Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This invention relates to a photosensitive material processing apparatus, and more particularly to a photosensitive material processing apparatus that transports and processes disk films and roll films in the same processing tank. .

(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.

In addition, installing dedicated photosensitive material processing equipment independently in this way requires a large space, so
As disclosed in Japanese Patent Application Laid-open No. 58-219551,
Some photosensitive material processing apparatuses include a roll film processing mechanism and a disk film processing mechanism.

Generally speaking, as disclosed in Japanese Patent Application Laid-open No. 59-37542, there is a method in which a roll film and a disk film are processed on the same line using a film holder, depending on the processing time of each film.

(Problems to be Solved by the Invention) As described above, when a processing mechanism for roll film and disk film is built into a photosensitive material processing device, the processing paths are separate, which increases the size of the device and makes the mechanism complicated. become. Furthermore, in a film holder that processes roll films and disk films on the same line, the mechanisms for driving the film holder and supporting the film are complicated.

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. We proposed a photosensitive material processing equipment.

By the way, disk film is similar in shape to roll film, and since roll film is stored in a cartridge, setting both in the same photosensitive material supply unit for transport would result in a complicated structure and increase production costs. There are problems such as bulkiness.

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 that has a simple structure and is capable of transporting a disk film and a roll film.

(Means for Solving the Problems) In order to solve the above 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. It is characterized by being equipped with a photosensitive material supply section into which films are inserted independently.
