Abstract

PROBLEM TO BE SOLVED: To provide a processor capable of obtaining multistability, irrespective of a small processing amount, and also capable of simultaneously processing carious kinds of film formats. SOLUTION: A small-capacity processing tank 300A and a processing tank 300B are installed according to formats, and also, stock tanks 400 to 408 for storing processing liquid are installed. Thus, a different format of films is processed by one developing processor. The films inserted into the processing tanks 300A and 300B are processed while replacing the processing liquid. The processing tanks A and B and the stock tanks 400 to 408 are made small in capacity, so that the ratio of the replenished liquid amount to the processing liquid amount (motor liquid) is increased, then, the stability is obtained, irrespective of the small processing amount.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photosensitive material processing apparatus for photosensitive material, and more particularly to a photosensitive material processing apparatus capable of handling a plurality of formats.

[0002]

2. Description of the Related Art In recent processing of color photographic light-sensitive materials,
The leading role is shifting from centralized processing in large-scale laboratories to in-store processing called a minilab, and the processing mode is shifting to distributed small-volume processing. In addition, a photosensitive material processing device of the minilab scale can be installed not only in photo shops but also in various stores, and can be installed in stores of other industries such as bookstores, gas stations, laundry shops, supermarkets, and convenience stores. Will be placed. Of course, such a photosensitive material processing apparatus installed in a store preferably has a small installation area, and furthermore, even with a small amount of processing, it is increasingly necessary to operate stably without maintenance.

[0003] The processing method used in the conventional minilab is a replenishment system in which a replenisher is replenished to each processing tank in accordance with the processing amount of the photosensitive material. Lab). Therefore, it is not an exaggeration to say that the processing system does not consider the small processing amount. When the processing amount is low, various performances are destroyed due to the deterioration of the processing solution.

[0004] The main factors contributing to the deterioration of the processing solution are 1) the processing amount per unit time (processing light sensitive material area) 2) the replenishing amount per unit area of the photosensitive material 3) the processing tank capacity 4) the processing tank capacity Opening ratio (factor for increasing the oxidation rate) 5) Treatment prescription.

The aperture ratio here is expressed by the following equation. Aperture ratio (cm ^-1 ) = liquid surface area (cm ² ) / liquid volume (c
m ³ ) By the way, as for 2), there is not much difference between the centralized lab and the mini lab. Increasing 2) increases the cost and the amount of waste liquid, and is a factor to be reduced as much as possible.

[0006] Regarding 4), a small processing tank such as a minilab is basically shallower than a deep processing tank of a large machine of a large laboratory. There is no advantage over a large photosensitive material processing apparatus.

[0007] If 5) is a general-purpose common technology,
The stability of the processing liquid depends on the relationship between the processing amount 1) and the processing tank capacity 3).

[0008] By the way, the processing volume of the large lab per day,
At least 1,000 color negative films may be used, whereas mini-labs with a small processing amount may be reduced to about one thousandth of large labs.

Of course, the photosensitive material processing apparatus is also downsized, but in the existing minilab system, the tank capacity of 3) is at most about one-hundredth of that of a large lab machine. Therefore, under such usage conditions, the processing solution in the minilab system has a residence time (time lapse time) that is about 10 times longer than that in the large lab, and various problems due to the aging of the solution occur. Become. That is, since the processing amount of the minilab is about one thousandth of the processing amount of the large lab, the supply amount of the replenisher according to the unit processing amount of the photosensitive material is almost the same. If the processing amount of the processing solution is small, the rate of replacement of the processing solution in the processing tank when the replenishing solution is supplied (in other words, the rate at which the deteriorated processing solution replaces the replenishing solution) decreases, and the There is a problem that the processing liquid is rapidly deteriorated.

In order to solve such a problem, a system for processing a photosensitive material for improving the stability of a liquid is disclosed in Japanese Patent Publication No. 7-1.
09503, 7-74895, JP-A-2-12525
5. As described in the specification of JP-A-2-199452, a technique has been proposed in which the processing tank is designed in a slit shape to reduce the tank capacity. According to this method, the capacity of the tank is reduced, but it is limited to at most a fraction, and the aperture ratio of 4) is increased (deteriorated).
(I.e., the volume is small, but the required portion of the opening such as the passage of the photosensitive material is not small (there is a limit)). As a result, a satisfactory improvement in liquid stability cannot be obtained. Is the reality.

