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 narrow spaces such as camera stores, DPE distributors, film retail stores, etc., and it can perform developing processing with good photographic performance with 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 device is larger than the disk camera discussed here, and it is not possible to obtain hard copies with high resolution and sharpness such as silver halide photography.

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 this invention is to clarify a novel photo processing system that allows photographed images to be viewed visually.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.

U.S. Pat. No. 4,204,773, O generally, is described in Kodak Red Tisk Film System Complete Guide (Shashin Kogyo, 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 35 weight 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
Photography 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, the number of disc film consumers in Japan is only 2 to 3% of amateur photography film (mainly 35 mm roll film), and 1. The amount of development processing accepted at camera stores these days is extremely small, only a few sets and zero cassettes, and intensive processing by laboratories as described above is inevitable. This has resulted in turning our backs on consumer needs for shorter processing (waiting) times, such as one day, several hours, or even an hour from store reception to delivery, which has been particularly noticeable in recent years for 35mm roll film. .

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 includes a replenisher tank, a treatment liquid replenisher, a waste liquid tank, and flush water piping, etc., which not only makes it unnecessarily large, but also makes operation complicated, including darkroom operation in case of trouble. Since this requires a certain level of specialized knowledge, it is difficult to install it in a camera store and provide development processing services at a single store, and this goes against the desire to shorten processing (waiting) time.

The 351111 roll film is water-free, has no piping, is table-sized, and enables in-store service with short processing times (within 1 hour).The photo processing equipment manufacturers are responding to the trend toward minilabs by using disc film or disk film. The ease of operation and handling that the camera has compared to the 3510-LeFilm or camera,
This cancels out the advantages of compactness and ease of organizing photographed film, hindering the spread of disc film, and creating 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 film you have shot 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 demand of wanting to view images as soon as they are taken, but the more this happens, the stronger the demand for shortening the 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 that the processing machine can process at most 1 to 2 sheets, the size of the processing machine is as small as possible (for example, a desktop type), and the operation is simpler than described above (i.e., just a button). (or no need for complicated darkroom operations).

In view of the above-mentioned points, the present researchers have arrived at the present invention as a result of intensive research.1 The general purpose of the present invention is to solve the following problems.

A. Rapid processing: As with roll film, DPE using disc film is intensively performed in a laboratory, so it can be completed as quickly as the same day by requesting it to a distributor, but normally takes two or more 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 located unevenly, and as long as photo processing is done in the lab, it is not possible to satisfy the desire to make the photograph visible immediately after the photograph is taken.Therefore, in order to satisfy this desire, it is necessary to places, such as camera stores,
It is desired to make it possible to carry out photographic processing at conventional DPE distributors, film retailers, etc., and furthermore, to make in-house processing possible.

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 developing machines require a considerable amount of installation space even if they are small.

It is desired to significantly downsize the device.

C1 Bright room processing: Except for camera shops that have traditionally processed photographs, if you want to install it in a place that does not have dark room equipment, you will need a bright room or a bright room, considering the installation space and cost of adding new dark room equipment. It would be desirable to be able to perform photographic processing using a simple light shielding device.

Also, related to the miniaturization and simplification of equipment, in conventional automatic processors, the photographic processing tank including the film transport system has a darkroom structure (in automatic processors for disk film, up to the washing tank SB, color negative film etc. (up to the bleach tank BL), which causes the structure to become complicated or large, and if a problem occurs in the darkroom,
Not only was it difficult to locate the problem, but it also took a lot of time to repair because it couldn't be opened.

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, variations in photographic performance are likely to occur depending on development processing conditions such as temperature and time, and considerable skill is required, but there is a limit to the availability of skilled personnel. Further, 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.

As mentioned above, kits for developing roll films together with magazines are also known, but these kits cannot be used for disc films.

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. The final product may vary depending on the lab or season, but it is always 2g.
A stable finish can be expected by performing photo processing using a small amount of the new photo processing solution.

Furthermore, reducing the amount of photographic processing solution allows for easy temperature adjustment.
Moreover, there is an advantage that the temperature can be adjusted to 3381 degrees with less energy. Another advantage is that unprecedented temperature control such as changing the temperature of the processing liquid during photographic processing becomes possible.

As a result of extensive research, the inventors of the present invention found that by processing the disc film in a cartridge, the processing can be carried out in a bright room. It has been found that there is a danger that performance may be significantly impaired.

