Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a photosensitive material processing apparatus, and more particularly to a photosensitive material processing apparatus in which a disk film and a roll film are transported and processed in the same processing tank.

(Background of the Invention) For example, as photographic light-sensitive materials, there are disc-shaped disk films and strip-shaped roll films. Some are processed using photosensitive material processing equipment.

By the way, installing dedicated photosensitive material processing equipment independently requires a large space, so as disclosed in Japanese Patent Application Laid-Open No. 58-219551, a disk film is installed in the photosensitive material processing equipment. Some devices have a built-in processing mechanism and a roll film processing mechanism.

Furthermore, as disclosed in Japanese Patent Application Laid-Open No. 59-37542, there is a film holder in which a roll film and a disk film are processed on the same line according to their processing times.

(Problems to be Solved by the Invention) As described above, in a photosensitive material processing apparatus in which a processing mechanism for roll film and disk film is built-in, the processing paths are separate, resulting in an increase in the size of the apparatus.
Moreover, the mechanism is also complicated. Further, in a film holder that processes roll film and disk film on the same line, the drive mechanism of the film holder and the mechanism for supporting the film are complicated.

By the way, in recent years, with the development of photosensitive materials, it has become possible to process disk films and roll films in the same processing time, so the applicant has decided to pass the disk film through the processing solution in the same way as the roll film. We proposed a photosensitive material processing device that processes photosensitive materials.

In this photosensitive material processing apparatus, the processing liquid is squeezed by a squeeze roller placed on the conveyance path with a predetermined pressing force to prevent the processing liquid from adhering to the photosensitive material and being carried into the processing tank for the next process. . By the way, when transporting disc film, it is difficult to transport disc film because it has a relatively thick core and has a relatively thick core. There is a risk of injury.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a photosensitive material processing apparatus in which a disk film can be smoothly conveyed through a processing liquid tank.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a photosensitive material processing apparatus in which a disk film and a roll film are conveyed and processed in the same processing tank. The present invention is characterized in that it includes a release means for releasing the pressing force of the arranged squeeze rollers when the disk film is transported.

(Function) In this invention, when processing a disk film, the release means is activated to release the pressing force of the squeeze roller. Therefore, when the disc film passes, the pressing force of the squeeze roller is not applied to the disc film, and the disc film can pass smoothly.

(Example) Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.
