Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This invention provides a replenishment JI! system that supplies replenishment liquid to a plurality of processing liquid tanks. The present invention relates to a processing device having a structure.

(Background of the Invention) As a processing apparatus for this yuzu, for example, there is an automatic developing apparatus that supplies a photosensitive material such as an exposed film into the inside of the apparatus base and processes the photosensitive material with a processing liquid while conveying the photosensitive material.

The processing solution for developing and fixing in this automatic developing device becomes fatigued due to processing of the photosensitive material or due to air oxidation, so a replenisher is supplied to keep the quality of the photosensitive material constant. It has become.

By the way, 11. For example, the amount of replenishment liquid for developing solution and constant sti is large, so the capacity and shape of the liquid replenishment container and liquid collection container can be changed to suit each appetizer, and the capacity and flow meter of the replenishment pump can also be changed. I'm using something like this.

(Problem to be solved by the invention) In this way, the liquid replenishment container and liquid recovery container of the replenisher, as well as the replenishment pump and flow meter, etc.
Since it is manufactured to match the 1IL wear, costs are high and parts management is complicated. Furthermore, since supplementary light aW differs depending on the processing liquid, the frequency of dissolution differs, and liquid management becomes complicated.

Therefore, especially in small automatic developing devices used when the amount of photosensitive material processed per hour is relatively small,
There is a need for a low-cost replenishment method that is easy to manage parts and liquids while maintaining a constant image quality when photosensitive materials deteriorate.

This invention was made in view of such circumstances, and supplementary 3
A series of parts for one part can be delivered at low cost.
Moreover, it is an object of the present invention to provide a processing device that facilitates component and liquid management.

(Means for Solving the Problems) In order to solve the problems of writing, the present invention provides a photosensitive material f.
In a processing device that sends WR to a plurality of processing fiMs for development processing and supplies replenishment liquid to each of these processing 1pi tanks, approximately the same amount of replenishment liquid is supplied to the plurality of processing liquid tanks. It is characterized by being equipped with a replenishment mechanism.

(Function) In this invention, each processing 1JIi supplied from the replenishment mechanism
The amount of replenishment fluid to the tank is approximately the same. Therefore, it is possible to share the parts that make up the nine replenishment mechanisms,
Cost reduction and management of parts and processing solutions will become easier (Example) Hereinafter, an example in which the present invention is applied to an automatic developing device will be described in detail based on the attached drawings.

The main body cover 1 blocks external light, and
The IS opening part is closed with a lid cover 2.

A main switch 3 and a photosensitive material stand support 4 are provided on the front side 1 of the main body cover 1, and the photosensitive material insertion stand cover 5 attached to the fluorescent material stand holder 4 is opened.
The i5i material is fed along an unillustrated insertion table provided on one side of the photosensitive material stand cover 5, and a photosensitive material holder 6 is attached to the cover 2. Inside the cover 1, as shown in FIG. 3, there are provided an under-processing section 7 and an under-processing section 8 which are laminated in a downstream section where the photosensitive material is developed while being fed m. The 11th part of the toner processing section 7 is attached to the opening F&1a of the main body cover 1, and this lower processing section 7 is connected to the current @liquid tank 9 and the fixing 1pi tank 10.
The current tank 9 is arranged close to the side where the photosensitive material is inserted.

The lower processing section 8 is placed on the stopper section 7b which is integrally formed in the F section of the processing section 7.
It is composed of P111 and a drying section 12. Wash with water *[
Reference numeral 11 is arranged above the fixing solution JljlO, and a drying section 12 is arranged above the developing film 9.

...1 The developer tank 9 and the fixer tank 10 have an input end 10-ra 13.14 and an output roller 15.16. Rollers 17 and 18 and JJ side rollers 19 and 20
A washing rack and a drying rack are installed.

The drive gear for these rollers 13-20 is a drive shaft 21.2.
This drive shaft 21.
The helical gear 23 of 22 meshes with the helical gear 26 of transmission @ 25 driven by an electric motor 24. On the mounting part 27 formed on the lid cover 2, replenishment of developer, fixer, and washing liquid is carried out. Each fii filling container 28 storing liquid is placed. This FI-capture light container 28 has a grip part 28a at the end thereof and a liquid inlet/outlet part 28b at the upper part, each having a four-carved shape and having the same capacity.

As shown in FIG. 4, a mounting portion 30 for a liquid recovery container 29 is provided on the portion ) of the main body cover 1.

