in the black and white developer is particularly preferable, it becomes very difficult to store the measurement accuracy is less than this range, solidified at the supply port is more than this range. Increase. It can be said that the above range is preferable also from the viewpoint of solubility in solid treatment.

【Example】

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

In FIG. 1, in the lower left part of the photographic printing apparatus B, there is set a magazine M containing photographic paper, which is an unexposed silver halide photographic photosensitive material, in a roll form. The photographic printing paper pulled out from the magazine is cut into a predetermined size via the feed roller R and the cutter section C to become a sheet-shaped printing paper. The sheet-shaped printing paper is conveyed by the belt conveying means B, and the image of the original image O is exposed in the exposure section E. The exposed sheet-shaped printing 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 papers are color developing tank 1A, bleach-fixing tank 1B, stabilizing tanks 1C, 1D, 1 which are processing tanks.
It is sequentially conveyed in E (substantially three tanks) by roller conveying means (reference symbol None), and color development processing, bleach-fixing processing, and stabilization processing are performed respectively. The sheet-shaped printing paper that has been subjected to each of the above processes is dried in the drying unit 35 and discharged to the outside of the machine.

Incidentally, the alternate long and short dash line in the figure shows the transport path of the silver halide photographic light-sensitive material. In the embodiment, the light-sensitive material is introduced into the automatic developing machine A in a cut state, but it may be introduced into the automatic developing machine in the form of a strip. In that case, if an accumulator for temporarily retaining the photosensitive material is provided between the automatic developing machine A and the photoprinting machine B, the processing efficiency is improved. Further, it goes without saying that the automatic developing machine according to the present invention may be configured integrally with the photo printing machine B or may be a single automatic developing machine. Further, it goes without saying that the silver halide photographic light-sensitive material processed by the automatic developing machine according to the present invention is not limited to exposed photographic paper, and may be exposed negative film or the like. Further, the description of the present invention will be made on a developing machine of substantially three tanks including a color developing tank, a bleach-fixing tank, and a stabilizing tank, but the present invention is not limited to this, and the color developing tank, the bleaching tank, and the fixing tank can be used. The present invention can be applied to an automatic developing machine having substantially four tanks including 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 I-I cross section of the automatic developing 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 tank are stable. All of the tanks 1C, 1D and 1E will be referred to. It should be noted that, in the figure, a transporting means for transporting the photosensitive material and the like are omitted for easy understanding of the configuration. Further, in this example, the case where the tablet 13 is used as the solid processing agent will be described.

The processing tank 1 is a processing section 2 for processing a photosensitive material.
And a solid processing agent supply section 11 for supplying tablets 13 integrally provided on the outside of the partition wall forming the processing section. The processing section 2 and the solid processing agent supply section 11 are partitioned by a partition wall 12 having a communication window formed therein so that the processing liquid can flow therethrough. Since the supply section 11 is provided with the section 14 for receiving the processing agent, it does not move to the processing section 2 in a solid state.

The cylindrical filter 3 is a solid processing agent supply unit.
It is provided below 11 so as to be replaceable, and has a function of removing insoluble matter such as paper waste in the processing liquid. In the filter 3, a circulation pump 5 (circulation means) is provided through a circulation pipe 4 that penetrates the lower wall of the solid processing agent supply unit 11.
It communicates with the suction side of.

The circulation system is composed of the circulation pipe 4 forming the liquid circulation passage, the circulation pump 5, the processing tank 1 and the like. The other end of the circulation pipe 4 communicating with the discharge side of the circulation pump 5 penetrates the lower wall of the processing unit 2 and communicates with the processing unit 2. With such a configuration, when the circulation pump 5 operates, the treatment liquid is sucked from the solid treatment agent supply unit 11 and discharged to the treatment unit 2 so that the treatment liquid mixes with the treatment liquid in the treatment unit 2 and the solid treatment agent is again supplied. The circulation that enters the supply unit 11 is repeated. The flow rate of this circulating flow is 1
The flow rate is preferably 0.1 (rotation = circulation amount / tank volume) or more with respect to the tank volume per minute, and more preferably 0.5 to 2.0 rotations. Further, the circulation direction of the processing liquid is not limited to the direction shown in FIG. 2 and may be the opposite direction.

