Description

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

(Conventional technology) Wanting to see the photo as soon as it is taken is an insatiable desire, and the things that have made this possible include the Polaroid company of the United States, which is famous as Polaroid, and -11 instant photography. Among the recent hot topics are electronic ones 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 obtaining multiple prints, while the latter is currently not fully satisfactory in terms of photographic properties 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. Although it discloses a novel photographic processing system that allows viewing of ti shadow images, the prior art for understanding the present invention is as follows.

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

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

Regarding photographic (processing) technology using disc film,
Although many conventional roll film technologies have been repurposed,
For example, regarding O-disc film cameras, there are U.S. Pat. Regarding O-disk films and film units, see U.S. Patent No. 4212673, U.S. Patent No. 4264169, JP-A-53-113525, JP-A-55-101940, JP-A-55-101942, and photographs of O-disc films. For processing, US Pat. No. 4,112,453.

No. 08116, U.S. Pat. No. 4,248,564 for printing with O-disc film.

U.S. Patent No. 4,203,664; U.S. Patent No. 4,204,773; Regarding O in general.

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

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

[Problem that the invention seeks to solve]

Disc film, like other amateur photography films such as 35mm roll film, is protected from light by being stored in a light-tight container (hereinafter referred to as a cartridge).
When shooting, the cartridge is attached to the dedicated camera. The dedicated camera has a cartridge installed and winds up (cue)
The shutter of the exposure window of the cartridge is opened in conjunction with
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 mentioned above, the development process for such a disc film involves destroying the cartridge in a dark room using a cartridge opener prepared separately from the developing processing device, taking out the disc film, storing it in a special carrier, and processing it. The process of color development, bleaching, fixing (or pre-bleaching), and washing (or stabilization) is carried out virtually in a dark room, just as in the case of roll film. is the actual situation, so the entire outfit has become larger,
The operation is also complicated. In addition, darkroom processing is required, so
Another drawback is that it takes time to respond in the event of a failure.

In addition, conventional processing equipment has the advantage of being able to process a large number of sheets at once - 1 Disc film consumers in Japan are amateur photography film (mainly 35m roll film, which accounts for only 3%, 1 The amount of developing processing received at the Hino Kame store is extremely small, only a few sets - 0 cassettes, forcing intensive processing by laboratories as mentioned above. This results in turning its back on the needs of the consumer side, such as shortening the processing (waiting) time, which takes one day or even several hours or even an hour from reception to delivery.

Furthermore, in laboratories, a large number of disk films are automatically processed, so it is practically difficult to process a specific small number of disks particularly quickly.

In addition, laboratories are installed in uneven locations, and as long as photographic processing is carried out by teleportation, it is not possible to satisfy the desire for immediate visual inspection after the m-image. Therefore, in order to satisfy this desire, it is necessary to go to a nearby place other than the laboratory, such as a camera store,
It is desired to enable photographic processing at conventional DPE distributors, film retailers, etc., and furthermore, to enable in-house processing.

On the other hand, developing processing equipment that can process such a large number of sheets at once is
The processing tank is unnecessarily large, there are large fluctuations in the amount of processing liquid, temperature, etc., and there is also the effect of eluates from continuous processing, which not only has a large impact on photographic performance, but also requires a replenisher tank and processing liquid replenishment device, Because it is equipped with a waste liquid tank or flush water piping, etc., the entire device is unnecessarily large, and its operation is complicated and requires a certain level of specialized knowledge, including how to operate it in a darkroom in case of trouble, so it should not be installed at a camera store. This prohibits in-store processing services and goes against the goal of shortening processing (waiting) time. The 35TS roll film is water-free, piping-free, table-sized, and allows for quick processing (within 1 hour) in-store service.Responding to the trend toward minilabs, photo processing equipment manufacturers are using disc film or disc film. camera is 35m
This offsets the advantages of roll film or cameras, such as ease of operation, ease of handling, compact size, and ease of organizing til-imprinted film, and hinders the spread of disc film. This creates a vicious cycle.