This attachment part 30 has a guide part 30a and a holding hole part 30b. The side wall of the holding hole 30b is provided with a flat portion 30c for press-fitting and holding the periphery of the liquid inlet/outlet portion 29b of the liquid recovery container 29, and the wall thereof is provided with a discharge hole 30d for the processing liquid.

This liquid recovery container 29 has the same shape as the liquid supplementary light container 28 described in 11r, and is composed of 8 tubes, and is used for both purposes. When inserted through the guide portion 30a and set in the holding hole portion 30b, the i! is retained.

The liquid replenishment container 28 is communicated with the developer ff9, the fixing FI tank 10, and the washing liquid tank 11 via a hose 30 and an auxiliary light pump 31, respectively. The auxiliary light pumps 31 are of the same capacity.

Next, the operation of this embodiment will be explained.

When the electric motor 24 is driven, its power is transmitted to the drive shafts 21, 22 of the top processing section 7 and the lower processing section 8 via the transmission -25. As a result, the input end roller 13 of the photosensitive material processing section 7 protrudes 7J and the input end roller 15 receives the developer M9.
The fixer liquid is transported by human power of 110 (11110-ra 14 and 10-ra 16).

Further, the constant R liquid mto is transported to the input end roller 17 and output side roller 19 of the washing liquid tank 11 of the upper processing section 8.

This photosensitive material is dried in a drying section 12 and taken out onto a pedestal 6 supported by a lid cover 2.

When processing such light-sensitive materials or using air oxidation, developing solution,
Because the fixer gets tired or the washing liquid burns, the developer liquid WI9, fixer 1filo, and washing liquid are supplied from the liquid replenishment container 28 placed on the lid cover 2 through the hose 30 by driving the respective replenishment pumps 31. [Supplied to 11. Since each of the liquid replenishment containers 28 has the same capacity and stores the same amount of replenishment liquid, and the replenishment pump 31 has the same capacity, replenishment of the replenishment liquid ends at the same time. The amount of replenisher for this developer is slightly larger, and the amount of replenisher for fixer is slightly lower, making the same amount. Since the amount is small, it is possible to sufficiently maintain the image quality of the photosensitive material at a constant level until replenishment is completed.

For example, when replacing the developer, if you pull out the drain pipe that also serves as an overflow that does not overflow from the developer fl tank, the developer will be removed from the drain hole of the mounting part 30 of the main body cover 1, as described in Section 4IA. 30d, the liquid is collected into the liquid collection container 29.

When the liquid recovery container 29 is pulled by one angle with the grip 29a, it comes off from the opening 29b or the holding hole 30b, and is easily pulled out while being guided by the guide 30a. Then, when setting the sequential collection container 29 to the mounting part 30 again,
Similarly, the opening 29b is inserted while being guided by the guide part 30a, and is held in the holding hole part 30b. In this way, the liquid recovery container 29 can be attached to and detached from the attachment part 30 with a single touch, and the liquid recovery operation is easy.

And, since the replenishment solution for each processing solution is the same amount,
A common liquid replenishment container 28 and replenishment pump 31 can be used for each, which reduces costs and facilitates management of parts constituting the replenishment mechanism. Furthermore, since replenishment of the processing liquid is completed at the same time, management of the replenishment liquid becomes easier.

Furthermore, since the liquid replenishment container 28 and the liquid recovery container 29 are constructed in the same old manner, they can be used in common.

Note that the processing section for the photosensitive material is not limited to the laminated type as described above, but may be one in which processing 1pi tanks are arranged in an array. It may be constructed with water washing or a stabilizing liquid tank, and the photosensitive material may be a sheet-like film with an exposed image, for example, a roll of film may be processed.
” may be used.

Furthermore, the present invention is applicable not only to such a mechanical developing device, but also to devices equipped with an exposure system, such as an ID cart making device and a device for processing photosensitive materials such as the device jIV described in Japanese Patent Application No. 60-7307. It is also applicable to those using a photosensitive material multilayer method for aging the copied image.

(Effects of the Invention) As described in lif, this invention is equipped with a replenishment JR side that supplies approximately the same amount of replenishment 11Ii leaves to a plurality of processing gIi and tanks. The commonization of parts that make up the system improves efficiency, reduces costs, and reduces the number of parts to eight.In addition, since each replenishment fluid supply ends at the same time, fluid management becomes easier.
