And a photosensitive material processing apparatus.

2. Description of the Related Art A silver halide color photographic light-sensitive material is processed after exposure by processes such as color development, desilvering, washing, and stabilization. For color development processing, color developing solution, for desilvering processing, bleaching solution, fixing solution, bleach-fixing solution, for washing, tap water, well water, chemically or physically treated water or ion-exchanged water, distilled water, stable processing Are used respectively. On the other hand, black-and-white photographic materials are processed by black-and-white development, fixing, and washing with water instead of color development. The temperature of each processing solution is usually adjusted to 20 to 50 ° C., and color and black-and-white photographic materials are immersed in each of these processing solutions for processing.

In order to commercialize such processing of a photosensitive material, it is necessary to reduce the processing amount as much as possible in order to reduce cost and manual work, reduce pollution load, compact processing equipment, and further enhance commercial value. It is required to obtain stable and excellent processing performance with a liquid. In order to obtain stable processing performance, it is essential that the composition of the processing liquid is always kept within a certain range, and in order to obtain excellent performance, it is uniformly immersed in a sufficient amount of processing liquid. Need to be

Accordingly, in the commercial processing of color photographic light-sensitive materials, an automatic developing machine having a processing tank for storing a large amount of processing liquid is used as in a color developing station. In addition, the replenisher for correcting the fatigue of the processing solution is automatically replenished so that the composition of the stored processing solution always falls within a certain range. Such a continuous replenishment system achieves extremely good results when a large amount of color photographic light-sensitive material is processed daily within a certain range. However, because the system supplies replenishment in proportion to the processing amount of the color photographic light-sensitive material, when the processing amount of the color photographic light-sensitive material is relatively small, the consumption and accumulation of the liquid composition components based on the development processing are reduced. Concentration of the processing solution due to evaporation of water and component changes due to air oxidation and decomposition of the components of the processing solution exceeded, and it was not possible to maintain a processing solution composition within a certain range only by replenishment supply based on the processing area, and therefore stable and excellent Processing performance cannot be obtained.

Recently, there has been a demand for diversifying consumer preferences, a demand for immediate color printing, and a demand for color photographic processing as a side job. There is a rapid shift from centralized processing to distributed small-volume processing by minilabs, and further to small-volume and rapid processing. Especially in the idle processing, the shortcomings of the continuous replenishment system are becoming a serious problem. On the other hand, a similar tendency is observed in the processing of black-and-white photographic light-sensitive materials. In particular, in replenishment processing in small processing machines, and in non-replenishment replenishment processing in small rapid processing machines, the problem of continuous replenishment systems is the same as in color processing. It is becoming.

[0006]

In view of the above demand, the present applicant has proposed a simple photosensitive material processing method as described in Japanese Patent Application No. 2-119254. This method has an advantage that stable processing performance can be obtained even with a small amount of processing solution, and the processing apparatus is downsized.

However, in the above method, since the amount of the processing liquid used is small, the temperature of the processing liquid is liable to fluctuate under the influence of the environmental temperature such as the atmosphere, and it is difficult to adjust the temperature of the processing liquid. Therefore, if the processing is performed for a certain processing time, there is a problem that a certain photographic property cannot be obtained. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problem, and to provide a photosensitive material processing apparatus capable of obtaining constant photographic properties under any environment.

[0008]

The above object of the present invention is attained by the following (1) to (4). (1) A photosensitive material processing apparatus comprising: a liquid temperature detecting unit; an environmental temperature detecting unit; and a control unit that adjusts a processing time based on a relationship between the detected liquid temperature and the environmental temperature.

(2) In a light-sensitive material processing apparatus for supplying a processing solution to a silver halide photographic material having at least one photosensitive silver halide emulsion layer on a support and processing the solution, a liquid temperature detecting means, an environment A photosensitive material processing apparatus comprising: a temperature detecting unit; and a control unit that adjusts a processing time based on a relationship between a detected liquid temperature and an environmental temperature.

(3) A silver halide photographic light-sensitive material having at least one light-sensitive silver halide emulsion layer on a support is superposed with a gap through which a processing solution can pass,
In a photosensitive material processing apparatus for processing by supplying a processing liquid to the gap at the start of processing, a liquid temperature detecting means, an environmental temperature detecting means, and a control for adjusting a processing time based on a relationship between the detected liquid temperature and the environmental temperature. Means for processing a photosensitive material.