In recent years, as electronic devices such as videos have become widespread, people are no longer satisfied with just looking at prints as they used to be, but there is a strong desire to view prints on large screens such as televisions with a large number of people, including family members.
Rapid advances in electronic equipment in recent years have made it possible to electronically read out color image information from developed films, making it possible to 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 film without printing, and compared to conventional simultaneous printing systems, the development process is reduced by eliminating the printing process. will be exactly half that amount. This brings us one step closer to the original desire to view images as soon as possible, but the more this happens, the stronger the demand for shortening the processing (waiting) time, and the need for in-store processing services and even in-house processing. There are even demands for 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 sufficient to be able to process at most one or two sheets at a time, and 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., there are no buttons). (or no need for complicated darkroom operations).

In conventional automatic processing machines, the photographic processing solution is discharged from the processing tank by overflowing by newly supplying replenisher, but it is expected that the photographic processing solution will be distributed at various locations. In consideration of the delivery of photographic processing liquid, the treatment of photographic processing waste liquid (overflow liquid), etc., it is desirable to be able to carry out photographic processing with a small amount of developing processing liquid including washing water.

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

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

In view of the above-mentioned problems, the present invention has been achieved as a result of intensive research. 1. The present invention substantially eliminates the use of a photographic processing tank and allows photographed discs to be stored in cartridges. The main purpose of this paper is to clarify a method for developing a disc film in which the film is developed by supplying a photographic processing liquid to the film using an opening provided in the cartridge itself.

[Means to solve problems]

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

That is, a developing processor having no substantially light-shielded portion holds the cartridge 2 in which the photographed disc film is stored, and photographs the disc film while it is stored in the cartridge. It is something.

Cart Fujis used in the present invention include those currently used in reprint disc cameras and those improved in the future, and are not particularly limited.

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.

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 disk film rotation mechanism, a temperature adjusting means, etc., which will be described later, and is not limited to the above.

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.

In addition, processing efficiency is improved by one rotation, and compared to one without rotation, processing time is not only significantly shortened, but also the graininess of the image is improved.

As a mechanism for rotating the disc film.

It is preferable to provide a rotating shaft that is rotated directly by a motor or via a drive transmission mechanism, and to rotate the disk film by engaging the rotating shaft with the hub of the disk film through the disk core.

The rotation of the disk film is relative, and the cartridge can be removed by pressing the outside of the cartridge with a pressing means such as a stopper, or by forming a recess in the base and storing the cartridge in the recess. The disk film may be fixed so as to rotate, or conversely, the disk film may be fixed so as not to rotate and the outer cartridge may be rotated.

Various methods can be used to supply photographic processing liquid to the disc film surface, such as injection, dripping, coating, and spraying. It is arbitrarily selected according to the method of holding the cartridge, the structure of the cartridge destroying means, the structure of the processing liquid, etc.

Furthermore, the end face of the cartridge and the opening of the part where the processing solution is not supplied or discharged may be covered with tape or the like to prevent leakage of the supplied photographic processing solution. It may also serve as a means for preventing leakage of the processing liquid.

Conveyance of the cartridge in the photographic processing process, that is, means for moving the held cartridge vertically, horizontally, circumferentially, etc., and transferring it to each processing tank can be carried out by various known means.

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

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 device, and furthermore, in the processing device, the processing liquid (cassette) is selected and applied directly to the disk film surface, or preferably to the processing tank. Preferably, a treatment liquid is supplied.

It is preferable that the processing equipment is provided with a temperature adjustment means to ensure a stable processing temperature, and the type, shape, installation (position 1 heat generation capacity, heat transfer method, etc.) of the heater in this temperature adjustment means are limited. However, it is preferable to keep in mind the following points: The processing liquid has a high specific heat and a low heat transfer coefficient compared to (metallic) holding devices, etc., so it should be preheated and kept warm. The temperature of the processing liquid during processing tends to be influenced by the temperature of the cartridge and disk film, so it is preferable to adjust the temperature of these and the surrounding space or members before or during processing. .

