Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an automatic processor for processing color photographic materials. More specifically, the present invention relates to an automatic processor for photosensitive materials, which is comprised essentially of color development, bleach-fixing, and stabilization processing steps, and does not substantially have a washing tank.

[Prior Art] Conventionally, processing of color photographic materials has been carried out using automatic processors in processing facilities generally called laboratories, but in recent years there has been a trend toward processing from large-scale laboratories to small-sized laboratories. As is well known, the automatic developing machine used for this purpose automatically carries out processes such as color development, bleaching, fixing, washing and stabilization, and several types of apparatus are known.

In the processing of color photographic materials, the finished photographic performance is important, but the durability of color photographic pigments is also important, and to maintain this, it is important to carry out sufficient washing with water during photographic processing. It has become common knowledge.

[Problems to be solved by the invention] - In the laboratory described above, in addition to submerged water, it is necessary to supply and drain a large amount of water, including cooling water for processing liquid, etc., especially in the case of a large laboratory. In addition to the limited location requirements, the costs required for equipment and human water supply are also large. In so-called mini-labs, where the throughput is small, automatic processors have become smaller and easier to install, and automatic processors have emerged that can easily manage processing so that the processing solution does not become thick even with a small throughput. is strongly desired.

''Based on the current situation, the inventors of the present application firstly made it possible to perform the developing process using an automatic processor without using submersion in water, and secondly, they removed piping that was dangerous to the working environment. ,
Thirdly, it eliminates the need for piping work and makes new installation or relocation extremely easy.Fourthly, it eliminates the need for flushing water and reduces waste liquid, making it easy to chemically and physically treat waste liquid. Furthermore, it should be possible to recover the tombs so that there is less contamination of the tombs.Fifth, it should be possible to omit tap water for cooling if necessary, contributing to water conservation, which is a social need. 6. As a result of our efforts to develop technology to achieve a high update rate of the processing solution even with a low replenishment amount and to reduce deterioration of the processing solution over time, we have already published Japanese Patent Application Laid-Open Nos. 58-14834 and 58-10514. .5 issue,

The treatment time is preferably 0 minutes, most preferably 20 seconds to 3 minutes, and in the case of multiple tank stabilization treatment, it is preferable that the first stage tank be treated for a short time and the second stage tank be treated for a long time.

#It is desirable to sequentially treat the temples with 20% to 50% longer treatment time than the previous tank. Further, it is preferable to perform the stabilization treatment process using a multi-stage tank, and use a backflow system in which the replenisher is replenished from the final stage tank and sequentially overflows to the previous membrane type, since this can reduce the need for replenishment. After the stabilization treatment according to the present invention, no water washing treatment is required at all, but rinsing with a small amount of water in a very short time, surface cleaning, etc. can be optionally performed as necessary.

In particular, it is preferable to wash the transport carriers such as endless belts and sorters for transporting photographic materials by rinsing them with a small amount of water (preferably standing water) or by wetting them with water using a sponge or the like.

When stabilization treatment is performed directly following the bleach-fixing treatment step of the present invention without substantially going through a water washing step, a short period of silver recovery or a Rinsing with water or the like may be provided.

Indicates that it is placed in a bag made of fiber or the like and brought into contact with a stabilizing liquid. Further, after the overflow liquid of the stabilizing liquid of the present invention is brought into contact with the ion exchange resin, at least a part thereof can be used as the stabilizing liquid. This means that the stabilizing liquid is drawn out from the stabilizing tank, is brought into contact with the ion exchange resin by a column method or a mixing method, and then at least a part of it is put into the stabilizing tank. Show that. In this case, "putting into the stabilizing tank" means that the liquid can be put as a replenisher, but preferably it means returning the liquid to the stabilizing tank after ion exchange treatment in a circulation system, regardless of the replenishing system.

The ion exchange resin may be brought into contact with the stabilizing bath in any tank when the stabilizing bath is multi-tank, but it is preferably treated in the tank immediately after the bleach-fixing process. More preferably, this treatment is carried out in two or more tanks, particularly preferably in all tanks.

