Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for developing a disc film, and more specifically, to a novel photographic method that allows a photographed image to be visually viewed by printing or pure immediately after photographing. It is used in processing systems and does not require darkroom equipment.
It can be installed in small spaces such as camera stores, DPE distributors, film retail stores, etc., and can perform processing with good photographic performance through simple operations. The present invention relates to a developing method for disc film that can be operated and used at home.

[Conventional technology]

Everyone has the desire to see the photos as soon as they are taken, and what has made this possible is the so-called instant photography, which has recently become a hot topic, including those made by the famous Polaroid company in the United States. There are electronic types that do not use photographic film but use magnetic recording media (for example, Sony's electronic still camera).

However, the former has a high unit price per sheet and is not suitable for producing multiple prints, while the latter currently does not provide sufficient satisfaction in terms of photographic performance such as sensitivity and resolution. Moreover, the equipment is expensive, the equipment is larger than the disk camera discussed here, and it is not possible to produce hard copies with the high resolution and sharpness of silver halide photographs.

In addition, there are photo processing kits that perform development processing by injecting photo processing liquid into a magazine containing self-developing film or roll film, but the former uses a special film that is completely different from normal photographic film. The latter is intended for so-called photography enthusiasts and cannot be easily handled by ordinary people without photographic knowledge, and is not compatible with the novel photo processing system intended by the present invention.

In view of the above, the inventors of the present invention have researched other photo processing systems that satisfy the desire to view images immediately after shooting, and as a result of the present invention, the present inventors have discovered that the present invention enables printing or pure processing using disk film immediately after shooting. The purpose of the present invention is to clarify a novel photo processing system that allows photographed images to be viewed visually, but the prior art for understanding the present invention is as follows.

Disc film is provided as a film unit housed in a cartridge, and after being set in a special camera and photographed, it is collected via a distributor at a centralized photo processing facility called a laboratory, where it undergoes photo processing such as developing and printing. .

The disk film is taken out from the cartridge by a cartridge opener in a laboratory, and a large number of disk films are set in an automatic developing machine and are automatically developed while being rotated at high speed.

Regarding photographic (processing) technology using disc film,
Although many conventional roll film technologies have been repurposed,
Examples of things specific to disc film include:

There is one described in Kodak Disc Film System Overview (Photography Industry, April 1982 issue, pages 26-41).

In addition to the above, prior art for understanding the present invention is set forth in the relevant portions of the following description.

[Problem that the invention seeks to solve]

Disc film, like other amateur photography films such as 35mm roll film, is protected from light by being stored in a light-tight container (hereinafter referred to as a cartridge).
When shooting, the cartridge is attached to the dedicated camera. The dedicated camera has a cartridge installed and winds up (cue)
The shutter of the exposure window of the cartridge is opened in conjunction with
Bi shadow is possible. After photographing is completed, the shutter of the cartridge exposure window is closed in conjunction with the cartridge ejection operation, and the disc film is again protected from light within the cartridge.

As described above, the development process for such a disc film involves destroying the cartridge in a dark room, taking out the disc film, and then performing one color development, bleaching, fixing (or bleach-fixing),
The reality is that each processing step, such as water washing (or stabilization), is substantially carried out in a dark room, as in the case of roll film.

Furthermore, although conventional processing equipment has the advantage of being able to process a large number of sheets at once, disc film consumers in Japan prefer amateur photography film (mainly 3511I).
110-LeFilm), and the amount of processing processed at camera stores per day is only a few sets-0.
The number of cassettes is extremely small, and intensive processing by laboratories as described above is inevitable. In recent years, this has resulted in turning our backs on consumer needs for shortening processing (waiting) times, such as one day, several hours, or even an hour from in-store reception to delivery, which is particularly noticeable with 35-Peng roll film. ing.

On the other hand, development processing equipment that can process such a large number of sheets at once is
The treatment tank is unnecessarily large, and the replenisher tank, treatment liquid replenisher, waste liquid tank, or washing water pipes are A410, which not only makes the treatment tank unnecessarily large, but also makes the operation complicated, including darkroom operation in case of trouble. However, since a certain level of specialized knowledge is required, it is difficult to install the camera at a camera store and provide development processing services at two stores, which goes against the goal of shortening the processing (waiting) time.

35+SM roll film is water-free, has no piping, is table-sized, and allows in-store service with short processing times (within 1 hour).The response of photo processing equipment manufacturers to the trend toward minilabs is disc film or disc film. This offsets the advantages that cameras have over 35-inch roll film or cameras, such as ease of operation, ease of handling, compactness, and ease of organizing photographed film, and hinders the spread of disc film. , causing the aforementioned vicious cycle.

In recent years, as electronic devices such as videos have become popular, people are no longer satisfied with just looking at prints as before, but there is a strong desire to view them on a large screen such as a television with a large number of people, including family members.

Rapid progress in electronic devices in recent years has made it possible to electronically read out color image information from developed films, and display it on all types of displays, not just televisions. Not only that, but the ability to freely enlarge and modulate color tones has made it possible to view the films you have taken under optimal or most favorable conditions.

