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 that transports and processes a disk film in a processing tank.

(Background of the Invention) For example, as a photographic light-sensitive material, there is a disk-shaped disk film, and because this disk film has a different shape and processing time from a strip-shaped roll film, each needs its own dedicated photosensitive material processing equipment. There is something to process.

Installing dedicated photosensitive material processing devices independently requires a large space, so as disclosed in Japanese Patent Application Laid-Open No. 59-37542, a film holder is used to store roll film and disk film. There is a system that processes both on the same line according to the processing time of each.

By the way, the applicant has discovered that 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. We proposed a small device that processes

(Problem to be Solved by the Invention) In the device in which the disk film is attached to the conveyance leader in this way, the disk film is attached to the conveyance leader outside the apparatus, and is inserted into the photosensitive material supply section through the lid or dark bag into the specified position. The installation work is inconvenient if it is set in this position.

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 easily set on a transport leader.

(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 is transported and processed in a processing tank from a photosensitive material supply section by a transport leader. The present invention is characterized in that the photosensitive material supply section is provided with an attachment mechanism for attaching the disk film to the conveyance leader.