A specific object of the present invention is, firstly, that the developing process part has a non-light-shielding structure that has virtually no darkroom, so that the installed process or a plurality of disc films can be stored in the cartridge. The purpose of this invention is to clarify a method for developing a disc film, which is characterized by developing it under conditions such as Thirdly, the purpose of the present invention is to clarify a method for developing a disk film in which the emulsion surface of the disk film is less likely to be scratched.Fourthly, the purpose is to provide a method for developing a disk film that is easy to dry. The object of the present invention is to clarify a method for developing a disk film that is less likely to cause stains on the emulsion surface, etc.

[Means for Solving the Problems] A feature of the present invention that achieves the above-mentioned object is that the disc film is removed from the disc cartridge during or between processes after color development processing is performed while stored in the cartridge and the process is stopped. The purpose is to release

As mentioned above, in the current color photographic processing process, the stop processing also serves as bleaching or bleach-fixing processing, so this not only effectively solves the above problem, but also allows the processing of the film to be visually observed in a bright room. , processing safety will be dramatically improved.

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 otherwise specified, the cartridge used in the present invention includes both a conventional disk film cartridge and a cartridge improved to be easily used in the photographic processing system of the present invention.

The cartridge may be held by pressing from the upper and lower surfaces of the cartridge or from the sides, or by pressing the suction port against the upper or lower surface 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. When holding the cartridge, the cartridge may be held in any position, such as horizontally, vertically, or tilted.

Furthermore, the method for holding the cartridge described above is limited as it is related to the means for destroying the cartridge, the method for photographic processing including the method for supplying photographic processing liquid, the rotation mechanism for the disk film, the temperature control means 1, 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 cartridge inserted through the input port is sent to and held by a guide rail 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.
Preferably, they are 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.

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

The mechanism for rotating the disc film includes a rotating shaft that is rotated directly by a motor or via a drive transmission mechanism, and this rotating shaft is engaged with the disc film knob through the disc core to rotate the disc film. It is preferable to rotate.

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 supply methods such as dipping, pouring, dropping, coating, and spraying are used to supply photographic processing liquid to the disk film surface. It is arbitrarily selected depending on the photographic processing method, such as a photographic processing method that does not use a 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, one method is to use the openings of the cartridge itself such as the exposure window and the light-shielding plate operation part, and the other is to supply the photographic processing liquid 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 1, for example, the cartridge is immersed up to a slightly upper portion of the exposure window.

By rotating the disc film, the photographic processing liquid can be supplied to the entire surface of the disc 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 the 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 structure and arrangement of the photographic processing tank are not particularly limited; if arranged linearly, there will be a CD tank, a BF tank (or a BL tank,
It is possible to arbitrarily configure three or four treatment tanks such as FIX tank), Sb tank (also C, water washing tank), or arrange them in series or parallel, or arrange them in a ring.

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 such a system, it is preferable to replace the processing liquid by injecting it with the preceding processing liquid still in it, as no special method is required, or by arranging a 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 directly attached to a processing machine.

Further, in the processing machine, it is preferable that a processing liquid (cassette) is selected and the processing liquid is supplied directly to the disk film surface, or preferably to a processing tank.

It is preferable that the processing machine is provided with a temperature adjustment means to ensure a stable processing temperature, and the type, shape, and installation of the heater in this temperature adjustment means are limited in terms of position 1 heat generation capacity, heat transfer method, etc. However, it is preferable to keep the following points in mind.

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. It is preferable to adjust the temperature of these and the surrounding space or members before or during the processing, since the temperature of the film and the disk film are likely to affect the temperature of the film.

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 perform drying efficiently and to perform 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 commercially available 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 darkroom processing 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 is dried, 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 ejecting mechanism. For example, after processing is completed, the holding device for the cartridge or disc film is released, the film is released onto a guide rail or a guide plate, and the film is automatically ejected to the outside. It is preferable that the

It is preferable that the processing machine is equipped with waste liquid processing means. In this invention, since the amount of photographic processing (waste) liquid discharged is small, the waste liquid may be treated using a water-absorbing material such as an absorbent resin. It can be disposed of by absorbing the water and wrapping it in non-waterproof material such as vinyl. Also,
In this case, it is more preferable to mix a deodorizing material such as activated carbon to absorb the malodorous components, or by blowing warm exhaust air from the treatment machine onto the waste liquid, or by using a separate heating means. Therefore, it is also preferable to reduce the amount of waste liquid to be discarded by evaporating the water in the waste liquid 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.

