Description

[Detailed description of the invention] (Industrial application field) The present invention is a processing device for photographic light-sensitive materials, which is particularly capable of processing a large amount of photographic light-sensitive materials such as long photographic film and photographic paper. This invention relates to a photographic material processing apparatus capable of processing a limited amount of disk film.

(Prior art) As is well known, as a photographic material for cameras, etc.
In place of the photographic film that had been commonly used up until now, disc-shaped photographic materials called disc films were developed. Several types of processing devices or processing machines have been proposed, but all of these processing methods and processing systems have significantly improved the photographic film that has been consumed in large quantities. Many of these methods have been devised based on processing methods or processing systems designed to increase efficiency, and are extremely uneconomical when targeted at disk film, for which demand is still small. I felt that it lacked practicality.

Therefore, the present applicant proposed Japanese Patent Application No. 57-101463 (Japanese Unexamined Patent Publication No. 58-219551) with the aim of improving the conventional processing equipment and processing machines and processing disk film, which is in low demand. However, this was still uneconomical as a device for processing smaller quantities of disk film.

(Problems to be solved by the invention) The invention was developed in view of the actual situation as described above, and it is difficult to process large amounts of photographic materials such as long photographic film and photographic paper. It is an object of the present invention to provide a photographic material processing apparatus which can process a smaller amount of disk film economically.

A hot water tank is provided to keep the temperature warm, and the different processing solutions in the overflow processing solution storage tanks are sequentially introduced and discharged into the dark box in a predetermined order, and the disk film is developed and processed. A disk film processing tank for carrying out various treatments such as bleaching, fixing, and stabilization is installed as a disk film processing equipment section, and overflow treatment from each processing liquid tank introduced into the disk film processing tank is carried out. The present invention is characterized in that each process on the disk film is performed using a liquid.

(Function) Since the present invention is configured as described above,
Conventional photosensitive materials such as photographic film and photographic paper have been processed through development, bleaching, fixing, and washing, with appropriate washing processes in between, as seen in conventional photographic material processing equipment of this type. Each processing such as stabilization is performed in a dark box, and each processing liquid overflowing from each processing liquid tank equipped with a separate processing liquid replenishment device is stored above the dark box for the disk film processing equipment section. The overflow treatment liquid is introduced and stored separately in each overflow treatment liquid storage tank provided at . Next, the overflow processing liquid stored in each overflow processing liquid storage tank is introduced into and discharged from the disk film processing tank in a predetermined order, and the disk film is subjected to so-called development processing. It will be done.