The drainage pipe 6 is for overflowing the processing liquid in the processing section 2, and keeps the liquid surface level constant, as well as components brought in by adhering to the photosensitive material from another processing tank, The components leaching from the photosensitive material are stored,
Helps prevent the increase.

The rod-shaped heater 7 is arranged so as to penetrate the upper wall of the solid processing agent supply section 11 and be immersed in the processing solution in the solid processing agent supply section 11. This heater 7 is used in the processing tank 1
It heats the processing liquid inside, in other words, processing tank 1
Temperature range suitable for processing the processing liquid inside (eg 20-55 ℃)
It is a temperature adjusting means that is held at.

The processing amount detecting means 8 is provided at the entrance of the developing machine and is used for detecting the processing amount of the photosensitive material to be processed. The processing amount 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 preset, the processing area of the photosensitive material can be calculated from the width information and the time information. The processing amount detecting means 8 may be any one capable of detecting the width and the conveying time of the photosensitive material such as an infrared sensor, a micro switch and an ultrasonic sensor. Further, in the case of a device capable of indirectly detecting the processed area of the photosensitive material, for example, in the case of a printer processor as shown in FIG. 1, the amount of the photosensitive material that has been printed or the number of processed photosensitive materials having a predetermined area is set. It may be detected. Further, the detection timing is before the treatment in this example, but may be after the treatment or during the immersion in the treatment liquid (in such a case, the position where the treatment amount detecting means 8 is provided is set. This can be done by appropriately changing the position that can be detected after processing or the position that can be detected during processing). Furthermore, as the information to be detected, the processing area of the photosensitive material has been described in the above description, but the present invention is not limited to this, and the processing amount of the photosensitive material to be processed, processed, or being processed is not limited to this. It may be a proportional value, and may be the concentration of the treatment liquid contained in the treatment tank or a change in the concentration. Further, it is not necessary to provide the processing amount detecting means 8 for each of the processing tanks 1A, 1B, 1C, 1D, 1E, and it is preferable to provide one for each automatic developing machine.

The processing agent supply means 17 for supplying the solid processing agent stored in the cartridge 15 as the storage means to the processing tank is
A cartridge (15), which is arranged above the filtering section (section) (14) and encloses tablets (13) that are solid processing agents, and an extruding member (10) configured to extrude one or more tablets (13). The processing agent supply means 17 is a processing agent supply control means 9 described later.
The tablet 13 that has been on standby is extruded by the extruding member 10 in synchronism with the supply signal that is controlled by the processing agent supply control means 9, and the tablet 13 is filtered in the solid processing agent supply section 11 (section). Supply to 14.

Therefore, in this case, since the solid processing agent pre-measured as the tablets 13 is supplied by its own weight, the supply can be said to be substantially instantaneous.

When a plurality of tablets, granules or powders are prepared, the operation time may be controlled so that the supply time is within 30 seconds.

In the present invention, the tablets 13 are supplied to the filtration section (section) 14 in the solid processing agent supply section 11, but the location to be supplied may be anywhere in the processing tank 1,
That is, in the present invention, it suffices if the solid processing agent can be dissolved using the processing liquid, components are appropriately supplied according to the processing amount of the photosensitive material, and the processing characteristics of the processing liquid in the processing tank 1 are kept constant. However, it is more preferable that the solid processing agent is supplied into the circulation path of the processing liquid. In addition, the treatment agent supply means 17 is configured so that moisture in the treatment tank of the automatic processing machine and humidity in the outside air, and scattered treatment liquid do not come into contact with the solid treatment agent before being supplied to the treatment tank. Is preferred.

The filtering means (section) 14 is a solid processing agent supply section.
An insoluble component by the tablet 13 which is dipped in the treatment liquid in 11 and supplied by the treatment agent supplying means 17, for example, an insoluble component mixed in the tablet 13, and a tablet formed by disintegrating the tablet 13.
Removes not only tablets 13 but also solid processing agent-derived lumps, such as 13 lumps, that could damage the resulting image or cause inadequate processing of the adhered areas. Is. The filtering means (section) 14 is made of resin. It is not essential that the filtering means (section) 14 is provided in the solid processing agent supply unit 11, and the tablets 13 supplied by the processing agent supply unit 17 may be the photosensitive material transport path shown in FIG. 1 or the processing section. It is only necessary to supply the treatment liquid in the No. 2 inside.

