Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a photographic printing apparatus, and more particularly to a photographic printing apparatus that prints the frame number of the corresponding frame of a negative film on the back side of a printed photograph. It is something.

[Conventional technology]

Most of the photographed negative film is normally used for simultaneous printing, where the film is developed and printed. In this simultaneous printing, the negative film is first developed and then each frame recorded on the negative film is printed and exposed on photographic paper to obtain a printed photograph. Also,
The negative film that has been printed and exposed is cut into negative pieces, for example every six frames, and these pieces are loaded into a negative sheet bag. Then, the negative sheet and the printed photograph are stored in a DP bag and handed to the customer.

In the above printing process, the average transmission density (LA
TD) is photometered, and the basic printing exposure amount of three-color light is calculated from this average transmission density. However, only about 70% of all printed photographs can be finished with proper density and color balance using this basic printing exposure amount alone, and the remaining 30% are subject to subject feria, which results in a poor finish. Becomes inappropriate. Therefore, for frames where this subject area occurs, exposure correction amounts for yellow, cyan, magenta, density, etc. are determined based on the operator's experience, and the basic printing exposure amount is corrected.

By the way, in simultaneous printing, one print photo can be produced for each frame of negative film, so if multiple print photos are required, a request for additional prints is made. In this 5-print printing, the operator is often different from that in simultaneous printing, and even if the operator is the same, the amount of exposure correction may be slightly different. For this reason, conventional reprints rarely produce the same results as simultaneous prints.

On the other hand, in order to easily create reprints with the same density and color balance as the printed photos obtained by simultaneous printing, frame numbers are printed on the back of the printed photos, and the negative pieces stored in the negative sheets are printed on the back of the printed photos. Tokuko No. 1-181446, Japanese Patent Application No. 2654, describes a frame number printing system that prints a frame number and an exposure correction amount on a negative sheet in correspondence with the position of each frame.
Kide-Applicant proposed this in No. 66, etc.

[Problems to be Solved by the Invention] However, in order to make the above system suitable for large-scale photo labs that process a large number of simultaneous prints, a large number of negative films are connected to form a long film, and this is used to efficiently develop the film. That's what I do. Therefore, a dedicated film splicing device, a printer, and a film cutting inserter are required, resulting in a large-scale device configuration. Therefore, there is a problem in that it is difficult to introduce the above-mentioned frame number printing system in small-scale photo labs that perform print processing on a one-off basis.

It is an object of the present invention to provide a photographic printing apparatus which solves the above-mentioned problems and allows the above-mentioned frame number printing system to be easily implemented even in a small-scale photofinishing laboratory.

[Means for Solving the Problem] In order to achieve the above object, the present invention provides a means for setting each frame on a photographic film at a print position, and detection of the film feed amount and frame number bar code at the time of setting. means for obtaining frame position data by specifying the frame number of a frame set at a print position based on a signal; and photographic paper based on the detected frame number.

means for printing a frame number on each print frame; means for identifying a cutting position for cutting the photographic film into film pieces based on the frame position data; and recording the cutting position on the photographic film; When a photographic film is cut at a certain position and inserted into a film sheet, the frame number of each frame and the exposure correction data used during printing exposure are stored in the same arrangement as each frame position of the photographic film in this film sheet. , and a printer for printing on reorder sheets.

[Function 2] During simultaneous printing with a printer processor used in small-scale photo labs, each frame of negative film is automatically or semi-automatically moved to five print positions by a film carrier.
The operator operates the frame advance key to advance the negative image). As is well known, this automatic frame setting to the printing position is performed by detecting the edge position of each frame by a screen sensor while the negative film is being transported, and based on the edge detection timing and the film feed amount.

Then, when setting the frames to this print position, the frame number barcode recorded on the side edge of the film is detected, and the frame number barcode is set to the print position based on the detection timing of the frame number barcode, the barcode reading signal, and the film feed amount. The frame number of the set frame is specified. after that,
The operator observes the image of the frame set at the print position and inputs exposure correction data. After this,
Printing exposure is performed.

Then, the cutting position of the photographic film is specified based on the frame position data specifying the position of the frame for each frame number,
Cut marks are recorded on the photographic film based on this cutting position. The photographic film is then cut into film pieces based on the 20 cut marks and inserted into the film sort.

Further, a reorder form is printed based on the cutting position and frame position data. This reorder form prints the frame number and exposure compensation data in the same arrangement as each frame when the film piece obtained by cutting the film at the cut mark is inserted into the film sheet. It is now easier to search for frames in a previous print, and exposure correction data used in simultaneous printing can also be easily obtained.

