[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic processing apparatus provided with a carrier for changing a posture of a photosensitive material conveyed from an upstream side and conveying it to a downstream side.

[0002]

2. Description of the Related Art Conventionally, in a photographic processing apparatus, the photosensitive material is sequentially drawn out from a magazine in which a long sheet-shaped photosensitive material in a roll shape is housed and cut into a predetermined length. The cut photosensitive material is exposed in the exposure processing section, then developed in the development processing section, and the wetness of the development processing is dried in the drying processing section to obtain a print. The transport system is arranged so as to sequentially communicate with the exposure processing section, the development processing section, and the drying processing section from the magazine.

Further, in recent years, the photographic processing apparatus is often constructed as a structurally independent unit in order to facilitate disassembling for assembly and maintenance at the time of manufacture, and particularly in the transport system. In that case, since it is arranged around the entire region in the apparatus, there is a strong tendency to divide the transport system into appropriate units and unitize them.

For example, as shown in FIG. 7, a printer section A accommodating an exposure processing unit (not shown) which is the exposure processing section, a development processing unit (not shown) which is the development processing section, and a drying section. A connecting section C connecting a processor section B accommodating a drying unit (not shown) which is a processing section (provided that the printer section A, the processor section B and the connecting section C are connected to each other).
Is the same housing), receives the photosensitive material carried out through the first transport path on the upstream side after the exposure processing in the exposure processing section is completed, and moves the photosensitive material from the lower side to the upper side so that the processor section B A transport unit 50 for feeding into the second transport path of the developing processing unit located at the upper position is housed. In addition, from the viewpoint of maintenance and the like, the transport unit 50 installed inside the connecting portion C is housed so as to be able to be pulled out independently of other transport systems such as the first transport path and the second transport path.

An exposure head for exposing the emulsion surface of the light-sensitive material is provided in the exposure unit. Such an exposure head irradiates the light-sensitive material with light from a light source through an optical shutter made of a PLZT element. While the light-sensitive material is being conveyed, the light-exposure head is in a direction orthogonal to the conveying direction of the light-sensitive material based on image data. A so-called scanning exposure method is employed in which line-shaped exposure is sequentially performed.

The transport unit 50 is aligned and transported in a substantially horizontal state in the first transport path of the printing section A so that the throughput of the developing process of the subsequent process corresponds to the throughput of the exposure process of the previous process. In order to distribute each of the plurality of photosensitive materials coming into the conveying direction into two rows on the right and left sides and convey them to the pair of second conveying paths in the parallel state of the processor section B, a pair of conveying mechanisms having a mirror image relationship is provided inside. I have it.

One of the pair of transfer mechanisms (hereinafter referred to as the first lane transfer mechanism) has a structure as shown in FIG.
It is composed of a rail 51 arranged in the up-down direction and a carrier body 52 for carrying the photosensitive material P along the rail 51.

The carrier 52 is vertically reciprocating along a rail 51, and a lateral reciprocating body 53 attached to the reciprocating body 53 so as to reciprocate in a direction orthogonal to the rail 51. The reciprocating body 54 and the end portion (end portion on the conveying direction side) of the photosensitive material P conveyed in a substantially horizontal direction from the printer section A (upstream side) are sandwiched, and the photosensitive material P is erected substantially vertically. It is composed of a sandwiching body 55 for holding.

The holding body 55 is a pair of holding plates 56a and 56b which hold the front and back sides of the photosensitive material P in close contact with each other.
And a pair of roller bodies 5 pivotally attached to each of the sandwiching plates 56a and 56b and abuttingly arranged through openings 57 formed in each of the sandwiching plates 56a and 56b.
8, 58 and. Further, the holding body 55 is
At the receiving position for receiving the photosensitive material P conveyed on the first conveying path, the pair of sandwiching plates 56a, 56b are tilted in the horizontal direction, and after sandwiching the photosensitive material P, they are configured to stand upright in the vertical direction. There is. It should be noted that the carrier 52 is a rail
When the pair of holding plates 56a and 56b are tilted in the horizontal direction at the lower limit of the above, the surface (conveying surface) between the pair of holding plates 56a and 56b and the photosensitive material P of the first conveying path passes through. The heights are the same, and the pair of holding plates 56 are set to receive the photosensitive material.

