Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an automatic developing machine for photosensitive materials that can simultaneously process different types of photosensitive materials.

[Prior Art] In a color photo lab, a negative photosensitive material such as a negative color film is developed to create a negative image, this negative image is printed on color paper, and a positive image based on the negative image is printed on the positive photosensitive material of color paper. are doing.

In conventional color photographic processing, three types of equipment must be installed separately: an automatic developing machine for negative photosensitive materials, and an automatic developing machine and automatic printing device for positive photosensitive materials. In general, a certain amount of work space is required around each of these devices, and the space necessary for replenishment adjustment, evaporation correction, tank liquid replacement, and refilling operations must also be secured around these devices. There must be.

Therefore, if the devices are installed separately, it is necessary to ensure that the work spaces around each device do not overlap, which poses a problem when working in a narrow space such as a small color photo lab. For this reason,
Reducing the size of each device has become an important issue.

[Problems to be Solved by the Invention] Under these circumstances, a processor has been developed in which an automatic processor for color paper and an automatic printing device are combined and integrated. However, since negative and positive light-sensitive materials are processed using separate processing solutions, the automatic developing machine for negative light-sensitive materials and the automatic developing machine for positive light-sensitive materials are not integrated.

In other words, there has been an attempt to develop two different photosensitive materials, negative color film and color paper, with one processing solution,
32734, Special Publication No. 52-35298 and Special Publication No. 53-2779
The idea of standardizing processing solutions, especially developing solutions, is described in the specification of the patent.

Furthermore, Japanese Patent Laid-Open No. 58-95342 discloses that liquids from two automatic developing machines are circulated to process different photosensitive materials, such as negative color film and color paper, with a developer having the same composition. . However, these light-sensitive materials for photography and light-sensitive materials for printing originally consist of completely different silver halide compositions, and the original photographic performance cannot be obtained if they are processed with the same developer.

In addition, in order to process negative and positive photosensitive materials using separate automatic processors, the processing solution must always be set at a constant temperature in order to process quickly without waiting time, even though the throughput is small. , flush water must be running.

Therefore, there is a desire for an automatic processor that can simultaneously develop different types of photosensitive materials, requires less installation space, and saves energy and washing water.

This invention was made against the background of the above circumstances, and it is possible to make the automatic processor compact by sharing the processing tank, save the installation area, easily secure the work space around the automatic processor, and moreover, It is an object of the present invention to provide an automatic developing machine for photosensitive materials in which the material conveyance means, processing liquid circulation pump, and temperature control means are standardized, and the cost and washing water required for driving, temperature control, and circulation can be saved. The purpose is

[Means for Solving the Problems] In order to solve the above-mentioned problems, the automatic developing machine for photosensitive materials of the present invention is provided with a dedicated processing tank for processing different kinds of photosensitive materials according to each type, in the developing machine body; A common processing tank for commonly processing different types of photosensitive materials is provided, and at least one of the common processing tanks is a washing tank.

Further, a dedicated processing tank for processing the different types of photosensitive materials is a developer tank.

[Operation] In the present invention, different types of photosensitive materials are processed in dedicated processing tanks, and these different types of photosensitive materials are commonly processed in a common processing tank. At least one of the common processing tanks is a washing tank, and the photosensitive material is washed in this washing tank.

The different kinds of photosensitive materials are developed in respective developer tanks.

[Example] Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a sectional view of the automatic developing machine, FIG. 2 is a plan view, FIG. 3 is a plan view of a processing liquid tank, and FIG. 4 is a plan view showing the installed state of the automatic developing machine.

In FIG. 1, reference numeral 1 indicates a developing machine main body, and the front side of this developing machine main body 1 is provided with a supply section 4 for supplying a negative photosensitive material 2 of undeveloped negative color film or a positive photosensitive material 3 of color paper, and A take-out section 5 from which the processed negative photosensitive material 2 or positive photosensitive material 3 is taken out is provided on each side.

