Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method of handling photographic film.

[Conventional technology]

Due to pseudo-zoom printing, etc., I
A system has been proposed in which information such as print magnification is recorded on C or a magnetic recording medium, and this information is used to print (Japanese Patent Laid-Open Nos. 62-103625 and 62-20).
No. 8028, JP-A No. 1-279231, JP-A No. 1-2
No. 89948, etc.). In this way, for films that also record information such as print magnification, if the film is returned after simultaneous printing as a film piece cut every 4 to 6 frames, as is currently the case, the above information may be separated. Therefore, information such as print magnification cannot be used effectively when making additional prints.

For this reason, a film storage cartridge has also been proposed in which the developed film is wound and stored as it is without cutting it into individual pieces (Japanese Patent Laid-Open No. 1-279250, Japanese Patent Application No. 2-9519).

[Problem to be solved by the invention]

By the way, in the case of film whose format is determined on the premise of recording pseudo-zoom information, subject position information, etc. during shooting (hereinafter referred to as new type film),
It is desirable from the viewpoint of reducing industrial waste to use the same cartridge for photographing and for returning, and a method for realizing this has also been proposed (Japanese Patent Application No. 2-238036).

However, there remains the question of how to handle a film whose format was originally determined in a format (without considering the recording of photographic information, etc.), such as the conventional 135 format (hereinafter referred to as 1-day type film). In particular, when new formers and gutter become popular, both old and new types will be brought into photo labs, and the ability to efficiently process them becomes an important issue.

The present invention is intended to solve the above-mentioned problems, and is a photographic film that enables conventional old type films and new type films with newly developed information recording formats to be handled in the same way. The purpose is to provide a method for handling.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a method for handling photographic film of the type in which photographed film is wound into a cartridge, in which films having different cartridge nozzle shapes and/or film formats are processed after being processed. The film is wound and stored in an empty winding cartridge of approximately the same shape, and identification information is recorded on this winding cartridge so that the type of film that has been wound and stored can be identified without having to pull out the film. In subsequent steps, the identification information is read to identify the type of film in the cartridge, and the processing sequence is switched for each film type.

Further, another invention provides the winding cartridge of the above invention,
It is possible to store shooting information other than film type identification information, and if shooting information, etc. is recorded on the original shot film, information necessary for later processes is stored from among these shooting information, etc. However, if shooting information, etc. is not recorded on the original photographed film, information indicating this is stored, and in subsequent processes such as printing, necessary information is additionally stored, and the information is stored in the previous process. The stored information is read and the processing sequence is switched.

[Effect]

Films having different cartridge shapes and/or film formats, for example, an old type film and a new type film, are wound up and stored in a winding cartridge having a film cue function after being developed. Then, film identification information for identifying both the old and new types of film is stored in the IC memory of the winding cartridge. For printing exposure after development processing, film identification information is read from the IC memory, and each type of film processing sequence is selected based on this film identification information, whereby both the old and new films are printed and exposed.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

As shown in FIG. 2, the film cartridges used in this embodiment include a well-known current type 10 that is currently widely used, and a new type 11 that is capable of recording shooting information, etc. . Both old and new types of film cartridges 10 and 11 have the same basic configuration, including a cartridge body 10a, lla, a spool 10b, llb rotatably attached to the cartridge body 10a, lla, and a spool 10b.

It is composed of photographic films 12 and 13 whose one end is fixed to 11b and wound and stored.

The major differences between the old and new types of film cartridges 10 and 110 are that the new type cartridge 11 has a magnetic recording layer on the film base, and can record shooting information, print information, etc. on the film, and The two points are that it has a function.

As shown in FIG. 3, a new type of cartridge body 11
A is formed into a square box shape by joining half-split members made of synthetic resin, and has an opening 16 for the film 13 and a spool l.
A hole 18 is provided for exposing the engaging end portion 17 of the lb to the outside. A light-shielding telescope 19 is attached to the film entrance/exit 16. Further, the film storage chamber 20 of the cartridge body 11a is formed with an inner diameter that is approximately the same size as the maximum winding diameter when the film 13 is wound onto the spool llb. As a result, when the spool llb is rotated in the film feeding direction opposite to the film winding direction, the leading edge of the film 13 is guided by the inner wall surface of the film storage chamber 20 and the film can be moved to the outside through the film opening 16. . In this embodiment, the cartridge main body 11a is formed into a rectangular box shape to improve stability when stacking these cartridges, but this shape may also be cylindrical as in the conventional case. .

The film leading end 13a is roundly cut to reduce film feeding resistance when the film is brought to the beginning and when the film is guided to the winding shaft on the camera side. This tip 13a has a perforation 21.
A sprocket on the camera side engages with this to feed the film leading end 13a to the winding shaft inside the camera after the film has been positioned. Further, the perforation 21 is engaged with a claw on the winding shaft of the camera, so that the film is reliably wound onto the winding shaft. In addition, the image recording section 13
In b, a positioning perforation 22 is attached to each frame 23.
This perforated gin 2 is formed one by one.
2 is detected mechanically or optically, each frame 23 of the film is sequentially set in the exposure frame of the camera.