(Left below) [Example] Next, a method for developing a disc film according to the present invention will be described in detail with reference to an example of the apparatus shown in the attached drawings.

Note that the present invention is not limited to the illustrated device example, and the illustrated device example is merely an example, and details may be rearranged with other illustrated devices, or equivalent devices not shown may be used. The design can be changed to other functional structures.

Prior to explaining the apparatus, the disc film and cartridge to which the present invention is applied will be explained.

Figures 20 to 22 show disk film units currently on the market. In the drawings, 1O is a cartridge, Figure 20 is a plan view as seen from the exposure window side, and Figure 21 is a bottom view. It shows the label side. FIG. 22 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. Central opening 13, window 14 for opening and closing the light shielding plate, 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 by inserting and pressing a pin through the bin 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 operation. By rotating the light shielding plate 17 using the protrusion, the disk film 20 is exposed in the exposure window 12 portion.

The hub 21 of the disc film 20 is placed in the central opening 13.
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 1o, basically, insert a pin 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 1° 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 installed in 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.

Apparatus Example 1: This apparatus example performs photographic processing of a disk film by the immersion method, at least up to the bleach-fixing step without bleaching, while the disk 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. 1, 10 is a cartridge of a film unit in which a photographed disc film is housed;
The cartridge 10 of the disc film 20 to be developed is first placed on the starting stand 130 and prepared. By turning on the processing start switch, the transport system 12
The vertically moving rod 121 of No. 0 is lowered, and the chuck 122 configured at its tip grabs the cartridge 10 using the central hole of the cartridge 10, and the rod 121
then the rod 121 moves up to the guide rail 12
2 to the right in the drawing, and stops at the color developing tank CD, and as the rod 121 descends, the cartridge 1
0 is immersed in a color development processing solution, and the photographic processing solution enters the cartridge 10 through gaps such as the exposure window and central opening, wets the emulsion surface of the disc film, and performs color development processing. . After a certain period of time has elapsed, the rod 121 rises again while holding the cartridge IO,
It is guided to the bleach-fixing tank BF and undergoes bleach-fixing treatment, and then
The disk film is sent to the cutting section 140, and the periphery of the cartridge 10 is cut by a cutting blade 141 of a cutting device synchronized with the rotation of the rod 121, and the disc film is released from the cartridge 10.

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

In the illustrated example of the device, the cartridge 10 is destroyed in the cutting section 140, but the cutting device may also be placed in or above the bleach-fixing tank OF, or in or above the washing alternative stabilizing tank sb. If it is installed in a tank, the cutting device should not be placed in a state where it is always filled with the washing substitute stabilizing solution, but instead 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.

In addition, in the example of the device shown in RILI, 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 includes cutting the entire circumference of the cartridge 10 using a cutting blade as shown in the figure, for example, by cutting the base end of the cartridge 10 on the exposure window lz side and destroying the label side plate 18 and the opening side plate. A device that separates them from each other, or a device that sticks a nail into the joint 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. Alternatively, one using a rotating blade, one punching around the cartridge,
・Furthermore, various designs can be made, such as those shown in the device examples described below, and it is possible to destroy them by hand. It is also possible to use a cartridge opener such as Opener Model H. When the above photographic processing is completed, the cartridge 10 reaches the finishing stand 131, where it is released from the chuck 122 of the rod 121 and dried for a certain period of time. It will be done.

The configuration of the illustrated photographic processing tank is shown as a typical example, and is not limited to what is shown in the figure.
It also includes tank configurations such as those having a color developing tank CD, a bleaching tank BL, a fixing tank FIX, a washing alternative stabilizing tank Sb, and a second stabilizing tank. In this embodiment, the disc film is released from the cartridge IO after being bleached in the bleach tank BL.

Further, for example, in the illustrated example, the drying section does not necessarily have to be provided, and the disc film 20 on the finishing table 131 may be taken out after the water washing process is completed and dried using a separately provided drying means. .

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, a disk film supply device described in Japanese Utility Model Application No. 59-170845 can be used.

As an alternative to the chuck mechanism, there may be one that transports the cartridge IO in a tray, a jll, etc., one that grips and transports a part of the cartridge 10, and various other designs. It is possible.

The entire transport system 120 is not limited to the configuration shown in the drawings, and can be designed in various ways.
A method in which each processing tank is arranged radially and the rod 121 is moved in the circumferential direction to guide the cartridge 10 to each photographic processing tank, or conversely, the position of the rod 121 is fixed and each photographic processing tank is connected to a turntable. They may be arranged radially to move and guide each photographic processing tank.

