DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a development processing apparatus used for development processing of a photosensitive film or photographic paper photographed optically or by radiation such as X-ray in medical, industrial and general fields.

[0002]

2. Description of the Related Art In the medical, industrial and general-purpose fields, a photosensitive film which is photographed by radiation such as optical or X-ray and requires an early result is usually processed.
Store the development processing solution (development solution / fixing solution / developing / fixing solution, etc., simply referred to as processing solution) in a predetermined processing container
A photosensitive film (hereinafter simply referred to as a film) is immersed in the film to develop the film, and then the film is transferred in the air and fixed in the next processing container. Also, when the processing amount and the processing frequency are high, A method has been adopted in which a processing solution is stored in a solution tank having a relatively large capacity provided with a transporting means such as a transfer roller, and the film is continuously processed for development processing.

By the way, in general, the processing container or tank for containing the processing liquid is opened to the atmosphere for loading and unloading the film, so that the characteristics of the contained processing liquid are deteriorated by repeated use. At the same time, it deteriorates with time due to oxidation on the liquid surface. Furthermore, the processing liquid attached around the liquid surface of the processing equipment such as the transfer roller is dried and solidified or crystallized to become a factor for damaging the processing film. Therefore, in these conventional development processing methods, in order to continue stable development processing, the characteristic changes of the processing liquid are continuously managed and replenished or replaced in a timely manner, and the liquid level around the processing equipment is frequently changed. It is required to remove the dried solidified substance and the crystallized substance of the processing liquid by cleaning.

However, since management of these processing liquids and equipment is relatively complicated, in reality, the time for replenishment / replacement of processing liquids and equipment cleaning is lost, and valuable images become unclear or damaged. It often causes the problem of In addition, the treatment liquid that has reached the time of replacement must be subjected to neutralization treatment, etc. in accordance with relevant laws and regulations, and then discarded. The larger the amount used, the more costly and troublesome the waste liquid treatment becomes. Stable development can be performed with the processing liquid of
Moreover, there has been a demand for a developing processing apparatus which can eliminate or reduce cleaning of processing equipment and has a compact structure.

The inventors of the present invention have been enthusiastically working on improvement studies to meet the above-mentioned demand.
By submersing the slit-shaped film inlet and outlet, it is possible to prevent deterioration of the processing liquid stored inside due to oxidation, and to prevent drying and solidification and crystallization to prevent film damage (Patent No. 1773397) And 17th
No. 73398) was developed and further investigated, and a treatment container having a flat liquid chamber with slit-shaped film inlets and outlets in the front and back was placed in the water tank, and the treatment liquid was sent into the liquid chamber. By supplying and reciprocally flowing in the lateral direction, the processing solution is brought into uniform contact with the passing film to perform development processing, and stable development processing can be achieved with an extremely small amount of processing solution, and complicated processing solution Proposal of a development processing device that eliminates the need for replenishment / replacement management and equipment cleaning (Japanese Patent Application No. 4-17)
No. 21)

Further, subsequently, by further improving the developing processing apparatus of the above-mentioned prior application, prior to the present application, a processing container having a small volume liquid chamber is arranged in a water tank, and a rotating roller for transferring a film. Under the condition that the rotary roller is limited to the both side surfaces of the rotary roller, the liquid can be sealed in the liquid chamber and the contact speed of the processing liquid with respect to the passing film (agitation (Development speed) can be stably increased, power consumption can be suppressed to a low level, and a development processing device that can achieve stable development processing without unevenness with an extremely small amount of processing liquid continuously and quickly is proposed. Japanese Patent Application No. 5-143678 and Japanese Patent Application No. 619462 based on the priority claim by the Japanese Patent Application No. 5-143678).

Further, each processing container (32) is immersed in the purified water (W) supplied into the water tank (31), and its liquid chamber (32)

[0009]

However, the development processing apparatus of the above-mentioned prior application (Japanese Patent Application Nos. 5-143678 and 6-19462).
In more detail, with respect to a normal-sensitivity X-ray film or a monochrome film, although the above-described excellent effects can be obtained, when a high-sensitivity monochrome film or a color film is developed, Furthermore, it has been found that when an attempt is made to develop a long film having a normal sensitivity at a higher speed, the following problems are caused and remain as problems to be solved.

