Description

  The present invention relates to a photosensitive material delivery apparatus having a sorting and conveying unit capable of sorting exposed photosensitive materials supplied from an exposure processing unit in a single row into a plurality of rows and delivering them to a development processing unit.

As this type of photosensitive material delivery device, there is Patent Literature 1 shown below as prior art literature information related to the present invention. The photosensitive material delivery device described in Patent Document 1 has a holding plate arranged vertically, and a pair of conveying bodies supported on the left and right sides of the holding plate so as to be capable of reciprocating in the vertical direction, A movable body capable of reciprocating horizontally is supported on each of the pair of left and right transport bodies. Each moving body supports a swinging member that can swing around an axis along the width direction of the photosensitive material. Further, the swinging member has a gap for receiving the photosensitive material in between. A pair of chucking rollers facing each other is provided that can be switched between the formed release posture and the pressure-bonding posture for crimping the photosensitive material.
When, for example, the left conveyance body is lowered to a discharge level at which the photosensitive material is discharged from the exposure unit, the swing member is swing-operated based on contact with a contact operation member fixed to the holding plate. Therefore, the angle posture is switched by about 90 ° from the “horizontal posture” where the chucking roller pairs are lined up horizontally to the “accepting posture” where the chucking roller pairs are lined up and down. The chucking roller is switched to the release posture by the switching plate. In this state, when the photosensitive material sent in a horizontal posture with the emulsion surface facing upward is received between the chucking rollers (the photosensitive material is sent to the central portion of the holding plate in the width direction). Then, the chucking roller is switched to the pressure-bonding posture by the lowering of the switching plate, and the left conveyance body is subsequently raised toward the left introduction roller in the development processing section. Since the swinging member is released from the contact state with the contact operating member in the middle of the ascent, the swinging operation is performed to the “horizontal posture” based on the biasing force of the coil spring. That is, by this swinging operation, the photosensitive material sandwiched between the chucking rollers is exchanged between the front and back sides, and the emulsion surface is in a vertical posture facing the holding plate, and is transferred to the left introduction roller for development processing. The conveyance is started along the lane on the left side of the section. Next, the right transport body is lowered to the discharge level, and the next photosensitive material is received from the exposure unit. After passing through the same process as the left transport body, the next photosensitive material is moved to the right side. The photosensitive material is delivered to the introduction roller, and the photosensitive material is started to be conveyed along the right lane of the development processing unit. In this manner, the pair of left and right conveying bodies that reciprocate up and down alternately can distribute the photosensitive materials discharged from the exposure unit in a single row into two left and right rows and transfer them to the development processing unit.
That is, in this prior art photosensitive material delivery apparatus, the photosensitive material discharged from the exposure unit in a horizontal orientation is changed to a vertical orientation inverted by about 90 ° and then delivered to the introduction roller of the development processing unit. In this way, the front and back of the photosensitive material can be exchanged smoothly, and at the same time, at least when the photosensitive material is an L version with a relatively small width, the photosensitive material is arranged in two rows on the left and right (actually left and right Can be inserted into the development processing section (this sort operation is performed in order to increase the processing capability in the development processing section).
JP 2002-55400 A (paragraph numbers 0019 to 0021, 0023, 0027, 0029 to 0033, 0035, FIGS. 3 to 9).

  However, in the photosensitive material delivery device of Patent Document 1, the left and right moving bodies and the chucking rollers are separated from each other when they reciprocate up and down along the surface of the holding plate. It has a cantilever structure that extends from the respective carriers that move up and down in the vicinity of the end portion toward the center of the holding plate. As a result of such a cantilever structure, the chucking roller is likely to wobble around an axis that is perpendicular to the surface of the holding plate, or the photosensitive material is likely to rotate during clamping with respect to the chucking roller. Since the posture of the photosensitive material delivered from the king roller to the introduction roller is also unstable, there is a tendency for the longitudinal axis of the photosensitive material to be delivered to the development processing unit in a posture inclined with respect to the traveling direction of the photosensitive material. It was. If there is such a tendency, the development processing unit is transported in a state where the photosensitive materials adjacent to each other in the front and back are partially overlapped, or the finished print discharged from the drying unit is in an uneven state where the corners are not aligned well. There is a possibility of causing a result of being stacked on a sorter or the like.

  Accordingly, an object of the present invention is to develop the development processing unit in a posture in which the longitudinal axis of the photosensitive material is inclined with respect to the traveling direction of the photosensitive material in view of the above-mentioned drawbacks of the prior art photosensitive material delivery apparatus exemplified above. Therefore, it is possible to reduce the possibility that the photosensitive material will be transported through the development processing part with some overlapping of the photosensitive materials, and the finished prints discharged from the drying part will be stacked on the sorter in an uneven state. Another object is to provide a sensitive material delivery device.

A first characteristic configuration of the present invention is a photosensitive material delivery apparatus having a sorting and conveying unit capable of sorting exposed photosensitive materials supplied in a single row from an exposure processing unit into a plurality of rows and delivering them to a development processing unit. ,
The sorting and conveying unit is supported in a bilaterally supported manner so as to reciprocate between a receiving position for receiving the photosensitive material from the exposure processing unit and a delivery position for transferring the photosensitive material to a plurality of introducing portions of the developing processing unit. And a single laterally movable member capable of reciprocating left and right on either side of the plurality of introduction parts while sandwiching a photosensitive material,
Each of the introduction portions of the development processing unit includes a clamping member that clamps the passed photosensitive material, and a correction mechanism that corrects a portion of the photosensitive material that is located upstream of the clamping member in a curved shape. There is to be.

