Description

The present invention relates to a photographic printing method, in particular, an image pattern recorded on an original image film such as a developed negative film and a printed image on which the image pattern is printed. The present invention relates to a photographic printing method capable of easily collating with paper.

[Prior art]

2. Description of the Related Art Conventionally, there is known an automatic photographic printing apparatus used for printing a developed image recorded on an original image film such as a negative film, which is printed on a printing paper by 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.

The notch puncher has the function as a notch that punches 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 photometric measurement of the image with an automatic photoprinting device. ) Has a function as a puncher for punching information on the exposure correction amount with respect to the exposure amount according to (4) on a paper tape as a storage medium. This notch is used to position the image pattern at the printing position in the automatic photo printing device, and in the automatic photo printing device, the presence of the notch is detected by detecting the presence of the notch by the photoelectric switch while conveying the original image film. Sometimes, the conveyance is stopped and the image pattern corresponding to the detected notch is positioned at the printing position. In this way, since the notch is used as image bearing positioning information, the notch is punched corresponding to only the image bearing required for printing, and the notch is detected by the automatic photoprinting device to position this image bearing. Bake.

[Problems to be solved by the invention]

However, when printing development of some image areas fails (for example, exposure failure, color balance failure, etc.), it is necessary to reprint, but image areas similar to the original image film are continuously photographed. In some cases, it is difficult to find the pattern corresponding to the image pattern that has failed to be reprinted from the image pattern of the original image 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, it is conceivable to attach the image-side identification code to the printed photographic paper, but if the image-side identification code attached to the photographic paper is updated only every time a notch is detected, the original image film If you look at the whole image, it will not match.

The present invention has been made to solve the above problems, and provides a photographic printing method capable of easily matching an image pattern to be printed with a print of an original image film when printing is developed for reprinting or additional printing. The purpose is to do. Incidentally, as a technique related to the present invention, there are JP-A-56-128933 and JP-A-5-128933.
There is a technique described in Japanese Patent Laid-Open No. 6-128932.

[Means for solving problems]

In order to achieve the above object, the present invention is
A notch is punched corresponding to the image image required to be printed on each of a plurality of original image films in which the original image films of the book are connected by splice tape, and the notch is detected in the printing process to detect the image image. In the photographic printing method, in which the image of the image pattern to be printed after positioning is printed on the printing paper and the identification code for identifying the printed image is updated and printed on the printing paper, Before the process, the pass information is stored in a storage means other than the original film for storing the exposure amount correction information in correspondence with the image pattern that does not require the printing, and the pass information is detected and printed in the printing process. The identification code is updated and added to the photographic printing paper by adding the number of pieces of the path information to the updated identification code, and the splice tape is detected. Each time an istape is detected, an order code for identifying the order is updated and attached to the printing paper, and when the order code is updated, the identification code is set to an initial value and the identification code and It is characterized in that the order code is attached to the printing paper.

[Action]

According to the present invention, a notch is punched in the original film corresponding to the image pattern required for printing before the printing process. Further, corresponding to an image pattern that does not require printing before the printing process, for example, punching or the like stores path information for correcting and updating the identification code in a storage medium other than the original image film such as a paper tape. Then, in the printing process, the notch is detected to position the image pattern, and then the image of the image pattern to be printed is printed on the printing paper. At this time, image defects that do not require printing can be counted by the pass information. The exposure control during printing is performed by storing the exposure amount correction information in a storage medium other than the original film such as paper tape in correspondence with the image pattern to be printed in the verification work before the printing process, and correcting this exposure amount in the printing process. The information is read and the exposure amount obtained by detecting the average transmission density information of the original image film by an optical sensor such as a photodiode in an automatic photo printing apparatus is corrected.

