Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic light-sensitive material processing apparatus.

[0002]

2. Description of the Related Art In a method in which a processing solution is placed in a processing tank and the exposed photosensitive material is immersed in the processing solution or the stored processing solution is supplied to the surface of the photosensitive material for processing, the processing capacity of the processing solution is Degradation progresses depending on factors such as the throughput factor and the aging factor.

In order to supplement such deterioration and to carry out a stable treatment, a treatment agent has been conventionally replenished. However, there have been various drawbacks since the conventional method is a mixer system in which a liquid processing agent is replenished or a processing solution is prepared by mixing and dissolving processing agent parts to supply a processing solution to a processing tank.

For example, when a liquid processing agent is used for replenishment, there is replenishment in a completely used liquid state. In this case, since the replenishment amount per unit replenishment cycle is large, the replenishment processing agent storage space is large. Since it is large or the storage container uses a resin container to ensure safety, disposal of the empty container becomes a problem, and the storability in the processing liquid state improves, and it deteriorates during storage. There was a defect such as progress.

On the other hand, in the mixer system in which the processing agent parts are mixed and dissolved into a processing solution, each processing agent part has the advantages of maintaining the storability and a relatively small storage space. It is troublesome to handle and requires a mixer for mixing and dissolving, and the drawbacks such as the cost of the mixer and the large space occupied in the apparatus are large.

[0006]

In view of the above-mentioned drawbacks of the prior art, the present invention employs a processing agent form in which the processing agent storage space is extremely reduced and the storage stability is remarkably improved.
It is an object of the present invention to provide a photosensitive material processing apparatus having a good serviceability by simply applying a highly reliable processing agent replenishing means.

[0007]

A light-sensitive material processing apparatus of the present invention which achieves the above object is an apparatus for automatically developing a silver halide light-sensitive material, which comprises at least one processing tank and a light-sensitive material conveying means. Means, a processing agent replenishing means for maintaining the performance of the processing liquid contained in the processing tank, and a control means. The processing liquid is put into the processing tank, and the exposed photosensitive material is immersed in the processing liquid. Alternatively, the processing agent replenishing means for forming the processing solution in the system of supplying the processing solution to the surface of the light-sensitive material and processing the solid processing agent deforms a sheet-like material or a part of the sheet-like material having no air permeability. Receiving a treatment agent individual wrapping in the form of an airtight small chamber formed by bonding two non-breathable packaging materials having a bulge facing each other, and peeling the small chamber by peeling the bonding portion. It was opened and the treatment agent was dropped. Is characterized in that comprises means peel can, and control means for controlling the timing of the cited-out peel and drop.

[0008]

In the present invention, the solid treatment agent means a tablet in which a unit amount is molded into a fixed shape, or a granule or a powder which is not particularly fixed in shape, and the treatment agent sealed in individual treatment agent packages is It is a fixed quantity for one drop. A non-breathable packaging material having a bulge obtained by deforming a part of a sheet-like material means that a container-like bulge is formed in a part of the sheet-like material by a specific molding means, and the remaining flat surface is formed into another sheet-like material. It is used as a bonding part with. Then, the peeling in the present invention is an act of separating and opening the above-mentioned bonding portion, and it is preferable that the ends of the bonding are not fixed to each other for the convenience of starting the peeling.

The form in which a plurality of treatment agent wraps in the present invention are connected is a form in which the treatment agent wraps are connected in one row.
Two strip-shaped packaging materials are bonded to each other to form individual treatment agent individual packages. By appropriately selecting the bonding strength of the bonded portion of the strip-shaped packaging material for the two members, the peeling can be continuously performed and the two members can be sealed tightly to prevent moisture and moisture. Prevents oxygen from entering.

In the present invention, the reason why the processing agent is taken out by peeling off the two members of the packaging material is to easily and surely take out and drop the processing agent, and the form of the processing material itself. In the case of a tablet, an excessive force is not applied to the tablet, the tablet is not chipped, and thus the treatment agent is prevented from scattering. Further, even when the form of the treatment agent is granules or powder, it has the effect of preventing the treatment agent from scattering and preventing the treatment agent from remaining in the packaging material.

Next, in the present invention, the two members of the packaging material are peeled off and wound up in order to prevent the packaging material from scattering after the processing agent is taken out, to make it compact for disposal and to facilitate handling. This is because it greatly contributes to

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in the accompanying drawings.

