Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a photographic film package capable of recording various information at various times.

[Conventional technology]

Conventionally, in order to improve the image quality of prints, various types of information have been collected using optical, magnetic, or electrical means, such as shooting information (whether or not a strobe is used, color temperature, LV value, shooting distance, and lens focal length). , subject contrast, shooting date and time, shooting location, etc.), film information (film type, film manufacturing date, printing conditions, etc.), laboratory information (
The laboratory name, development date, printing conditions for simultaneous printing, etc.) have been input into the photographic film.

Regarding this information input method, for example, JP-A-62-5
It is described in Japanese Patent No. 0743, Japanese Patent No. 62-209430, US Pat. No. 4,864,332, and others.

[Problem to be solved by the invention]

However, conventional information input methods have used only one of optical, magnetic, or electrical means.

For this reason, it has been extremely difficult with conventional information input methods to easily and reliably input the aforementioned various information at times such as film production, photographing, development, printing, and reprinting.

This problem is particularly serious in films with small screen sizes such as 110 format and half size format.

The present invention has been made in view of this point, and it is an object of the present invention to provide a photographic film package that allows input of various information at various times as described above.

[Means to solve the problem]

To achieve this objective, the present invention provides a cartridge and
A photographic film or cartridge in a photographic film package comprising a spool rotatably supported around an axis inside the cartridge and a photographic film wound around the spool in the form of a roll is improved, and the photographic film or cartridge is an optical film. means, electrical means or magnetic means. That is, as an optical means, the width of the photographic film is 20 mm or more and 35 mm or less, and the area of one frame of the image exposure part of the photographic film is 200 mm.
The optical information recording portion is formed on the photographic film so that the area thereof is 30% or more of the area of one frame of the image exposure portion. Furthermore, in addition to this optical means, the photographic film or cartridge is provided with at least one of electrical storage means and magnetic storage means.

In a preferred embodiment, the optical information recording section is provided outside the image exposure section in the width direction of the photographic film.

In a preferred embodiment, a semiconductor element is used as the electrical storage means provided in the cartridge.

Furthermore, in another preferred embodiment, the photographic film or cartridge is provided with magnetic storage means.

In order to maintain the image quality of the print, the area of one frame of the image exposure section needs to be 200 mm' or more. In addition, if the area exceeds 500 mm + n2, the area of the part that can be used for recording information as an optical means decreases, so the area of one frame of the image exposure section is 200 mm2 or more and 500 m2 or more.
It is preferable that it is less than m2.

A more preferable embodiment has a film width of 26 to 32 mm,
The area of one frame of image exposure part is 350mm' to 450m [1
12.

With current photographic films, photographic film manufacturing information is often entered as a barcode on the outside of either the left or right perforation. If you try to input various information in addition to this manufacturing information using the barcode method, there is not enough input space if you input one row on each side of the photographic film, so at least two rows of input space on one side are required. .

Therefore, it is necessary to increase the ratio of the area of the optical information recordable portion to the area of one frame of the image exposure section from the current 11% to 30% or more. Even if a recording method other than barcodes is adopted, the information density is not much different and the same area ratio is required.

On the other hand, since it is desirable that the area of the image exposure section be large, a preferable upper limit of the ratio of the optical information recordable area to the area of one frame of the image exposure section is determined in consideration of this point.

The upper limit of this ratio is preferably 60%, more preferably 50%.

Alternatively, for example, by removing or reducing the perforations, it is also possible to increase the area of the optical information recordable portion without reducing the area of the image exposure portion.

In this case, instead of regular perforations, one perforation or notch is used for positioning the screen.
It is preferable to provide one or two per frame. 2
When providing two, they may be provided on one side or on both sides with the screen in between.

In this specification, the ratio of the area of the optical information recordable portion to the area of one frame of the image exposure portion is defined as follows. As shown in Figure 1, the horizontal length of one image exposure section is a, the vertical length is b, and the width of the photographic film is C.
Then, the film area A for -frames is A=aXc, the area B of the image exposure part is B=axb, and the area C of the optical information recordable part is (,=-A-B=ax (c-b ).Therefore, the area ratio of the optical information recordable portion is C/A.
= (A-B)/A-(c-b)/c.

If there are perforations, the area C is the area of the half-orage hole removed.

It is not necessarily necessary to utilize all of the optical information recordable portions. All you have to do is record the necessary information in the necessary parts depending on the purpose.

