Abstract

PURPOSE:To improve the operability and stabilize the image quality by processing automatically a film which is already subjected to the print processing. CONSTITUTION:The device is constituted with an insertion hole 12 of an object to be developed which is already subjected to photographic print processing, a carrying path 7, a developing part 8 having a developer shower, a water washing part 9 having a water shower, a fixing part 10 having a fixer shower, a water washing and brushing part 12 which rubs said object with a brush while washing it with a water shower, a drying part 21, and a resupply hole 11 which supplies said object brushed in the water washing and brushing part 12 to the brushing part 12 again as required. If a photographic fog is not eliminated in one water washing and brushing, the film can be supplied from the resupply hole 11 to the water washing and brushing part 12 again. Since the development processing is performed automatically in this device, the operability is improved and the image quality is stabilized.

Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a photopolymer (styrene film) used for example as a photo-containing card, a photopolymer (styrene The present invention relates to an automatic developing device that performs a post-baking development process on materials coated with maleic acid resin, Aloex, Carpin Black, etc.).

[Technical background of the invention and its problems]

As described in detail in Japanese Patent Application Laid-Open No. 49-107227, or ) I-105136, an image forming method generally referred to as a photopoly film (or sheet) containing a photopolymer layer Compared to previously known image forming bodies, the body has a simpler structure and can produce clearer images, and it also has excellent resistance to various volatilizations, so there is a movement in the near future to apply this technology to cards, etc. It has become noticeable at times.

However, when an image is printed on such a photopoly film and then developed and fixed to form an image, "fogging" of the emulsion occurs over the whole after the development process due to its structure.
There is a defect that remains, and if left untreated, the image will become smudged, causing a major quality problem. Therefore, after the fixing process, the "fog" is removed with absorbent cotton or the like.

Conventionally, all the troublesome image forming steps as described above are performed manually, which is time consuming and causes problems if the quality is not stable.

[Purpose of the invention]

The present invention has been made based on the above circumstances, and an object thereof is to provide an automatic developing device that can improve workability and stabilize image quality.

[Summary of the invention]

In order to achieve the above-mentioned object, the present invention provides an insertion port into which a printed object to be developed is inserted, and a conveyance path for transporting the object to be developed inserted into the insertion port.

A developing section that is placed on the way of this conveyance path and develops the inserted object to be developed with a developer shower, and a water washing section that is also placed on the way of the conveyance and washes the developed object with water using a water shower. and a fixing section, which is also placed in the middle of the conveyance, and fixes the washed developing object with a shower of fixing solution; It is characterized by comprising a water-washing brushing section for rubbing, a drying section, and a re-supply port for supplying the object to be developed, which has been washed and plunged by the water-washing brushing section, to the water-washing brushing section again as necessary. It is something to do.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 in FIG. 1 is the main body of an automatic developing device, and one side of this main body 1 has an insertion opening 2 for inserting the object to be developed, such as a photopoly film.
and an insertion guide 3, and a discharge port 4 is provided on the other side. In addition, within the main body 1, a conveyance path consisting of a belt conveyor 5 and roller pairs 6 for conveying the photopoly film inserted from the insertion opening 2 substantially horizontally toward the discharge opening 41 is provided. 7 is provided, and along this conveyance path 7, sequentially from the insertion port 2 side,
Developing section 8. A washing section 9, a fixing section 10, a re-supply port 11, and a washing brushing section 12 are arranged with partition walls 13 interposed therebetween. A developer jet nozzle 14 is installed in the developing section 8, and a water jet nozzle 15 of 'fS1 is installed in the washing section 9.
15, but the fixing unit 10 has a fixer fluid injection nozzle 16.16
However, second water injection nozzles 17 are respectively provided in the washing and brushing section 12, and these are configured to inject tea liquid from above the conveyance path 7. In addition, the water washing brushing section 12 is provided with a third water jet nozzle 18 below the conveyance path 7, and a rotary brush 19, 19 with a variable rotation speed above the conveyance path 7. In addition,
20... is a liquid collection plate provided in an inclined state to collect the tea liquid independently.

Further, on the discharge [''4 side of the main body 1, there are 1 and 11 outlets 4.
A drying section 21 for drying the photopoly film discharged from the drying section 21 and a stacker part 22 for accommodating the photopoly film dried in the drying section 21 are connected in this order.

Next, the operation will be explained based on FIG. When a photopoly film is inserted through the insertion port 2, it is transported along the transport path 7 toward the discharge port 4. During this transportation, the photopoly film is first developed in the developing section 8 by being showered with an alkaline developer (for example, 19% Na2C O, solution).Here, the developer is circulated and used. The developed photopoly film still has emulsion remaining in the non-image areas and is in a black state, so it is subjected to water and water in the washing section 9. , the emulsion in the non-image area and the alkaline development M5 are removed, but a "fog" of the emulsion remains throughout.

Next, this water-washed photopolymer film is placed in the fixing section i.

The image is fixed by a shower of acid fixation.

Furthermore, the "fog" of the emulsion remaining in the non-image areas on the film is also fixed. Note that the fixer is used in circulation. Next, the fixed film is subjected to a water shower in the washing and brushing section 12, and the surface of the film is rubbed by the rotating brushes 19 and 19 to remove the "fogging". At this time, the film is also showered with water from below to remove dirt from the bottom surface. Next, this washed and brushed film is dried in a drying section 21 for 4 hours.
After being forcibly dried at a temperature of 0° C. to 50° C., it is stored in the stacker part 22. In addition, if the "fogging" is not removed by - times of washing and brushing, refill the film with the re-supply port 1.
The water is supplied to the water washing and brushing section 12 again from 1.

According to the above configuration, since development processing can be performed automatically, workability can be improved and image quality can be stabilized.

〔Effect of the invention〕

As explained above, according to the present invention, there is provided an insertion port into which a printed object to be developed is inserted, and a conveyance path for transporting the object to be developed inserted into the insertion port.

A developing section that is placed in the middle of this conveyance path and develops the inserted object to be developed with a developer shower, and a water washing section that is also placed in the middle of the conveyance and washes the developed object with water using a water shower. , a fixing section, which is also placed on the way of conveyance, and which fixes the washed developing object with a shower of fixing solution; Workability is improved because it is equipped with a water-washing brushing section that rubs with water, a drying section, and a re-supply port that supplies the object to be developed that has been washed and brushed by the water-washing brushing section to the water-washing brushing section again as needed. This has excellent effects such as improving image quality and stabilizing image quality.