The other transport mechanism (hereinafter referred to as the second lane transport mechanism) is arranged symmetrically to the one transport device with respect to the center line of the first transport path in the width direction, and has the configuration of the first transport device. It is similar to the lane transport mechanism.

The operation of the pair of transport mechanisms having the above structure will be described with reference to the time chart shown in FIG.

First, while tilting the pair of holding plates 56a and 56b so that the pair of holding plates 56a and 56b are in a horizontal state, the pair of holding plates 56a and 56b are exposed from a predetermined standby position on the rail 51 of the first lane transfer mechanism. The reciprocating body 53 moves to the receiving position for receiving the material (a). Then, when the photosensitive material P is fed between the pair of holding plates 56a and 56b located at the receiving position, the photosensitive material P is transferred to the pair of roller bodies 58.
After being wound at a low speed for a predetermined time (d), it is wound at a high speed for a predetermined time (e).

Then, the photosensitive material P is sandwiched between the pair of sandwiching plates 56a and 56b, and the pair of sandwiching plates 56a and 56b are erected. Then, the reciprocating body 52 and the lateral reciprocating body 54 are respectively attached to one of the processor section B. And moved so as to correspond to the delivery position of the photosensitive material in the second conveyance path of (b).
After that, the nipping of the photosensitive material P by the nipping plates 56a and 56b is released, and the pair of roller bodies 58 are rotated to feed the photosensitive material P to the second conveying path of the processor section B. After feeding the photosensitive material P, the reciprocating body 53 is moved to the standby position (c), and the reciprocating body 53 of the second lane transport mechanism, the sandwiching body 55, and the like are prevented from interfering with each other at the standby position. stand by.

On the other hand, the reciprocating member 53 of the second lane transfer mechanism.
Stands by at a predetermined standby position on the rail 51, and the reciprocating body 53 of the first lane transport mechanism moves toward the second transport path of the processor section B (b), and after a lapse of a predetermined time, the first lane. When there is no interference with the reciprocating body 53 of the transport mechanism, it moves downward and the lateral reciprocating body 54 moves so that the holding body 55 is placed at the receiving position (a '). The pair of holding plates 56a and 56b are tilted in the horizontal direction simultaneously with the downward movement of the reciprocating body 53.

Similar to the first lane transport mechanism, when the photosensitive material P is fed between the pair of holding plates 56a and 56b, the photosensitive material P is wound around the pair of roller bodies 58 at a low speed for a predetermined time. After (d '), it is wound at a high speed for a predetermined time (e'). After that, the pair of holding plates 56a, 5
6b sandwiches the photosensitive material P, and a pair of sandwiching plates 56a, 56
After erecting b, the reciprocating body 52 and the lateral reciprocating body 54
(B ') so as to correspond to the delivery position of the photosensitive material on the other second conveyance path of the processor section B (b'), and then the photosensitive material P by the holding plates 56a and 56b.
And the pair of roller bodies 58 are rotated to feed the photosensitive material P to the second transport path of the processor section B.

After feeding the photosensitive material P, the reciprocating body 53 is moved to the standby position (c ') to prevent interference with the reciprocating body 53, the sandwiching body 55 and the like of the first lane transport mechanism. Stand by at the standby position. In addition, the reciprocating body 53 waiting on the rail of the first lane transport mechanism
Starts moving at substantially the same timing as the reciprocating body 53 of the second lane transport mechanism operates, and moves to the receiving position.