In the printing step, an identification code for identifying the printed image is attached to the printed printing paper. This identification code is updated each time it is printed, and is corrected and updated according to the path information. This correction update is further updated by adding the number of pieces of path information to the updated identification code each time the path information is detected and printed. Since the identification code is corrected and updated in this way, the identification code corresponds to the image pattern recorded on the original film, and the image printed is printed from the identification code attached to the printed photographic paper. It is possible to easily confirm which pattern of the image pattern corresponds. Here, if a number is used as the identification code, and the initial value of this number is made to match the initial value of the exposure number previously exposed on the original image film in correspondence with the exposure of the image,
Since the identification code and the pattern number coincide with each other, the printed image and the image pattern of the original image film can be more easily associated with each other.

By the way, since an order (order) for re-baking is usually performed for each negative film, if an identification code relating to the order is further added, the efficiency of re-baking work for each order can be improved. Therefore, in the present invention, an identification code for identifying the printed image and an identification code (order code) for identifying the order of each film are attached, and the identification code for identifying the printed image is as described above. In addition to the update and correction update, the identification code for detecting the splice tape used for connection between the original films with one original film as one order and identifying the order each time the splice tape is detected. To update. As a result, even when a plurality of order films are continuous in the original film, the order change can be detected by detecting the splice tape used for film connection, and the identification code for each order can be updated. When the identification code for each order is updated, the identification code is set to the initial value.

〔The invention's effect〕

As described above, according to the present invention, since the identification code corresponding to the image pattern of the original image film is attached to the print even when the notch is provided in correspondence with only the required image pattern, the original image film is formed. It is possible to easily collate the image pattern of the image with the image of the print, which makes it possible to easily perform the re-printing selection work and the pattern designation when re-ordering.
In addition, since the order code for identifying the order is updated every time the splice tape is detected by further adding the order-related identification code, the efficiency of the re-printing work for each order can be improved. can get.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings. In this embodiment, a plurality of negative films are connected by a splice tape, a notch is punched corresponding to the image pattern to be printed, and the exposure amount is corrected corresponding to the image pattern to be printed (image pattern requiring printing). The present invention is applied when information is stored and printed.

FIG. 2 (A) is a diagram showing a schematic configuration of a printing optical system of the automatic photo printing apparatus used in the present invention. Film transport device
Reference numeral 10 has a function of conveying a developed original image film 18 such as a negative film and positioning an image side at a predetermined printing position 17. Therefore, in the transport device 10, the original film 18 is stopped by detecting the notch 36 (FIG. 2B) while transporting the film 18.

As shown in FIG. 2 (B), perforated tape (paper tape) 11
A plurality of holes 32 as exposure amount correction information of the image frame 18A to be printed and holes 30 as path information for the image frame 18C that does not require printing are provided in the. The hole 32 as the exposure amount correction information is provided corresponding to the image frame 18A (see the chain line). The hole 30 as the path information is provided corresponding to the image frame 18C that does not require printing. Note that the paper tape 11 is drawn in the lengthwise direction so as to correspond to the image pattern. Where the perforated tape
Like the perforation 18B provided on the original film 18, holes 11 (not shown) are formed along the longitudinal direction at both widthwise end portions of the original film 18 in synchronization with the conveyance of the original film 18. It engages with a sprocket wheel (not shown) of the reading device 13 that rotates and is conveyed and stopped in synchronization with the original image film 18.

The exposure amount correction information and the pass information are verified by a verification device before being printed by an automatic photographic printing device and punched on a perforated tape, and a notch puncher 34 is applied to this verification device ( See FIG. 2 (A). In the notch puncher 34, the notch function and punch function are used to punch and print the exposure amount correction information for correcting the density and color area in accordance with the image pattern to be printed on the punching tape 11. Image 18
A semicircular notch 36 is formed at a predetermined position near the edge of A. When the pass key of the notch puncher is pressed, the notch is not punched in the original image film, and the hole 30 as the pass information is punched in the punching tape. On the other hand, the original film 18 has a pattern number (generally an Arabic number or a combination number of Arabic number and alfa abet) near the edge of each image pattern 18A, 18C, which specifies the pattern for reprinting. It is used as a number.