One of the advantages of such electronic devices is that images can be obtained immediately from the film without printing, and compared to conventional simultaneous printing systems, the development process is just as simple as the printing process is unnecessary. It will only take half. This brings us one step closer to the original desire to view pictures as soon as they are taken, but the more this happens, the stronger the demand for shorter development processing (waiting) time becomes.
There is a growing demand for in-store processing services and even in-house processing. In this case, it is clear that the processing machines currently available on the market cannot handle the problem as described above. In other words, for this purpose, it is sufficient if it is possible to process at most 1 to 2 sheets at a time, the size of the processing machine is as small as possible (for example, desk top, butaibu, etc.), and the operation is simpler than described above (i.e. (No need for one button or complicated darkroom operations).

In view of the above-mentioned points, the present researchers conducted intensive research and found 1.
SUMMARY OF THE INVENTION The general object of the invention is therefore to solve the problems described below.

A. Rapid processing: Like the case of roll film, DPE using disc film is intensively performed in a laboratory, so the finishing process can be completed as quickly as 80 days by requesting a distributor, but normally it takes more than two days. From the time of shooting, the earliest is usually the next day.

Further, in a laboratory, since a large number of disc films are automatically processed, it is practically difficult to process a specific small number of disc films particularly quickly.

In addition, labs are unevenly located, and as long as photo processing is done in the lab, it is not possible to satisfy the desire to make the photos visible immediately after taking them.Therefore, in order to satisfy this desire, it is necessary to Familiar places, such as camera stores,
It would be desirable to be able to perform photographic processing at conventional DPE distributors, film retailers, etc., and furthermore, to enable in-house processing.

B. Downsizing and simplifying the device: In order to be able to install it in a narrow space such as an ordinary camera store, conventional automatic processors require a considerable amount of installation space even if they are small. It is desirable to downsize the device.

C5 Bright Room Processing: Except for camera shops that have traditionally processed photographs, it is difficult to install dark room equipment in places that do not have it, considering the space and cost involved in adding new dark room equipment. It would be desirable to be able to perform photographic processing using a room or a simple light shielding device.

Also, related to the downsizing and cylindrical design of the packaging, in conventional automatic processors, the photographic processing tank including the film transport system has a darkroom structure (in automatic processors for disk film, color negatives are stored up to the washing tank sb). For film, etc., the bleach tank BL is required), making the structure complicated or large.Furthermore, if a problem occurs in the darkroom, it is not only difficult to locate the problem, but also difficult to open. Since this was not possible, it took a lot of time to repair it.

Furthermore, when processing film at home without requesting a laboratory, there is a sense of anxiety if the disc film or cartridge being processed cannot be seen.

D. Compensation and automation of photographic performance: In photographic processing, there are variations in photographic performance depending on developing processing conditions such as temperature and time, and considerable skill is required, but there is a limit to the availability of skilled personnel. In addition, since the work is complicated, it is desirable to automate at least the important parts of photographic processing so that uniform and high-quality development can be achieved with simple operations that do not require skill.

Incidentally, as mentioned above, a kit for developing a roll film together with the magazine is also known.

It cannot be used for disc film.

E. Reducing the amount of photographic processing solution: In conventional automatic processing machines, the photographic processing solution is discharged from the processing tank by overflow by newly supplying replenisher, but it is expected that the solution will be scattered in various places. Considering the delivery of photographic processing solutions to dealers, the treatment of photographic processing waste solution (overflow solution), etc., it is desirable to be able to perform photographic processing with a small amount of developing processing solution, including washing water.

In addition, in conventional large-scale automatic processing machines, components consumed during photographic processing or eluted and concentrated components are regenerated by replenishing replenisher, so developer activity varies depending on continuous processing conditions. Therefore, the results may vary depending on the lab or season, but stable results can be expected by constantly using a small amount of a newly adjusted photographic processing solution.

Furthermore, reducing the amount of photographic processing solution allows for easy temperature adjustment.
Moreover, there is an advantage that temperature can be adjusted with less energy. Another advantage is that unprecedented temperature control such as changing the temperature of the processing liquid during photographic processing becomes possible.

Furthermore, a specific object of the present invention is to supply a photographic processing liquid into a cartridge in which a photographed disc film is housed, and to develop the disc film while it is still stored in the cartridge while rotating the disc film. The object of the present invention is to clarify a method for developing a disc film, which is characterized by processing.

[Means to solve problems]

A preferred embodiment of the present invention that achieves the above object is:
It is as follows.

In other words, a developing processor having no substantially light-shielded portions holds a cartridge in which a photographed disc film is stored, and photographs the disc film while it is stored in the cartridge. .

Unless there is any particular limitation, the cartridge used in the present invention includes both a conventional disk film cartridge and a cartridge improved to be easily used in the photo processing system of the present invention. .

The cartridge may be held by pressing from one bottom side or one side of the cartridge, or by pressing the suction port against the top or bottom of the cartridge by vacuum suction. Alternatively, a recess may be formed in the base and the cartridge may be placed in the recess.

Alternatively, the cartridge may be held together with the disk film by pressing and sandwiching the core portion of the disk film from both sides.

The posture of the cartridge when holding it is
Horizontal, vertical, inclined, etc. are arbitrary.

Furthermore, the method for holding the cartridge described above is limited because it is related to the means for destroying the cartridge, the photographic processing method including the method for supplying photographic processing liquid, the disk film rotation mechanism, the temperature control means, etc., which will be described later. isn't it.

