DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacking tray for a photosensitive material processing apparatus which sequentially stores photosensitive materials which are processed by a processing solution in a photosensitive material processing apparatus, dried, and discharged.

[0002]

2. Description of the Related Art A photosensitive material on which an image has been printed is processed with a processing solution such as a developing solution, a fixing solution, or washing water, and then dried in a drying section. Examples of such a photosensitive material include a film in which a photosensitive layer is applied to the surface of a support such as PET. Some photosensitive material processing apparatuses for processing the photosensitive material are provided with a tray for storing the photosensitive material in a substantially horizontal state below an outlet from a drying unit. In a photosensitive material processing apparatus having such a tray, after being processed by the processing liquid, the dried photosensitive material is sent out from the outlet of the drying unit in a substantially horizontal state, and is sequentially stacked on this tray. It is to be accommodated.

[0003] On the upper surface of the tray, a plurality of elongated ribs are formed in the discharge width direction of the photosensitive material along the discharge direction of the photosensitive material, and the photosensitive material discharged from the discharge port is formed by these ribs. After being fed in contact with the tops of the ribs, they are supported and accommodated in contact with the tops of these ribs. Thereby, the photosensitive materials sent out from the discharge port are stacked and stored on the tray.

[0004]

However, when a large number of photosensitive materials are stacked on a tray, it is necessary to stack newly discharged photosensitive materials on the photosensitive material already placed on the tray. The newly discharged photosensitive material is conveyed while being in contact with the upper surface of the photosensitive material already placed on the tray. At this time, the photosensitive material charged with static electricity due to friction, peeling, and the like between a conveying roller such as a rubber roller in the drying unit and the photosensitive material is discharged from the discharge port, and is also newly added to the photosensitive material already placed on the tray. Static electricity due to friction occurs between the discharged photosensitive material and the already charged photosensitive material. For this reason, there arises a problem that the newly discharged photosensitive material and the photosensitive material already placed on the tray are stuck to each other, making it impossible to align and stack the photosensitive material in the tray. Even if the photosensitive materials (for example, about 50 sheets) are aligned and stacked one after another, they will not be uniform. Eventually, the discharge port of the drying unit will be blocked, and the photosensitive material may not be discharged properly. is there.

The present invention has been made in view of the above facts, and is intended to convert a photosensitive material discharged from a photosensitive material processing apparatus into a photosensitive material.
An object of the present invention is to provide a stacking tray of a photosensitive material processing apparatus capable of accommodating a large number of photosensitive materials by being stacked smoothly without sticking to each other.

Therefore, the newly discharged photosensitive material is
It moves to a predetermined position smoothly with little friction with the already placed photosensitive material. Because the friction during movement is small, it is possible to suppress the generation of static electricity between the newly discharged photosensitive material and the already placed photosensitive material, and to prevent the photosensitive material newly discharged from the discharge roller from being discharged. Even if the material is charged due to the generation of static electricity due to friction with a conveying roller such as a rubber roller in the drying section before being discharged from the discharge port, the photosensitive material can be smoothly stacked and stored on the tray. At the same time, it is possible to prevent the stacked photosensitive materials from sticking to each other.

For this reason, the photosensitive material placed on the tray is curved with the central portion protruding upward, and only the middle portion in the width direction of the leading end of the newly discharged photosensitive material is already loaded. Contact with the photosensitive material. Further, the guide portion provided on the tray guides the leading end of the newly discharged photosensitive material in a direction away from the already loaded photosensitive material.

According to claim 4 or claim 5 of the present invention,
If the photosensitive material is placed on the tray in a state where a part of the photosensitive material in the width direction protrudes upward, the tip of the newly discharged photosensitive material moves on the already placed photosensitive material. And the occurrence of static electricity due to friction can be suppressed, and a gap can be formed between the photosensitive material placed on the tray and the newly discharged photosensitive material. The photosensitive material can be moved smoothly, and static electricity is generated by friction between the photosensitive material that is newly sent out from the discharge roller and the transfer roller such as a rubber roller in the drying unit before it is discharged from the discharge port. Even if charged, the photosensitive materials can be smoothly stacked and stored on the tray.

I do.

As described above, the automatic developing apparatus 10 develops, fixes and rinses the film 20 and then performs a drying process. The film 20 dried in the drying unit 16 is nipped and conveyed by a pair of discharge rollers 60 and sent out from a discharge port 62. Film 2 sent out from outlet 62
No. 0 moves on the top of the rib 78 along the discharge direction (the direction of the arrow A) on the top of the rib 78 when the tip contacts the top of the rib 78 of the tray 64.

After that, the rear end of the film 20 is
2, the leading edge of the film 20 is
It reaches the projection 80 and is directed upward in the discharge direction by the projection 80. In this state, when the rear end of the film 20 is sent out from the outlet 62, the rear end of the film 20 falls on the inclined surface. At this time, the film 20 slides in a state of being slightly floated from the already mounted film 20 by the air that has entered the lower surface of the film 20 from the front end of the film 20 by the top of the film 20 being directed upward. After that, the leading end abuts on the inner surface of the tray frame 74, and the inclined surface 7
0. That is, it is placed in a state of being supported on the top of the rib 78 protruding from the inclined surface 70.

The films 20 stacked on the tray 64 in this way are adapted to the surface shape of the tray 64 and
The shape of the surface of the tray 64 is the same as the shape of the surface of the tray 64, for example, the portion of 0 becomes convex.

