Abstract

PURPOSE:To improve the processing stability and the sharpness by placing a resistance member in the distance of <= several mm from an emulsion surface, and rotating relatively the disk film and the resistance member. CONSTITUTION:The distance between a disk film 1 and a resistance member 2 is a range extending from '0' to several mm in which both of them are in a contact state. The resistance member 2 is placed while extending over a part or the whole of the emulsion surface of the disk film 1, its concrete shape is optional such as a rod shape, a plate shape, etc., the material is also optional while extending from a soft material to a rigid material, and also, the number of pieces of the resistance member 2 to be placed is also unlimited. That which is used as the resistance member 2 is positioned in the inside surface of a cartridge 10 in a disk film unit. For instance, it is a rubbing contact member such as a light shielding plate 17, a roller, a sponge, etc. The disk film is rotated relatively against the cartridge, when the development processing is being executed. In this way, the processing stability and the sharpness are improved.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for developing a disc film.

[Conventional technology]

Disc film is provided as a film UNIRAD 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. There is.

A large number of disk films are removed from the cartridge by a cartridge opener in a laboratory, set in a large capacity processing tank of an automatic developing machine, and are automatically developed while being rotated at high speed (for example, 200 rpm) in the same direction.

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

[Problem that the invention seeks to solve]

As mentioned above, the development process for disc film involves destroying the cartridge in a dark room and taking out the disc film, followed by color development, bleaching, fixing (or bleach-fixing), and washing with water (
The reality is that each processing step (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 35mm).
The amount of development processing received at a camera store per day is extremely small, only a few sets-0 cassettes, and intensive processing by laboratories as described above is forced. This goes against the consumer's needs to shorten the processing (waiting) time, which has been noticeable in recent years for 35-year-old roll films, such as one day, several hours, or even an hour from in-store reception to delivery. This is the result.

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 is equipped with a replenisher tank, a treatment liquid replenisher, a waste liquid tank, and flush water piping, etc., making it not only unnecessarily large but also complicated to operate, including darkroom operation in case of trouble. , since a certain level of specialized knowledge is required, this precludes installation in camera stores and in-store development processing services, and goes against the goal of shortening processing (waiting) time.

Photo processing equipment manufacturers are responding to the so-called mini-lab trend of 35-layer roll film, which enables over-the-counter service with no water washing, no piping, table size, and short processing time (within 1 hour). This offsets the advantages that disc cameras have over 35 Fengteng roll film or cameras, such as ease of operation, ease of handling, compactness, and ease of organizing film, which hinders the spread of disc films. As a result, the aforementioned vicious cycle is generated.

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 advances in electronic devices in recent years have made it possible to electronically read out color image information from developed films, making it possible to display the information 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 demand of wanting to see images as soon as they are taken, but to a certain extent.

There is an increasing demand for shorter development processing (waiting) times.

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 this as described above. In other words, for this purpose, it is only necessary to be able to process one or two sheets at a time, the processing machine should be as small as possible (for example, a desktop type), and the operation should be simpler than described above (i.e., (No need for one button or complicated darkroom operations).

In view of the above points, the researchers conducted extensive research and found that
The present invention has been achieved, and 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 Place 1 For example, a camera store,
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 the narrow spaces of ordinary camera stores, conventional automatic processors require a considerable amount of installation space even if they are small. It is desirable to 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 important parts of photographic processing to achieve uniform and high-quality development with simple operations that do not require skill.

Incidentally, as mentioned above, a kit for developing one loaf of 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 laboratory or method used, but stable results can be expected by constantly using a small amount of a newly adjusted photographic processing solution.

Furthermore, the reduction in the amount of photographic processing solution has the advantage that temperature adjustment is easy - e', and moreover, temperature adjustment is possible with less energy. Another advantage is that unprecedented temperature control such as changing the temperature of the processing liquid during photographic processing becomes possible.

Further, a specific object of the present invention is to clarify a method for developing a disc film that improves processing stability and sharpness.

[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. .

The cartridge used in the present invention includes, unless otherwise specified, a conventional disk film cartridge and a cartridge improved to be easily used in the photoprocessing system of the present invention. be.

The cartridge may be held by suppressing the cartridge from the upper and lower surfaces 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.

Further, the cartridge 2 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.

Also, how to hold the cartridge mentioned above.

The present invention is related to a cartridge destroying means, a photographic processing method including a method of supplying a photographic processing liquid, a disc film rotation mechanism, a temperature adjusting means 1, etc., which will be described later, and is not limited thereto.

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, not only the processing time is significantly shortened, but also the graininess of one 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, 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, 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,
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 transport in the photo processing process, I! I too,
The means for moving the held cartridge (conversely, the cartridge is fixed and the processing tank side is moved vertically, horizontally, in one circumferential direction, etc.) to each processing tank is performed by various known means. It is something that can be done.

The composition and arrangement of the photographic processing tanks are not particularly particular.If they are arranged in a straight line, there will be three or four processing tanks: CD tank, BF tank (or BL tank, FIX tank), SB tank (or washing JP tank). They can be arranged in any desired configuration, such as arranging them in series or parallel, or arranging 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 the case of such a system, it is preferable to replace the processing liquid by injecting the preceding processing liquid while it is still in the tank, as no special method is required. A method in which the preceding treatment liquid is removed and then injected is also preferred. 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.

