Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to at least one disk film (meaning a disk-shaped photographic material supported by a core, which is housed in a cartridge with a light-shielding structure, The present invention relates to a developing machine that performs processing on a developing unit (configured in a unit). More specifically, the present invention relates to a developing machine that is equipped with a cartridge containing a photographed disk film for processing.

[Prior Art] Conventionally, photographed disk film is sent to a central processing facility called a laboratory through a DPE distributor to be processed while being stored in a cartridge. In a laboratory, the disk film is first removed from the cartridge using a cartridge opener with a dark room structure, then a large number of disk films are transferred to a magazine, and the magazine is then set in a large automatic developing machine and processed.

To remove the disk film from the cartridge, in addition to a cartridge opener system for processing a large amount of the disk film, an opener for processing a small amount of the disk film is also known. In either case, however, the apparatus is quite large.

[Problems to be Solved by the Invention] In the case of roll films, the spread of small automatic developing machines called minilabs has made it possible to wait for printing to be completed for one hour.

On the other hand, in the case of disk film, processing facilities are unevenly distributed, so it is still common to have to wait a full day for printing. For this reason, despite having many advantages, disk film has not become popular, and because it is not popular, a dilemma has arisen in that the processing waiting time cannot be shortened.

The work of taking out the disc film from the cartridge and the developing process must be done in a dark room.
Therefore, many difficulties must be overcome in order to enable developing services to be provided at DPE distributors and the like that do not have darkroom facilities.

As one of the solutions, it has been proposed to develop the disc film while it is stored in the cartridge. Various problems remain to be solved before practical use, such as how to extract them from the equipment and what is the optimal configuration for miniaturizing these devices.

In view of the above, the main purpose of the present invention is to clarify a simple developing machine that processes at least one disk film and does not require a separate cartridge opener. Furthermore, the purpose of the present invention is to clarify a developing machine in which it is easy to supply and discharge the processing liquid into the cartridge, and in which processing errors such as uneven development do not occur.Other objects and benefits of the present invention are as follows. This will become clear from the description and the attached drawings.

[Means for Solving the Problems] The above-mentioned object of the present invention is to provide a space in which a film unit in which a photographed disk film has been stored in a light-shielded state is set as is, and which is connected to the disk film rotation means described below. a processing chamber in which a joint end, an operating member for a cartridge opener, a guide port and a discharge port for a processing liquid supply means are prepared;
This lid keeps the processing chamber closed and watertight and light-tight, and has a stopper that locks both ends of the exposure window side plate of the cartridge of the film unit. While locked by the stopper provided on the side of the body, operate the operating member to project it into the processing chamber and press the end of the label side plate of the cartridge so that the cartridge forms a V-shape when viewed from the side. A cartridge opener to be destroyed, a means for supplying the processing liquid prepared in a syringe-shaped container for each processing liquid into the processing chamber, and a rotational force of the motor being applied to the disk film through an engaging end protruding into the processing chamber. It consists of a rotating means for rotating the disc film stored in the cartridge by transmitting information to the central core, and the disc film stored in the cartridge in a light-shielded state is set as it is and is developed in a bright room. This is achieved by a developing machine for disk film, which is characterized in that it is configured to.

One of the preferred embodiments of the present invention is to have a means for vibrating the disk film and/or the processing liquid instead of or in addition to the means for rotating the disk film.

The details of the present invention will be explained below with reference to the accompanying drawings.

In FIGS. 1 and 2, 10 is a frame;
By closing the lid body 20 using the stopper 30, a watertight and light-shielding processing chamber 40 is formed. A processing liquid is supplied to the processing chamber 40 through a guide port 51 by a processing liquid supply means 50, and after a certain period of processing, the waste liquid is passed through a discharge pipe 5 guided from the processing chamber 40.
It is discharged to the outside through 2. Reference numeral 60 denotes a motor, and an engaging end 61 protruding into the processing chamber 40 engages with a central core 72 of a disk film 71 in a film unit 70 shown in FIG. 3 to rotate the disk film 71 during processing. . Instead of the motor 60, the disc film may be rotated manually. It is also preferable to vibrate the disk film and/or the processing liquid instead of or simultaneously with the rotation.
Vibration is performed by placing a vibrator in the processing chamber 40 and vibrating the disk film directly, by vibrating the processing solution, by placing the entire developing machine shown in the figure on a vibration table, etc., and the vibration frequency is in the low frequency range. It is also preferable to use ultrasonic waves.

The base end 74 of the label side plate 73 and both ends 76, 76 of the exposure window side plate 75 of the attached cartridge.
are fixed by stoppers 21 and 22 provided on the lid 20, respectively.

An opener 80 projects into the processing chamber 40 and presses both ends of the label side plate 73 through openings 78, 78 provided in the center end 77 of the label side plate 73 and the exposure window side plate 75 of the cartridge to be loaded. This pressing member 81
and an operating member 82 for operating the.
As shown in the figure, the base of the operating member 82 is attached to a bearing fixed to the frame 10, and when rotated in the direction of the arrow, the pressing member 81 is projected by the principle of leverage. At this time, if the cartridge is set in a predetermined position, the exposure window side plate 75 is prevented from moving by the stoppers 22, and only the end of the label side plate 73 is pressed by the pressing member 81, so both plates are pressed. The joint that joins the cartridges is destroyed, leaving the cartridge in an open V-shape. Although not shown, if a locking means for fixing the operating member 82 is provided, the cartridge can be maintained in the V-shaped open state.

FIG. 4 shows a pressing member 8 using a motor 60.
1 is shown. That is, a screw 83 is provided in a straight line with the pressing member 81, and by rotating the gear 84 provided on this screw 83 by the motor 60, even a motor with a small torque can destroy the cartridge with a large force. It becomes possible.

Note that some commercially available disk film units have different ways of joining the two plates that form the cartridge, making it difficult to separate the cartridge plates using only a peel-off type cartridge opener as shown in Figure 1. There is something. In the case of this type of cartridge, as shown in FIG. 5, for example, in addition to the above-mentioned peel-off type cartridge opener, or alone, a blade 85 that moves linearly along the joint of the cartridge is used. It is preferable to do so.

To advance the blade 85, it may be possible to simply press the blade 85 linearly, but it is preferable to rotate the screw 86 and push the blade 85 linearly using the guide 87 without rotating it.

In the illustrated configuration, the processing liquid is preferably supplied using a syringe-shaped container 53 prepared for each processing liquid, and by manually pressing a piston, the stored processing liquid is passed through the guide port 51 for processing. It is supplied to chamber 40. The amount of processing liquid supplied may be such that the exposure window of the cartridge set in the position shown in FIG. 3 is immersed.

Processing liquid is supplied to the processing chamber 40, and since the cartridge is kept open in a V-shape, a larger amount of processing liquid reaches the image area of the disk film than when the cartridge is not opened. Processing performance can be improved by rotating the disk film.

The treated waste liquid is discharged to the outside using the discharge pipe 52, but it is also preferable to provide the discharge pipe 52 with a valve or to forcefully discharge it using a suction pump or the like.

As the processing liquid supply means 50, various embodiments can be adopted in addition to the configuration shown in the drawings.

[Effects of the invention] According to the developing machine of the invention, it is possible to easily develop the photographed disk film stored in the cartridge by simply setting it, and the processed disk film can be easily processed. Since it can be easily taken out from the cartridge by hand and the developing process of the disc film can be carried out quickly even in a place without dark room equipment, the above-mentioned purpose can be achieved.
