2. Description of the Related Art A printing plate for printing a large amount of printed matter is prepared by exposing a printing plate according to a printing image. Also,
Prior to imagewise exposure of the printing plate, the plate is inspected for errors such as characters. Further, when performing color printing, it is necessary to perform plate inspection including whether there is an error in color.

A proof (color proof) formed by exposing a photosensitive material for plate inspection according to an image for printing is used for such plate inspection.

In recent years, due to the widespread use of DTP, a printing plate may be exposed by using image data for printing to form a printing plate. When producing a color proof prior to producing such a printing plate, an image exposure device that exposes a photosensitive material for plate inspection according to image data is output device (setter).
As the output device, there is used a color proof making device in which an automatic developing device (hereinafter, referred to as “processor”) for developing a photosensitive material is connected to the output device.

The processor is designed so that the photosensitive material fed from the output device is nipped and conveyed by a pair of rollers, and is immersed in a developing solution, a bleach-fixing solution and a rinsing solution or rinsing water in order for development processing.

By the way, in the processor, a processing rack provided with a plurality of guides and rollers is arranged in the processing tank, and the photosensitive material is guided and conveyed along a conveying path formed by the processing rack. ing.

In such a processing rack, a pair of rack side plates are connected in parallel by a plurality of shafts, and a guide member is assembled together with a plurality of rollers between the pair of side plates to convey a photosensitive material. Is generally formed.

Further, in a processor which processes a photosensitive material by immersing it in a processing solution stored in a processing tank, the photosensitive material is guided and conveyed in a substantially U-shape in the processing tank. In the processing rack, for example, a large-diameter reversing roller is arranged in the lower part of the processing rack, and small-diameter rollers are arranged on the lower side and the upstream side and the downstream side of the reversing roller. A guide member facing the circumferential surface of the reversing roller is arranged between them to form a turn portion.

As a result, when the photosensitive material is fed from above the reversing roller between the reversing roller and the upstream roller, it is guided and conveyed along the circumferential surface of the reversing roller, and the downstream roller and the reversing roller are separated from each other. It is sent upward from the space.

On the other hand, the guide member provided on the processing rack is formed, for example, by arranging guide plates on the shaft at predetermined intervals, and abutting both ends of the shaft in the axial direction against each of the pair of rack side plates, the rack side plate is formed. Is fixed by screwing a screw inserted from the outside into a screw hole formed at the tip of the shaft.

Further, since the processing rack is apt to be twisted at the turn portion, the guide member provided at the turn portion is 2
It is configured to be formed by using more than one shaft, and each shaft is firmly fixed by screwing to the rack side plate.

[0012]

However, in addition to the shaft connecting the pair of rack side plates, the shafts provided in each of the plurality of guide members are abutted against each of the pair of rack side plates to be assembled. In this case, the guide members arranged between the pair of side plates are twisted or shaken due to variations in the length of the shaft. For example, if there is a shaft longer than the distance between the pair of rack side plates, the middle portion of the shaft bends, which causes the guide member to be distorted or twisted.

The distortion or twist of the guide member causes a problem such as a defective conveyance of the photosensitive material.

The present invention has been made in view of the above facts, and it is an object of the present invention to propose a processing rack structure of an automatic developing apparatus in which a guide member or the like forming a conveyance path of a photosensitive material is not distorted. .

[0015]

In order to achieve the above object, the present invention is provided in an automatic developing tank for carrying and processing an image-exposed photosensitive material while being immersed in a processing solution stored in the processing tank. In the processing rack structure of the automatic developing device, which is arranged in the processing tank and forms a conveyance path for guiding and conveying the photosensitive material, the rollers arranged in pairs and rotatably arranged are rotatable. A supporting rack side plate, a connecting shaft that connects the pair of rack side plates and holds the pair of rack side plates at a predetermined interval, and a protrusion that is connected and fixed at one end to one of the pair of rack side plates and is formed at the other end. Is inserted into a support hole provided on the other side of the pair of rack side plates, and a guide member that is suspended and supported at a predetermined position of the pair of rack side plates.

According to the present invention, the pair of side plates are connected by the connecting shaft and are held at a predetermined interval. A roller for conveying the photosensitive material is hung between the pair of rack side plates and rotatably supported.

In the guide member arranged between the pair of rack side plates, a support hole into which the protrusion is inserted is formed in the rack side plate facing the protrusion of the guide member.

The guide member is fixed at a predetermined position between the rack side plates by fixing the end opposite to the protrusion to the rack side plate and inserting the protrusion into the support hole formed in the guide member and fitting the same. Supported.

As a result, the guide member is not pressed by the side plates when it is bridged between the pair of side plates, so that the distortion or the like caused by being pressed by the rack side plates does not occur.

Therefore, the defective conveyance of the photosensitive material will not occur due to the distortion of the guide member or the like.

