Description

Detailed Description of the Invention (Technical Field of the Invention) The present invention relates to a processing device for developing, fixing, or washing a roll photographic film. The present invention relates to a photographic film processing apparatus that holds a film according to its width and performs development, fixing, or water washing only on the photosensitive side of the film when processing a general photographic film.

(Technical background of the invention and its problems) FIG. 6 is a cross-sectional diagram schematically showing a developing machine in a photographic film processing apparatus using a general roller conveyance processing method, in which photographed photographic film l is The loading port 30 is connected to the rotor group 31A, 118 which is mounted between the opposing side plates.
It is carried in from A, is developed in the developer (D), and after the developer (D) adhering to the photographic film l is squeezed out by the squeeze roller 31B at the final stage of the developing section, it is transported from the exit 30B to the next -r stage. (fixing process). Conventionally, most automatic developing machines use this roller conveyance processing method because the developing performance is stable and the processing speed is relatively fast. However, even in this roller conveyance processing method, many rollers are used, so if the developer that adheres to the rollers crystallizes, uneven development will occur, which is not only a sight to behold, but may also damage the photographic film 1. be. Therefore, this roller must be removed frequently for maintenance such as cleaning, which poses a disadvantage of placing a heavy burden on the operator. Also, there are films that are processed on both sides, such as X-ray film, but with ordinary photographic film, only one side (the photosensitive side) needs to be processed, but since the developer is deposited on both sides, there is a lot of extra processing required. Not only does it make the developer cheaper, but it also has the disadvantage of taking a long time to clean and dry. Furthermore, there is a disadvantage that the device becomes large-scale. A general fixing machine and a water washing machine have the same structure and use the flora conveyance processing method described above, so they have similar drawbacks in the fixing process and the washing process.

FIG. 8(A) shows an aperture car 1.100 used for brochure film such as drawings, and as shown in the figure,
The film 101 is fixed one by one to a mount +02 made of paper, and in order to process this aperture card 100, the above roller conveyance method cannot be used because the mount 102 cannot be immersed in the processing liquid. Therefore, as shown in Figure (B), one aperture card 100 is sandwiched between the lower body and the north cover, the mount 102 is masked by the F body, and only the film 101 is inserted into the lower body. A spray processing method is used in which developing or fixing is performed by jetting a developing solution or a fixing solution from a provided nozzle 44. In this spray processing method, the developer or fixer is sprayed from the nozzle 44 through the pipe 440 or 441, respectively, so there is an advantage that only one side (the photosensitive side) of the film 101 is developed; When the liquid is injected, air gets mixed into the processing liquid and oxidizes the processing liquid, thereby deteriorating its processing moat power. For this reason, although more processing liquid is used, the processing liquid may not be uniformly sprayed onto the film 101 depending on the shape of the nozzle, resulting in uneven processing. Zaranimata,
This nozzle 44 has a drawback in that the processing liquid tends to crystallize and become clogged.

FIG. 7(A) is a diagram showing a developing machine for roll photographic film using a straight processing method in which this spray processing method is applied to a general roll photographic film 1, and FIG.
), it is held between rollers 33A and 33B provided at the loading port and the discharge port, respectively, and the groove portion formed by the lower body 53 and the upper lid 63 allows the
Photographic film l that is supported and transported by sliding on its four ends
Then, a developing solution is injected from a nozzle 43 provided in the lower main body 53 to perform development. In this straight processing method, since the developer is injected from the nozzle 43, there is an advantage that only one side of the photographic film 1 is developed, but when the developer is injected from the nozzle 43, air enters the developer. It mixes in and oxidizes the developer, which deteriorates its processing power. Therefore, the amount of developer used increases, and depending on the shape of the nozzle 43, the developer is not evenly sprayed onto the photographic film 1, resulting in uneven development. Furthermore, this nozzle 4
Third, there is a drawback that the developing solution tends to crystallize and become clogged.

Furthermore, since the fixing machine and the water washing machine have the same structure and use the above-mentioned straight processing method, there are similar drawbacks in the front processing and the washing processing.

(Object of the invention) This invention was made under the above circumstances,
The purpose of this invention is to enable easy adjustment of finished density, less uneven processing, less scratches on film, faster processing speed, and less maintenance in processing equipment used in photographic film processing steps such as developing, fixing, and water washing. 5. It is almost unnecessary and puts less burden on the operator, and can hold films according to various film sizes (widths). Another object of the present invention is to provide a photographic film processing apparatus that can process only the photosensitive side of the film and consumes less processing liquid when processing general photographic film.

(Jl Summary of the Invention) The present invention relates to a photographic film processing apparatus that performs development, fixing, or water washing processing, and an ultrasonic vibrator that turns processing liquid used in the processing into mist.

A mechanism that changes the width of the processing section according to the width of the film being conveyed, a member that holds both ends of the photographic film according to the width of the film, and a process that corresponds to the film width when processing general photographic film. -2 During the fog,
The apparatus includes a member for sealing both ends of the photographic film so that only the photosensitive side of the photographic film passes through, and performs the processing described in L.

