CONSTITUTION:Extents of exposure correction corresponding to respective frames of a negative film 54 are stored on a paper tape 52, and frame numbers displayed on the negative film 54 with a bar code 56 are read by a bar code reader and are stored on the paper type 52. When a photographic paper carrying driving device is operated to carry a photographic paper 36 in the direction of an arrow C, the paper tape 52 is also sent to a paper tape reading part 16, and carrying of the photographic paper 36 and the paper tape 52 is stopped when a detector 46 detects a cut mark displayed on the photographic paper 36. Next, the paper tape reading part 16 is operated to read the preliminarily stored frame number from the paper tape 52, and a printing part 22 is operated to print this frame number on the rear face of the photographic paper 36. Thus, even the photographic paper printed by the printer which has not the frame number display function can be collated with the film.

Description

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

[Conventional technology]

2. Description of the Related Art Conventionally, automatic photographic printing apparatuses have been known which are used to print a target image recorded on an original film such as a developed negative film onto photographic paper by developing and processing the image. When using this automatic photo printer, please use the verification device (
A verification operation is performed using a notch puncher (hereinafter referred to as a notch puncher), and based on the results of this verification operation, a printing process is performed using an automatic photo printing device.

That is, using a notch puncher, a semicircular notch is punched at the side edge of the original film at a position that corresponds to the image, and the average transmission density (LATD) obtained by photometrically measuring the image using an automatic photoprinting device. Information on the amount of exposure correction for the amount of exposure corresponding to the amount of exposure is perforated in the tape as a storage medium. Then, load the Giota tape into the automatic photo printing machine,
While transporting the original film in synchronization with the paper tape, the presence of a notch is detected using a photoelectric switch, etc. When the presence of a notch is detected, transport is stopped and the image corresponding to the detected notch is positioned at the printing position. The image is then printed based on the average transmission density and exposure correction information.

However, if some images fail to be printed and developed (e.g. due to poor exposure, poor color balance, etc.), it is necessary to reprint them. In some cases, it is difficult to locate the image-corresponding surface of the original film that failed to be reprinted. In particular, when processing a large amount of original film by connecting a plurality of films with splice tape, the efficiency of reprinting work for each order (one order) becomes extremely low. Furthermore, when a customer reorders reprints or the like, it is difficult to match the image quality of the print and the original film, making the process of specifying a cup complicated. In order to solve this problem, a printer has been proposed that attaches an image@identification code to printed photographic paper, as described in Japanese Patent Laid-Open No. 56-128933 and No. 56-128932. There is.

[Problem that the invention seeks to solve]

However, it is not possible to attach an image@identification code to prints printed by a printing device that does not have the function of attaching an image identification code, and as a result, the efficiency of verification for reprinting and reprinting is poor. Noko.

As described above, the present invention is capable of attaching an image-wise identification code to photographic paper printed with a printing device that does not have the function of attaching an image [fli separate code] to photographic paper. The purpose is to obtain a cup number printing device that can easily match the printed number.

[Means for solving problems]

In order to achieve the above object, the present invention provides a printing number printing device that prints a serial number on photographic paper after development, in which a delivery number is recorded together with exposure amount correction information that is read at the time of printing and corrects the exposure amount. The present invention is characterized in that it has a target number reading means for reading the target number from a storage medium, and a printing means for printing the target number read by the target number reading means on photographic paper.

[Effect]

According to the present invention, a target number stored in advance together with exposure amount correction information is read from a storage medium (for example, a paper tape) by the target number reading means. This read target number is printed on photographic paper by a printing means. At this time, the paper tape stores a target number for each frame along with exposure correction information corresponding to this target number, and reads the target number from this paper tape and transfers it to the photographic paper on which the corresponding image is printed. Since the number is printed, the target number of the negative film can be reliably displayed on the photographic paper on which the corresponding image is printed.

Therefore, when comparing the image on the original film with the image on the photographic paper, the desired target can be easily found in the original film by comparing the age number displayed on the photographic paper with the target number on the original film. Can be done. Furthermore, unlike conventional printing devices, the printing device is independent of the printer, so even photographic paper printed with a printer without a printing function can be given an age number to facilitate verification.

[Embodiments of the invention]

FIG. 1 shows a target number printing device 10 according to the present invention.
, a photographic paper supply section 18 , a photographic paper winding section 20 , and a printing section 22 .

The device main body 12 has a substantially rectangular parallelepiped shape, and a control keyboard 14 is arranged on the front side of the device main body 12. The number printing device 10 is controlled by the control keyboard 14.

A photographic paper supply section 18 is disposed above the paper tape reading section 16, and a photographic paper winding section 20 is disposed on the opposite side from the paper tape reading section 16.

The photographic paper supply section 18 is comprised of a support 24 erected from the rear back side of the main body 12, and a shaft 26 erected forward from the support 24. On this shaft 26, a long photographic paper 36 is wound onto a roll 28 and loaded onto the shaft 26.

