Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic printing apparatus for facilitating discrimination between a printing paper having an image printed on an original film and an original film having the image.

[Prior Art] When an image frame is printed on photographic paper using the original film, the photographic paper on which the image frame has been printed is developed and then delivered to the customer together with the original film.
Also, when processing a large amount of original film, multiple original films are connected in series for printing.
On the other hand, the photographic printing paper is drawn out from a rolled-up portion to sequentially print image frames, and is cut into image frames after development processing.

[Problems to be Solved by the Invention] However, since the printed photographic paper has no means for distinguishing it from the original film, an operator visually confirms the image and associates the photographic paper with the original film.

Furthermore, if the printing density is inappropriate, it is necessary to reprint the image frame, but even in this case, it is necessary to visually check the image on the photographic paper and find the frame of the original film that has this image. Occurs. Also, when the customer brings the photographic paper and the original film and reorders, it becomes necessary to visually find the frame of the original film having the image of the photographic paper.

SUMMARY OF THE INVENTION In consideration of the above facts, an object of the present invention is to obtain a photographic printing apparatus capable of easily identifying an image frame corresponding to an image on photographic paper from a photographic film.

[Means and Actions for Solving Problems]

The present invention provides a film in which a main number and a sub number are alternately displayed in advance at intervals of one frame of a half-size image and a bar code corresponding to the main number and the sub number is formed in the film manufacturing process. Before printing the half-size original film image photographed and developed using photographic paper on the photographic paper, the reading means for reading the bar code and the main number or sub-number correspond to the lateral middle part of the printing image frame. If the main number or the sub number is recorded, the frame number information read from the bar code corresponding to the main number or the sub number is recorded. A recording means for recording the frame number information read from the bar code corresponding to both the main number and the sub number, and a display means for displaying these frame numbers on the photographic paper by the information of the recording means. It is characterized in Rukoto.

In the process of manufacturing a photographic film, a main number and a sub number are alternately displayed in advance on the side of the image frame area at intervals of one frame of a half-size image. On the other hand, the exposure position on the film of the captured image (full size or half size) is not constant due to the initial film winding position in the camera, so the captured image after film development corresponds to the main / sub number. Relationships are not constant.

Therefore, when the captured image is a full-size image that is twice as large as the half-size image, the main number or the sub-number always exists in the lateral intermediate portion of the image,
It is possible to easily identify which full-size image is by specifying the main number or the sub-number corresponding to the side of this full-size image. However, when the captured image is a half-size image, the length of the half-size image and the interval between the main and sub-numbers are the same. There are cases where the main and sub numbers correspond, and cases where the main and sub numbers do not correspond (cases where the main and sub numbers correspond only between half-size images).

In the present invention, when the main / sub number corresponds to the lateral middle part of the half-size image, the recording means records the frame number information read from the bar code corresponding to the main number or the sub number, When the main and sub numbers correspond to both lateral ends of the size image, the frame number information read from the bar code corresponding to both the main number and the sub number is recorded and displayed by the information of this recording means. The means can specify the image frame of the original film corresponding to the image frame on the photographic paper by displaying these frame numbers on the photographic paper. Therefore, in order to specify the image on the negative film, the bar code corresponding to this main / sub number can be searched to identify the image frame of the original film.

The display of the main number or the sub-number on the photographic paper by the display means may be performed by displaying the numbers directly, or by a special symbol such as an alphabet or a plurality of dots. This display is not limited to the back side of the photographic paper, but may be displayed around the image frame or in a portion outside the image frame.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the Invention FIGS. 1 and 2 show the longitudinal intermediate portions of photographic films 10 and 12 applied to the present invention.

The photo film 10 is a 135 mm film, and full-size image frames 14 (14A, 14B ...) Are printed in series at regular intervals.

A large number of perforations 16 and 18 are formed at regular intervals in the vicinity of both sides of the photographic film 10 for engaging and feeding with a sprocket (not shown). A large number of bar codes 20 having the same shape are formed at regular intervals between the side edge of the photo film 10 and the perforation 18 at the time of manufacturing the film. These bar codes 20 indicate the manufacturer of the photo film 10, the manufacturing lot number, and the like.

