Abstract

PURPOSE:To surely deliver a photosensitive material from a roller pair to an absorbing board unit by moving the absorbing board unit which attracts the photosensitive material carried to a prescribed position by means of the roller pair along a stool section at a speed which is lower than the carrying speed of the roller pair. CONSTITUTION:A moving member 202 constituting part of a photosensitive material carrying section 200 is provided on the extension line of the carrying direction of a photosensitive material 14 which is carried by a roller pair 104 under the guidance of a guide plate 120. The material 14 is attracted to the absorbing board 264 of the section 200 and carried to a photosensitive material delivering section after the material 14 is exposed on a stool 302. Since the moving speed of the member 202 is made slower than the carrying speed of the roller pair 104 so that the material 14 does not become tense, the material 14 never falls down from the absorbing board unit. Therefore, the need of a complicated mechanism can be eliminated and the material 14 surely be delivered from the roller pair 104 to the absorbing board unit 254 without making any complicated control.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an apparatus for making an inspection plate, and more specifically, for making an inspection plate (used for checking the quality of color printed matter) using a photosensitive material. Concerning a plate inspection production device.

[Conventional technology]

When using a printing machine to print a large amount of color printing, for example, color advertisements (so-called insert advertisements) attached to newspapers, etc., use a plate inspection device (color proof production device) before printing with the printing press. I try to check it before actually printing.

The plate inspection device includes a surface plate section where the photosensitive material and the developed original film after decomposition exposure are conveyed and positioned, and an exposure section which is arranged correspondingly on the surface plate section and exposes the image of the document film onto the photosensitive material. a processor section that develops the exposed photosensitive material; and a transfer section that transfers the photosensitive material from the surface plate section to the processor section. A plurality of original films are prepared for each color separation component, and one set consists of a plurality of original films. are exposed sequentially. The exposed photosensitive material is transported from the surface plate section to the processor section via the delivery section, where it is developed,
Bleach-fixed, washed and dried. This processed photosensitive material allows for a pre-check before actual printing. As a result, if there is a problem with the color, image position, character error, etc. of the photosensitive material, for example, corrections can be made to the original film before printing in large quantities using a printing machine.

By the way, when positioning the photosensitive material on the surface plate in the plate inspection device, the photosensitive material pulled out from the magazine is conveyed while being held by a pair of rollers, and its leading end is sucked by a suction cup.

This suction cup is installed on a movable member that moves on the surface plate, and the photosensitive material is conveyed by a pair of rollers, and by moving the movable member with the photosensitive material being sucked by the suction cup, the photosensitive material is moved onto the surface plate. L).

[Problem to be solved by the invention]

However, the photosensitive material is pinched and conveyed by a pair of rollers, pulled out from a magazine, and then sucked by a suction cup, and this suction cup is moved on a surface plate by a moving member. For this reason, if it is attempted to use the same drive system for the roller pair and the moving member, a complicated mechanism will be required. Therefore, if the drive systems are separated, a speed difference will occur between the conveying speed of the roller pair and the moving speed of the moving member. If the moving speed of the moving member is faster than the conveyance speed of the roller pair, the photosensitive material may become tense and detach from the suction cup, and if the moving speed of the moving member is slower than the conveyance speed of the roller pair, the roller pair may The photosensitive material between it and the suction cup will bend. For this reason, the moving speed of the moving member and the conveying speed by the roller pair are synchronized,
If an attempt is made to match them, it is necessary to install an encoder or the like for each to detect and control the driving state, which makes the control system complicated.

The present invention takes the above facts into consideration, does not require a complicated mechanism,
Another object of the present invention is to provide a plate inspection device that can reliably transfer photosensitive material between a pair of rollers and a suction cup unit without performing complicated controls.

In addition to the above purpose, a loop of photosensitive material is formed between the roller pair and the suction cup unit to prevent the photosensitive material from falling off the suction cup unit, and the gap between the guide plates is adjusted by following the behavior of the loop of photosensitive material. The purpose of the present invention is to obtain a plate inspection device that can expand or contract dimensions and prevent clogging of photosensitive materials.

The large lid 24 is attached via a hinge 26.

Therefore, the large lid 24 is opened by rotating it clockwise in FIG. 1 about the hinge 26.

Further, the second large lid 24 is provided with a rectangular hole 702, and a small lid 704 is attached thereto via a hinge 714 (see FIG. 27). The hinge 714 is attached to the edge of the rectangular hole 702 on the back side in FIG.
It is configured to be opened by rotating it from the front side in Figure 2 of Figure 0 toward the back side. This small lid 704 is opened when loading the original film 16 into the film loading section 700. A locking mechanism 705 is attached to the periphery of the rectangular hole 702, so that the small lid 704 can be locked in a closed state.

The film loading section 700 is provided with a frame-shaped support base 7 - 8 to which an overlay 708 (see FIG. 28) on which the document film 16 is placed is attached, and is connected to the surface plate section 300 . It is possible to move back and forth between the two. That is, the film loading section 700 and the exposure section 400 are communicated through a rectangular hole 726. This rectangular hole 726

■Magazine loading section 1. OO As shown in FIG. 4, a rectangular hole is provided on the left side of the inspection plate making device @10, and serves as a loading opening 106 for the magazine 102. The magazine 102 is box-shaped and has a drawer opening 108 on its two sides for drawing out the photosensitive material 14 housed in a roll. Although the outlet 108 communicates with the inside of the magazine 102, it is structured to prevent light from entering.

A light reflecting sheet 110 is attached to the wall surface of the magazine 10.2 facing the loading port 106.

A maximum of four light reflecting sheets 110 can be attached, and the presence or absence of each light reflecting sheet is determined depending on the type and size of the photosensitive material 14 to be accommodated. In this example, there are three types of photosensitive materials to be applied: positive paper, negative paper, or positive film, and three types of width sizes of the photosensitive materials (383=9
type), these are distinguished by the light reflection sheet) 110. That is, the nine types of photosensitive materials 14 are distinguished by the presence or absence of the four light-reflecting sheets 110.

Four rectangular holes 112 are provided in the back wall surface 106A of the loading port 106 in correspondence with the light reflecting sheet 110.

On the back side of the wall surface 106A in which the rectangular holes 112 are provided, photoelectric sensors 114 are arranged corresponding to each of the rectangular holes 112. The photoelectric sensor 114 has its signal line connected to the control device 800. In addition, the photoelectric sensor 11
4 passes through the rectangular hole 112 and is reflected by the light reflecting channel 110, and the photoelectric sensor 114 detects the light again.

Therefore, the presence or absence of the light reflecting sheet 110 can be replaced with an electrical signal and supplied to the control device 800.

By loading the magazine 102 into the loading port 106, the loading port 106 is shielded, and light is prevented from entering the plate inspection apparatus 10-1 from the loading port 106.

A guide plate (not shown) is provided above the outlet 108 of the magazine 102 loaded into the loading port 106, and the photosensitive material 14 guided by this guide plate is transferred to the pair of rollers 10.
4.