Similarly, the photographic paper winding section 20 is composed of a support 30 erected from the rear side of the main body 12 and a shaft 32 erected forward from the support 30. An empty reel 34 is loaded onto this shaft 32. This empty reel 34 is rotated in the direction of arrow B in FIG. 1 together with the shaft 32 which is rotated by a driving means 35 (see FIG. 4). This drive means 35 is connected to the control section 13. The photographic paper 36 loaded in the photographic paper supply section 18 is pulled out and transferred to an empty reel 34 of the photographic paper winding section 20.
It is designed to be wound up.

Further, a roller 38 and a roller 40 are arranged on the upper surface of the apparatus main body 12, and the photographic paper 3 pulled out from the reel 28 is
6 is folded back by rollers 38, conveyed on the upper surface of the apparatus main body 12 in the direction of arrow C, bent by rollers 40, raised up, and wound onto a reel 34.

Further, a pair of presser levers 42 are arranged on the upper surface of the apparatus main body 12 for guiding both sides of the photographic paper 36 in the width direction onto the upper surface of the apparatus main body 12.

Further, a detector 46 is arranged on the upper surface of the apparatus main body 12 to detect a cut mark 44 (see the second part) displayed between the images on the back side of the photographic paper 36. This cut mark 44 is an indication for cutting each image printed on the photographic paper 36. Further, a detector 50 for detecting a sort mark 48 (see FIG. 2) displayed on the back side of the photographic paper 36 is arranged opposite to the detector 46.

By detecting this sort mark 48, each unit of film order can be identified.

A printing unit 22 is located in front of the roller 40 in the conveyance direction of the photographic paper 36.
is located. This printing section 22 is connected to a control section 13 built into the main body 12 of the device (see Fig. 4).
.

The position of this printed portion 22 is determined by the detector 46 at the cut mark 4.

A zigzag tape 52 is fed to the zigzag tape reading section 16 in the direction of arrow A in the figure by a drive device 53.

This feeding is synchronized with the conveyance of the photographic paper 36 on the upper surface of the apparatus main body 12.

As shown in FIG. 3, this tape 52 stores the amount of exposure correction corresponding to each frame of the negative film 54. The amount of exposure correction is visually determined using a notch puncher and stored on the paper tape 52.

When the amount of exposure correction is determined using this notch-buncher, the exposure number displayed on the negative film 54 by a bar code 56 is read by a bar code reader and stored on the paper tape. The exposure amount correction information is read when an image from an original film is printed onto photographic paper by a printing device, and the exposure amount at the time of printing is corrected.

Further, the frame number of each frame is read by a paper tape reading section 16. Further, this paper tape reading section 16 is connected to a control section 13 built in the device main body 12 (
(See Figure 4).

Note that the positions of the punched holes in the paper tape 52 shown in FIG. 3 are shown expanded to correspond to each image of the negative film 54, and in reality, they are punched at short intervals.

Next, the operation of this embodiment will be explained using the flowchart shown in FIG.

A long photographic paper 36 wound into a roll on the reel 28 is loaded into the photographic paper supply unit 18 and pulled out, and then

At this time, the intermediate portion of the photographic paper 36 is guided onto the upper surface of the apparatus main body 12 by the presser lever 42 and set so as to pass between the printing section 22 and the upper surface.

Further, the photographic paper 36 is set with its back side facing upward.

Further, the paper tape 52 is transferred to the paper tape reading unit IQ, and the photographic paper 36
It is set starting from the part where the film number is stored, which corresponds to the first target. In this case, since the print number at the beginning of the paper tape 52 corresponds to the mark at the beginning of the photographic paper 36, it is sufficient to set the respective leading portions together.

From this set state, in step 60, the photographic paper conveying drive device 35 is activated and the photographic paper 36 is conveyed in the direction of arrow C. At the same time, the drive device 53 is activated and the paper tape 52 is sent to the paper tape reading section 16. The detector 46 detects the cut mark 44 displayed on the photographic paper 36 in step 62.
It is determined whether or not it has been detected. If it is not detected, the process returns to step 60 and the photographic paper 36 and tape 52 are conveyed. When the detector 46 detects a cut mark, the conveyance of the photographic paper 36 and the tape 52 is stopped in step 64. Next, in step 66, the tape reading unit 16 is activated to read the pre-stored age number from the paper tape 52. In step 68, the printing unit 22 is activated and the target number read in step 66 is printed on the back side of the photographic paper 36. In step 70, it is determined whether the paper tape 52 is being supplied to the paper tape reading section 16. If the paper tape 52 is still being supplied, the process returns to step 60 and the following program is repeatedly executed. If paper tape 52 is not supplied, the process ends.

In this embodiment, printing on the back side of the photographic paper 36 is performed in a direction perpendicular to the conveying direction of the photographic paper 36.
Printing may be performed in the opposite direction to the conveyance direction along the conveyance direction of No. 6. In this case, printing can be performed while the photographic paper 36 is being transported without having to stop once for printing.

〔Effect of the invention〕

As explained above, the present invention can reliably display the target number of the original film on the photographic paper (photograph) on which the corresponding image is printed, and does not have the function of displaying the target number on the photographic paper. Since the heir number can also be displayed on the photographic paper printed by the printing device, an excellent effect can be obtained in that it becomes easy to compare the image on the original film with the image printed on the photographic paper.
