Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a photosensitive material processing apparatus in which a disk film is processed by sequentially transporting it through transport paths formed in a plurality of processing tanks.

(Background of the Invention) For example, as a photographic material, there is a disc-shaped disc film, and this disc film has a different shape from a strip-shaped roll film, and because of the difference in processing time, a special film holder is required. There are photosensitive material processing equipment that uses a complex mechanism different from roll film to convey and process film.

In addition, as a device that can process both a disk film and a roll film, as disclosed in Japanese Patent Application Laid-Open No. 59-37542, a film holder is used to transport the disk film and the roll film on the same line. There are things that need to be processed.

(Problems to be Solved by the Invention) As described above, in the mechanism for transporting a disk film using a film holder, driving the film holder and supporting the film become complicated, and the apparatus becomes large. For this reason, the applicant has decided to use disc film in the same way as roll film.
We have proposed a photosensitive material processing apparatus that has a 1-ton structure and processes a photosensitive material by sequentially transporting the material through transport paths formed in a plurality of processing tanks.

By the way, the center of the disc film is, for example,
Either the disc film is attached to a transport leader and transported, or the disc film exits the transition part at the decoy part of the transport path from one processing tank to the next processing tank, and the end of the disc film enters the transition part of the next processing tank. There is a risk of interference with the transport mechanism such as the disk film or rollers. For this reason, it may be possible to make the transition portion of the conveyance path larger than necessary, which would lead to problems such as an increase in the size of the apparatus.

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 can smoothly convey a disk film and further downsize the apparatus.

(Means for Solving the Problems) In order to solve the problems described above, the present invention provides a photosensitive material processing apparatus that sequentially transports and processes disk films through transport paths formed in a plurality of processing tanks. +iii The transition part of the conveyance path formed between the processing tank and the next processing tank,
It is characterized by being formed to allow transportation of the disc film.

(Function) In this invention, the disk film is processed by sequentially transporting it through transport paths formed in a plurality of processing tanks. Then, the end of the disc film exiting the transition part of the transport path formed between the processing tank and the next processing tank and the end of the disc film entering the next transition part may come into contact with each other, or the transport mechanism may It is transported smoothly without contact with rollers, etc. Furthermore, this transition section is formed to allow transport of the disk film, thereby shortening the interval between the processing tanks and downsizing the apparatus.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a main body of a photosensitive material processing apparatus that blocks external light. On one side of the main body 1, a photosensitive material supply section 4 having a roll film supply section 2EL and a disk film supply section 3 is provided. and a photosensitive material take-out section 5 on the other side.
is provided. Between the photosensitive material supply section 4 and the photosensitive material take-out section 5, that is, inside the main body 1 of the apparatus, a developing device M6, a bleaching tank 7, a fixing tank, and a fixing tank are successively arranged. fI8, water wash or stable N! 9 and a drying section 10 are provided, and a predetermined amount of processing liquid is stored in each of these processing tanks.

Incidentally, the processing Fl tank may be composed of a developing tank, a bleach-fixing tank, a washing tank, or a stabilizing tank.

A waste liquid tank 11.12 is placed at the bottom of the treatment tank.
It is designed to store overflow waste.

Further, the waste liquid may not be stored in the apparatus main body 1 as described above, but may be discharged to the outside.

A conveyance path 14 is formed by a conveyance mechanism 13 from this photosensitive material supply section 4 to a developing tank 6, a bleaching tank 7, a fixing tank 8, a washing or stabilizing tank 9, a drying section 10, and a photosensitive material take-out section 5.
The photosensitive material is conveyed along this conveyance path 14 by a conveyance leak 15 .

The conveyance leak 15 is connected to the leak main body 1 as shown in FIG.
An engagement hole 15b is formed in the center of 5a to engage a conveyance leter blocket (not shown). Leak body 15
On the rear side in the conveying direction of a, a TiSF attachment hole 15c is formed between the engagement holes 15b, and a disk film 17 is attached using an attachment member 16. Further, a circular guide hole 15d is formed around the disk mounting portion to prevent the processing liquid from passing therethrough.

When attaching the roll film 18 to this conveyance leader 15, remove the attachment member 16 and place the
For example, it can be attached with tape (not shown) or the like.

A lower roller 19 is arranged at the bottom of the processing tank, and a pair of lower rollers 20 are arranged at the upper part of the processing tank. A transition portion 14a is formed.

As shown in FIG. 2, this transition portion 14a is located at the center of the transition portion 01, assuming that the diameter of the transition portion is r and the diameter of the disk film is
Immediate question from 1 to the edge of the disc film] 2 is also, If the diameter of the 1 part roller is R, the diameter r of the transition part 4 is R+r>ffi... (2) From this formula (2>).

r〉(D2/8R)=(R/2)・・・・(3)
Must.

Further, the distance l1ilH between the line connecting the centers 02.03 of the pair of upper rollers 20 and the center o1 of the crossing portion is H> (ff
i+R) 2- (r+R) 2 (4) Therefore, by substituting the above equation (1) into equation (4), H>...(5) must be obtained.

As a result, the diameter of the transition portion of the conveyance path 14 satisfies the above formula (3), and the distance +!llH between the line connecting the E section roller centers 02 and 03 and the transition portion center 01 satisfies the formula (5). Therefore, the transition portion 14a is formed small.

For example, if R+r<1 and formula (3) is not satisfied,
Disc film 17 exiting the transition section 14a of the processing tank
There is a possibility that the end portion of the disk film 17 entering the transition portion 14a of the next processing tank may interfere with the end portion of the disk film 17.

Also, for example.

H< (u+R) 2- (r+R) 2 If the equation (4) is not added to 114, the end of the disk film 17 may come into contact with the -F section roller 20.

Next, the operation of this embodiment will be explained.

When processing the disc film 17, prepare the mounting member 16, insert it into the disc mounting hole 15c of the transport leader 15, attach the disc film 17 to the transport leader 15,
Set the disc in the film supply section 3. Then, the engagement hole 15c engages with a conveyance block (not shown) of the processing tank by the conveyance mechanism 13, and the conveyance leader 15 is conveyed along the 'conveyance path', returned by the lower roller 19, and returned to the conveyance path 1.
It passes through the transition section 14a of No. 4 and is transported to the next processing tank.

Similarly, the conveyance leader 15 also carries out the following steps in the processing tank of the next process.
The disc film 15 is transported to the next processing tank via the transition section 14a, and is thus transported and processed.

At this time, the disc film 17 exiting the transition section 14a of the transport path 14 is prevented from interfering with the end of the disc film 17 entering the transition section 14a of the next processing tank.

Further, the end portion of the disc film 17 is transported without interfering with the upper roller 20, and damage to the disc film 17 and transport failure are reduced.

Although this embodiment has been described with reference to a case where it is applied to a photosensitive material processing apparatus that can also process roll films, it is similarly applicable to a photosensitive material processing apparatus that is exclusively used for disc films.

(Effects of the Invention) As described above, in the present invention, the transition portion of the transport path formed between one processing tank and the next processing tank is formed to allow transport of the disk film. When the disc film is attached to the transport leader and transported, there is a risk that the edges of the disc film may interfere with the transport mechanism such as the upper rollers at the transition point of the transport path from one processing tank to the next processing tank. It can be transported smoothly without any problems.

In addition, the number of openings can be set to a minimum, making it possible to downsize the device.