Main frame numbers 22 are formed at regular intervals between the bar codes 20 and between the other side edge of the photographic film 10 and the perforation 16 at the same position in the longitudinal direction of the film when the film is manufactured. Main frame numbers 22 on both sides in the width direction of the photographic film 10 are the same pitches as the pitch where the image frame 14 is formed, and an integer starting from "1" is displayed from one side of the photographic film 10 in order. The sub-frame number 24 is a half pitch of the display pitch of the main frame number 22 and is displayed at a position shifted to the right in the drawing by a half pitch from the main frame number 22. The sub-frame number 24 is displayed by adding "A" to the number of the main frame number on the left side immediately in the figure.

Bar codes 26 and 28 corresponding to the main frame number 22 and the sub-frame number 24 are formed between a plurality of main frame numbers 22 on one side (upper side of the drawing) of the film at the film manufacturing stage.
These bar codes 26 and 28 are displayed at positions separated from the main frame number 22 and the sub frame number 24 by a predetermined length on the right side of the drawing. Therefore, the numbers of the main frame number 22 and the sub frame number 24 can be detected by reading these bar codes 26 and 28.

FIGS. 1 (A) to 1 (E) show the case where the image frame 14 is printed onto the photographic film 10 while being sequentially shifted to the right. In FIG. 1 (A), image frame 14A is displayed as "11", but main frame numbers 22 and 12 are displayed as main frame numbers.
Since it is burned in between 22, the sub-frame number 24 displayed as "11A" corresponds to the central portion of the image frame 14A. Therefore, in this case, if the sub-frame number 24 indicated by "11A" corresponding to the image frame 14A is displayed on the photographic paper on which the image frame 14A is printed, the image frame 14A can correspond to the image on the photographic paper.

Further, in FIG. 1 (B), each image frame 14 is in a printing state in which it is slightly shifted to the right from FIG. 1 (A).
Main frame numbers 22 displayed by "12" to "15" correspond to the sides of each image frame 14, respectively. FIG. 1 (C)-
(E) shows the case where each image frame 14 is printed with a slight amount gradually shifted to the right from the state of (B), and in each case, the main frame number 22 is on the side of the image frame 14.
Is displayed, the identification can be performed by displaying the main frame number 22 corresponding to the printed printing paper.

The numbers in parentheses shown in each image frame in Fig. 1 are
It is the number written on the photographic printing paper of the image frame.

FIG. 2 shows a state in which half-size image frames 30 (30A to 30I) are sequentially formed. These image frames 30 are image frames 14 whose dimensions in the longitudinal direction of the film are shown in FIG.
1/2 of the longitudinal dimension of.

In the state of FIG. 2 (A), neither the main frame number 22 nor the sub frame number 24 corresponds to both sides of the image frame 30 (vertical direction in FIG. 2). The frame number 24 corresponds to the side between the image frames 30. Therefore, each of the image frames 30 is displayed by displaying the main frame number 22 and the sub-frame number 24 before and after the image frame 30 (left and right direction in FIG. 2) on the printed printing paper. Can be specified.

As an example, the image frame 30A at the left end of FIG.
It can be specified by displaying both the main frame number 22 displaying "1" and the sub frame number 24 displaying "12".

2 (B) to 2 (E), each image frame 30 is sequentially shifted from the state of FIG. 2 (A) to the right and printed onto the photographic film 12. In each of these cases, since the main frame number 22 or the sub-frame number 24 corresponds to the side of each image frame 30, these may be displayed on the back surface of the printing paper.

The numbers in parentheses shown in each image frame in Fig. 2 are
It is the number written on the photographic printing paper of the image frame.

In this way, in the case of full-size image frames 14, the main frame number 22 or the sub-frame number is placed on the side of these image frames 14.
Since 24 is always supported, if the main frame number 22 or the sub-frame number 24 is displayed on the photographic paper, the image frame 14 on the photographic film 10 can be supported, and in the case of the half size image frame 30, the image frame 30 There is a case where the main frame number 22 or the sub-frame number 24 corresponds to both sides of the, and a case where the image frame 30 enters between the main frame number 22 and the sub-frame number 24. The image frame 30 on the photographic film 12 can be specified by displaying at least one of them.

FIG. 3 shows a main part of a puncher 40 to which the present invention is applied. In this puncher 40, the developed photographic film 10 or photographic film 12 is fed in the direction of arrow A, and the image frames 14 and 30 thereof are sequentially arranged on the optical axis 42. A light source 44 and a light diffusion tube 46 are arranged above the optical axis 42 to illuminate the image frames 14 and 30 on the optical axis.