One of the twenty roller pairs 104 is connected to the drive shaft of a motor (not shown). The motor is connected to a control device 800, and conveyance of the photosensitive material 14 is controlled by the control device 800.

A cutter 116 is disposed on the conveyance path of the photosensitive material 14 whose direction has been changed by 90 degrees by the roller pair 104.

Cutter 116 is connected to control device 800. The cutter 116 is activated by a signal outputted from the control device 800 when the photosensitive material 14 has been conveyed by a predetermined amount, and cuts the photosensitive material 14.

As shown in FIG. 4A and FIG. 5(A), the cutter 11
A guide plate 120 is disposed downstream of 6. The guide plate 120 is composed of an upper guide plate 122 with a short dimension facing the front surface of the photosensitive material 14 and a lower guide plate 124 with a long dimension corresponding to the back surface of the photosensitive material 14 .

The lower guide plate 124 is fixed to a base plate 270 which is the initial position of a suction cup unit 254, which will be described later, and the end on the cutter 116 side is bent diagonally downward in a direction away from the photosensitive material 14. .

Further, the opposite end of the lower guide plate 124 is bent at a substantially right angle in a direction away from the photosensitive material 14 . Brackets 12 are provided at both ends of the lower guide plate 124 in the width direction.
6 is fixed with a bolt 128. The bracket 126 has an end portion on the inner side (photosensitive material 14 side) of the mounting surface of the bolt 128 bent at a substantially right angle to form an upright portion 130 . Circular holes 132 coaxial with each other are formed in this standing portion 130, and shafts 134 are respectively supported via bushes 136.

The shaft 134 is inserted into a cylindrical member 138 attached to both ends of the upper guide plate 1220 in the width direction.

The cylindrical member 138 is fixed by a bent portion 140 and a helix 142 bent at a substantially right angle in a direction away from the photosensitive material 14 at the downstream end of the upper guide plate 122 .

This allows the upper guide plate 122 to rotate about the shaft 134 in the direction of arrow R in FIGS. 4A and 5. Furthermore, dampers 144 made of rubber and having a rectangular block shape are attached to both ends of the lower guide plate 124 in the width direction. Therefore, the upper guide plate 122 is normally held in contact with the damper 144 due to its own weight, and in this state, the upper guide plate 122 and the lower guide plate 124 are parallel, and the gap size between them is constant. (approximately 3 mm).

Therefore, the leading end of the photosensitive material 14 transported by the pair of rollers 104 is inserted between the upper guide plate 122 and the lower guide plate 124, and is guided by the guide plate 120 to form a surface plate, which will be described later. 300.

Here, if a slack (loop) is formed in the photosensitive material 14 in the thickness direction (see the imaginary line in FIG. 5(A)), the upper guide plate 122 follows the behavior of this loop and moves the shaft 134. The upstream portion of the upper guide plate 122 is separated from the lower guide plate 124 by rotating in the direction of the arrow R in FIGS. 4A and 5(A) about the center, thereby preventing the loop from being crushed. .

That is, the upper guide plate 122 is pushed up by the stiffness of the photosensitive material 14.

■Photosensitive material conveyance section 200 As shown in FIGS. A moving member 202 that constitutes a part of 200 is provided. The photosensitive material 14 is further transported by the moving member 202 to a predetermined position.

A pair of rails 210 extending parallel to the conveying direction of the photosensitive material 14 are sandwiched between the rollers 208 and one roller 208 supported by the lower shaft 206.
As a result, the moving member 202 moves to the two sets of rollers 208.
It is supported by the rail 210 by and is configured to be slidable along the rail 210.

Furthermore, both ends of the moving member 202 in the longitudinal direction are engaged with a part of a chain 214 disposed along the rail 210 via brackets 212 . chain 214
The rail 210 is looped around a pair of sprockets 216 disposed near both longitudinal ends of the rail 210. One sprocket 216 is connected to a rotating shaft 218A of a motor 218 via a connecting means 217.

Motor 218 is connected to controller 800.

When the motor 218 is driven, the sprocket 216 is rotated by this driving force, and the chain 214 is driven by the rotation of the sprocket 2160, and the moving member 202 is accordingly moved along the rail 210. .

Note that the moving member 202 can be moved back and forth along the rail 210 by rotation of a motor 218 in forward and reverse directions. Photoelectric sensors 220 are provided near both ends of the rail 210 in the longitudinal direction, and signal lines of the photoelectric sensors 220 are connected to the control device 800, respectively. The light emitting part and the light receiving part of the photoelectric sensor 2200 are connected to the moving member 202.

26, and the output shaft 226.26 of this gearbox 226. A is rotated at a reduced speed relative to the rotation of the rotation shaft 224A of the motor 224. A circular cam 228 is attached to the output shaft 226A, and a connecting shaft 230 is attached to the end surface of the cam 228 at a position offset from the axis.
is installed. The second connecting shaft 230 is connected to the moving member 2
It is inserted into a bearing 234 provided on a support plate 232 that is disposed at the bottom of FIG. 6 of 02 and parallel to the moving member 202. The outer periphery of the bearing 234 is fixed by two brackets 236A and 236B attached to the upper surface of the support plate 232. Therefore, the bearing 234 is moved together with the support plate 232.

Here, when the motor 224 is driven, the gear box 2
26 output shaft 226A is decelerated and rotates, and the connecting shaft 23
0 rotates around the axis of cam 228. With one rotation, the bearing 234 is reciprocated in the direction toward and away from the moving member 202, that is, in the vertical direction in FIG. 6.

As shown in FIG. 8, a fixed base 238 is attached inside the pair of leg plates 204 of the movable member 202 at a position equidistant from each leg plate 204. As shown in FIG. The fixed base 238 is formed in a cylindrical shape with a circular hole 240 provided in the axial center, and a flange portion 238A that projects in the radial direction is formed at the end on the movable member 202 side. A plurality of circular holes 238B are provided in this flange portion 238A with equal dimensions around the axis, and correspondingly, a female thread 202A is formed in the moving member 202. Here, the bolt 242 is passed through the circular hole 238B, and the female screw 202 is inserted into the circular hole 238B.
By screwing into A, the fixed base 238 is fixed to the movable member 202.

One end of a shaft rod 244 is inserted into the circular hole 240 of the fixed base 238, and is fixed by a screw 246 screwed into a female threaded hole 238C penetrated from the outer periphery of the fixed base 238 to the circular hole 240.

The other end of the shaft rod 244 is pivotally supported by a cylindrical sliding base 248 provided on the support plate 232.

The sliding base 248 is provided in the support plate 232 through the oval hole 2.
It is inserted into 32A. A radial flange portion 248A is formed at the axially intermediate portion of the sliding base 248. This flange portion 248A is in contact with the lower end surface of the support plate 232.

