Description
The present invention relates to a photosensitive material developing apparatus, and more particularly, to a technique for accelerating oxidation of a rinse liquid having bleaching performance and minimizing reduction in the ability of the rinse liquid.
The photographic processing of color silver halide photographic material negative consists of color development, bleaching, fixing or bleaching, stabilization or washing. If the rinsing liquid (processing liquid), especially the rinsing liquid including bleaching, is not properly oxidized, a phenomenon of degradation of the rinsing liquid will soon occur. If such a situation persists, the number of times development is completed will be reduced as a result. Therefore, in order to prevent the degradation phenomenon of the rinse liquid, there are employed devices such as those employed in Konika KP50QA and Noritsu V50, which increase the chance of the rinse liquid contacting the atmospheric oxygen by feeding air into the rinse liquid through an air pump, or by spraying the rinse liquid from a spray type nozzle into the atmosphere.
However, air is added to the rinse solution due to the above-mentioned air delivery type and shower type devices using an air pump. Thus, bubbles are generated. The bubbles overflow the outside of the container so that its surroundings are contaminated. In addition, if the rinse liquid containing the overflowing bubbles enters the nearby rinse liquid, the rinsing performance will be a fatal problem.
In addition, in the case of the air pump type device (air pump type), the air pump needs to be separated, and in the case of the shower type device (showitrype), the shower container needs to be separated. Therefore, the cost is increased and the apparatus is enlarged.
In the case of the spray type, circulation is required for agitating the rinse liquid and spraying the rinse liquid, and if the flow rate and circulation amount of agitation are small, the agitation action is deteriorated. To avoid the above problems, a powerful pump is required. Therefore, the cost of the apparatus is increased and the downsizing of the apparatus is hindered.
An object of the present invention is to stabilize the developing performance and to extend the life of the developing liquid by properly oxidizing the developing liquid and to provide a photosensitive material developing apparatus which can minimize the above-mentioned disadvantages and problems which have hitherto been caused.

Fig. 1 is a side sectional view of the photosensitive material developing apparatus of the present invention. Fig. 2 is a front sectional view of a bleaching component thereof.
The developing apparatus 100 is used for developing a silver halide photosensitive material for a color negative film, and is composed of aphotosensitive material supply part 10, a color developing part 110, a bleaching part 120, a fixing part 130 and a stabilizing part 140 which have been exposed in a cassette, and a part for replenishing a developing solution into a developing container in each developing part, and a developing solution circulating means. In addition, a drying member 150 is provided. Thus, the photosensitive material developing device is formed.
A bleaching container is provided instead of the separate bleaching container and fixing container in accordance with the kind of the color photosensitive material.
In this example, an oxidation acceleration part 126 is provided in the bleaching vessel 121 in the bleaching part 120 for accelerating oxidation by the rinse liquid contacting the atmosphere in the flow circuit. In addition, a rinse liquid circulating means is provided for high-speed flowing of the rinse liquid through the above-mentioned accelerated oxidation part 126, and also for uniform agitation of the rinse liquid in the container.
In the bleaching vessel 121 of the bleaching unit 120, the frame 129 is immersed in the liquid medicine. The photosensitive material is bleached while being conveyed along a conveying roller 129A on the above-mentioned frame 129 in the above-mentioned container 121A, and a container 121B provided with a built-in filter 124 and a heater 125 is connected to the container 121A through an oxidation acceleration part 126. The outside of the above-mentioned containers 121A and 121B is connected to a pump 122 (circulation device) and a pipe 123 (circulation circuit) for forming a circulation circuit. As described above, the bleaching liquid medicine in the bleaching container 121A is agitated in the container so as to form a uniform liquid medicine. In summary, the bleaching solution flows through the oxidation accelerating member 126 of the shallower bottom portion at a high speed. While increasing the contact performance with the air and being acted upon by the heater 125 for temperature control and maintaining the cleaning rinse in the filter 124, the bleaching liquor is circulated by the pump 122.