5 Embodiments] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram showing the configuration of a printer processor IO used in small-scale photo labs and the like. FIG. 2 is a perspective view showing the appearance of the printer processor 10 and the print printer 11 connected online thereto. Print printer 1
1 is based on print data from the printer processor 10,
Print the reorder form 12. This print printer 11 is configured in the same manner as a normal word processor printer, and can perform not only printing of characters, symbols, etc., but also front printing.

The printer processor 10 is composed of a printer section 13 and a processor section 14, as is well known. The printer unit 13 illuminates the frames to be printed on the negative film 15 set at the print position 19 by the film carrier 20 with light from a light source 23 whose light is adjusted by a filter adjustment unit 21 and made homogeneous by a diffusion box 22. The image of this illuminated frame is printed and exposed on a color paper 26 through a printing lens 24 and a shutter 25. Further, a printing device 28 is arranged on the exit side of the exposure position 27 of the color paper 26. The printing device 28 prints a frame number on the back side of the printed and exposed color paper 26 at a position corresponding to each print frame. As is well known, the processor section 14 includes a color developing tank, a bleach-fixing tank, a washing tank, a drying section, etc.
The printed and exposed color paper 26 is guided into each processing tank to undergo development processing. The color paper 26 after the development process is cut frame by frame and accumulated in the receiving tray 18 as printed photographs 29.

The film carrier 20 carries the negative film 15.
This is for automatically setting the negative film 15 at the print position 19, and there are three pairs of feed rollers 3 for feeding the negative film 15.
0 and a pulse motor 31 that controls the rotation thereof. The pulse motor 31 is controlled by a controller 33 via a driver 32. 5 and a film sensor 34 on the film side of the film carrier 20. Film tip sensor 351 Screen sensor 38. Frame number barcode sensors 39 are arranged in sequence, and signals from each of these sensors are sent to the controller 33.

The film sensor 34 detects whether the negative film 15 is set on the film entrance side of the first film feed roller pair 30. The film leading edge sensor 35 detects the leading edge of the negative film 15 during film transport. Further, the screen sensor 38 detects the edge of each frame 15A from the difference in density between each frame 15A of the negative film 15 and the blank area 15B between each frame 1.5A as shown in FIG.

The frame number barcode sensor 39 detects the frame number barcode 15C recorded on the side edge of the negative film 15. Incidentally, the reference numeral 37 in FIG. 3 indicates a change tape on which a ■D number is printed, which is attached to distinguish the negative film 15 from those of other orders.

Further, as is well known, a scanner 43 is arranged at a position facing the frame to be printed on the film carrier 20, and performs three-color separation photometry on each point of the frame, and a signal from this scanner 43 is sent to an exposure calculation unit 44. sent to. The exposure calculation unit 44 first calculates characteristic values such as the LATD and color correction coefficient value of the frame, and uses a well-known calculation formula based on these characteristic values and, if necessary, exposure correction data manually entered in the negative test. An exposure amount control value is calculated and sent to the controller 33. In the negative inspection, the operator observes each frame and operates the density key, color correction key, function key, correction key, etc. on the keyboard 33A for those that do not produce a satisfactory finish with the basic exposure amount based on LATD. This is done by manually inputting exposure correction data.

Further, a cant marker 46 is provided on the film exit side of the print position of the film carrier 20. This power marker 46 consists of a device that thermally transfers and records a triangular cut mark 47 shown in FIG. 3 on the side edge of the negative film I5. It's okay.

The controller 33 is composed of a well-known microcomputer, and connected to this is a keyboard 33A for manually inputting various commands, exposure correction data, etc., and a display 33B for displaying input data, command contents, etc. has been done. This controller 33 controls various parts in order to automatically feed the negative film 15, perform printing exposure, and specify the cutting position.

Hereinafter, while explaining the processing procedure of the controller 33 with reference to FIGS. 4 and 5, the operation of this embodiment will also be explained.