The mechanism for holding the cartridge in the processing machine is arbitrary, and any conventionally known method may be used. Preferably, the processing machine has a cartridge input port, and the cartridges inserted through the input port are sent to and held by a kitrail or other conveying means to the cartridge holding section. Alternatively, a method may be used in which the cartridge is directly attached to the cartridge holder by hand without using such means, and there is no particular limitation.

During the development process, the disc film is placed against the cartridge.
rotated relative to each other.

By rotating, uneven development processing due to uneven contact with the processing liquid can be avoided, and homogeneous processing without so-called uneven development can be performed.

In addition, rotation improves processing efficiency, and compared to the case where rotation is not performed, processing time is not only significantly shortened, but also the graininess of the image is improved.

The mechanism for rotating the disc film is to prepare a rotating shaft that is rotated directly by a motor or via a drive transmission mechanism, and to rotate the disc film by engaging the rotating shaft with the hub of the disc film through the disc core. It is preferable to do so.

The rotation of the disc film is relative, so the outside of the cartridge must be held down by a holding device such as a stopper, or
Alternatively, by forming a recess in the base and storing the cartridge in the recess, the cartridge may be fixed and the disc film rotated, or conversely, the disc film may be fixed so as not to rotate. The outer cartridge may also be rotated.

Various methods can be used to supply photographic processing liquid to the disk film surface, such as immersion, single drop injection, coating, and spraying. It is arbitrarily selected depending on the photographic processing method, such as a photographic processing method that does not use an external (auxiliary) processing tank, or a photographic processing method that uses an external (auxiliary) processing tank.

In addition, in order to supply photographic processing liquid into the cartridge, for example, openings of the cartridge itself such as an exposure window and a light shielding plate operation part are used, and a new photographic processing liquid is supplied separately from these openings. In some cases, an opening may be provided for use.

Further, the end face of the cartridge may be covered with tape or the like to prevent the supplied photographic processing liquid from leaking, and the cartridge holding means may also serve as a means for preventing leakage of the photographic processing liquid.

When a cartridge is immersed in a photographic processing solution in a processing tank, if the cartridge is held vertically and immersed, the bottom area of the processing tank can be made smaller compared to when it is held horizontally and immersed, making the apparatus more compact. It is beneficial to
In this case, for example, by immersing the cartridge slightly above the exposure window and rotating the disk film, the photographic processing liquid can be supplied to the entire surface of the disk film, which is useful for reducing the amount of processing liquid.

In addition, for those that hold the cartridge horizontally, 1
For example, if a plurality of cartridges are mounted horizontally on one rotating shaft, it is only necessary to supply photographic processing liquid according to the number of mounted sheets, which is effective for switching between single-sheet processing and multi-sheet processing.

Cartridge transportation in the photo processing process, that is, moving the held cartridge (or conversely, the cartridge is fixed and the processing tank side is moved vertically, horizontally, circumferentially, etc.) to each processing tank. This can be done by various known means.

The configuration and arrangement of the photographic processing tanks are not particularly critical; if they are arranged linearly, there will be a CD tank, a BF tank (or a BL tank,
FIX tank), Sb tank (or washing tank), three or four treatment tanks can be arranged in series or parallel, or arranged in a ring shape, etc., or can be arbitrarily configured.

It is also preferable to carry out photographic processing by supplying photographic processing liquid one after another without moving the cartridge.

In methods that basically do not use a processing tank, such as methods in which photographic processing liquid is injected into the cartridge, or in methods that use one auxiliary processing tank, a cartridge transport mechanism is not required. Photographic processing can be performed with the cartridge fixed in place.

In this type of system, it is preferable to replace the processing solution by injecting it with the preceding processing solution still in it, as no special method is required, or by installing cleaning means such as applying pressure with compressed air. Also preferable is a method in which the preceding treatment liquid is removed and then injected. In this case, the amount of treatment liquid can be reduced because the activity does not decrease due to mixing with the preceding treatment liquid.

As in the past, these processing liquids are dispensed from a processing liquid container containing a large amount (multiple batches) of processing liquid in an amount necessary for, for example, photographic processing of one disc film or multiple disc films. However, it is preferable that the treatment liquid be supplied as a kit in a cassette or bag containing each treatment liquid in the amount necessary for processing one disc film.

Preferably, such a cassette or the like can be installed directly into a processing machine. Furthermore, in the processing machine, the processing liquid (cassette) can be selected and applied directly to the disk film surface, or preferably to the processing tank. Preferably, the processing liquid is supplied.

It is preferable that the processing machine is equipped with a temperature control means to ensure a stable processing temperature.
Although the heat transfer method etc. are not limited, it is preferable to pay attention to the following points.

The processing liquid has a high specific heat and a low heat transfer coefficient compared to a (metallic) holding device, so it is preferable to prepare it in a preheated and kept warm state. The temperature, gJf!, of these and the surrounding space or components before or during processing is easily influenced by the temperature of the disc film and the disc film. i is preferable.

The above operation can be performed more stably and effectively by reducing the amount of processing solution used, and by setting the processing temperature high in the early stage of one-color development and low in the latter stage, etc. It also becomes possible to perform operations to make the image finer.

It is preferable that the processing apparatus is provided with a drying means, and in the case of a method in which the disc film is removed from the cartridge and dried, it may be dried by natural drying.

