Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic development processing apparatus for photographic light-sensitive materials.

[0002]

2. Description of the Related Art As shown in FIG. 4, an automatic developing apparatus for developing a photographic light-sensitive material such as a film has processing solutions such as a developing solution, a bleaching solution and a fixing solution in a plurality of processing tanks 1 arranged in one direction. , And the photographic light-sensitive material is sequentially transferred into the processing solution in the processing tank 1 for development processing.

In the above automatic development processing apparatus, a sub-tank 2 is provided on one side of each processing tank 1 in order to make the temperature of the processing liquid uniform, and the sub-tank 2 and the processing tank 1 communicate with each other at the upper part. , Each tank 1,
The lower parts of 2 are communicated with each other through a circulation path 3, and a processing liquid is circulated between the processing tank 1 and the sub tank 2 by driving a circulation pump 4 incorporated in the circulation path 3.

Further, in the automatic development processing apparatus, the amount of the processing liquid in each processing tank 1 decreases with the processing of the photographic light-sensitive material, so that the processing liquid is replenished as the processing liquid amount decreases.

To replenish the treatment liquid, a method of pumping up the replenishment liquid in the replenishment tank into the sub-tank 2 and a method of dropping the solid treatment agent into the sub-tank 2 from the solid treatment agent supply device 8 and the sub-tank 2 thereof There is a method of replenishing water.

The size of the sub-tank 2 varies depending on the specifications of the replenishment of the treatment liquid, and when replenishing the treatment liquid using a solid treatment agent, a passage for dropping the solid treatment agent into the treatment liquid must be secured. Therefore, it is necessary to use a sub-tank having a larger capacity than that of the replenishment of the processing solution for pumping up the replenisher.

[0007]

By the way, in the conventional automatic developing apparatus, several kinds of sub-tanks having different sizes are prepared to meet the specification of replenishment of the processing liquid, which is extremely uneconomical. There was a problem that the cost was high.

Therefore, if only a sub-tank having a large capacity for replenishing the solid processing agent is prepared and the sub-tank conforms to the replenishing solution replenishing specification, the above problems can be solved. In this case, since the sub-tank has an unnecessarily large capacity, the processing liquid also increases.

[0009] Here, the treatment liquid is discarded when it becomes old, but when it is thrown away into the sewage together with the domestic water, a pollution problem occurs. Therefore, it is necessary to recover the treatment liquid, detoxify it, and dispose of it.

Therefore, in an automatic development processing apparatus having a large amount of processing liquid, there is a problem that the processing of the processing liquid is troublesome.

An object of the present invention is to provide an automatic development processing apparatus capable of responding to two kinds of processing liquid replenishment specifications with one type of sub-tank.

[0012]

In order to solve the above problems, in the present invention, a plurality of processing tanks are arranged in one direction, a sub tank is provided on one side of each processing tank, and the sub tank and the processing tank are provided. In the automatic processing device for photographic light-sensitive material, which sequentially conveys the photographic light-sensitive material into the processing liquid in each processing tank in a state where the processing liquid is circulated between the two, the filling material can be detachably attached inside the sub-tank. The installed configuration is used.

Here, the sub-tank is of a size that can meet the replenishment specification of the solid processing agent.

[0014]

According to the above construction, by inserting the filling into the inside of the sub-tank, the sub-tank can meet the specification of replenishing the processing liquid by pumping up the replenishing liquid, and the filling reduces the capacity of the sub-tank. However, it is possible to prevent the processing liquid volume from increasing.

Further, by removing the filling material, the capacity of the sub-tank is increased, and it is possible to meet the specifications for replenishing the processing liquid using the solid processing agent.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIGS. 1 and 2, a plurality of processing tanks 1 containing various processing solutions such as a developing solution and a bleaching solution are arranged in one direction, and the processing solution in the processing solution in the processing tank 1 is exposed. The photographic light-sensitive material is developed by sequentially conveying the material. Reference numeral 10 denotes a rack for guiding the transfer of the photographic light-sensitive material, and the photographic light-sensitive material is conveyed in one direction by a conveying device provided in the rack 10.

A sub-tank 2 is provided on one side of each processing tank 1, and each sub-tank 2 communicates with the corresponding processing tank 2 at the top. Further, the processing tank 1 and the sub tank 2 communicate with each other at their lower parts via a circulation path 3, and a circulation pump 4 is incorporated in the circulation path 3. By driving the circulation pump 4, the processing tank 1 and the sub tank 2 are connected. The processing liquid is circulated between them.

Reference numeral 5 denotes a filter. The processing liquid flowing from the processing tank 1 to the sub tank 2 is filtered by the filter, and the filtered processing liquid flows into the circulation path 3.

A padding 6 is detachably attached inside the sub-tank 2. As the padding 6, for example, a closed structure having a blow molded product can be used. The filling 6 made of the molded product is held in a state of being immersed in the processing liquid by an openable / closable lid 7 that closes the upper opening of the sub tank 2.

The automatic development processing apparatus shown in the embodiment has the above-mentioned structure, and the automatic development processing apparatus supplies the processing solution replenishment specification for supplying the solid processing agent into the sub tank 2 from the solid processing agent supply device 8 shown in FIG. In the case of the above, the filling 6 is removed from the inside of the sub tank 2, and the solid processing agent is supplied to the position where the filling 6 is removed.

If the automatic development processing apparatus is of a processing solution replenishing specification in which the replenishing solution is pumped up to the sub tank 2, the filling 6 is inserted into the sub tank 2. Since the volume of the sub tank 2 is reduced by inserting the padding 6, it is possible to prevent the amount of the processing liquid from increasing.

Here, in the automatic development processing apparatus, 1
Increase the capacity of one processing tank 1
In some cases, a plurality of racks 10 are suspended inside, and the photographic light-sensitive material is transported in each rack 10. In this case, as shown in FIG. 3, the sub tank 2 having a large capacity is used, and the filter 5 is provided so as to face the rack 10 in each processing tank 1. For such a sub tank 2,
The padding 6a for partitioning is inserted between the plurality of filters 5, and the paddings 6b are inserted on both sides of the padding 6a.

[0024]

As described above, in the automatic development processing apparatus according to the present invention, since the filling is detachably accommodated in the sub-tank, the processing liquid replenishment specification by the supply of the solid processing agent and the supply of the replenishment liquid are provided. It is possible to meet the processing liquid replenishment specification.

For this reason, since only one type of sub-tank needs to be manufactured, the cost can be reduced and, in the case of the replenishment specification by supplying the replenisher, the volume of the sub-tank is reduced by the padding inserted in the sub-tank. Therefore, the amount of processing liquid can be reduced.
