Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an automatic processor for developing a photographed film.

[Prior Art] Photographic film is developed by a pair of rollers.
It is carried out by transferring the photographic film in the processing liquid. Various automatic developing machines for carrying out such a developing process have been proposed, but the one described in Japanese Utility Model Publication No. 60-20115 is superior in that the photographic film can be developed as a flat plate. This will be described below with reference to FIG.

FIG. 4 is a side sectional view of a conventional automatic processor. In the figure,
Reference numerals 1 and 2 denote a pair of film feed rollers, and a indicates a contact portion between them. Reference numerals 3 and 4 are another pair of film feed rollers. The contact portions a to a are almost horizontal. 5 is a pan, 5a is a pan bottom, 6 is its left and right side plates, and 7 and 8 are blades for preventing liquid leakage. Reference numeral 9 is an overflow port provided on the side plate 6, and 10 is a pipe for returning the overflowed liquid to the tank. 11
Is a supply pipe for supplying the processing liquid for the tank. Reference numeral 12 indicates a space for containing the processing liquid.

When the processing liquid is continuously supplied into the space 12, the processing liquid is a to
It is held at the level of line a. In this state, when the film is inserted between the rotating film feed rollers 1 and 2, the film passes through the processing liquid and is fed out of the space 12 by the film feed rollers 3 and 4. This causes the film to process.

When processing photographic film, it is usually necessary to develop, fix,
A washing process is required. In order to carry out these processes, an automatic developing machine having a configuration in which three of the above-mentioned automatic developing machines are continuously arranged is used.

[Problems to be Solved by the Invention] By the way, in the above-described conventional automatic developing machine, since the processing liquid comes into contact with air, the processing liquid may deteriorate relatively quickly. In addition, since the processing liquid of an automatic processor is usually heated to a specified temperature, the water vapor evaporates from the processing liquid, and this water vapor adheres to other parts of the automatic developing machine, and this is removed after the development processing is completed. It had to be wiped off, which required time and effort.

The object of the present invention is to solve the above-mentioned problems of the prior art, to suppress the deterioration of the processing liquid, to prevent the water vapor from adhering to other parts from the processing liquid, and also to perform cleaning. An object is to provide an automatic processor that can be easily performed.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention arranges a first roller pair composed of two upper and lower rollers and a second roller pair composed of two upper and lower rollers so as to face each other. An automatic developing machine for transferring a film between a first roller pair and a second roller pair to perform a developing process includes a lower main body and an upper main body detachably attached to the lower main body. A lid, two side walls projecting downward from the lid, and the first rotatably mounted between the side walls.
Roller pair and the second roller pair, and a first blade elastically contacting the upper roller of the first roller pair and the upper roller of the second roller pair over substantially the entire length of each roller. A lower base of the first roller pair and a lower base of the second roller pair when the lower body is fixed to the base and the upper body is fixed to the bottom of the base. And a second blade elastically contacting each of the rollers over substantially the entire length thereof, and when the upper body is mounted on the lower body, the first roller pair, the second roller pair, and the second roller pair. A supply means for supplying the processing liquid to a space surrounded by the first blade, the second blade and the side walls, and a level defining means for defining the level of the processing liquid in the space. .

[Operation] By mounting the upper body on the lower body, a space is formed by the first roller pair, the second roller pair, the first blade, the second blade, and each side wall. The processing liquid for the film is supplied into the space by the supply means, and the processing liquid in the space is discharged by the level defining means. As a result, the processing liquid level is maintained at a predetermined level higher than the film transfer path. Since the space is almost hermetically sealed by each roller pair and the plate body, the treatment liquid is less likely to come into contact with air, and the steam from the treatment liquid is not discharged to the outside. By removing the upper body from the lower body, the lower body can be easily cleaned.

The blade 61 comes into contact with the lower rollers 25 and 27 of each pair of rollers with the upper main body 55 mounted on the base 56. A hollow tubular body 32, which will be described later, is inserted into the blade fixing portion 60 and the blade 61. In this case, when the outer diameter of the hollow tubular body 32 is equal to or larger than the width of the blade fixing portion 60, the hollow tubular body insertion portion of the blade fixing portion 60 may be formed in the wide width portion 60a as illustrated. Reference numeral 63 is a gear chamber formed by the base 56 and the fitting side wall 57. 64 is the bottom surface of the base 56, side walls 57 and 58 for fitting, and partition walls
It is a groove formed by 65. The partition wall 65 is a wall that partitions the developing unit, the fixing unit, the water washing unit, etc. to prevent mixing of the liquid,
The upper body 55 faces the partition wall 54, and its upper end extends to the vicinity of the film transfer path. The groove of the developing section is shown in FIG.
Only 64 and the groove portion of the fixing portion continuous to the reference numeral 64 are shown. This constitutes the lower main body 66 of the automatic processor.

