Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a numbering method for printing a print number for identifying image scratches on continuous photographic paper on which a film image has been printed and developed, and to the implementation of the method. Concerning equipment for direct use.

[Conventional technology]

Continuous photographic paper, on which a negative film image is printed by a printing device, is developed by a developing device and then cut into individual images to be manufactured into products.

In the printing process in this printing device, the amount of printing exposure to the photographic paper is optimized to obtain the best printed image. That is, using a notch puncher, a semicircular notch is punched at the side edge of the negative film at a position corresponding to the image, and a notch is punched according to the average transmission density (LATD) obtained by photometrically measuring the image with a printing device. Information on the exposure correction amount for the exposure amount obtained is stored on a paper tape as a storage medium. Furthermore, this paper tape is loaded into a printing device, the negative film is transported in synchronization with the paper tape, and the presence of a notch is detected using a photoelectric switch, etc., and when the presence of a notch is detected, the transport is stopped and detected. The image scan corresponding to the notch is positioned at the printing position, and the exposure correction information stored on the paper tape is read and printed based on this information. After printing, the photographic paper is developed and then cut into individual prints by a finishing print cutter.

By the way, if the printed image is defective and the image needs to be reprinted, or if the customer checks the printed image after receiving the bagged photographic paper and orders a reprint, etc. It is necessary to make a correspondence between the image and the filter image and specify the color.

Therefore, it is conceivable to print a hook number corresponding to the image on the film on photographic paper to facilitate correspondence between the printed image and the image on the film.

In this case, it is possible to print the age number on the photographic paper along with the printing exposure process in the printing device, but since the printing exposure process in the printing device is done in a short time, it is difficult to print on the photographic paper. High-speed printing is required, and printing cannot be easily done using a printer with a slow printing speed.

Furthermore, even if printing is completed, the photographic paper is then immersed in a developer for development, which causes the disadvantage that the printed characters and symbols disappear or become faded. Furthermore, when printing is performed at the time of printing exposure, that is, when the image has not been completely developed, the sensitivity of the photographic paper changes due to the pressure during printing, and there is a possibility that desensitization fog may occur.

Therefore, it has been considered to print a hook number at the time when the finished photographic paper is cut for each image roll, and Junto Honde has already invented an invention regarding a finishing print cutter that is equipped with the function of printing the roll number ( (Special Application No. 150396/1982)
.

The finishing print cutter according to the present invention has the advantage that printed characters and symbols do not disappear or fade, and the quality of images printed on photographic paper is not adversely affected.

[Problem that the invention seeks to solve]

However, in order to add this printing function to an existing finished print cutter, significant modification is required, resulting in extremely high costs.

On the other hand, when printing on photographic paper after development using a standalone printing machine, the series of photographic printing and development processing lines from printing to development and cutting must be changed, and new methods such as continuous printing and rewinding of photographic paper are required. additional steps must be added.

In consideration of the above facts, the present invention makes it possible to print a print number at low cost and without changing a series of photographic printing and developing processing lines by using it together with an existing finished print cutter, thereby making it possible to print a print image. It is an object of the present invention to provide a numbering method and a numbering device that can easily specify the number of sheets by associating each cut of photographic paper with the corresponding image of a negative film.

[Means for Solving the Problems: Part 1] In the numbering method according to the present invention, images are printed on continuous photographic paper by a finishing print cutter that conveys the developed continuous photographic paper and cuts it for each image. A numbering device for printing a print number for identifying an image ripple on the continuous photographic paper is arranged on the upstream side in the conveying direction, and the continuous photographic paper is conveyed so as to form a loop between the two, and this loop is detected. The hook number is printed on the continuous photographic paper while controlling the conveyance speed of the finishing print cutter or the numbering device, whichever has the faster conveyance speed, so that a predetermined loop is formed.

[Effect]

In the numbering method with the above configuration, a numbering device for printing a frame number to identify the front of an image is placed upstream in the continuous photographic paper transport direction of an existing finishing print cutter for cutting the continuous photographic paper for each image roll. be done. A rack of continuous photographic paper is passed between each device, and the continuous photographic paper is conveyed so as to form a loop between the two devices. In this case, the continuous photographic paper is conveyed while controlling the conveyance speed of the finishing print cutter or the numbering device, whichever has the faster conveyance speed, so that a predetermined loop is formed by detecting this loop. Therefore, the difference in conveyance speed of continuous photographic paper is absorbed, and the finishing print cutter and the numbering device are not restrained by each other.

Continuous photographic paper, which is conveyed to form a predetermined loop, is printed with frame numbers by a numbering device, and then cut by a finishing print cutter for each image.

