Abstract

PURPOSE:To print a frame number on the back surface of a printed printing paper as a number for collating an original picture by extracting one frame number based on a selecting method according to visual judgement with the aid of an automatic means in the case of the plural frame numbers. CONSTITUTION:The frame numbers of a film and distances corresponding to them are previously decided and a judgement part which judges how the frame numbers of the film are positioned on the surface of the film based on the distance information between a bar code and the center of the original picture of the film is provided. When it is judged by the judgement part that two of the main and the sub frame numbers are displayed within the range of the original picture in the case that the size of the original picture is half size, the corresponding two bar codes 21 and 31 are read and the preceding small frame number is printed on the left side and the other frame number is printed on the right side. On the other hand, when the size of the original picture is full size that three frame numbers are displayed within the range of the original picture, the bar code corresponding to the central frame number is read and printed. In the case of the two frame numbers, the bar code corresponding to the small frame number is read and printed by comparing the frame numbers.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a photographic printing apparatus for facilitating comparison between an original image on a film and the printed image on photographic paper.

[Background of the invention]

When printing a large number of original images on film onto photographic paper, the original film is connected in series, and each frame of each image is successively printed onto a roll of photographic paper. It will be burned automatically.

After the photographic paper with the image printed on it is developed, it is cut into individual image units and delivered to the customer along with the original film.

[Problem that the invention seeks to solve]

By the way, when an improperly exposed image is discovered after processing and needs to be reprinted, or when additional prints are made in response to a customer's order, it is necessary to visually locate the original image on the film that corresponds to the image on the photographic paper. , when there are many similar images, it becomes extremely difficult to match them.

In order to deal with this problem, Japanese Patent Laid-Open No. 63-305336 and No. 63-30533 proposed a method of displaying the frame number written on each original picture on the film and the corresponding one on photographic paper.
The proposals in each publication No. 7 have been disclosed, but the present invention further proposes a photographic paper that is electro-optically most appropriate and that can display frame numbers in a format similar to that determined by visual recognition. The purpose is to provide a photo printing device for recording.

[Means for solving problems]

The above purpose is to create a film number in which a main number and a sub-number are displayed alternately at an interval of one frame of a half-size image, and to display a film number at a predetermined interval in the vicinity of and corresponding to the film number. A photographic printing device that prints a film image onto photographic paper, the barcode being displayed as a barcode; It has a code reading means, a calculation means for calculating the positional relationship between the barcode reading means and the image of the film, and also includes distance information set in advance between the film number and the barcode, a film size determination section, and a calculation means for calculating the positional relationship between the barcode reading means and the image of the film. a number determining section for determining the number of film numbers located in the film image width based on information from the means; and a film number determining section for determining the film number located in the film image width; recording means for recording a smaller number on the photographic paper when the number of pieces is determined to be 2 by the number of pieces judgment unit, and recording the center number on the photographic paper when the number of pieces is judged to be 3 by the number of pieces judgment unit; This is accomplished by a photoprinting device that has.

〔Example〕

An embodiment of the present invention is shown in FIGS. 1 to 5.

FIG. 1 shows a printer configured to be able to print the frame number of an original image simultaneously with printing on photographic paper on which an original image on a film has been printed using the recording method on photographic paper of the present invention.

The films F connected in series start from the film source winding section 1, pass through the accumulation guide section, stop intermittently on the negative mask 2, and then pass through the accumulation guide section to the film winding section 3.
It is wound up.

On the other hand, the long photographic paper P passes from the paper source winding section 4 through the accumulation guide section, stops intermittently on the printing frame 5 in synchronization with the film F, and further passes through the accumulation guide section and is wound up into the paper winding section 6. It will be done.

The original image of the film F stopped on the negative mask 2 is illuminated by a light source 7 and is transferred to the printing frame 5 by a projection lens 8.
The photographic paper P stopped above is exposed and printed, but the frame number of the original picture is read in advance by the reading device B-H of the Percod and stored in the storage means (
(not shown), and is obtained by converting the stored barcode onto the back side of the photographic paper by operating the printing machine N-P after printing on the photographic paper by the action of the control system. is printed.

Regarding the regulation of the exposure position of the film, it is possible to accurately position it by detecting the notch that is usually formed in the outer area of the frame, and the amount of film transport can be measured by using the space between the frames. Although these methods are well known, they are not directly related to the present invention, so their details will be omitted.