The processing machine has a temperature 'f' to ensure stable processing temperature.
It is preferable to provide J4yIi means, and the type, shape, and attachment of the heater in this temperature adjustment means, position 1 heat generation capacity, heat transfer method, etc. are not limited, but 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. It is preferable to adjust the temperature of these and the surrounding space or members thereof before or during the processing, since the temperature is likely to be influenced by the temperature of the disc 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 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; commercially available destruction equipment 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 is dried, it is preferable that the disc film is automatically ejected from the processing machine while being housed in the cartridge or taken out from the cartridge, but it may be taken out by one manual operation.

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 a waste liquid treatment means. In the present 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 to treat the waste liquid. 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 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, a method for developing a disc film according to the present invention will be explained in detail with reference to the accompanying drawings.

In FIG. 1, l is a disk film and 2 is a resistance member. Both the disk film 1 and the resistance member may be immersed in a photographic processing liquid, or the photographic processing liquid may be supplied between the emulsion side of the disk film 1 and the resistance member 2.

The distance between the disc film 1 and the resistance member 2 is preferably within a range of several mm, preferably within 10 m, from 0 mm at which they are in contact.

The resistance member 2 is disposed over part or all of the emulsion surface of the disk film 2, and its specific shape may be arbitrary, such as a rod or a plate, and the material may be arbitrary, from soft to hard. be. Furthermore, there is no limit to the number of resistive members 2 to be arranged.

Specifically, what is carried as the resistance member 2 is, for example, a light shielding plate located on the inner surface of a cartridge in a disc film unit, or a friction member such as a roll or a sponge.

Furthermore, as shown in FIG. 2, the wall surface 2 of the processing tank when one disc film 1 is processed, and the other disc film 1 (2) when processing a plurality of disc films 1 as shown in FIG. ).In the former case, if the width of the processing tank is large, a separate resistance member may be arranged.In the latter case, it is preferable to rotate the adjacent disk films l in different directions, but only one rotation. It may be possible to make a difference in speed, to perform operations such as rotation/stop rotation, or to switch the direction of rotation.

In the case of multiple processing of disc films as shown in FIG. 3, a resistance member may be further arranged between the disc films.

Next, a specific example of an apparatus for carrying out the disc film development method of the present invention will be described in detail with reference to the accompanying drawings.
Prior to this, the disc film or cartridge processed according to the present invention will be explained.

4 to 6 show disc film units currently on the market. In the drawings, 10 is a cartridge, and FIG. 4 is a plan view seen from the exposure window side.
FIG. 5 is a bottom view showing the label side. FIG. 6 is a plan view of the stored disc film 20 viewed from the emulsion side.

Inside the exposure window 12, a light-shielding plate 17 is arranged concentrically with the disc film 20, and while inserting and pressing a pin through the pin 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 20 is exposed in the exposure window 12 portion.

The hub 21 of the disc film 20 is placed in the central opening 13.

Disc film cameras have a built-in 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 advance of the disc film is performed.

The photographed disc film UNI/) is sent to a laboratory through a distributor, and at the laboratory, the cartridge 10 is first destroyed in a dark room using a special cartridge opener, and the disc film 20 is taken out. To destroy the cartridge 10, basically, insert a pin through the openings 16 for cartridge destruction provided in the exposure window side plate 11 of the cartridge 10, push out the label side plate 17, and remove the exposure window side plate ti and the label side plate. This is done by breaking the joint with 18.

In addition to this basic operation, cutting off the end of the cartridge IO,
A pushing or pulling operation of the end of the label side plate 18 may be performed.

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 the cartridge destruction. 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 develops a disc film by a dipping method while it is housed in a cartridge. The same applies to the following device examples, but in the case of the immersion method, for example, a light shielding plate inside the cartridge is used as the resistance member.

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. To explain according to Fig. 7, l
O is a cartridge of a film unit in which a photographed disc film is stored, and a cartridge 10 in which a film to be processed is stored is first.

The cartridge is prepared by being placed on the starting table 130, and when the processing start switch is activated, the vertically moving rod 121 of the transport system 120 is lowered, and the chuck 122 configured at the tip thereof uses the central hole of the cartridge 10. Then, the rod 121 moves to the right in the drawing along the guide rail 122 and stops at the position of the first color developing tank CD, and as the rod 121 descends, the disk film is removed. (Cartridge 1O) is immersed in a color development processing solution, and the development processing solution enters into the cartridge through gaps such as the exposure window and central opening of the cartridge 1O, wets the emulsion surface of the disc film, and performs color development processing. will be held. After a certain period of time,
The rod 121 rises again while holding the cartridge 1O, and the development process is performed in the bleach-fix tank BF and the washing alternative stabilization tank Sb drying section in the same manner. When the development process of 9 or more is completed, it moves to the finish table. 131, the cartridge 10 is released from the chuck 122 of the rod 121 and is dropped directly onto the finishing table 131 or from the finishing table 131.