Therefore, in the photosensitive material delivery apparatus according to the first characteristic configuration of the present invention, the moving arm that reciprocates between the photosensitive material delivery position and the photosensitive material delivery position is supported by the frame member of the photosensitive material delivery apparatus. Since it is supported, neither the moving arm itself nor the lateral moving member supported by the moving arm is likely to wobble with respect to the frame member or the like, or the sensitive material sandwiched between the lateral moving members is also the lateral moving member. Therefore, the posture of the photosensitive material delivered from the laterally moving member to the introduction portion is further stabilized, and the photosensitive material is developed in a correct posture with the longitudinal axis extending in parallel with the traveling direction of the photosensitive material. As a result, the sorter is transported through the development processing unit with the photosensitive materials partially overlapping, or the finished print discharged from the drying unit is in an uneven state where the corners are not aligned well. Phenomena such as stacked in such is suppressed.
By the way, if the moving arm is simply left and right, the second half of the preceding photosensitive material delivered to one introduction part (the part on the second half is still upstream from the introduction part immediately after delivery). ), There is a risk of damage to the photosensitive material due to the moving arm coming to deliver the subsequent photosensitive material to the adjacent introduction part, so there is an excess in the front-rear direction between the preceding photosensitive material and the subsequent photosensitive material. It is necessary to keep a certain distance, resulting in a problem that the processing capacity cannot be increased. However, in the photosensitive material delivery device according to the first characteristic configuration of the present invention, the portion located upstream of the introduction portion of the photosensitive material is corrected in a curved shape by the correction mechanism, so that the second half side of the preceding photosensitive material is When the laterally moving member tries to deliver the succeeding photosensitive material to the other introducing portion with the upstream portion left from one introducing portion, the moving arm or the like comes into contact with the preceding sensitive material to remove the sensitive material. There is no risk of damage, and as a result, the speed of delivery of the photosensitive material to the introduction portion can be increased, and the processing speed is increased.

According to a second characteristic configuration of the present invention, the correction mechanism has an operation member having an action portion that contacts a predetermined portion of the photosensitive material and pushes the predetermined portion in a direction intersecting the surface of the photosensitive material, The operation member is displaced between an operation position where the action portion corrects the sensitive material in a curved shape and a retreat position where the action portion is retracted from the moving path of the sensitivity material sent to the introduction portion by the sorting and conveying unit. Further, the operating member is switched to the retracted position according to the approach of the sorting and conveying unit to the introducing portion, and the operating member according to the separation of the sorting and conveying unit from the introducing portion. A switching mechanism for switching the operation position to the operation position.
Therefore, in the photosensitive material delivery device according to the second characteristic configuration of the present invention, an operation member that pushes a predetermined portion of the photosensitive material through the contact is used as the correction mechanism, so that the configuration that can be realized easily and inexpensively, A correction mechanism that reliably curves the photosensitive material is obtained. Then, since the operating member is switched to the retracted position by the switching mechanism in accordance with the approach to the introducing portion of the sorting and conveying unit, the operating portion of the operating member does not hinder the path of the sensitive material delivered to the introducing portion. Is not damaged by the action part.

According to a third characteristic configuration of the present invention, the switching mechanism includes an urging mechanism that urges the operation member toward the operation position, and the operation member that moves the operation member according to the approach to the introduction portion of the sorting and conveying unit. And an auxiliary operation member provided in the sorting and conveying unit for switching to the retracted position.
Therefore, in the photosensitive material delivery device according to the third characteristic configuration of the present invention, the operating member is normally urged to the operating position by the urging mechanism, and the photosensitive material carried by the sorting and conveying unit contacts the operating member. By simply switching the operation member to the retracted position by the auxiliary operation member provided in the sorting and conveying unit at the previous timing, a correction mechanism that is very simple in structure and operates reliably is realized.

According to a fourth aspect of the present invention, the auxiliary operation member of the sorting and conveying unit is an operation rod supported on the sorting and conveying unit so as to be relatively movable along a moving direction of the sorting and conveying unit, The biasing means for biasing the operating rod into a state of projecting longer toward the introduction portion is provided.
Therefore, in the photosensitive material delivery device according to the fourth characteristic configuration of the present invention, an operation rod that protrudes long from the sorting and conveying unit toward the introducing portion according to the proximity of the sorting and conveying unit to the introducing portion is provided in the introducing portion. By acting on the operated member and switching it to the retracted position, the operating member can be switched to the retracted position before the sensitive material contacts the operating member. In addition, after the operation rod is switched to the retracted position, the operation rod is configured to be relatively movable in a contracting direction with respect to the sorting and conveying unit in accordance with further proximity to the introduction portion of the sorting and conveying unit. Therefore, the sorting / conveying unit can approach the introduction part sufficiently and reliably transfer the sensitive material to the introduction part while holding the operation member in the retracted position.

As shown in FIG. 2, the horizontal conveying device CH includes a roller pair 11 for conveying the photographic paper 2 drawn from the photographic paper magazine M, a cutter 12 for cutting the photographic paper 2 into a predetermined feed length, A chucker 13 that chucks the photographic paper 2 that has been cut into a rectangular predetermined size (including sizes such as L size and six size) by the cutter 12 and sends it horizontally. The exposure device Em receives a photographic paper 2 sent to the left of the paper surface by the chucker 13 of the horizontal conveying device CH, and scanning exposure by laser light with respect to the photographic paper 2 that the carry-in roller 15 further sends to the left of the paper surface. And a pair of exposure rollers 17 and 18 disposed on the upper transport side and lower transport side of the photographic paper 2 with reference to the light emitting portion 16a of the exposure engine 16. . Each of the exposure roller pairs 17 and 18 includes a fixed roller 17 that is rotationally driven at a constant speed by a stepping motor (not shown), a pressure-bonding posture that presses against the fixed roller 17, and a spacing posture that is separated from the fixed roller 17. And two pressure rollers 18 that can be individually switched between. In this exposure apparatus Em, the photographic paper 2 is pressure-bonded by at least one of the two pairs of exposure roller pairs 17 and 18 (upstream set or downstream set) and set in advance. The exposure processing mode is set such that exposure in the main scanning direction is performed by the exposure engine 16 at the same time that the sheet is conveyed in the sub scanning direction.