Regarding the reading device B-R, the previous applicant's Japanese Patent Application Laid-open Nos. 62-153094 and 62-153095,
The film reading device proposed in No. 62-153096 is used, and the printing machine NP is of the type that presses 7 to 9 thin lines through a printing ribbon.

The reading device B-R and the printing machine N-P operate as shown in the flow chart of FIG. 2 or 3 depending on the size of the original image and the position of the main frame number or sub-frame number displayed on the original image. Its action is controlled.

The center of the screen of the original image on the film has a control section (not shown) that detects a notch and identifies the center of the image at both ends of the original image. In addition, the film frame number and its corresponding distance are determined in advance, and a judgment is made to determine how the film frame number is positioned on the film surface based on the distance information between the barcode and the center of the film original image. Has a department.

When the size of the original image is half-size, and the judgment unit determines that two frame numbers, main and sub, are displayed within the range of the original, it reads the two corresponding barcodes and determines the main and sub frame numbers. Regardless, the preceding lower frame number is printed on the left and the other frame number is printed on the right.

The barcode may be read while the film is moving or while the film is stationary, or may be printed on photographic paper or simultaneously in a dot matrix. Furthermore, the printing location may be on the image side of the photographic paper (for example, in the case of a border, the margin of the border can be used).

From the point of view of the appearance of the print, it is preferable to print on the back side since the print will be within the image area in the case of borderless printing.

In Figures 4(a) and (b), main frame number 20 (10, 11) and sub-frame number 30 (IOA, I
This shows an example in which the above-mentioned judgment section determines that two frame numbers of IA) are displayed. In this case, the barcode 2 of each main frame number 20 is displayed by the reading devices B-H.
1 and the barcode 31 of each sub-frame number 30 are read, and the printing machine NP prints the frame number 1O-1OA, l0A11.1l-1 on the back side of the corresponding photographic paper P as shown in the figure.
1A or frame number l0A-11, 1l-11A,
List and print as 11A12.

Also, if either the main or sub-frame number is displayed within the range of the original image, read the corresponding barcode and place that frame number, for example, approximately in the center of the back of the photographic paper, regardless of whether it is the main or sub-frame number. Print.

Figure 4(C) shows main frame number 20 (1) within the range of each original picture.
1) or sub panel number 30 (IOA, IIA) 1
In this example, only one frame number is displayed, and in this case, the reading device B-R reads the barcode 21 of each frame number.
Or read 31 and write the frame number IOA,
11. IIA is printed separately.

On the other hand, in the case of a full-size original image in which three frame numbers including a main and sub frame number are displayed within the range of the original image, the bar code corresponding to the center frame number is read and that frame number is printed.

If the displayed frame number is 2, the frame numbers are compared, the bar code corresponding to the smaller frame number is read, and that number is printed.

Figures 5(a) and (b) show main frame number 20 (10,
11, 12) and sub frame number 30 (IOA, IIA, 1
2A) is displayed in total, and the barcode corresponding to the frame number in the center of each is read and the frame number 1 is displayed on the back of the corresponding photographic paper P as shown in the figure.
1.12 or printed as IOA or IIA.

In addition, Fig. 5(c) and (d) show main frame number 20 (
In this example, two frame numbers are displayed, one each of 10, 11) and sub-frame number 30 (IOA, IIA). In this case, read the barcode of the younger frame number. As shown in the figure, the frame numbers are printed as 10, 11 or IOA, IIA.

Note that when the main frame number 20 and the sub-frame number 30 are in the same unit, the main frame number 20 is determined to be the younger frame number.

〔Effect of the invention〕

When printing a photograph, when there are multiple frame numbers displayed on the original image on the film, the present invention extracts one frame number by automatic means using a selection method based on visual judgment, and selects the frame number. To provide a photographic printing device having a recording method on photographic paper capable of printing a number on the back side of the printed photographic paper as a reference number against the original image, and as a result, only one frame number is called out. By using a control system with simple functions, it has become possible to compare the original image with the photographic paper on which the image was printed during reprinting or reprinting, extremely easily and without error.

2 and 3 are flowcharts for printing frame numbers using the above recording method, and FIGS. 4 and 5 show the frame numbers displayed on the original image of the film and the frame numbers printed on the back side of the photographic paper. An explanatory diagram showing correspondence with frame numbers.