(4) A photographic light-sensitive material having at least one silver halide emulsion layer on a support is overlapped with a gap through which a processing solution can pass, and the processing solution is supplied to the gap at the start of processing to process. A photosensitive material processing apparatus, comprising: a liquid temperature detecting means, an environmental temperature detecting means, and a control means for adjusting a processing time and a liquid temperature based on a difference between the detected liquid temperature and the environmental temperature. Material processing equipment.

In the present invention, in order to form a gap through which the processing solution can pass, a protrusion may be provided on the emulsion surface or the support surface of the light-sensitive material, but a spacer having the protrusion may be overlapped with the light-sensitive material. Good. By adjusting the processing time and the processing liquid temperature according to the processing liquid temperature and the environmental temperature detected by the processing liquid temperature detecting means and the environmental temperature detecting means, a certain photographic property can be obtained under any environment. Processing can be performed.

The above-mentioned processing apparatus has the advantage that it can be made compact because it uses a small amount of processing liquid and can be carried anywhere. Therefore, every use environment is conceivable,
The processor may be used in both hot and cold regions. If the processing equipment has been left in the same environment for a long time, the temperature of the processing solution is almost equal to the environmental temperature. Can be. Conversely, when the environmental temperature is low, predetermined photographic properties cannot be obtained unless the photosensitive material is processed for a long time. Therefore, when the environmental temperature is high, the processing time is set to be short, and when the environmental temperature is low, the processing time is set to be long so that the processing is performed so as to perform processing so as to obtain a certain photographic property. Can be.

Further, when the processing apparatus is suddenly moved to an environment different from the environment up to that time, since the environmental temperature and the processing solution temperature are different, the processing time is changed according to only the environmental temperature as described above. However, a certain photographic property may not be obtained. Therefore, by setting the processing time in consideration of the processing liquid temperature, the processing can be performed so as to obtain a certain photographic property. For example, if the processing liquid temperature is low even when the environmental temperature is high, the processing time is set to be longer than the processing time when the environmental temperature is high, and if the processing liquid temperature is high even when the environmental temperature is low, the environmental temperature is low. By setting the processing time to be shorter than the above processing time, processing with constant performance can be performed.
As described above, when the difference between the environmental temperature and the processing liquid temperature is large, it is extremely effective to adjust the processing time to perform the processing.

Furthermore, by adjusting not only the processing time but also the temperature of the processing solution, higher-performance processing can be performed and processing control can be facilitated. That is, by adjusting the processing liquid temperature together with the adjustment of the processing time, it is possible to perform a good processing even if the processing time is set even shorter.

The temperature of the processing solution is preferably adjusted in the actual processing section. However, in the configuration of the present invention in which a small amount of processing liquid is supplied to the processing section at the start of processing, the temperature control in the processing section is Have difficulty. Since the processing section is large enough to accommodate only a small amount of processing liquid, it is difficult to provide a temperature adjusting means such as a heater. Further, even if the temperature adjusting means is provided in the processing unit, since the heat capacity of the processing unit is small, it is impossible to substantially control the temperature unless the processing liquid is filled in the processing unit. Therefore, it is preferable that the temperature of the processing liquid is controlled before or during the supply of the processing liquid to the processing unit without controlling the temperature of the processing liquid in the processing unit. Such processing is extremely effective when the difference between the environmental temperature and the processing liquid temperature is large.

A method for drying a photosensitive material by detecting the environmental temperature and changing the drying air temperature is disclosed in Japanese Patent Application Laid-Open No. 63-236043.
However, this method does not mention the processing time or the processing solution temperature. Methods for calculating and processing an optimum processing time corresponding to the processing liquid temperature are disclosed in JP-A-59-177559 and JP-A-2-34848, but these methods adjust the conveying speed of the photosensitive material. This is intended for an apparatus of a type different from the apparatus to which the present invention is applied, in which the processing liquid in the processing section is replaced.