In order to dry the disc film without removing it from the cartridge, it is preferable, for example, to draw warm dry air into the cartridge and dry it while pushing out the processing liquid remaining in the cartridge, and the disc film is stored in the cartridge. Since it is in its original condition, it is convenient for organizing the disc film. By making a new hole in the side plate of the label that corresponds to the exposure window on the exposure window side plate, you can print it as is or hang it on a video etc. It is also possible.

However, for efficient drying and rapid processing, it is preferable to destroy the cartridge and release the film before the drying process.

Any means for destroying the cartridge may be used as long as it does not damage the disc film; a reprint destruction device may be used, or the cartridge may be destroyed manually.

If the cartridge is destroyed at least before the drying process,
The preferred zero rotation of the film during the drying process allows water droplets on the surface to be brushed off and speeds up the drying rate. It is also preferable to blow dry air onto the surface of the film, and it is more preferable to blow dry air while rotating the film at zero rotation, which significantly shortens the drying time.

When using a conventional disc film cartridge as a cartridge, destruction of the cartridge is
Preferably, this is done after the CD.

The sense of security that bright room treatment provides is most apparent at this time. That is, when the cartridge is destroyed and the film is exposed, the image will gradually appear more clearly on the disk surface as the processing steps progress.

It is also preferable to utilize one of the cartridges as a processing tank after releasing the cartridges.

After the disc film dries, it is preferable that the disc film is automatically ejected from the processing machine while remaining in the cartridge or taken out from the cartridge, but it may also be ejected manually. .

Various mechanisms can be adopted as the automatic ejection mechanism, but for example, after processing is completed, the cartridge or disc film holding device is released and the cartridge or disc film is released onto the guide rail or guide plate and automatically ejected to the outside. It is preferable that the

It is preferable that the processing machine is equipped with a waste liquid treatment means A. In this invention, since the amount of photographic processing (waste) liquid discharged is small, for example, a water absorbing material such as an absorbent resin is used. The waste liquid can be absorbed and disposed of by wrapping it in non-waterproof material such as vinyl. Also,
In this case.

It is also more preferable to mix a deodorizing material such as activated carbon to absorb malodorous components. It is also preferable to reduce the amount of waste liquid to be discarded by evaporating the water content and concentrating or drying the waste liquid.

Although one preferred embodiment of the present invention has been described above, these may be combined in any manner, and the present invention is not limited to the described embodiment.

〔Example〕

Next, the disc film development method of the present invention will be explained in detail.

A feature of the present invention is that a photographic processing liquid is supplied into a cartridge containing a photographed disc film, and the disc film inside the cartridge is rotated and developed while the disc film is still stored in the cartridge. FIG. 1 is a schematic diagram thereof. That is, in this section, IO is a cartridge that houses a disc film 20, and the details of this disc film unit are shown in FIGS. 2 to 4. 30 is a rotating shaft, the chuck portion 31 of which is held in the opening of the hub 21 of the disk film 20, and the rotating shaft 3
By rotating the disk film 20, the disk film 20 rotates within the cartridge 10.

1O is a means for rubbing the emulsion surface of the disk film 20, and is used in a preferred embodiment, and a roller, sponge, etc. is placed in contact with the exposure window 12 of the cartridge 10.
The emulsion surface of the disk film 20 is brought into contact with the emulsion surface of the disk film 20 as the disk film 20 rotates.

Next, an apparatus to which the disc film development method of the present invention is applied will be described, but first, the disc film and cartridge will be described.

The disc film and cartridge to which the present invention is applied will be explained.

2 to 4 show disc film units currently on the market. In one drawing, IO is a cartridge, and FIG. 2 is a plan view seen from the exposure window side.
FIG. 3 is a bottom view showing the label side. FIG. 4 is a plan view of the stored disc film 20 viewed from the emulsion side.

The exposure window side plate 11 has an exposure window 12, a central opening 13, a window 14 for opening and closing the light shielding plate, and a bottle insertion hole 1 for opening and closing the light shielding plate.
5. Openings 16 for destroying the cartridge are provided.

Inside the exposure window 12, a light-shielding plate 17 is arranged concentrically with the disc film 20, and while inserting and pressing the bottle through the bottle insertion hole 15 for opening and closing the light-shielding plate, the light-shielding plate 17 is exposed to the window 14 for opening and closing the light-shielding plate. By rotating the light-shielding plate 17 using the protrusion, the disk film 2° is exposed at the exposure window 12.

The central opening 13 has a hub 21 of the disc film 2o.
is exposed.

Disc film cameras incorporate a mechanism for opening and closing the light-shielding plate and a mechanism for rotating the disc film, and use the above-mentioned openings to expose and shield the emulsion surface of the disc film by opening and closing the light-shielding window. The frame of the disc film is advanced.

The photographed disc film unit is sent to a laboratory through a distributor, and at the laboratory, the cartridge 10 is first destroyed in a dark room operation using a special cartridge opener, and the disc film 20 is taken out.

To destroy the cartridge 10, basically, insert a bottle through the cartridge destruction openings 16 provided in the exposure window side plate 11 of the cartridge 10, push out the label side plate 17, and separate the exposure window side plate 11 and the label side plate. This is done by breaking the joint with 18. In addition to this basic operation, the end of the cartridge IO may be cut off, and the end of the label side plate 18 may be pushed out or pulled.