A circular hole 248B is provided in the seven rung portion 248A with uniform dimensions around the axis. A circular hole 232B is provided in the support plate 232 corresponding to the 20-circular hole 248B, and a nut plate 250 is welded to the upper surface of the circular hole 232B. As a result, the circular hole 248B of the flange portion 248A and the support plate 23

The shaft rod 244 fixed to the fixed base 238 and pivotally supported by the sliding base 248 limits the rotation of the support plate 232 when the support plate 232 reciprocates due to the rotation of the motor 224, and ensures that the rotation is only in the vertical direction. It has the role of guiding you to move to.

As shown in FIG. 9, a plurality of suction cup units 254 for sucking the photosensitive material 14 are attached to the support plate 232. This suction cup unit 254 sucks at least both ends of the photosensitive material 14 in the width direction.
(Multiple units are arranged according to the number of types of width dimensions)
Ru. In this embodiment, the number of photosensitive materials 14 applied in the width direction is three types, and the reference position and the end side in the width direction of the photosensitive material 14 are constant regardless of which photosensitive material 14 is used) and the other side of each photosensitive material 14. Suction cup unit 2 is placed at a position corresponding to the widthwise end of
54 units are provided (total of 4 units).

A through hole 232C is provided at the position of the support plate 232 where the suction cup unit 254 is attached.

A shaft 258A of a damper 258 that supports the suction cup base 256 passes through the through hole 232C.

The damper 258 supports the shaft 258A so as to be movable by a predetermined amount in the axial direction. The damper 258 has a flange portion 25.
8B is provided and fixed to the upper surface of the support plate 232 by bolts 260. Support plate 232 and suction cup base 25
A compression coil spring 262 is attached to the shaft 258A between the suction cup base 256 and the support plate 232.

Two small-diameter suction cups 264 (about 15 to 20 mm in diameter) are arranged side by side on the suction cup base 256 . For this reason, 1
The suction force of the photosensitive material 14 by the individual suction cup units 254 is not concentrated in one place, but can be suctioned over a relatively wide range. Therefore, for example, in order to obtain suction force with a single suction cup, the suction cup 264 of this embodiment only requires half the suction force.

The suction surface of the suction cup 264 and the inside of the suction cup base 256 are communicated with each other. Further, the suction cup base 256 is provided with a suction nozzle 256A, which is connected to the suction device 18 (see FIG. 2) via a tube 266. Suction device 18
is connected to a control device 800, and its operation is controlled by this control device 800).

Further, a solenoid valve 268 (see FIG. 6) attached to the moving member 202 is interposed in the intermediate portion of the tube 266. Solenoid valve 268 is connected to control device 800 . Here, by opening and closing the conduit in the electromagnetic valve 268, it is possible to control the suction and release of the suction of the photosensitive material 14 by the suction cup 264.

Here, when the photosensitive material 14 is adsorbed to the suction cup 264,
As shown in FIG. 5, the lower guide plate 12 is attached to the base plate 270 on the lower surface side of the photosensitive material 14.
4 is arranged, and the connecting shaft 230 is rotated by half a rotation,
This is done by moving the support plate 232 downward and sandwiching the photosensitive material 14 between the suction cup 264 and the lower guide plate 124. At this time, the suction cup base 256
2, the suction cup 264 and the lower guide plate 12 are moved toward each other against the biasing force of the compression coil spring 262.
The clamping force of the photosensitive material 140 between the two members is maintained substantially constant.

The photosensitive material 14 sucked by the suction cup 264 is sucked up by further rotating the connecting shaft 230 by half a turn, and in this state, the movable member 202 is moved along the rail 210 to move the photosensitive material 14 to the surface plate portion 300. The photosensitive material 14 is moved by a predetermined amount on the surface plate 302 and cut by the cutter 116, and further, the leading end of the photosensitive material 14 is conveyed to a predetermined position.

Here, when the moving member 2G2 is conveying, the intermediate portion of the photosensitive material 14 is held between the pair of rollers 104.

Therefore, the moving speed of this moving member 202 and the roller pair 1
Although it is necessary to synchronize the conveying speed of the moving member 202 with the conveying speed of the roller pair 104, in this embodiment, since the drive systems of the two are different, the moving speed of the moving member 202 is controlled to be slightly slower than the conveying speed of the roller pair 104. This prevents the photosensitive material 14 from falling off the suction cup 264. Furthermore, the slack (loop) of the photosensitive material 14 between the roller pair 104 and the suction cup 264 caused by this speed difference causes the shaft 1 of the upper guide plate 122 to
This is absorbed by rotation around 34.

Therefore, the light source unit 402 and the support plate 406 are moved back and forth on the surface plate 302.

As shown in FIG. 22, a fluorescent lamp 448 serving as a light source is disposed inside the casing 446, and is hooked to a pair of fluorescent lamp sockets 450 fixed to the lower end surface of the casing 446. A slit hole 446A is provided in the lower end surface of the casing 446, and an opening/closing shack 452 is attached to the casing 446 in correspondence with the slit hole 446A. A lens (

In this embodiment, the filter 480 has the slit holes 44
Six colors are arranged in a band shape along 6A, and are used depending on whether the photosensitive material used is negative type or positive type. In other words, R(
Six colors are arranged side by side: a red) filter, a negative and positive G (green) filter, a B (blue) filter, and a BK (black) filter. Therefore, negative and positive filters are attached to one filter sheet 478, making it unnecessary to replace them depending on the type of photosensitive material (negative or positive).

A shielding plate 488 is attached to one side of the rack 474 of the filter support plate 476 .

■Photosensitive material delivery section 500 As shown in FIG.
64 and conveyed to the photosensitive material delivery section 500. That is, a guide plate 502 is disposed adjacent to the surface plate 302, and the suction cup 264 is guided by the rail 210 and moved up to the guide plate 502.

A roller pair 504 is arranged downstream of the guide plate 502. 20. In the roller pair 504, one of them is a drive roller 504A that rotates at a speed V (constant V) under the driving force of a motor (not shown), and the photosensitive material 14 is sandwiched between it and the other driven roller 504B. This applies a conveyance force to the photosensitive material 14.

The shaft of the driven roller 504B is accommodated in a long hole 508 formed in the side plate 506 of the photosensitive material delivery section 500, and is movable in the direction of contact with and away from the drive roller 504A. In addition, the driving roller 504A and the driven roller 504
Ends of tension coil springs (not shown) are respectively engaged with the rotating shafts of the tension coil springs B, and the tension coil springs are biased in the direction of contacting each other by the biasing force of the tension coil springs.

Further, the driven roller 504B is connected to an actuator 512A of a solenoid 512 via a hanging bracket 510. The solenoid 512 is designed to pull in the actuator 512A when energized, and therefore,
When energized, the driving roller 504A and the driven roller 504B are separated from each other against the biasing force of the tension coil spring. In this state, the tip of the photosensitive material 14 attracted to the suction cup 264 is inserted into the gap between the driving roller 504A and the driven roller 504B.

