A hole puncher 72 to store frame information is connected to the control part 66 via driver 71, and arranged in accordance with the rear side of the photographic paper 16. In a cutting part between the image frames which are printed onto the photographic paper 16 in synchronization with carriage of a negative film 32, the hole puncher 72 pierces a hole corresponding to data on both exposure correction in printing process and frame number. Thus, the information stored by the punched hole accords with the information synchronized with printing process; and the punched hole is read after development.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a frame information storage method for storing frame information of photographic film.

[Prior art]

Generally, after a photograph is taken, so-called simultaneous printing is performed in which the photographic film is developed and printed at the same time. When a customer orders additional prints, they look at the negative film to find the frame number corresponding to the desired print, and place an order using that frame number. When specifying this frame number, if similar images are stored in succession on a negative film, it is difficult to find the desired surface image, leading to the problem of making a mistake in ordering.

For this reason, it has been proposed in the past to provide a printing device in the printing device and print frame numbers corresponding to the images on the negative film onto photographic paper (for example, in Japanese Patent Laid-Open No. 56-128
932 and 56-128933).

According to this, the corresponding frame number is printed, for example, on the back side of the photographic paper, so the frame number can be easily specified when placing an order. Furthermore, by printing the corrected exposure amount during the printing process at the same time as the frame number, it is possible to match the finished image when reprinting and the finished image when simultaneously printed. Hereinafter, such frame number and corrected exposure amount will be referred to as frame information.

However, since the printing apparatus described above prints using the dot impact method, there is a problem that, especially in high-speed printers, the latent image is destroyed by the embossing pressure of the print head in the printing section, causing desensitization. Furthermore, if the printing device is of a type that does not apply pressure to the photographic paper, such as an inkjet method or a thermal transfer method, the above problem can be solved, but there is a limit to the printing speed. Also, maintainability is poor.
There are many consumables such as ink ribbons and ink, which increases costs.

For this reason, it has been considered to print on the back side of photographic paper after the photographic paper is developed. That is, after development, the image on the surface of the photographic paper does not change, and even if the dot impact type printing device described above is applied, the problem of latent image destruction can be solved.

In this case, frame information to be printed on photographic paper is generally read from a paper tape on which exposure conditions for negative film are stored to control the printing device.

[Problem to be solved by the invention]

However, a control negative may be used during the printing process so that the printing process is performed without regard to the information stored on the paper tape. Furthermore, due to synchronization errors, snagging of the negative film, etc., the negative film and paper tape may be returned once and the same image is printed again.

In such a case, the frames stored on the paper tape and the frames of the image recorded on the photographic paper roll will be incorrect.
Even if you try to print frame information on the back side of the photographic paper for the frames stored on the paper tape by applying the paper tape as is, it will not match the actual image (1).

The present invention has been made in consideration of the above-mentioned facts, and an object of the present invention is to provide a frame information storage method that can appropriately store frame information of a photographic film in image frames printed on photographic paper.

[Means to solve the problem]

The frame information storage method according to the present invention is characterized in that frame information including at least exposure information and frame information is directly stored in a predetermined location other than the image surface of an image frame printed on photographic paper during photo printing.

[Effect]

According to the present invention, the image information of an image frame that has been printed on photographic paper is stored by recording it, for example, by printing, on a portion of the photographic paper other than the printed image. It is possible to reliably match an image with the frame information corresponding to this image. The portions other than the image include the portions that are cut off when the photographic paper is cut into images, and the edges of the images if they have edges.

〔Example〕

FIG. 1 shows a photographic printing apparatus 10 to which the present invention is applied. The printing light RL of the light beam irradiated from the light source 12 of the photographic printing apparatus 10 has a print mask 1 on the top thereof.
4 are arranged, holding a part of the rolled photographic paper 16,
It is fixed at the burn-in position. Both rolls of photographic paper 16 are wound up in layers around rotating shafts 18 and 20, and downstream of print mask 14, a pair of conveyance rollers 22 are arranged.
are installed to sandwich the photographic paper 16. Conveyance roller 2
2 is rotated by the driving force of the motor 24 in the direction of the arrow in FIG. It is configured to be wound up.

The photographic paper 16 between the unwinding rotating shaft 18 and the print mask 14 is wound around a tension roller 26 . Further, a tension roller 28 is disposed downstream of the conveyance roller 22, and the photographic paper 16 is wound around the tension roller 28. These tension rollers 26, 28 are movable in the direction perpendicular to their axes, and are designed to maintain a constant tension during conveyance of the photographic paper.