The above-mentioned processing of the present invention may be carried out successively in all the processing steps of the photographic light-sensitive material, but may be applied to only some of the steps and the other steps may be carried out by a conventional processing method. In the present invention, the gap formed when the photosensitive materials are overlapped,
It can be formed by providing projections periodically or randomly on a portion of the silver halide photosensitive material other than the image surface, preferably on the edge of the photosensitive material. In addition, for example, a non-photosensitive film having a convex portion (eg, a sheet or a long shape), a film having an uneven surface (eg, a sheet or a long shape), and a gap formed by supporting both edges of the photosensitive material A spacer such as a member to be used can be used.

The photosensitive material may be wound in a roll shape and overlapped, or may be overlapped in a plane. In the present invention, the method of superimposing in the form of a roll is particularly preferable in that the development processing (photographic processing) can be performed in a very compact container. The gap between the light-sensitive materials in the present invention may be within a range where the processing solution can be stably supplied, and is preferably in a range of 0.1 mm.
It is from 0.1 to 2 mm, more preferably from 0.05 to 2 mm, particularly preferably from 0.05 to 0.5 mm. The narrower gap is preferable in terms of making the container to be processed compact, etc. However, if it is too narrow, on the contrary, it is not preferable in that a problem such as unevenness during development processing occurs and it becomes difficult to obtain a good image. .

In order to form the gap, there are a first method in which a convex portion is provided on both sides of one side of the photosensitive material, and a second method in which a spacer is arranged between the photosensitive materials. The first method includes a method of embossing both ears (both ends) of the photosensitive material by pressure, heating, and the like, and a method of forming a corrugation. Specifically, knurls used in the Japanese style can be used. The shape of the emboss is triangular pyramid, pyramid such as quadrangular pyramid, cone,
It may be a polygonal pillar such as a triangular pillar or a cylinder. Size is diameter (D)
0.01 to 2 mm, height (H) is 0.01 to 2 m
m, the emboss interval (L) is 40 cos ⁻¹ [(20−
H) / 20] mm (0.0)
1 ≦ H (mm) ≦ 2, and H / 5 ≦ D (mm) ≦ 15H is more preferable.

As a method of forming a corrugation, both ends of the film may be corrugated by heating and pressing. The height of the wave may be the same or twice as high as the height (H) of the emboss. The wave gap may be the same or twice as large as the emboss gap (L). The size may be the same or twice as large as the emboss interval (L).
In the second method, a dummy film having convex portions on both sides (only at both ends) and a photosensitive material are superimposed on each other and spirally wound to form a gap, and a gap is formed along both ends of the photosensitive material. Alternatively, a spacer capable of supplying the processing liquid may be provided. The method of forming the protrusions of the dummy film is the same as the method of forming the protrusions provided on the photosensitive material, and the size of the protrusions may be 2 to 4 times the size of the protrusions of the photosensitive material (provided that the protrusions are formed on both surfaces). There is).

In order to supply the processing liquid between the photographic materials, the processing liquid is supplied, for example, by a pump or the like using a pressurized or reduced pressure or a combination of both. The pressure at this time varies depending on the viscosity of the processing liquid in the gap formed in contact with the photosensitive surface of the photosensitive material, but is usually 0.2 to 20 kg / cm ² , preferably 1 to ²⁰ kg / cm ² .
6 kg / cm ² . In the present invention, it is preferable that at least an equal amount of the processing liquid is replaced by the gap volume before one step of the processing is completed. The gap capacity is the sum of the capacities of gaps formed in contact with the photosensitive surface of the photosensitive material. In the processing of a black-and-white photographic light-sensitive material, one step of processing is a development step, a fixing step, a stop step, a stabilization step, a washing step, and the like. In the processing of a color photographic light-sensitive material, a color development step, a fixing step , Bleaching step, bleach-fixing step, reversing step, stabilizing step, washing step and the like. It is not necessary to replace the processing solution by an equal amount or more in all of these processes, but it is preferable that at least one process including the developing step is replaced by an equal amount or more.

The replacement of the treatment liquid is preferably at least one equivalent, more preferably from 1 to 100 equivalents, and still more preferably from 1 to 10 equivalents. Here, when the replacement is performed by changing the flow of the processing liquid, it is preferable to change the processing liquid two or more times for one processing step, more preferably 3 to 100 times.
Particularly preferably, it is changed 4 to 10 times. Thereby, a more stable and uniform photographic image can be obtained. Here, the gap capacity varies depending on the length of the photosensitive material to be used, in addition to the width of the photosensitive material. For example, in the case of 24 to 36 sheets of photosensitive material having a width of 35 mm, 5 to 30 ml, preferably 7 to 15 m is used.
By setting it to 1, it is possible to perform a good developing process while being compact. The amount of the treatment liquid can be preferably 5 to 50 ml, more preferably 10 to 30 ml.

