Description

Description: FIELD OF THE INVENTION The present invention relates to a photographic reprinting apparatus for reprinting a 35mm negative film that has been reordered in accordance with the reordering, and more particularly, to printing a frame number on a bar. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reprinting apparatus which performs reprinting using a frame code, for a film having a code-displayed frame code.

BACKGROUND AND OBJECTS OF THE INVENTION Many 35 mm films currently on the market have a DX code on one end. The DX code is a latent image of information such as film manufacturer and sensitivity in the form of a bar code, and is visualized by development. On the other hand, in recent years, proposals have been made to provide a new barcode on the film end face.

This is also called a frame code or a film number code.For each frame number, a barcode indicating the frame number is provided as a latent image on the film end surface opposite to the DX code and visualized by development. It is to let.

Conventionally, reprinting of photographs has had many problems.

That is, the film that has been subjected to the development processing is cut into a short length of about 6 frames (hereinafter referred to as a film piece) and lacks in processing properties. In addition, not only the total number of prints but also a screen of a desired frame number is desired. It was required to print the number of sheets, and it was extremely difficult to automatically perform such processing.

The present invention provides a reprinting method in which a code reader for reading a frame code is provided in a printer or a reception machine to automate the reprinting process, thereby saving labor and performing the reburning process at a correct frame position. The purpose is to do.

SUMMARY OF THE INVENTION The object of the present invention is to read a frame code on a negative film for displaying a frame number as a bar code in a photo reprinting method in which a negative film having a plurality of screens is transported to an exposure stage to create a reprint print. And a screen for detecting the position of the frame code on the negative film, detecting the position of the screen on the negative film or the position of the notch on the negative film, and performing the re-burning previously input. The position of the screen or the position of the notch within a predetermined distance from the position of the frame code matching the frame number information on the negative film is determined, and the position of the screen or the position of the notch is printed. Perform printing as a reference position on the negative film corresponding to the exposure stage when performing, the position of the screen within the predetermined distance and the If there is no notch position, the position of the frame code that matches the frame number information of the screen to be reprinted is shifted from the position of the screen on the negative film to which the exposure stage is transported prior to the position on the negative film. This is achieved by a photographic reprinting method, wherein printing is performed by using a position on the negative film separated by a predetermined distance as a reference position on the negative film when performing printing corresponding to the exposure stage.

Embodiment 1 In the first embodiment, a code detector for reading a frame code is provided in a printer, and a reprinting apparatus for printing a screen of a desired frame number for a reordered film piece will be described. .

Fig. 1 shows the negative carrier part of the printer.
Reference numeral 1 denotes a negative carrier, 2 denotes an exposure stage, and a screen detection unit 3, a frame code and DX code code detector 4, and a notch detector 5 are provided toward the upstream side in the transport direction.
6a and 6b are drive rollers for transporting the film pieces.

Here, the film piece F to be printed is, for example, a third piece.
The shape shown in the figure, F1 is the screen (frame), F2 is DX
The code, F3, is a frame code, and F4 is a notch.

FIG. 2 is a flowchart showing a reordering photoprinting process of a film piece by the printer whose main part is shown in FIG.

First, reorder information including a frame number and the number of prints is automatically input by a keyboard or a mark sheet.
Next, when the film piece is set on the negative carrier 1, the film piece is transported by the drive rollers 6a and 6b and the like, and the screen detection by the screen detection unit 3 and the notch detection by the notch detector 5 are performed. Then code detector 4
Reading of the frame code. Here, it is checked whether or not it matches the already entered order information,
If they match, a check is made as to whether there is a notch or screen information at an adjacent position corresponding to the frame code.

If there is notch information, positioning information is calculated based on the notch information. When there is screen information, positioning information is calculated based on the screen information.

When there is no notch or screen information at the position corresponding to the frame code, the positioning information is calculated based on the fixed length information from the previous frame or the manual information of the operator.

The screen positioning of the order frame is performed based on the calculated positioning information, and the printing of the number of prints already input is performed based on the printing information set by the keyboard or the automatic determination. By repeating the above, the printing process for all the ordered frames in the film piece is completed.

Here, the accurate positioning of the screen corresponding to the reorder information will be described with reference to FIG. FIG. 4 illustrates a case where the film piece F shown in FIG. 3 is set on the negative carrier 1 shown in FIG. In FIG. 3, A and B indicate order frames, and frame number position information buffer memory FBF is used for positioning this screen.
And three buffer memories, a notch information buffer memory NBF and a screen information buffer memory KBF.

First, when the film piece F shown in FIG. 3 starts to be conveyed on the negative carrier 1 shown in FIG. 1, (a) the screen detection unit 3 detects the screen center based on the left and right edges of the screen and the front and rear screen information while performing screen detection. Position in KB
Register with F and go.