The illustrated conveyance system 120 is, for example, a rod 121 itself or a rotating system built into the rod 121 for the purpose of stabilizing photographic processing and improving sharpness through stable processing solution shear force and contact effect on the disk film emulsion surface. It also includes a mechanism that rotates the disc film 20 within the cartridge 10 using a rod.

In the case of the embodiment described above, the disk film 20 may be fixed and the cartridge IO side may be rotated, or both may be rotated in opposite directions.

It is also preferable to make the center of rotation eccentric.

Furthermore, if the rotation speed is too high, there is a risk of premature scratches on the emulsion surface of the disk film, so it is not necessary to rotate at a high speed.

Apparatus Example 2: In this example, as shown in FIG. 2, the cartridge 10 is held vertically and photoprocessed by the immersion method. The cartridge is attached to the chuck mechanism 122 that is attached to the chuck mechanism 122 and is supplied to each photoprocessing tank along the guide rail 123.In order to transfer the cartridge to the photoprocessing tank of the 0th step, the guide rail 123 is moved up and down. A method of moving the holding member up and down without changing it.

In addition, a conditioning tank may be provided after the color development process, and the conditioning tank is used to stop the development and accelerate the bleaching reaction, and prevents the developer from being mixed into the bleach-fix solution and its negative effects. The conditioning tank contains, for example, a bleach accelerator and a buffer agent. As the bleaching accelerator, organic sulfur compounds are generally used, including mercapto compounds and thione compounds. Furthermore, acids and alkaline agents such as acetic acid, citric acid, succinic acid, sulfuric acid, and sodium hydroxide are used to adjust the pH of the conditioner. The amount of these bleach accelerators and buffers added is 0.001g per conditioner IIL.
It is used in a range from 100g to 100g. In addition to the above additives, chelating agents and the like may also be added.

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

5ml oversupply, liquid temperature 33℃, processing time 6 minutes 1 rotation speed 3O

After carrying out spin-squeeze (liquid temperature 30°C, processing time 30 seconds, 20 (l)

0Orpm).

The above treatments were performed individually using the following treatment liquid supply method: A. The tip of the treatment liquid cassette was inserted into the pin hole for opening and closing the light shielding plate, and the treatment 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.

The C1 exposure window was shielded from light, the plate 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, and a cartridge containing a sample disk film was immersed in the processing solution, and the processing solution was allowed to enter the cartridge through the color opening of 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 the processing, the sample disk film was not rotated but the entire cartridge was moved upward and downward ISt.

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.

Due to the above processing, scratches occur on the emulsion surface, uneven development, D■a! When I looked into it, it was as follows.

Problem Uneven development Dtaax A Δ OO B Δ 00 coo.

D Δ oO EOO0 FOO Δ ~ 0 0 is equivalent to standard processing data, Δ is inferior to standard processing data, but there is no problem in photographic performance. If the sample disk film is rotated in the cartridge, scratches may occur on the emulsion surface. Although this was observed, there was no problem with the photographic performance, and from the above, it was found that the same photographic performance could be obtained with a much lower rotation speed compared to the standard processing rotation speed.

Experimental example 2: G. Open the light shielding plate of the cartridge and look through the N light 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 spray the color developing solution onto the emulsion surface through the exposure window.

The color development process in Experimental Example 1 was carried out at a processing temperature of 40°C, a processing time of 3 minutes and 15 seconds, and a rotation speed of the disk film of 1° rpm.
Processed instead.

In the process, 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 in the cartridge and supply the processing liquid for the next process. I made it. The color development process in Experimental Example 1 was performed at a processing temperature of 40°C and a processing time of 3 minutes.
The processing was performed for 5 seconds, and the rotation speed of the disk film was changed to 1 Orpm.

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 method of the present invention took 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, a good image with no uneven development could be obtained in 3 minutes with a rotating cartridge, but a 6 minute process with a non-rotating cartridge. Uneven development occurred.

In the case of a method in which the processing liquid is oversupplied and accumulated around the cartridge, the one that rotates once did not cause uneven development after 2 minutes and 45 seconds of processing, whereas the one that does not rotate did so after 6 minutes of processing. Uneven development occurred.

Even with a supply method in which the processing liquid is immersed into the cartridge, for example, up to a slightly upper part of the exposure window, a good image without uneven development was obtained in a 3-minute process using one rotation, but a method that does not involve rotation is impossible.