In this embodiment, the drive roller 504A is rotated when the photosensitive material 14 is inserted into the gap, and is temporarily stopped after the photosensitive material 14 is inserted. Therefore, even if the tip of the photosensitive material 14 is slightly curled, it can be guided into the gap by the rotational force of the drive roller 504A, and when the solenoid 512 is de-energized, the photosensitive material 14 suddenly
transportation is prevented.

When the photosensitive material 14 is held between the roller pair 504,
The suction of the photosensitive material 14 by the suction cup 264 is released, and the moving member 202 is guided by the rail 210 and returned to its original position.

A roller pair 514 is further arranged downstream of the roller pair 504. This roller pair 514 also includes a drive roller 514A, one of which rotates by the driving force of a motor (not shown).
It is composed of a driven roller 514B that rotates in contact with this driving roller 514A. Here, the rotation speed of this drive roller 514A can be changed in three stages, the highest speed is the same as the speed V of the drive roller 514A, and the latter two speeds are slower than this rotation speed (VFIL VPAP□). Here, V F I L-
corresponds to the transport speed in the processor section 600 when the photosensitive material 14 is a film, and V P A P
The HR is set in accordance with the conveyance speed in the processor section 600 when the photosensitive material is paper.

An upper guide plate 516 and a lower guide plate 518 for guiding the front and back surfaces of the photosensitive material 14 are disposed between the roller pair 504 and the roller pair 514. A gap is provided between the upper guide plate 516 and the lower guide plate 518, and the photosensitive material 14 is conveyed through this gap.

The upper guide plate 516 is fixed to the side plate 506, and the lower guide plate 518 is fixed to the screw 5 through a hat-shaped bracket 520.
22 to the swing base 524. The swing base 524 extends in parallel to the lower guide plate 518 in the direction of the guide plate 502, and the side plate 50
A rotary shaft 526 is attached to the rotary shaft 526.

A helical gear 528 is fixed to the rotating shaft 526)
Ru. This helical gear 528 is connected to the rotating shaft 5 of the motor 53Q.
It meshes with a worm gear 534 attached to 32. The motor 530 has a self-braking function,
Even when the motor 530 is de-energized, the worm gear 5
34 is not rotated.

Here, the lower guide plate 5''18 is attached to the swing base 524.
The rotating shaft 526 is supported via the rotating shaft 526.
Since the helical gear 528 and the worm gear 534 are engaged with each other, the lower guide plate 518 is prevented from rotating around the rotation shaft 526 due to its own weight.

A shielding plate 538 extending in the radial direction of the rotating shaft 526 is attached to the rotating shaft 526.
A bracket 540 is installed on the side plate 506 corresponding to the movement trajectory of the
Two photoelectric sensors 542A and 542B are attached via. The photoelectric sensors 542A and 542B are each controlled by the control device 80.
connected to 0. Each of the photoelectric sensors 542A and 542B includes a light projecting section and a light receiving section, and the shielding plate 538 is arranged to fit between these sections.

One of the photoelectric sensors 542A and 542B is arranged in a position where the light emitting part and the light receiving part are blocked by the shielding plate 538 when the lower guide plate 518 is in the horizontal position (solid line position in FIG. 24), and the other The lower guide plate 518 is in the vertical position (24th
The shielding plate 538 is arranged at a position where the light emitting part and the light receiving part are blocked by the shielding plate 538 when the light emitting part and the light receiving part are in the imaginary line position). Therefore, the control device 800 controls the drive of the motor 530 based on the output signals of the photoelectric sensors 542A and 542B, and controls the drive of the lower guide plate 542.
18 can be positioned in said horizontal and vertical positions.

Further downstream of the downstream roller pair 514, a photoelectric sensor 544 is disposed below the conveyance path of the photosensitive material 14. This photoelectric sensor 544 is connected to the control device 800. Here, the output of the photoelectric sensor 544 changes depending on the presence or absence of the photosensitive material 14, so that the control device 800 can recognize the leading and trailing ends of the photosensitive material 14.

Here, when the photosensitive material 14 held between the upstream pair of rollers 504 is conveyed, the downstream roller pair 514 is rotated at the same speed as the upstream roller pair 504. Therefore, upstream and downstream roller pairs 504.514
The photosensitive material 14 held between the two is transported under a predetermined tension. Here, when the leading end of the photosensitive material 14 is detected by the photoelectric sensor 544, the rotational speed of the downstream roller pair 514 is reduced to a low speed (V, L, or 1 tV, APER) depending on the type of the photosensitive material 14. It looks like it's going to be done. At the same time or slightly earlier, the motor 53
0 is driven, and the lower guide plate 518 is rotated in the vertical position direction. Therefore, the photosensitive material 1 caused by the difference in conveying speed between the upstream and downstream roller pairs 514
4 can be formed in the space below where the lower guide plate 518 does not exist.

Further, a tray 546 is disposed at the lowest part of this lower space, and serves as a storage portion when the rear end portion of the photosensitive material 14 is removed from the upstream o-ra pair 504.

■Processor section 600 As shown in FIG. It is held between the pair 604. Of the twenty roller pairs 604, one of which is a driving roller 604A that rotates by the driving force of a motor (not shown), and the other is a driven roller 60 that rotates by receiving the driving force from this driving roller 604A.
It is said to be 4B. The rotational speed of the drive roller 604A is
The rotational speed (V, □) of the downstream roller pair 614 at low speed

Here, as shown in FIG. 26, the downstream roller pair 51
The drive roller 514A of No. 4 has a one-way clutch 606 between its rotating shaft 514C and the rotating shaft 515 of the motor.
is interposed so that when the outer periphery of the roller is rotated at a speed faster than the rotational speed of the motor, the roller and the rotating shaft are rotated relative to each other.

It is locked to. As a result, the lid body 730 is biased by the biasing force of the torsion coil spring 736 in the direction of closing the rectangular hole 726 (in the direction of arrow B in FIG. 29). Lid body 73
A felt-like light-shielding member 738 is pasted around the rectangular hole 726 that the opening periphery of 0 comes into contact with, and prevents light from entering the exposure section 400 from the film loading section 700 when the lid 730 is closed. .

A bracket 740 having a U-shaped cross section is attached to the inner bottom surface of the lid body 730, and a shaft 742 is hooked between leg plates 740A that are parallel to each other. A roller 744 is supported on this shaft 742 .

As shown in FIG. 28, the support base 728 is frame-shaped and has a pair of shafts 746 attached at three locations on its outer side facing the guide shirt 720. The pair of shafts 746 are spaced apart from each other in the vertical direction, and each has a roller 748 supported thereon. The peripheral surfaces of these rollers 748 are brought into contact with the upper and lower outer peripheral surfaces of the guide shaft 718 or the guide shaft 720.

Further, as shown in FIG. 30, a bracket 750 is disposed between the pair of shafts 746.