In the accelerated oxidation section 126, the liquid surface thereof is in contact with air almost in the same condition as that of the above-mentioned containers 121A and 121B. The bottom of the oxidation acceleration part 126 is shallow where the flow rate is 1 × 103Mm/min or greater. If the flow rate is 1X 103A millimeter/minute or more, a good effect can be obtained. In addition, the flow rate was 2X 103Preferably, mm/min or more, 5X 103Millimeter/minute or more is most preferred.
In the oxidation-accelerated component, the upper portion exposed to the atmosphere, i.e., the surface area contacting the atmosphere, is preferably 1,000 mm2. Further, the surface area of the upper portion exposed to the atmosphere is preferably 2,000 mm2. Incidentally, "exposed to the atmosphere" means that the surface of the rinse liquid is in contact with the atmosphere. Even if a cover is placed on the surface of the liquid of the rinsing liquid, this is allowed if the atmosphere contacts the surface of the rinsing liquid.
In addition, it has been proved that if the "surface area X flow rate" (in transit, with the bleaching agent) of the washing liquid passing through the accelerated oxidation part is 2X 106Millimeter3Permin, an effect of accelerating oxidation was observed.
It is preferable that the bottom of the oxidation acceleration part is not flat but is provided with a corrugated portion 127 as shown in the partially enlarged views of fig. 3 and 4. In addition, the corrugated portion (protruding portion 127A) may protrude above the liquid surface, as shown in the enlarged portion of FIG. 4.
Since the turbulent flow further promotes the accelerated oxidation, the effect thereof is excellent.
The above example is only one of the effective examples. Other examples are described below. Several protrusions are arranged at the bottom of the oxidation acceleration component, and the height of the protrusions is higher than the flowing depth of the liquid medicine. For example, the protrusions are 8X 1X 20 (mm).
Generally, a bleaching chemical has an action of converting silver in a developed silver image into silver halide, and utilizes an oxidizing action of a bleaching agent on silver. As bleaching agents, ferricyanide and the ferrate of aminopolycarboxylic acids such as the ferrate of EDTA (ethylenediamine tetraacetic acid) and the iron salt of the ferrate of 1, 3PDTA (1, 3-propylenediamine tetraacetic acid) are used, wherein monohalogenated substances are used as bleaching accelerators. The silver salt produced by oxidation by bleaching becomes silver halide.
The above reaction is carried out to obtain Fe3+To Fe2+The following formula:
Fe2+the concentration of (b) is the concentration of the double salt of ferrous iron. Fe3+The concentration of (b) is the concentration of the double salt of iron.
The standard for good bleaching power is a concentration of the double salt of iron of 16.5 g/l. In order to make the bleaching power constant, it is necessary to make the concentration of the double salt of iron 16.5 g/l or less even after developing 100 rolls of 24EX135 type film.
With respect to the above-mentioned bleaching agents, it is intended to replace the ferricyanide from which the Cyanogen (CN) is removed with a double salt of iron of the aminopolycarboxylic acid from which the cyanogen is not removed. However, the oxidation performance of the iron double salt of aminopolycarboxylic acid is inferior compared to ferricyanide. Thus, the double salt of iron of aminopolycarboxylic acid is disadvantageous for use in color films having a large amount of silver, although it is advantageous for color papers having a low silver consumption. However, from the viewpoint of environmental protection, an emulsion for reducing the silver content is being used in color films. Under such conditions, bleaching will be carried out gradually with the iron double salt of the aminopolycarboxylic acid. However, the disadvantages of the oxidation reaction of iron salts of aminopolycarboxylic acids remain under the above-mentioned conditions. It is therefore an object of the present invention to provide an apparatus capable of efficiently oxidizing without increasing the cost in accelerating the oxidation reaction, which promotes a low oxidation reaction mechanically by using an iron salt of aminopolycarboxylic acid and does not contaminate the surroundings of a vessel for rinsing by sputtering.
In other words, an oxidation accelerating member for achieving the object of the present invention is provided in the bleaching vessel 121 or the bleaching vessel.