Between the supply section 4 and the take-out section 5, that is, inside the developing machine main body 1, a developer tank 6, a bleach solution tank 7,
A fixer tank 8, a first washing tank 9, a second washing tank 10, and a drying section 11 are provided.

A large number of guide rollers 12 are provided in each of the developer tank 6, the bleach tank 7, the fixer tank 8, the first washing tank 9, the second washing tank 10, and the drying section 11. Endless belts 13 and 14, which are transport carriers, are wrapped around the guide roller 12, and are driven simultaneously or separately by a drive motor 15 provided on the supply section 4 side.

A holding section 16 is provided in the supply section 4, and an undeveloped negative photosensitive material 2 or positive photosensitive material 3 is set in this holding section 16. The ends of the negative photosensitive material 2 or the positive photosensitive material 3 are supported by the endless belts 13 and 14 via clips (not shown), and are conveyed by the endless belts 13 and 14.

The developer tank 6, the bleach tank 7, the fixer tank 8, the first washing tank 9, and the second washing tank 10 are constructed as shown in FIG.
A and a positive developer tank 6b constitute a dedicated processing tank. The negative developer tank 6a and the positive developer tank 6b are each filled with a dedicated developer. The negative photosensitive material 2 is processed separately in a negative developer bath 6a, and the positive photosensitive material 3 is processed separately in a positive developer bath 6b, so that photographic performance can be maximized.

Processing tanks after this developer tank 6, that is, a bleach tank 7, a fixer tank 8, a first washing tank 9, and a second washing tank 9,
The washing tanks 10 each consist of a single tank and constitute a common processing tank, and a washing tank is used as the common processing tank. The negative photosensitive material 2 or the positive photosensitive material 3 processed in the developer tank 6 is transferred to the common bleaching solution tank 7, fixing solution tank 8, first washing tank 9, and second washing tank 1.
Processed as 0.

Even if the automatic developing machine A configured in this way has a working space 17 around it as shown in FIG. Material 2 or positive photosensitive material 3
Since two automatic developing machines B and C are not required, the installation area 19 can be significantly reduced.

Next, the operation of this embodiment will be explained.

When developing the undeveloped negative photosensitive material 2, the magazine 20 containing the negative photosensitive material 2 is set in the holder 16, and the negative photosensitive material 2 is attached to the endless belt 13 with a clip (not shown) at its leading end. Supported and transported. Then, it is processed in a negative developer tank 6a, and then a common bleach solution tank 7,
The toner is transported to a fixer tank 8, a first washing tank 9, a second washing tank 10, and a drying section 11, where it is subjected to development processing.
The processed negative photosensitive material 2 is separated from the endless belt 13 at a take-out section 5 and wound onto a take-up reel 21.

On the other hand, when developing the undeveloped positive photosensitive material 3, a magazine containing the positive photosensitive material 3 is set in the holding section 16. This positive photosensitive material 3 is attached to the other endless belt 1 in the same way as the negative photosensitive material 2.
4 and transported, processed in a positive developer tank 6b, and processed in the same manner as described above.

The conveyance mechanism for the photosensitive material is carried out by using the same endless belts 13 and 14 for the negative photosensitive material 2 and the positive photosensitive material 3, respectively, but any commonly used conveyance mechanism may be used. For example, a friction drive system using fixed rollers, a soda transport system, a chain transport system, etc. are used. Furthermore, the negative photosensitive material 2 and the positive photosensitive material 3 may be transported in the processing tank by separate transport mechanisms. For example, it is desirable that the negative photosensitive material 2 be conveyed by a shot leader system, and the positive photosensitive material 3 be conveyed by the above-mentioned endless belt conveyance system.

However, in the case of endless belts,
Processing liquid is brought into the post-processing tank from the pre-processing tank, so if carrying in the processing liquid has an adverse effect on performance, it is best to use a method in which the tip of the photosensitive material is secured with a guide clip and transported using a licker or chain. This is the preferred method. Further, in such a case, the shot leader method is also one of the desirable conveyance methods.