When there is only one stabilizing bath, the preferred method is to put the ion exchange resin in a resin column and directly connect it to the stabilizing bath. A preferred embodiment when there are two stabilizing baths is as follows:
An ion exchange resin is placed in a resin column or a filter case, and the resin is directly connected to and brought into contact with the 14th fj immediately after the bleach-fixing treatment, and more preferably brought into contact in the same manner in the second tank. When there are three or more stabilizing baths, a preferred embodiment is to directly connect and contact them in the same way as described above in the first tank immediately after the bleach-fixing process, and more preferably in each stabilizing bath other than the first tank. It is a direct connection and contact. As mentioned above, it is most preferable to directly connect the stabilizing tank and bring the ion exchange resin into contact with the stabilizing solution, but if there is no space for installing the resin column and filter case in the automatic processor, overflow or increasing the amount of replenishment may be necessary. Then, the stabilizing solution forcibly taken out from the stabilization tank was brought into contact with the ion exchange resin and stabilized.

The stabilized solution taken out is brought into contact with an ion exchange resin using a resin column, and the stabilized solution after contact is returned to the stabilization tank. In this case, it is preferable to add the stabilizing liquid component after contact. When there are two or more stabilizing baths, the overflow and resin column are used to contact the ion exchange resin from the first bath near the bleach-fixing process, and the mixture is returned to the drier stabilizing bath. In this case, it is desirable to add back the stabilizing liquid components.

Furthermore, although it is possible to reuse the stabilizing solution after contact with the above-mentioned ion exchange resin as a replenisher, in this case it is desirable to add a stabilizing solution component.

In addition, it is preferable that the above-mentioned ion exchange resin be brought into contact with a stabilizing solution, then brought into contact with a bleach-fix solution, and then regenerated. Especially in the case of an anion exchange resin, silver recovery can also be performed by regenerating the resin, which is effective. big.

The case where the stabilizing solution is brought into contact with the ion exchange resin has been described above, but this is not limited to electrodialysis treatment (see Japanese Patent Application No. 59-96352) and reverse osmosis treatment (Japanese Patent Application No. 59-96352).

It is desirable to provide small lids depending on the location of the parts, or to provide individual lids. Although this lid is not shown,
It can be configured to be pulled up to open, pushed down to open, or slid.

B2: Stirring means In order to homogenize the chemical composition, temperature, etc. of the treatment liquid, a stirring means is provided in the replenishment tank.
In the configuration of the stirred forest described in the specification of No. 2, a step or a spacing is arranged inside the replenishment tank to regulate the amount of movement. In addition, as the stirring means, in addition to the agitation system, manual screw, etc. described in the above specification, electric rotary blades such as those found in washing machines, etc., or circulation in the processing liquid circulation system may be used. The configuration is such that a part of the pipe is equipped with a wing. Furthermore, when using a circulation system in this way, it is also effective to allow the treatment liquid to be blown from above in a Java-like manner. In addition, when using a circulation system, a dedicated circulation pump may be installed, but if the configuration is such that the circulation pump of the treatment tank can be used by using a two-way cock, the number of pumps can be reduced. ,
It is advantageous because it can reduce cost and nupaine. Such a structure is particularly effective in the case of a color developing solution containing a light-emitting alcohol, which is difficult to mix and requires strong stirring.

B3: Preparation of processing solution The processing solution used in automatic development processing includes a replenisher solution and a start solution, and the preparation method and apparatus for each are disclosed in Japanese Patent Application No. 59-69158.59-81692.59. -6
9160.59-6916ψ I, 59-
58351.59-58350. This is aimed at space saving, piping free, and simplification, but in the present invention, in order to make this point more thorough, it is preferable to make the following improvements.

The replenishment tank of the present invention is provided with a liquid level display means used when preparing the processing liquid. This liquid level display means may indicate the position of the finished amount of one treatment liquid, or may indicate the level of the dissolving or diluting water before adding the treatment compound.