When comparing the printed image on the photographic paper after printing and cutting with the corresponding front image on the film, it is only necessary to use the frame number printed and displayed on the photographic paper to correspond with the film, making it easy to compare. Be able to do it.

[Means for Solving the Problems: Part 2] Furthermore, the numbering device according to the present invention includes a paper holding section that holds continuous photographic paper on which the image on the film is printed and developed and wound into a roll; a conveyance means for pulling out and conveying the continuous photographic paper held in the paper holding section from its outer periphery; and a detection means for detecting a loop of the continuous photographic paper formed at the end of the conveyance path of the continuous photographic paper conveyed by the conveyance means. a control means that is selectively connectable to the detection means and that, when connected to the detection means, activates or stops the conveyance means based on a detection result by the detection means; and a control means that identifies the image front of the film. It is equipped with a reading device that reads the frame number from a storage medium storing the frame number, and a printing device that prints the read frame number on continuous photographic paper.

[Effect]

The numbering device configured as described above is used by being connected to the upstream side of an existing finishing/printing cutter in the direction of continuous printing paper conveyance. After the continuous photographic paper is set in the paper holding section, it is sequentially pulled out from the outer periphery and conveyed by the conveyance means. At this time, the image exposure number of the film corresponding to the print image located at the printing position is read from the storage medium by the reading device. Furthermore, the read frame number is printed by a printing device on photographic paper on which the image has been printed. After printing, the continuous photographic paper is sent to a finishing print cutter, where it is cut into individual prints. In this case, a loop in the photographic paper is detected by a detection means arranged at the end of the continuous photographic paper transport path of the numbering device (that is, between the numbering device and the finishing print cutter). Here, if the numbering device has a faster conveyance speed than the finishing print cutter, the detection means is connected to the control means and this detection signal is supplied to the control means so that a predetermined loop length is achieved based on the detection signal. The conveying means is activated or stopped by. Therefore, the difference in conveyance speed of photographic paper is absorbed, and the numbering device and finishing print cutter are not restrained by each other.

On the other hand, when the conveyance speed of the numbering device is slower, the detection signal from the detection means is supplied to the finish print cutter, and the conveyance speed of the finish print cutter is controlled.

When comparing the printed image on the photographic paper after printing and cutting with the corresponding front image on the negative film, it is only necessary to correspond to the negative film by the frame number printed and displayed on the photographic paper, and it is easy to do. Verification can be performed.

A reading head 49 for reading the cocoon number stored on the paper tape 18 is attached to the paper tape reader 48. This reading head 49 is connected to a control circuit 44, and is adapted to input the read serial number signal to the control circuit 44.

A printing device 42 is arranged partially inside the numbering device 10 so as to correspond to the back side of the photographic paper 24 that is sent, and is capable of printing on the photographic paper 24. In this case, the print head of the printing device 42 is disposed in the same direction as the conveyance direction of the photographic paper 24, so that printing can be performed sequentially along the longitudinal direction of the photographic paper 24 as the photographic paper 24 is conveyed. This printing device 42 is connected to the control circuit 44 .

Further, a cut mark sensor 46 is disposed at a position corresponding to the upper surface of the photographic paper 24 being fed, and is further connected to a control circuit 44 . This cut mark sensor 46
The cut mark 35 made on the photographic paper 24 is detected in the printing device 22 and is manually inputted to the control circuit 44. The control circuit 44 operates the printing device 42 based on this cut mark detection signal, and when the presence of the cut mark 35 is detected, a hook number manually entered from the reading head 49 is printed on the back side of the image mark located directly above the printing device 42. is printed.

A buffer loop portion 59 is provided at the opposite end of the paper tape reader 48 of the numbering device 10, so that the photographic paper 24 conveyed by the conveyance roller 40 can be kept in a looped state.

In the buffer loop section 59, a light emitting section 60 serving as a loop detection means and a corresponding light receiving section 61 are disposed facing each other, so that the presence of the photographic paper 24 that has become looped after printing can be detected. ing. This light receiving section 61 is connected to the control circuit 44 via a switching device 47.

As shown in FIG. 8, the control circuit 44 includes a central processing unit (CP).

Further, a light receiving section 45 is connected to the human output port 56, and a light receiving section 61 is also connected via a switching device 47. By operating this switching device 47, the light receiving section 61 is connected to or disconnected from the input/output port 56, and the detection signal can be supplied only when the light receiving section 61 is connected.

The numbering device 10 having the above configuration can be connected to a finishing print cutter 11.