In order to be used in the novel photographic processing system of the present invention, a disc film is housed in a cartridge, the whole cartridge is attached to a camera, and a photograph is taken, and the disc film can be easily photographed while it is housed in the cartridge. In the disc film unit improved as described above, preferably, in order to be able to be mounted on disc cameras of other companies, the external shapes of the cartridge 10 and the disc film 20 in the above-mentioned conventional disc film unit are not changed. Moreover, while the operation of the light-shielding plate and the frame feeding mechanism of the disk film 20 are shared, the structure for mounting or holding the cartridge in the developing machine, the structure for supplying and discharging the photographic processing liquid into the cartridge, and the structure for preventing the cartridge from being destroyed. Add structure etc. for

In addition, if the disc film unit used is not shared with other companies' cameras, there are no restrictions on the standards, and a wide range of structures or mechanisms that are optimal for use in the novel photographic processing system of the present invention can be adopted. It is.

Example 1: In this example, a disc film is developed by a dipping method while it is housed in a cartridge. That is, the cartridge is used as a light-shielding structure (container) for the disc film during the development process, and the development process is performed by allowing the development solution to enter through the gap or opening of the cartridge.

Referring to FIG. 6, reference numeral 10 denotes a cartridge of a film unit in which a photographed disc film is housed, and the cartridge 10 houses a film to be developed.

First, when the process start switch is turned ON, the vertical movement rod 121 of the transport system 120 is lowered, and the chuck 122 formed at its tip engages the center hole of the cartridge 10. Take advantage of
Grasp the cartridge IO and the rod 121 rises 0
Next, the rod 121 moves to the right in the drawing along the guide rail 122 and stops at the color developer tank CD.
As the rod 121 descends, the disc film (cartridge 10) is immersed in the color development processing solution, and the development processing solution enters the cartridge 10 through gaps such as the exposure window or the central opening, and the disc film is immersed in the color development processing solution. The emulsion surface is wetted and color development processing is performed. After a certain period of time has elapsed, the rondo 121 retains the cartridge 10.
It rises again, and development processing is performed in the same manner using the bleach-fix tank BF, the water washing alternative stabilization tank SB, and the dry explosion section.
When the above development processing is completed, the cartridge 10 reaches the finishing table 131, is released from the chuck 122 of the rod 121, and is viewed on the finishing table 131 or dropped from the finishing table 131.

The configuration of the development processing tank shown in the figure is shown as a typical example, and is not limited to what is shown in the figure. For example,
It also includes other tanks 4R, such as color developing tank CD, bleaching tank Bl, fixing tank FIX, washing alternative stabilizing tank sb, and those having a second stabilizing tank.

Further, for example, even in the illustrated example, the drying section may not necessarily be provided; in this case, the cartridge 10 may be broken and the disc film taken out and dried after the water-washing stabilization process is completed; , the entire cartridge IO may be sent to a separate drying means for drying.

The chuck mechanism of the transport system 120 includes the chuck 121 that fixes the cartridge 10 to the tip of the rod 121 and transports it, the start stage 130, and the finish stage 131.
For example, the disc film supply bag described in Jitsukai No. 59-170845 can be used.

As an alternative to the horizontal chuck a, there may be one that transports the cartridge 10 by placing it on a plate, a net, etc., one that transports the cartridge 10 by grasping a part of the cartridge 10, or various other types. It is possible to design.

The entire transport system 120 is not limited to the configuration shown in the drawings, and can be designed in various ways, and the cartridges can be arranged by arranging the processing tanks radially and moving the rods 121 in the circumferential direction. 10 to each developing tank - 1 Conversely, the position of the rod 121 may be fixed, each developing tank may be arranged radially on a turntable, and each developing tank may be moved and guided. good.

The illustrated conveyance system 120 is, for example, installed inside the rod 121 itself or the rod 121 for the purpose of stabilizing the development process and improving sharpness by stable processing liquid shear force and contact effect on the disk film emulsion surface. It also includes a mechanism for rotating the disc film within the cartridge 10 using a rotating rod.

In the case of the embodiment described above, the disk film may be fixed and the cartridge side may be rotated, both may be rotated in opposite directions, or the disk film may be reversed or the center of rotation may be eccentric. preferable.

Furthermore, if the rotation speed is too high, the emulsion surface of the disk film may be scratched and spread, so it is not necessary to rotate at a high speed.

Furthermore, as shown in FIG. 5, one or more cartridges 10 may be suspended and the whole or a portion thereof may be immersed. In such an embodiment, the entire cartridge 10 or the disk film may be rotated. It is necessary to provide a mechanism.

In the illustrated developing processing apparatus, since the cartridge 1° has a light shielding part, all or part of the frame of each processing tank,
Alternatively, the frame for the top cover may be made of a transparent material, or even the top portion may be left open. Even if the frame for the cover is opaque, it also includes a frame that can be freely removed.

Although not shown in the drawings, an embodiment is also included in which the color developing tank CD is provided with a means for destroying a portion of the cartridge 10 containing the disk film to serve as a supply port for the processing liquid. In this case, if light enters into the cartridge 10 from the supply port, a light-shielding structure may be provided at the light entry portion, or one color developing tank CD and bleaching BL to t!
It is necessary to have a light-shielding structure up to the self-fixing tank BF.