The hook is extended, and a roller 754 is pivotally supported in the middle part. The circumferential surface of this roller 754 corresponds to the guide shaft 71
8 or the outer peripheral side surface of the guide shaft 720. As a result, the support base 728 is supported by the guide shaft 718 or the guide shaft 720 at a total of six locations (three rollers 748, 754 per location) and is slidable in the axial direction of the guide shaft 718, 720. It is said that

The guide shaft 720 is the guide shaft 7 of the large lid 24.
18, the ends of which are separated from each other), but when the support base 728 is moved in the direction of the guide shaft 718 of the large lid 24, the rollers 748 and 754 on the tip side in the moving direction are separated from the guide shaft 720. However, it is configured to be supported by a guide shaft 718 of the large lid 24. Here, when the rollers 748 and 754 are detached from the guide shaft 720, the support base 728 is attached to the guide shaft 72 at the other four locations.
0. Therefore, during movement, the support base 728 is supported by the guide shafts 720 or 718 at both widthwise ends of the support base, and is supported at at least two locations along the movement direction. Therefore, the support base 728 passes through the rectangular hole 726 and is smoothly passed between the guide shaft 720 on the exposure section 400 side and the guide shaft 718 on the film loading section 700 side.

Here, as shown in FIG. 29, when the support base 728 is moved from the exposure section 400 to the film loading section 700, the roller 744 of the lid 7.30 closing the rectangular hole 726 20 roller 7
44, a rotational force is applied to the lid body 730 in the opening direction of the rectangular hole 726 around the shaft 734. Therefore, as the support base 28 is further moved, the roller 744 is transferred from the side surface to the bottom surface of the support base 728, and the lid body 730 is rotated against the biasing force of the torsion coil spring 736. It has become. That is,
The lid 730 is automatically opened as the support base 728 moves.

As shown in FIG. 29, a closing member 756 is attached to the rearmost side surface of the support base 728 in the direction of movement toward the film loading section 700. A circular hole 756A is formed at both ends of the closing member 756 in the longitudinal direction, and the guide shaft 720 passes through the circular hole 756A.

The closing member 756 has a flange portion 756B in which the imaging portions on three sides excluding the upper side are bent at approximately right angles. This flange portion 756B is configured to face the peripheral edge of the rectangular hole 726 when the support base 728 is moved to the film loading section 700. A felt-like light shielding member 758 (see FIG. 29) is attached to the peripheral edge of this rectangular hole 726. As this light shielding member 758, the female side of Magicross (trade name) or the like can be used. Further, a flange portion 760 bent at a substantially right angle is fixed to the upper side of the rectangular hole 726, and its tip portion faces the upper piece of the closing member 756. This closing member 75
A light shielding member 762 is attached to the upper piece of 6. As a result, the support base 728 pushes open the lid body 730 and moves to the film loading section 700Δ, and when the closing member 756 is in contact with the rectangular hole 726, the rectangular hole 726
This prevents light from entering the exposure section 400.

Further, an oil seal (not shown) is interposed between the guide shaft 720 and the circular hole 756A through which the guide shaft 720 passes, to prevent light from leaking from the round hole 756A.

As shown in FIG. 28, a pair of brackets 764 are fixed to the back of the closing member 756 at both longitudinal ends thereof. This bracket 764 extends at an upper portion of the closing member 756 at a substantially right angle in a direction away from the closing member 756, and further extends at its distal ends in a direction away from each other. The tip of the second extension part is locked to a part of the chain 766 via a screw. chain 76
6 is a bracket attached to the plate inspection device 10 at both ends of the guide shaft 720 in the axial direction) 768 (Only the right side is shown in FIG. 28)
It is wound around a pair of sprockets 770 attached via the sprocket 770 to form a loop.

The sprockets 770 on the front side of the plate inspection device 10 are each coaxially fixed to one shaft 772 and are driven together.

A shielding plate 790 is attached to one of the pair of brackets 764 and is suspended downward from the device. This shielding plate 790 is moved together with the support plate 728, and two photoelectric sensors 792 are arranged on the movement locus of this shielding plate 790. Photoelectric sensor 79
2 are attached near both ends in the axial direction of a guide rail 720 in the plate inspection making device 10, and the shielding plate 790 passes between the light projecting section and the light receiving section. This photoelectric sensor 792 has the role of controlling the amount of movement of the support plate 728 by the motor 776 and positioning the support plate 728 at a predetermined position in the exposure B400 and film loading section 700. Note that the support plate 7
28 is positioned at a predetermined position in the film loading section 700 and the closing member 756 and light shielding members 758 and 762 prevent light from entering the exposure section 400 from the rectangular hole 726, then the small lid 704 is closed. Since the lock is released, open the small cover 704 and insert the document film 1 through the rectangular hole 702.
6 can be loaded. When the support foot door 28 is in a position that straddles the exposure section 400 and the lens loading section 700, the small lid 704 is not unlocked and the rectangular hole is closed. [) 2 is prevented from entering the exposure section 400.

A gear 774 is fixed to an axially intermediate portion of the shaft 772, and is connected to a gear 776B attached to a rotating shaft 776A of a motor 776 via a chain 778. Here, when the motor 776 is driven, the shaft 772 is rotated via the chain 778, thereby making it possible to drive the chain 766. By driving the chain 766, the support base 728, which is fixed to a part of the chain 766 via the bracket 764, is moved in the axial direction of the guide shaft 720.

A pair of shafts 780 are provided between side surfaces 728A and 728B of the support base 728, which correspond to both ends of the guide shaft 720 in the axial direction. One shaft 780 is connected to a rotating shaft 782A of a motor 782. A gear 780A is fixed to the inner side of the side surfaces 728A and 728B of the shaft 780, and an endless chain 784 is wound around the gear 780A, and the chain 784 is driven by the drive of the motor 782. chain 784
A transparent overlay 708 is attached to the opening. The area of this overlay sheet 708 is approximately the same as the opening area of the support base 728, and the overlay sheet 708 has an area approximately equal to the opening area of the support base 728,
is arranged below and above the gear 780A.

Furthermore, a positioning plate 786 for positioning the original film 16 is attached to the upper surface of the support base 728 on the side nearer to the plate inspection device 10 .

As shown in FIG. 31, this positioning plate 786
A metal size plate 788 is fixed to the plate with double-sided adhesive tape. Three knock pins 788A are formed on this size plate 788 to protrude along the length direction of the size plate 788. Of the three knock pins 788A, the seven knock pins 788A on one end side of the size plate 788 are protrusions with an oblong cross section, and the other two knock pins 788A are protrusions with a circular cross section. The oval knock pin 788A fits into the elongated hole 1 provided in the original film 16.
6A, and the other two knock pins 788A have an outer diameter dimension that allows them to be easily inserted into the elongated hole 16A. Here, the method of fixing the positioning plate 786 and the size plate 788 is not limited to the method using adhesive tape,
A method such as magnetically attaching the size plate 788 using magnetic force may also be used.

Here, when loading the original film 16, with the support base 728 placed in the original loading section 700, the overlay sheet 708 is placed below the gear 780A,
Loading is completed by inserting the dowel pin 788A into the circular hole 16A of the original film 16 and supporting the original film 16 on the overlay sheet 708.