The configuration of the developing processing tank shown in the figure is shown as a representative example, and is not limited to the one 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.

Furthermore, even in the case shown in FIG. 1, the drying section may not necessarily be provided; in this case, the cartridge 10 may be broken and the disk film taken out and dried after the water washing alternative stabilization process is completed; The entire cartridge 10 may be sent to a separate drying means for drying.

The chuck mechanism of the transport system 120 includes a chuck 121 that fixes the cartridge 10 to the tip of the rod 121 and transports it, a start stage 130, and a finish stage 131.
For example, the 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 10 by placing it on a plate, a net, etc., one that transports the cartridge 10 by grasping a part of it, and various other mechanisms. 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. Also, the processing tanks can be arranged radially and the rods 121 can be moved circumferentially to transport the cartridges. Alternatively, the rod 121 may be fixed in position, the developing tanks may be arranged radially on a turntable, and the developing tanks may be moved and guided. .

The illustrated conveyance system 120 is, for example, installed within the rod 121 itself or inside the rod 121 for the purpose of stabilizing the development process and improving sharpness through stable processing liquid shear force and contact effect on the surface of the DIF film emulsion. It also includes a mechanism that rotates the disc film within the cartridge IO 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, there is a risk that the emulsion surface of the disk film will be damaged, so it is not necessary to rotate at a high speed.

Furthermore, as shown in FIG. 8, one or a plurality of 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 development processing apparatus, since the cartridge 10 has a light shielding function, 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 a means is disposed in the color developing tank CD, in which a portion of the cartridge 10 containing the disk film is destroyed to serve as a supply port for the processing liquid. In this case, if light enters into the cartridge IO from the supply port, a light-shielding structure is provided at the light-invading portion, or a light-shielding structure is provided between the color developing tank C opening and the bleaching BL to bleach-fixing tank BF. There is a need.

Apparatus example 2: In the automatic processor shown in FIGS. 7 and 8, the disk film is immersed together with the cartridge 10 in a 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 is opened by an opening of the cartridge 10 itself, such as the exposure fi 12 of the cartridge 10, or by a special device (light-shielding). It performs photographic processing by supplying photographic processing liquid to the photographic emulsion side of the disc film by injecting, coating, spraying, etc. using an opening (in the structure), for example, using a processing liquid cassette. It is permissible for one member to be made of a transparent material and for the top surface to be open.

This example of the apparatus is also provided with the above-mentioned disk film or cartridge rotation mechanism.

Device Example 3: In the device shown in FIG. 9, a concave portion for storing the processing liquid is formed in the base on which the cartridge 10 is placed to serve as an auxiliary tank.

Apparatus Example 4: This apparatus example is a modification of the apparatus example shown in FIG. 9, and in addition to the configuration shown in the figure, the light-shielding film disposed in the exposure window of the cartridge 10 is replaced by a light-shielding film opening/closing mechanism in a disk camera. A mechanism that opens and closes using a mechanism similar to that shown in FIG. It is also possible to combine it with an embodiment in which a recess for a liquid reservoir is provided as described in .

Apparatus Example 5: In FIG. 10, 200 is a base, and a recess 210 on which a disc film cartridge 1O is placed is formed on its upper surface. The planar shape of the recess 210 is preferably quadrangular, and more preferably corresponds to the outer shape of the cartridge 10.

The depth of the recess 210 is sufficient as long as it is deep enough to sufficiently hold the cartridge cartridge 10 during rotation of the isk film, which will be described later. Further, the upper surface of the base 200 is made smooth, and instead of the recessed part 210, continuous or discontinuous protrusions corresponding to the outer shape of the cartridge 10 are formed to make the cartridge 10
It also includes those in which the holder is held on the base 200.

Reference numeral 220 denotes a holding member that suppresses the movement of the cartridge 1o. be. Note that the presser member 22
0 shape - the number is not limited, for example, it has an opening slightly smaller than the outer shape of the cartridge 10, and the base 20
0, or a cover plate that is open at a portion corresponding to all or part of the exposure window 12, light shielding plate operation window 14, and central opening 13 of the cartridge 10. , can be designed in various ways.

Reference numeral 230 denotes a disk film rotation mechanism, and the illustrated one engages a retaining portion protruding from the upper surface of the recess 210 of the base 200 with the hub 21 of the disk film 20 exposed in the central opening 13 of the cartridge IO. , rotated (including reversing) by a motor or the like.

The disc film rotation means 230 may include a manual operation such as rotation of a lever or knob instead of a motor.

Reference numeral 240 denotes a supplying means for a developing processing solution, and the one shown in FIG.
Adapters 242 @ 242 are prepared, and each adapter 242 has a cassette 243 containing a developing processing solution such as a color developing processing solution, a bleach-fixing processing solution, a washing alternative stabilizing processing solution, etc. ing. Although the chemical composition, concentration, temperature, etc. of the developing solution prepared in each cassette 243 are important factors for the developing process, they are not limiting factors in the present invention, and can be set in various ways. omitted. However, regarding temperature control, the heating means is placed on the base 200 side described earlier,
An adapter 24 that heats the entire cartridge 10 during development processing, or in addition to or in place of this.
It is preferable to prepare a heating means for the cassette 243 and supply a developing solution controlled at a predetermined temperature. In this case, it is also more preferable to preheat the entire cassette 243 before setting it in the adapter 242. .

