Description

Automatic developing machine

The invention relates to an automatic developing apparatus, in particular on a development apparatus, who uses chains to transport the poto paper or film strips.

In a known automatic developing device, a set of handling containers are arranged next to one another, each container having a solution for developing, suspending, fixing, rinsing, bleaching and contains stabilization.

above and at the bottom of each container are known by Drive means driven chain shafts built in. Sprockets are attached to the end of each chain shaft, with An endless chain engages in the lower and upper sprocket on both sides, which at certain intervals is provided with projections.

A rod is hung between two horizontally corresponding protrusions to hold the photo paper or to carry the film strips.

When the chain is moved, the photo paper or slides the film strip successively through the containers, in which it is dealt with.

In this process, a single endless chain is running through all containers, so that the treatment solution adhering to a container when the chain emerges from it remains, is mixed with the solution in the next container, whereby the development process and affects the sharpness of the photo, especially with color films will. In addition, the named endless chain in this type of apparatus "glides through all the containers." friction with the sprockets or the like. exposed under the action of their own weight, so they often tears * Furthermore, the endless chains are attached directly to the frame of the apparatus, which means that they can be washed out properly obstruct the container.

The invention is based on the object of a device to provide the errors listed above eliminated.

In view of this task, a new and usable developing apparatus was arranged, in which each treatment container is equipped with a pair of chain shafts arranged parallel to one another, namely one shaft above and the other assigned to the bottom of the container, with a chain wheel being fixed to each chain shaft at both ends an endless chain provided with projections located at certain intervals is provided on both sides, rods for the transport of the photo paper or film strip being suspended between the respective horizontally corresponding projections.