When a new film 20 (film 20A shown in FIG. 6A) is fed in this state, the leading end of the film 20A slides on the upper surface of the film 20 and moves downstream in the discharge direction. When the rear end of the film 20 </ b> A is discharged from the discharge port 62, the front end reaches the convex portion 80. As shown in FIG. 6B, when the rear end of the film 20A is discharged from the discharge port 62 and falls,
The leading end of A is directed upward in the discharge direction by the convex portion 80, and a gap is formed between the film A and the film 20 that has already been discharged and placed.

As a result, as shown in FIG. 6C, when an air layer is formed between the lower surface of the film 20A and the upper surface of the film 20 with the leading end of the film 20A floating from the film 20, the film 20A becomes The film 20A tries to fit into the tray frame 74 by the weight of the film 20A itself, and the spring force of the flexure generated by the weight of the film 20A itself causes the wall 66 forming the discharge port 62.
Of the film 20 by the propulsion generated by acting on the film 20
A moves so as to slide on the surface of the film 20 from the leading end portion, contacts the inner surface of the tray frame 74, and is placed on the upper surface of the film 20 with the leading ends aligned.

Thus, the automatic developing apparatus 10
And the film 20A discharged from the discharge port 62 is slid and moved on the upper surface of the uppermost film 20 already stacked on the inclined surface 70 of the tray 64. Can be stacked and housed. At this time, since the leading end of the newly discharged film 20A slides on the surface of the already discharged film 20, the static electricity is generated due to friction or the like when the leading end of the film 20A moves on the surface of the film 20. And the film 20A newly discharged from the discharge port 62 is charged by static electricity generated by friction with a transport roller such as a rubber roller in the drying unit 16 before being discharged from the discharge port 62. In order to smoothly move the film 20A to a predetermined position,
It can be stacked on the film 20 in order.

Further, if the films 20 stacked and housed on the tray 64 are stuck to each other, when the film 20 is to be taken out of the tray 64, the other films 20 remaining on the tray 64 due to static electricity are easily removed. However, such a problem can be prevented, although both surfaces cannot be peeled off or both surfaces are damaged when peeled off.

The rib 92 has a longitudinal direction formed along the discharge direction of the film 20, and a top portion is formed so as to be inclined downward from the discharge port 62 side along the discharge direction. Thus, the films 20 discharged from the discharge port 62 are stacked in a state where the films 20 are inclined so that the front ends thereof are directed downward.

At the leading end of the tray 90 in the film discharging direction, a bridge 94 is provided along the width direction.
The bridge 94 is arranged on the upper surface 90A of the tray 90 so that a metal plate such as stainless steel is bent and convex upward, and is adapted to the shape of the rib 92 so as not to interfere with the rib 92. A notch 94A is formed. As a result, when the rear end of the film 20 is discharged from the discharge port 62, the front end of the film 20 is guided upward by the bridge 94, and is interposed between the uppermost film 20 already stacked. A gap is formed.

As described above, the bridge 9 for forming the projection of the present invention is provided at a predetermined position of the tray 90 having a general shape.
By arranging the four, without impairing the beauty of the tray 90,
This makes it possible to form a tray with extremely good integration of the film 20.

In the first embodiment, the inclined surface 7 of the tray 64 is
0, the rib 78 and the convex portion 80 are formed, and the second embodiment has been described using the example in which the bridge 94 is arranged on the tray 90, but the present invention is not limited to this. For example,

The film 20 is guided in a direction away from the film 20.

As described above, by forming a convex or concave shape along the discharge width direction on the film 20 placed on the tray 64, the area where the newly discharged film 20A comes into contact with the already loaded film 20 is formed. And the contact resistance can be reduced, and a large gap can be provided between the film 20 and the film 20A. In addition, the tip of the film 20A has a protrusion 80 shown in FIG.
The tip of the bridge 94 or the rib 78 shown in FIG.
The film 20 is guided in a direction away from the film 20 already placed by the stairs formed by OA.

In this way, a large amount of air is sent between the film 20A and the film 20 to suppress the generation of static electricity between the film 20A and the film 20A. Film 2 on film 20 even if
OA can be stacked smoothly.

Further, in the present embodiment, the film 20 is used as the photosensitive material. However, other photosensitive materials such as photographic paper may be used. It is not limited to 10. For example, in the automatic developing apparatus 10, the film 20 discharged from the discharge port 60 of the drying unit 46 is placed on the tray 64 disposed above the processing liquid processing unit 18. Alternatively, the photosensitive material may be discharged in a substantially horizontal state and placed on a tray disposed adjacent to a discharge port provided on the opposite side to the above.

[0061]

As has been described above, the light-sensitive material processing of the present invention
The stacking trays of the processing device are formed so that an air layer is formed on the lower surface side of the photosensitive material when the photosensitive material is newly fed onto the upper surface of the already stacked photosensitive material, and the trays are slid, so that they are moved between each other. And the occurrence of sticking due to static electricity or the like can be prevented, and the photosensitive material can be smoothly fed to the upper surface of the uppermost photosensitive material and placed on the photosensitive material. Further, since the photosensitive material newly fed into the uppermost photosensitive material does not stick due to static electricity or the like, an excellent effect that it can be easily taken out can be obtained.