The processing agent supply control means 9 is a processing agent supply means.
When the processing amount information (processing area in this embodiment) of the photosensitive material detected by the processing amount detection means 8 reaches a predetermined constant value, a processing agent supply signal is sent to the processing agent supply means 17. It is something that is emitted. The treatment agent supply control unit 9 may control the treatment agent supply unit 17 so as to supply the required amount of treatment agent to the solid treatment agent supply unit 11 according to the treatment amount information.

The supply time may be controlled by the processing agent supply means 17 or the signal of the processing agent supply control means 9.

Next, the operation of the present invention will be described with reference to FIG. For the exposed photosensitive material, the amount of processing amount is detected by the processing amount detecting means 8 at the entrance of the automatic developing machine A.
The processing agent supply control unit 9 sends a supply signal to the processing agent supply unit 17 when the cumulative area of the photosensitive material to be processed reaches a predetermined area in accordance with the processing amount information detected by the processing amount detection unit 8. Emit. Processing agent supply means 17 which has received the supply signal
Presses the tablets 13 with the extrusion member 10 and supplies the tablets 13 to the filtering means (section) 14 in the solid processing agent supply section 11. At this time, the supply time is substantially instantaneous. The supplied tablets 13 are dissolved by the processing liquid in the solid processing agent supply section 11, but by the circulation means, the solid processing agent supply section 11 → circulation pump 5 → processing section 2 → communication window → solid processing agent supply section 11 Dissolution is promoted by the circulating processing solution. On the other hand, the detected light-sensitive material is sequentially conveyed by the roller conveying means in the color developing tank 1A, the bleach-fixing tank 1B, and the stabilizing tanks 1C, 1D, 1E (see the automatic processor A in FIG. 1). Incidentally, a color developing tank 1A, a bleach-fixing tank 1B, and stabilizing tanks 1C and 1 which are processing tanks, respectively.
Each of D and 1E may be provided with a treatment agent supply means 17, and may be supplied simultaneously. Further, the timing supplied by each supply means may be different,
Further, the predetermined area for controlling the processing agent supply means by the processing agent supply control means 9 is defined by the processing tanks 1A, 1B,
It is needless to say that 1C, 1D, and 1E may be the same, but may be different from each other.

Not only in this example but also in the example described below,
In the bleach-fixing tank 1B and the stabilizing tanks 1C, 1D, 1E,
Since it has the same structure as the color developing tank 1A, the processing tank 1 will be described below.
In the following description, the color developing tank 1A and the bleach-fixing tank 1
B, stabilization tanks 1C, 1D, and 1E are all referred to here,
In the drawing, the same reference numerals as those in FIG. 2 having the same functions as those in FIG. 2 are omitted, and the description thereof is omitted here. Further, in order to make the configuration easy to understand, a conveying means for conveying the photosensitive material, etc. Is omitted. Although the filtering means is described as a preferable example in the present example, the effects of the present invention can be sufficiently achieved without the filtering means in the present invention.

As described above, according to the present invention, the replenishing tank which has been conventionally required is not required and the space for the replenishing tank is not required, so that the automatic processor can be made compact and the solid processing agent can be used in the processing tank. Since the liquid is supplied, there is no need for liquid preparation work, there is no liquid scattering during liquid preparation, and no adherence or contamination to human bodies, clothes, or peripheral devices, and handling is easy.
Since it is possible to minimize the influence of the atmosphere from the temperature-controlled processing tank, the replenishment accuracy to the processing liquid is increased and the processing components to be replenished are not deteriorated and have stable processing characteristics.
It has an excellent effect.

Next, as another example of the present invention, FIG. 3 is a schematic view of the color developing tank 1A in the II section of the automatic developing machine A of FIG. FIG. 3 is a cross-sectional view of a portion with a processing agent supply means. FIG. 4 shows the automatic processor A of FIG.
FIG. 3 is a schematic front view showing the above from above (however, the route is described for the water replenishing means for explanation). FIG. 5 is a block diagram relating to the control according to this example. FIG. 6 is a block diagram in which a pre-programmed evaporative replenishment water setting means 23 is added to the control means. 3 and 4, a replenishing water tank 43 for storing replenishing water is shown. Further, in this example, a case where tablets are used as the tablets 13 will be described.

First, the parts in FIGS. 3 and 4 different from those in FIG. 2 will be described.

