Is injected into the flow path 61 to reach the inner wall surface 65a of the bellows body 65, thereby enabling washing with water.

FIG. 9 is a flowchart for explaining the operation of the processing liquid supply device configured as described above. In this figure, when the processing liquid in the apparatus 1 is consumed, the user is prompted to replenish the processing liquid, and the user sets the container 29 to the state shown in FIG.

Subsequently, in step S 1, power is supplied to the pump 79 and the solenoid valve 78 in accordance with an instruction from the control unit 30, and water is injected from the hollow pipe 66 to flow through the channels 60 and 6.
Perform "pre-wetting" in 1. This “pre-wetting” prevents the treatment liquid filled in the container 29 from directly touching the inner wall surface, prevents the treatment liquid from remaining, and reliably prevents the growth due to solidification. Preparation for ejection is now complete, and step S2
In step S3, the motor 58 is started, and the cutting edge 62 is moved to the position shown by the two-dot chain line in FIG. 6, and the motor 58 is driven until the discharge position where the sealing member is pierced in step S3. Then, the processing liquid is discharged into the flow path 60. Then, after step S3, in step S4, the motor 58 is further driven continuously, whereby the cam member 72 is driven.

Next, in step S6, the pump 79
And the electromagnetic valve 78 is turned on, water is injected from the hollow pipe 66 to wash the flow path 60 and the flow path 61 inside the bellows body 65, and provided in the replenishment tank 19 in the next step S7. By jetting water until the liquid level sensor 80 is turned on, a diluted processing liquid is obtained. Thereafter, in step S8, the pump 79 and the electromagnetic valve 78 are turned off, and the process ends. Thereafter, the respective processing liquids are supplied to the respective processing liquid layers 16. By injecting water at the predetermined timing as described above, it is possible to completely prevent the processing liquid from remaining in the flow path.

FIG. 10 is a view showing a state in which the mounting member 42 driven between the holding position for holding the container 29 and the standby position is rotated to the inclined position. When the container is tilted to the inclined position after the supply, the container opening 29a is opened.
Is an elliptical bellows body 6 having a long axis in the left-right direction on the paper surface.
5 is separated from the opening. For this reason, it becomes impossible to collect the drips of the processing liquid dropped from the container opening 29a.

Therefore, an extension 65f located below the container opening 29a is extended from a part of the upper opening of the bellows body 65 as shown in the figure, and the processing liquid drops are collected in the direction of the arrow. In this way, it is possible to prevent the inside of the apparatus 1 from being contaminated by the drop of the processing liquid.

The hollow tube 66 is not limited to the above structure as long as it is configured to be able to spray water into the flow channels 60 and 61. May be provided.

As described above, the driving force for perforating the sealing member 55 of the container 29 can be reduced.
After the sealing member 55 is pierced, the outflow resistance of the processing liquid can be reduced to shorten the outflow time, and the processing liquid can flow through the flow paths 60 and 6.
It is possible to provide a processing liquid supply device that does not remain in the first processing liquid.

Since some types of processing liquids are likely to be crystallized and those that are unlikely to be crystallized, crystallization can be prevented by flowing water as described above for those which are likely to crystallize. It is not necessary to provide an injection pipe for a processing solution that is unlikely to be changed. Further, by providing the bellows, contact between air and the processing liquid can be prevented, and crystallization and oxidation can be effectively performed.

<Photosensitive Material Conveying Apparatus> Next, FIG. 11 is a schematic structural view of the conveying rack 17, which is detachably provided as described above with respect to the processing liquid tank 16 storing each processing liquid.
The paper P is used as a transport unit that transports the paper P along a transport path indicated by an arrow D3 in FIG.

In this figure, the transport rack 17 has all the transport rollers 83 and 84 of the transport rack 17 via a power transmission mechanism composed of a worm gear and a worm wheel from a common drive motor 20 shown by a broken line in FIG. The direction change roller 85, which is pivotally supported downward, is driven synchronously, and can be conveyed without generating a speed difference in the nip between the respective conveyance rollers.

The transport rack 17 is removably disposed in a processing liquid tank 16 storing the processing liquid up to a predetermined liquid level L, and a guide (not shown) with the emulsion surface Pa of the paper P facing upward. After being guided downward by the member and conveyed downward and reaching near the bottom surface of each processing liquid tank 16, the nip portion between the direction changing roller 85 and the conveyance roller 84 obtains a conveyance force and moves upward. , And then are conveyed upward and discharged downstream. The direction change roller 85 is rotated near the bottom of each processing tank via a bevel gear and is driven to rotate in the direction of the arrow, thereby turning the photographic paper conveyed downward so as to face upward. In order to perform the rotation, three conveying rollers 84, which are rubber rollers made of ethylene propylene resin, which are driven as described later in contact with the outer peripheral surface of the direction change roller 85, are provided so as to be driven.
The direction is changed while feeding the paper P by the conveyance force generated in the nip between the rollers. Further, between the transport rollers 84, guide members 86, 86 formed with a number of grooves along the transport direction are provided for guiding the back surface Pb side of the emulsion surface Pa of the paper P.