In the photographic film of the photographic film package according to the present invention, the optical information recordable portion is preferably formed outside the image exposure area in the width direction of the photographic film. This is because if an optical information recordable portion is formed between the image exposure portions, the total length of the photographic film increases, which is disadvantageous in making the camera thinner.

Preferably, the character information is input in the form of characters or barcodes.

It is preferable to input various information input at the time of film production or photographing using optical means that utilizes the photosensitivity of photographic film from the viewpoints of simplifying the manufacturing process, downsizing the camera, and reducing costs. However, it is better to input and read information to confirm the usage status of the film (unused, used, number of shots, etc.) using magnetic or electrical means, as there is no need to develop the film. preferable.

Further, it is preferable to input various information in the laboratory using magnetic means or electric means, since this allows information to be input even after the film is developed.

Generally, it is suitable to input information using optical means during photographing and using magnetic means after development. For example, in order to magnetically input information from a camera onto photographic film during shooting, it is necessary to maintain a constant relative speed between the film and the magnetic head, and in order to electrically store information in a semiconductor element, it is necessary to maintain a constant relative speed between the film and the magnetic head. , circuits and contacts with semiconductor elements are required for this purpose, which requires the camera to be equipped with a complex mechanism. For this reason, optical means that utilizes the photosensitivity of photographic film are superior to information manpower during photographing due to their reliability and simplicity.

On the other hand, once the photographic film has been developed, it is no longer possible to use optical means that utilize the photosensitivity of the photographic film, so it is necessary to use magnetic or electrical means.

The semiconductor element used as electrical storage means is EEPRO.
M etc. are preferred. Preferably, the semiconductor element is attached to the cartridge, or the cartridge and semiconductor element may be separated and loaded into the camera separately. Furthermore, an IC card containing a microcomputer and an EEPROM can also be used as the electrical storage means.

As a magnetic self-memory means, US Pat. No. 4,302,523
Transparent magnetic bases disclosed in Japanese Patent No. 3782947 and Japanese Patent No. 4279945 are preferred. The advantages of this transparent magnetic base are that information regarding the film screen can be input at a position adjacent to the film screen, and that the optical information recording section can also be used as a magnetic information recording section. The magnetic information recording layer can also be formed only outside the image-exposed area.

In this case, the magnetic information recording layer may be opaque.

When the cartridge is provided with magnetic information recording means, information regarding the DX code and the usage status of the film can be input and output to this magnetic means. It is preferable that the information regarding the film usage status input into the cartridge can be checked without removing the film from the cartridge. Methods for providing magnetic recording means in the cartridge include attaching magnetic tape to the cartridge, molding the cartridge from a polymer mixed and dispersed with a magnetic material to give the cartridge a magnetic recording function, and using ink containing a magnetic material dispersed therein. There are methods for printing cartridges, etc.

In order to prevent the information input by optical means from disappearing due to so-called "light fog", the cartridge is preferably of a light-tight type (for example, the one described in Utility Model Application No. 1-17253).

〔Example〕

FIGS. 2 and 3 show an embodiment of the photographic film package according to the present invention. As shown in Figure 2,
The base 2 of the photographic film 1 has a thickness of 122 μm. Base 2 is cellulose triacetate paste, and the back side is 0.1g/rr? Magnetic material (γ-Fe2
0+)3 is applied (see Japanese Patent Publication No. 57-6576).

The front side of base 2 has a coating silver amount of approximately 7 g/m and has a sensitivity of 4.
A photosensitive layer 4 for a color negative film of No. 00 is formed (see Japanese Unexamined Patent Publication No. 63-236035).

FIG. 3 shows a state in which a photographic film l (film width 30 m) is stored in the photographic film package 5. The photographic film package 5 includes a spool 6 and a cartridge body 7.
The spool 6 has one end 6a supported rotatably around an axis inside the cartridge body 7, and the other end 6b.
protrudes from the cartridge body 7 to the outside, and is supported from the outside of the cartridge body 7 so that the spool 6 can be rotated. The photographic film 1 is stored in a rolled state on a spool 6, and the cartridge body 7 has an opening 8 for pulling out the photographic film 1. Photographic film 1 has an image exposure area (area 432
mm') 9, an optical information input section 10, a section 11 that serves as both optical and magnetic information input, and perforations 1 for positioning frames of the photographic film 1.
It has 2. The optical information input section 10 is a photographic film 1
This is an optical storage means that utilizes the photosensitivity of .

Inputting various information using the photographic film l housed in the photographic film package 5 as described above and creating prints using the information are performed, for example, as follows.