Embodiment 2: In the automatic processor shown in FIGS. 5 and 6, the disk film was immersed together with the cartridge 10 in the processing liquid to perform photographic processing. As shown in the figure, the cartridge 10 itself is used as a tank for photographic processing without providing a photographic processing tank, and the exposure window 11F of the cartridge 10 is opened by an opening of the cartridge 10 itself or by a special device (light shielding). of structure)
Photographic processing is performed while rotating the disc film by supplying photographic processing liquid to the photographic emulsion surface of the disc film by injecting, coating, spraying, etc. using an opening or the like (1) using a processing liquid cassette, for example. Therefore, it is permissible to form the cover member from a transparent material and leave the upper surface open.

Example 3: In the one shown in FIG. 7, cartridge l.

However, in the former case, in addition to coating/dropping, spraying can also be used; for example, in addition to the device shown, an air pump or the like is prepared and the photographic processing liquid in the cassette is sprayed out from a nozzle with an atomizing structure. In the latter case, for example, as shown in FIG.
It also includes an embodiment in which the recess is formed slightly deeper than the thickness of the cartridge 10 so that the processing liquid overflowing from the cartridge 10 is collected in the recess. In such embodiments, the cartridge l
It is also permissible to arrange O so that the exposure window 12 is on the lower side and the emulsion surface of the disk film 20 is on the lower side.

Example 9: In this example, a disc film is subjected to photographic processing by immersion, at least up to the pre-bleaching step without bleaching, while the disc film is housed in a cartridge. That is, the cartridge is used as a light-shielding structure (container) for the disc film during the photoprocessing process, and photoprocessing liquid is allowed to enter through the gaps in the cartridge to perform photoprocessing.

In FIG. 12, IO is a cartridge of a film unit/ ) in which a photographed disc film is stored, and the cartridge 10 containing the disc film 20 to be developed is first placed on the starting stand 130 and prepared.

Thereafter, it is sent to the water washing alternative stabilization tank sb.

In the embodiment shown in FIG. 1, the cartridge 10 is destroyed in the cutting section 140, but it is also possible to dispose the cutting device in or above the bleach-fixing tank BF, or in or above the washing alternative stabilizing tank sb. If installed in a tank, instead of always placing the cutting device in a state where it is filled with the washing substitute stabilizing solution, the cutting device should be placed in a state where it is always filled with the washing substitute stabilizing solution. By operating in the manner of ejecting and relocating the cartridge 10, it is possible not only to prevent corrosion of the cutting device but also to reduce the size of the entire device.

Further, in the illustrated embodiment, even after the cartridge is cut by the cutting blade, the disc film is still engaged with the chuck 122.

The means for destroying the cartridge 10 is as follows: 1. The entire circumference of the cartridge 10 is cut using a cutting blade as shown in the figure. 1. For example, the base end of the cartridge 10 on the exposure window 12 side is cut and the label side plate 18 and the opening side plate are cut. 11, or a device that sticks a nail into the joining surface of the label side plate 18 and the opening side plate 11 from the end opposite to the exposure window 12 and pulls them in opposite directions to separate them, a nail □ Various designs can be made, such as using a rotating blade instead of a rotary blade, and in addition to breaking it by hand or using an opener such as Kodak's Model H, etc., if necessary. It is also possible to use a cartridge opener.

When the above photographic processing is completed, the cartridge 1O reaches the finish table 131 and the cartridge 10 is moved to the char 2 of the rod 121.

Experimental example 1: Color development treatment (liquid volume 71, liquid temperature 40°C, processing time 3 minutes 1

Orpm), water washing treatment (liquid volume 501, liquid temperature 3G℃,
After performing stable processing (continuous supply of 145 ml of liquid, liquid temperature of 33°C, processing time of 2 minutes and 30 seconds), the sample disk film was taken out from the cartridge.

Spin squeeze (liquid temperature: 30°C, processing time: 30 seconds, rotation speed: 200 rpm), and drying (wetting: liquid temperature: 40°C to 80°C, rotation speed: 200 rpm).

The above treatments were performed individually using the following treatment liquid supply method.

A, The tip of the processing liquid cassette was inserted into the bottle hole for opening and closing the light shielding plate, and the processing liquid was injected. During the treatment, the window for opening and closing the light shielding plate was pressed with a soft member such as rubber.

B. While pressing the window for opening and closing the light shielding plate with a soft material such as rubber,
A liquid passage was provided in the soft member, and the processing liquid was injected by inserting the tip of the processing liquid cassette.

C. The light-shielding plate of the exposure window was opened and the processing solution was dropped onto the emulsion surface of the disc film.

D. A processing solution was stored in a processing tank, a cartridge containing a sample disk film was immersed in the processing solution, and the processing solution was allowed to enter the cartridge through an opening in the cartridge itself. During processing, the cartridge was fixed and only the sample disk film was rotated.

The processing liquid was supplied in the same manner as in E and D, and during processing, the sample disk film was not rotated but the entire cartridge was reciprocated in the vertical direction.

The processing liquid was supplied in the same manner as in F and D, and during processing, the processing tank was rocked without rotating the sample disk film.

The development unevenness caused by scratches on the emulsion surface and Dmax due to the above processing were investigated and the results were as follows.

