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 having a processing agent replenishing means and a method for processing light-sensitive materials. The present invention relates to an automatic developing machine for silver halide photographic light-sensitive materials and a light-sensitive material processing method, which is provided with a means for reducing the amount of waste liquid and waste water generated by supplying a replenishing processing agent.

[0002]

2. Description of the Related Art Among silver halide photographic light-sensitive materials (hereinafter referred to as light-sensitive materials), as a light-sensitive material generally processed by an automatic developing machine having a processing agent replenishing device, negative paper for color print, There are color reversal papers, color negative films, color reversal films, medical films such as X-ray films and screen films, printing films such as gravure films and copying films.

In the above automatic developing machine, a replenishing processing agent is supplied in order to maintain the processing performance in accordance with the processing amount of the photosensitive material. More specifically, replenishment corresponding to the area and length of the light-sensitive material to be processed and replenishment in consideration of the blackening rate are usually performed. Further, when the processing amount of the photosensitive material by the automatic processor is small, the influence of the deterioration of the processing solution with time becomes a problem, so that the replenishing amount per area of the photosensitive material is increased, or the replenishment with time is performed, Replenishment such as water replenishment for the purpose of supplementing evaporation is being performed.

The reduction of the replenishing amount of the replenishing agent corresponding to the processing amount of the light-sensitive material has been studied in the past for the purpose of cost reduction, reduction of replenishing agent addition work, and reduction of waste liquid amount. In the market, various systems and methods are provided. For the purpose of reducing the amount of waste liquid, the amount of waste liquid is also reduced by a waste liquid treatment device.

In the photographic developing method and apparatus disclosed in Japanese Patent Laid-Open No. 62-9351, the space inside the developing tank is filled with deoxidized air in contact with the waste developing solution. Further, the photosensitive material processing apparatus disclosed in JP-A-4-241350 is provided with a drying section, a heat radiating section and a heat absorbing section of a heat pump in a dry air circulating system, and the dry heat is absorbed by the heat radiating section and the heat absorbing section. It is for heating and dehumidifying.

Further, a method and apparatus for reducing the replenishment amount by regenerating the processing liquid have been proposed and provided. However, a certain amount of the replenishing treatment agent is used, and a large amount of waste liquid is generated by the treatment, and there is a strong demand for low replenishment treatment and reduction of the waste liquid amount.

[0007]

The causes of fatigue of the developing solution include changes over time and changes in processing, and it is necessary to replenish a new developing solution in accordance with these changes. The processing change is caused by developing the light-sensitive material, and since this processing change is almost proportional to the area of the light-sensitive material to be processed, a new developer may be replenished depending on the processing amount of the light-sensitive material. Good. The change with time is a change caused by air in contact with the developing solution, and is oxidation of the developing solution by oxygen in the air and a decrease in pH of the developing solution.
Since this change with time greatly changes depending on the developing conditions and environment, it is difficult to determine the replenishment amount of the developing solution corresponding to this change with time. Conventionally, when an appropriate period of use has elapsed, the test photosensitive material (control strips) exposed using a density wedge is developed, and the finished density is examined to check the degree of fatigue of the developer, It decides when to correct the amount of replenishment of the solution and when to replace the entire developer. However, since this management work requires specialized knowledge and skill, it is practically difficult to apply it to minilabs which are becoming widespread at present.

Further, in order to carry out the developing treatment rapidly, it is necessary to raise the pH of the developing solution and to use it at a high temperature. Under such active developing conditions, the above-mentioned change with time is large, and therefore a large amount of developer replenishment is required,
Therefore, the amount of waste liquid also increases.

The operation of the present invention will be described below for each claim.

It is an object of the present invention to reduce the amount of developing replenisher and the amount of waste developing solution in the developing step. The developing solution and the developing replenishing solution used in the developing process of the automatic developing machine mean a developing solution for processing a black-and-white photosensitive material and a color developing solution for processing a color photosensitive material.