Note that it is preferable that cleaning means be provided in the development treatment liquid supply means 240 by using one adapter 242 or by providing an independent supply port.

In addition, in the illustrated example, the developing solution (cassette) is guided to a predetermined position on the base 200 by the rotation of the turntable 241. A holding mechanism for the adapter 242 (cassette 243) that has the same function as that of the adapter 242, which does not use the turntable 241,
It also includes a type fixed at a predetermined position on the four parts 11 of 00.

In addition, for supplying the developing solution to the emulsion surface of the disk film 240 by the adapter 242, various methods such as single drop application, spraying, etc., which will be explained later in the example of the apparatus, can be applied.

A method of developing a disc film while it is housed in a cartridge using the illustrated developing processing apparatus will be described.

First, the cartridge IO containing the photographed disc film is placed in the recess of the base 200 with the exposure window 12 facing upward as shown in FIG.
0 restricts upward protrusion. At the same time as the cartridge 10 is set, the engaging portion of the rotating means 230 is set (Film 20 c7) 7, F 2117) I
J O part K m go;l! h 4 '-""Next, the heating means provided on the adapter 242 side is turned on, and the processing liquid in the cassette 243 attached to the adapter 242 is heated, and after reaching a predetermined temperature,
Cartridge lO through the exposure window 12 (and or the light shielding plate operation window 16, central opening 13)
A developing solution is supplied to the disk film 20 in O from the emulsion side.

Note that if the temperature of the developing solution decreases significantly due to supply into the cartridge 10, it is preferable to control the heating temperature slightly higher or to prepare a heating means on the base 200 side. During the color development process, the disk film roller 240 is rotated by the rotating means 230. When the disc film 20 is rotated within the cartridge 10, the color development on the emulsion surface is caused by the friction of the emulsion surface of the disc film 20 with an attached member inside the cartridge 10 or a sponge prepared at the lower end of the adapter 242. Shearing of the treatment liquid is performed.

When the color development process for a certain period of time is completed, the rotating means 230
operation is stopped, then the turntable 241 is rotated, and after the color developing solution remaining in the cartridge 10 is discharged and cleaning is performed, bleaching or a processing solution for bleaching stone is supplied, and the rotating means 230 is rotated. The operation is turned on.

Thereafter, development processing is performed by similar operations, and upon completion of the processing, the cartridge 10 is removed from the base 200.
By cartridge opener.

Alternatively, the cartridge 10 is manually destroyed and the disc film 240 is taken out and dried.

In addition, in the case of a method in which a conventional water washing process is performed without relying on water washing stabilization processing, the cartridge 10 may be destroyed and the disk film 20 taken out before washing and drying. The process can be automated in whole or in part, or can be performed entirely manually. When automating, the rotation of the turntable 241
Automatic control such as position control, temperature control of the processing liquid, supply/discharge control of the processing liquid, control of disk film rotating means, and time system W is performed.

Apparatus Example 6: In FIG. 8, 300 is a base, the upper surface of which is formed with a recessed portion for placing the cartridge 1O, and the lower surface of which is provided with the motor of the disk film rotation means 310 and the processing liquid discharge means 13. is available. Lever operation instead of a motor.

It also includes a system in which the disc film is rotated manually by rotating a knob via gears or pulleys.

Reference numeral 302 denotes a presser member, and in the illustrated example, the base end is fixed to the end of the base 300 via a hinge mechanism.
The other end is fixed to the base 300 with a fastener. Note that it is preferable that the periphery of the upper surface of the base 300 has a light-shielding and water-tight structure using a sealing material such as packing material.

The holding member 302 includes a sponge or the like having a light-shielding/liquid-transmitting function that connects the adapter 242 and the exposure window 12 of the cartridge 10.
A light shielding plate opening/closing means 350 for opening and closing the light shielding plate is provided. This light-shielding plate opening/closing means 350 opens and closes a light-shielding plate provided in the exposure window 12 portion of the cartridge 10 by operating a lever, and uses the same mechanism as the light-shielding plate opening/closing mechanism in a disk camera. is possible.

A turntable 341 is attached via a bearing member provided at the center of the holding member 302, and cassettes 343 for developing processing liquid are provided radially.

The turntable 341 rotates around the position of the bearing member, and the cassettes 243 are sequentially guided onto the adapter 342.

The sponge inside the adapter 342 also serves as a resistance member, and is used to prevent the disc film 20 from being exposed even when the light shielding plate of the exposure window 12 of the cartridge 10 is opened, and to prevent frictional contact with the emulsion surface. Instead of a sponge, a bundle of fibers or a cotton-like material can also be used.

Alternatively, the adapter 342 may be formed into a labyrinth structure to block light and allow only the processing liquid to pass through.

Furthermore, it is preferable to provide a safety mechanism so that the cassette 342 cannot be removed when the light shielding plate is in the open state.