As described above, the photosensitive material is conveyed by the respective conveying bodies 52 of the first lane conveying mechanism and the second lane conveying mechanism, so that the photosensitive material conveyed in one row in the first conveying path is divided into two rows ( It can be sorted into (parallel) and transported to a pair of second transport paths connected to the development processing section.

[0018]

However, as described above, the sandwiching body 55 of the carrier body 52 moving in the direction orthogonal to the carrying direction of the first carrying path is the photosensitive material carried in the first carrying path. Since it is configured to be sandwiched by being fed into the sandwiching body 55, the photosensitive material cannot be delivered to the receiving position unless the sandwiching body 55 is arranged at the receiving position for receiving the photosensitive material. That is,
When the photosensitive material is sent to the receiving position when the holding body 55 is not located at the receiving position, the carrying body 52 is nipped when the carrying body 55 moves from the second carrying path side toward the first carrying path. The lower part of the body 55 interferes with the upper surface of the photosensitive material sent to the receiving position, and the sandwiching body 55 cannot receive the photosensitive material.

Therefore, the conveyance of the photosensitive material P is performed by the holding member 55.
In order to correspond to the arrangement timing of, the conveyance of the succeeding photosensitive material P is stopped for a predetermined time before the exposure processing so that the succeeding photosensitive material P does not reach the receiving position by the time the gripping body 55 is arranged at the receiving position. The photosensitive material P is conveyed with a space provided between the preceding photosensitive material P and the subsequent photosensitive material P. That is, due to the nature of the scanning exposure method, the conveyance of the photosensitive material P cannot be stopped or the conveyance speed cannot be changed during the exposure, so that the timing at which the photosensitive material P is positioned at the receiving position (conveyance speed of the photosensitive material P ) And the timing at which the nipping body 55 is placed at the receiving position (the operating time of the transport device), the plurality of photosensitive materials P must be transported at intervals.

As a result, even though the exposure processing section can continuously expose the photosensitive material P, a plurality of photosensitive materials P are intermittently conveyed, so that the exposure processing capability of the exposure processing section is utilized to the maximum. I couldn't. Also in the development processing section, the photosensitive material exposed by the exposure processing section, which has not been drawn to the maximum processing capacity, is conveyed by the conveying device, so that it can be compared to the maximum processing capacity of the exposure processing section. Even if the development processing section is configured to do so, the development processing capability cannot be fully utilized.

Therefore, in view of the above situation, the present invention depends on the operation timing of the carrier even when the photosensitive material carried on the upstream first carrier path is continuously carried to the receiving position. An object of the present invention is to provide a photographic processing apparatus provided with a carrier that can receive the photosensitive material without changing the position and can transport the photosensitive material to the second transport path on the downstream side by changing the posture. .

[0022]

[Means for Solving the Problems] In order to solve the above problems,
The photographic processing apparatus according to the present invention is as described in claim 1.
The posture of the sheet-shaped photosensitive material conveyed along the conveying surface of the first conveying path is changed in a direction intersecting the conveying direction of the first conveying path and intersecting the conveying surface, and the posture is changed. In a photographic processing apparatus including a carrier for sandwiching a photosensitive material and transporting the photosensitive material to a second transport path that intersects the transport direction of the first transport path and intersects the transport surface, the end of the first transport path. A supporting member for supporting one surface of the photosensitive material conveyed on the first conveying path, and the conveying member presses the other surface of the photosensitive material located on the downstream side from the supporting member, A pressing body for changing the posture of the photosensitive material so as to sandwich both sides of the photosensitive material with the support; and a sandwiching body for sandwiching the photosensitive material whose posture is changed by the pressing body. It is configured to be movable in a direction intersecting and intersecting with the transport surface. And wherein the Rukoto. The transport surface refers to a predetermined path through which the photosensitive material to be transported passes. For example, in the case where the transport path is one in which a plurality of roller pairs that sandwich the photosensitive material are intermittently arranged, An imaginary surface connecting the rollers of a roller pair and the rollers of a downstream roller pair adjacent to the roller pair.