The finishing print cutter 11 is also provided with a paper holding section 74 that holds the photographic paper 24 wound into a roll, similar to the paper holding section 41 of the numbering device 10.
Similar to the paper holding section 41, a roll of photographic paper 24 can be set therein. Also, finishing print cutter 1
A plurality of conveyance rollers for conveying photographic paper 24 are arranged in 1, and is further connected to a control circuit 72. In this case, photographic paper 24 is also pulled out sequentially from the outer periphery and conveyed by conveyance rollers 70. It is now possible to do so.

Further, a light emitting section 73 and a light receiving section 75 are arranged in the center of the finished print cutter 11, and the light receiving section 75 is connected to the control circuit 72. The photographic paper 24 is conveyed in a loop between the light emitting section 73 and the light receiving section 75, and the light receiving section 75 can detect this loop.

If it is detected that there is no longer a loop, the cutter operation is stopped and the system waits until a loop is formed. Then, when a loop is formed, the light receiving section 75 detects this, and the cutter operation is started again. This process is repeated during continuous cutter operation.

When this finished print cutter 11 is used in connection with the numbering device 10, the photographic paper 24 sent out from the numbering device 10 can be constantly conveyed between the light emitting section 73 and the light receiving section 75. . In this case, since there is no loop, the detection outputs of these light emitters and receivers are ignored.

A cut mark sensor 76 is arranged at a position corresponding to the upper surface of the photographic paper 24 being fed, and a control circuit 72
connected to. This cut mark sensor 76 detects cut marks 3 made on the photographic paper 24 in the printing device 22.
5 is detected and input to the control circuit 72.

A fixed blade 78 and a corresponding movable blade 80 are disposed at the opposite end of the paper holding portion 74 of the finished print cutter 11, and are capable of cutting the fed photographic paper 24. This movable blade 80 is connected to the control circuit 72, and the cut mark sensor 7G is connected to the cut mark 3.
5 is detected, and the photographic paper 24 after printing can be cut into cocoons.

The control circuit 72 can be connected to the light receiving section 61 of the numbering device 10 via the switching device 47. Therefore, when using the numbering device, the switching device 47 is operated to connect the light receiving section 61, and the detection signal of the light receiving section 61 is supplied to the control circuit 72 instead of the detection signal of the light receiving section 75. There is.

Next, the operation of this embodiment will be explained.

The negative film 12 after development is passed through a notch puncher 16.
The exposure state is determined at , and exposure amount correction information at the time of printing is stored on the paper tape 18 together with the frame number. Further, an image is printed on the negative film 12 by a printing device 22. In this case, the paper tape 18 is conveyed in synchronization with the negative film 12, and the exposure correction information stored on the paper tape 18 is read by the reader 32 for each image exposure, and the filter 30 is controlled to print the image.

After printing, cant marks 35 are made on the photographic paper 24 by cut markers 34 at each gap between each image.

The image is printed by the printing device 22, and the photographic paper 24 with cut marks is developed in the developing device 38 and verified by the verification device 39, after which a frame number is printed for each image by the numbering device 10. At the same time, it is cut by a finishing print cutter 11.

In this case, by connecting the numbering device 10 upstream of the finish print cutter 11, printing of frame numbers and cutting can be performed continuously. In this case, operate the switching device 47 to switch the light receiving section 61 to the print cutter 1.
It is connected to the input port of the control circuit 72 of No. 1.

Of course, the output of the light receiving section 61 is numbered, the device 10
The input port 56 of the control circuit 44 is also connected to the input port 56 of the control circuit 44 .

In this case, this switching operation may be performed automatically based on a signal from the control circuit 44 at the same time as the numbering device 10 and the finished print cutter 11 are connected, as shown by the broken line A in FIG.

First, a case will be described in which the conveyance speed of the photographic paper 24 by the numbering device IO is faster than the conveyance speed by the finishing print cutter 11.

In the numbering device IO, the photographic paper 24 is set in the paper holder 41 as it is wound into a roll without going through a new process such as rewinding. In addition, 24 photographic papers
are sequentially pulled out from the outer periphery and conveyed by the conveyance roller 40, and the paper tape 18 is conveyed in synchronization with this. A frame number is printed on the back side of the photographic paper 24 by a printer 42 while being conveyed. FIG. 9 shows a control routine for the conveyance roller 40 and the printer 42.

