Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic developing machine and processing method for silver halide photosensitive materials, and more particularly to a method and a supply amount of evaporation correction water in an automatic developing machine and processing method for color photosensitive materials.

[0002]

2. Description of the Related Art Conventionally, a silver halide light-sensitive material is processed by processes such as development, desilvering, washing and stabilization after exposure. Processing is usually carried out by an automatic processor (hereinafter sometimes abbreviated as automatic processor), in which case a method is generally used in which the replenisher is controlled to keep the activity of the processing solution constant. It has been. The role of the replenisher is to dilute the eluate from the light-sensitive material, replenish the consumable components in the processing solution, correct the evaporated water, etc. It was a system that discharged a large amount.

However, in recent years, regulations on the disposal of waste liquids and plastic materials have been increasing worldwide, and the development of a system in which the waste liquid of the developing machine is substantially reduced to zero and a plastic bottle for liquid agent is not required is developed. It has been demanded.

In addition, at minilab stores and the like, which have been rapidly increasing in recent years, in order to reduce costs and solve labor shortages, part timers without specialized knowledge are being developed. Moreover, when the amount of treatment per day is small, for example, when the average amount of treatment is about 5 color negatives (24Ex) / day, the equipment is downsized, so that the fatigue of the treatment liquid and the amount of evaporated water over time are relatively small. The impact will be greater.

In order to cope with these changes in the environment, it is necessary to make a system in which the waste liquid of the automatic developing machine is substantially zero or close to it, more stable than the conventional one, and easy to maintain. In particular, in order to substantially reduce the amount of waste liquid in the automatic processing machine, it is necessary to lower the drug concentration in the treatment liquid, but there are still measures to reduce the drug concentration and to make a stable system. The current situation is that they have not been found.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems. Specifically, it is a self-developing machine system that uses a low-concentration processing solution, and is stable, and the amount of replenisher solution is Therefore, the amount of waste liquid is small, the structure of the equipment is simple, and the system is easy to maintain. Furthermore, it is the development of a processing method which has a low replenishing amount of an automatic processing machine and is less affected by the mixing of the processing solution in the previous process, and which is free from stains and backside stains of the processed photosensitive material.

[0007]

The object of the present invention is achieved by adopting the following constitution.

That is, in the automatic developing machine for photosensitive materials,
It is equipped with a series of treatment tanks in which the treatment liquid circulates, and when correcting water is supplied according to the evaporation of water, it is collectively supplied to the most downstream tank, and the amount of corrected water is within the range of the following formula. And a processing method using the same.

0.0 <(evaporated water amount-corrected water amount) / (sensitized material treatment amount × replenishment amount) <0.3 Evaporated water amount: Evaporated water amount from a series of treatment tanks per day (ml) The amount of evaporated water is 25 ° C in the external environment, 5
Evaporated water amount from a series of treatment tanks at 0% RH, amount of evaporated water when adjusting to the temperature of a predetermined treatment (measured value ml / hr) 10
Time and amount of evaporated water when temperature is not adjusted (measured value ml / h
r) 14 hours were added to make one day's worth.

Compensation water amount: Compensation water amount to be supplied per day (ml) Sensitive material processing amount: Photosensitive material processing amount per day (m ² ) Replenishment amount: Processing liquid added for processing 1 m ² of photosensitive material Amount of water (ml) However, when the solid processing agent is directly charged into the processing tank, the replenishment amount is the sum of the volumes of the solid processing agent and the replenishing water replenished with respect to 1 m ² of the light-sensitive material.

With the above construction, it is not necessary to install a device for supplying the correction water for each of a series of treatment tanks in which the treatment liquid flows, and the mechanism of the automatic processing machine is simplified accordingly. Not only does the price decrease and the maintainability improve, but when the pretreatment agent in the most downstream tank, for example, the stabilizing solution tank is divided into several tanks, the concentration of the fixing agent mixed in the most downstream tank is extremely low. You can hold it down.
When adopting these methods, it is desirable that the automatic machine has a counter current mechanism. In addition,
The series of processing tanks having circulation refers to a plurality of tanks having some mechanism for moving a liquid between the tanks, and may be different processing tanks such as a fixing tank and a stabilizing tank. The means for pouring may be a method utilizing the difference in water level of the treatment layer, or a method of using a bellows horn or the like to draw out a part of the treatment tank and pour it into another tank. The most downstream tank is the final tank in the series of processing tanks.