Examples of this liquid level display means include, for example, a liquid level gauge with a mark A indicating the finished amount of processing liquid and a mark B indicating the amount of water required for preparing the processing liquid, as shown in FIG. It may be a mark attached to the inner wall of the replenishment tank, or a transparent or semi-transparent plate may be provided in a part of the processing tank so that the liquid in the replenishment tank can be seen. Alternatively, a sensor may be placed at a predetermined position and a lamp, buzzer, etc. may be used to notify the user.

-1- By providing the liquid level display means described above, the treatment J'
l! It is possible to easily and accurately prepare the liquid, but
This configuration can be used in combination with the previously proposed method for preparing a processing liquid using a metering cup described in the specification of Japanese Patent Application No. 59-69160. In this case, there is an advantage that in preparing the liquid using the metering cup, there is no need to plan every replenisher preparation to have an accurate finished amount from the beginning. That is, when one metering cup is used in common for two replenishment liquid preparations, in the case of several replenishment liquid preparations, it is possible to make two cups by refilling with water up to the above-mentioned cup A. becomes. This allows accurate and simple preparation.

In addition, the method for preparing the starting liquid using a metering cup described in the specification of Japanese Patent Application No. 59-69159 is similar to the method for preparing the starting liquid using a metering cup as described in the specification of Japanese Patent Application No. 59-58350. It can be used in a preparation method where it is used as a preparation container. In this case, accurate and simple preparation is possible even if the capacity of the limiting cup is slightly larger or smaller than the amount of water required for preparing the processing liquid.

Preparation of the processing liquid in the replenishment tank must be done with the lid covered in step 1 of inserting the replenishment liquid kit for another replenishment tank to prevent contamination due to liquid scattering.Color development of color paper When preparing a processing solution containing a part containing an emotive alcohol, such as a developer replenisher, add the entire amount of water necessary for preparing the processing solution using a measuring cup, and then It is better to add the alcoholic alcohol and stir it using the stirring means described in Japanese Patent Application No. 59-81692, and then add the rest of the alcoholic alcohol to form an oil. It has the advantage of not becoming

Furthermore, in this case, leave some water in the measuring cup,
By washing the insertion port with water after removing the replenisher kit, it is possible to prevent oxides from adhering to the insertion port.

Processing solutions that are relatively easy to mix and dissolve, such as color developing replenishers for color negatives and bleach-fixing replenishers for color papers, are divided into multiple parts due to their precipitation and stability.
First, supply all or half of the amount of water required for preparing the treatment solution in a quantitative container, and finish by adding notes one by one.
It is more convenient to finish by adding the remaining water and stir using the above-mentioned stirring means or the stirring means described in the specification of the present application since troubles such as precipitation do not occur during the preparation of the treatment liquid. In addition, in the case of color developer replenisher for color negatives, water is supplied using a metering cup at the beginning and end.
As mentioned above, it is more convenient to divide the replenishment kit into several times because oxides do not adhere to the replenisher kit insertion port.

In addition, like bleach replenisher and fixer replenisher for color negatives,
If the kit has a large capacity and is made up of one part, it is better to add the replenisher first using the Kinto, and then add water, as this will give a better stirring effect when adding water. It's convenient.

Furthermore, if the kit consists of one part and has a small volume, such as stable replenisher for color negatives (including draining replenisher for color negatives), the kit may be placed in a metering cup of water. If you add the replenishment solution directly and transfer it to the replenishment tank, 4. Yayoeo13
It is possible to prevent problems such as 4 degrees, 21 degrees, and 6 degrees, and it is possible to prepare the correct processing solution.

In this way, when mixing is relatively easy,
A simple stirring means is also not required.

In addition, in cases where the waterless washing stable replenisher for color paper is made up of multiple notes, each having a small volume, other parts may be added and mixed in one note. By adding the liquid to the replenishment tank afterward, you can prevent the above-mentioned liquid accumulation and adhesion accidents.

In addition, if water can be supplied by the metering cup separately at the beginning and end and mixed relatively easily, simple stirring is not necessary.