As shown in FIG. 2 (A), a printing light source 19 is arranged below the printing position 17, and a yellow (Y) and a magenta (M) are provided between the film transport device 10 and the light source 19. A dimming filter 27 including complementary color filters for cyan and cyan (C) is arranged. The dimming filter 27 is controlled to have an exposure amount due to detection of the average transmission density information of the image area to be printed by a photometer (not shown), and the exposure amount stored in the perforation tape 11. Further correction control is performed by the control device 43 according to the correction information. A long photographic printing paper 33 is arranged above the film transporting device 10 via a printing lens 29 and a black-and-white shutter 31. Note that 33A is a supply roll for the photographic printing paper 33, 33B is a take-up roll thereof, and LS is an optical axis for printing.

A well-known numbering device 20 is arranged on the back side of the photographic printing paper 33, the number of which is applied as an identification code of the image pattern, and the image patterns 18A and 18C of the original film 18 pass through the printing position 17 (perforation tape 11). Is updated by the control device 43 each time the presence of the image pattern 18C is detected by the pass information of the image or the image pattern 18A is detected by detecting the notch 36 by the light receiving element 72), and at the time of the printing process (the presence of the notch is detected). (If detected)
The number is printed on the back side of the photographic printing paper 33.
It is preferable that this number is the same as the exposure number previously exposed on the edge of each image exposure of the original film 18 (in this embodiment, the same exposure number or a combination of the numbers and the alphabet), but they are compared with each other. If possible, it may be a code string with an order such as ABC or ILOHA. The numbering device 20 can also be provided with an identification code that is different from the identification code of the image frame 18A. The film identification code for identifying the original image film 18 is updated every time the splice portion of a plurality of original image films 18 connected by a splice tape and continuously conveyed is detected, and the original image film 18 is identified from the film identification code. It can be identified. When the film identification code for identifying the original image film 18 is updated, the identification code for identifying the image frame 18A is set to an initial value in conjunction with this.

The original film 18 is a film transport device depending on whether the path information stored in the perforated tape 11 and the presence of notches are detected.
Although the transportation is stopped by 10, the film transportation device 10
Is configured as follows.

As shown in FIGS. 3 and 4, upstream and downstream of the optical axis LS are arranged so as to correspond to the back surface (lower surface) of the negative film on which the transport rollers 22 and 24 are transported.
The transport rollers 22 and 24 are fixed to the rotary shafts 26 and 28, respectively, and are arranged in a direction perpendicular to the film transport path A when seen in a plan view.

The conveyor roller 22 has a pulley 38, and the conveyor roller 24 has a pulley 38.
40 are fixed to each other, and a timing belt 42 is stretched between these pulleys 38, 40. As a result, the rotary shafts 26 and 28 are rotated in the same rotational direction and at the same rotational speed when viewed in the axial direction.

A pulley 44 is fixed between the pulley 40 and the transport roller 24, and a part of the timing belt 46 is wound around the pulley 44.
The other part of the timing belt 46 is wound around a pulley 46, and the pulley 48 is connected to an output shaft 52 of a pulse motor 50 whose drive pulse number is controlled by the control device 43. Therefore, the pulse motor 50 transmits the rotational force to the rotary shafts 26 and 28 through the timing belts 46 and 42, and rotates the transport rollers 22 and 24 in the clockwise direction in FIG. 4 to the negative film on the film transport path A. It is designed to give a carrying force. The pulse motor 50 is controlled by the controller 43, which stops the transport of the original image film.

As shown in FIG. 3, a lower mask 64 is mounted below the film transport path A. This lower mask 64 has a first
The mask opening 68 and the second mask opening 70 are respectively penetrated.

Further, a pair of press rollers 114 and 116 are attached to the large arm 14 so that the original image film 18 is sandwiched between the large rollers 14 and the conveying rollers 22 and 24, respectively, so that the negative film can be conveyed when the conveying rollers 22 and 24 rotate. Has become. A mask stand 136 is fixed to the tip of the small arm 16. This mask stand 136
An opening 137 that is larger than the mask opening 140 is formed at the same time, and an upper mask 138 is attached.