According to the photographic processing apparatus having the above structure, the photosensitive material is rotated about the support by pressing the other surface of the photosensitive material located at the receiving position (downstream from the support) for receiving the photosensitive material. Or to bend and change the posture, and at the same time, sandwich the support and the pressing body, and then sandwich the photosensitive material whose posture is changed by the sandwiching body so that the photosensitive material is not directly sandwiched by the sandwiching body. Therefore, when the carrier is not located at the receiving position for receiving the photosensitive material on the first transport path, even if the photosensitive material reaches the receiving position and extends from the support to the downstream side, The photosensitive material can be reliably received. Therefore, the photosensitive material can be continuously transported (sent out) to the receiving position without being influenced by the timing at which the transport body is disposed at the receiving position for receiving the photosensitive material. Thereby, each of the plurality of photosensitive materials can be continuously conveyed in a state where they are brought close to each other in the first conveying path.

Therefore, if the first transport path is formed in the exposure processing section in the previous step where the exposure process is performed while the photosensitive material is transported at a constant speed, a plurality of photosensitive materials can be exposed without being influenced by the operation timing of the transport body. The exposure processing can be performed while the materials are conveyed in a state of being brought close to each other, and the processing capacity of the exposure processing unit can be utilized to the maximum. In addition, if the second transport path is formed in the developing processing section, the first transport path is formed, and the photosensitive material exposed in the exposure processing section that maximizes the processing capacity is used as the transport material. Since it is conveyed to the development processing section via the processing section, the processing capacity of the development processing section can be maximized corresponding to the normal processing capacity of the exposure processing section. Therefore, the processing capacity of the entire photographic processing apparatus can be improved.

Further, since the posture of the photosensitive material is changed by pressing the photosensitive material, a mechanism for changing the posture of the photosensitive material, for example, a mechanism for raising a sandwiching body for sandwiching the photosensitive material is unnecessary. As a result, the device can be simplified and the cost can be reduced.

According to a second aspect of the present invention, at least one of the support body and the pressing body is a roller body that is substantially parallel to the transport surface and is rotatable about an axis intersecting the transport direction. Then, it is possible to absorb the slip between the photosensitive material and the supporting portion or the photosensitive material and the pressing portion, which occurs when the other surface of the photosensitive material is pressed by the pressing body, by the rotation of the roller body. In particular, it is possible to prevent the image formed on the emulsion surface of the light-sensitive material from being damaged.

Further, according to a third aspect of the present invention, either one of the support body or the pressing body is substantially parallel to the transport surface, and the drive roller body is rotationally driven around an axis in a direction intersecting with the transport direction. When the other is composed of a driven roller body that is driven by the drive roller body via a photosensitive material, the drive roller body is rotated when the photosensitive material is sandwiched between the drive roller body and the driven roller body. In this case, the photosensitive material can be drawn in, a gap can be formed with the succeeding photosensitive material, and the operating time of the carrier can be further increased.

If the drive roller body is configured to be switchable between forward and reverse rotations, the photosensitive material drawn by the drive roller body and the driven roller body can be moved in a direction opposite to the drawing direction. Can be sent out. Therefore, it is possible to carry the sheet according to the layout of each device in the photographic processing device.

Further, if the sandwiching body is provided with a pair of sandwiching roller bodies for sandwiching both sides of the photosensitive material, the sandwiched sandwiching roller body for sandwiching the posture-changed photosensitive material. Even if a photosensitive material nipped by a device located downstream or a feeding system is drawn to the downstream side, the friction of the drawing roller due to the rotation of the nip roller body is absorbed. Therefore, it is possible to prevent a situation in which the light-sensitive material (especially the emulsion surface on which an image is formed) is damaged. Further, if the sandwiching roller body is configured to be rotatable, the photosensitive material can be sent out in accordance with the rotating direction of the sandwiching roller body.