To accelerate oxidation as quickly as possible, the surface area of the oxidation acceleration member 126 contacting the atmosphere is increased by increasing the flow rate. In order to achieve contact with the atmosphere in the oxidation acceleration member, a corrugated portion 127 is formed at the bottom of the fluid circuit or a protrusion portion 127A pushing up the surface of the liquid so as to generate turbulence is provided.
In addition, an oxidation acceleration member may be provided in a part of the circulation circuit, and the oxidation acceleration member may not be provided in the flushing container. "disposed on a portion of the circulation circuit" includes a separate container in a portion of the circulation circuit separate from the rinse container, which is identified as an oxidation acceleration component.
Examples
The air oxidation rate constant was determined according to the following examples and comparative examples. In addition, according to the representative examples and comparative examples, the gradually decreasing range of the concentration [ g/l]of the complex salt of iron was measured after washing 10 volumes, 30 volumes, 60 volumes, and 100 volumes, respectively, in one day.
According to the examples and comparative examples, the contamination around the container for rinsing after rinsing 100 rolls of 24EX135 type rubber roll was examined.
The "air oxidation rate constant", denoted K0Meaning that Fe is added2+The logarithmic value of the concentration, i.e. the concentration of the complex salt of iron, plotted against time in days, is a slope between time (abscissa) and the logarithmic value (ordinate).

(conclusion)
Table 1 shows the results. Fig. 5 shows a graph thereof.

According to comparative examples 1 and 2, the concentration of the double salt of iron becomes gradually smaller and larger than 16.5 g/l after developing 100 rolls of film, which is not suitable for practical use. According to comparative examples 3 and 4, the generation of bubbles was so vigorous that bubbles overflowed to contaminate the area around the container for rinsing. Therefore, they are not suitable for practical use. As shown in fig. 6, in the case of comparative example 4, a single pump is used to circulate the bleaching liquid in the bleaching vessel 121a and the shower liquid through the nozzles 128 via the pipes 123A, 123B, 123C and 123D. Therefore, there is a disadvantage in that thecost is increased due to the increase of the circulation power and the separate arrangement of the spray container 121 c.
In contrast, in the case of examples 1, 2 and 3, the concentration of the iron double salt gradually decreased and was less than 16.5 g/l after the development of 100 rolls of film. Therefore, the photosensitive material can be developed without worrying about the reduction of the bleaching ability. In addition, contamination rarely occurs around the bleaching vessel. Thus, large-scale equipment is not required, and therefore, they reduce costs.
Next, the developing device having the above-described structure is remarkably effective in a developing device having a container for bleaching. In addition, it is also advantageous when it is used as a fixing container.
All the above examples were carried out under the same conditions with the same amount of rinsing liquid: measured at 3.9 liters. In the example of fig. 3, the effect of accelerating oxidation is 5-10% higher than that of examples 1, 2 and 3. In the example of FIG. 4, the effect of accelerating oxidation is 10-20% higher than that of examples 1, 2 or 3. The cross section of the oxidation acceleration part for liquid medicine reduction is 40 mm (width) by 15 mm (depth). The length of the oxidation acceleration part was 60 mm. By addressing the shape or arrangement of the protrusions, the length can be shortened. Preferably, the depth of the flow of the liquid medicine in the oxidation acceleration part is between 5 mm and 50 mm. If it is less than 5 mm, it is difficult to stably circulate the liquid medicine. If the diameter is larger than 50 mm, the effect of accelerating oxidation of the liquid medicine is not good.
By applying the photosensitive material developing apparatus having the oxidation acceleration member of the present invention, oxidation of the bleaching agent is accelerated and photo processing of the photosensitive material is efficiently and stably performed. In addition, the disadvantage of the prior art aeration-accelerated oxidation of air pump type or spray type is that the bleaching liquor accompanies the air bubbles into the adjacent container or the problem of a large reduction in rinsing quality due to the bleaching liquor having degraded can be minimized. The invention effectively realizes the photo development of the photosensitive material. The processing of the photographs can be accomplished by using a small size and relatively economical device without complicating and enlarging the device.