Further, since the processing apparatus of the present invention is compact, the amount of the processing liquid is small, and therefore, even if it is disposable, there is no particular problem such as contamination. In addition, since it is not necessary to consider a temporal change (deterioration) during the processing of the processing liquid, it becomes easier to design the processing agent. When the processing solution is replaced, the method is not particularly limited. For example, when a long photosensitive material is spirally wound, it is necessary to supply the processing solution in a direction substantially perpendicular to the longitudinal direction. It is preferable from the point of view. Here, the substantially perpendicular direction is preferably within ± 30 °. Even in the case of a sheet-shaped photosensitive material, it is preferable to move the processing liquid in the direction in which the path length of the gap is short from the viewpoint of processing properties (such as suppression of uneven development).

Further, the replacement direction of the processing liquid may be kept constant during one step of the processing, or may be changed with time (for example, the reverse direction). The replacement direction of the processing solution is
It is preferable to change over time from the viewpoint of processing uniformity. By forcibly supplying the processing liquid to the narrow gap by the supply means instead of free fall or the like, unexpectedly good photographic images could be obtained even with a small amount of the processing liquid. By placing the photosensitive material in the flow of the processing liquid, the processing can be performed extremely efficiently. This is presumably because advanced liquid agitation, which could not be obtained by the conventional tank developing method, became possible. According to the present invention, in the processing step, it is possible to supply and flow a small amount of the processing liquid without substantially moving the charged photosensitive material into the processing container, thereby enabling efficient processing. According to the present invention, there is an effect that development processing can be performed with a processing liquid amount at least twice as large as a gap volume in contact with a photosensitive surface of a photosensitive material. Here, not substantially moving means that the photosensitive material inside is not moved within the container by manually shaking the container.

When the above method is carried out by an automated apparatus, it is preferable that the main liquid flow is not created by vibrating the processing container greatly. ADVANTAGE OF THE INVENTION According to this invention, processing can be started using a fresh processing liquid and can be fully used. This means not only efficient use of the processing solution, that is, reduction of the amount of the processing solution, but also stabilization of the processing, and also in addition to the case where the processing solution is the developing solution, to increase the sensitivity of the photosensitive material and reduce the size of the image. It was also found that they also had a remarkably excellent effect. In the photographic emulsion layer of the photographic light-sensitive material used in the present invention, any of silver bromide, silver iodobromide, silver iodochlorobromide, silver chlorobromide and silver chloride may be used.
The average grain size of the silver halide grains in the photographic emulsion (the grain size for spheres or grains similar to spheres, and the ridge length for cubic grains is expressed as the average based on the projected area) The particle size distribution may be narrow or wide. The silver halide grains in the photographic emulsion layer may have a regular crystal form such as cubic or octahedral, or may have an irregular crystal form such as spherical or plate-like. Or a compound having a combination of these crystal forms. It may consist of a mixture of particles of different crystal forms. The silver halide grains may have different phases between the inside and the surface layer or may consist of a uniform phase. Further, the particles may be such that the latent image is mainly formed on the surface, or may be the particles that are mainly formed inside the particle.

The photographic emulsion layer after color development is usually bleached. The bleaching process may be performed simultaneously with the fixing process (bleach-fixing process), or may be performed individually. In order to further speed up the processing, a processing method of performing bleach-fixing after bleaching may be used. Further, processing in two successive bleach-fixing baths, fixing before bleach-fixing, or bleaching after bleach-fixing can be arbitrarily performed according to the purpose.

The silver halide color photographic light-sensitive material used in the present invention generally undergoes a washing and / or stabilizing step after desilvering. The amount of rinsing water in the rinsing step depends on the characteristics of the photosensitive material (for example, the material used such as a coupler), the use, the rinsing water temperature, the number of rinsing tanks (the number of stages), the replenishment method such as countercurrent, forward flow, and other various conditions. Can be set widely. Among them, the relationship between the number of washing tanks and water volume in the multi-stage countercurrent method is described in Journal of the Society of Motion Picture and Television.
Engineers (Journal of the Society of Motion Pic
ture and Television Engineers) Vol. 64, 248-253
Page (May 1955).

