Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a photosensitive material processing apparatus, and more particularly to a photosensitive material processing apparatus that transports and processes a disk film in a processing tank.

(Background of the Invention) Photosensitive materials include, for example, disk-shaped photographic materials and roll films in the form of strips, and each of these photosensitive materials is processed by a dedicated photosensitive material processing device. .

For this reason, various proposals have been made to process these two types of films with a single photosensitive material processing apparatus (for example, see Japanese Patent Laid-Open No. 59-37542).

However, in the conventional technology, because the development processing time of the disc film is different, or because the support mechanism inserts a large number of disc films into the transport holder, a method is adopted in which the transport holder is lifted from the processing tank and transported. are doing.

(Problems to be Solved by the Invention) With such a structure, it is possible to efficiently process a large amount of disc film, but the operation and structure for automatically developing the disc film are complicated, and the equipment had no choice but to become large.
