Abstract

PURPOSE:To simplify structure and to obtain a product of small size and low cost, by installing a conveyance member comprising a magnet moving to each liquid vessel for development, fixation, and water washing, and a film holding frame sliding together with the conveyance member by means of magnetic attraction. CONSTITUTION:An exposed film A is held with a film holding frame 17, a conveyance member 11 comprising a magnet is moved together with a traveling belt 10 opposite to the backside of a partition plate 4 by driving a motor 14, and attracts the frame 17 at the position opposite to a detaining member 18. The frame 17 is sttracted to the front side of the partition plate 4 and follows movement of the member 11, while keeping this state, and slides in contact with a sliding plate 5, and the inner upper faces of a developing soln. vessel 6, a fixing soln. vessel 7, and a washing water vessel 8, thus successively passing through each soln., and the frame 17 is allowd to release the film A down to the vessel 8 with a parting member 19 at the position apart from the vessel 8, thus finishing the development processing of the film A.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic developing machine, particularly an automatic developing machine suitable for developing dental X-ray film. Conventionally, this automatic developing machine has two developer tanks and two fixer tank.

A large number of transfer rollers are arranged in motion along a transfer path for transferring the entire film to the washing tank, and the rotational force of the drive motor is transmitted to the large number of transfer rollers via a transmission shaft. As a result, the structure was extremely complex, large, and costly.

Maintenance and inspection are troublesome, and since it is not possible to completely shut off the roller drive section and the liquid tank, the developing and fixing fluid adheres to the drive section and corrodes them, leading to poor durability. ! −
In addition to damage, the rollers disposed in the liquid had short service life.

Therefore, this book 1 has been developed to improve the above-mentioned defects, and the embodiment of the present application will be described in detail below with reference to the drawings. A partition plate (41) airtightly divides the tank chamber (3) into the front and back.

1, While slidingly touching the entire inner surface of the rear wall of +81, infiltrate each liquid in the developer tank (61, the front liquid tank (7) and the washing tank (8)), and then enter the liquid at a distance from the washing tank (8). At 1rt, the film holding piece (171) falls into the washing tank (8) due to the separation member (circle). That is, the development process on the film is completed.

Next, the upper casings (11 to 20+) are removed and pulled out from the washing tank (8), and the film is removed from the liquid tank and dried.

In addition, in the above 2, there is a developer tank (6) in the liquid tank chamber (3),
We have described the case where the fixer tank (7) and the washing tank (8) are stored and the film is dropped into the Ak washing tank (8) after washing. It goes without saying that a storage tank containing all of the film A may be stored in the liquid tank chamber (3) and the film A' may be dropped at the position of this storage tank.

As described above, according to the present application, the first developed film is sequentially transferred into each processing solution by magnetic action, so unlike the conventional method, a large number of transfer rollers are arranged along the film transfer path. Compared to the above, the structure is far more electric, and it is possible to obtain a smaller and cheaper product, and maintenance and inspection are easier.2 Also, since the liquid tank chamber and the drive chamber can be completely isolated, the drive device However, depending on the treatment liquid, there is no risk of damage, and it has a highly durable surface.