Regarding the preparation of the starting solution, in the case of a color developing stardough solution for color paper containing an emotive alcohol, it is described in the specifications of Japanese Patent Application Nos. 59-69158 and 59-58351. Apparatus and methods are used. That is, the start solution is circulated and mixed in the replenishment tank and sent to the processing tank, but in this case, it is not necessarily necessary to increase the amount of liquid to the specified level in the replenishment tank, and after transferring it to the processing tank, the kit is further mixed. You can also add a part of it or add water. Regarding the finishing method, the measuring cup method described in the specification of Japanese Patent Application No. 59-69159, the replenishing tank with a liquid level display means of the present invention, or the method described in Japanese Patent Application No. 59-58
A processing tank having a liquid level display means described in the specification of No. 351 is used, but these may be used in combination. For example, mix and prepare water in a metering cup with replenisher from the kit, transfer it to the treatment tank, add Nutata, and then add water with a metering cup up to the marked line in the treatment tank. By doing so, the capacity of the metering cup does not necessarily exactly correspond to the amount of water required for the final finishing, and even if there is some excess or deficiency, the metering cup can be used effectively.

A processing tank is preferably used for preparing a start solution other than a color development start solution for color paper. All processing tanks (including color paper color development tank) are manufactured by patent application 1983-1983.
It is preferable to have the liquid level display means described in the specification of the patent application No. 350, and it is preferable to use the measuring cup described in the specification of the patent application No. 59-69159. This is preferred for the same reason as in the case of preparing a color development start solution for paper. It is desirable to attach and detach the transport racks for all treatment tanks so that they do not get in the way when supplying kits and water. When preparing the starting solution, the solution may splash and contaminate other prepared processing solutions.
In order to avoid situations where you have to discard the starting liquid, in the case of starting liquid for color negatives, drain starting liquid,
In the case of a start solution for color paper, it is preferable to prepare the stable start solution, the fixing start solution, the bleaching start solution, and the color development start solution in this order: the stable start solution, the bleach-fix start solution, and the color development start solution. Further, it is preferable that the color development processing tank is provided with a cover to prevent contamination from occurring when a start solution other than the color development start solution is prepared. After all liquids have been prepared, attach all ranks and turn on the circulation pump.
If the mixture is stirred and dissolved under nitrogen, the starting liquid will be prepared in just the right amount below the overflow port. Water is then supplied by the fixing cup, then the kit, and finally again by the metering pump to the mark.

B4: Management of replenishment solution In order to prevent the replenishment tank from being emptied and the processing solution not being refilled into the processing tank, the lower position of the replenishment tank should be placed, for example. A sensor is installed in the tank, and when it detects that the remaining liquid has reached the amount required for at least one refill,
The notification should be made by means such as a buzzer or a panel display.

Furthermore, the lower end of each replenishment tank is preferably conical, and if a drain tank is placed at the end to allow the processing solution in the tank to be drained, it is possible to prevent oxidation, etc., especially when processing small quantities. It is convenient to replace the processing liquid even if a problem occurs.

B5: Replenishment tank location/installation structure, etc. The replenishment tank should be placed in parallel with the processing tank and on the side closer to the operator ("6.
001'""ゞ"601°゛19-It becomes possible to install the six devices by pressing them against a wall, for example, and it is also possible to perform operations such as installing the kit easily.

In order to improve workability, the replenishment tank including the circulation system pump and the like is constructed as a unit so that it can be pulled out from the entire apparatus. This configuration is also extremely effective during maintenance. In this case, the entire replenishment tank may be made into a unit, or may be made into individual units.

Further, for example, if only the stabilizing tank or only the large-capacity replenishment tank is fixed, and the other replenishment tanks are made into a unit and can be pulled out, the withdrawal operation is simple and advantageous.

In the above, the drawer mechanism can be designed in various ways,
It is possible to adopt door opening methods using hinges, double door opening methods, drawer methods using guide rails, etc. When using a hinge, it is desirable to provide a support structure such as a support rail to support the lower surface in order to prevent excessive weight from being applied to the hinge. This support structure may be provided on the lower side of the replenishment tank that is pulled out, or may be provided on the main body side of the automatic developing machine.

B6: Processing liquid circulation system The operation of the circulation system is automatically controlled for the purpose of reducing energy costs. That is, it performs controls such as starting the operation only when the color photosensitive material to be processed is set, starting the operation at the same time as the heater is activated when the temperature is below a certain level, and operating the heater intermittently. be.