Further, as described in claim 6, the sandwiching body may be provided so as to be movable in a direction orthogonal to the moving direction of the carrier. By doing so, by operating the sandwiching body, for example, even when a pair of second transport paths are provided in parallel, the pair of photosensitive materials transported on the first transport path It can be sorted and transported to each of the second transport paths. Further, if the transporting members thus configured are symmetrically arranged with respect to the moving direction of the transporting members, and the sandwiching members alternately transport the photosensitive material to the second transporting path, the transporting capacity is further improved. be able to.

That is, the drive roller body 18 in the photosensitive material P, which is sandwiched by the roller pair 12 of the exposure processing apparatus 1 in the vicinity of the other end and is supported by the drive roller body 18 on the downstream side.
Since the pressing driven roller body 39 presses the downstream side of
The photosensitive material P is bent with the driving roller body 18 as a fulcrum, and the bent photosensitive material P is sandwiched between the pressing driven roller body 39 and the driving roller body 18.

At this time, since the trailing end of the photosensitive material P is exposed by the exposure processing device 1 for a predetermined time after the pressing driven roller body 39 starts pressing the photosensitive material P, exposure blur is prevented. Therefore, the drive roller body 18 is rotated at a low speed, and the photosensitive material P, which is in the sandwiched state, is moved in the direction orthogonal to the transport surface of the first transport path X in a state corresponding to the transport speed on the first transport path X. Wind up (b).

When the exposure of the trailing edge of the photosensitive material P is completed, as shown in FIG. 5C, the driving roller body is arranged so that the trailing edge of the photosensitive material P is not located on the first conveying path X. 1
8 accelerates the rotation speed to further wind up the photosensitive material P at a high speed for a predetermined time (e). As a result, a gap is formed between the preceding photosensitive material P that has been wound up and the subsequent photosensitive material P that has been conveyed adjacently, and it is possible to allow the conveying ability of the conveying device 4 to have a margin.

Thereafter, as shown in FIG. 5D, the driving roller body 18 is reversed at a high speed so that the rear end of the photosensitive material P is nipped.
It is inserted between the pair of sandwiching plates 37a and 37b (3) (f). At this time, the photosensitive material P bent by the pressing of the pressing driven roller body 39 may be curled in a curved shape, but the lower end of one guide plate 37a is separated from the other guide plate 37b. Since it is bent as described above, it is guided between the pair of guide plates 37a and 37b while abutting on the lower end portion of the one guide body 37a whose distance is widened. Then, the photosensitive material P is fed until the rear end of the photosensitive material P projects from the upper ends of the pair of guide plates 37a and 37b, and the sandwiching driving roller body 33 and the sandwiching driven roller body 3 are fed.
The photosensitive material P is sandwiched by 8 and. In this state, the succeeding photosensitive material P has a space from the preceding photosensitive material P, and therefore has not yet reached the drive roller body 18.

Then, as shown in FIG. 5E, the photosensitive material P sandwiched by the sandwiching driving roller body 33 and the sandwiching driven roller body 38 is positioned at a position corresponding to one of the second transport paths Y. Then, the reciprocating body 21 is moved upward along the rail 19, and the lateral reciprocating body 22 is moved to the second rail 2.
Move along 7 (b).

When the transport body 20 reaches the delivery position where the photosensitive material P is delivered to the one second transport path Y, the gear 35 of the shaft body 34 pivotally supported by the horizontal reciprocating body 22 is connected to the connecting portion C.
The photosensitive material P, which is held between the holding driving roller body 33 and the holding driven roller body 38, meshes with the driving gear separately provided therein and is rotated. And the delivery of the photosensitive material P is completed.

Then, the reciprocating body 21 is moved downward along the rail 19 to make the carrier 20 stand by again at the waiting position.

On the other hand, in the second lane transport mechanism 17, the transport body 20 of the first lane transport mechanism 17 receives the photosensitive material P from the first transport path X, and from the receiving position toward the second transport path Y. By the time it moves, the transfer of the photosensitive material P to the other second transport path Y is completed, and it stands by at a standby position provided at a predetermined position on the rail 19 of the second lane transport mechanism 17.