The heating means is a turntable 3411L or a base 300.
The arrangement on the side is the same as in the case of the device example shown in FIG.

The developing process of the disc film using the illustrated apparatus is as follows:
It is almost the same as that shown in Figure 0.

Apparatus Example 7: This is carried out using the apparatus shown in FIG. 12. In this apparatus, a disk film cartridge 10 is inserted into the pocket, and if necessary, it is fixed with a lid, and as in the previous apparatus example, A means for rotating the disk film 310 by a motor or manually, a means for supplying the processing liquid by an adapter 342 and a cassette 343, and a means for discharging the processing liquid by means of an electric valve or a manually operated nick or plug are arranged.

Apparatus Example 8: In the above description of the apparatus examples shown in FIGS. 10 and 11, the photographic processing liquid is supplied by opening the light-shielding plate of the cartridge 10 and supplying the disk film 20 from the cassette through a sponge or the like. The emulsion surface of the cartridge 10 is directly coated or dripped, and the light shielding plate remains closed.
In some cases, the photographic processing liquid is injected into the cartridge through an opening that the cartridge has, but in the former case, in addition to coating and dripping, spraying can also be used. For example, as shown in FIG. It also includes an embodiment in which the cartridge 10 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 four parts. In such an embodiment, the cartridge IO is placed in the exposure window 1.
It is also permissible to arrange the disc film 20 so that the emulsion surface of the disk film 20 is on the lower side.

Apparatus Example 9: The device shown in FIG. 14 is an example in which a disc film is subjected to photographic processing by the immersion method, at least up to bleach-fixing processing without bleaching, while it is housed in a cartridge. It is.

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. 14, reference numeral 10 denotes a cartridge of a film unit containing a bi-colored disc film. The cartridge 10 containing a disc film 20 to be developed is first placed on a starting stand 130 and prepared. Ru. When the processing start switch is activated, the vertical movement rod 121 of the transport system 120 descends, the chuck 122 configured at its tip grabs the cartridge 10 using the central hole of the cartridge IO, and the rod 121 rises. Then, the rod 121 moves to the right in the drawing along the guide rail 122 and moves to the color developing tank CD.
When the rod 121 is lowered, the cartridge 10 is immersed in the color developing solution, and the photographic processing solution is poured into the cartridge 10.

For example, it enters the cartridge through a gap in the exposure window or 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, and moves to the bleach-fix tank BF.
The disc film is guided by the cartridge 10, subjected to bleach-fixing processing, and then sent to the cutting section 140, where 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 device example shown in Figure 1, the cartridge 10 is destroyed in the cutting section 140, but the cutting device may also be arranged 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. If the operation is as follows: ejecting and relocating the cartridge 10, it is possible to prevent corrosion of the cutting device and also to reduce the size of the entire device.

Further, in the illustrated example of the apparatus, 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) Cutting the entire periphery of the cartridge 10 using a cutting blade as shown in the figure; 1) For example, cutting the base end of the cartridge 10 on the exposure window 12 side and cutting the label side plate 18 and the opening side plate; 11, or a nail 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, various designs can be made, such as one using a rotating blade, and in addition to those that can be destroyed by hand, and those explained in other device examples below, cartridges such as Kodak opener model H etc. can be used as needed. It is also possible to use an opener.

When the above photographic processing is completed, the cartridge 1O reaches the finishing table 131, is released from the chuck 122 of the rod 121, and is dried for a certain period of time.

The configuration of the illustrated photographic processing tank is shown as a representative example, and is not limited to the one shown in the figure.
It also includes those having different tank configurations, such as those having a color developing tank CI], a bleaching tank 46BL, 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 10 after being bleached in the bleach tank BL.

Further, for example, in the one shown in Figure 1, the drying section does not necessarily have to be provided, and the disc film 20 on the finishing stand 131 may be taken out after the water washing process is completed and dried using a separately provided drying means. .

A chuck 121 that fixes the cartridge 10 to the tip of the rod 121 and transports it. The chuck mechanism of the conveyance system 120 using the start stand 130 and the finish stand 131 is as follows.
For example, the disk film supply device described in Japanese Utility Model Application No. 59-170845 can be used.

As an alternative to the chuck mechanism, the cartridge 10 may be placed on a plate, a net, etc. and transported, or a part of the cartridge 10 is gripped and transported, or various other mechanisms may be used. It is possible to design.

The entire conveyance system 120 is not limited to the 4R configuration shown in the figure, but can be designed in various ways, and
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 10 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 that the emulsion surface of the disk film will be damaged, so it is not necessary to rotate at a high speed.

Apparatus Example 10: This apparatus example, as shown in FIG.
The cartridge 10 is attached to a chuck mechanism 122 provided on a holding member held by a guide rail 123, and is attached to each photo processing tank along the guide rail 123. supplied to

To transfer the cartridge to the photographic processing tank for the next process, the guide rail 123 is moved up and down, and the guide rail 12

The cartridge 10 is held with the exposure window facing downward, and the portion slightly above the exposure window 12 is immersed in the processing liquid in the processing tank.