When dissolving the start liquid in the treatment tank or filling the treatment tank with the hair-conditioned start liquid in the replenishment tank and operating the circulation pump, this is to prevent bubbles from forming and causing the liquid to burst and competition to occur. When attaching the circulation pipe 5 to the treatment tank 4, if the circulation pipe is a closed system, for example, as shown in FIG. This is not desirable as there is a risk that air may accumulate in this area.

However, in general, the processing solution in the processing tank is connected to a circulation pipe in order to improve the efficiency of the photosensitive filter. In this case, in consideration of filter replacement, the height of the wall of the filter box should be the same as the level of the processing liquid in the processing tank, and measures must be taken to prevent the processing liquid in the processing tank from flowing backwards when replacing the filter. In this case, it is unavoidable that a part of the circulation pump will be installed above the mounting position.

Therefore, in such a case, a cock is required to evacuate the air inside the filter box, which is extremely complicated to operate. These drawbacks can be solved by making the filter chamber an open system. From this point of view, first, the patent application 1983-6
In the specification of No. 9158, a configuration in which a liquid purification filter is arranged was proposed, and specifically, the configuration is as shown in FIGS. 4 and 5. That is, the filter mechanism 6 is housed in a box 7 fixed to the upper side of the processing tank 4 . A specific example of the configuration of the filter mechanism 6 is shown in FIG. 5, in which a cylindrical filter member 6B is attached to stoppers 6C and 6D on a base 6A that is hollow and has many through holes around it.
It is attached in a pressed manner. The filter mechanism 6 is attached to the upper end of the pipe 5 that is connected to the bottom surface of the box 7, and is kept watertight so that the processing liquid does not directly flow into the pipe 5 without passing through the filter mechanism 6. It needs to be attached to. Further, the liquid level of the processing liquid is controlled so that it is always above the filter mechanism 6. If a part of the filter mechanism 6 were to protrude above the level of the processing liquid, there is a risk that air would be drawn in, resulting in liquid splashing and oxidation of the processing liquid due to the air. Various known sensor means can be used to detect the liquid level position, and when a malfunction is detected,
In addition to being notified by a buzzer, panel display, etc., the operation of the pump 8 is stopped. Note that the liquid level positions of the processing liquid in the processing tank 4 and the box 7 are the same, and the liquid level sensor may be placed in either location. Further, the filter mechanism 6 can be easily taken out by opening the lid 7A of the box 7.

9 is a temperature adjustment sensor, which is located inside the box 7'.
j:&fiit6:&i,:yo0.5-2□,ka,5
Good and accurate temperature detection is possible. 7B is an opening for setting a replenishment pipe 10 that supplies replenishment liquid from the replenishment tank, and it is easier to attach and detach the replenishment pipe 10 than to directly supply replenishment liquid to the processing tank 4. Since it is always introduced into the processing tank 4 after passing through the filter mechanism 6, even if foreign matter is mixed in, it is possible to prevent an accident from occurring.

6 to 8 show the construction of a processing liquid circulation system that is particularly effective when performing color development processing. That is, the processing liquid circulated by the pump 8 from the processing tank 4 via the filter mechanism 6 is introduced into the processing tank 4 again through the pipe 5, but especially in the case of color developing solution, the processing liquid is simply passed through the processing tank. 4, as shown in the figure, a terminal fitting 12 having a large number of pores 11 of 0.5IIlva to 5IllII+, preferably about 2m1m, is attached to the end of the pipe 5, and the treatment is discharged from these pores 11. The liquid is sprayed onto the color photosensitive material to be processed.
The pores 11 may be configured simply as through holes or may be configured as nozzles. Although the number and arrangement of the pores 11 are not limited, it is preferable that the pores 11 be sprayed in, for example, a staggered pattern at at least three locations in the width direction of the color photosensitive material to be processed. The terminal device of the present invention must be used with all of its pores 11 immersed in the bath liquid. The above structure is particularly effective in preventing uneven stirring during color development processing.