(Schematic configuration of the vertical transfer device CV)
As shown in FIG. 3, the vertical conveyance device CV (an example of the photosensitive material delivery device according to the present invention) receives the exposed photographic paper 2 sent out in a single row from the exposure device Em, and reverses the orientation of the photographic paper 2. The reversing unit 20 has a sorting transport unit 50 that receives the photographic paper 2 sent out in a single row from the reversing unit 20 and transports it to the introduction unit 60 of the development processing unit DE located on the downstream side (upper side). The sorting / conveying unit 50 has two rows in which the photographic papers 2 are arranged in the left-right direction (corresponding to the direction penetrating the paper surface of FIG. 3) intersecting the basic conveyance direction (the direction along the feed length of the photographic paper 2). It has a sorting function that sorts in a zigzag pattern (an example of multiple rows). The reversing unit 20 and the sorting and conveying unit 50 are supported by a generally rectangular holding plate 21 that extends vertically and horizontally.

(Configuration of reversing unit 20)
As shown in FIGS. 3, 4, and 5, the reversing unit 20 is supported by the reversing frame 22 that is supported by the holding plate 21 so as to be rotatable about a lateral axis X <b> 1 parallel to the width direction of the photographic paper 2. Have Specifically, the reversal frame 22 is supported by an output shaft 39 described later. As shown in FIG. 4, the reversal frame 22 includes a timing pulley P1 fixed to one side surface (left side as viewed from the exposure apparatus Em) of the reversal frame 22, a swing motor M1 including a stepping motor, and a timing pulley P1. And a timing belt B1 stretched between the motor and the output shaft of the swing motor M1. The reversal frame 22 is rotatably supported by a first pair of sandwiching rollers 23 and 24 that receive and sandwich the exposed photographic paper 2 supplied from the exposure apparatus Em. The first sandwiching roller pair 23, 24 includes a driving roller 23 that is rotationally driven around the axis X1 by a feed motor M3 that is a stepping motor, a timing belt B3, and the like, and a crimping posture and driving that are crimped to the driving roller 23. The driven roller 24 is provided so as to be switchable between an open posture separated from the roller 23.

  As shown in FIG. 6, the driven roller 24 is rotatably supported by a pressure-bonding frame 25 that can swing around an axis X2 parallel to the axis X1 with respect to the reversing frame 22. An operation shaft 26 that shares the shaft core with the shaft core X2 is fixed to the proximal end side of the crimping frame 25, and one end of the operation shaft 26 is left outward from the reversing frame 22 (also viewed from the exposure apparatus Em). An operating arm 27 extends from the protruding end of the operating shaft 26 at substantially the same angle as the crimping frame 25. An idle roller 28 is supported at the free end of the operation arm 27. The holding plate 21 is provided with a crimping cam 30 that is rotated around the axis X1 by a crimping motor M2 composed of a stepping motor, a timing belt B2, and the like, and the operating arm 27 is a coil spring 29 (FIG. 9). Therefore, the idle roller 28 is always urged so as to be pressed against the cam surface of the crimp cam 30. The shaft 24a of the driven roller 24 is supported in a long hole-like concave portion (extending in the vertical direction in FIG. 6) provided on the left and right sides of the pressure-bonding frame 25, and near both ends of the shaft 24a and the reversing frame 22. A compression coil spring 22 s is interposed between the holding plates 22 p protruding from both the left and right ends. The compression coil spring 22 s is provided through a spring insertion hole 25 b formed on each free end side of the left and right ends of the crimping frame 25. That is, the left and right end portions of the shaft 24a of the driven roller 24 can move independently in the left and right recesses in the long hole-like recess, and at the same time, the compression coil spring 22s below the holding plate 22p causes the driving roller 23 to move. This configuration allows the driven roller 23 and the operating shaft 26 to be driven or the driven roller 23 to be driven even if the shaft core and the crimping frame 25 are not strictly parallel. The pressing force acting between the roller 24 and the driving roller 23 is uniform along the axis of the roller.

  As shown in FIG. 9, the cam surface of the crimping cam 30 has a small-diameter surface 30a having the smallest radius, a medium-diameter surface 30b having a larger diameter than the small-diameter surface 30a, and a medium-diameter surface 30b along the circumferential direction. And a large-diameter surface 30c having a larger diameter. The small-diameter surface 30a and the medium-diameter surface 30b, and the medium-diameter surface 30b and the large-diameter surface 30c are adjacent to each other via a transition portion in which the curvature increases smoothly. Further, the small diameter surface 30a has an angle range of about 140 °, and the medium diameter surface 30b and the large diameter surface 30c both have an angle range of about 40 ° to 50 °. When the idle roller 28 is supported on the small diameter surface 30a according to the relative rotation angle of the crimp cam 30 with respect to the reversal frame 22, the driven roller 24 is moved to the drive roller 23 as shown in FIG. It is held in a “crimping posture” that is crimped to the surface. On the other hand, as shown in FIGS. 9 and 10A, when the idle roller 28 is supported by the medium diameter surface 30 b, the driven roller 24 is held in an “intermediate open posture” slightly separated from the drive roller 23. As shown in FIG. 10D, when the idle roller 28 is supported by the large diameter surface 30c, the driven roller 24 is held in a “fully open posture” that is further separated from the driving roller 23.

