JP-A-49-107227, or JP-A-50-
As described in detail in Japanese Patent No. 105136, an image forming body generally referred to as a photopoly film (or sheet) containing a photopolymer layer has the following characteristics compared to previously known image forming bodies: Because it has a simple structure, provides clear images, and has excellent resistance to various types, there has recently been a noticeable movement to apply this technology to cards and the like.

However, when an image is printed on such a photopolymer film and then developed and fixed to form an image, due to its structure, the entire emulsion remains "fogged" after the development process, and this is left as is. If left unattended, the image will become smeared, causing a major quality problem, so after the fixing process, the "fog" is removed with absorbent cotton or the like.

Conventionally, all of the troublesome image forming steps described above have been performed manually, which poses problems in that it is time consuming and the quality is unstable.

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 object, the present invention provides an insertion opening into which a printed object to be developed is inserted, a conveyance path for conveying the development object inserted into the insertion opening, and a conveyance path for this conveyance path. a developing section which is disposed on the way and develops the inserted object to be developed by showering a developing solution;

It is arranged through. The developing section 8 has a developer jetting nozzle 14, the first cleaning section 9 has a first water jetting nozzle 15, the fixing section 10 has a fixing fluid jetting nozzle 16, and the second cleaning section 12 has a developer jetting nozzle 14. are respectively provided with second water injection nozzles 17, which are adapted to inject each liquid from above the conveyance path 7. Moreover, in the second cleaning section 12, a third water injection nozzle 18 is provided below the conveyance path 7.
Sponge rollers 19, 19 are provided on the upper part of the rollers, respectively. In addition, 20... is a liquid collection plate provided in an inclined state to collect each of the above-mentioned liquids independently.

Furthermore, an outlet 4 is provided on the outlet 4 side of the main body 1.
A drying section 21 for drying the photopolymer film discharged from the drying section 21 and a stacker section 22 for storing the photopolymer film dried in the drying section 21 are connected in this order.

Incidentally, the drive mechanism for the sponge rollers 19, 19 is constructed as shown in FIGS. 2 and 3. That is, the sponge roller 19,
19 each has a cylindrical sponge 23 fitted onto a shaft 24 and prevented from moving in the axial and circumferential directions by a stopper 25 and a roller presser 26, and the rear end side of the shaft 24 is on the rear side. The front end of the shaft 24 is supported by the frame 27 via a rear bearing 28, and the front end of the shaft 24 is supported by the front frame 29 via a front bearing 30 and a rotating ring 31, respectively. The sponge rollers 19, 19 have spur gears 32, 33 on the shaft 24, a transmission shaft 34, a spiral gear 35,
A driving force from a motor (not shown) is transmitted through a driving force transmitting means such as 36, so that the film is driven at substantially the same circumferential speed as the film conveying speed of the conveying path 7. Further, an endless meandering groove 37 is carved around the shaft 24, and an engagement protrusion 38 that engages with this meandering groove 37 is fixed to the rotating ring 31. ..., the motor 4 via the chain 40..., etc.
1, as shown in FIGS. 4 and 5, it is reciprocated in the axial direction, that is, in the width direction of the conveyance path 7, at a constant cycle.
The sponge rollers 19, 19 are configured to be brought into contact with the surface a of the film on the transport path 7 with constant pressure (pressure that slightly deforms the sponge 23) over the entire surface by adjusting screws 42, 42. has been done.

Next, the operation will be explained based on FIG. When photopolyfilm a is inserted from insertion port 2,
This is transported toward the discharge port 4 by the transport path 7. During this transportation, the photopoly film a is first developed in the developing section 8 by being showered with an alkaline developer (for example, a 1% Na ₂ CO ₃ solution). Here, the developer is used in circulation and the temperature can be adjusted. Next, since the developed photopoly film still has emulsion remaining in the non-image areas and is black and dirty, it is showered with water in the first washing section 9 to remove the emulsion and alkali from the non-image areas. The developer is removed, but a "fog" of emulsion remains throughout. The washed photopolymer film is then showered with an acid fixing solution in a fixing section 10 to fix the image thereon. Also, the "fogging" of the emulsion that remained in the non-image areas on film a
will also be established. Note that the fixer is used in circulation. Next, the fixed film is subjected to a shower of water in the second cleaning section 12, and the film surface is rubbed by sponge rollers 19, 19 to remove the "fog". At this time, the film a is also showered with water from below, and dirt on the lower surface is removed. Next, this washed and rubbed film a is heated to 40°C to 50°C in a drying section 21.
After being forcibly dried at a temperature of , it is stored in the stacker section 22. If the "fogging" is not removed by one-time water washing and rubbing, the film a is again supplied to the second cleaning section 12 and drying section 21 through the re-supply port 11.

According to the above configuration, since development processing can be performed automatically, workability can be improved and image quality can be stabilized. In other words, in manual development, the processing speed is 8~ per hour.
Although it can only process 10 sheets, this device can process approximately 50 sheets per hour. Also,
There is no variation in development from film to film or from worker to worker.

Moreover, in the second cleaning section 12, since the sponge rollers 19, 19 rub the surface A of the film, the fog can be scraped off more uniformly than when, for example, a brush roller or the like is used to rub the film. does not occur.

Further, since the sponge rollers 19, 19 are configured to have the same circumferential speed as the conveyance speed of the conveyance path 7 and to slide the film surface A by reciprocating in the width direction of the conveyance path 7, for example, the circumferential speed of the sponge rollers is Even if the film is extremely thin, the rear end of the film a may be flipped up or bent, or the sponge roller 19 may There is no need to wrap it around.

As explained above, according to the present invention, there is an insertion port into which a baked object to be developed is inserted, a transport path for transporting the development object inserted into the insertion port, and an arrangement located on the way of the transport path. a developing section which develops the inserted object to be developed using a developer shower; a first cleaning section which is also arranged on the way of conveyance and washes the developed object with water shower; A fixing unit is placed on the way and fixes the washed developing object with a shower of fixing solution, and a fixing section is also placed on the way of conveyance, and the fixed developing object is washed with a shower of water and rubbed with a sponge. a second washing section for drying the washed and rubbed object, and a drying section for drying the washed and rubbed object, and supplying the dried object to the second washing section and drying section again as necessary. Since it is equipped with a re-supply port, it is possible to improve workability and stabilize image quality, and moreover, it is possible to uniformly remove fog. In addition, since the sponge roller is rotated at the same speed as the conveyance speed of the object to be developed and is reciprocated in the width direction of the conveyance path to rub against the object to be developed, even if the object to be developed is extremely thin, This has the effect that the rear end portion is not rolled up or rolled up, so that it can be transported well and fog can be removed.