As a technique related to the configuration of the present invention, for example, as in JP-A-7-56309, correction water is collectively supplied to the most downstream tank, and as in JP-A-4-1756, the amount of evaporated water is estimated in advance. There was a method of adding the corrected amount of water. However, it was not known that it would be good to use a combination of these for cost performance and compactness of an automatic processing machine.

Further, when the continuous treatment is carried out with such a combination, the concentration of the treating agent is currently being lowered due to pollution or the like, and therefore, it is easily affected by the contamination of the treating liquid in the preceding step. In many cases, it causes stains and deteriorates the storage stability of the processing liquid. This effect increases at an accelerating rate when the number of processes per day is small. It was also found that the concentration of the treatment liquid tends to be too thin. When the concentration of the treatment liquid unexpectedly falls below the specified level, the performance is rapidly deteriorated due to the treatment liquid that is originally low in concentration, and the expected performance is often not obtained.

Alternatively, in the current method of adding a fixed amount of evaporation correction water to each tank when the liquid level is lowered by using the liquid level sensor, the liquid level is replenished independently by the replenishment of the processing liquid. The decrease is difficult to detect, and make-up water is hardly supplied, which further undesirably concentrates the liquid composition.

It was found that the processing amount of the light-sensitive material and the replenishing amount of the processing solution therefor must be within a certain range, and the above invention was made.

Note that (evaporated water amount-corrected water amount) / (sensitized material processing amount × replenishment amount) may be hereinafter referred to as a coefficient k. The coefficient k is more preferably 0 <k <0.3 or 0 <k <0.2.

The present invention can be applied to the processing of various silver halide light-sensitive materials, particularly color light-sensitive materials such as color negative films and color photographic papers.

The bleach-fixing tank may be composed of a mixture of the bleaching tank overflow solution and the fixing tank overflow solution, in which case the bleaching tank-bleach-fixing tank-fixing tank is arranged in this order. Is preferred.

In the present invention, it is necessary to directly pump out the processing liquid from the washing bath or the stabilizing bath by means of a pump or the like and introduce it into the fixing bath or the bleach-fixing bath, but preferably the fixing bath or the bleach-fixing bath.

The present invention will be described in detail below with reference to examples, but the embodiments of the present invention are not limited thereto.

Embodiment 1 Next, an embodiment of the automatic developing machine for silver halide photographic light-sensitive material of the present invention will be described with reference to the accompanying drawings.

An example of an automatic developing machine to which the present invention can be applied will be described with reference to the drawing of FIG. FIG. 1 is a schematic configuration 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 portion of the photographic printing machine B, a magazine M containing a roll of photographic paper which is an unexposed silver halide photographic photosensitive material is set. The photographic printing paper pulled out from the magazine is cut into a predetermined size through the feed roller R1 and the cutter section C to become a sheet-shaped printing paper. This sheet-shaped photographic paper is a belt conveying means B.
The image of the original image O is exposed by the light source and the lens L in the exposure section E by being conveyed by e. The exposed sheet-shaped photographic paper is further provided with a plurality of pairs of feed rollers R2, R3.
It is conveyed by R4 and introduced into the automatic developing machine A. In the automatic developing machine A, the sheet-shaped printing paper is a processing tank which is a color developing tank CD, a bleach-fixing tank BF, a stabilizing tank S1,
The rollers S1 and S3 (substantially three-bath processing tank 1 ) are sequentially conveyed 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-mentioned treatments is dried in the drying unit 5'and discharged outside the machine.

The alternate long and short dash line in the figure indicates the transport path of the silver halide photographic light-sensitive material. Further, in the embodiment, the photosensitive material is introduced into the automatic developing machine A in a cut state, but it may be introduced into the automatic developing machine A in a strip shape. 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 processor A according to the present invention may be configured integrally with the photographic printer B or may be the automatic processor A alone. Needless to say, the silver halide photographic light-sensitive material processed by the automatic processor A according to the present invention is not limited to exposed photographic paper, and may be exposed negative film or the like. Further, as an explanation of the present invention, a color developing tank CD, a bleach-fixing tank BF, a stabilizing tank S1, S2, S
The process is performed on the automatic processor A having the processing bath 1 having a substantially three-bath configuration having the number 3, but is not limited to this.
The present invention can be applied even to an automatic developing machine having a substantially four-bath structure including a color developing tank, a bleaching tank, a fixing tank, and a stabilizing tank.

Each of the color developing tank CD, the bleach-fixing tank BF, and the stabilizing tank S3 is provided with a constant temperature tank which is a solid processing agent charging section and is in communication therewith.