Scratches Uneven development DIIIK A Δ OO B Δ oO Coo OD Δ 00 EOO0 FOO Δ ~ 0 0 is equivalent to standard processing data, Δ is inferior to standard processing data but does not pose any problem in terms of photographic performance, and the sample disc film was inserted into the cartridge. Although there are some scratches on the emulsion surface, there is no problem with the photographic performance.For the above reasons, compared to the standard processing speed, the same photograph can be obtained with a much slower rotation speed. It was found that high performance was obtained.

Experimental example 2: G. Open the light shielding plate of the cartridge and look through the exposure window.

Insert a roller and apply a color development processing solution to the emulsion surface, and perform the color development processing in Experimental Example 1 at a processing temperature of 40°C for a processing time of 2.
The processing was performed at a time of 45 seconds and a rotational speed of the disk film of 1Orpm.

H. Open the light shielding plate of the cartridge and look through the exposure window.

A color development treatment solution was supplied to the emulsion surface by spraying, and the color development treatment in Experimental Example 1 was carried out at a treatment temperature of 40°C and a treatment time of 3.
For 15 seconds, the disc film was rotated at 10 rpm.

■Open the light-shielding plate of the cartridge, use air pressure to force the processing liquid in the cassette into the cartridge through the exposure window, and after processing, use air pressure to discharge the processing liquid inside the cartridge and supply the processing liquid for the next process. I decided to do so. Experimental example 1
The color development treatment was performed in place of a treatment temperature of 40° C., a treatment time of 3 minutes and 15 seconds, and a rotation speed of the disc film of 10 rpm.

Experimental example 3: Rotating the disc film while it is stored in the cartridge (
The processing time was compared between one in which the film was developed using a conventional automatic processor for disk film, and one in which the film was developed using a conventional automatic processor for disk film.

In color development processing, at a processing solution temperature of 38°C, there was no significant difference between 3 minutes for the method of the present invention and 3 minutes and 15 seconds for the conventional method, but in bleaching processing, the time for the method of the present invention was 4 minutes and the conventional method Furthermore, in the fixing process, the method of the present invention took 2 minutes and the conventional method took 3 minutes and 15 seconds, so the method of the present invention was clearly more effective in rapid processing.

Experimental Example 4: A comparison was made between a case where the disk film was rotated and a case where the disk film was not rotated during the development process. At the same time, we conducted an experiment to determine the difference in the method of supplying the processing liquid. As a result, with the method of injecting the processing liquid into the cartridge, it was possible to obtain a good image with no uneven development after 3 minutes of processing when the cartridge was rotated once, whereas with the method of injecting the processing liquid into the cartridge, it was possible to obtain a good image without uneven development in 3 minutes. Uneven development occurred.

In the case of a method that oversupplies processing liquid and collects the processing liquid around the cartridge, the rotating type showed no uneven development after 2 minutes and 45 seconds of processing, while the non-rotating type showed no uneven development after 6 minutes of processing. Uneven development occurred.

Even with a supply method in which the processing liquid is immersed in the cartridge, for example, up to the slightly upper part of the exposure window, a good image without uneven development was obtained with a rotating cartridge after 3 minutes of processing, but it is impossible to implement a cartridge that does not rotate once.

Similarly, when applying with a sponge or the like, a good image was obtained in 2 minutes and 30 seconds when the coating was rotated once, but it was impossible to apply it when the sponge was not rotated once.

Experimental Example 5: Next, by changing the rotation speed of the disc film,
Experiments were conducted on the time required to reach Dmax, the occurrence of scratches on the emulsion surface, and the graininess, and the following results were obtained.

Rotation speed BLLIE Deax Scratch Graininess (rpm) 1 3 minutes 45 seconds None -103 minutes
None + 30 2 minutes 40 seconds None ++50
2 minutes 35 seconds Occurred slightly ++100
2 minutes 30 seconds Occurred a little ++ From the above,
By constantly supplying new processing liquid, processing stability can be improved and processing time can be shortened.Also, by processing while rotating the disk film, uneven development can be minimized and the process can be completed in one rotation. It has been found that setting the number appropriately has the advantage of preventing scratches.

Furthermore, it has been found that there is no need for a connecting means for the processing liquid to flow the processing liquid.

Experimental example 6: Disc film is processed in a cartridge,
The development unevenness and occurrence of scratches were compared between a conventional automatic developing machine for disc films, one in which the disc film was processed while rotating, and one in which the disc film was not rotated.

Conventional equipment that rotates disk film
There were no scratches during the color development process at a solution temperature of 38°C for 3 minutes and 15 seconds, but uneven development occurred.
No uneven development or scratches occurred after processing for minutes and 15 seconds.

If the disc film is processed in a cartridge and the disc film is not rotated, the liquid temperature is 3.
8℃, processing time 4 minutes, the liquid temperature of the rotating object is 38℃
, the treatment time was 3 minutes, and the number of revolutions was 10 rpm, the results were the same as those of the conventional method in which the disk film was not rotated and those in which it was rotated.

From this, it has been found that the method in which the disc film is processed in the cartridge can provide equivalent photographic performance compared to the conventional method, and at the same time is superior in shortening the time required for one process.

Experimental Example 7: As a result of performing sensitometry on the disk film used in Experimental Example 6, which was subjected to stepwise exposure, the cartridge was destroyed after regular BL processing, and subsequent processing was performed, the maximum density D mat was as follows. Regular one layer is 2.8 ~
3. O, Orun layer is 2.2-2.3, Panchromatic layer is 1.
It was 8 to 1.9.