Device Example 11: In this device shown in FIG. 16, the cartridge 10 is held by a chuck mechanism provided at the lower end of a shaft 420 that moves up and down by the operation of a solenoid 410. A turntable in which a photographic processing solution is stored and a processing tank 430 having heating means is arranged (instead of using a turntable, arms may be arranged radially and the processing tank may be arranged at the tip)
is intermittently rotated by a motor to guide each photographic processing tank to the position of the cartridge 10. In place of the mechanism for raising and lowering the cartridge 10 using the solenoid 41O, a lifting mechanism may be provided on the turntable side.

When supplying at least one batch of photographic processing solution using a cassette, as shown in FIG. The photographic processing liquid can be squeezed out by pushing out the cartridge using air pressure as shown in Figure 18, or by squeezing the cartridge with a roll or suppression plate as shown in Figures 19 and 20. .

Apparatus example 12: This apparatus is shown in FIG. 21, and this apparatus has a cartridge 1 in which a photographed disc film is stored in a recess in the base.
0 is placed and the rotating shaft 510 is placed on the hub 21 of the disk film.
Photographic processing is performed while the disc film 10 is rotated by engaging a chuck portion formed at the tip of the disc film 10.

Each photographic processing solution is preferably prepared in a cassette 520 and mounted on the holder 521. A heater 522 is incorporated in the holder 521,
The temperature-controlled processing liquid is supplied into the cartridge through, for example, a window 14 for opening and closing the light shielding plate of the cartridge IO.

The processing liquid supply section of the holder 521 may also serve as an opening/closing mechanism for the light shielding plate.

On the other hand, a roller 530 is provided in the exposure window 12 of the cartridge 10 in a structure that is shielded from light by a light shielding member and is always attached downwardly by a spring or the like. It is configured to rub the surface.

The pusher bottle 540 is operated downward by, for example, a solenoid to push out the label side plate 18 through the hole 16 of the cartridge 10 shown in FIG. 4, thereby destroying the cartridge 10.

In this example of the apparatus, it is preferable to arrange a heater also on the base side.

Device Example 13: The device of this device example has a base 600 as shown in FIG.
The cartridge 10 containing the photographed disk fill is placed in the recess on the upper surface with the label side plate 18 facing upward.
The hub 21 of the disc film 20 is engaged with a chuck mechanism provided at the tip of a rotary shaft rotated by a motor 620, and the upper surface is fixed by an O. The photographic processing liquid is supplied to the recessed portion of the base 600 using a processing liquid cassette in which the photographic processing liquid is placed, preferably controlled by an electromagnetic valve or the like, and the entire cartridge IO is immersed in the photographic processing liquid.

Photographic processing is performed while the disc film 20 is rotated by a motor 620.

Preferably, the temperature of the photographic processing liquid is adjusted in the cassette state, or after the temperature is adjusted at the stage of being discharged from the cassette, and then supplied to the recessed part of the base 600, preferably in the base 600. A prepared heater controls the temperature of the processing solution during photographic processing.

The pusher bottle 630 is moved vertically by a solenoid, for example, and is moved through the hole 16 formed in the exposure window side plate 11.
The label side plate 18 is peeled off from the exposure window side plate 11. Peeling may be performed at any time after the fixing process is completed.

Device Example 14: The equipment of this device example is as shown in FIGS. 23 to 26.
A plurality of cartridges 10 containing photographed disc films 20 are simultaneously processed. A rotating shaft 71 that rotates the cartridge IO by a motor.
0, for example, as shown in FIG. 24, a locking member 711 is placed in one or more slits provided in the rotating shaft 710, and a rod 712 is inserted or screwed into the locking member 711. bulges out in the width direction and engages with the central opening of the disc film. To release the engagement, it is sufficient to simply pull out the rod 712 to free the locking member 711.

A simple fixing method is to form an attachment 720 with a soft material such as rubber as shown in FIG. You may also do so.

Further, an embodiment may be adopted in which at least the lower part of the one-rotation shaft 710 is formed of a soft material.

As shown in FIG. 26, a rotating shaft 710 is attached via a support member so as to be movable in the vertical direction, and the rotation of the motor is transmitted via various transmission means such as pulleys and gears.

The photographic processing solution is preferably prepared in a temperature-adjustable processing solution supply means in a cassette (740) or in a storage tank regardless of the cassette, and is prepared according to a predetermined photographic processing step by controlling, for example, an electromagnetic valve. The processing liquid is sequentially supplied in an amount corresponding to the number of disk films to be processed.

The advantage of this device example is that even one cartridge can be used.

Also, it is possible to process multiple items at the same time, for example.

Since it is only necessary to supply the photographic processing liquid in an amount corresponding to the number of objects to be processed up to the topmost position of the installed cartridge, this is advantageous in reducing the amount of photographic processing liquid.

Apparatus Example 16: Next, an apparatus example incorporating a cartridge destruction mechanism will be described with reference to FIGS. 27 to 29.

1, the label side plate 18 is inserted through the through holes 16, 16, and the label side plate 18 is pushed downward by breaking the bond with the exposure window side plate 11. Note that, instead of the arm mechanism, the pin 830 may be driven by using a solenoid or the like that linearly reciprocates in the vertical direction.