As shown in Fig. 2, both old and new types of cartridges 10
．． After the eleven films 32a and 32b are developed by the film processor 25, they are wound up and stored in the winding cartridge 30.

The old and new types of films 32a and 32b may be developed separately for each type, or both types may be developed in a mixed state. In this case, a cartridge cover 26 is attached to the old type cartridge 10 so that it can be handled in the same way as the new type cartridge 11. Then, the new and old cartridge types are detected based on whether the leading edge of the film is exposed or not, and in the case of a new type cartridge, the spool is rotated in the film feeding direction to locate the beginning of the film. In addition, in the case of old type film,
The leading end of the film is nipped and the film is pulled out and developed. After the development is completed, the film is wound up and stored in the winding cartridge 30. At this time, depending on the type of the stored film (new or old), if it is a new type film, the film information, shooting information, etc. recorded in the magnetic recording layer are stored in the IC memory 31.
In the case of an old type film, default information indicating that it is an old type film is recorded in the IC memory 31. Note that instead of recording the default information, film type identification information indicating the respective types of film may be recorded on the cartridge 30 containing both old and new types of film.

The winding cartridge 30 has basically the same shape and structure as the new type cartridge 11.

The difference from the new type cartridge 11 is that it has an IC memory 31 for recording film information, shooting information, print information, etc. (see Figure 4), and that it has an IC memory 31 for recording film information, shooting information, print information, etc. A film leader 33 for taking out and storing the film is fixed to the spool 35 while protruding from the film opening 34. The IC memory 31 is embedded in the end surface of the spool 35 opposite to the end surface where the engaging portion is exposed.

As shown in FIG. 2, after the development process, both the old and new types of film 32a or 32b are joined to the film leader 33 of the take-up cartridge 30 via a splice tape 36 or the like, and are inserted into the cartridge 30 by rotation of the spool rotation shaft 37. It is rolled up and stored. This wound and stored film 32a or 32b is sent to the printer processor 38.
The printing process is performed.

As shown in FIG. 1, a developed film 32a or 32b is set in a film setting section 40 of a printer processor while being wound around a winding cartridge 30. As shown in FIG. As shown in FIG. 5, the film setting section 40 includes a spool rotation shaft 41, a motor 42 that rotates the spool rotation shaft 41 in forward and reverse directions, and a shift section 4 that shifts the spool rotation shaft 41 in the axial direction.
3 and an IC memory read/write plug 44.

The IC memory read/write plug 44 includes a contact pin 45 arranged at a position corresponding to the contact point 31a of the IC memory 31. This plug 44 is connected to a controller 50 as shown in FIG.

The controller 50 is composed of a well-known microcomputer, and includes an I10 interface unit 51 and a C
It includes a PU 52, a ROM 53, a RAM 54, a keyboard 55, and a display 56. The I10 interface unit 51 is connected to the IC memory 31 via the plug 44, and reads various information written in the IC memory 31, and also writes print information etc. after printing into the IC memory 31. In addition, the controller 50 sequentially controls each part of the printer processor based on a program in a built-in ROM 53.

At this time, the processing sequence is changed for each type of film, new type film and old type film, based on the film identification information recorded in the IC memory 31.

A well-known light source section 61 is arranged below the film carrier 60. The light source section 61 includes a light source 62, a filter adjustment section 63 that adjusts the intensity of the three color components of the printing light from the light source 62, and a mixing box 67 that diffuses and makes uniform the printing light that has passed through the filters 64 to 66. It consists of Further, a zoom lens 70 is arranged above the film carrier 60, and a zoom lens 70 is arranged above the film carrier 60.
The image of the frame set to be printed is formed on the photosensitive emulsion surface of the color paper 71. The zoom lens 70 is driven by a driver 72. The driver 72 sets the print magnification of the zoom lens 70 according to the print magnification signal from the controller 50. Also, zoom lens 7
A shutter 73 is arranged between the color paper 71 and the color paper 71, and is controlled by a shutter drive section 74.

Further, a paper mask 75 is placed on the paper 71 at the print position, as is well known.

Further, a scanner 76 is arranged diagonally above the film carrier 60. As is well known, the scanner 76 performs three-color separation photometry on each point of the frame to be printed. This photometric data is sent to the characteristic value calculation section 77, where it is exposed!
Various characteristic values necessary for calculation are extracted. Exposure calculation unit 7
8 calculates the exposure amount of the frame to be printed using a well-known exposure calculation formula based on various characteristic values. The controller 50 is
As is well known, the filter set position is determined from the exposure amount, and the filter adjustment section 63 is controlled so as to be at this position.