Then, the carrier 20 of the first lane carrier mechanism 17 receives the photosensitive material P from the first carrier path X, moves toward the second carrier path Y, and after a lapse of a predetermined time, is exposed and is exposed downstream. The subsequent photosensitive material P conveyed to the side,
After reaching the drive roller body 18,
When the leading end of the photosensitive material P extends to the downstream side of the second lane transport mechanism 1, as in the operation of the first lane transport mechanism 17.
The horizontal reciprocating body 22 of the carrier 20 located at the standby position provided at the predetermined position on the rail of No. 7 makes it possible to position the sandwiching body 23 at a position corresponding to the first carrier path X. After moving along the rail 27, the reciprocating body 21 moves downward along the rail 19, and as shown in FIG.
The pressing driven roller body 39 of the sandwiching body 23 is the exposure processing apparatus 1
The upper surface (emulsion surface) which is the other surface located downstream of the drive roller body 18 of the photosensitive material P conveyed in a sandwiched state by the roller pair 12 on the downstream side of the photosensitive material P is pressed, While bending so as to follow the outer peripheral surface of the drive roller body 18, the photosensitive material P is brought into a sandwiched state together with the drive roller body 18 supporting the other surface of the photosensitive material P (a ′).

That is, the drive roller body 18 in the photosensitive material P, which is sandwiched by the roller pair 12 of the exposure processing apparatus 1 in the vicinity of the other end and is supported by the drive roller body 18 on the downstream side.
Since the photosensitive material P is bent on the driving roller body 18 as a fulcrum, the bent photosensitive material P is pressed by the pressing driven roller body 39 and the driving roller body 18.
It is sandwiched between and.

At this time, since the trailing end of the photosensitive material P is exposed by the exposure processing device 1 for a predetermined time after the pressing driven roller body 39 starts pressing the photosensitive material P, it is necessary to prevent the exposure blur. , The drive roller body 18 is rotated at a low speed, and the photosensitive material P in a sandwiched state is wound in a direction orthogonal to the transport surface of the first transport path X in a state corresponding to the transport speed on the first transport path X. Take (b ').

When the exposure of the trailing edge of the photosensitive material P is completed, as shown in FIG. 5C, the driving roller body is arranged so that the trailing edge of the photosensitive material P is not located on the first conveying path X. 1
8 accelerates the rotation speed to further wind up the photosensitive material P at a high speed for a predetermined time (e '). As a result, the succeeding photosensitive material P that has been conveyed adjacent to the preceding photosensitive material P that has been wound up is conveyed.
And a space is formed, and the carrying capacity of the carrying device 4 can be further increased.

Thereafter, as shown in FIG. 5D, the drive roller body 18 is reversed at a high speed so that the rear end of the photosensitive material P is held by the holding body 2.
It is inserted between the pair of sandwiching plates 37a and 37b of No. 3 (f '). At this time, the photosensitive material P bent by the pressing of the pressing driven roller body 39 may be curled in a curved shape, but the lower end of one guide plate 37a is separated from the other guide plate 37b. Since it is bent as described above, it is guided between the pair of guide plates 37a and 37b while abutting on the lower end portion of the one guide body 37 whose distance is widened. Then, the photosensitive material P is fed until the rear end of the photosensitive material P projects from the upper ends of the pair of guide plates 37a and 37b, and the sandwiching driving roller body 33 and the sandwiching driven roller body 3 are fed.
The photosensitive material P is sandwiched by 8 and. In this state, the succeeding photosensitive material P has a distance from the preceding photosensitive material P, and therefore has not yet reached the drive roller body 18.

Then, as shown in FIG. 5E, the photosensitive material P sandwiched by the sandwiching driving roller body 33 and the sandwiching driven roller body 38 is positioned at a position corresponding to the other second transport path Y. Then, the reciprocating body 21 is moved upward along the rail 19, and the lateral reciprocating body 22 is moved to the second rail 2.
Move along 7 (b).