Further, based on the rotation control of the swing motor M1, the reversing frame 22 of the reversing unit 20 receives the exposed photographic paper 2 from the exposure device Em so that the first nipping roller pairs 23 and 24 are arranged vertically. In other words, in order to deliver the “receiving posture” in which the driven roller 24 is located directly above the driving roller 23 and the photographic paper 2 sandwiched between the first sandwiching roller pair 23, 24 to the sorting and conveying unit 50, The first delivery roller pair 23, 24 is arranged in the front-rear direction, in other words, a “delivery posture” that is located directly beside the drive roller 23 (the driven roller 24 is on the opposite side of the exposure device Em across the drive roller 23). Is switched by about 90 °. 10A and 10B show the “accepting posture” of the reversing frame 22, and FIGS. 10C and 10D show the “delivery posture” of the reversing frame 22.
A receiving guide plate for reliably and smoothly guiding the exposed photographic paper 2 fed from the exposure device Em between the first sandwiching roller pair 23 and 24 is provided at the front end side of the lower surface of the pressure-bonding frame 25. 25a is provided.

(Configuration of sorting and conveying unit 50)
As shown in FIGS. 4 and 5, the sorting and conveying unit 50 receives the photographic paper 2 from the exposure processing unit EX (more specifically, from the reversing unit 20) along the vertical surface of the holding plate 21. And a longitudinally moving member 31 (an example of a moving arm) supported so as to be able to reciprocate up and down between the received photographic paper 2 and a delivery position at which the received photographic paper 2 is delivered to one of the two left and right introduction parts 60 of the development processing unit DE. And a lateral movement member 32 (an example of a lateral movement member) supported on the longitudinal movement member 31 so as to be reciprocally movable left and right.
The longitudinally moving member 31 is linearly guided by a pair of cylindrical guide rods 33 extending vertically near the left and right end portions of the holding plate 21, while being closer to the center of the holding plate 21 than the guide rods 33. The pair of timing belts B4 extending up and down and a vertical movement motor M4 including a stepping motor that rotationally drives the left timing belt B4 via a timing pulley are vertically reciprocated. The left and right timing belts B4 are synchronously driven in the same direction by a connecting shaft 34 extending to the left and right in the vicinity of the upper end of the holding plate 21, and the longitudinally moving member 31 is in front of the left and right timing belts B4 (as viewed from the exposure apparatus Em). It is fixed to a part of the side. Thus, the longitudinally moving member 31 is not a cantilever structure that is supported from the left and right ends of the holding plate 21 toward the center, but the left and right ends are both supported by the left and right timing belts B4. Since the holding structure is provided, the lateral movement member 32 that is also supported by the vertical movement member 31 with the both-side support structure, and the photographic paper 2 held by the lateral movement member 32 are perpendicular to the surface of the photographic paper 2. It is transported up and down while maintaining a stable angular posture without inadvertent rocking around.

At the left end of the longitudinally moving member 31, a laterally moving motor M5 made of a stepping motor is disposed. ing. Therefore, the lateral movement member 32 is connected to a part of the timing belt B5 that is stretched between the lateral movement motor M5 and the timing pulley P2, so that the lateral movement motor M5 is driven based on forward and reverse rotation driving. To move left and right.
In this specification, for the sake of convenience, the right side of the center of the holding plate 21 is referred to as the right side or the right end, and the left side is referred to as the left side or the left end with the holding plate 21 viewed from the exposure apparatus Em side.
As shown in FIGS. 3 to 5, the laterally moving member 32 rotatably supports a second pair of sandwiching rollers 35 and 36 that press-clamp the photographic paper 2 fed upward from the reversing unit 20. The second sandwiching roller pair 35 and 36 is rotationally driven (via a rotation transmission mechanism 38 described later) by the driving force of the feed motor M3 of the reversing unit 20 when the sorting and conveying unit 50 is connected to the reversing unit 20. It comprises a drive roller 35 and a driven roller 36 supported in a state where it is pressed against the drive roller 35. The drive roller 35 is configured to rotate integrally with a connecting shaft 37 extending toward the right end of the longitudinally moving member 31.
Further, two operation rods 51 projecting upward are provided near the left and right central portions of the vertically moving member 31 of the sorting and conveying unit 50. The function of the operation rod 51 will be described later.
Further, in the laterally moving member 32 of the sorting and conveying unit 50, a portion sent out above the second sandwiching roller pair 35 and 36 of the photographic paper 2 sandwiched by the second sandwiching roller pair 35 and 36 is held by the holding plate 21. Two support plates 32a capable of supporting the same part from both the front and back surfaces are provided so as not to fall down to the side or the opposite side of the holding plate 21. Further, a pair of thin protrusions projecting upward are provided on the support plate 32a. An auxiliary protrusion 32b is included.