Usually, the developer has a buffer containing carbonate, phosphate, etc., and is used in a pH range of about 9.5 to 12.0. In order to stabilize or maintain the pH value, the pH value of the replenisher is set higher than that of the developer in the developer tank (hereinafter referred to as the tank solution), and the replenisher is supplied according to the processing amount. The pH value is maintained. However, if the amount of replenishment is reduced, the pH value of the tank liquid will decrease due to absorption of carbon dioxide gas in the air for a user with a small amount of treatment per day. On the other hand, for users with a large amount of processing, p
H is maintained. In order to prevent such a phenomenon, pH
A means for automatically detecting the value is provided, and it is possible to stably maintain the pH value of the developing tank solution. That is, when the low-cost pH value detecting means is used, the absolute pH value cannot be obtained without correcting the pH detector each time. However, the comparative pH value for a certain standard solution can be measured by alternately measuring the standard solution and the developing tank solution. Then, they have found that by controlling the developing pH with a comparative pH value, the developer pH value can be stably maintained and the pH fluctuation due to low replenishment can be prevented.

It is an object of the present invention to reduce the amount of developing replenisher and the amount of waste developing solution in the developing step.

It has the same object and characteristics as in claim 1, and the amount of the reference liquid used for pH detection may be reduced by moving the pH detection unit.

However, claim 1 has an advantage that the structure is simpler than that of claim 2 (no means for moving the pH detecting part is required).

Action of Claim 3 The object is to stabilize the pH value of the developing solution and the processing performance.

By dividing the developer replenisher into two or more types,
Separates the buffer component and other developing agents that are effective in preventing the pH value from decreasing over time, and when the pH value decreases,
Only the components such as the buffer component and the preservative can be supplied, and the stabilization can be further improved. The concentration of the developing agent also changes with one agent.

It is preferable to separately prepare the working pH reference liquid from the viewpoint of pH value stability, but if the treating agent is a feed treating agent, the discharged liquid can be used as the feeding liquid, so that a special liquid is used. Is preferable because it is not necessary to provide one series. Further, it is preferable that the supply treating agent is a replenishing liquid because the liquid can be quickly renewed.

Effect on Claim 5 Since the effect of bringing in the pH standard solution adhering to the pH detecting portion into the developing solution can be ignored, the processing performance is stabilized,
The structure of the pH detector can be simplified.

It is an object of the present invention to reduce the amount of developing replenisher and the amount of waste developing solution in the developing step.

In the first aspect, the supply amount of the development replenisher is changed, but in the present aspect, the pH adjusting agent is exclusively prepared to further improve the pH.
Achieve stable values and maintain processing performance.

It is an object of the present invention to reduce the amount of developing replenisher and the amount of waste developing solution in the developing step.

A pH adjusting agent is prepared exclusively and p
The H detection electrode is moved.

Action relating to claim 8 The same effect as that of the fourth aspect can be obtained.

Action relating to claim 9 Achieve high accuracy in pH comparison detection and free of waste liquid.

It is possible to reduce the amount of developing replenisher and the amount of developing waste liquid in the developing step.

A technique for stabilizing the pH value of a developer.

That is, the development processing section is covered with a cover or the like to have a sealed structure to some extent, and the carbon dioxide gas in the air is melted by sending the decarbonated gas-treated air into the sealed space by contacting the alkaline agent. It is intended to prevent the pH of the developing tank solution from lowering due to.

Since a sensitive material enters and exits, it is difficult to form a completely closed structure, but it is possible to prevent fresh air containing carbon dioxide gas from entering from the outside by covering with a sealing cover or the like and feeding decarbonated air.

[0062] As the alkali agent for carbon dioxide removal, developer replenisher, to use a development waste, that have a benefit that necessary to prepare an alkaline agent to a dedicated disappears.

It is possible to provide a more preferable device having a simple carbon dioxide gas removal performance and a simple structure. In addition, it is preferable to use a porous body having continuous pores such as a ball filter as the structure of the blown-in portion, and it is preferable to form fine bubbles. Further, as the decarbonation blowing structure, a material having a large continuous pores, for example a honeycomb structure and small particle fillers such as impregnated alkali agent, but it may also be a system for passing air therebetween.

[0064]

By transferring the photosensitive material to the outside of the liquid inside the processing tank and supplying the developing solution with a pump to circulate the developing solution, the amount of the developing solution is 1/100 of that of the conventional liquid immersion transfer method. 1
It is possible to develop with a reduced capacity in the range of 0 to 1/100. Further, by making the development processing system have a closed structure, invasion of carbon dioxide gas is prevented, and a decrease in pH value is also prevented.
Further, since the stored amount is small, the developing tank solution in the tank can be renewed in a short time even with a small replenishing amount, and stable developing performance (finishing of the photosensitive material) can be maintained.