Further, the illustrated arm may be attached to the base 810 side, and may further include a mechanism that engages and peels off the tip of the label side plate 18 pushed out by the pin 830, and a mechanism that engages and peels off the tip of the label side plate 18 pushed out by the pin 830, and a mechanism that removes the end of the cartridge 10 by the cutter 840. Alternatively, a cutting mechanism may be provided at the joint between the exposure window side plate 11 and the label side plate 18.

When the washing process is completed, the cartridge destruction mechanism is activated to peel off the label side plate 18 as shown in FIG. When the chuck mechanism formed at the tip is activated to release the disc film 20, the disc film 20 naturally falls and is discharged to the outside through the guide path.

Margin photographic processing liquid Next, representative examples of color photographic processing liquid that can be used to develop the disc film according to the present invention will be described in detail.

In the present invention, each photographic processing solution is preferably provided in a cassette containing the amount necessary for photographically processing one disk film, but the amount is sufficient for photographically processing a plurality of discs. This does not exclude what is provided by.

Further, it is preferable that the photographic processing solution is set in the above-mentioned development processing film along with the cassette; however, the application of the present invention is not limited to this. It is not a specific requirement.

A color developing solution is a processing solution used in a color development process (a process of forming a color image, specifically a process of forming a color image through a coupling reaction between an oxidized form of a color developing agent and a color coupler). Therefore, in the color development processing process, it is usually necessary to include a color developing agent in the color developing solution, but color developing agents are incorporated in the color photographic material. The color developing agent contained in the 0-color developing solution, which may be treated with a developer or an alkaline solution (activator solution), is an aromatic primary amine color developing agent, and is an aminophenol-based and p-phenyrezine amine-based color developing agent.

The bleaching agent used in the bleach-fixing solution can be any type of bleaching agent. It is coordinated with metal ions such as iron, cobalt, and copper. Examples of organic acids used to form such metal complex salts of organic acids include polycarboxylic acids and aminopolycarboxylic acids.

These polycarboxylic acids or aminopolycarboxylic acids may be alkali metal salts, ammonium salts or water-soluble amine salts, specific examples of which include ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid,

The bleach-fixing solution contains a silver halide fixing agent in addition to the above-mentioned bleaching agent, and if necessary, a solution A[II&] containing sulfite as a preservative is applied. In addition, a bleach-fix solution consisting of an ethylenediaminetetraacetic acid iron (III) complex salt bleach and a small amount of a halide such as ammonium bromide other than the above-mentioned silver halide fixer, or conversely, a halogen such as ammonium bromide may be used. There are bleach-fix solutions with a composition in which a large amount of chlorides are added, and even special bleach-fix solutions with a composition consisting of a combination of an ethylenediaminetetraacetic acid iron(m) complex salt bleach and a large amount of a halide such as ammonium bromide. Sometimes used. In addition to ammonium bromide, the halides include hydrochloric acid, hydrobromic acid, lithium bromide, sodium bromide, potassium bromide,

Furthermore, the bleach-fixing solution is disclosed in Japanese Patent Publication No. 46-280, Japanese Patent Publication No. 45-8506, Japanese Patent Publication No. 46-556, Belgian Patent No. 770,910, Japanese Patent Publication No. 45-8836, Japanese Patent Publication No. 53-9854, Japanese Patent Application Publication No. 5
Various bleaching accelerators such as those described in No. 4-71634 and No. 49-42349 may be added.

The pH of the bleach-fix solution is used at 4.0 or higher, but it is generally used at a pH of 5tO or higher and 9.5 or lower, preferably at a pH of 8.0 or higher and 8.5 or lower, and more preferably at a pH of 6.0 or higher. Processed at 5 or more and 8.5 or less.

Note that the bleach-fixing process may be performed separately into a bleaching process using a bleaching solution containing the above-mentioned bleach as a main component and a fixing process using a fixing solution containing the above-mentioned fixing agent as a main component.

The water-washing alternative stabilizer is not a normal stabilization process but a water-washing alternative, and refers to image stabilization processes such as those described in Japanese Patent Application Laid-Open No. 58-134636, as well as Japanese Patent Application No. 58-2709, etc. This is to essentially eliminate the need for water washing. Therefore, the name of the treatment bath does not necessarily have to be stabilization treatment.

There are also stabilizers that have the function of stabilizing color images and those that have a draining bath function that prevents contamination such as uneven washing. These stabilizers also include coloring adjustment liquids for coloring color images and antistatic liquids containing antistatic agents.

The above treatment was carried out individually using the following treatment liquid supply method. 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 light-shielding plate of the C1 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.

As a result of the above processing, the occurrence of scratches on the emulsion surface, development unevenness, and Dmax were investigated and the results were as follows.

Problems Development unevenness Dmax A Δ Oo B Δ 0O coo.

D　　Δ　　o.

EOO0 FOOΔ~0 0 is equivalent to the standard processing data, Δ is inferior to the standard processing data, but there is no problem in terms of photographic performance.If the sample disk film is rotated in the cartridge, scratches can be seen on the emulsion surface. This is because it does not affect the photographic performance of the object and meets 1 or more.