(Configuration of the rotation transmission mechanism 38)
A rotation transmission mechanism 38 for transmitting the driving force of the feed motor M3 of the reversing unit 20 to the connecting shaft 37 is provided between the reversing unit 20 and the sorting and conveying unit 50. The rotation transmission mechanism 38 includes an output unit 38 a provided near the right end of the reversing unit 20 and an input unit 38 b provided near the right end of the vertically moving member 31 of the sorting and conveying unit 50. The output unit 38a and the input unit 38b are configured such that the vertical moving member 31 of the sorting and conveying unit 50 is positioned at the receiving position, and the left and right centers of the second sandwiching roller pair 35 and 36 of the horizontal moving member 32 are reversed units. The feed motors of the reversing unit 20 are connected to each other only when they coincide with the left and right centers of the first pair of first clamping rollers 23 and 24 (this state is defined as the lateral movement member 32 being located at the home position). The driving force of M3 can be transmitted to the connecting shaft 37.
As shown in FIGS. 5 and 8, the output portion 38a of the transmission mechanism 38 includes an output gear G1 fixed to an output shaft 39 that rotates integrally with the drive roller 23 of the reversing unit 20, and a first meshed with the output gear G1. The first intermediate gear G2 is supported on the free end side of the positioning bracket 40 that is swingably supported on the output shaft 39. The positioning bracket 40 is biased by a coil spring 41 so that the cam portion 40a at the upper end of the positioning bracket 40 is displaced toward the exposure apparatus Em side.
On the other hand, the input portion 38b of the transmission mechanism 38 has an input gear G4 fixed to the connecting shaft 37 and a second intermediate gear G3 meshed with the input gear G4. A contact sleeve 42 is disposed at the base end of the second intermediate gear G3.

As shown by the downward arrow in FIG. 8A, when the sorting and conveying unit 50 is lowered toward the reversing unit 20 with the lateral movement member 32 positioned at the home position, first, the contact sleeve 42 is The positioning bracket 40 comes into contact with the cam portion 40a, and further descends while swinging the positioning bracket 40 against the biasing force of the coil spring 41 based on the pressing action of the contact sleeve 42 against the cam portion 40a. Thus, with the impact collision between the sorting and conveying unit 50 and the reversing unit 20 being alleviated by the urging force of the coil spring 41, as shown in FIG. The meshing state with the second intermediate gear G3 is achieved. Further, when this meshing state is obtained, the first intermediate gear G2 and the second intermediate gear G2 are connected to the second intermediate gear G2 and the second intermediate gear G3 so that the front ends of the teeth do not collide with each other. The intermediate gear G3 is displaced in the left-right direction in FIG.
While the above meshing state is maintained, the driving force of the feed motor M3 of the reversing unit 20 is such that the driving roller 23 of the reversing unit 20, the output shaft 39, the output gear G1, the first intermediate gear G2, and the second intermediate gear. G3, the input gear G4, and the connecting shaft 37 are transmitted in this order, and are transmitted to the driving roller 35 that rotates integrally with the connecting shaft 37. As a result, the drive roller 23 of the reversing unit 20 and the drive roller 35 of the sorting and conveying unit 50 rotate synchronously in the same direction.

(Configuration of introduction unit 60)
As shown in FIG. 7, the introduction units 60 of the development processing unit DE are provided side by side in two places on the left and right. Each introduction unit 60 is sandwiched between a pair of introduction rollers 61 a and 61 b that are always pressed against each other to sandwich the photographic paper 2 delivered from the sorting and conveying unit 50 and a pair of introduction rollers 61 a and 61 b for the photographic paper 2. It is composed of an introduction assembly 70 including a correction mechanism 63 for correcting a portion located upstream (in fact, the lower side) of the portion being curved into a curved shape.
The introduction assembly 70 includes an introduction frame 71 that rotatably supports the introduction roller pair 61a and 61b. On the lower surface side of the introduction frame 71, the leading end of the photographic paper 2 is guided between the introduction roller pair 61a and 61b. Therefore, a guide surface 71a having a smooth curved surface is integrally formed.

  The correction mechanism 63 switches the posture of the swing arm 64 and an swing arm 64 (an example of an operation member) that is swingably supported around a horizontal axis X3 provided at a predetermined position of the introduction frame 71. And a switching mechanism to be described later. The swing arm 64 has a generally L-shaped side surface as a whole, and a first arm portion linearly extending from the first end portion 64a where the swing axis X3 is disposed to the first free end 64b. 64F, and a second arm portion 64G extending linearly from the first free end 64b to a second free end 64c located in a different direction from the first arm portion 64F. The second free end 64c is located further radially outward than the first free end 64b with respect to the swing axis X3. At the first free end 64b, a lightweight roller 65 made of synthetic resin or the like is free to rotate around an axis parallel to the width direction of the photographic paper 2 as an action portion that bends the photographic paper 2 through contact. It is pivotally supported by. In addition, a pair of operated rods 66 (an example of an operated portion) extend sideways from the left and right side surfaces of the second free end 64c. The swing arm 64 is swung by receiving an action from an operation rod 51 (an example of an auxiliary operation member and a switching mechanism) provided in the sorting and conveying unit 50 via an operated rod 66.