Experimental Example 8: The photographic processing solution was supplied into the cartridge using the bond dipping method, the injection method from the cartridge opening using a cassette, the roller coating method, the spraying method, and the drilling method. ~40.5°C and store 1O of disc film for each in a bright room.
Development processing was performed for rp113 minutes, processing solution temperature was 38℃,
When we compared the developability, desilvering properties, uneven development, etc. with those processed in a standard darkroom with a processing time of 3 minutes and 15 seconds, the results were comparable, and the emulsion surface was not scratched.
It was demonstrated that it is possible to process disc film in a cartridge in a bright room.

Experimental example 9: Using sample disk film, supplied processing liquid temperature 38℃1
Color development CD processing 3 minutes 15 seconds, bleaching BLL processing 6 minutes 30 seconds, fixing FIX processing 3 minutes 15 seconds, stable SST processing 4 minutes 30 seconds
3 seconds, and supply the processing liquid into the cartridge for 30 seconds.
Release the disc film from the cartridge that rotates at rpm.

A, BL immersion 3 sand B. After completing BLL, C. During FIX processing, D. After FIX processing is completed.

E. SST processing in progress.

F. After SST processing is completed, G. Drying.

After H0 drying, the emulsion surface was inspected for scratches by dividing it into each section.
As a result, there are no scratches on A and B, there are slight scratches on C and D but they do not affect the screen, and E and F have scratches but they do not affect the screen. G and H had large scratches that affected the screen.

From the above experiments, it has been found that it is particularly preferable to release the cartridge after BL processing. It has also been found that the same effect can be obtained by rotating the disc film at a lower speed than the standard processing disc film rotation speed.

Experimental Example 1O: In Experimental Example 9, an experiment was carried out by changing to a method in which color development CD processing was followed by bleach-fixing BF processing. With regard to development, it has turned out to be particularly favorable. In Experimental Examples 9 and 10, a mechanical method using a cartridge opener and a one-handed method for releasing the cartridge were compared, but no effect was observed on the image.

Experimental Example 11: Development processing was performed while rotating in a dark room using a conventional automatic processor for disc film, and development processing was performed while rotating the disc film inside the cartridge in a bright room, and the cartridge was destroyed just before drying. The performance of the disc film was compared with that of a dried disc film.

In addition, in the case of color development CD processing using a conventional device, the liquid temperature is 38
℃ and a treatment time of 3 minutes and 30 seconds.1 The present invention was treated at a liquid temperature of 38℃ for 3 minutes, and the liquid temperature was 55℃.
The bleaching, BLt constant JFIX, and stable SST treatments were performed under the same conditions. As a result, there was no difference in processing unevenness, and in terms of graininess, there was no difference between the conventional method and the one processed at 38°C for 3 minutes according to the present invention, and the one processed at 55°C for 1 minute was superior to both. Graininess was obtained.

From the above experiments, the processing method according to the present invention not only shows no difference in photographic performance compared to conventional processing methods, but also has the advantage of short processing times.
It has been found that there is an advantage in improving graininess.

Experimental Example 12: When performing photographic processing while rotating a disc film, a resistive member is placed near the emulsion surface of the disc film to provide resistance to the flow of the processing solution. Change the distance to the rotation speed 3
The experiment was conducted using Orpm and a development processing time of 3 minutes and 15 seconds. In addition, rotation fi 200 rpm of standard processing, Dma
Let x be lOO.

Distance (ms) D wax lo 30 0.5 101 From this experiment, it was found that the effect of the resistance member on processability was significant and that sufficient image density could be obtained even when the disk film was rotated at low speed due to the presence of the resistance member.

Experimental Example 13: The processing tank shown in the figure or a container having a shape corresponding to the concave portion made of a synthetic resin material, such as polyethylene phthalate, containing a photographic processing solution and used as a processing tank was used to process photographs using each of the devices shown in the figure. A processing experiment was conducted. As a result, the same processing results were obtained as compared with the case where the photographic processing liquid is supplied to a processing tank or a recess prepared separately from the photographic processing liquid.

〔effect〕

According to the disk film development processing apparatus of the present invention, there are advantages such as speed of processing, miniaturization and simplicity of the apparatus, ease of operation, improvement in the quality and stability of photographic performance, and reduction in the amount of photographic processing solution. In particular, A. Since the disc film can be developed while being rotated while still being stored in the cartridge,
Uneven development due to uneven contact can be avoided,
It is able to prevent the occurrence of uneven development, and rotation improves processing performance, which not only significantly shortens processing time compared to those that do not rotate once, but also has the advantage of improving image graininess. .

In addition, since there is virtually no need to provide a darkroom section in the disc film development processing device, the device can be made smaller and simpler, and there is no need for darkroom processing that requires specialized knowledge or skill, making it easier to operate. It can be provided at low cost.

B. Processing can be carried out in a bright room, so even if a problem occurs within the device, it can be visually checked, allowing the problem to be dealt with early and providing peace of mind.
Since the processing steps can be visually observed, the processing time is advantageously shortened.

C. You can freely switch between processing one disk film or processing multiple disk films, and you can freely set the size of the processing tank, amount of processing liquid, etc. according to the number of sheets to be processed.
It is possible to reduce the amount of processing liquid, improve the stability of photographic processing, and also have the advantage of being advantageous for processing waste liquid of photographic processing.