[0066] The developer tank, if provided by connecting the developing solution supply pump for the circulation pump and the silver halide photographic light-sensitive material for temperature control respectively, not being transported to a silver halide photographic light-sensitive material, Basically, the developer supply pump is not operated. However, the temperature control circulation pump is operated to circulate the developer in the tank to keep the temperature of the developer constant. Thereby, to prevent the concentration of the developing solution due to evaporation, to maintain the developing property stably
It is possible .

This is a structure for improving the hermeticity of the developer tank so that the photosensitive material is not damaged at the entrance and exit. That is, it is possible to prevent the processing liquid from drying and depositing on the entrance and exit rollers and damaging the photosensitive material by supplying water to the rollers.
It

[0068] Further, by maintaining the sealing of the unit space during operation stop, the developer deposition by drying such as a roller for the photosensitive material conveying processing unit is prevented.

Next, the silver halide photographic light-sensitive material of the present invention
Of processes other than the development process of the automatic developing machine for
It The amount of replenishment for fixing and bleach-fixing is intended to reduce the amount of waste liquid. A fixing solution in which silver halide is dissolved in high concentration,
The bleach-fix solution is heat-treated so that it can be desilvered, and the silver ion complex is prevented from precipitating in the fix solution and the bleach-fix solution. The silver ion complex is precipitated at low temperature by taking out and cooling. The precipitated solid matter is removed, and the solid solution is returned to the original processing liquid tank. As a result, the replenisher can stably provide fixing performance and bleach-fixing performance by supplying a replenisher and a replenishing amount only for the amount of the component (adhesive or discharged together with the deposit (solid substance) and the component lost by this). Can be maintained.

Conventionally, there is a method of correcting the components after recovering only electrolytic silver, but there are various drawbacks such as decomposition of the preservative components, and it has not been possible to sufficiently reduce the replenishment.
With this method, there is no effect on the components and it is possible to significantly reduce replenishment.

The purpose is to reduce the replenishment amount and the amount of waste liquid for fixing and bleach-fixing.

[0072] In contrast to the in-line silver complex removal scheme,
Out as overflow from for replenishment, a method used as a replenisher which was component correction and silver complexes removed.

By using the heat absorbing portion of the heat pump as the cooling heat source, the heat pump heat source is effectively used. Further, the effects of heat absorption and cooling can be obtained respectively.

It is a condition that the cooling precipitation separation of the silver complex is good, and as a result, low replenishment is good. When the temperature is 30 ° C. or lower, the precipitation separation property is poor. When the temperature is 100 ° C. or higher, the heat energy required for heating and cooling is large, and the cost of the device and the electricity cost are high, which is not preferable. The optimum use range is 30 to 100 ° C.

By using the indirect heat pump as the cooling means, it is possible to effectively use the energy required for cooling, and it is possible to suppress the electricity cost of the automatic processor.

Replenishment amount and waste liquid amount for fixing or bleach-fixing are further reduced. By evaporating and concentrating the fixing and bleach-fixing solution, the amount that must be discharged as an overflow solution is reduced, and the replenishment amount can be reduced.

[0077] Further, efficiently, it is possible to promote evaporation at a low cost, the automatic developing machine surrounding environment and is not be moisture up generating steam.

The amount of waste water of washing water or stabilizing solution is reduced or reduced to zero, and the replenishing amount of the fixing solution or the bleach-fixing solution and the amount of waste solution are not increased. To reduce or eliminate wastewater of wash water and stabilizing solution,
It is known to use washing water and a stabilizing solution in the fixing or bleach-fixing in the previous step and use them as dilution water or dissolving water for a fixing or bleach-fixing replenisher.

However, usually, the replenishment amount of the washing water and the stabilizing solution is
Since it is more than the replenishment amount of the fixer or the bleach-fixer, wash water,
When the overflow of the stabilizing solution is used as the diluting water or the dissolving water of the fixing solution or the bleach-fixing solution, it tends to remain.
If the amount of replenishment for fixing and bleach-fixing is reduced, there will be more surplus.

In the present invention, even if the replenishment amount for fixing and bleach-fixing is reduced, when the washing water or the overflow of the stabilizing solution is used as the diluting water, the fixing or bleach-fixing is not normally performed by diluting too much. Although it becomes diluted, fixing, bleaching fixing,
The washing and washing are stable, and the concentration of fixing and bleach-fixing is maintained by concentrating by greatly promoting the evaporation of the solution. To promote evaporation,
The liquid temperature is preferably in the range of 45 to 90 ° C.