As illustrated in FIG. 12C and the like, as a result of the swing around the axis X3, the swing arm 64 moves the roller 65 along the movement path of the photographic paper 2 sent to the introduction unit 60 by the sorting transport unit 50. As illustrated in FIG. 12A and the like, the roller 65 can be displaced between the “operation position” where a part has entered and the “retraction position” where the roller 65 is retracted from the movement path. The swing arm 64 is normally biased to the “operation position” by a biasing means such as a torsion coil spring 68 (an example of a biasing mechanism and a switching mechanism). Is moved to the “retracted position” against the urging force of the urging means by the action from the operation rod 51 when the urging means is in proximity.
As shown in FIGS. 11 and 12, the operating rod 51 is slidably supported relative to the longitudinally moving member 31 of the sorting / conveying unit 50 along the moving direction of the sorting / conveying unit, that is, up and down. It comprises a part 51a and an operating piece 51b provided at the upper end of the sliding part 51a, and a coil spring 52 (an example of an urging means) is externally fitted to the sliding part 51a. Since the coil spring 52 is interposed between a part of the longitudinally moving member 31 and the lower end portion of the operation piece 51b, the coil spring 52 is usually pressed by the biasing force of the coil spring 52 to be expanded. When the sorting / conveying unit 50 is located in the vicinity of the lower receiving position, the operation rod 51 is urged so as to protrude longer toward the upper introducing portion 60. The biasing force of the coil spring 52 can be switched to the “retracted position” against the biasing force of the coil spring 68 by twisting the swing arm 64 in accordance with the movement of the sorting and conveying unit 50 close to the introduction portion 60. It is set large enough.
Further, as shown by a one-dot chain line in FIG. 4, the interval between the operation pieces 51b of the pair of operation rods 51 is determined when the photographic paper 2 having a small width of L size or less is transferred to one of the left and right introduction parts 60 The photographic paper 2 alternately delivered to the introduction section 60 flows through the development processing section DE in two rows in a staggered manner), and the two operating rods 51 are connected to the pair of left and right swing arms 64. When the bar to be operated 66 can be pushed up evenly and a large size photographic paper such as a six-piece cut across both the left and right introduction parts 60 is delivered to the vicinity of the centers of the two right and left introduction parts 60 (in this case, photographic paper Are flown in a single line through the center of the development processing unit DE without being divided into left and right), as shown by the positions of the pair of operation rods 51 indicated by solid lines in FIG. Of the swing arm 64 of the left-hand introduction part 60 It is set to the) two oscillating arms 64 by pushing up and the operating rod 66 of the left swing arm 64 side to be operating rod 66 and the right inlet unit 60 can be operated simultaneously.

(Control form for vertical conveyor CV)
The vertical transfer device CV is controlled as follows as an example.
<1-1> First, when the exposed photographic paper 2 is supplied from the exposure apparatus Em, the sorting / conveying unit 50 is preliminarily provided at a delivery position (close to either the left or right introduction part 60 of the development processing unit DE). 10 (a), the reversing frame 22 of the reversing unit 20 has a "receiving posture" in which the first nipping roller pairs 23 and 24 are arranged vertically, and The driven roller 24 of the first clamping roller pair 23, 24 is held in an “intermediate open posture” that is slightly separated from the drive roller 23. That is, the idle roller 28 is supported by the medium diameter surface 30 b of the crimping cam 30. In this state, the tip of the exposed photographic paper 2 supplied from the exposure apparatus Em is sent between the first nipping roller pair 23 and 24. In this “intermediate opening posture”, the photographic paper 2 supplied from the exposure device Em is smoothly fed between the first sandwiching roller pair 23 and 24 without fluttering between the driving roller 23 and the driven roller 24. Thus, the opening dimension between the rollers is set. The photographic paper 2 is sent from the exposure device Em in a substantially horizontal posture with the emulsion surface facing upward.

  <1-2> Next, while the rear end of the photographic paper 2 has been exposed by the exposure engine 16 of the exposure apparatus Em and is still being sandwiched between the pair of exposure rollers 17 and 18 on the downstream side, FIG. ), While the reversing unit 20 is kept in the “accepting posture”, the drive roller 23 of the first clamping roller pair 23, 24 starts to rotate at the same peripheral speed as the exposure roller pair 17, 18 on the downstream side. Subsequently, the driven roller 24 is switched to the “crimping posture”. Switching to the “crimping posture” of the driven roller 24 is realized by rotating the crimping cam 30 by about 240 ° counterclockwise (as viewed from the left end of the holding plate 21) by the rotational driving of the crimping motor M2. The idle roller 28 is supported on the small diameter surface 30a of the crimp cam 30 (however, the position closest to the large diameter surface 30c among the small diameter surfaces 30a).

<1-3> The rear end of the photographic paper 2 comes out of the downstream exposure roller pair 17, 18 and is transported only by the first clamping roller pair 23, 24 of the reversing unit 20. When the protruding amount of the 25 from the receiving guide plate 25a reaches a predetermined value, the rotation of the driving roller 23 is stopped, and then the driven roller 24 is brought into the “crimping posture” as shown in FIG. While maintaining, the reversal frame 22 is switched to the “delivery posture” in which the first nipping roller pair 23 and 24 are arranged in the front and rear. By this switching operation, the photographic paper 2 sandwiched between the first sandwiching roller pair 23 and 24 is in a substantially vertical posture with the emulsion surface facing the direction of the development processing unit DE. The switching operation to the “delivery posture” can be realized only by rotating the reversing frame 22 by 90 ° in the counterclockwise direction (as viewed from the left end of the holding plate 21) by the swing motor M1 while the crimping cam 30 is stopped. . This is because, based on the rotation of the reversal frame 22, the idle roller 28 also moves on the circumferential surface of the crimping cam 30, but the reversal frame 22 is rotated 90 ° as understood from FIG. However, the idle roller 28 is still maintained within the range of the small diameter surface 30a of the crimp cam 30 (because the small diameter surface 30a has an angle range of about 140 °). Therefore, with this cam surface configuration of the crimping cam 30, the operation of switching the reversing frame 22 to the “delivery posture” while the driven roller 24 is maintained in the “crimping posture” can be performed while the crimping cam 30 is stopped.
The operation of setting the protrusion amount of the rear end of the photographic paper 2 from the receiving guide plate 25a to the predetermined value is a detection signal of the front end of the photographic paper 2 by a non-contact sensor provided in the vicinity of the receiving guide plate 25a. The projection amount can be controlled based on the data used when the photographic paper 2 is exposed by the exposure device Em.