According to the multi-stage countercurrent method described in the above-mentioned document,
Although the amount of washing water can be greatly reduced, the increase in the residence time of the water in the tank causes a problem that bacteria proliferate and generated floating substances adhere to the photosensitive material. In the processing of the color light-sensitive material of the present invention, as a solution to such a problem, the method of reducing calcium ions and magnesium ions described in JP-A-62-288,838 can be used very effectively. Also, isothiazolone compounds and thiabendazoles described in JP-A-57-8542, chlorine-based disinfectants such as chlorinated sodium isocyanurate, and benzotriazoles, etc. It is also possible to use bactericides described in "Sterilization, Sterilization and Antifungal Techniques of Microorganisms" edited by the Society of Sanitary Engineers, and "Encyclopedia of Antifungal and Antifungal Agents" edited by the Japan Society of Antifungals and Fungi.

The pH of the washing water in the processing of the light-sensitive material used in the present invention is 4 to 9, preferably 5 to 8. Washing water temperature and washing time can also be variously set depending on the characteristics of the photosensitive material, application, etc., but generally ranges from 15 to 45 ° C for 20 seconds to 10 minutes, preferably from 25 to 40 ° C for 30 seconds to 5 minutes. Selected. Furthermore,
The light-sensitive material used in the present invention can be processed directly with a stabilizing solution instead of the above-mentioned water washing. In such a stabilization treatment, JP-A-57-8,543, JP-A-58-14,834,
All known methods described in JP-A-60-220,345 can be used. Further, after the water washing treatment, a stabilization treatment may be further performed. As an example, a stabilizing bath containing formalin and a surfactant, which is used as a final bath of a color light-sensitive material for photography, can be mentioned. . Various chelating agents and fungicides can also be added to this stabilizing bath.

The silver halide color light-sensitive material used in the present invention may contain a color developing agent for the purpose of simplifying and speeding up the processing. In order to incorporate the color developing agent, it is preferable to use various precursors of a color developing agent. For example, indoaniline compounds described in U.S. Pat.
No. 3,342,599, Schiff base type compounds described in Research Disclosure Nos. 14,850 and 15,159, aldol compounds described in No. 13,924, metal salt complexes described in U.S. Pat.No. 3,719,492, urethane-based compounds described in JP-A-53-135,628 Can be mentioned. The silver halide color light-sensitive material used in the present invention may contain various 1-phenyl-3-pyrazolidones as needed for the purpose of accelerating color development.

An embodiment of the present invention will be described below with reference to the accompanying drawings. However, the present invention is not limited only to this embodiment. FIG. 1 is a perspective view of a portable color film processing apparatus according to a first embodiment of the present invention, and FIG. 2 is a principle view of the processing apparatus. The processing apparatus 10 includes all components in a case 12, which is provided with a handle 14 for easy carrying and an opening / closing door 16, so that the inside can be easily exposed. . Either the case 12 or the door 16 is provided with an environmental temperature detecting means such as a thermistor for detecting the temperature of the outside air.

The processing apparatus 10 includes processing liquid tanks 18, 20, and 22 filled with a color developing solution, a bleach-fixing solution, and washing water as processing liquids, respectively, and a waste liquid tank 24 for storing processing waste liquid after processing. I have. Treatment liquid tank 18, 2
The heaters 0, 22 are provided with heaters 19, 21, 23 for heating the respective processing liquids. Each of the processing liquid tanks 18, 20, and 22 is provided with a liquid temperature detecting means such as a thermistor for detecting the temperature of each of the filled processing liquids. As shown in FIG. 3, the exposed film 26 has conical protrusions 28 along both ends in the longitudinal direction.
As shown in (1), it is wound in a roll shape and accommodated in the capsule 30. Since the film 26 has the protruding portion 28 formed by embossing or the like, an appropriate gap is formed between the emulsion surface and the support surface when the film 26 is wound in a roll shape, and the film 26 is superposed. The capsule 30 has an inlet and an outlet for the processing liquid, and is loaded between piston and cylinder units 32 and 34 as supply and discharge means of the processing liquid so as to communicate with the cylinders 36 and 38. Each processing liquid is sequentially filled in the capsule 30 to perform a color developing process. It should be noted that the processing liquid tanks 18, 20, 22
The flow path up to this is substantially air-tight and liquid-tight.
Each cylinder 36, 38 has a larger volume than the capsule 30.