A negative mask 30 is disposed on the printing optical path below the print mask 14, and holds a portion of a long negative film 32 and fixes it in a predetermined position. negative film 3
2, both of which are wound up in layers around rotary shafts 34 and 36, and a pair of transport rollers 38 are installed downstream of the negative mask 30 to sandwich the negative film 32. The conveyance roller 38 is rotated in the direction of arrow B in FIG. 1 by the driving force of the motor 42, and pulls out the negative film 32 from the outer periphery of one layered winding ms (left winding section in FIG. 1) and transfers it to the other rotating shaft. 36.

The negative film 32 between the unwinding rotating shaft 34 and the negative mask 30 is wound around a tension roller 44 . Further, a tension roller 46 is provided downstream of the conveyance roller 38, and the negative film 32 is wound around the tension roller 46. These tension rollers 44 and 46 are movable in a direction perpendicular to their axes, and are designed to maintain a constant tension during production and feeding of the negative film 32.

A printing lens 47 and a black shutter 48 are arranged between the negative mask 30 and the print mask 14. The black shutter 48 can be inserted into or removed from the optical path according to a drive signal from the driver 50. Furthermore, cut filters 52, 54, and 56 for each color of C (cyan), M (magenta), and Y (yellow) are arranged between the negative mask 30 and the light source 12. These cut filters 52, 54, 56 are inserted or removed from the optical path depending on signals from drivers 58, 60, 62, respectively.

A light receiver 64 is disposed diagonally above the negative mask 30. The light receiver 64 detects the density information of the image taken on the negative film 32 positioned on the negative mask 30 and supplies the detected value to the control section 66 . The control section 66 calculates the exposure amount based on this density information, and controls the black shutter 48 and cut filters 52, 54, and 56 according to the calculation result.

A paper tape reader 68 is connected to the control section 66 . A paper tape 70 is loaded in the paper tape reader 68, and the paper tape reader 68 reads the frame number etc. stored on the paper tape 70 and supplies the information to the control B66. The paper tape 70 stores frame numbers of the negative film 32 and sort marks representing the seams of each order, and are read out sequentially in synchronization with the conveyance of the negative film 32.

Further, a hole puncher 2 for storing frame information is connected to the control unit 66 via a driver 71. This hole punch 2 is arranged correspondingly to the back side of the photographic paper, and is stored on the paper tape 70 at the cut 6th minute 16A (see FIG. 5) between the image frames to be printed on the photographic paper 16. A punch hole 74 corresponding only to the frame number and exposure correction data during printing processing is punched. As a result, the information stored by the punch holes 74 is matched with the information synchronized with the printing process. This punch hole 74 is read after development is completed.

As shown in FIG. 2, the printing machine 75 is disposed downstream of the printing device 1o via a processor (not shown) (device for developing, fixing, washing, and drying the stamp paper).

The developed photographic paper 16 is loaded onto the rotating shaft 78 of the supply section 76 . The leading end of the photographic paper 16 is pulled out from the outer periphery of the photographic paper 16 and wound around a rotating shaft 82 of a winder R80. The rotation shaft 78 of the supply section 760 and the rotation shaft 82 of the take-up shaft 80 are driven by the driving force of motors 84 and 86, respectively.
The photographic paper 16 is rotated in the direction of the arrow C in the figure, and thereby the photographic paper 16 is conveyed in the direction of the arrow in FIG.

The printing machine 75 includes a tension roller 89, two pairs of drive rollers 90.92, and a print head 94 disposed between these drive rollers 90.92. 16 and is controlled via the head driver 96. It is connected to the B section 98. In control n98, the punch hole 74 is read by a punch hole reading section 100, which will be described later, to decipher the frame information, and the head driver 96 is controlled to operate the print head 94. This punch hole 74 is formed in the cut portion 16A of the photographic paper 16 during the printing process in the printing apparatus 10.

The drive rollers 90 and 92 are each rotated by the driving force of the motor 104, and nip and convey the photographic paper 16. Upstream of the print head 94, there are a cut mark sensor 108, a sort mark sensor 110, and a paper splice sensor at predetermined positions with distances 3, L2, and Ls from the print head 94 corresponding to the surface of the photographic paper. 112 are arranged, and the signal line of each sensor is connected to the control section 98.