  <1-4> Almost at the same time when the reversing frame 22 is switched to the “delivery posture”, the sorting and conveying unit 50 is lowered by the vertical movement motor M4 as shown in the middle of FIG. 20 (an example of a receiving position). When the lateral movement member 32 is displaced to one of the left and right at the delivery position of the sorting and conveying unit 50, the lowering operation of the sorting and conveying unit 50 causes the laterally moving member 32 to move with respect to the holding plate 21 by the laterally moving motor M5. It is performed while centering. When the meshing state between the first intermediate gear G2 of the reversing unit 20 and the second intermediate gear G3 of the sorting and conveying unit 50 is achieved based on this proximity, the feed motor M3 is continuously driven to rotate. Then, the driving roller 23 of the reversing unit 20 and the driving roller 35 of the sorting / conveying unit 50 rotate synchronously in the same direction, and the photographic printing paper 2 starts to move upward from the reversing unit 20 toward the sorting / conveying unit 50.

  <1-5> Based on the synchronous rotation of the driving roller 23 of the reversing unit 20 and the driving roller 35 of the sorting and conveying unit 50, the upper end of the photographic paper 2 is nipped by the second sandwiching roller pair 35 and 36 of the sorting and conveying unit 50. When the upper end of the photographic paper 2 protrudes upward from the sorting and conveying unit 50 by a predetermined length, the rotation driving of the feed motor M3 is stopped, and subsequently, as shown in FIG. The photographic paper 2 is delivered from the reversing unit 20 to the sorting and conveying unit 50 by switching the 20 driven rollers 24 to the “fully open posture”. The switching to the “fully open posture” is realized by rotating the crimping cam 30 by about 240 ° clockwise (as viewed from the left end of the holding plate 21) by the rotational driving of the crimping motor M2, thereby rotating the rolling roller. 28 is supported by the large-diameter surface 30 c of the crimping cam 30.

  <1-6> As soon as the driven roller 24 of the reversing unit 20 is switched to the “fully open posture”, the ascending operation of the sorting and conveying unit 50 is started. When the photographic paper 2 has a small width such as an L plate, the development processing unit DE can perform parallel conveyance in two rows on the left and right sides. As shown by the oblique arrows in FIG. While the lateral movement member 32 is shifted to one of the left and right (left side in the figure), the second movement roller 32 of the lateral movement member 32 is moved up to a position close to the introduction unit 60 of the development processing unit DE (an example of a delivery position). The photographic paper 2 sandwiched between the pairs 35 and 36 is transferred to a sandwiching roller pair roller 61 of the left introduction portion 60. That is, in this case, the photographic paper 2 is pulled out from the first sandwiching roller pair 23, 24 of the reversing unit 20 by the sorting and conveying unit 50 at a relatively high speed in a diagonal direction in the upper left, not directly upward. Since 24 is switched to the “fully open posture”, a situation in which the photographic paper 2 is damaged by friction with the first clamping roller pair 23 and 24 is avoided.

  <1-7> In the initial state in the process in which the sorting and conveying unit 50 approaches the introducing roller pair 61 (for example, on the left introducing portion 60), the swing member 64 is a torsion coil spring 68 as shown in FIG. It is in the “operation position” by the urging force. When the sorting and conveying unit 50 further approaches the introduction roller pair 61 from this state, first, two operations are performed before the leading edge of the photographic paper 2 comes into contact with the roller 65 of the swinging member 64 at the “operation position”. When each operation piece 51b of the rod 51 comes into contact with the pair of operated rods 66 of the swing arm 64 of the left introduction portion 60 and the sorting and conveying unit 50 further approaches the introduction roller pair 61, FIG. As shown, the operated rod 66 starts to be pushed up, and the swing member 64 is switched to the “retracted position”. Accordingly, the leading edge of the photographic paper 2 sandwiched between the sorting and conveying unit 50 comes out into the space above the roller 65 without contacting the roller 65 of the swinging member 64. When the sorting / conveying unit 50 continues closer to the introduction roller pair 61, the operation piece 51b of the operation rod 51 starts to contact a part of the introduction frame 71 as shown in FIG. A state in which the swinging member 64 is held in the “retracted position” because the sliding movement (which can be expressed as contraction) is started with respect to the longitudinally moving member 31 against the urging force of the coil spring 52. Thus, the sorting / conveying unit 50 can continue to rise, and finally, as shown in FIG. 12B, the auxiliary protrusions 32b of the sorting / conveying unit 50 are arranged between the plurality of roller portions 80a of the introduction roller pair 61. At the position where it has risen until it enters the gap 80b formed between them (the coil spring 52 of the operating rod 51 is almost completely contracted), the leading edge of the photographic paper 2 is developed. Is delivered to the introduction roller pair 61 is always rotated at the conveying speed synchronized with the feed speed of the photographic paper 2 in the section DE.

The photographic paper 2 delivered to the introduction roller pair 61 is started to be conveyed toward the development processing unit DE by the introduction roller pair 61, and subsequently subjected to development processing through each development processing tank.
Since the drive roller 35 of the sorting / conveying unit 50 is separated from the reversing unit 20 and thereafter enters the idle state without carrying force, the photographic paper 2 is held by the second weight with its own weight while the sorting / conveying unit 50 is raised. A ratchet mechanism for preventing the drive roller 35 from being reversed is provided so as not to fall off the roller pair 35, 36. As shown in FIG. 8, the ratchet mechanism includes a ratchet wheel 43 integrally formed on the side surface of the input gear G <b> 4, a locking posture in which the tip meshes with the pinion wheel 43, and a release posture that has come out of the tooth wheel 43. The claw member 44 is supported on the lateral movement member 32 so as to be able to swing between the coil member 45 and a coil spring 45 that urges the claw member 44 to a locking posture. The direction of the claw of the claw member 44 prevents the reversal of the driving roller 35, and at the same time, the introduction roller pair 61 prints from the second clamping roller pair 35, 36 which is a pressure-bonding type roller pair that is always kept in a pressure-bonded state. It is set to allow the operation of extracting the paper 2 upward.