(B) The notch detector 5 registers the notch center position in the NBF while performing notch detection.

(C) While detecting the frame code F3 by the code detector 4, if the frame number matches the already-input frame number information, the FB is determined using the frame number numeric position corresponding to the frame code.
Register with F. Since just detected the frame code of order frame B in FIG. 4, it registers the f ₂ to FBF.

The detection is performed in this manner, and while the data is registered in a predetermined buffer, the first contents (f ₁ , n ₁ , k ₁ ) of each buffer are stored.
Is composed of a counter which decreases sequentially as the film piece F is conveyed, so that each buffer changes its contents in a manner completely synchronized with the conveyance state of the film piece F.

The case where the order frame A is stopped at the optical axis will now be described.

The first counters f ₁ , n ₁ , and k _{1 of} each buffer sequentially decrease with the film transport, and when any one of the three becomes zero for the first time, the three are within the fixed distance. If they exist, the three persons are compared and compared. In comparison and comparison, if there is a notch, give priority to it.
This is determined as the stop positioning amount of the order frame A. In the case of order frame A, the information of the three parties is compared and collated together, but there are naturally only two cases,
For example, in the case of NBF and KBF, there is no frame number information, so there is no need to stop. In the case of order frame B, FBF and KBF
In some cases, the user stops only with the screen information.

Although the embodiment described in detail above is an example including both the notch detector and the screen detection unit, either one of them may be used. In addition, in consideration of the danger when neither the screen information nor the notch information is actually detected, if the stop positioning of the frame is performed by further taking the fixed-length distance information from the frame stop point into consideration with such information, A more accurate screen stop can be performed.

The embodiment described above is an embodiment in which a printer is provided with a frame code detector.When a large number of reorder prints are to be performed, a reception device for performing reorder information input processing and a general printer are used. It is preferable that a recording medium, such as a cassette tape, which has been input processed by the receiving machine, and a roll film to which a film piece is connected be attached to the printer to perform reorder processing.

In this case, the reception machine includes a screen detection unit, a notch detector,
A code detector for a frame code and a DX code is provided along the negative carrier, and a flowchart of the reorder information input processing of the accepting machine of the second embodiment shown in FIG. 5 will be described.

First, after the reordering information of the frame number and the number of prints is input to the receiving machine by automatic input such as reading of a keyboard or a mark sheet or the like, the reordered film piece is set in the transport unit of the receiving machine.

The set film piece is conveyed and passes through the screen detection unit and the notch detection unit, and the screen detection and the notch detection are performed.

Subsequently, the frame number represented by the bar code is read by the frame code detecting unit, and it is immediately checked whether or not the read frame code matches the input order information. If there is a matching frame number, it is checked whether there is a notch or screen information at a position corresponding to the frame code.

If there is notch information, the notch information is converted into distance information. If there is screen information, the screen information is converted into distance information, and if necessary, notch punching is performed.

If there is no notch or screen information at the position corresponding to the frame code, the fixed-length information from the previous screen or the manual information by the operator is converted into distance information. At this time, notch perforation may be performed.

The frame number and the distance information thus obtained are recorded together with the number of prints on a recording medium such as a cassette tape.

When the search for all the frames of the film piece is completed in this way, the film piece is sent from the receiving machine to the next step, such as an edge splicer, and the film piece is connected in a roll shape.

In this way, the frame number information and the number of prints for which a large number of reprints are desired are input to the recording medium together with the distance information of the frame number.

Next, the cassette tape and the roll film to which the film pieces are input are connected to the printer and the roll film is set in the printer for reprinting. However, the printer does not need to have a frame code detection unit.

FIG. 6 shows a flowchart of a re-order photo printing process using such a printer.

First, when the cassette tape and the roll film are set, the distance information from the piece reference position is set from the cassette tape.

Subsequently, when the film is transported, the screen detection and the notch detection are performed. Next, it is checked whether the previously set distance information has reached a predetermined position. When a predetermined position is reached, distance information for positioning is calculated based on the notch or screen information in the vicinity thereof, and screen positioning is performed based on the notch or the calculation result. At this point, the burning information is set by input from the keyboard or by automatic determination, and burning is performed based on the number data inputted to the cassette tape.

In this way, when the order printing for one piece in the roll film is completed, the printing for the next next film piece is performed, and the process is repeated to complete the photo printing for reordering all the roll films.

Also in this embodiment, accurate distance information is set in the reception device in the same manner as in the first embodiment.

[Effects of the Invention] According to the present invention, when re-burning a negative film, it is possible to print an image of the negative film that correctly corresponds to the previously input frame number information of the re-burning.