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. The operation to make the image into fine particles is also part of the process.

Preferably, the processing equipment is provided with drying means.

In the case of a method in which the disc film is removed from the cartridge and dried, it may be dried naturally.

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

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

Any means for destroying the cartridge may be used as long as it does not damage the disc film; a 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, it is preferable to rotate the film during the drying process.
Rotation allows water droplets on one surface to be brushed off, increasing the drying speed. 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
The peace of mind provided by bright room treatment, which is preferably performed after CD, is greatest at this time. That is, as the cartridge goes through the processing steps when it is broken and the film is exposed.

This is because the image gradually appears clearly on the disk surface.

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

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

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

It is preferable that the processing apparatus 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, the waste liquid is 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. In this case, it is also more preferable to mix a deodorizing material such as activated carbon to absorb the malodorous components.Also, it is preferable to mix in a deodorizing material such as activated carbon to absorb the malodorous components. It is also preferable to reduce the amount of waste liquid to be discarded by evaporating water in the waste liquid and concentrating or drying the waste liquid.

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

(Left below) [Example] Next, an example of a specific apparatus for carrying out the disc film development method of the present invention will be described in detail with reference to the accompanying drawings.

It should be noted that the present invention is not to be construed as being limited by the specific examples shown in the drawings; the specific examples shown in the drawings are merely examples, and the details may be rearranged with other devices shown in the drawings, or equivalent devices not shown in the drawings may be used.

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.

Traditionally, the photographed disc film unit was sent to the laboratory through a distributor;

First, the cartridge 1O is destroyed in a dark room using a special cartridge opener, and the disc film 20 is taken out. To destroy the cartridge 10, basically, the cartridge destruction openings 16, 16 provided in the exposure window side plate 11 of the cartridge 2 10 are used.
This is done by inserting a pin through the opening, pushing out the label side plate 17, and breaking the joint between the exposure window side plate 11 and the label side plate 18. In addition to this basic operation, the end of the cartridge 10 may be cut off, and the end of the label side plate 18 may be pushed out or pulled.

Reference numeral 230 denotes a disk film rotation mechanism, and the one shown in FIG. , 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 developing solution supply means, and in the illustrated one, a plurality of developing solution supplying adapters 242, 242 are prepared on a turntable 241, and each adapter 242, 242 is provided with a color developing solution. Developing processing solutions such as a processing solution, a bleach-fixing processing solution, and a washing alternative stabilizing processing solution are stored in a cassette 243 and prepared. 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 20O side as explained earlier,
An adapter 24 that heats the entire cartridge 1O 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 an adapter 242 (cassette) 243) having the same function as the turntable 241;
It also includes a type in which the turntable 241 is not used and the adapter 242 is fixed at a predetermined position on the recess 11 of the base 200.

In addition, various methods such as injection, coating, dripping, and spraying, which will be explained later in the embodiments, can be used to supply the developing solution to the emulsion surface of the disk film 240 using the adapter 242.

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 on the four parts of the base 200 with the exposure window 12 facing upward, as shown in FIG.
This restricts the upward protrusion. At the same time as the cartridge 10 is set, the engaging portion of the rotating means 230 is engaged with the opening of the hub 21 of the disk film 20.

Next, the heating means prepared on the adapter 242 side is turned on, and the cassette 2 attached to the adapter 242 is heated.
After the processing liquid in the cartridge 10 is heated and reaches a predetermined temperature, the disk film in the cartridge 10 is passed through the openings (exposure window 12, light shielding plate operation window 16, central opening 13, etc.) provided in the cartridge 10 itself. A developing solution is preferably supplied to 20 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 emulsion surface of the disc film 20 rubs against the alignment member inside the cartridge 10 or the sponge provided at the lower end of the adapter 242, causing color development on the emulsion surface. Shearing of the treatment liquid is performed.