The replenishing water supply means 42 is means for replenishing replenishing water (replenishing water) from the replenishing water tank 43 which stores the replenishing water to the treatment agent supplying section 11, and is a hot water replenishing device 32 including a pump, a temperature controller, and the like. It has a solenoid valve 33 and a rehydration pipe 36. The replenishing water supply means 42 is for compensating the water taken out by the photographic material and the water evaporated from the surface of the tank, while diluting the cumulative suppressing component eluted by the reaction. A replenishment water tank or a replenishment water pump may be provided for each of the treatment tanks 1A, 1B, 1C, 1D, and 1E, but the replenishment water to be replenished is the same replenishment water in any tank. If it is set, the automatic developing machine becomes compact, and more preferably, only one replenishing water tank and replenishing water pump are provided in the automatic developing machine.
An electromagnetic valve is installed in the water supply path (pipe, etc.) so that the required amount can be replenished to each treatment tank when necessary, or the replenishment amount can be adjusted by adjusting the diameter of the replenishment pipe. By doing so, only one replenishing water tank 43 and one replenishing water pump can be provided in the automatic developing machine, and the size is further reduced. Incidentally, for the stabilizing tanks 1C and 1D which are processing tanks, respectively, by supplying the stabilizing solutions overflowing from the stabilizing tanks 1D and 1E, respectively, it becomes possible to omit the replenishing water supply means. Further, it is preferable that the replenishing water in the replenishing water tank is temperature-controlled.

The water to be replenished is not only well water such as well water and tap water, but also antifungal agents such as isothiazoline type and chlorine releasing compounds and some sulfite chelating agents Ammonia and inorganic salts Known compounds and methods can be used as long as they do not affect photographic performance, such as those containing .

This replenishment water control means controls the replenishment water supply means 42 by means of the evaporation replenishment water replenishment setting means 23 which is preprogrammed according to the environmental temperature / humidity (relative humidity) of the installation location and / or the treatment amount detection means 8 It is a control means for controlling the replenishment water supply means 42 according to the processing amount information and the like detected by. The replenishment water supply control means is not limited to responding to the processing amount information detected by the processing amount detecting means 8 and may be controlled according to the information that the processing agent has been supplied by the processing agent supplying means 17. Good.

3 and FIG. 2 are the same as those in FIG. 2 except for the above, the functions and the like are the same.
I will explain it.

The heater 7 is arranged at the bottom of the processing section 2 and heats the processing solution in the processing section 2. In other words, the heating solution in the processing section 2 and the solid processing agent supply section 11 is heated. It has a temperature control function of maintaining a temperature range suitable for processing (for example, 20 to 55 ° C).

A circulation pipe 4 and a circulation pump 5 are provided as circulation means in the same manner as in FIG. 2, but the difference from FIG. 2 is that the direction of circulation of the treatment liquid is opposite, that is, the treatment liquid is treated. Part 2 → Circulation pump 5 → Solid processing agent supply unit 11 →
It circulates from the communication window to the processing unit 2.

The treating agent supplying means 17 supplies the tablets 13 as the solidifying agent enclosed in the cartridge 15 to the filtering section (section) 14 in the solid treating agent supplying section 11 by the pushing claw 18. . 2 differs from that shown in FIG. 2 in that the cam 19 is actuated by the shaft 1 rotation stop mechanism and the pushing claw 18 is actuated, and the tablet 13 that has been on standby is supplied to the processing tank 1, and the next tablet 13 is the tablet pushing spring. Since the spring 21 urges the spring from the upper side to the lower side, it quickly becomes a standby state. At this time, the treatment agent supply means 17 may be a horizontal type or a push-up method from below, and in short, any means capable of supplying the solid treatment agent to the treatment tank 1 within 30 seconds after being metered.