When the numbering device 10 is activated, it is determined in step 100 whether the light receiving section 61 is in an off state (in other words, the loop end of the photographic paper 24 has reached the position of the light receiving section 61). Here, if the light receiving section 61 is in the on state, that is, the loop of the photographic paper 24 is not too loose at a predetermined length, the process proceeds to step 102 and the conveyance roller 40 is driven. Further, in step 104, the cut mark 35 is detected by the cut mark sensor 46. When the cut mark 35 is detected, the conveyance roller 40 is stopped in step 106, and the paper feeder 48 is stopped in step 108.
The frame number stored on the paper tape 18 is read by the reading head 49 . Thereafter, in step 110, the read frame number is printed on the back side of the photographic paper 24 by the printer 42.

Further, the process proceeds to step 112, where it is determined whether or not printing has been completed.If printing has not been completed, the process returns to step 100, and the above-mentioned routine is repeated again, and the process is completed. Further, if the cut mark 35 is not detected in step 104, the process similarly returns to step 100.

On the other hand, if the light receiver 161 is off in step 100, that is, the loop end of the photographic paper 24 has reached the light receiver 61 and is too loose, the process immediately proceeds to step 114, where the conveyance roller 40 is stopped and the photographic paper 24 is The loop of the photographic paper 24 is reduced so that the tip of the loop is located at the light receiving section 61. The process then proceeds to step 112 and the above-described routine is repeated.

The photographic paper 24 on which printing has been completed in this manner is fed to the finishing print cutter 11 in the form of a loop of a predetermined length (a length in which the tip of the loop does not reach the light receiving section 61) in the buffer loop section 59.

In the finishing print cutter 11, the cut mark 35 is detected by the cut mark sensor 76 while the photographic paper 24 is conveyed by the conveyance roller 70, and the photographic paper 24 is cut for each image. Figure 10 shows the finishing print cutter 1.
The control routine for the conveyance roller 70 and the movable blade 80 in No. 1 is shown.

When the conveyance roller 70 is driven in step 140, it is determined in step 142 whether or not the cut mark 35 has been detected. If the mark 35 is detected, step 14
4, the conveyance roller 70 is stopped, and then step 1
At 46, the movable blade 80 is operated to cut the photographic paper 24 by one image.

In this way, the printing of the print number in the numbering device 10 and the cutting of the photographic paper 24 by the finishing print cutter 11 proceed simultaneously, but the conveyance of the photographic paper 24 is based on the state of the loop-shaped photographic paper 24 in the buffer loop section 59. Since they are controlled, the difference in conveyance speed between the two is absorbed and they are not restrained by each other. The operation of the movable blade 80 of the finishing print cutter 11 is controlled by the cut mark sensor 7.
Since this is performed only when the conveyance roller 70 is stopped based on the cut mark detection signal No. 6, the photographic paper 24 will not be cut inadvertently in the middle of the image.

Next, a case where the conveyance speed of the photographic paper 24 by the finishing print cutter 11 is faster than the conveyance speed by the numbering device 10 will be explained.

In this case, the loop tip of the photographic paper 24 does not reach the light receiving section 61 and is too stretched! When IM6 is reached, the control circuit 72 stops driving the conveying roller 70, thereby controlling the buffer loop section 59 so that the photographic paper 24 has a predetermined loop length. Furthermore, each image is cut based on the cut mark detection signal of the cut mark sensor 76.

Photographic paper 24 cut by finishing print cutter 11
is almost completed as a product. In this case, a printed image that is judged to be poorly finished and needs to be reprinted by inspection can be easily verified because the print number of the negative film 12 corresponding to this image is printed on the back side. This improves the efficiency of reprinting work. Furthermore, when a customer re-orders additional prints or the like, he or she can easily specify the color of the print image. In the above example, the numbering device 10 and print cutter 11 are controlled to stop operating depending on the presence or absence of the loop 59, but in order to smooth the operation, it is effective to provide a time delay or hysteresis in actual control.

In this embodiment, the numbering device 10 and the finishing print cutter 11 are used in conjunction with each other.
Either the numbering device 10 or the finished print cutter 11 can be used alone. In this case, the loop tip detection signal from the light receiving section 61 is not supplied to the control circuit 44 or the control circuit 72, and the transport speed of the photographic paper 24 is controlled based on the detection signal from the light receiving section 45 or the 1j light receiving section 75. Ru.

〔Effect of the invention〕

As explained above, according to the present invention, by using it together with an existing finishing print cutter, it is possible to print a print number at low cost and without changing a series of photographic printing and developing processing lines, thereby printing images of printed images. This method has an excellent effect in that it is possible to easily specify the cut-off photographic paper and the corresponding image cut-off of the negative film by associating it with the cut-off photographic paper.