FIG. 2 is a cross-sectional view of the processing agent charging section and the processing agent supply means of the bleach-fixing tank BF which is a processing tank in the II section of the automatic processor A of FIG. In this embodiment, a solid processing agent replenishing device is also installed in the color developing tank CD and the stabilizing tank S3 so that each solid processing agent can be charged into each processing tank. That is, 3A, 3 in FIG.
B and 3E are solid processing agent replenishing devices, 3A is a color developing tank CD, and 3B is a bleach-fixing tank BF.
A bleach-fixing replenishing tablet is provided at 3E, which is a solid processing agent replenishing device for charging the stabilizing replenishing tablet into the stabilizing tank S3. Therefore, the color developing tank CD and the stabilizing tank S3 have the same configuration as the bleach-fixing tank BF. Therefore, when the processing tank 100 is described below, all of the color developing tank CD, the bleach-fixing tank BF, and the stabilizing tank S3 are used. I will point it. It should be noted that, in the figure, a conveying means for conveying the photosensitive material is omitted for easy understanding of the configuration. Further, in this example, a case where tablets are used as the solid processing agent will be described. The replenishing device of the present invention can also be used for packaging of granules and powders other than tablets.

In FIG. 2, a processing tank 100 for processing a photosensitive material is a solid processing agent charging section 70 for supplying a solid processing agent (tablet) J integrally provided on the outside of a partition wall forming the processing tank 100. And a constant temperature bath 700. The processing bath 100 and the constant temperature bath 700 are partitioned by a partition wall 71A having a communication window 71 formed therein so that the processing liquid can flow. Since the solid processing agent injection part 70 provided above the constant temperature bath 700 is provided with the enclosure 75 for receiving the solid processing agent J, the solid processing agent J remains in the solid state in the processing tank 1.
Never move to 3. It should be noted that the enclosure 75 allows the processing liquid to pass therethrough, but the solid processing agent J must pass through a mesh or filter shape that cannot pass until the dissolution.

The cylindrical filter 72 is replaceably provided below the constant temperature bath 700, and has a function of removing insoluble matter such as paper waste in the treatment liquid. This filter 72
The inside is communicated with the suction side of the circulation pump 74 (circulation means) via a circulation pipe 73 provided through the lower wall of the constant temperature bath 700.

When the processing tank shown in FIG. 2 is a fixing tank or a bleach-fixing tank, the processing liquid pumped out from the washing tank or the stabilizing tank is introduced near the position where the replenisher is replenished. Introduced by. This allows good dissolution of the tablet.

The circulation system is composed of a circulation pipe 73 forming a liquid circulation passage, a circulation pump 74, a processing tank 100 and the like. The other end of the circulation pipe 73 that communicates with the discharge side of the circulation pump 74 penetrates the lower wall of the processing tank 100 and communicates with the processing tank 100. With such a configuration, when the circulation pump 74 is operated, the processing liquid is sucked from the constant temperature bath 700 and discharged to the processing bath 100, and the processing liquid mixes with the processing liquid in the processing bath 100, and returns to the constant temperature bath 700 again. The cycle of entering will be repeated. The flow rate of the circulation flow 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 does not need to be limited to the direction shown in FIG. 2 and may be the opposite direction.

The waste liquid pipe 79 is used to overflow the processing liquid in the processing tank 100 and drop it into the waste liquid tank WT. The liquid surface level is kept constant, and the liquid is attached to the photosensitive material from another processing tank. Stored components and components leached from the light-sensitive material are stored, which helps prevent them from increasing.

The rod-shaped heater 76 is arranged so as to penetrate the upper wall of the constant temperature bath 700 and be immersed in the processing liquid in the constant temperature bath 700. The heater 76 heats the treatment liquid in the constant temperature bath 700 and the treatment bath 100. In other words, the heater 76 keeps the treatment liquid in the treatment bath 1 within a temperature range (for example, 20 to 55 ° C.) suitable for the treatment. It is a temperature adjusting means. Further, since the heater 76 is disposed in the vicinity of the position where the solid processing agent is charged, it has the effect of promoting its solubility.