On the other hand, Japanese Patent Application Laid-Open Nos. 4-123047 and 6-121437 disclose a processing system for solving the stability over time of the liquid.
A single-use type processing system using a small processing container has been proposed, as described in JP-A No. 7-56281. In such a processing method, a new processing chemical is supplied every time the photosensitive material is processed, so that the concept of the stability over time of the processing solution is not necessary. Only this point is a system suitable for a small processing amount. is there. However, when a new solution is supplied and discarded for each treatment, the amount of solution used will increase compared to the conventional replenishment method, even though it is a small processing container. This is not a desirable processing method in terms of cost and environment.

By the way, such a processor can be set to a system capable of fully automatic processing by setting a film. In other words, it provides a simpler processing work in which the film used in the current general-purpose minilab is attached to the leader tab, and each processing bath is transported, and the work of removing the film after processing is not required. It is possible to

However, in the case of automatically processing various films having different formats in the single processing tank as described above, the processing tank and the handling mechanism of the film become very complicated. Only in film was considered possible.

However, the recent color negative films are the same as the conventional color reversal films in the conventional 110,13.
In addition to the 5,120 size, a new film format called APS has been introduced to the market, and its ratio is increasing. Therefore, in the past, most of the film could be processed even with a processor dedicated to the 135 size, but with the increase of APS film, a processor capable of processing the format is required in the future as the number of APS films increases. come.

In the processing solution having bleaching ability, it is particularly preferable to carry out aeration during the processing, since the photographic performance is kept extremely stable. Any means known in the art can be used for aeration, and air can be blown into a processing solution having bleaching ability, or air can be absorbed using an ejector.

Although the aeration may be carried out directly in the processing tank, the photosensitive material processing apparatus of the present invention has a small tank capacity, so that it is preferable to carry out the aeration in the stock tank.

In blowing air, it is preferable to discharge air into the liquid through an air diffuser having fine pores. Such a diffuser is widely used for an aeration tank in activated sludge treatment. Regarding aeration, Z-121 issued by Eastman Kodak Company,
USING PROCESS C-41 3rd Edition (1982
Year), and the items described on pages BL-1 and BL-2 can be used. In the processing using the processing solution having the bleaching ability of the present invention, it is preferable that stirring is strengthened, and the processing is carried out as described in JP-A-3-33847, page 8, upper right column, line 6 to lower left. The contents described in the column and the second line can be used as they are.

In the photosensitive material processing apparatus of the present invention, when performing aeration, it is preferable to use a circulation system, a stock tank, or the like.

The photographic material generally undergoes a washing and / or stabilizing step after desilvering. In the washing and / or stabilizing step, it is necessary to adjust the concentration of the residual thiosulfuric acid of the processed photographic material to 30 to 1500 micromol / m ² .

Specifically, it is desirable that the concentration of the thiosulfate in the final bath is adjusted to be about 0.001 to 0.04 mol / liter. That is, the above-mentioned concentration may be added to the final bath, or when a thiosulfate is used as a fixing component, the amount of replenishment in the subsequent washing and stabilization steps is reduced, and the final bath has the above-mentioned concentration. It is also a desirable embodiment to prepare such a solution.

The specific amount of replenishment varies depending on the concentration of thiosulfate in the fixing step, the number of baths in the washing step and the stabilizing step, etc.
Generally, the amount is about 100 to 1000 ml, preferably about 130 to 700 ml, per m ^{2 of} the photosensitive material.

In the washing water amount in the washing step,
The relationship between the number of washing tanks and the amount of water in the multi-stage
urnal of the Society of Motion Picture and Televis
ionEngineers Vol. 64, pp. 248-253 (May 1955)
Can be obtained by the method described in (1). According to the multi-stage countercurrent method described in the above-mentioned document, the amount of washing water can be greatly reduced.However, due to an increase in the residence time of water in the tank, bacteria are propagated, and the generated suspended matter adheres to the photosensitive material. Problem arises.