FIG. 1 is a block diagram for explaining the outline of the construction of a photosensitive material processing apparatus according to the present invention, and FIG. 2 is a schematic diagram showing the concrete construction of the photosensitive material processing apparatus.

The processing bath 1 contains a processing liquid and directly processes the photosensitive material F with the processing liquid. The processing liquid is not necessarily of the type in which the photosensitive material F is immersed in the processing liquid in the processing bath. Good. That is, the term "processing tank" also includes a storage tank that supplies the processing liquid to the processing section related to the processing of the photosensitive material.

Therefore, the destination of the treatment agent dropped by the treatment agent replenishing means 2 is the treatment tank 1 or a part thereof, or
This is performed for the processing liquid reservoir that communicates with the processing unit 100 and supplies the processing liquid.

The control means 3 comprehensively controls the entire apparatus. In particular, it controls the timing of the conveyance of the photosensitive material F and the replenishment of the processing agent. As shown in FIG. The replenishment timing is determined and controlled by performing arithmetic processing according to the signal from the amount detecting means 4.

As shown in the configuration diagram of the replenishing means and the processing section in FIG. 3, the replenishing means 2 is located above the processing tank 1 and comprises a receiving / holding section 6 and a take-up / falling section 7, and the processing agent that has fallen further falls. Associated with and inside the process tank is a holding and filtering means 8 which surrounds and holds until dissolved. The receiving and holding unit 6 receives the treatment agent package 50 (see FIG. 4) in which the treatment agent individual packages are continuous or the treatment agent container 5 that accommodates the treatment agent package 50, and is a portion of the packaging material bonding portion ( The boundary portion 101 is a portion that is temporarily stored and held so that the processing agent can be peeled off and dropped. The winding / falling unit 7 is a mechanism in which the processing agent is dropped from between the two packaging materials that have been peeled off and the tip of the packaging material is gripped and rolled up.

Next, the treatment agent dropped as described above enters the treatment tank 1, but enters the portion surrounded by the holding / filtering means 8, so that the treatment agent in a non-dissolved state does not move to another. Therefore, since the solid processing agent does not inadvertently adhere to the photosensitive material F being processed, processing unevenness does not occur.

Here, the holding / filtering means 8 is a mesh.
Alternatively, since the treatment liquid is allowed to pass through in a porous sheet body, before the treatment agent T is introduced, it is of the same quality as the treatment liquid in the treatment tank 1 and has the same treatment capacity. . Therefore, when the treatment progresses and the treatment capacity of the treatment liquid in the treatment tank 1 is lowered, the treatment liquid having the lowered treatment capacity is also present in the holding and filtering means 8.

Then, by adding the treating agent T, the treating agent T
Is dissolved, the processing capacity is supplemented, and by dispersion, it spreads to the entire processing liquid in the processing tank 1 through the holding / filtering means 8 to supplement the processing capacity.

In order to promote the above-mentioned dissolution, it is preferable to operate a stirring means, and in order to promote the spread to the whole processing solution, it is preferable to operate a means for circulating the processing solution. However, known means can be applied to the stirring means and the circulation means and are not specified in the present invention.

FIG. 4 (A) is a perspective view of the treatment agent package 50, and FIG. 4 (B) is a partial cross-sectional view when the treatment agent drops.

These figures show a situation in which the processing agent container 5 is peeled off and the processing agent T is dropped.
10 is a non-breathable packaging material having a bulge portion 501 obtained by partially deforming a sheet-like material, and the treatment agent T is a treatment agent package.
Since the bulge portion 501 is stored in the bulge portion 501, the peeling is performed as a positional relationship in which the bulge portion 501 is on the upper side in order to drop it by its own weight. Therefore, the flat sheet-shaped packaging material 11 is
Peeling is preferably performed in a positional relationship of being downward or obliquely downward. However, when it is to be peeled substantially horizontally to the left and right for the convenience of the configuration, the bulge portion 501 has the slope 5 on the side cylinder portion.
With 02, it is possible to encourage the processing agent to drop by its own weight.

Next, FIG. 5 shows a uniaxial winding type replenishing device. FIG. 5 (A) is a perspective view of the winding and dropping section, and FIG.
(B) is a plan view of the winding shaft.