Next, the operation of the present invention will be described with reference to FIGS. 1, 3, 4, and 5. The processed amount of the exposed photosensitive material is detected by the processed amount detecting means 8 at the entrance of the automatic developing machine A. The processing agent supply control means 9 issues a supply signal to the processing agent supply means 17 when the accumulated area of the photosensitive material to be processed reaches a predetermined area in accordance with the processing amount detected by the processing amount detection means 8. . Upon receiving the supply signal, the processing agent supply means 17 extrudes the tablet 13 with the extrusion member 10 to
13 is supplied to the filtration section 14 in the solid processing agent supply section 11 substantially instantaneously. The supplied tablets 13 are dissolved by the processing liquid in the solid processing agent supply unit 11, but are circulated through the processing unit 2 → circulation pump 5 → solid processing agent supply unit 11 → communication window → processing unit 2 by circulation means. Dissolution is promoted by the existing processing solution. On the other hand, the replenishment water supply control means 42, when the accumulated area of the photosensitive material to be processed reaches a predetermined area according to the processing amount information detected by the processing amount detecting means 8,
A rehydration signal is issued to (the hot water supply device 32 and the solenoid valve 33). Upon receiving the replenishment water signal, the replenishment water supply means 42 controls the hot water replenishment device 32 and the solenoid valve 33 to supply the replenishment water stored in the replenishment water tank 43 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 to this and may be different predetermined areas. On the other hand, the detected light-sensitive materials are the color developing tank 1A, the bleach-fixing tank 1B, the stabilizing tank 1C, and the stabilizing tank 1C, which are processing tanks, respectively.
The insides of 1D and 1E are sequentially conveyed by the roller conveying means.

Although the automatic developing machine including various processing tanks has been described above, the processing tanks include a developing tank for containing a developing solution, a bleaching tank for containing a fixing solution, and a bleach-fixing solution. A bleach-fixing tank, a fixing tank for containing a fixing solution, and a stabilizing tank for containing a stabilizing solution, and at least the accommodating means and / or fixing means, the supplying means, and the control means are respectively described above. An automatic developing machine for a color negative film provided for each processing tank and a developing tank for containing a developing solution as a processing tank, and a fixing tank for containing a fixing solution, and at least the storage means and / or The effect of the present invention was also confirmed in the automatic developing machine for black-and-white silver halide photographic light-sensitive material, in which the fixing means, the supplying means and the control means are provided for each of the processing tanks.

Example 2 Konica QA Paper Type A

32 (a) and 32 (b) show a two-division cutting method for the continuous package 603.

When the photosensitive material is processed, the processing amount detecting means 8
When a certain amount is reached, a signal is sent by the processing agent supply means and the conveying roller 502 rotates, and at the same time, the round blade 301 made of ceramic or stainless steel rotates and the lower part of the continuous package 603 is divided into two. Cut extrusion member 10
To supply. The repackaging body 603 divided into two is spread by suction on the suction guide 202 on both sides, and the extruding member 10 inside is easily dropped. The empty package 603 without the solid processing agent 10 is moved by the transport roller 401 at the time of the next supply of the extrusion member 10 and is discarded in the package storage box 101.

In addition to the above-mentioned method, this two-division may be made by attaching a notch or the like to the continuous package and tearing it while winding it with a roller.

In the case of such a system, the extrusion member 10 is a powder agent,
Granules or tablets may be used, but tablets that do not adhere to the punch male mold are preferable. Further, the tablet does not adhere to the seal of the package so much that the stain is less likely to occur.

The used package 603 can be disposed of in the package storage box 101 and can be discarded together.

In this case, the starting point of the feeding operation in the present invention is the point at which the packaging material packaged by the four-sided seal is divided and cut.

In one feeding operation, the feeding time for feeding the solid processing agent pre-measured by the packaging is the feeding roller 50.
By adjusting the rotation speed of No. 2, the two-division cut time was changed so as to be as shown in Table 1.

I observed.

The evaluation was performed as follows.

Evaluation Situation of formation of solidified matter ◎ Almost never generated ○ Small amount generated △ Large amount generated × Large amount generated, affecting solid supply agent supply operation × × Large amount generated, solid processing agent supply failed Possible results are shown in Table 2.

[0184]

[Table 2]

However, the color developing agent in the color developing agent is
Replenishment rate of 50 ml / m ² is 1.2 times, 25 ml / m ² is 1.45 times, 100 ml
At / m ² , it was changed to 0.9 times and the amount of consumption was corrected.

The amount of maleic acid in the bleach-fix solution is
At the time of lowering the replenishment rate, the amount was increased by the amount corresponding to the increase in pH due to the mixing of the color developing solution. Table 2 shows a comparative example of each method.

As is clear from Table 2, when the supply time of the present invention is set within 30 seconds, preferably within 15 seconds, and most preferably within 3 seconds, solidified substances are hardly generated near the supply port of the supply device.