It has been found that equivalent photographic performance can be obtained with a much lower rotation speed than the standard processing speed.

Experimental Example 2: G. Open the light-shielding plate of the cartridge, insert a roller through the exposure window, and apply the color development processing solution to the emulsion surface.The color development processing in Experimental Example 1 was carried out at a processing temperature of 40°C and a processing time of 2 minutes and 45 minutes.
The rotation speed of the disc film was changed to 10 rpffi.

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

A color development processing solution is supplied to the emulsion surface by spraying.

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.

■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 drain the processing liquid inside the cartridge and supply the processing liquid for the next process. I did it like that. Experimental example 1
The color development treatment described above was performed 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 10 rpm.

Experimental example 3: Rotating the disc film while it is stored in the cartridge (
The processing times were compared between one in which the film was developed at a speed of 10 rpm (10 rpm) 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 in 3 minutes with the method that processes while rotating, but with the method that does not rotate once, it took 6 minutes to process. Uneven development occurred.

In the case of a method in which the processing liquid is oversupplied and stored around the cartridge, no uneven development occurred in the rotating type, which lasted 2 minutes and 45 seconds.

In the case where rotation was not performed, uneven development occurred after 6 minutes of processing.

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 in a 3-minute process using one revolution, but a method that does not involve one revolution 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 using a sponge that did not rotate once.

Experimental Example 5; Next, by changing the rotation speed of the disc film, the Blue port Ila! 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 I1ma Violet Scratch Graininess (RP layer) 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 Slight occurrence ++ Based on the above, if you constantly supply new processing liquid, processing stability can be improved and processing time can be shortened, and it is also possible to process while rotating the disk film. It has been found that this method has the advantage that uneven development is less likely to occur, and that scratches can also be prevented if the rotational speed is appropriately set.

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 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 for 3 minutes and 15 seconds at a solution temperature of 38℃, 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 processing time was 3 minutes, and the number of revolutions was 1 Orpm, 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 in the cartridge can produce photographic images equivalent to those of the conventional method, and is also superior in shortening the processing time.

Experimental Example 7: Sensitometry was performed on the disc film used in Experimental Example 6, in which stepped exposure was performed, the cartridge was destroyed after fixing BL processing, and subsequent processing was performed. As a result, the maximum density D wax was as follows.

Regular one layer is 2.8 to 3.0. Ortho residence is 2,2~2
．． 3. The panchromatic layer was 1.8-1.9.

Experimental Example 8: As a method for supplying photographic processing liquid into the cartridge, the processing liquid temperature was 38°C to 40°C by dipping, injection from the cartridge opening using a cassette, roller coating, spraying, and hole injection. .5℃, and the disc film for each in a bright room
A development process was performed at an rpm of 3 minutes, 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. Since the emulsion surface was not scratched, it was demonstrated that it is possible to process the disc film in the cartridge in a bright room.

Experimental example 9: Using sample disk film, supplied processing liquid temperature 38℃1

the result.

Regarding A and B, there are no scratches, and regarding C and D, there are slight scratches, but there are shadows on the screen! For E and F, scratches occurred but did not affect the screen, and for G and H, the scratches were large and gave the screen 1g. From the above experiments, It has been found particularly advantageous to release the cartridge after BLL 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 conducted in which color development CD processing was followed by bleach-fixing without BF processing. Regarding development, it was found to be particularly favorable. In Experimental Examples 9 and 10, a mechanical method using a cartridge opener and a manual method for releasing the cartridge were compared, but no shadows were observed in the images.

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 process was carried out at a liquid temperature of 38°C for 3 minutes and 30 seconds, and the present invention was processed at a liquid temperature of 38°C for 3 minutes, and at a liquid temperature of 55°C for 1 minute, bleached BL, fixing FIX. Each stable SST treatment was 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 present invention at 38°C.
There was no difference between the 3-minute treatment and the 1-minute treatment at 55° C., and graininess superior to both was obtained.

From the above experiments, the processing method according to the present invention not only shows no difference in photographic areas compared to conventional processing methods, but also has the advantage of short processing times. Furthermore, high-temperature processing reduces the time9.
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 3 rotations per rotation
The experiment was conducted at 0 rpta and a developing time of 3 minutes and 15 seconds.
In addition, the rotation speed of the standard processing one is 20 O rpm,
Dmax was set to 100.

1 0 1 This experiment shows that the effect of the resistance member on processability is remarkable, and due to the presence of the resistance member, sufficient images can be obtained even when the disk film is rotated at low speed! It was found that the concentration could be obtained.

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 processing apparatus of the present invention, the following advantages are achieved: speedy processing, miniaturization of the apparatus, ease of operation, improvement in the quality and stability of photographic performance, and reduction in the amount of photographic processing solution. It is useful to achieve the stated purpose, especially.

Processing stability and sharpness are improved because the permeation speed of the processing liquid on the emulsion surface of the disk film is increased, and even at low rotation speeds, processing stability and sharpness are improved compared to the conventional method of simply rotating. In addition, by using the wall surface of the processing tank as a resistance member, it is possible to reduce the amount of processing liquid and the size of the device.