On the other hand, when placing the original film 16 on the photosensitive material 14 placed on the surface plate 302, with the support base 728 placed on the exposure section 400, the motor 782 is driven to move the overlay sheet 708 onto the gear 780A. I'm trying to move it to the top. In this state, the photosensitive material 14, the original film 16, and the overlay sheet 708 are arranged in layers on the surface plate 302 in this order.

■Control device 800 The control device 800 is the intermediate base 20 of the plate inspection device 10.

As shown in FIG. 32, the control device 800 includes a microcomputer 802. The microcomputer 802 includes a CPU 804, a RAM 806,
It is composed of a ROM 808, an input/output port 810, and a bus 812 such as a data noise or control bus that connects these.

The human output port 81O of the microcomputer 802 is connected to the signal lines of the respective parts (■ to ■). That is, in the magazine loading section 100, the signal line of the limit switch 114 is connected, and is connected to the cutter 116 via the driver 814.

In the photosensitive material transport section 200, a photoelectric sensor 220 is connected, a motor 218 is connected through a driver 816, a motor 224 is connected through the driver 818, and a solenoid valve 268 is connected through a driver 820, respectively.

are connected to each other. Although not shown,
A signal line for supplying a drive signal for driving each pair of rollers in the processor section 600 is also connected.

In the film loading section 700, a photoelectric sensor 792 is connected, a motor 776 is connected through a driver 846, and a motor 782 is connected through a driver 848.

The operation of this embodiment will be explained below with reference to the control flowcharts shown in FIGS. 33 to 42.

First, step 1000 of the main routine (Figure 33)
, when the activation switch is turned on, step 1
002) to initialize each part (see initial setting routine in Figure 34). The magazine loading section 100 loads the magazine 102 into the magazine loading port 106. At this point, a light reflecting sheet 110 is attached to the magazine 102 so that the light from the photoelectric sensor 114 passes through the rectangular hole 112 provided in the back wall 106A of the magazine loading port 106 and returns to the photoelectric sensor 114. It's happening. The number and position of the light reflection channels 110 to be attached are determined depending on the size and type of the photosensitive material 14 housed in the magazine 102. Therefore, the control device 800 can recognize the size and type of the loaded photosensitive material 14 based on the on/off signal of the photoelectric sensor 114 (step 1100).

In the next step 1102, the photosensitive material transport section 200
Then, it is determined whether or not the moving member 202 is detected by the photoelectric sensor 220 on the left side of FIG. 2, and if it is not detected, the motor 218 is driven. The motor 218 drives the chain 214 via the sprocket 216, and the movable member 202 is moved along the rail 210 and stopped to the left in FIG. In this position, the suction cup 264
is deviated from above the surface plate 302 and placed onto the lower guide plate 124 with a slight gap. Also, in this position, the photosensitive material squeeze roller 274 climbs up to the cam plate 276, so the lower guide plate 124 and the photosensitive material squeeze roller 274
There is also a gap between the two and the photosensitive material 14 through which the photosensitive material 14 passes.

Next, in step 1104, the surface plate 30 of the surface plate section 300
2 to the lowest position. It is determined whether or not the shielding plate 356 is detected by the photoelectric sensor 354C. If the shielding plate 356 is not detected, the motor 348 is driven, and the driving force of the motor 348 is used to move the rack 3 through the gear box 350.
Move 40 downward. The shielding plate 356 is the photoelectric sensor 3
The surface plate 302 is stopped when it is placed between the light projecting section and the light receiving section of 54C, and thereby the surface plate 302 is stopped at a position flush with the lower guide plate 124.

In the exposure section 400, in step 1106, the support plate 406, which is hung on the rail 404, is placed in front of the plate inspection device 10.

At this time, the squeeze roller 438 rotates around its rotating shaft 438.
A is mounted on the cam bracket 444 and held there.

In the photosensitive material delivery section 500, it is determined in step 1108 whether or not the shielding plate 538 is detected by the photoelectric sensor 542A. If the shielding plate 538 is not detected, the motor 53
0 is driven, the worm gear 534 attached to the rotating shaft 532 is rotated, and the helical gear 528 is rotated. The rotation shaft 52 is rotated by the rotation of the second helical gear 528.
G is rotated counterclockwise in FIG. Thereby, the lower guide plate 518 can be rotated toward the horizontal position (the solid line position in FIG. 24). Here, lower guide plate 5
18 is in the horizontal position, the shielding plate 538 is detected by the photoelectric sensor 542A, and the driving of the motor 530 is stopped. This motor 530 has a self-braking function, and the engagement between the helical gear 528 and the worm gear 534 prevents the lower guide plate 518 from rotating to the right in FIG. 2 due to its own weight. It is held in said horizontal position.

In the film loading section 700, in step]110, it is determined whether the shielding plate 790 is detected by the photoelectric sensor 792 on the right side in FIG. 2 of the plate inspection device 10. If the photoelectric sensor 792 does not detect the shielding plate 790, the motor 776 is driven. The drive of this motor 776 rotates the sprocket 770 and drives the chain 766. Since the support base 728 is fixed to a part of the chain 766 via a bracket 768, the support base 728 moves to the right in FIG. 2 of the plate inspection device 10 as the chain 766 is driven. When the support base 728 moves, it presses a roller 748 attached to the lid 730 and rotates the lid 730 around the shaft 734 against the biasing force of the torsion coil spring 736. Therefore, it can pass through the rectangular hole 726 and move to the film loading section 700. Here, the driving of the motor 776 is stopped when the shielding plate is detected by the photoelectric sensor 792 on the right side of FIG. 2 of the plate inspection device 10. As a result, the support bases 7 to 8 are positioned in the film loading section 700. In addition, in the second state, the support base 7
28 closing members 756 close the rectangular hole 726 through the light shielding members 758 and 762, so that the film loading section 700
It is possible to prevent light from entering the light exposure section 400.

Further, the overrain door 08 is held in a downwardly disposed state of the gear 780A by the drive of the motor 782.

A size plate 788 corresponding to the applied original film 16 is magnetically attached to the positioning plate 786. The original film 16 is provided with a circular hole 16A, and the original film 16 can be loaded by inserting it into the knock pin 788A provided on the size plate 788 and placing the original film 16 on the overlay sheet 708. Complete.

When the initial settings of each part are completed, the process moves to step 1004 of the main routine, and initial photosensitive material transport control iI (see FIG. 35) is performed.

First, the photosensitive material 14 is pulled out from the outlet 108 of the magazine 102 and conveyed upward in FIG.
00, the roller pair 104 is driven, and the roller pair 1
04 and the conveyance direction is changed by 90 degrees (
Step 1200).