Here, in the printing machine 75, the cut mark sensor 108,
Sort mark sensor 110, vapor splice sensor 1
By detecting each mark by the print head 12, the image on the photographic paper 16 and frame information such as its frame number and exposure correction data can be printed by the print head. In addition, in the control B98,
A display 5114 that displays frame information read from the punch hole reading section 100 is also connected.

The operation of this embodiment will be explained below.

First, the burn-in control will be explained according to the flowchart shown in FIG. It is assumed that frame information such as the frame number of each image frame is stored in the paper tape 70, and loading into the paper tape reader 68 is completed.

In step 150, the photographic paper 16 and the negative film 32 are transported, and the print mask 14 and the negative mask 300 are positioned at predetermined positions, respectively. Next step 15
2, frame information is read from the paper tape 70 by the paper tape reader 68, and then in step 154, the frame information is read from the paper tape 70.
The exposure amount is calculated from the detection signal from 4 and the frame information. Note that this exposure amount is determined for each color.

In the next step 156, the blur shutter 48, cut filters 52, 54 .
56 and performs the printing process. As a result, the light rays emitted from the light source 12 are transmitted through the negative film 32, and the transmitted image is printed onto the photographic paper 16.

When the printing process is completed, the process moves to step 158, where the exposure correction data and frame number at that time are determined by the hole punch 2 so that the punch holes 74 are aligned with the cut portion 16 of the photographic paper 16.
If the printing process fails for some reason and you want to continue printing the same negative image, transport only the photographic paper by a predetermined amount (for one frame) and perform the printing process again. However, the cutting portions 16A are sequentially drilled in such a case as well. Also, using a control negative,
Even when the printing process is performed regardless of the information stored on the paper tape 70, the cutting portion 16A is perforated in correspondence with the storage (a number or symbol indicating that it is a control negative). Note that such failed image frames and control negative image frames are punched with frame information as well as punch holes indicating that printing is not required.

In the next step 160, it is determined whether or not the printing process for all the negative films 32 has been completed. If the determination is negative, the process moves to step 150 and the above process is repeated.

After completing the printing process, the photographic paper 16 is sent to a processor for developing, fixing, washing, and drying, and after each process is completed, it is loaded into a printing machine 75. Printing control in the printing machine 75 will be described below according to the flowchart in FIG.

First, the photographic paper 16 is loaded onto the rotating shaft 78 of the supply section 76, and the leading end of the photographic paper 16 is pulled out from the outer periphery of the photographic paper 16.
It is wound around the rotating fIh82 of the winding section 80. Note that this operation may be performed manually.

When conveyance of the photographic paper 16 is started in step 204, it is determined in step 206 whether or not a page splice mark has been detected, and if an affirmative determination is made, a predetermined amount of photographic paper 16 is transferred to the bus in step 212. After that, the process moves to step 214.

If a negative determination is made in step 206, step 21
2 and proceeds to step 214.

In step 214, it is determined whether a cut mark, that is, a mark attached to every 1601 frames of photographic paper, has been detected. If no cut mark is detected, the process moves to step 206 and the above process is repeated. Also,
If an affirmative determination is made in step 214, step 21
The frame information is read from the punched hole 74 read in step 6, and then the process moves to step 218, where it is determined whether the image requires printing. This is determined by reading punched holes that do not require printing, since there is no need for printing on failed image frames or control negatives that have been printed.

If it is determined in step 218 that printing is necessary, the process proceeds to step 220, where printing is performed, and then the process proceeds to step 222, where it is determined whether printing has been completed on all photographic papers 16. . Here, in the case of a negative determination, the process moves to step 206, and in the case of an affirmative determination, this print control ends.

In this embodiment, the frame information is stored in the cutting section 1 of the photographic paper 16.
Although the punch hole 14 is punched at 6A, a bar code may be attached and read optically. Further, if the photographic paper 16 is a photographic paper with edges, the above-mentioned barcode or the like may be imprinted on the edge portion of the surface of the photographic paper. This type of memorization is done in symbols and does not require a large amount of space.
It can be done easily. Then, at the time of verification, this symbol can be read again and printed in a relatively large space on the back side of the photographic paper in characters readable by the customer without having to consider preventing latent image destruction.

〔Effect of the invention〕

As explained above, the frame information storage method according to the present invention has the excellent effect that frame information of a photographic film can be appropriately stored in image frames printed on photographic paper.