(2) Information such as the DX code and film manufacturing date is input into the optical/magnetic information input section 11 during film processing. The input may be text or a barcode may be used.

(2) Using the LED attached to the camera, input the date of photographing, presence or absence of a strobe, trimming information for pseudo zoom, etc. in the form of a bar code to the optical information input section 10.

■ Automatically set printing conditions to correct for changes in film over time based on data such as film manufacturing date, shooting date, development date, etc. Setting is performed automatically according to a program pre-installed in the auto printer.

This makes it possible to minimize deterioration in print quality due to changes in the film over time.

■ When using a strobe, corrections are automatically made to add yellow to the print according to the program built into the auto printer. As a result, color correction, which previously had to be done manually, can now be done automatically, reducing the variation in colors in photos taken using strobe lights.

■ Cropping is automatically performed on the auto printer when printing according to the pseudo zoom information.

Even after cropping, the shooting date is printed in the bottom corner of the print screen. In this way, it is possible to create a pseudo-zoom print without any manual effort, and it is also possible to print the date on the pseudo-zoom print.

(2) In the laboratory, the print conditions predicted in (2) and the corrected print conditions for each frame are magnetically input to the optical/magnetic information input section 11.

This makes it possible to reduce changes in color tone during simultaneous printing or reprinting.

(2) The number of prints for reprinting, trimming conditions, etc. are magnetically input into the optical/magnetic information input section 11 at the store. This improves the efficiency of reprinting in the lab and makes it easier to reflect the photographer's intentions in the prints.

As is clear from the above, by using both optical means and magnetic means as in this example, it is possible to input various information not only at the time of photography but also after development, which improves the image quality of the print. can be improved.

Next, another embodiment of the photographic film package according to the present invention is shown in FIG. The package 2o includes a cartridge body 21,
It consists of a cartridge body 21, a flexible wall 22 joined at one end thereof, and a spool 23 rotatably supported inside the cartridge body 21. The flexible wall portion 22 has a pair of protrusions 2 at both ends that engage with a mechanism on the camera side.
4a and 24b are formed. The photographic film 25 is housed inside the cartridge body 21 in a tightly wound roll shape around a spool 23. The photographic film 25 used is the same as the photographic film 1 shown in FIG. 3 (see Japanese Patent Application No. 63-57785).

When the package 20 is loaded into the camera, a mechanism (not shown) on the camera side engages with the projections 24a, 24b, and the projections 24a, 24b engage with the projections 24a, 24b.
Push up 24b. Since the cartridge body 21 is fixedly loaded inside the camera, the protrusions 24a and 24b
4, the flexible wall portion 22 is bent upward to form a film outlet 26. As shown in FIG.

Thereafter, by rotating the spool 23 in the film feeding direction (counterclockwise in FIG. 4), the photographic film 2
5 is tightly wound around the spool 23, the photographic film 25 is fed out from the film outlet 26 and guided to the film exposure position within the camera.

A magnetic tape 27 is attached to the outside of the wall of the cartridge body 21 of the package 20 as a magnetic storage means. As the magnetic tape 27, for example, a commercially available magnetic tape for audio can be used.

Information regarding film sensitivity is inputted into the magnetic tape 27 in advance, and when the package 20 is loaded, an appropriate input/output mechanism (not shown) on the camera side reads out the information. Furthermore, when the package 20 is taken out of the camera, information on the number of used films is transferred to the magnetic tape 2 by the camera's input/output mechanism.
7 is input. If you reload the cartridge into the camera with the information on the number of film used, you can prevent the used film from being fed, and if the photographic film is halfway used, the unshot frames will be exposed to the camera. The photographic film can be automatically advanced until the position is reached.

As a magnetic storage means, EE is used instead of the magnetic tape 27.
PROM can also be used (Japanese Patent Application Laid-Open No. 116-1988)
(See Publication No. 932). The DX code, film usage status, shooting location, etc. are input into this EEPROM. Furthermore, if information such as printing conditions is input into the EEPROM in the laboratory, the information can be used later when reprinting. Further, the photographer's number of reprints, trimming conditions, etc. can also be input into this EEFROM.

Furthermore, in the above embodiments, a photographic film in which cellulose triacetate paste is used as the film base containing a magnetic substance may be used. In this case, the printing conditions for each frame are also input into the EEPROM in the laboratory.

〔Effect of the invention〕

By using the photographic film cartridge according to the present invention, which uses optical storage means as well as magnetic storage means or electric storage means, it becomes possible to input various information easily and reliably at various times.