Although the above-described spraying mechanism is connected to the circulation of the processing liquid by the circulation pump 8, the spraying mechanism may be provided independently.

Furthermore, in addition to the above, in order to achieve energy savings, it is also desirable to operate the spraying mechanism only when the color photosensitive material is being processed in the processing tank.

B7: Temperature adjustment Especially when used in a cold region, there is a risk that the processing liquid may freeze and the components may precipitate.
The temperature adjustment mechanism is activated when the temperature reaches a predetermined temperature, such as below C, 0° C. or above, preferably 3° C. or above, more preferably 5° C. or above. In this case, it is desirable to operate the circulation pump at the same time to prevent local deterioration of the liquid. Also,
In this case, it is desirable to arrange the temperature sensor at a position where the average temperature of the processing liquid in the processing tank can be measured. Further, it is preferable to separate the switches of the automatic developing machine into ON/OFF, cold region, and timer switches. Further, for the purpose of shortening the heat-up time, it is desirable to adjust the heater output during heat-up and during temperature control by, for example, changing the number of heaters to be turned on.

Furthermore, in this invention, regarding cooling of the processing tank/replenishment tank, for example, if water is stored in an unused replenishment tank or a dedicated tank, and a cooling method using this stored water is used, cooling water as in the conventional case can be used. It is not necessary to use . The accumulated water may be treated with an anti-spill agent, subjected to a magnetic field (see Patent Application C filed on June 13, 1980), or treated with ultraviolet irradiation (June 1, 1980).
(See Patent Application A of the 3FI application), it can be used for a long period of time, but a stabilizing liquid can also be used, and in this case there is no need to prepare water for cooling. This can be done by cooling the accumulated water with a fan or a refrigerant and guiding it to the inside or outside of the treatment tank through a pipe.

Furthermore, there is no need to use cooling water even in the case of a cold tofu system, such as in a refrigerator. In this case, the processing liquid may be directly cooled, or the air inside the machine may be cooled. In addition to methods that utilize temperature differences between adjacent tanks for cooling, etc., methods that simply exhaust the air inside the aircraft using a fan are also effective.

B8: Replenishment of replenisher solution According to the present invention, for example, the volume ratio of the processing solution in each processing tank is [
CD tank] : [BF tank] : [ST tank]
= [1-5 to 2.5 units: [1]: [2 to 3] is preferable, and when the ST tank is divided into two or more, the volumes of processing liquid should be approximately the same. good.

Replenishment of the stabilizing solution is performed in one treatment area rather than continuous replenishment in small intervals.
"1"'L7:I""M & * mjfn It t
Z= :”IAH*Lbz.

For example, color paper E version (82mm x 117mm)
It is preferable to carry out intermittent dog supplementation by calculating the amount of 2 to 3 mσ per 8-plate sheet every time 70 to 120 sheets (preferably 80 to 100 sheets) are processed.

The processing amount of the photosensitive material can be calculated in any way. For example, if the transportation speed of the photosensitive material is kept constant and the width of the processed photosensitive material '1' and the processing time are detected and calculated, the processing area of the photosensitive material can be calculated. can get.

The replenishment amount of the stabilizing solution in the present invention is, for example, [CI] replenisher]: [ST replenisher mite] = [11:
[1-4], more preferably [+]: [1,5-3]
It is better to

Furthermore, when recharging the replenisher, it is desirable to set it to two or more categories depending on the throughput. For example, a standard throughput is set based on an average daily throughput of 15 films (converted to 24 films) that continues for two weeks or more, and anything less than this is defined as a low throughput, and replenishment is performed. It is desirable to provide different amounts of liquid to be refilled. The reason for doing this is that especially in the case of a low throughput, the renewal rate of the processing liquid in the processing tank becomes low or the rate of evaporation becomes large.

The replenishment amount for low throughput is set at 10% of the standard replenishment amount.
It is determined by increasing the number.

