Description

The present invention relates to a photographic developing apparatus for developing a continuous printing paper having a film image printed thereon.

[Conventional technology]

A photographic printing paper on which a negative film image has been printed by a printing device is developed by a developing device, and then cut into image parts for commercialization.

In the printing process in this printing apparatus, the printing exposure amount on the printing paper is optimized to obtain the best print image. That is, using a notch puncher, punch a semi-circular notch at the side edge of the negative film and at a position corresponding to the image pattern, and according to the average transmission density (LATD) obtained by measuring the image with a printing device. Information of the exposure correction amount with respect to the exposure amount is stored in a paper tape as a storage medium. Furthermore, this paper tape is loaded into the printing device,
The presence of notches is detected by a photoelectric switch while conveying the negative film in synchronization with the paper tape, and when the presence of the notches is detected, the conveyance is stopped and the image pattern corresponding to the detected notches is positioned at the printing position. At the same time, the exposure amount correction information stored in the paper tape is read and printing is performed based on this. Further, the photographic printing paper after printing is subjected to development processing by a developing device, and then the finished state is verified, and further, the finished printing cutter cuts the image into individual images.

On the other hand, the negative film is also cut into several pieces and stored in a negative sheet, and it is checked whether or not it corresponds to the finished photographic paper, and it is packed together with the cut photographic paper in each order (each customer). It has become so.

By the way, when the printed image is defective and the image is reprinted, or when the customer checks the printed image after receiving the photographic paper in a bag and reorders it, the print image and the film are ordered. It is necessary to specify the pattern in correspondence with the image of.

Therefore, it is conceivable to print a pattern number corresponding to the image of the film on the photographic paper to facilitate the correspondence between the print image and the image of the film.

[Problems to be solved by the invention]

In this case, it is conceivable to print the exposure number on the printing paper together with the printing exposure processing in the printing apparatus, but since the printing exposure processing in the printing apparatus is performed in a short time, high-speed printing is required to print on the printing paper. Therefore, printing cannot be easily performed with a printer or the like having a slow printing speed.
Further, even if the printing is completed, there is a drawback that the printing paper is then immersed in the developing solution for the developing process, and the printed characters and symbols disappear or become thin. Furthermore, during printing during printing exposure, that is, when the image is not completely developed, the sensitivity of the printing paper may change due to the pressure during printing, and desensitized fog may occur.

On the other hand, it is also conceivable to print the frame number at the time of cutting the finished printing paper with the finishing printing cutter. However, even in this case, high-speed printing is required as in the case described above, printing cannot be performed easily, and there is a drawback in that it is difficult to make correspondence between the photographic printing paper that is continuously conveyed and the print number to be printed on it. . Furthermore, if the print number is not printed before the finish condition of the print image is verified, the print image on the photographic paper with a poor print condition cannot be associated with the corresponding film image, so you want to reprint it. It is not easy to specify the exposure of the film, and it is not easy to specify the proper exposure conditions for this image exposure. That is, unless the pattern number is printed before the finish state of the printed image is verified, there is no effect in the case of subsequent reprinting or additional printing. Therefore, in order to carry out a quick reprint operation, it is necessary to print the pattern number for the correspondence between the print image to be reprinted and the image of the film before the finished photographic paper is cut and bagged. There is.

In consideration of the above facts, the present invention can easily print the pattern number of the image of the film corresponding to the print image of the photographic paper, whereby the pattern designation for performing the quick reprinting work and the additional printing work can be performed. The purpose is to obtain a photographic developing device that can be easily made.

[Means for solving problems]

A photographic developing device according to the present invention is a photographic developing device comprising a developing section for developing a photographic printing paper on which an image of a film is printed and a drying section for drying the developed photographic printing paper. And a reading device for sequentially reading the exposure number from the storage medium storing the exposure number for identifying the exposure pattern together with the exposure correction information for correcting the exposure amount, and the reading device is arranged on the downstream side of the drying section in the conveyance direction of the printing paper. In order to print the pattern number read by the reading device on the high temperature photographic paper on which the image of the film corresponding to this is printed and the cut mark is attached, the print position is determined based on the cut mark and sequentially printed. And a printing device.

[Action]

In the photographic developing device having the above structure, the reading number is read by the reading device from the storage medium which stores the reading number of the film image corresponding to the print image on the photographic paper. The read pattern is printed on the photographic paper which has the image printed on it by the printer and passed through the drying section. Since the conveying speed of the printing paper, that is, the developing process proceeds at a relatively low speed, the printing device does not need to perform high-speed printing. Further, since the printing is performed after the development and the drying processing, the printed pattern does not disappear or become thin.

〔The invention's effect〕

As described above, the photographic developing device according to the present invention can easily print the pattern number of the image of the film corresponding to the print image of the photographic paper, and the correspondence between the print image of the photographic paper and the image pattern of the film. It has an excellent effect that it is easy to put on, and this makes it easy to specify a pattern for performing a quick re-baking work or a reprint work.