The capsule 30 preferably has a light-shielding function, so that it can be loaded and processed in a bright room. The pistons 40 and 42 are reciprocally driven by motors 44 and 46 via a crank mechanism.
Reciprocating motion of the pistons 40 and 42 in the capsule 30
The processing liquid moves inside. The new processing liquid is supplied to the piston / cylinder unit 32 below the capsule 30, and the waste liquid after the processing is supplied to the capsule 30.
Is discharged from the piston / cylinder unit 34 located above.

Lower piston / cylinder unit 32
Is connected to each processing liquid tank 18, 20, 22 via three valves 48, 50, 52.
The operation of the control device 56 is controlled so that two or more of the nozzles 50 and 52 do not open at the same time, and the processing liquid is supplied into the cylinder 36 one by one. The upper piston / cylinder unit 34 is connected to the waste liquid tank 24 via a valve 54, so that the waste liquid after the film processing can be stored in the waste liquid tank 24. Said motors 44, 46 and valves 48, 50, 52,
54 is a control device 56 having operation buttons 58 and the like.
The operation is controlled according to the processing procedure.

Next, a film processing method will be described with reference to FIG. Capsule 30 containing film 26
After the is loaded into the apparatus, the processing is started by operating the processing start switch. Before starting the process, each piston 4
0 and 42 are located closest to the capsule. First, only the developer supply valve 48 is opened by the processing start signal,
By driving the lower motor 44, the piston 40 descends,
The developer in the tank 18 is sucked through the valve 48 into the cylinder 36 below. At this time, the suction speed by the piston 40 is controlled so as to have a flow rate at which no negative pressure is generated in the developer flow path in order to prevent the generation of bubbles.

After the piston 40 descends to the lowest position, the valve 48 that has been open is closed. Next, the piston 40 starts to rise, and the developer in the cylinder 36 is filled with the capsule 30.
Supply within. At this time, since air is still in the capsule 30, the waste liquid valve 54 is temporarily opened in order to discharge the air from the capsule 30 to the waste liquid tank 24. Then, when all the air in the capsule 30 is exhausted and the developer reaches the valve 54, the valve 54 is closed. At the same time, the upper piston 42 is raised to suck the developer in the capsule 30 into the upper cylinder 38. In addition, so that the air in the waste liquid tank 24 can be appropriately discharged,
Preferably, the waste liquid tank 24 is provided with an air vent hole or the like.

When the lower piston 40 rises to the highest position, the capsule 30 and a part of the upper cylinder 38 are filled with the developer. And the upper piston 42
Is moved up and down in synchronization with the piston 40 below, so that the developer is reciprocated up and down within the capsule 30. The developer is stirred by such reciprocating movement of the developer. It is preferable to provide a temporary suspension period of the developer between the upward movement and the downward movement when stirring the developer to move up and down in the capsule 30. Since a gap is formed in the film 26 wound in the capsule 30 by the conical projecting portion 28 shown in FIG. 3, the projecting portion 28 is not merely moved continuously in the vertical direction. Behind (the downstream side of the liquid flow), the developer is not exchanged well.
If the liquid flow direction is changed continuously and alternately, the protrusion 28
Behind, the liquid does not substantially move. Therefore,
By stopping the liquid for a while without applying a driving force to the liquid at the time of reversal of the liquid flow, turbulence is generated by the force of the liquid flow behind the protruding portion 28, and the liquid flows around a place where it tends to stay. Can be. Therefore, by providing a temporary suspension period of the liquid at the time of reversal of the liquid flow, the stagnation of the developer behind the protrusion 28 can be prevented, and no streak-like development unevenness occurs behind the protrusion 28.