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 the coating when the coating was not rotated.

Experimental example 5: Next, change the rotation speed of the disc film.

Blue D■a! Experiments were conducted on the arrival time, occurrence of scratches on the emulsion surface, and graininess, and the following results were obtained.

Rotation speed BLUE D+sax Scratch Graininess (rpm), 1 3 minutes 45 seconds None -10
3 minutes None + 30 2 minutes 40 seconds None ++5
0 2 minutes 35 seconds Occurred slightly ++to0
2 minutes 30 seconds Slight occurrence ++ Based on the above, if you always supply new processing liquid, processing stability can be improved and processing time can be shortened.
Also, if you process the disc film while rotating it,
There is less occurrence of uneven development, and if you set the number of revolutions appropriately,
It has been found that this method has the advantage of preventing the occurrence of scratches.

Furthermore, it has been found that there is no need for any means for keeping the processing liquid flowing.

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

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.
For those that rotate once at 8℃ and processing time for 4 minutes, the liquid temperature is 38℃.
, the processing time was 3 minutes, and the rotation speed was 10 rp+w, and the results were the same as those of the conventional method in which the disk film was not rotated and in which it was rotated.

From this, it has been found that the method in which the disc film is processed within the cartridge provides equivalent photographic performance compared to the conventional method, and is also superior in shortening the processing time.

Experimental Example 7: The disk film used in Experimental Example 6 was subjected to stepwise exposure, and after the fixing BL process, the cartridge was destroyed and the subsequent process was performed.As a result of sensitometry, the maximum density Dmax was as follows.

Regular layer is 2.8-3.0, Orun layer is 2.2-2
．． 3. Panchromatic layer was 1.8-1.8.

Experimental Example 8: The method of supplying the photographic processing solution into the cartridge was the dipping method, the injection method from the cartridge opening using a cassette, the roller coating method, the spraying method, and the hole injection method, and the processing solution temperature was 38°C. ~40.5℃, and 1o of disc film for each in a bright room.
RP ■ 3 minutes of development processing was performed, and the development performance, desilvering performance, development unevenness, etc. were compared with those of standard processing in a dark room at a processing solution temperature of 38°C and a processing time of 3 minutes and 15 seconds. There were no scratches on the emulsion surface, demonstrating that it is possible to process the disc film in a cartridge in a bright room.

Experimental Example 9: Using a sample disk film, supply processing liquid temperature: 38°C,
Color development CD processing 3 minutes 15 seconds, bleaching BL processing 6 minutes 30 seconds, constant 1 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.
Releasing the disk film from the cartridge using a device that rotates at rpm: A, 30 seconds after immersion in BL, B, after BL processing, C, during FIX processing, D, after FIX processing, E, during SST processing.

F. After SST processing is completed, G. Drying; After H6 drying.

Scratches on the emulsion surface were examined by performing each step separately.

the result.

For A and B, there are no scratches, for C and D, there are slight scratches but they do not affect the screen, and for E and F, there are scratches but they do not affect the screen. It's something that doesn't exist.

Regarding G and H, the scratches were large and affected the screen.

From the above experiments, it has been found that it is particularly preferable to release the cartridge after the BL process. 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 conducted in which color development CD processing was followed by bleach-fixing without BF processing. With regard to development, it has turned out to be particularly favorable. In addition.

In Experimental Examples 9 and 1O, a mechanical method using a cartridge opener and a manual method were compared as the means for releasing the cartridge, 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 conventional one-color development CD processing, the liquid temperature is 38
℃, treatment time was 3 minutes and 30 seconds, and the one of the present invention was treated for 3 minutes at a liquid temperature of 38℃, and the one treated for 1 minute at a liquid temperature of 55℃, F
The white BL, fixing FIX, and stable SST processes 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 3-minute treatment at 38°C according to the present invention, and the 1-minute treatment at 55°C 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 time.
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 3O
The experiment was conducted at rpm and development processing time of 3 minutes and 15 seconds. In addition, the rotation speed of the standard process was 20 Orpm, and D+*ax was set as Zoo.

Distance 1111 (s+s) Dmaxlo
30 0.5 101 From this experiment, it was found that the effect of the resistance member on processability was remarkable 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: Regarding the processing tank shown in the figure or a container shaped to correspond to the recessed part made of a synthetic resin material, for example, polyethylene phthalate, in which a photographic processing solution is stored and used as a processing tank, the six containers shown in the figure are as follows. A photo 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.
