Description

[Detailed Description of the Invention] The present invention relates to a film processing apparatus for processing photographed film, such as developing it.

As a method for developing film that has already been shot.

Conventionally, the amount of developer required to develop one roll of film (approximately 30 m) was stored in a developing tank, and the film was fed while being immersed in the developer in this tank. However, this method has the disadvantage that the developing solution becomes fatigued as the film passes through the film, resulting in uneven density between the leading and trailing ends of one roll of film.

To overcome this drawback, a method can be considered in which a developer is continuously sprayed onto the film while the film is being fed, and the developer is collected in a container after spraying.

According to this method, fresh developer is always supplied to the film, so that one roll of film can be developed to a constant density.

In the latter developing method, the developer to be sprayed onto the film is supplied from a supply container, and the developer after spraying is discharged into a collection container, but these containers are used to store one roll of film in order to downsize the developing device. It is sized to accommodate the minimum amount of developer required for processing.

Therefore, each time the user finishes developing one roll of film, he or she must replace the supply container or replenish the liquid, remove the collection container, and discard the liquid in the collection container.

Even if you replace the supply container and strain or replenish the liquid, if you forget to discard the liquid in the collection container, there is a problem that the liquid will overflow from the collection container and contaminate the inside of the device and the area around it. .

The present invention solves the above-mentioned problems and provides a film processing apparatus that prevents the liquid from being forgotten to be disposed of in the collection container.

The present invention will be explained below using specific examples shown in the drawings.

Fig. 1 shows a film forming apparatus to which the present invention is applied. 1 is a machine box, 2 is a door for opening and closing the film supply chamber provided in the machine box 1, 3 is a handle of the door 2, and 4 is a door inside the machine box 1. A door for opening and closing the provided container storage chamber, 5 a handle of the door 4, 6 a take-up reel, 1 a film guide roller, 8 a capstan roller, 9 a power switch, 10 a film feeding speed adjustment dial, be.

Inside the machine box 1, there is a film supply chamber 11 as shown in FIG.
．． Developing section 12, fixing section 13. A washing section 14, a drying section 15, and a container storage chamber 16 are provided.

A reel 18 holding photographed film is loaded into the film supply chamber 11.

The film F wound on reel 18 is Gaitoro-ra 19
, the guide plate 20, the guide roller 2L22, the guide roller 1, the capstan roller 8, and the winding wheel 6.

The developing section 12 includes a spray nozzle 12a for spraying a developer onto the film, and a saucer 12b.

The fixing section 13 and the washing section 14 are also configured in the same manner as the developing section,
It has injection nozzles 13a, 14a and a saucer 13bt14b.

A developer supply container 26, a fixer supply container 21, a washing fluid supply container 28, and a recovery container 29 are removably installed in the container storage chamber 16.

Each injection nozzle 12a, 13a, 14a is connected to a corresponding supply vessel 26. by means of a supply pipe 30, 31.32.
27 and 28, respectively, and each saucer 12b, 13b
t14b is connected to the collection container 29 by a discharge pipe 35.36°31.

The developer contained in the supply container 26 is delivered to the injection nozzle 12 via a supply pipe 30 by a liquid supply pump (not shown).
The fixer solution supplied to the supply container 27 is supplied to the injection nozzle 13a via the supply pipe 31 by the liquid supply pump, and the water contained in the supply container 28 is supplied to the injection nozzle 13a by the liquid supply pump. is supplied to the injection nozzle 14a via the supply pipe 32.

The liquid supplied to each injection nozzle is ejected from the nozzle and sprayed onto the film in the latter receiving tray 12b.

13b and 14b, and discharge pipes 35 respectively.
36.37 to the collection container 29.

While being fed from the film supply chamber 11 to the winding wheel 6, the film is transferred to a developing section, a fixing section, and a washing section.Image 1. It is soaked in a pond, washed with water, and dried with hot air in the drying section.

It is assumed that the film is passed through a predetermined film transport path and wound around the take-up reel 6 before starting the development process.

Also, the liquid supply pump is capstan row-y8 (1')
It shall be driven in conjunction with rotation.

In the above example, Ei 1 image fixation is carried out in a two-bath type, but -
Developing and fixing may be performed using a warm method.

The supply containers 26, 27, and 28 have a size that can accommodate at least the amount of processing liquid necessary to process one roll of film, and the collection container 29 has a size that is at least the sum of the volumes of each supply container. .

FIG. 3 shows a state in which each container is installed at a predetermined position in the container storage chamber 16, and the supply containers 26, 27, and 28 are placed in the container storage chamber 16.
The collection container 29 is arranged so that the handle 29a faces the door side of the storage chamber 16, and the supply containers 26, 27, 2B are shaped so that they cannot be taken out unless the collection container 29 is simply removed. It is composed of

Therefore, when replacing the supply container or replenishing the supply container with liquid, it is necessary to remove the collection container 29, and at this time, the inside of the collection container 29 is almost full of waste liquid.

As a result, the user can be aware of this when removing the container and will not forget to dispose of the liquid in the collection container.

Before use, the opening 26a of the developer supply container 26 is sealed with aluminum foil 40, with an amount of solution sufficient to process one roll of film stored therein, as shown in FIG. When the aluminum foil 40 is set in the container receiving part 41 with the opening 26a facing downward as shown in FIG.
The outflow of the liquid is automatically stopped when the level of the liquid reaches the opening of the container and the liquid remains in the container receiving part 41.

The supply containers 2γ and 28 are also constructed in the same manner as the developer supply container 26.

After processing one roll of film, the supply container 26.2
7 and 28 are almost empty, and the collection container 29 is filled with waste liquid.

Next, when processing a new film, open the door 4, take out the collection container 29 by hand, discard the waste liquid in this container, then take out each supply container, and insert a new supply container into the storage chamber 16. The empty collection container 29 is then installed.

As a result of the above, the user does not forget to dispose of the liquid in the collection container, and it is possible to prevent the inside of the device and the vicinity of the device from being contaminated.

The structure for relating the order of taking out the supply container and the collection container is not limited to the above embodiment, but may be mechanically related.