A notch detection sensor 76 composed of a light-receiving element 72 and a light-emitting element 74 is arranged at both ends of the original film 18 at the printing position in the vertical direction of FIG. 4 with a slight distance from the side edge edges of the original film 18. Has been done.

On the optical axis from the light emitting element 74 to the light receiving element 72 emitted, the notch 36 is designed to pass when the original film 18 is conveyed, and the light receiving element output and light rays when the film is not present are the film. The presence or absence of the notch 36 can be discriminated by an electric signal from the difference from the light receiving element output when the light is shielded by the base. Further, since the light beam is completely blocked when the splice portion passes, the splice portion can be detected from this. Since the splice tape is usually narrower than the film width, it may be difficult to detect the splice part with the notch detection sensor.Therefore, a splice sensor having the same configuration as the notch detection sensor should be provided at the approximate center of the film transport path. Further, it may be provided.

The operation of this embodiment will be described below based on the identification code updating routine shown in FIG.

First, in step 100, the film identification code and the image identification code are initialized. It should be noted that the initial value of the image frame identification code is made to correspond to the number immediately before the frame number (normal number 1) corresponding to the leading frame of the original image film, and the film identification code is set to 1.

Next, in step 102, it is judged whether or not the punched tape 11 is set in the reading device, and when the punching tape 11 is set, in step 10
4, the original film 18 and the punching tape 11 are conveyed in synchronization with each other. Although the original film 18 and the perforated tape 11 are conveyed in the same amount in this embodiment, the conveying speeds may be different as long as they are synchronized.

When the conveyance is started in step 104, it is determined in step 106 whether the path information of the image pattern stored in the perforated tape 11 is detected. Since the conveyance of the perforated tape 11 and the conveyance of the original film 18 are synchronized, if the reading device detects the hole 30 provided in the perforated tape 11, that is, if the path information is read, the image image at that time is read. It can be said that 18C has passed the baking position.

When it is determined that the path information is detected in step 106, the count value C is incremented in step 108, and then it is determined in step 110 whether the splice portion is detected.

If it is determined that the splice part is detected, step
After shifting to 112 and setting the flag F (F = 1), the routine proceeds to step 116. If the splice portion is not detected, the process proceeds to step 115, the flag F is reset (F = 0), and then the process proceeds to step 116.

In step 116, it is determined whether or not the notch detection sensor 76 has detected the notch 36. When it is determined that the notch 36 has been detected, the image frame identification code is updated by incrementing it by 1 in step 117, and the count value C is added to the image frame identification code updated in step 118 and further modified and updated. In the subsequent step 119, the count value C is set to 0. When it is determined that the notch 36 has been detected, it is determined that the image frame 18A is to be printed, and in step 120 the original image film 18 is stopped at the printing position. At the same time, the transport of the punching tape 11 is also stopped.

Next, in step 122, the exposure amount correction information is read from the perforated tape 11, the exposure amount with respect to the average transmission density is corrected based on this information, and the printing process (exposure process) is performed in step 124. After that, the process proceeds to step 126. In step 126, the numbering device applies the image frame identification code and the film identification code to the photographic printing paper 33, and then in step 127, if it is determined that the flag F is reset, the process proceeds to step 132. If it is determined that the flag F has been set, it means that the end of one original film 18 is reached, and the film identification code is updated by incrementing it in step 129.
Next, in step 130, the image frame identification code is set to the initial value, and then the process proceeds to step 132.

In step 132, it is judged whether or not the film exists at the printing position. If the film exists, the process proceeds to step 104 and the above processing is repeated.

As described above, since the printed photographic printing paper 33 is provided with the identification code (the same number in this embodiment) which corresponds to the pre-exposed pattern number corresponding to each image pattern of the original film 18, it is reprinted. This makes it easy to sort out image patterns from photographic paper at times. Further, since the film identification code is also attached at the same time, it becomes easier to select the original picture film 18 itself.