Further, since the effect of the present invention becomes more remarkable when the replenishing water, that is, the replenishing amount is low, it can be said to be one of the preferable embodiments of the present invention.

(Example 3) In Example 2, the solid processing agent in the color developing section was changed in the combination of the supplying device and the solid processing agent for color developing as follows.

Combination (1) Solid processing agent supply device ... Supplying device for powdery processing agent shown in FIG. 9 In the supplying device 70, the powdery processing agent is put in the hopper 71 and the piston 75 is horizontal according to the processing amount of the photosensitive material. Direction (to the right), a fixed amount of powdered material enters the measuring hole 72, and the piston 75 moves in the horizontal opposite direction (to the left), and the discharge unit 74 supplies the fixed amount of powdered material to a constant temperature tank (filter tank). .

The feeding time after the measurement in the measuring hole 72 was set to the time shown in Table 3 by changing the moving speed of the piston.

Solid developing agent for color development: powdery treating agent The powdery treating agent is the same as that in the operations (A) to (D) of Example 2 except for the granulating step and the tableting step (A) to (D). It is obtained by uniformly mixing the powdery treatment agent obtained in step 1).

Combination (2) Solid processing agent supply device ... Powder processing agent supply device shown in FIG. 9 Solid developing agent for color development ... Granular processing agent The granular processing agent is the same as in Example 2 ( In (A) to (D), obtained by (A) to (D) except for the tableting process.

It is obtained by uniformly mixing the granular treatment agents.

Combination (3) Solid processing agent supply apparatus ... Tablet type processing agent supply apparatus shown in FIG. 13 FIG. 13 is a packaged tablet according to the present invention (predivided weighing)
1 is a diagram showing an example of a parts feeder system supply device 120 for a machine.

The packaged tablet chemical packaging material (A) or (B) was opened and put in the hopper 133. At that time, fine powder was not generated, and there was no caking, and the handling was good. The movable member 124 is rotated by the signal of the remaining amount detecting means 125, and the tablet caking is aligned with the tablet aligning unit 129. The movable member 124 stops after a certain amount of alignment. At this time, sweeper 1
23 is very effective for the tablets to enter the pocket 122 of the movable part 124 and be aligned with the alignment part 125.

Processing agent supply means according to the processing amount of the photosensitive material
126 works and the first shutter 131 rotates and the tablet chemical drops down. Next, the first shutter 131 rotates in the reverse direction and one tablet is sandwiched between the shutters 131 and 132. Shutter 132
Rotates and the tablet chemical passes through the discharge part 128 and is supplied to the supply part. Next, the shutter 132 reversely rotates and the shutter 131 closes.

The supply time of the tablets, which were measured in advance, was set to the time shown in Table 3 by adjusting the movable member 124 and the rotation speed.

Each treatment is 5 m ^{2 of} color paper per day.
Then, the overflow was carried out until the overflow amount became 5 times as much as the tank liquid, and as in Example 2, the generation state of the solidified substance in the vicinity of the processing agent supply section of the color developing tank was observed.

For comparison, the solid processing agent of combination 3 was dissolved in a replenishing tank as in the conventional type and replenished with a conventional bellows pump as a replenishing solution, and in this case, coloring of potassium carbonate at the end of running was completed. The residual amount of potassium carbonate in each treatment pattern was determined by setting the concentration in the developer tank to 100%.

Table 3 shows the above results.

[0202]

[Table 3]

As is clear from Table 3, when the solid processing agent is in the form of granules or tablets, the state of solidified product generation, which is the effect of the present invention, becomes good, and the components become stable during running. It can be seen that the replenishment accuracy is also good.

Example 4 Combination of Example 3 (2)
In Table 3, the amount of the solid processing agent supplied at one time was changed as shown in Table 4, and the same evaluation as in Example 3 was performed.

The results are shown in Table 4.

[0206]

[Table 4]

As is clear from Table 4, in the present invention, when the amount of the solid processing agent supplied at one time is too large, the solidified product is deteriorated and the replenishment accuracy is deteriorated. When the amount is too small, the solidified product is generated well, but the replenishment accuracy is deteriorated. Therefore, it can be seen that the effect of the present invention becomes more remarkable when the solid processing agent supplied at one time is in the range of 0.1 to 50 g, preferably 0.8 to 20 g.