In the automatic processor of this embodiment, the upper main body 55 is simply replaced by the lower main body.
It is assembled by fitting it in 66. That is, the side walls 51, 52 of the upper main body 55 to the side walls 57, 58 for fitting of the lower main body 66,
The one convex portion and the concave portion are fitted into the other concave portion and the convex portion, respectively. At this time, the roller shaft is inserted into the roller shaft insertion hole 59, and the gears 24G to 25G are housed in the gear chamber 63. The lower rollers 25 and 27 are in close contact with the blade 61.

A gear train installed in the gear chamber, a tank for storing the processing liquid, a pump for discharging the processing liquid from the tank, and a pipe (through hole) for sending the processing liquid sent from the pump to the space between the upper and lower blades 53 and 61. The receiving tray for receiving the processing liquid discharged from the space and returning it to the tank is not shown in the drawing.

FIG. 3 is a partial cross-sectional view of the vicinity of each roller when the upper body is fitted in the lower body. In this figure, the same parts as those shown in FIGS. 1 and 2 are designated by the same reference numerals. Reference numeral 30 denotes a space surrounded by the rollers 24-27, the blades 53 and 61, and the side walls 51 and 52. The side wall 51 is on the front side of the figure and is not shown. The hollow tube 32 is composed of the bottom of the base 56 and a blade.
It is inserted into the space 30 while penetrating 61 and having its upper end 32a positioned at a predetermined height (level). The lower end 32b of the hollow tube 32 is located in a pan (not shown) formed under the base 56. This tray is connected to a tank (not shown).

With the upper body and the lower body fitted in the lower body, each gear is connected to a rotation transmission mechanism (not shown) that transmits the rotation of the motor, and when a pump (not shown) is driven, the processing liquid in the tank Is supplied into the space 30 through the pipe. The supply of the treatment liquid is continued, and when the treatment liquid reaches the upper end 32a of the hollow pipe pair 32, the treatment liquid is returned from the tray to the tank through the hollow pipe body 32. Therefore, the level of the processing liquid does not exceed the upper end 32a. When the film to be processed is inserted between the rollers 24 and 25 by the rotation transmitting mechanism and each of the rollers 24 to 27 is rotated, the film passes through the processing liquid in the space 30 and the rollers 26 and 27 are sandwiched to the outside. Be transferred. If such a mechanism is continuously arranged for each of the developing solution, the fixing solution, and the washing solution, each processing of developing, fixing, and washing is automatically performed by sequentially transferring the film. .

As described above, in this embodiment, since the upper and lower blades are elastically contacted with each roller, the space 30 is in a nearly sealed state, and deterioration of the processing liquid can be suppressed. Further, since the treatment liquid is heated so as to be maintained at a predetermined temperature, water vapor is generated from the treatment liquid, and this water vapor adheres to the mechanical portion inside the developing machine, which may cause deterioration or failure of members. In this embodiment, since the space 30 is almost in a sealed state, water vapor does not leak to the outside and the above inconvenience is solved.

Further, when the upper main body 55 is removed from the lower main body 66, the entire bottom surface of the blade 61 appears, so that the dirt on the blade 61 can be easily removed. Further, when cleaning the groove 64, it becomes possible by further removing the blade 61 from the blade fixing portion 60. Further, since the rollers are attached to the lid 50, there is no possibility of twisting each roller when the rollers are attached. Further, since the partition walls 54 and 65 prevent the outside light from entering, it is possible to prevent the exposure of the film.

In the above embodiments, the position of the supply opening for supplying the treatment liquid to the space and the position of the hollow tube can be arbitrarily selected in consideration of various conditions. In addition, one or a plurality of through holes may be provided on the wall surface of the hollow tubular body near the blade to discharge the processing liquid, thereby eliminating foreign matters accumulated at the bottom of the space. Further, instead of the hollow tube, the groove 64
A passage communicating with the processing liquid tray portion may be provided at a predetermined position.

[Effects of the Invention] As described above, in the present invention, a closed space is formed by contacting the plate bodies above and below two roller pairs.
Since the treatment liquid is circulated in this space, contact of the treatment liquid with air can be suppressed, and its deterioration can be prevented. Moreover, since the vapor evaporated from the processing liquid can be confined in the space, the vapor does not adhere to each component. Also, the lower blade can be easily cleaned.
