Abstract

PURPOSE:To simplify attaching and detaching of an inner lid and to prevent processing liquid etc. from entering end part of a suction pipe by providing a cover member at the end part of the suction pipe that discharges generated gas. CONSTITUTION:Gas generated from a developing tank 11, a fixing tank 12, a washing tank 13 etc. is discharged through a suction pipe 17. A cap 18 made up of an inner pipe 18b, an outer pipe 18a and provided with an inlet port 17a that forms a cover member. As the pipe 17 is not connected directly to the bottom face of the inner lid 16 in this constitution, attaching and detaching of the inner lid 16 is made simple, and at the same time, getting-in of processing liquid and washing water to the end of the pipe 17 can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a gas exhaust device provided in an 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 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.This protects the equipment and the photosensitive materials, and furthermore, by discharging the exhaust outdoors, it is safe for workers. Consideration has been given to hygiene management.

Figure 3 shows the specific structure of such an exhaust system, in which the developing tank 1, fixing tank 2, washing tank 3, and drying section 4 inside the device are shielded by an upper lid 5 that covers the entire device. Further, an inner lid 6 is provided near the top of each of the various types, and the gas generated from each type 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 proar 9. It is designed to be ejected.

This inner lid 6 has the effect of concentrating the generated gas and 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 6. In order to wash the transport members and the transport members housed therein, they must be removed, and for this purpose, they are detachably attached to the intake pipe 7IC fixed to the device.

The state of the connection is as shown in FIG. 4, and the inner cover 6 is held at a part (not shown) with respect to the main body of the device, and the relay member 8 is press-fitted or screwed into the intake pipe 7. Although they are connected to form a continuous exhaust passage, the above-mentioned cleaning is often performed on a daily basis, and in such a configuration, the relay member 8 is
The operation of attaching and detaching the exhaust system must be repeated, and during cleaning, processing liquid and cleaning water may enter through the opening at the end of the intake pipe 7, contaminating the exhaust system and possibly 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 in which the inner cover can be easily attached and detached, and the processing liquid or cleaning water does not enter the end of the intake pipe.

[Means for solving problems]

The present invention prevents processing liquid and cleaning water from entering by locating the end of the intake pipe within the inner lid and attaching a lid member to the end, while gas and water vapor are provided at the base of the lid member. The device is configured to take in gas from an intake port and exhaust it to the outside of the device, and is equipped with an exhaust device that is provided with an intake pipe and discharges gas generated from the processing liquid in the processing tank to the outside of the device, and the end of the intake pipe This is achieved by an automatic developing device characterized in that it is provided with a lid member that allows air to be taken in.

〔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 table is transported by roller pairs constituted by conveying members arranged in various ways. The structure is such that the liquid is processed through a U-shaped path, sequentially passes through processing liquid and washing water, and then is dried and discharged from the apparatus.

At the top of the developing tank 11, fixing tank 12, and washing tank 13, an inner lid 16 is provided which is detachable and separate from the upper lid 15 of the main body of the apparatus. When the material F is reversed into a U-shape, the rear end part is designed to prevent droplets from reaching the upper lid 15.

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 at its end there is a lid member according to the present invention, that is, a ventable cap 18.
is installed.

To explain the details with reference to FIG. 2, the cap 1
Reference numeral 8 denotes a cap-shaped member in which the outer cylinder isa and the inner cylinder 18b are connected at the upper surface and are integrated, and a plurality of holes are provided on the circumferential surface of the inner cylinder 18b. Intake pipe 17
When it is attached and fixed to the end of the intake pipe 17, it matches a hole of the same shape and size provided at the end of the intake pipe 17 to form an intake port 17&.

Therefore, the intake pipe 17 is equipped with the cap 18 at its end, and is capable of sucking in gas or water vapor from the intake port 17m and discharging it to the outside of the apparatus or outdoors by the proar 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 washed, the outer cylinder 18m of the cap 18 will not be able to absorb the air. Since the opening 17& 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 eliminate only gas.

Furthermore, in the structure of the exhaust system according to the present invention, as is clear from the drawings, there is no need to connect the inner cover and the intake pipe, so the inner cover is simply placed on the above-mentioned various upper parts, and its removal is easy. Cleaning and inspection work can be done extremely 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. .