The photosensitive material 14 whose direction has been changed passes through the cutter 116 and is guided by the guide plate 120, and is guided by the lower guide plate 12.
4 and the suction cup 264. At this time,
Since the gap between the upper guide plate 122 and the lower guide plate 124 is set to a predetermined size (approximately 3 mm) by the damper 144, even if the tip of the photosensitive material 14 is slightly curled,
It is reliably transported in a predetermined direction. At the knee, the photosensitive material squeeze roller 274 climbs up onto the cam plate 276, and since the rotating shaft 274A is placed at the upper end of the elongated hole 272A, the photosensitive material 14 and the photosensitive material squeeze roller 274 interfere with each other. Never.

After the photosensitive material 14 has been conveyed a predetermined amount such that its leading end passes through the gap (step 1202), the conveyance by the roller pair 104 is stopped (step 1204).

Next, in step 1206, when the motor 224 is driven, the cam 228 rotates by half a rotation via the gear box 226. This rotation of the cam 228 causes the connecting shaft 230 to rotate to the cam 2.
28 and lowers the bearing 234. Bearing 234 is brat 236A, 236
Since it is fixed to the support plate 232 by B, the support plate 232 is lowered. Here, the support plate 232 is attached to the movable member 2D2 by the shaft rod 244 via the fixed base 238.
Since it moves while being guided by the moving member 202, it maintains a parallel state with the moving member 202 and descends without being rotated relative to it.

As the support plate 232 descends, the lowermost end of the suction cup 264 comes into contact with the photosensitive material 14, and this suction cup 264 and the lower guide plate 12
4, the photosensitive material 14 is held between them. In this state, in step 1208, the electromagnetic valve 268 communicating with the suction device 18 is opened, and the photosensitive material 14 is sucked by the suction cup 264. Here, the suction cup units 254 are provided at four locations including a reference position according to the width direction size of the photosensitive material 14, and the suction cup units 254 are provided at four locations according to the width direction size of the photosensitive material 14 detected by the photoelectric sensor 114. Since the electromagnetic valve 268 interposed between the photosensitive material 18 and the photosensitive material 18 is controlled to determine which suction cup 264 is to be activated for suction, the suction cup 264 that does not hold the photosensitive material 14 does not generate any suction force.

As the cam 228 further rotates by half a rotation while the photosensitive material 14 is being attracted (step 1210), the support plate 232 returns to its initial position.

Here, the suction cups 264 of this embodiment have a small diameter, and two suction cups 264 are provided in each suction cup unit 254.

For this reason, when large diameter suction cups are arranged one by one, suction cup 1
The suction force of one suction cup 2 applied to this embodiment
Since the adsorption force at 64 can be reduced and there are many places where the photosensitive material 14 is adsorbed, there is no possibility that the photosensitive material 14 will meander greatly in the thickness direction when the photosensitive material 14 is adsorbed.

In the next step 1211, the roller pair 104 is driven at a conveying speed V, and then in step 1212, the suction cup 2
With the photosensitive material 14 adsorbed by the motor 21
8 to move the moving member 202 along the rail 210 at a speed V□ lower than the transport speed V of the roller pair 104.
Move it to the right in Figure 2 (V). Further, the photosensitive material squeeze roller 274 descends from the cam plate 276 and is placed on the surface plate 302 via the photosensitive material 14. For the second time, the photosensitive material 14 is dragged along with the moving member 902 without being rotated.

With this, the roller pair 104 and the suction cup 264 are set at different conveyance speeds.
There is slack (loop) in the thickness direction in the photosensitive material 14 between
will be formed. This loop behaves depending on the conveyance speed difference, and the upper guide plate 12 follows this behavior.
2 rotates around the shaft 134, and the gap size between the upper guide plate 122 and the lower guide plate 124 is changed. That is, by pushing up the upper guide plate 122 due to the stiffness of the photosensitive material 14, the loop may be crushed or the photosensitive material 14 may be pushed up.
jamming within the guide plate 120 is prevented.

When the photosensitive material 14 is conveyed by a predetermined amount according to the size detected by the photoelectric sensor 114 (step 1214>,
The movement of the moving member 202 is temporarily stopped, and the roller pair 1
04 is stopped (step) 216.121
7), actuating the cutter 116 (step 1218);
The photosensitive material 14 is cut. Thereby, it is possible to separate the roll-shaped photosensitive material 14 and the photosensitive material 14 of a predetermined size.

When cutting by the cutter 116 is completed, step 122
0, the movement of the moving member is resumed, and the photosensitive material 1
4 is conveyed to a predetermined position on the surface plate 302 (steps 1222 and 1224).

Also, due to this movement, the photosensitive material 1 is removed from the roller pair 104.
4 is separated, so that the loop is connected to the upper guide plate 122.
As a result, the photosensitive material 14 becomes approximately straight. Further, since the lowering of the upper guide plate 122 is stopped by absorbing the impact by the damper 144, there is no problem of the photosensitive material 14 being crushed by the inertial force when the photosensitive material 14 is pushed down and rotated.

When the tip of the photosensitive material 4 is placed at a predetermined position on the surface plate 302, in step 1226, the motor 224 is rotated and the cam 228 is rotated by half a rotation.

As a result, the photosensitive material 14 is held between the suction cup 264 and the surface plate 302. Here, the electromagnetic valve 326 communicating with the suction device 18 is opened, and the photosensitive material 14 is sucked through the plurality of holes 308 provided in the surface plate main body 306 (
Step 1228).

The surface plate 302 has a three-layer structure in which the pattern forming plate 310 is sandwiched between the surface plate main body 30B and the base plate 312, and can generate suction force for each pattern space according to the size of the photosensitive material 14. Therefore, air is sucked into the pattern space through the holes 308 only in the area where the photosensitive material 14 is placed, so that the photosensitive material 14 can be reliably adsorbed without any unnecessary suction. . The suction of the photosensitive material 14 by the surface plate 302 continues until the exposure process of the photosensitive material 14 is completed and the photosensitive material 14 is conveyed from the surface plate 302.

Since the pattern forming plate 310 is made of a sponge-like soft material, even when there are many pattern spaces (eight locations) as in this embodiment, each pattern can be formed by a simple punching operation. It has good performance and can reduce costs. In addition, this pattern forming plate 31
A spacer 318 is inserted into the circular hole 316 of 0, and when clamped between the surface plate main body 306 and the base plate 312 with screws 32 [), the axial dimension of the spacer 318 (2
The pattern can be reliably formed because the pattern is only crushed to a depth of mm). Note that since the sponge-like soft member applied to the pattern forming plate 310 is a closed cell, air will not leak.

Next, in step 1230, the suction of the photosensitive material 14 by the suction cup 264 is released and the cam 228 is rotated half a turn again, thereby separating the photosensitive material 14 and the suction cup 264. At this time, the photosensitive material squeeze roller 274 remains placed on the photosensitive material 14.