The processing amount information detecting means 81 is an automatic developing machine A.
Is provided at the entrance of the and used to detect the throughput of the photosensitive material to be processed. This throughput information detecting means 81
Has a plurality of detection members arranged in the left-right direction and functions as an element for detecting the width of the photosensitive material and for counting the detected time. Since the conveying speed of the photosensitive material is mechanically set in advance, the processing area of the photosensitive material can be calculated from the width information and the time information. The processing amount information detecting means 81 may be any one capable of detecting the width and the conveyance time of the photosensitive material such as an infrared sensor, a micro switch, an ultrasonic sensor. Further, in the case of a printer which can indirectly detect the processed area of the photosensitive material, for example, in the case of a printer processor as shown in FIG.
Alternatively, the number of processed photosensitive materials having a predetermined area may be detected. Furthermore, the detection timing is before processing in this example, but after processing,
Alternatively, it may be during the immersion in the processing liquid (in such a case, the position where the processing amount information detecting means 81 is provided can be appropriately changed to a position that can be detected after processing or a position that can be detected during processing). Furthermore, as the information to be detected, in the above description, the processing area of the photosensitive material is described, but it is not limited to this, and the processed area is
Alternatively, it may be a value proportional to the processing amount of the photosensitive material being processed.

Further, it is not necessary to provide the processing amount information detecting means 81 for each of the processing tanks CD, BF, S1, S2, S3, and it is preferable to provide one for each automatic developing machine A. Reference numeral 82 is a processing amount supply control means for receiving the signal from the processing amount information detecting means 81 and controlling the processing amount supply of the processing agent.

The solid processing agent replenishing device 80 is set above the processing tank of the photosensitive material processing device for processing the exposed photosensitive material, and contains a container 88, a container loading means 84, a supply means 85, and a processing agent supply plate. It is composed of 851, a notch portion 852, a driving means 86, etc., and is sealed by the inside of the upper cover 801. The upper cover 801 is swingably connected to the main body 101 that houses the processing bath 100 and the constant temperature bath 700 by a support shaft 802 at the back of the main body, and the upper cover 801 is lifted in the direction of the chain line A in the figure. By greatly opening the front surface and the top surface on the operator side, the solid processing agent replenishing device 80 can be inspected and the filter 72 can be replaced.

A skylight 803 is swingably connected to a part of the upper surface of the upper cover 801, and the skylight 803 is opened in the direction of the alternate long and short dash line B in FIG. Exchange.

FIG. 3 shows examples of various shapes of the tablet type solid processing agent J. 3 (A) is a cross-sectional view of a flat solid processing agent J having a circular flat surface and a rounded chamfer (r) at the corners, and FIG. 3 (E) is a sectional view of the solid processing agent J. It is a perspective view. FIG. 3 (B) is a cross-sectional view of a drum-shaped solid processing agent J having a circular cross section, the upper and lower surfaces of which are flat and the circumferential surface of which has a convex radius (R). FIG. 3C is a cross-sectional view of J, which is a go-stone solid processing agent having a circular cross section and upper and lower surfaces having a spherical shape. FIG. 3D is a cross-sectional view of a donut-shaped solid processing agent J having a hollow hole.

Next, the solid processing agent replenishing device 80 for replenishing the processing tank 1 with the solid processing agent (hereinafter also referred to as a tablet) J having the shape shown in FIG. 3 will be described with reference to FIG.

In FIG. 2, the tablets J are stored in the storage container 88, and the skylight 803 is shown in the figure as indicated by the chain line B.
The storage container 88, which is opened in the direction, and in which the tablets J are stored, is inserted by the operator's hand in the direction of the outlined arrow C and loaded into the storage container loading means 84. And storage container loading means 8
4, the storage container 83 is rotated in the direction of the outlined arrow D, and the loading of the storage container 83 into the storage container loading means 84 is completed. In this state, the storage container 83 is in an inclined state with the left side facing down as shown in the figure, and thus the tablet J stored therein is in a state in which it is urged to move to the left by gravity.

Next, the processing amount supply control means 82 is operated by the information of the processing amount information detecting means 81 based on the processing amount of the photosensitive material, and the motor M of the driving means 86 is driven. The processing agent supply plate 851 in the supply means 85 driven by is rotated clockwise.

When the processing agent supply plate 851 is rotated and the positions of the tablet J and the notch section 852 coincide with each other, the tablet J has the notch section 852.
It can be rolled into 52. Therefore, in such a state, the tablets J roll into the notches 852 of the treatment agent supply plate 851, and the row of the tablets J moves to the left by exactly one tablet. Then, when the processing agent supply plate 851 further rotates and the notch 852 is directed downward, the inside tablet J is guided by the chute 77 in the direction of the arrow E shown in the figure and drops into the enclosure 75 of the solid processing agent input part 70. . Then, as described above, the tablet J is dissolved in the enclosure 75 and mixed into the treatment liquid to replenish the treatment liquid.
