DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically developing a photographic material.

[0002]

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

In the above-mentioned automatic developing 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 are communicated with each other at the upper part. , Each tank 1,
The lower portions 2 are communicated with each other via a circulation path 3, and the 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.

In an automatic development processor, the amount of the processing solution in each processing tank 1 decreases along with the processing of the photographic light-sensitive material. Therefore, the processing solution is replenished as the processing solution amount decreases.

[0005] To replenish the processing liquid, a method of pumping up the replenishing liquid in the replenishing tank into the sub-tank 2, a method of dropping and supplying the solid processing agent from the solid processing agent supply device 8 into the sub-tank 2, and a method of replenishing the sub-tank 2 And water replenishment methods.

[0006] The size of the sub-tank 2 varies depending on the specifications of the processing liquid replenishment. When replenishing the processing liquid using a solid processing agent, a passage for dropping the solid processing agent into the processing liquid must be secured. Therefore, it is necessary to use a sub-tank having a larger capacity than replenishment of the processing solution for pumping up the replenishing solution.

[0007]

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

Therefore, the above problem can be solved by preparing only a sub-tank having a large capacity capable of coping with the replenishment of the solid processing agent and making the sub-tank correspond to the replenishment specification of the replenisher. In this case, since the capacity of the sub tank is larger than necessary, the amount of the processing liquid also increases.

[0009] Here, the treatment liquid is discarded when it becomes old. However, when the treatment liquid is discharged into the sewage together with domestic water, a pollution problem arises. Therefore, it is necessary to collect this, detoxify it, and dispose it.

For this reason, in an automatic developing apparatus having a large amount of processing solution, there is a disadvantage that the processing of the processing solution is troublesome.

It is an object of the present invention to provide an automatic developing apparatus capable of coping with two types of processing liquid replenishment specifications by using one type of sub-tank.

[0012]

In order to solve the above-mentioned problems, according to the present invention, a plurality of processing tanks are arranged in one direction, and a sub-tank is provided on one side of each processing tank. In the automatic processing apparatus for photographic photosensitive material, which sequentially transports the photographic photosensitive material into the processing liquid in each processing tank in a state where the processing liquid is circulated between the processing tanks, the filling is detachably mounted inside the sub-tank. Adopts an attached configuration.

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

[0014]

With the above construction, by inserting the filling into the inside of the sub-tank, the sub-tank can be adapted to the replenishment of the processing liquid by pumping up the replenishing liquid, and the capacity of the sub-tank is reduced by the filling. However, it is possible to prevent the amount of the processing liquid from increasing.

Further, by removing the padding, the capacity of the sub tank is increased, and it is possible to cope with the replenishment specification of 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 liquids such as a developer and a bleaching liquid are arranged in one direction. By transporting the materials in order, the photosensitive material is developed. Reference numeral 10 denotes a rack for guiding the transfer of the photosensitive material, and the photosensitive material is transported in one direction by a transport 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 a corresponding processing tank 2 at an upper portion thereof. The lower portion of the processing tank 1 and the sub-tank 2 communicate with each other via a circulation path 3, and a circulation pump 4 is incorporated in the circulation path 3. 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 filling 6 is detachably mounted inside the sub tank 2. As the filling 6, for example, one having a closed structure made of 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 an upper opening of the sub tank 2.

The automatic developing apparatus shown in the embodiment has the above-mentioned structure, and the automatic developing apparatus is provided with a processing liquid replenishing specification for supplying a solid processing agent into the sub tank 2 from the solid processing agent supply device 8 shown in FIG. In the case of the sub-tank 2, 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 developing apparatus is of a processing liquid replenishing type in which the replenishing liquid 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 the insertion of the padding 6, an increase in the amount of the processing liquid can be prevented.

Here, in the automatic development processor, 1
Capacity of one processing tank 1 is increased.
In some cases, a plurality of racks 10 are hung in the rack, and the photographic material is conveyed in each rack 10. In this case, as shown in FIG. 3, the sub-tank 2 having a large capacity is used, and a filter 5 is provided 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 processing apparatus according to the present invention, since the filling is removably stored in the sub-tank, the replenishment specifications of the processing solution by supplying the solid processing agent and the replenishment of the replenishing solution are provided. It can correspond to the replenishment specification of the processing liquid.

For this reason, only one kind of sub-tank needs to be manufactured, so that 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 into the sub-tank. Therefore, the amount of the processing solution can be reduced.