When the transport body 20 reaches the delivery position where the photosensitive material P is delivered to the other second transport path Y, the gear 35 of the shaft body 34 pivotally supported by the horizontal reciprocating body 22 is connected to the connecting portion C.
The photosensitive material P, which is held between the holding driving roller body 33 and the holding driven roller body 38, is meshed with the driving gear separately provided therein and is rotated by rotating the driving gear. And the delivery of the photosensitive material P is completed.

Then, the reciprocating body 21 is moved downward along the rail 19 to make the carrier 20 stand by again at the waiting position.

In this way, the first lane transfer mechanism 17
By alternately operating the second lane transport mechanism 17, the photosensitive material P that has been subjected to the exposure processing and transported on the first transport path X is transported to the pair of second transport paths Y on the downstream side by changing its posture. To do.

As described above, in the transport device 4 of the photographic processing apparatus according to this embodiment, one surface (lower surface) of the photosensitive material P being transported on the transport surface of the first transport path X is driven by the drive roller body 18. While supporting and pressing the other surface (emulsion surface) of the photosensitive material P located downstream of the drive roller body 18 by the pressing driven roller body 39, the posture of the photosensitive material P is changed and sandwiched. Since the photosensitive material whose posture has been changed is sandwiched by the sandwiching body 23, the transporting body 20 does not need to stand by at the receiving position corresponding to the first transporting path X in advance and is transported in the first transporting path X. Even when the photosensitive material P to be formed exceeds the end of the first transport path X, the photosensitive material P can be transported to the second transport path Y while changing its posture.

Therefore, the first conveyance path X of the printer section A is
Even if a plurality of photosensitive materials P to be exposed are conveyed in a state of being adjacent to each other, these photosensitive materials P can be smoothly conveyed in the second conveying path Y.
Since it can be transported to, it is possible to maximize the processing capacity of the exposure processing apparatus 4 and the development processing apparatus 2,
The processing capacity of the entire photographic processing device can be improved.

Further, as is clear from a comparison between the time chart of the conventional transport device (FIG. 9) and the time chart of the transport device 4 according to the present embodiment (FIG. 6), the conventional transport mechanism has the standby position. To the receiving position and waits for the photosensitive material to be conveyed at the receiving position, and then receives the photosensitive material (FIG. 9A), the conveying device 4 according to the present embodiment waits. Since it only moves from the receiving position to the receiving position and receives the photosensitive material at the receiving position (FIG. 6A), the waiting time at the receiving position is not required and the moving from the receiving position toward the second transport path Y starts. You can speed up the timing. Therefore, the operating time of the transport device 4 can be shortened and the transport capability can be improved.

When the photosensitive material P sandwiched between the driving roller body 18 and the pressing driven roller body 39 is subjected to the exposure processing, the driving roller body 18 is rotated at a low speed so as to correspond to the exposure speed, and the photosensitive material P is exposed. Since the material P is wound up, even if the posture of the photosensitive material P is changed during the exposure, the exposure process is hardly affected.

Further, since the photosensitive material P which has undergone the exposure processing is wound up at a high speed, a space can be provided between the photosensitive material P and the succeeding photosensitive material P which is being exposed, and the carrying capacity of the carrying device 4 has a margin. Can be made.

Further, since the pressing body is the rotatable pressing driven roller body 39, even if the driving roller body 18 rotates and the photosensitive material P is wound up, the pressing driven roller body 39 passes through the photosensitive material P. By following the drive roller body 18, it is possible to prevent the image formed on the emulsion surface of the photosensitive material P from being damaged.

Further, since the photosensitive material P whose posture has been changed is sandwiched by the sandwiching drive roller body 33 and the sandwiching driven roller body 38 which can be driven to rotate, the photosensitive material P is guided to the second transport path Y. Can be delivered smoothly.