When the stirring is performed for the set time, the discharge valve 54 is opened, and the processed developer is discharged by the vertical movement of both pistons 40 and 42. At this time, the developer in the capsule 30 is not discharged, but is extruded and discharged by the bleach-fix solution supplied next. Upper and lower cylinders 38, 3
When the developer in the tank 6 is discharged, the bleach-fixer in the tank 30 is supplied similarly to the developer. Waste liquid valve 54
When the lower piston 40 is lowered from the upper end to the lower end in a state in which is closed, the bleach-fixing solution is sucked into the cylinder 36.
Thereafter, by opening the waste liquid valve 54 and then raising the lower piston 40, the developer in the capsule 30 is discharged so as to be pushed out by the bleach-fixing solution, and the capsule 30 is filled with the bleach-fixing solution. When all the developer is discharged, the waste liquid valve 54 is closed.

The film 26 in the capsule 30 is bleach-fixed by the bleach-fixing solution in the same manner as the above-described developing process.
The film 26 in the capsule 30 supplied thereto is subjected to a water washing process. The operations of supplying and discharging the bleach-fixing solution and the washing water are the same as those of the developing solution (however, the processing time varies depending on the processing step), and therefore the description of the operation of each means relating to these processes will be omitted. When processing for a predetermined period of time for development, bleach-fixing, and washing is completed, the capsule 30 is removed from the apparatus 10. Next, the film 26 is taken out from the capsule 30, and the film 26 is dried by a known drying means.

FIG. 4 is a partially cutaway perspective view of a capsule 30 used in the above-described apparatus. The film 26 shown in FIG. 2 is wound in a roll and loaded. A shaft 58 is provided inside the capsule 30, and the exposed film 26
And a film is wound around the film 26, and a gap is formed between the films 26. Frame 6 is attached to shaft 58 so that film 26 does not move.
0 is provided. This capsule 30 can also be built into the camera, also serving as a patrone. Note that, even in the case of a film having no protrusion 28, a long flexible spacer having a protrusion 28 similar to the film 26 shown in FIG. 3 can be superimposed on the film and wound around the shaft 58 together. Further, the capsule 30 shown in FIG. 4 has a configuration in which the long film 26 is wound and accommodated, but the capsule 30 may have a configuration in which a sheet-like film is accommodated in a superimposed manner while forming a gap.

Next, the adjustment of the processing time and the temperature of the processing solution, which are essential parts of the present invention, will be described. FIG. 5 is a block diagram of an apparatus for controlling the above processing apparatus. The operation of the entire processing apparatus is controlled by the CPU 180. CPU
The input unit 180 has an environmental thermometer 182 and a processing liquid thermometer 1
84 are connected, and the value detected by them is C
It is supplied to the PU 180. The output of the CPU 180 is connected to the processing liquid moving means 186 and the heaters 19, 21 and 23, and their operations are controlled based on the supplied temperature information. Further, the CPU 180 has a timer 188,
The memory 190 and the arithmetic circuit 192 are connected, and the operation information is calculated by the timer 188, the memory 190, and the arithmetic circuit 192 based on the temperature information detected by each of the thermometers 182 and 184. The timer 188 is used to measure the time from the start of processing and the like, and to adjust the operation timing of each means. The memory 190 has a reference environmental temperature,
The relationship between the processing time, the processing liquid temperature, and the like is stored as, for example, a look-up table.
The processing time, heating temperature, and the like are calculated from the detected temperature with reference to the information in 0. The memory 190 stores, for example, the relationship between the difference between the liquid temperature and the environmental temperature and the development time as shown in the graph of FIG.

FIG. 6 shows an hourly temperature curve of a developing solution of the following processing solution. Such a temperature curve may be obtained experimentally in advance for each photosensitive material and processing solution to be used, and stored in the memory 190. that time,
The temperature curve may be stored as a table, a curve, or a function approximation. Alternatively, the relationship between the temperature of the processing liquid, the environmental temperature, and the processing time or the processing liquid speed (average flow velocity in one stroke) may be stored as the temperature characteristic.

The control by the above device will be described below. First, when the environmental temperature and the liquid temperature are detected, the CPU 180 calculates these temperature differences and calculates the optimum processing time according to the temperature differences with reference to the information in the memory 190. For example, if the development processing, the developing solution temperature of 30 ° C., the room temperature is at 30 ° C., these temperature differences are 0 ° C., FIG.
From 6 , the development processing time is set to about 400 seconds. Next, the CPU 180 refers to the timer 188 and
The processing liquid moving means 186 such as 8, 50, 52, 54, the motors 44, 46, etc. are operated for a set time while taking timing.