When the color development process for a certain period of time is completed, the rotating means 230
The operation of the rotating means 230 is stopped, and then the turntable 241 is rotated, and after the color developing solution remaining in the cartridge 10 is discharged and cleaning is performed, a bleaching or bleach-fixing processing solution 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.
The cartridge 10 is destroyed by a cartridge opener or manually, 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 IO 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 the disk film rotating means, and time control is performed.

Example? = This is carried out by the apparatus shown in Fig. 2, in which 300 is a base, the upper surface of which is formed with four parts on which the cartridge 10 is placed, and the lower surface formed with the rotating disk film. A motor for the means 310 and a processing liquid discharge means 13 are provided. It also includes a device in which the disk film is rotated by manual operation by operating a lever or rotating a knob via a gear or a boolean instead of a motor.

Reference numeral 302 denotes a holding member, which is not shown in one figure.

The base end is fixed to the end of the base 300 via a hinge mechanism, and 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 is the same mechanism as the light-shielding plate opening/closing mechanism in a disk camera. It is possible to use

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 is provided to prevent the disk film 20 from being exposed even when the light shielding plate of the exposure window 12 of the cartridge 10 is removed, and to make rubbing 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.

Providing the heating means on the turntable 341 and/or the base 300 side is the same as in the embodiment shown in FIG. 7.

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

Example 3: This is carried out using the apparatus shown in FIG.
Insert the disc film cartridge 10 into the pocket and fix it with a lid if necessary. Similarly to the previous embodiment, the processing liquid is supplied by the motor or manual disc film rotating means 310 and the adapter 342-cassette 343. A supply means and a discharge means 320 for discharging the processing liquid using an electric valve or a manually operated nick or stopper are arranged.

In the apparatus described above, the supply method of the photographic processing liquid is as follows:
The light-shielding plate of the cartridge 10 is opened and the emulsion surface of the disc film 20 is directly coated or dripped from the cassette through a sponge, etc., and the light-shielding plate remains open and the emulsion is applied from the opening of the cartridge 10. In some cases, the photographic processing liquid is injected into the cartridge, but in the former case, in addition to coating/dropping, it is also possible to spray it. In the latter case, for example, as shown in FIG.
It also includes an embodiment in which the recess is formed slightly deeper than the thickness of the cartridge 10 so that the processing liquid overflowing from the cartridge 10 is collected in the recess. In such an embodiment, cartridge 1
0 so that the exposure window 12 is on the lower side, and the emulsion surface of the disk film 20 is on the lower side.

Figures 5 to 8 show an example of a supply mechanism for supplying at least one batch of photographic processing solution using a cassette. , the photographic processing liquid inside the cartridge is pushed out from the rear end by a suppressing mechanism such as a solenoid. Figure 6 shows extrusion using air pressure, and the ones shown in Figures 6 and 7 use a roll, suppressing plate, etc. The cartridge is squeezed to squeeze out the photographic processing solution.

Embodiment 3: This is carried out using the apparatus shown in FIG. 9, in which a cartridge 10 containing a photographed disc film is mounted on the four parts of the base, and a rotating shaft 510 is mounted on the hub 21 of the disc film.

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, an experiment was conducted 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 or cartridge, a good image with no uneven development was obtained in 3 minutes with the method that processed while rotating, but with the method that did not rotate, it was possible to obtain a good image with no uneven development.
Uneven development occurred after processing for 1 minute. - 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 only takes 6 minutes to process. Uneven development occurred.

Even with a supply method in which the processing liquid is immersed in the cartridge, for example, up to a slightly upper part of the exposure window, a good image with no uneven development was obtained in a 3-minute process with a rotating cartridge, but it is not possible to implement a cartridge without rotating.