First, the leading edge of the negative film 15 is moved to the first feed roller pair 30.
Set it on the film entrance side of the camera. The controller 33 is
This film leading edge set is detected based on the film detection signal from the film sensor 34. Then, drive the pulse motor 31 to rotate the film feed roller pair 30,
The negative film I5 is sent toward the print position 19. During this film feeding, the controller 33 counts the number of driving pulses of the pulse motor 31 to detect the amount of film feeding from the time when the leading edge of the film is detected. Furthermore, the controller 33 feeds the negative film 15 by a fixed amount from the time when the screen is detected by the screen sensor 38.
Set the frame at print position 19. Further, the controller 33 detects the frame number barcode 5C recorded on the side edge of the negative film 15 using the barcode sensor 39, and specifies the frame number from the film feed amount and this barcode detection signal. The specific 5 pieces of this frame number are disclosed in Japanese Patent Application Laid-Open No. 63-305336 and Japanese Patent Application Laid-Open No. 1999-1
It is explained in detail in the publication No.-102539. Frame position data of each frame obtained in this way! Yo, memory 40
is temporarily written to a predetermined area within the .

After setting the frame to the print position 19, the operator observes the image of the frame and manually enters exposure correction data using the keyboard 33A as necessary. Further, if the frame position is deviated from the print' position, the frame position is finely adjusted by operating the fine adjustment key on the keyboard 33A. In this case, the controller 33 corrects the frame position data using the fine adjustment amount.

Further, the exposure correction data is sent to the exposure calculation section 44 via the controller 33. The exposure calculation unit 44 calculates characteristic values such as LATD and color correction coefficient based on the photometric values from the scanner 43, and then calculates an exposure control value using a well-known calculation formula using these characteristic values and exposure correction data. It is calculated and sent to the controller 33. The controller 33 calculates a filter set position from the exposure amount control value using a well-known filter calibration curve, and controls the filter adjustment section 21 and the shunter drive section 45 based on this position.

As a result, the frames of the negative film 15 are illuminated by the printing light modulated by each color filter, and the images of the frames are printed and exposed on the color paper 26. The controller 33 also stores the exposure correction data at the time of negative verification in the memory 40 for each frame.

Next, the controller 33 advances the printed and exposed color paper 26 frame by frame and sets a new unexposed color paper 26 at the exposure position 27, and during this frame advance, the printed frame of the color paper 26 is Correspondingly, the frame number of this frame is printed on the back side by the printing device 28.

The controller 33 also feeds the negative film 15 frame by frame in conjunction with the frame feed of the color paper 26.
By this frame feeding, the next frame is set at the print position 19.

Thereafter, the image of each frame is printed and exposed onto the color paper 26 one after another in the same manner. During this printing exposure, the controller 33 counts the number of frames and also calculates the number of frames from the time the leading edge of the film is detected! /) t is detected, and the cutting position of the negative film 15 is specified based on this. This cutting position is basically set between frames so that the negative piece has a length of six frames. However, in the case of the first negative piece, there is a blank frame, and since this blank frame varies depending on the camera model, its length is not constant. Therefore, as shown in FIG. 3, in the case of the first negative piece, the length is less than six frames, and within this length, the first cutting position S1 is set between frames 15A and 15A. decide.

Next, a second cutting position S2 is set between the 6th frame and the 7th frame from this first cutting position SL, and the film cutting positions are determined in the same manner every 6 frames. Then, when determining the first cutting position Sl, a calculation is made to calculate how many frames the final negative piece will contain when each six frames are cut one after another based on this first cutting position 1ls1, and this calculation is performed. If the final negative piece consists of only l frames, the first cutting position S1 is set between frames one frame before the initial position so that the final negative piece contains at least two frames. Make it. This is because in the case of a negative piece with only one frame, the negative piece becomes short and it becomes difficult to automatically set the frame at the print position during subsequent reprints, and this is done to avoid this.

FIG. 3 shows the cutting position S1. S2. This is an example of... These cutting positions zsl, S2. . . . Distance between iLl, L2. ... are these cutting positions 51S2.・
This is the film feed amount base Y$ value for attaching the cut mark 47 to . Data on the cutting positions Sl, S2, . . . are also stored in the memory 40 together with the frame position data.

Then, the controller 33 takes the installation position of the cut marker 46 as a reference and cuts the film 51i from this position:
The edge feed amount is detected, and when this feed amount reaches the feed amount reference value, film feeding is stopped and the cant marker 46 is driven to mark a cant mark 47 on the side edge of the negative film 15. Recording 3 After this, the controller 33 moves the feed amount standard 4M L to record the cut mark 47 on the negative film 15 at the next cutting position S2.
Update from L2 to L2. Thereafter, in the same manner, a cut mark 47 is recorded on the negative film 15 at the next cutting position S2 based on the updated feed amount reference value LW.

