Description

[Detailed explanation of the invention] This invention consists of rotating rollers that are pivoted on the front and rear sides of the left and right inner surfaces of a box-shaped container provided inside the container.
A box-shaped case in which an endless belt is stretched between each belt, a dental film container frame is constructed between numerous sawtooth-like irregularities provided on the surface of the endless belt, and the film container frame is placed in a box-shaped container body. Developing is carried out using the developer, washing water, fixer, etc. in a plurality of compartments provided in the developing tank, which are suspended in the developing tank and transferred through the developing tank as the endless belt rotates. Water washing and fixing can be carried out extremely smoothly and automatically, without staining or damaging the finished film surface. Also, dental film can be removed from raw film before development or from film that has been exposed to X-rays. When removing the device from the external container frame, it is placed in a dark box provided in the lid, and by the operation of the operating mechanism provided in the dark box, it can be done extremely easily and easily even in a bright room. An automatic X-ray dental film developing device that is equipped with a hanging transfer type developing mechanism of a container frame for dental film removal and a lid with a dark box operation mechanism for use in a bright room, which allows the removal of dental film to be carried out without the risk of exposure to light. The purpose is to obtain.

However, in conventional developing devices, when transferring dental film, the film is placed between a number of rollers that are laid horizontally in a row on both sides of a box-shaped container. The rollers are constructed so that they are moved by the rotation of the rollers and exposed to the action of the developer, fixer, washing water, etc. in a plurality of sections of the developing device. However, with this type of film, as the developer, fixer, etc. age, the hardening agent stops working, and the surface of the film becomes slimy, making it impossible to transport the film between the many rollers. However, there is a disadvantage in that the developing process cannot be carried out in a dark room, and there is no mechanism for operating a dark box that can be operated very easily even in a bright room.

In order to solve the numerous problems of conventionally known developing devices, the present invention proposes an automatic X-ray dental film developing device that has an innovative structure and excellent functions and effects based on the structure, as described in the purpose section. He devised a container.

A door section 24 that can be opened when the object is placed on the rack is closed. In that case, the endless belt 16, 16'
A predetermined number of dental film removal frames 18 placed thereon are moved through the developing chamber P while receiving the action of the developer in the developing chamber P of the developing tank 20. After moving and escaping from the ward P, it enters the washing ward P, which follows it, and then enters the rinsing ward P, being washed with the washing water in the washing ward P. After moving in Q and escaping from that section Q, it enters the following fixing section R and is fixed by the action of the fixer in the fixing section R. At this time, the developing process is completed and the door 2 of the lid C is closed.
4 is opened, and the dental film removal container frame 18 is taken out of the X-ray dental film automatic developing device through the entrance/exit portion 25 thereof. Thereafter, when the dental films F and F' are removed from the clip-like fasteners K and K' provided on the container frame 18, a completed developed film is obtained.

Since the present invention is used as described above, the hanging and movable dental film removal device frame can be handled very smoothly without any fear of falling off from the rotating endless belt. There is no need to worry about contamination or damage to the surface of the dental film.Furthermore, the development of the dental film can be done as quickly and easily in a bright room as in a dark room, thanks to the dark box operation mechanism for the bright room. In addition, since the box-shaped container body 3 is removably installed in the container box 1, if the inside of the container box 1 and the box-shaped container body 3 become dirty after use, the box-shaped container body 3 can be removed. If you take out the box-shaped developing tank 20 from the container 1 and separate and wash the container 1, the box-shaped container 3, and the developing tank 20 separately, you can clean it very easily and without any trouble. This has remarkable practical effects.