Furthermore, when the negative photosensitive material 2 and the positive photosensitive material 3 are processed in a common processing tank, liquid circulation in the common processing tank can be performed using a single pump, and the liquid is introduced from a different part of the common processing tank to the pump. Further, the liquid may be sent to any part. For supplying the processing liquid to this common processing tank, it is desirable to produce a stirring effect by directly spraying the processing liquid onto the surface of the processing liquid. As mentioned above, the circulation pump is necessary for stirring and temperature control, but the circulation amount may be the minimum amount necessary for these purposes. Conventionally, the automatic developing machines for the negative photosensitive material 2 and the positive photosensitive material 3 each require a single circulation pump, but now only one common circulation pump is needed.

Furthermore, since the washing tank is also a common treatment tank, significant water savings can be achieved. That is, the amount of rinsing water is specified because the storage stability of the image is guaranteed by flowing a certain amount of rinsing water per unit area of the photosensitive material. however,
It is impossible to run water only while processing photosensitive materials; normally, even if processing of photosensitive materials is stopped, the washing water should be run when the next processing is scheduled. Since there is a lot of water in the tank, reducing the number of washing tanks to one allows for significant water savings.

Furthermore, in those equipped with multiple washing tanks,
A cascade piping is installed, and the overflow of the flush water replenished in the latter stage is fed into the front stage flush tank. This makes it possible to use more of the overflow washing water, and the rinsing effect can improve the washing efficiency.

5 to 7 are plan views of processing tanks showing other embodiments. Figure 5 shows that the common processing liquid is in the washing tank 5.
0 and a stabilizing liquid tank 51. This is carried out when both or one of the negative developer tank 6a and the positive developer tank 6b is used for one-liquid development and fixing, or one-liquid development and bleach-fixing. It will be done. Further, the stabilizing tank 51 may not be necessary in some cases.

In addition, FIG. 6 shows that the common processing tank is the same bleach-fix tank 60 as the bleach tank 70 and fixer tank 8 of the above embodiment, and the first and second washing tanks 61, 62 are connected to the same bleach-fix tank 60.
It has been established.

After the development process is carried out in the negative developer tank 6a or the positive developer tank 6, one bleach-fix tank 60 is used.
This further saves on processing liquid circulation pumps and temperature controllers.

FIG. 7 shows a bleach-fix solution tank 70 located downstream of the negative developer tank 6a during the development process of the negative photosensitive material 2.
will be established. In the development process of the positive photosensitive material, an amplification liquid tank 7 is provided after the positive developer tank 6b.
1 is provided, and amplification processing is performed using peroxide such as hydrogen peroxide. A washing tank 72 and a stabilizing liquid tank 73 are provided as common processing tanks. This is because the amount of silver coated on the positive photosensitive material is small, so the bleaching process and bleach-fixing process are omitted. Further, the negative light-sensitive material and the positive light-sensitive material may be amplified separately, and in this case, it is possible to use a common amplification bath and perform bleach-fixing processing.

Note that although a drying section is provided in each of the above embodiments, it may not be provided in some cases.

[Effects of the Invention] As described above, in this invention, the developing machine main body includes:
It is equipped with a processing tank that processes different types of photosensitive materials, and a common processing tank that commonly processes these different types of photosensitive materials, and this common processing tank has a washing tank. The processing tank can be shared, the automatic developing machine becomes more compact, and it is easy to secure work space around the automatic developing machine.

Moreover, by standardizing the processing tank, it is possible to use a common means of conveying different types of photosensitive materials, and the number of circulation pumps and heaters is also reduced, which is required for temperature adjustment and circulation of the processing solution. Costs are saved. Furthermore, at least one of the common treatment tanks
The tank is a washing tank, and by sharing it, even if washing is performed, the amount of washing water can be greatly saved.

Further, different types of photosensitive materials are developed in respective developer tanks, and good development processing is possible.