The replenisher for low throughput is prepared by diluting the standard replenisher for evaporation, for example to 150%, but even in this case, the amount of chemicals to be refilled remains the same for the treatment. It is advantageous in terms of cost. However, if the deterioration of the solution is significant due to the long stagnation time of the processing solution in the processing tank due to the low processing amount, use the standard processing amount replenishment solution as is and increase the replenishment amount. Must be greater than the standard replenishment amount. Of course, in this case, you can use a combination of both, for example, by diluting the replenisher to 150% and adding 200% of the standard replenishment amount.
% may be added.

The treatment liquid is usually managed by Control Nutrip, but it is preferable to use a simple analysis method to analyze specific components in the treatment liquid, learn the condition of the treatment liquid, and then take measures. used. For example, this method involves detecting the bromide ion concentration during photochromic development and adjusting the amount of replenisher based on the analysis results, and detecting the iron ion concentration in the color developing solution and checking for contamination in the bleach-fix solution. A method of detecting sulfite ions and investigating the cause according to the analysis results, a method of detecting the concentration of sulfite ions other than the bleach-fix solution, and adding an additive containing sulfite ions according to the analysis results, etc. There is. There is also a method of detecting the concentration of sulfite ions in the first tank, such as the stabilization tank, where sedimentation 2 is particularly likely to occur, and adding an additive containing sulfite ions according to the analysis results. In this case, commercially available sulfite test paper is used. in this case,
If necessary, it is preferable to add additives to the bleaching bath for better effect.

B8; Waste liquid treatment The automatic developing machine to which this invention is applied does not require washing water, so it can be installed in any number of pairs, but the waste liquid of the processing liquid must be treated in some way. Regarding this point, we proposed the use of a waste liquid tank in the specification of the patent application (B) filed on June 13, 1980.
A specific example thereof is configured as follows. That is, in FIG. 9, a waste liquid receptacle 14 having a lid is provided on the flat surface of the rectangular waste liquid recovery tank 13 without protruding above the flat surface.
is provided. Reference numeral 15 denotes a handle, and an exhaust ``116'' is provided at the opposite position.

Since the tank 13 is constructed as shown in the drawing, six tanks can be easily attached and detached to predetermined positions within the apparatus using a cassette method. Further, it is desirable to provide two types of tanks 13, one for a color developing solution and one for a stable/bleach-fixing solution. However, when attempting to recover silver from waste liquid, the former waste liquid does not contain silver, so mixing the two waste liquids is not preferable from the standpoint of reducing recovery efficiency. It is.

Furthermore, the amount of waste liquid accumulated in the tank 13 is notified mechanically by means such as weight detection, or by electrical means such as a buzzer or panel display, thereby preventing accidents such as overflow of waste liquid. be done.

-Color 1 □ 2nd [. 1□ C1: Conveying means other than endless belts We proposed the use of endless belts as a means of feeding and conveying color photosensitive materials into processing tanks. As a result of the circulation, a small amount of different processing solutions mix together, which not only has a negative effect on the processing solution composition, but also causes air to be trapped in the processing solution by the belt, which facilitates air oxidation. There are some difficulties. In order to solve this problem, it is desirable to adopt a roller transport method, short leader method, or other conveyance method.

C2: Drive control The drive is automatically controlled for the purpose of energy saving and prevention of air being mixed into the liquid due to idle operation of the conveyance system. It is desirable to drive the conveyance system intermittently only when it is detected that a color photosensitive material has been loaded.

In addition, if the - part of the upper roller is out of the liquid level, the processing liquid attached to the roller will dry up and harden, causing damage to the photosensitive material. It is desirable to drive the rollers intermittently even when they are not in use.

C3: Drying of color photosensitive materials Since a certain amount of time is required from the start of processing to the completion of processing of color photosensitive materials, controlling the drying device according to the position information of the color photosensitive materials reduces processing costs and is sufficient. It is desirable to provide dryness.

For example, normally the heater is turned off and the completion time is calculated from the processing start information, or the temperature of the drying chamber is increased by preheating the drying chamber in advance of the scheduled completion time according to the position information of the color photosensitive material 1. ), it is possible to significantly save power consumption by starting drying according to the processing completion information.

[Effects of the Invention] Since the present invention is configured as described above, when applied to a waterless washing type automatic developing machine for color photosensitive materials, the above-mentioned technical problems can be solved.
