(Background of the Invention) For example, as photographic light-sensitive materials, there are disc-shaped disc films and strip-shaped roll films.These light-sensitive materials have different shapes and processing times, so each has its own dedicated Some are processed using photosensitive material processing equipment.

By the way, installing dedicated photosensitive material processing devices 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 device. Some devices have built-in processing mechanisms and roll film processing mechanisms.

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 the processing time of each film.

(Problems to be Solved by the Invention) As described above, in a photosensitive material processing device in which a processing mechanism for roll film and disk film is built in, the processing path is separate, so the device becomes large and the mechanism is complicated. be. Further, in a film holder that processes roll films and disk films on the same line, the film holder drive mechanism and film support mechanism are complicated.

By the way, in recent years, with the development of photosensitive materials, it has become possible to process disc films and roll films in the same processing time, so the applicant has decided to pass the disc film through the processing solution in the same way as the roll film. We have proposed a compact 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 different shape from roll film, so it is difficult to transport disc film through a squeeze roller like roll film. 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.
