Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a frame number printing device for printing a frame number on a photographic paper after development.

2. Description of the Related Art Conventionally, there is known an automatic photographic printing apparatus used to print a positive image recorded on an original image film such as a developed negative film by printing it on photographic paper and developing it. When using this automatic photo printing device, a verification device (hereinafter referred to as “notch puncher”) performs a verification work before printing with the automatic photo printing device, and the automatic photo printing device prints based on the result of this verification work. It is processing.

That is, a notch puncher is used to punch a semicircular notch at the side edge of the original film and at a position corresponding to the image pattern, and the average transmission density (LATD) obtained by photometrically measuring the image with an automatic photoprinting device. The information of the exposure correction amount corresponding to the exposure amount is punched in a paper tape as a storage medium. Then, a paper tape is loaded into the automatic photo printing apparatus, the presence of a notch is detected by a photoelectric switch or the like while conveying the original film in synchronization with the paper tape, and when the presence of the notch is detected, the conveyance is stopped and the detection is performed. The image pattern corresponding to the notch is positioned at the printing position and printing is performed based on the average transmission density and the exposure correction information.

However, if the printing development of some image areas fails (for example, poor exposure, poor color balance, etc.), it is necessary to reprint, but similar image areas are continuously shot on the original film. In the case where there is an image, it is difficult to find a pattern corresponding to the image pattern that has failed to be reprinted, from the image pattern of the original film. In particular, when a large number of original films are processed by connecting a plurality of films with a splice tape, the efficiency of the re-printing work for each order (one case) is extremely poor. Further, when the customer makes a reorder such as reprinting, it is difficult to correspond the print and the image pattern of the original film, and the pattern designation becomes complicated. In order to solve this problem, JP-A-56-128933 and JP-A-5-128933
As described in Japanese Patent Laid-Open No. 6-128932, a printer has been proposed in which an image side identification code is attached to a printed printing paper.

[Problems to be solved by the invention]

However, the prints printed by the printing apparatus that does not have the function of attaching the image-giving identification code cannot be attached with the image-giving identification code, and therefore the efficiency of collation for reprinting and printing is poor. . Further, when an identification code is attached to the printing apparatus, a method generally used is to apply a pressure to undeveloped printing paper, such as a dot impact printer. In this case, it is known that after development, density unevenness called desensitization unevenness occurs in the image on the front side of the portion to which pressure is applied, and various secondary measures must be taken to reduce this. .

According to the present invention, the image pattern identification code can be attached to the photographic paper printed by the printing apparatus which does not have the function of attaching the image pattern identification code to the photographic paper as described above. It is an object of the present invention to obtain a pattern number printing device that can easily check the above-mentioned items and that does not cause uneven desensitization.

[Means for solving problems]

A pattern number printing device according to the present invention is a pattern number printing device for printing a pattern number on a rolled photographic paper after development, and a cut mark detection device for detecting a cut mark attached to the rolled photographic paper. , A pattern number reading means for sequentially reading a pattern number from a storage medium in which the pattern number is stored together with the exposure amount correction information which is read during printing and corrects the exposure amount, and the pattern number read by the pattern number reading means is cut. And a printing unit that sequentially prints on photographic paper in synchronization with the cut marks detected by the mark detection device.

[Action]

According to the present invention, when an image is printed on a roll-shaped photographic printing paper, a cut mark is usually added as a mark for cutting each image in a subsequent process. The pattern number printer has a function of detecting the cut mark.

By the pattern number reading means, pattern numbers stored in advance together with the exposure amount correction information are sequentially read from the storage medium (for example, paper tape). The read pattern number is sequentially printed on the printing paper by the printing means in synchronization with the cut mark detected by the cut mark detecting device. In addition,
It is also possible to print the exposure correction information together with the pattern number.

Therefore, when collating the image of the original film with the image of the photographic paper, it is possible to easily find the desired pattern from the original film by comparing the pattern number printed on the photographic paper with the pattern number of the original film. be able to.

Further, as a unique effect of the present invention, since printing is performed after development unlike the conventional case, desensitization at the time of development due to printing does not occur and the finish of the image is not hindered.

Further, the paper tape 52 is set to the paper tape reading unit 16 with the portion in which the exposure number corresponding to the first exposure of the photographic paper 36 is stored as the head. In this case, since the leading pattern number of the paper tape 52 corresponds to the leading pattern of the photographic printing paper 36, the leading portions of the photographic paper 36 may be set together.

From this set state, in step 60, the photographic paper transporting drive device 35 is operated to transport the photographic paper 36 in the direction of arrow C. At the same time, the drive device 53 is operated and the paper tape 52 is sent to the paper tape reading unit 16. At step 62, it is determined whether the detector 46 has detected the cut mark 44 displayed on the photographic paper 36. If not detected, the process returns to the step 60 and the photographic paper 36 and the paper tape 52 are conveyed. When the detector 46 detects the cut mark, the printing paper 36 and the paper tape 52 are fed at step 64.
Is stopped. Next, at step 66, the paper tape reading section 16 is operated to read the pre-stored pattern number from the paper tape 52. In step 68, the printing section 22 is operated, and the print number read in step 66 is printed on the back surface of the printing paper 36. At step 70, it is judged whether or not the paper tape 52 is supplied to the paper tape reading section 16. Paper tape
When 52 is still supplied, the process returns to the step 60 and the following program is repeatedly executed. If the paper tape 52 is not supplied, the process ends.

In the present embodiment, printing on the back surface of the photographic paper 36 is performed by the photographic paper 36.
However, the printing may be performed in the direction opposite to the conveying direction along the conveying direction of the printing paper 36. In this case, the printing of the photographic printing paper 36 does not have to be temporarily stopped for printing, and printing can be performed while the printing is being carried.

〔The invention's effect〕

As described above, according to the present invention, the pattern number of the original image film can be surely displayed on the photographic printing paper (photograph) on which the corresponding image is printed. At this time, if other information included in the storage medium, for example, exposure amount correction information, is also displayed, it can be effectively used as reference information when reprinting. In addition, the print number and exposure correction information can be displayed on the print paper printed with a printing device that does not have the function of displaying the print number on the print paper. It is possible to obtain an excellent effect that the collation with the image printed on the printing paper becomes easy.