For example, a screen film (normal sensitivity film using an intensifying screen) generally used for X-ray photography in the medical field requires almost the same time for developing and fixing, so that the developing and fixing time ratio is 1 : 1 can be continuously processed. On the other hand, non-screen films (high-sensitivity films that do not use intensifying screens), which have been generally used in the industrial field, have been used in recent years because the amount of X-ray irradiation can be reduced to reduce the exposure dose. However, these high-sensitivity films require a longer time for fixing than developing due to the high silver content, and the ratio of developing time to fixing time is 1: 1.5 or more. Is. Conventionally, when continuously processing these high-sensitivity films, the time ratio of development and fixing is generally set to 1: 1 in accordance with the fixing time, but in order to shorten the processing time, it is adjusted to the development time. If continuous processing is to be carried out, for example, in the stationary processing solution, it is necessary to increase the transit time in the fixing solution by 1.5 or more than in the developing solution.

Here, in the developing processing apparatus of the prior application, the film is passed through the processing containers of the same length in the same transit time, so that the transfer speed of the high-sensitivity film is increased and the continuous processing is performed in a shorter time. The flow rate of the fixing solution circulated and fed to the liquid chamber of the second processing container is set higher than the flow velocity of the developer circulated and fed to the liquid chamber of the first processing container, or It is necessary to adjust the density to give a difference in the speed of the development reaction and the fixing reaction. Also, for a long film with normal sensitivity, in order to increase the transfer speed and further shorten the total length transit time (Top to End), in the same manner as above, the process of circulating feeding to the liquid chamber of each processing container is performed. It is necessary to further accelerate the development and fixing reactions by adjusting the flow rate and concentration of the liquid. However, as the flow velocity of the treatment liquid is increased, the flow path resistance is remarkably increased, and a large amount of power is required to circulate and feed the treatment liquid, and even if the flow velocity and the concentration of the treatment liquid are increased beyond a certain limit, Since the reaction between the processing solution and the chemicals on the film surface is not necessarily promoted in a proportional manner, there is a certain limit in adjusting the concentration and flow rate of the processing solution, and therefore, in the development processing of the high-sensitivity film, It is necessary to keep the concentration or flow velocity of the developing solution fed to the processing container of 1. Further, even for a long film having a normal sensitivity, the increase of the transfer speed is restricted for the same reason, and as a result, it becomes difficult to further shorten the processing time.

On the other hand, in the development processing of color film, for example, in a series of processing such as color development-stopping-hardening-water washing-bleaching-water washing-fixing-final water washing, water washing itself is incorporated as an essential step between specific treatments. Be done. On the other hand, in the development processing apparatus of the prior application, the film that has passed through the liquid chamber of each processing container is transferred to the liquid chamber of the next processing container through the water in the water tank, that is, in each unit processing. Since it is washed with water each time, there is no problem with a monochrome film, but it is difficult to achieve a stable development process with a color film.

Furthermore, in the development processing apparatus of the prior application,
Since the film to be processed is transferred through the water in the water tank at each unit processing, if the development processing is not carried out in a bright room, the film in the water tank will not be exposed until the fixing is completed. It is necessary to completely prevent the light from entering the water in the water tank by completely covering the upper opening with a light-shielding hood or the like, and this is one obstacle to ease of handling and downsizing. This point also remains as an issue to be improved.

The present invention has been made to solve the above-mentioned problems, and has a structure in which a processing apparatus having a plurality of small-volume processing liquid chambers is arranged in a water tank, and easily shields the film to be processed from light. It is possible to secure the time, and it is possible to appropriately set the transit time in each processing solution for each unit processing performed continuously.Therefore, it is necessary to carry out a plurality of processings having different reaction times including a long film of ordinary sensitivity. It is an object of the present invention to provide a developing processing apparatus capable of continuously and rapidly achieving stable developing processing without unevenness with a small amount of processing liquid, even for various films such as high-sensitivity film and color film.