(Embodiment 5) Another embodiment of the solid processing agent supply device of the present invention will be described below.

FIG. 7 (A) is a sectional view of the powdery processing agent supply device, and FIG. 11 (B) is a perspective view of the package. The supply device 50 includes a hopper or package 51 for storing the powdery treatment agent, a measuring hole 53 for measuring the powdery treatment agent, and a rotary drum 52 for supplying a fixed amount. In the case of a hopper, it is desirable to have a dehumidifying function such as injecting dehumidifying air into the hopper. The rotary drum 52 has a moisture-proof function by shifting the positions of the measuring hole 53 and the discharging portion 56. package
The 51 seal was cut and loaded on top of the feeder. A certain amount of powdered chemical is measured in the measuring hole 53, and when the drum 52 is rotated by the command of the processing amount detecting means of the photosensitive material and is in communication with the discharge part 56, it stops and passes through the discharge part 56, and a fixed amount of powdery chemicals. Is supplied to the constant temperature section (filter tank) of the automatic processor. After the supply is completed, when the drum 52 rotates and the measuring hole 53 and the supply unit 57 communicate with each other, the drum 52 is stopped and the measurement of the powdery chemical is started.

In this case, the supply time of the present invention needs to be set within 30 seconds by changing the rotation speed or the rotation speed of the drum 52.

FIG. 8 is a perspective view of another supply device for the powdery treatment agent.

The supply device 60 is divided into a plurality of powdery chemical storage parts 63, and is devised so as to be stored separately for each part as in the conventional concentration kit. Further, there is a dehumidifying device 65 for improving the preservability of the powdery chemical in the storage portion.

According to the processing information of the photosensitive material, the rotating body 67 quantitatively transfers the powdery processing agent received on the table 66 to the discharging section 68 for each component and supplies it.

In this case, the supply time of the present invention needs to be set within 30 seconds by changing the rotation speed or the rotation speed of the rotating body 67.

FIG. 10 is a cross-sectional view showing still another supply device for the powdery treatment agent.

The supply device 80 has a function of entering (loading) the package 81 into the powdery treatment agent 88 and automatically opening it by the roller 83, and controlling the rotation speed of the screw 82 to discharge the powdery chemicals. It is a device supplied by 84.

Since it has a function of automatically opening the package, fine powder does not fly at the time of opening and mounting, which is good. In this method, measurement is performed by the size of the pitch (peak / valley) of the screw.

In this case, the feeding time of the present invention is the screw
It is necessary to set within 30 seconds by changing the rotation speed of 82.

Sectional drawing which shows the loading state of the solid processing agent packed by PTP.

The solid processing agent packaged in PTP is stored in the processing agent storage container, and may be stored individually in the storage container, or may be a cartridge type in which the solid processing agent is stored in advance. Known materials can be used for PTP packaging, and the solid processing agent is preferably packaged in the form of tablets.

The solid processing agent packaged in PTP is supplied from below the storage container, and when a certain amount of the photosensitive material is processed, the information of the processing amount detection means is sent to the processing agent supply control means and the solid processing agent packaged in PTP by the motor. The lower part of the PTP package (mainly made of aluminum) is peeled off by pushing the processing agent onto a wedge-shaped fixing plate and crushing it, and the solid processing agent is supplied to the processing tank from the supply port. The empty PTP package after supply is further pushed out and discarded from the waste port. As a crushing means, there is a method of using a roller other than using a wedge, and the method can be arbitrarily selected.

In this case, the supply time of the present invention needs to be set within 30 seconds by changing the extrusion speed or the number of extrusions.

Further, it is desirable that the hopper has a dehumidifying function by dehumidifying air or the like. The signal of the remaining amount detecting means 109 causes the stirrer 106 to rotate, and the tablets 105 are aligned in the tablet alignment unit 110. The processing agent supply control means 103 operates according to the processing amount of the photosensitive material, and the rotary table 107 conveys the tablet and supplies it from the discharge section 108 to the supply section. The rotary table 107 rotates once and stops at the instruction of the rotary table control means (tablets can be supplied several times with one instruction). The tablets enter the holes in the turntable 107.

In this case, the supply time of the present invention needs to be set within 30 seconds by changing the rotation speed or the rotation speed of the rotary table 107.