These transport rollers 84 are provided with divided roller portions formed of an elastic body and divided into a plurality of portions as described later, so that the pressure on the direction change roller 85 does not fluctuate, and Care is taken to prevent skew. The paper P conveyed upward by the direction change roller 85 to the downstream side in the direction of arrow D3 is a nip between the conveying rollers of an unillustrated two-groove elastomer roller made of a polyolefin-based elastomer material near the liquid level. Transported further upward by the
It is configured to be conveyed toward a guide member (not shown) at a nip portion between the rubber roller having two grooves and an elastomer roller formed of a polyolefin-based elastomer material having many grooves.

As described above, the transport rollers 83 are arranged in a zigzag manner so as to obtain a transport force by the stiffness of the paper P on the way of the transport path composed of a large number of transport rollers. The transport roller 83 in the processing liquid
Developing, fixing, and stabilizing processes can be performed while smoothly performing a chemical reaction of each processing solution on the emulsion surface Pa without sandwiching the processing solution in a nip portion between them.

FIG. 12 is a sectional view taken along line XX of FIG. In this drawing, the same reference numerals are given to the components already described and the description is omitted, and the pair of rack bases 88 of the transport rack 17 are located inside the front and rear wall surfaces of the processing liquid tank 16 as illustrated. As described above, the transport rollers 83 and 8 are fixed in a space formed between the rack bases 88 by a member (not shown).
4 and the direction changing roller 85 are supported by resin bearings 90 respectively. Hereinafter, the support structure of the transport roller 84 will be described as a representative, but the transport roller 83 is also supported in a similar manner. Since the transport rack 17 requires chemical resistance, resin parts are used for metal parts in principle except for the cores of the transport rollers 83 and 84.

Accordingly, the illustrated conveying roller 84 provided around the direction changing roller 85 is connected to the rack base 8 made of resin.
8 is formed so as to axially support a mandrel 84a of a chemical-resistant stainless steel rod by a resin bearing 90 provided in the hole formed in the hole 8, and is divided into a plurality of mandrel 84a formed of an elastic body. Divided roller portion 84b is integrally formed.

Each transport roller 84 has a direction change roller 85.
A gear 92 that meshes with a gear 91 fixed to is fixed, and each of the transport rollers 84 is driven as the direction change roller 85 is driven by the power transmission mechanism.

Then, each conveying roller 84 is connected to the resin bearing 9.
After supporting at 0, it is possible to play back in the thrust direction,
In addition, a resin retaining ring 93 is provided in the groove of the mandrel 84a to prevent falling off.

FIG. 13 (a) is a cross-sectional view showing a state in which the conveying roller 84 is supported by a resin bearing 90, the resin retaining ring 93 is fitted, and after the completion, it is moved in the direction of the arrow to the right after completion. FIG. 13 (b) is a cross-sectional view showing a state in which it has moved in the direction of the arrow pointing to the left.

In this figure, the same reference numerals are given to the components already described, and the description thereof will be omitted.
In order to allow the 4a to be smoothly rotated after being pivotally supported in the through-hole portion 90a of the resin bearing 90, the contact surface 93a of the resin retaining ring 93 and the contact surface 90c of the resin bearing 90 are required. It is necessary to secure a clearance g in the thrust direction. By securing the clearance g, variations in the dimensional accuracy of each component are absorbed, and dimensional changes due to thermal expansion are dealt with.

As shown in FIG.
Groove 8 for fixing resin retaining ring 93 when is moved.
The corner portion 84k of 4c is a through hole 90a of the resin bearing 90.
Corner portion 84k contacts the opening edge when the through-hole portion 90a of the resin bearing 90 is formed as a simple through-hole. Generally, since the groove 84c is formed by lathing using a parting tool after chucking the mandrel 84a, the corner 84k of the groove 84c is sharp. Therefore, a chamfer 90b for preventing mechanical interference with the corner 84k is formed. By forming the resin bearing 90 in this way, it was confirmed that the wear amount was reduced to half of the conventional case. The shape for preventing mechanical interference with the corner 84k is not limited to the chamfering described above, and the stepped portion 9 shown in FIG.
Needless to say, 0d may be used. The annular groove portion 90f of the resin bearing 90 is formed so as to urge the transport roller 84 toward the direction changing roller 85 by providing an endless coil spring (not shown). For this reason, the resin bearing 90 is provided on the rack base 88 so as to be movable in the radial direction of the direction change roller 85.