Similarly, when applying with a sponge or the like, a good image was obtained in 2 minutes and 30 seconds using a rotating method, but it was impossible to apply using a non-rotating method.

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

When the Blue Dmax arrival time, the occurrence of scratches on the emulsion surface, and the graininess were tested, the following results were obtained.

Rotation speed BLLIHD+*ax Scratch Graininess (RP layer) 1 3 minutes 45 seconds None -1o
3 minutes None +30 2 minutes 4
0 seconds None ++50 2 minutes 35 seconds
Occurs a little ++100 2 minutes 30 seconds Occurs a little +10 From the above, it is possible to improve the processing stability and shorten the processing time by constantly supplying new processing liquid. Processing while rotating reduces the occurrence of uneven development.
It has been found that setting the rotation speed appropriately has the advantage of preventing scratches.

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

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

Conventional equipment that rotates disk film
There were no scratches during the color development process for 3 minutes and 15 seconds at a solution temperature of 38℃, but uneven development occurred.
After 5 seconds of processing, neither uneven development nor scratches occurred.

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 10 rpm, and the results were the same as those of the conventional method in which the disc 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, the cartridge was destroyed after fixing BLL processing, and subsequent processing was performed.As a result of sensitometry, the maximum density Dwax was as follows.

Regular one layer is 2.9 to 3.0. Ortho layer is 2.2-2
．． 3. Panchromaticity was 1.8 to 1.8.

Experimental Example 8: The photographic processing solution was supplied into the cartridge using 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. .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
Color development CD processing 3 minutes 15 seconds, bleaching BLL processing 6 minutes 30 seconds, fixing FIX processing 3 minutes 15 seconds, stable SST processing 4 minutes 30 seconds

the result.

Regarding A and B, there are no scratches.

Regarding C and D, slight scratches occur, but they do not affect the screen.

Regarding E and F, scratches occurred but did not affect the screen, and regarding G and H, the scratches were large and did not affect the screen.

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, one color development CD treatment was followed by bleaching constant i.
After experimenting with a method that performs BF processing, it was found that releasing the cartridge after the completion of bleach-fixing and 17BF processing was particularly preferable in terms of the occurrence of scratches on the emulsion surface. In addition.

In Experimental Examples 9 and 1O, a mechanical method using a cartridge opener and a one-manual method for releasing the cartridge were compared, but no effect was observed on the image.

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

Note that this is for one-color development CD processing using a conventional device.

Processing time: 3 minutes and 30 seconds at a liquid temperature of 38°C. 1. 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, and stable SST. Each treatment was performed under the same conditions. As a result, there was no difference in processing unevenness, and in terms of graininess, the conventional method and the present invention showed
There was no difference between the 3-minute treatment and the 1-minute treatment at 55° C., and the graininess was better than both.

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 3
The experiment was conducted using Orpm and a development processing time of 3 minutes and 15 seconds. In addition, the number of rotations for standard processing is 20 Orpm, Dma
x was set to 100.

Distance (am) Dmaxlo
30 0.5. 101 From this experiment, it was found that the resistance member has a remarkable effect on processability, and that sufficient image density can be obtained even when the disk film is rotated at a low speed due to the presence of the resistance member.

Experimental Example 13: A case in which a photographic processing solution is stored in a synthetic resin material 1, such as polyethylene phthalate, and a container having a shape corresponding to the illustrated processing tank or recess is used as a processing tank. 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 disc film development method of the present invention, there is no need for a large processing tank like in the past, and there is no need for darkroom equipment, so it is useful for downsizing and simplifying the packaging 2.
Since the development process is performed using the processing liquid supplied into the cartridge, there are few fluctuations in processing conditions, resulting in stable and easy processing. It is possible to solve important problems such as ease of use, improvement in the quality and stability of photographic performance, and reduction in the amount of photographic processing solution and waste liquid.

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