As such a guide member of the present invention,
When the guide member includes a shaft having a predetermined length that is bridged between the pair of side plates and a guide plate that is arranged at a predetermined interval on the shaft, one end of the shaft in the axial direction is the pair of racks. The shaft may be fixed to one of the side plates, and the other end of the shaft may be inserted into a support hole formed in the other of the pair of rack side plates according to the outer shape of the shaft.

That is, according to the present invention, one end of the shaft projecting from the guide member is inserted into and fitted into a support hole formed in the rack side plate according to the outer diameter of the shaft. Is also good.

Further, in the present invention, a reduced diameter pin portion may be formed at the other end of the shaft, and the pin portion may be inserted into the support hole.

The processor 14 is connected to the setter 12, and the photosensitive material 22 sent from the discharge port 30 is sent to the insertion port 40 of the processor 14 facing the discharge port 30. In the processor 14, based on the carry-out signal from the setter 12, the pair of carrying rollers 44, 4 and
6 etc. are rotationally driven.

As a result, the insertion port 40 of the processor 14
When the photosensitive material 22 inserted from is fed into the space between the pair of transport rollers 44 arranged so as to face the insertion opening 40,
The conveying roller pair 44 holds the photosensitive material 22 and pulls it from the setter 12 into the processor 14.

The processor 14 is constituted by the conveying roller pair 44.
The photosensitive material 22 drawn into the inside is first sent to the processing liquid processing section 34 and conveyed while being immersed in the developing solution, the bleach-fixing solution and the rinsing solution in that order, and then subjected to the developing processing, the bleach-fixing processing and the rinsing processing. Processing is performed.

The photosensitive material 22 for which the rinsing processing has been completed is sent from the rinsing tank 62 to the drying section 36, and is conveyed inside the drying section 36 along the lower surface of the mesh belt 82. At this time, in the drying unit 36, the dry air generated by the dry air generating means (not shown) is supplied to the chamber 90 and is ejected from the ejection port 92 toward the photosensitive material 22.

As a result, the photosensitive material 22 is conveyed in the drying section 36 while being attached to the lower surface of the mesh belt 82, heated and dried by the dry air, discharged from the discharge port 74, and stored in the stocker 16. Accumulated.

By the way, in the processor 14, the developing tank 5
4. The processing racks 64, 66, 68A to 68C are arranged in the bleach-fixing tank 56 and the rinsing tanks 58 to 62 to form a conveyance path for the photosensitive material 22.

For example, in the processing rack 64 provided in the developing tank 54, the insertion roller pair 234 and the roller pair 210A, 210 are provided between the pair of rack side plates 200A, 200B.
B, reversing roller 204 and small roller 206, roller pair 21
2A, 212B and a pair of transport rollers 238 are arranged, and guide members 208, 214A, 214B, 216,
218, 224 to 228, 236 are provided to form a conveyance path for guiding and conveying the photosensitive material 22 in a substantially U shape.

On the other hand, in the processing rack 64, the pair of rack side plates 200A and 200B are connected to the connecting shafts 274 and 2.
The rack side plates 200A and 200B are connected to each other at regular intervals by a guide member 208, 2

It is pressed by 0B, and bending or the like occurs. The flexure of the shaft 284 causes a deviation in the guide plate 236A attached to the shaft 284, and causes variations in the side of the photosensitive material 22 facing the conveyance path.

Such deviation of the guide plate 236A and variation of the surface of the photosensitive material 22 on the conveying path side make it difficult to guide the photosensitive material 22 to an appropriate position. For this reason, a conveyance failure of the photosensitive material 22 such as jamming occurs.

In order to prevent such defective conveyance of the photosensitive material 22, it is necessary to process the shaft 284 with high accuracy, which leads to an increase in cost of the processing rack 64.

On the other hand, in the processing rack 64, a pin portion 288 is formed on one end side of the shaft 284 used for the guide member 236, and the pin portion 288 is used for the rack side plate 200.
The pin hole 296 formed in B is inserted and supported. Thereby, the pair of rack side plates 200
Since A and 200B do not press the main body shaft 286 of the shaft 284, the guide plate 236A attached to the shaft 284 will not be displaced or uneven.

Therefore, the rack side plates 200A, 200
The guide member 236 attached to the shaft B via the shaft 284 can guide the photosensitive material 22 toward the insertion roller pair 234 in a proper direction and in an appropriate state, and causes conveyance failure of the photosensitive material 22. There is no end.
Further, the guide member 2 which prevents the defective conveyance of the photosensitive material 22
36 can be manufactured at low cost.

In the processing rack 64, such a shaft 284 is used to guide the guide members 208, 214A, 214.
B, 216, 218, 224-228 to the rack side plate 20
Since it is attached to 0A and 200B, the guide member 20
8, 214A, 214B, 216, 218, 224-2
28 and 236 do not cause the defective conveyance of the photosensitive material 22, and the photosensitive material 22 can be properly guided along the predetermined conveying path.

In the processor 14, the processing rack 6
4, 66, 68A to 68C, the photosensitive material 22 can be smoothly conveyed and processed without causing a defective conveyance.

The above-described embodiment does not limit the structure of the present invention.
