Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic developing device for exposed photosensitive materials, and particularly to an improvement of a gas exhaust device provided in the automatic developing device.

[Conventional technology]

When developing and fixing photographic materials, a large amount of gas is generated. In particular, sulfur dioxide gas and acetic acid gas emitted from the fixing solution can corrode the main body of the device and attached devices, and damage the photosensitive material. It can damage the film and is also considered harmful to the human body.

For this reason, automatic developing equipment that processes photographic photosensitive materials is equipped with an exhaust device that exhausts the generated gas to the outside of the equipment to protect the equipment and the photosensitive materials.
Furthermore, consideration has been given to managing the hygiene of workers by discharging the exhaust gas outdoors.

FIG. 3 shows the specific structure of such an exhaust system, and shows the developing tank 1, fixing tank 2,
The washing tank 3 and the drying section 4 are covered by an upper lid 5 that covers the entire device.
Furthermore, there is an inner lid 6 near the top of each tank.
The gas generated from each tank is discharged from an intake port 6a opened on the inner surface of the inner lid 6 through an intake pipe 7 to the outside of the apparatus or outdoors by a blower 9.

This inner lid 6 collects the generated gas, and
It also has the effect of suppressing the scattering of droplets generated from the rear end when the photosensitive material is turned over, and is particularly effective in preventing corrosion of the upper lid 5. However, it is also useful for cleaning the above-mentioned tanks and the conveyance members housed in them. In this case, it must be removed, and therefore it is detachably attached to the intake pipe 7 fixed to the device.

The state of the connection is as shown in FIG. 4, with the inner lid 6 being held at a portion (not shown) relative to the main body of the device, and the relay member 8 being press-fitted or screwed into the intake pipe 7. Thus, they are connected to form a continuous exhaust passage, but the above-mentioned cleaning is frequently performed on a daily basis, and in such a configuration, the operation of attaching and detaching the relay member 8 must be repeated each time. Also, during cleaning, processing liquid and cleaning water may enter from the opening at the end of the intake pipe 7, contaminating the exhaust system and impairing its function.

[Problem that the invention seeks to solve]

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic developing apparatus having a structure in which an inner cover can be easily attached and detached, and processing liquid or cleaning water does not enter the end of an intake pipe.

[Means for solving problems]

The present invention provides an insertion port for an exposed photosensitive material, an intake port that is opened from the insertion port side into at least a developing tank, a fixing tank, and an inner lid that covers and surrounds the upper part of these tanks. an upper lid; The automatic developing device has an apparatus body configured such that the inner lid is installed separately from the intake pipe, and the intake port of the intake pipe is connected to the upper end of the intake pipe. an inner cylinder part that is provided with a mouth and has a hole in the upper end portion of the intake pipe that overlaps with the intake port of the pipe wall of the intake pipe and that fits on the outside of the intake pipe; and an outer cylinder part that surrounds the outside of the inner cylinder part. The automatic developing device is characterized in that it has a structure in which the inner cylinder part and the outer cylinder part are covered with a cap consisting of a mirror part connecting at one end side, and by this structure, the above object is achieved.

〔Example〕

An embodiment according to the present invention is shown in FIGS. 1 and 2.

This apparatus is arranged with a developing tank 11, a fixing tank 12, a washing tank 13, and a drying section 14, and the photosensitive material F inserted from the insertion stand is transported between rollers constituted by conveying members arranged in each tank. The structure is such that a U-shaped path is obtained through which the processing liquid and washing water are sequentially passed through, and then dried and discharged to the outside of the apparatus.

The developer tank 11, the fixing tank 12 and the washing tank 13
At the top of the device, there is an inner lid 1 separate from the upper lid 15 of the device main body.
6 is provided independently and removably, and the gas, steam, or photosensitive material F generated from each tank is
The rear end part is designed to prevent droplets from reaching the upper lid 15 when it is reversed into a U-shape.

An intake pipe 17 is disposed on the side of the washing tank 13 and within the range covered by the inner lid 16, and a lid member according to the present invention, that is, a ventable cap 18 is attached to the end of the intake pipe 17. ing.

The details will be explained with reference to FIG. 2. The cap 18 is a cap-shaped member in which an outer cylinder 18a and an inner cylinder 18b are connected at the upper surface by a mirror part and are integrated. A plurality of holes are provided on the circumferential surface, and when the cap 18 is attached and fixed to the end of the intake pipe 17, the holes match with holes of the same shape and size provided at the end of the intake pipe 17. to form an air intake port 17a.

Therefore, the intake pipe 17 is provided with the cap 18 at its end, and is capable of sucking in gas or water vapor from the intake port 17a and discharging it outside the apparatus or outdoors using the blower 19.

On the other hand, even if the intake pipe 17 is exposed to processing liquid or cleaning water when the upper lid 15 and the inner lid 16 are removed and the aforementioned processing tanks and transport members are cleaned, the outer cylinder 18a of the cap 18 is Since the opening 17a is covered, there is no possibility that the liquid will enter the intake pipe 17, and therefore, the exhaust device will not be contaminated by liquid and can efficiently exhaust only gas.

Furthermore, in the structure of the exhaust system according to the present invention, as is clear from the drawing, there is no need to connect the inner cover and the intake pipe, so the inner cover is simply placed on the top of each tank described above, and its removal is easy. As a result, cleaning and inspection work can be done much more efficiently.

〔Effect of the invention〕

According to the present invention, it is possible to provide an automatic developing device in which the inner lid covering each processing tank can be easily attached and removed, and there is no danger of processing liquid, cleaning water, etc. entering the intake pipe, and is safe and has excellent exhaust performance. .