A semi-cylindrical member fixed by peeling from the tip of the treatment agent package 50, separating the packaging materials 10 and 11 so as to surround the semi-cylindrical guide 12 and reaching the winding shaft 13 to bring the two together. When the clamper 18 is rotated while being sandwiched between the clamper 18 and the clamper 18 and the separable semi-cylindrical member 15, the fixed semi-cylindrical member is fixed.
A part of the clamper 18 protrudes from the groove 17 provided in the groove 14, and the space between the clamper 18 and the separable semi-cylindrical member 15 is narrowed, the packing materials 10 and 11 are clamped together, and the clamper 18 is further rotated to make contact. The separable semi-cylindrical member 15 rotates about the shaft 151, and the tubular body formed by the outer envelope surface of the fixed semi-cylindrical member 14 and the separable semi-cylindrical member 15 expands.

It should be noted that the packaging material 1 is set within the protrusion limit of the clamper 18.
The rotation limit of the semi-cylindrical member 15 which can be contacted and separated is provided so that the pressing force for holding 0 and 11 is sufficient.

In this state of being sandwiched, the winding shaft 13 is rotated to wind the packaging material. The winding shaft 13 can be rotated by a known means such as an electric motor M.

In FIG. 5, the open portion 12 of the semi-cylindrical guide 12 is shown.
No. 1 is located toward the partial boundary 101 where the packaging materials 10 and 11 from which the treatment agent package 50 has been peeled off are still attached, and has an opening sufficient to receive the treatment agent T. The treating agent T sealed between the wrapping materials 10 and 11 is released, enters the opening 121, and falls through the inside of the semi-cylindrical guide 12. The processing agent drops into the processing tank 1 through the opening at the lower end of the semi-cylindrical guide 12.

When the winding of the packaging materials 10 and 11 progresses and all the processing agents T of the series of processing agent packages 50 have been dropped, the clamper 18 is rotated in the opposite direction to the previous steps. When the semi-cylindrical that can be contacted and separated is released and the pressure is restored,
The tubular body formed by the outer shape envelopment surface is contracted, and a gap is formed between the tubular body formed by the wrapped packaging material and the inner diameter of the tubular body, so that the tubular body is easily extracted.
The operation of the clamper is shown in FIG. In the figure, the alternate long and two short dashes line shows the semi-cylindrical member 15 at the time of clamping.

Next, referring to FIGS. 6, 7 and 8, the packaging material 10,
A twin-screw replenishing device for winding 11 separately is shown.
6 is a perspective view of the take-up drop section, FIG. 7 is a perspective view of the take-up drop section in which the take-up shaft is inclined, and FIG. 8 is a plan view showing another embodiment of the take-up drop section. Winding shaft 13 for packaging materials 10 and 11, respectively
In this case, the peeling boundary portion 101 moves in accordance with the winding outer diameter as the winding progresses, so that the position where the processing material falls is changed. When it is desired to set the drop port small, it is preferable to provide a peeling roller 181 as shown in FIG.

Next, referring to FIG. 7, there is shown an embodiment of a biaxial winding system in which the winding shaft is inclined. This example is different from the above-described biaxial winding, in that one of the packaging materials 11 is started to be wound first, and the other packaging material 10 is wound after separating a space for dropping the treatment agent T. . This method is particularly effective when the treatment agent stored in the bulging portion 501 of the packaging material 10 is a tablet, and has a preferable effect for identifying the dropping position, but granules and powders But it is applicable. Also in FIG. 7, a peeling roller 181 is provided in order to prevent the boundary portion 101 from changing due to the outer shape becoming thicker as the winding by the winding shaft 132 progresses. It should be noted that no peeling roller may be provided for the take-up shafts 131 at the separated positions, as this does not cause a change in the boundary portion 101. However, in this embodiment, the roller 19 for pressing the winding outer diameter is biased by the spring 20.

FIG. 8 is a plan view showing a development of the two-axis winding system shown in FIG. 6, in which a grid 21 is provided in parallel with the winding shafts 131 and 132, and the grid 21 and the winding shaft are combined. Or a winding method in which the tip of the packaging material 10 or the packaging material 11 is sandwiched between lattices,
It does not come off due to the torque for winding, and the pinching of the tip is easily released when rewinding. In the embodiment shown in FIG. 8, the processing agent package 50 has the rewinding shaft 22 capable of operating the rewinding means provided in the processing agent container 5 and the rear end of the processing agent package 50 fixed to each other. After releasing the treating agent, the rewinding means is engaged with the rewinding shaft 22 to operate and rewind, thereby collecting the packaging material emptied in the case as the treating agent container and removing it together with the case. Convenient for disposal.