The photographic processing apparatus of the present invention is not limited to the above-mentioned embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

In the present embodiment, the drive roller body 18 which is a support is rotatably driven to draw in the photosensitive material, but the drive roller body 18 does not necessarily have to be rotatably driven, and for example, the drive roller body 18 is used. Alternatively, the pressing driven roller body 39 may be configured to be rotatable, and the photosensitive material may be pushed between the driving roller body 18 and the pressing driven roller body 39 by the conveyance of the first conveying path X.

In this embodiment, the pressing member and the supporting member are roller members (driving roller member 18, pressing driven roller member 39).
However, the pressing body and the supporting body do not necessarily have to be roller bodies as long as they can support or press the photosensitive material P without damaging the emulsion surface of the photosensitive material P. In this case, a coating having a small friction coefficient is applied to the portions of the pressing body and the support that come into contact with the photosensitive material,
For example, it is preferable to apply a fluororesin coating.

Further, one of the pressing body and the supporting body is a roller body, and the other is supporting or pressing the photosensitive material P,
Even if one roller body is configured to hold the photosensitive material P, the same operation and effect as in the present embodiment can be obtained. In this case, on the other hand, in order not to damage the emulsion surface of the photosensitive material P, it is preferable to apply a resin coating having a small friction coefficient, for example, to a portion contacting the photosensitive material P.

Further, the transport device 4 in this embodiment
Is composed of a pair of transport mechanisms 17,
Need not necessarily be provided as a pair, but may be a series of transport mechanisms 17 depending on the processing capacity of the photographic processing apparatus. Even in this case, if the lateral reciprocating body 22 is moved in the direction orthogonal to the rail 19, the photosensitive material P from the first transport path X can be distributed to two or more series of transport paths. That is, by increasing the moving distance of the horizontal reciprocating body 22 and setting two or more stop positions of the horizontal reciprocating body 22, even if two or more downstream conveying paths are provided, the first conveying path X can be provided. The photosensitive material P from can be conveyed in correspondence with the conveying path on the downstream side.

In the present embodiment, the drive roller body 18, which is a support, is driven to rotate, but the pressing driven roller body 39 is configured to be rotatable, and the drive roller body 1 is
8 may be configured to follow the pressing driven roller body 39. Further, each of the driving roller body 18 and the pressing driven roller body 39 may be rotationally driven to feed the photosensitive material P. In this case, it is preferable that the driving roller body 18 and the pressing driven roller body 39 rotate in synchronization with each other so as not to damage the emulsion surface of the photosensitive material P.

In the present embodiment, the transport device 4 is configured to transport the photosensitive material P upward.
It goes without saying that the arrangement of 9 allows the photosensitive material P whose posture has been changed to be conveyed downward.

Further, in the present embodiment, the reciprocating body 2
1 and the lateral reciprocating body 22 are moved by the rotating endless belt, the reciprocating body 21 and the lateral reciprocating body 22 are
Does not necessarily need to be moved with a rotating endless belt,
For example, the reciprocating body 21 and the lateral reciprocating body 22 can be moved even if a cylinder, a rack, and a pinion are adopted.

[0083]

As described above, as an effect of the present invention, by pressing the other surface of the photosensitive material which is located downstream from the support and is being conveyed, the posture of the photosensitive material is changed and the support is pressed at the same time. Since the photosensitive material whose position is changed is sandwiched between the photosensitive body and the body, the photosensitive material is not moved to the first position when the conveying body is not located at the receiving position of the first conveying path for receiving the photosensitive material. Even if the photosensitive material is extended to the downstream side from the support provided at the end of one conveying path, the photosensitive material can be surely changed in posture and received. Therefore, the photosensitive material can be continuously conveyed to the receiving position on the first conveying path without being influenced by the timing when the conveying body is arranged at the receiving position for receiving the photosensitive material, and the posture of the photosensitive material is changed. Can be reliably transported to the second transport path.