Further, after specifying the cutting position for one film, the controller 33 performs editing to create a reorder form, and based on this editing, creates the necessary information for printing the reorder form 12 as shown in FIG. Send the data to the print printer 11. Editing is done as follows.

Photons, frame number data of each frame, and exposure correction data are transferred to the cutting position 31. S2. Separate each... Next, each of these one section of data is brought to the side of the film insertion slot 61A of the negative sheet 61 and laid out in a right-justified state.

The printer 15 prints and creates a reorder form 12 based on the print data from the controller 33. Thereby, the display column 63 for each frame of the reorder form 12 can be laid out in accordance with the arrangement of the frames when the negative piece 62 is stored in the negative sheet 61.

Figure 6 shows full-size negative film 15 taken with 24 shots.
This figure shows an example of the reorder form 12 in the case where the negative sheet 62 is cut into five negative pieces 62 and inserted into the negative sheet 61. In each display column 63, frame number 64. Exposure correction data 652 and sheet number entry portions 66 are printed respectively. In FIG. 6, as shown in the display column 63 of the 18th frame, if printing exposure is not performed for a poorly photographed frame such as out-of-focus, the frame number and exposure correction data for this frame are not printed. In addition, in the reprint order form 12, the title section 6
7. In addition to the caution part 68, a film ID number part 69 with the same number as the ID number of the check tape 37 attached to the tip of the negative film 15 is printed, so that it can be distinguished from other orders. ing. Furthermore, this ID
Instead of the number section 69, an order number to be printed together with the frame number may be written on the back side of the printed photograph 29. In addition, the print number 8 in the ID number section 69 is printed on the keyboard 3.
3A, the operator inputs the ID number, but instead of printing, the operator can directly input the ID number.
You may also write a number.

The negative film 15 after all the frames have been printed and exposed is removed from the film carrier 20 and set in a well-known film cutting inserter 70, where the negative film 15 is cut at the recording position of the cut mark 47, and the negative piece 62 is cut. and stored in the negative sheet 61. Then, all the negative pieces 62 are placed on the negative sheet 61.
After being inserted into the DP bag 71, the negative sheet 61, the finished printed photograph 29, and the reorder form 12 are inserted into the DP bag 71 and handed to the customer. Note that instead of using the film canting inserter 70, the operator may cut the negative film 15 using the cant mark 47 as a guide and insert it into the negative sheet 61.

When performing reprints, the display column 63 with the same frame number printed on the reorder form 12 is found from the frame number printed on the back of each printed photo 29, and the required number is indicated in the number entry section 66. All you have to do is fill in the number and submit this reorder form 12 together with the negative sheet 61 to the photo lab, making it easy to issue additional prints. At the photofinishing laboratory, look for the display field 63 in which the desired number of prints is written on the reorder form 12, take out the negative piece 62 located at the same position as this display field 63, and move the frame at the same position as the display field 63 to the print position of the printer. , and perform printing exposure for the desired number of images. At this time, by using the exposure correction data 65 of the reorder form 12, it is possible to obtain a printed photograph with the same finish as the simultaneous printing.

In the above embodiment, the screen sensor 38 is provided on the film carrier 20, and each frame is automatically set at the print position 19 based on the screen detection signal from the screen sensor 38.
Instead, frames may be set in a semi-automatic manner in which the negative film 15 is fed frame by frame in fixed amounts by operating the frame feed key on the keyboard 33A. In this case as well, when the frame position is out of alignment, the operator operates the fine adjustment key and uses this fine adjustment key to correct the frame position data by the amount of frame advance.

In addition, in the above embodiment, the printer 1 prints on a blank sheet.
1 to print the table and create a reorder form 12, but in addition to this, common items such as the number of sheets, the title of frame 1, notes, etc. were printed in advance, and this printed A reorder form may be created using a sheet.

Effects of the present invention As explained above, the present invention has 1. The cutting position is specified from the frame position data during printing exposure, and a cant mark is attached to this cutting position. At the same time, a reorder form is created with the cutting position set to 14, so the film piece cut at the cut mark is It is possible to obtain a reorder form with the same layout as each frame when inserted into the sheet. Therefore, it becomes possible to introduce a frame number printing system similar to that used in large-scale photo labs with a simple configuration of adding a printing printer, and it is possible to easily order additional prints. In addition, it is easy to search for frames ordered for reprints at the photo lab, and by using the exposure correction data used when printing at the same time, the reprints have the same density and color balance as the photos at the same time. can be finished.