As a decrease in humidity for promoting evaporation, water is recovered as condensed water by cooling the air. As another method, there is a method in which high-humidity air is discharged to the outside of the developing machine by a fan, but this is not preferable because it raises the humidity of the surrounding environment. Then, the condensed water collected here is used for supplementing the washing water or the stabilizing solution. Although the condensed water may contain odorous components and the like, it does not contain metal salts or the like at all, so that stable treatment can be performed without causing precipitation, microorganisms, etc. in the water washing or stabilizing tank.

The heat pump heat source can be effectively used and each effect can be obtained.

The amount of waste liquid for fixing or bleach-fixing and washing or stabilizing can be greatly reduced. In particular, the components that have been washed or stably taken out from the fixing or bleach-fixing to the light-sensitive material and returned to the fixing or bleach-fixing tank again are returned to the fixing or bleach-fixing tank. Therefore, the replenishing components in fixing or bleach-fixing are only the components lost in the cooling precipitation regeneration. Well
In addition , it is necessary to supplement with a replenisher a component that adheres to the light-sensitive material and is washed out with water or stably carried out. Furthermore, significantly reduces the complement Takashiryou and waste amount in synergy. In particular, the amount of waste liquid is significantly reduced by reusing the condensed water, and the condensed water is preferable because it can be used as dilution water for fixing or bleach-fixing.

The main steps of development (color development), fixing or bleach-fixing, washing with water or stabilizing and processing can achieve low replenishment and low waste liquid amount. The low replenishment volume and low waste liquid volume technologies can be combined without any problems, and the total replenishment volume to the developing machine can be reduced.

The purpose of the present invention is to reduce the replenishment of the wash water to be supplied and the stabilizing solution water. The heat pump collects water from the air and uses it for washing and stabilization, thereby reducing or eliminating the time and effort required for the user to carry the water to the water tank. Also,
Normally, tap water is used for washing and stabilizing water, and the water quality is various, and there are problems due to special water quality. However, there is no regional difference in condensed water, and stable treatment is possible.

By cooling the air in the processing unit of the automatic processing machine, an exhaust fan for preventing water droplets from adhering to the top plate or the like provided in the processing unit becomes unnecessary. Further, the exhaust air from the processing section and the drying section has a high humidity, and a large amount of condensed water can be obtained for a certain constant capacity of the heat pump. Alternatively, when trying to obtain a fixed amount of condensed water, it is possible with a small heat pump unit.

By using condensed water for the water for the treating agent used in the automatic processing machine, the user does not need to carry the water at all. Also, troubles due to the difference in water quality of water supply will be eliminated.

The effective use of the heat dissipation part of the heat pump,
Since the electric energy utilization efficiency is about three times that of the electric heater, the total electricity cost can be reduced.

When the amount of condensed water produced is increased to make the supply from tap water zero, it is necessary to provide an apparatus capable of obtaining sufficient condensed water even in winter when the humidity is low. But,
In the rainy season, too much condensed water is generated and left over. This is evaporated by heating to avoid the excess. That is,
There is a problem in stopping the removal of water from the treatment section or the like even if the condensed water tank is full, and it is necessary to always remove the water. The present invention incorporates the treatment of excess water in the automatic processing machine.

As a fixing agent component of the fixing or bleach-fixing solution ,
Contains sulphite and contains sulfite as a preservative component
It is preferable to use a fixing or bleach-fixing solution, that is, a fixing or bleaching-fixing solution in which silver halide or developed silver is dissolved as a silver thiosulfate complex has a silver thiosulfate complex precipitated at a low temperature and a high temperature at a high temperature. It dissolves, has a high fixing and bleach-fixing processing performance and is effective in the method for processing a light-sensitive material of the present invention.

[0091] also found that the cooling precipitation separation of silver thiosulfate complex becomes better.

Next, the processing liquid used in the automatic developing machine for silver halide photographic light-sensitive materials of the present invention will be described.

It is an alkaline developer having a range of 2.0).

In order to maintain the alkalinity of the developer,
It is necessary to use a buffering agent, and examples of the buffering agent include sodium carbonate, potassium carbonate, sodium bicarbonate, potassium bicarbonate, trisodium phosphate, tripotassium phosphate, disodium phosphate, dipotassium phosphate, boric acid. Sodium, potassium borate, sodium tetraborate (boric acid),

2-hydroxybenzoic acid potassium (potassium 5-sulfosalicylate) etc. can be mentioned.

The developing solution requires a black-and-white developing agent, a color-developing agent and a preservative, and a development accelerator,