<1-8> When extraction of the photographic paper 2 from the second nipping roller pair 35, 36 by the introduction roller pair 61 is completed, as shown in FIG. At this time, the lateral movement member 32 also starts moving toward the center home position. When the sorting / conveying unit 50 starts to move downward, first, the operation rod 51 starts to expand due to the urging force of the coil spring 52, and the sorting / conveying unit 50 moves further downward to extend the operating rod 51 to the maximum length. Then, as indicated by the arc-shaped arrow in FIG. 12C, the swing arm 64 starts to return toward the “operation position” by the biasing force of the torsion coil spring 68. In this returning process, the roller 65 of the swing arm 64 pushes the emulsion surface side of the lower part of the photographic paper 2 still protruding below the introduction roller pair 61 in the direction opposite to the holding plate 21, The paper 2 is corrected so as to be curved in a substantially arc shape (the curved shape in which the emulsion surface side is convex is generally not accompanied by damage such as folding of the photographic paper). In this correction, the lower end portion of the preceding photographic paper 2 started to be fed (introduced) toward the development processing unit DE by the introduction roller pair 61 (for example, on the left side) This is performed in order to prevent interference and damage to the longitudinally moving member 31 of the sorting and conveying unit 50 which is to be received and delivered to the introduction unit 60 (on the right side). As a result, the trailing edge of the preceding photographic paper 2 is The subsequent photographic paper 2 can be transferred to the other introduction unit 60 without waiting for the timing of passing through the introduction unit 60, and the processing speed can be increased accordingly.
Since the roller 65 is pivotally supported around an axis parallel to the width direction of the photographic paper 2, the roller 65 is also supported when extruding a part of the photographic paper 2 to the side opposite to the holding plate 21. Even when the extruded portion of the photographic paper 2 is pulled upward, the surface of the photographic paper 2 is not easily damaged because it easily rolls on the basis of the contact with the surface of the photographic paper 2. Further, the point that the roller 65 is made of a small member made of a lightweight material such as a synthetic resin also promotes the tendency to roll very easily based on the contact with the surface of the photographic paper 2. The surface of the paper 2 is hardly damaged.

<1-9> As soon as the photographic paper 2 sandwiched between the sorting and conveying unit 50 is pulled out from the first sandwiching roller pair 23 and 24 of the reversing unit 20, the drive roller 23 and the sorting and conveying unit 50 linked thereto are immediately The rotation drive with the driving roller 35 is stopped, and the reversing frame 22 of the reversing unit 20 is again in the “receiving posture” in which the first pair of nipping rollers 23 and 24 are arranged vertically as shown in FIG. At the same time, the driven roller 24 of the reversing unit 20 is switched to the “intermediate opening posture”. As a result, a posture for receiving the next exposed photographic paper 2 supplied from the exposure apparatus Em is obtained. This <1-9> step is started substantially simultaneously with the downward movement of the sorting and conveying unit 50 in the above <1-8> step.
The operation of switching the reversing frame 22 of the reversing unit 20 from the “delivery posture” to the “receiving posture” and simultaneously switching the driven roller 24 of the reversing unit 20 from the “fully opened posture” to the “intermediate opened posture” This can be realized simply by rotating the reversal frame 22 by 90 ° clockwise (as viewed from the left end of the holding plate 21) by the swing motor M1 while stopped. That is, when the reversing frame 22 is rotated 90 ° counterclockwise while the crimping cam 30 is stopped, the free-rolling roller 28 of the reversing unit 20 rolls on the crimping cam 30 and moves from the large diameter surface 30c. Since it moves to the radial surface 30b, the driven roller 24 is switched from the “fully open posture” to the “intermediate open posture”. Therefore, the cam surface configuration of the crimping cam 30 switches the reversal frame 22 of the reversing unit 20 from the “delivery posture” to the “accepting posture”, and at the same time the driven roller 24 of the reversing unit 20 from the “fully open posture” to the “intermediate posture”. The operation of switching to the “open posture” can be performed while the crimping cam 30 is stopped.
The next photographic paper 2 supplied from the exposure apparatus Em is handed to the sorting and conveying unit 50 in the same manner as the previous photographic paper 2, and the sorting and conveying unit 50 now feeds the photographic paper to the right introduction unit 60. To the introduction roller pair 61 (when the photographic paper 2 is a small size such as an L plate).

  Thereafter, similar control is repeated. However, in the case of processing a large photographic paper such as a six-cut size that cannot be conveyed in parallel in a plurality of rows in the development processing unit DE, the sorting and conveying unit 50 includes the first sandwiching roller pair 23 of the reversing unit 20, The photographic paper 2 received from 24 is conveyed directly upward (with no or almost no lateral movement member 32 moved from the home position), and the center of the photographic paper 2 in the width direction is the center of the pair of left and right introduction rollers 61. Hand over like so.

[Another embodiment]
The operation member for bending the photographic paper 2 is not configured to be switched by the auxiliary operation member provided in the sorting and conveying unit 50, but the position or posture of the operating member according to the proximity of the sorting and conveying unit 50 to the introduction unit 60 The photographic paper 2 may be curved by switching the operation with an actuator such as an electric motor. Alternatively, the photographic paper 2 may be curved without causing the action portion to contact the photographic paper 2 by blowing air laterally onto the surface of the photographic paper 2 from a nozzle provided in a part of the introduction assembly 70 or the like. .