(Embodiments of the Invention) This invention provides a method for processing general photographic film by atomizing the processing liquid used in photographic film processing such as developing, fixing, or water washing, and holding both sides of the photographic film. By sealing the edges and passing only the photosensitive side of the photographic film through the mist, this is a processing device that solves the above-mentioned drawbacks and can perform developing, fixing, or washing processes according to the film size. Therefore, in order to turn the treatment liquid L into a mist, first, as shown in FIGS. 2(A) to (D),
The following methods can be considered.

(A) 1 yen d As shown in (A), the treatment liquid layer 500
1E electrodes 501 and 502 are inserted into the treatment liquid, and by applying electricity to the electrodes 501 and 502, the foot treatment liquid is heated, vaporized, and turned into mist. In this case, although the structure is simple, the treatment liquid is heated to a high temperature, which deteriorates the liquid treatment ability.

(B) As shown in FIG. 5B, the processing liquid in the processing liquid layer 510 is heated from the outside by, for example, a heater 511, and is vaporized and turned into mist. In this case as well, the structure is simple as in (A) above, but since the processing liquid is heated to a high temperature, the processing ability of the liquid is deteriorated.

(C) As shown in (C) of the same figure, the pump 521 is rotated at high speed by the motor 522 built in the processing soap layer 520 to suck up the processing liquid, and the centrifugal force is used to blow the processing liquid against the wall surface. A fine droplet is created and the droplet is pumped by the 27-n 523. In this case, although there are no disadvantages as in (A) and CB) above, a motor and a pump are required, and the shape of the treatment liquid layer becomes complicated.

(D) As shown in (D) of the same figure, a pair of filters 531 made of cloth or the like built into the processing liquid layer 530 are wrapped around each other, one end of which is immersed in the processing liquid, and the filters are gradually rotated. A fan 532 passes air through the filter 531 to vaporize the processing liquid and turn it into mist. In this case, it is difficult to control the occurrence of fog.

Therefore, in this invention, the structure is simple and the amount of mist generated is easy to adjust, for example, a ceramic crystal oscillator,
Applying ultrasonic vibration to the liquid using an aa wave wave element that utilizes piezoelectric phenomena such as lead zirconate titanate (PZT) for plastics, polyvinylidene fluoride (PVIIF) for plastics, or ceramic composite material (PECM). The process liquid is vaporized to generate a mist of the processing liquid.

FIG. 1(A) shows a cross-sectional configuration diagram of the photographic film processing apparatus of the present invention, FIG. 1(B) is a side view of the processing section thereof, and FIG. This is a diagram of the width changing machine 4JR section viewed from the h side. Here, since the second processing device 2 is commonly used for developing processing, fixing processing, and washing processing, an example in which it is used for developing processing of photographic film will be described below.

In the same figure (A), 7A is a sensor that detects that the photographic film 1 has been conveyed to this developing machine 2.

A pair of ports '-': P3A and 3B are provided at the inlet and outlet of the developing processing section 8 to sandwich and transport the photographic film 1.

511 m), the operator operates an external switch to automatically change the width by a predetermined amount. In this width changing operation, the lower bodies 50A, 508.51A, 518.52 and the knees 1eap, 6o8. The width of e+ can be adjusted while maintaining airtightness. Therefore, as shown in the cross-sectional side view of FIG. The formed groove portions slidably hold and seal both ends of the film 1 in the width direction. The development processing section 8 has its inlet and outlet sealed by a pair of rollers 3A and 3B to maintain airtightness. The lower body 5 is provided with a liquid storage section 4 that stores the developer injected from the injection port 4I, and the liquid portion injected into the liquid storage section 4 is detected by a liquid level sensor 7B. The surface is now under control. The liquid storage portion 4 is provided at its bottom with the ultra-a wave oscillator 40 that generates a mist of the developer. A fan 49 provided in the circulation path pumps the generated fog to the developing processing section 8 to develop the photographic film 1, and returns the fog after the development of the film 1 to the liquid storage section through the port 42. I am suctioning it back to 4 and making fIJO. Further, during development, in order to maintain the transport path of the film L in the development processing section 8 and the above-mentioned fog at the optimum development temperature, a plate-shaped heater 9 is provided in contact with the above-mentioned L:46. 9 is detachably arranged so that it can be removed when unnecessary, such as during washing.

As shown in the side view of [Δ(B)], both ends in the width direction can be slid by grooves formed at both ends of the lower body 5 and the upper cover 6, whose widths are adjusted in advance according to the film width. The paper is held and sealed, and is conveyed while being held between rollers 3B provided at the discharge port. On the other hand, I: The above-mentioned a sonic vibrator 40 provided in the liquid distribution storage section 4 allows the optimal developing concentration (
A developer mist of the amount generated is generated, and is force-fed by a fan 49 provided in the circulation path, and reaches the development processing section 8. Here, the transport path of the film l in the developing processing section 8 and the above-mentioned fog are maintained at an optimum developing temperature by a plate-shaped heater 9 provided at the top of the two lids 6, and both ends are sealed. Therefore, only one side (photosensitive side) of the photographic film 1 is developed at the optimum development temperature and optimum development density.

After completing the above-described development process, the developing machine discharges the developer from a drain port (not shown), injects wood into the developer, passes it through the eight sonic vibrators 40, and generates water vapor. If you do this, you can easily clean the inside without disassembling it.