A pair of film feed rollers 80 is arranged on the film exit side of the film carrier 60 and feeds the printed film to a film reservoir 81. The film reservoir 81 stores the film in a loop shape. Further, a pair of paper feed rollers 83 is arranged on the paper exit side of the paper mask 75, and feeds the printed and exposed paper 71 to a paper processor section 84. After developing the paper 71, the paper processor section 84 cuts the paper 71 frame by frame and discharges each print photograph to a print accumulating section 85.

When the film set in the film setting section 40 is a new type of film 32a, printing is performed using the following processing sequence. First, the film 32a that has been indexed by the film center section 40 is sent to the film carrier 60 by a pair of film feed rollers 86. During this film feeding, film information recorded on the magnetic recording layer of the film 32a by the magnetic reading section 87,
Photographing information, print instruction information, etc. are read, and these various pieces of information are stored in the RAM 54. Then, by detecting the perforation 22 for frame feeding by the perforation sensor 8, by feeding the film a fixed amount after this detection,
Each frame 23 is set in a mask opening in the film carrier 60.

Thereafter, the scanner 76 operates to photometer the frame to be printed. Then, from this photometric data, the characteristic value calculation unit 7
7 and an exposure amount calculation section 78 calculate the exposure amount. Note that when performing exposure correction based on the photographic information, the controller 50 creates exposure correction data based on the photographic information and sends it to the exposure calculation unit 78. Exposure correction based on this photographic information is explained in detail in, for example, Japanese Patent Application No. 2-233573. Furthermore, if pseudo zoom length information is recorded, the print magnification of the zoom lens 70 is set based on this information.

Thereafter, the filter adjustment section 63 is driven to adjust the quality of the printing light, and then the shutter 73 is opened for a predetermined period of time to print and expose the frame to be printed. After the printing exposure, the paper 71 and film 32a are moved frame by frame to print the next frame.

In the case of the old type film 32b, an edge sensor 89 detects an edge that is a boundary between a frame and a margin between each frame, and each frame is set in the mask opening of the film carrier 60 based on this detection signal. Unlike the new type film 32a, the old type film 32b does not record film information or photographing information, so the magnetic reading section 87 does not operate, and the subsequent printing process is the same as that for the new type film. , the explanation is omitted.

After printing both the new and old types, the film 32a or 32b stored in the film reservoir 81 is wound up and stored in the cartridge 30 by reversing the spool rotation shaft 41. Then, at the time of winding and storing or immediately after winding and storing, the old type film 32b is stored in the IC memory 31.
In this case, exposure conditions such as density correction and color correction during simultaneous printing are recorded in correspondence with the frame number. Also,
If the new type film 32a is used and various information is transferred to the IC memory 31 during film development, exposure conditions during printing are additionally recorded. Furthermore, if various information is not transferred to the IC memory 31 during film development, various information recorded on the magnetic recording layer of the film is also recorded in addition to the exposure conditions during printing.

After recording data such as printer conditions, the cartridge 30 is taken out from the film setting section 40, a new cartridge 30 is set in the film setting section 40, and the same process is repeated thereafter. A flowchart of this printing process is shown in FIG.

If the result of simultaneous printing is poor and it is necessary to reprint, this cartridge 30 is transferred to the film setting section 40.
Set to . Then, the user operates the keyboard 55 to instruct reprinting.

In this reprint, the controller 50 is an IC
Film information, photographing information, print information, etc. read out from the memory 31 are collectively displayed on a display 56 for each frame. In this state, by operating the keyboard 55, the printing conditions for reprinting are determined, and by inputting these by specifying the frame number, the controller 55
The designation of the frame to be reprinted and its correction conditions are recorded in the RAM 54 of No. 0. Then, based on this reprint information, printing exposure is performed in the same way as simultaneous printing. After reprinting is completed, the reprint information is input to each frame number.
It is recorded in the C memory 31.

When reordering, the cartridge containing the developed film is set in the reception processing machine, and data specifying the frames for reordered printing and the number of copies to be printed are input into its IC memory. In this case as well, a plug having the same structure as the film setting section is provided, and data is read and written from the IC memory through this plug.

In addition, in the above example, the new type film and the current 13
Although the description has been made assuming a combination with type 5 film, the present invention is not limited to this, and can be applied to a winding cartridge of the same shape even in other combinations, such as mixed processing of type 126 film and type 135 film. A similar process can be performed by winding it up.

[Effects of the Invention] 4. As explained above, in the present invention, the shape of the cartridge and/or the film former 0. Films with different shapes and sizes are pulled out from the cartridge, developed, and wound into a take-up cartridge.
In printing processing after film development, it can be handled in the same way, and these processing can be performed smoothly. Moreover, it becomes possible to process multiple types of films with the same printer, and equipment efficiency and processing efficiency can be improved.

Moreover, even if the old type film is used, the printing conditions for simultaneous printing and the number of sheets specified when reordering can be recorded on a recording medium such as an IC memory, just like the new type film. Services such as pseudo-zooming printing similar to film and finishing reordering in the same way as simultaneous printing will become possible.