When the suction of the photosensitive material 14 by the suction cup 264 is released and the moving member 202 is separated from the photosensitive material 14, the moving member 202 moves to the -rotation front part and then returns to the initial position along the rail 210 ( Step 1232). At this time,
The photosensitive material squeeze roller 274 is moved while rotating over the photosensitive material 14. Thereby, air bubbles generated between the photosensitive material 14 and the surface plate 302 can be squeezed out, and the photosensitive material 14 can be brought into close contact with the surface plate 302. That is, in cases where the peripheral edge of the photosensitive material 14 cannot be reliably adsorbed only by suction through the holes 308 of the surface plate 302, or when the photosensitive material 14 itself is deformed in the thickness direction due to the surrounding environment, etc. Even in such a case, the squeezing action of the photosensitive material squeeze roller 274 ensures that the photosensitive material is brought into close contact with the surface plate 302.

Next, in step 1006 of the main routine, surface plate standby control (see FIG. 36) is performed.

At step 1300, the two motors 348 are driven synchronously to move the rack 340 upward in FIG. 2 via the gearbox 350.

The surface plate 302 is provided with two slide shafts 364,
Since the vertical movement of the surface plate 302 is guided by this slide shaft 364, the surface plate 302 is moved vertically while maintaining a state parallel to the intermediate base 20 by the drive of the motor 348.

Here, when the shielding plate 356 is detected by the photoelectric sensor 354B (step 1302), the drive of the motor 348 is stopped (step 1304).

Next, in step 1008 of the main routine, original film transport control (see FIG. 37) is performed.

First, in step 1400, in the film loading section 700, with the document film 16 set, the motor 776 is driven to move the support base 728 to the exposure section 400 along the guide shafts 718 and 720.

Here, with the shielding plate 790 detected by the photoelectric sensor 792 on the left side of FIG. 2 (step 1402), the support base 72
8 is stopped (step 1404).

When the support base 728 is located in the film loading section 7[)O, the guide shaft 718 and rollers 748.75
It is supported through 4. This guide shaft 718 is separated from the guide shaft 720 of the exposure section 400 at the side surface where the rectangular hole 726 is provided. However, roller 7
48.754 are provided at six locations (three locations on each side) on the support base 728, and as the support base 728 moves, the rollers 748.754 at the tip of the moving direction are guided by the shaft 718.
Even if the roller 748 at the tip of this
．． 854 can smoothly transition from guide shaft 718 to guide shaft 720. In addition, the intermediate roller 74
8.754 is from the guide shaft 718 to the guide shaft 72
When moving to 0, the leading roller 748.754 is supported by the guide shaft 720, and the trailing roller 748.754 is supported by the guide shaft 720.
Since it is supported by the guide shaft 718, it can be moved smoothly. Further, in the rear end rollers 748, 754, the leading and middle rollers 748, 754 are supported by the guide shaft 720, so that they can be smoothly moved. That is, since the support base 728 is supported to the guide shaft 718 or 720 in at least four places,
Even if the guide shaft 718 and the guide shaft 720 are separated from each other, their movement is smooth.

As the support base 728 moves to the predetermined position of the exposure unit 400, the lid 7 opened by the support base 728
30 is a torsion coil spring 736 centered around a shaft 734.
, and closes the rectangular hole 726 via the light shielding member 738. Therefore, light can be prevented from entering the exposure section 400 through the rectangular hole 726.

Note that when the support base 728 is at a predetermined position in the exposure section 400, the overlay sheet 708 and the surface plate 302 are at a position slightly separated from each other.

Next, in step 1010 of the main routine, exposure standby control (see FIG. 38) is performed.

First, in step 1500, the motor 782 attached to the support base 728 is driven, and the chain 784
drive. As a result, the over rain door 08
The gear 780 on the back side of the device is moved together with the chain 784.
It is reversed at A and moved above the gear 780A.

By this operation, the original film 16 placed on the overlay door 08 is placed onto the photosensitive material 14.

When the overlay sheet 708 is placed above the gear 780A and the original film 16 is placed on the photosensitive material 14, the process moves to step 1502, where the motor 348 is driven again and the surface plate 302 is further raised. Here, when the photoelectric sensor 354A detects the shielding plate 356 (step 1504), the driving of the motor 348 is stopped (step 1506), and the raising of the surface plate 302 is stopped. In this state, the surface plate 302 and the positioning plate 786 are positioned, and the photosensitive material 14, original film 16, and overlay sheet 708 are stacked in contact with each other.

Here, when the electromagnetic valve 336 communicating with the suction device 18 is opened, a suction action is generated in the groove 328 formed in the surface plate main body 306, and the peripheral edge of the overlay sheet 708 placed on this groove 328 is suctioned. (Step 1508). Thereby, the photosensitive material 14 and the original film 16 can be held between the surface plate 302 and the overlay sheet 708.

When the overlay sheet 708 is attracted to the groove 328 for a predetermined period of time, the motor 436 of the exposure unit 400 starts driving in step 1510) and step 1512. This motor 436 is driven by a belt 434 and a wheel 4.
32 to the shaft 430, and the sprocket 424 rotates. This allows the sprocket 424
A chain 426 wound around the device is driven, and the support plate 406 is moved along the rail 404 from the front side of the device to the back side.

At this time, the squeeze roller 438 that had climbed up to the high part 444A of the cam bracket 444 moves to the slope part 444B.
It is placed on the surface plate 302 via an overlay (708). Rail 404 of support plate l-406
As the squeeze roller 438 moves along the overlay sheet 708, the squeeze roller 438 rotates and moves on the overlay sheet 708. Also, a photosensitive material 14, an original film 16, an overlay sheet 708
is brought into close contact with the surface plate 302 by suction. As a result, the air between the overrain door 08 and the surface plate 302 is pushed out, and the photosensitive material 14 and the original film 1 are placed on the surface plate 302.
6 can be completely brought into close contact with each other.

When the support plate 406 reaches the rear end of the device, the squeeze roller 438 is gradually separated from the overlay sheet 708 by the cam bracket 444. Support plate 4
When 06 is stopped, in step 1514, solenoid 442 is energized and actuator 442A retracts. As a result, the squeeze roller 438 is lifted and held via the hanging bracket 440. Here, since the squeeze roller 438 climbs up the cam bracket 444, the distance over which the load of the squeeze roller 438 is applied during the lifting stroke is short, and a small solenoid 442 with a small excitation force can be used.

Next, in step 1012 of the main routine, exposure processing control (see FIG. 39) is performed.

First, in step 1600, the type of original film 16 (Y, M) is selected by driving the motor 468.

A filter (one of B, G, R, and black) corresponding to the type (positive, negative) of the photosensitive material 14 is placed on the slit hole 476A.

Further, in step 1602, when the support plate 406 returns to its original position from the back side of the apparatus, the solenoid 456 is driven, the opening/closing shutter 452 is opened, and the slit hole 446A is opened. Therefore, the light beam from the fluorescent lamp 448 passes through the lens (for example, Selfoc lens) to the slit hole 4.
Irradiated from 46A.

In this state, by moving the support plate 406 to its original position (step 1604>, the original film 16
The image is printed onto the photosensitive material 14.

Next, in step 1014 of the main routine, original film exchange control (see FIG. 40) is performed.

When the support plate 406 returns to its original position, the surface plate 302
As the motor 348 moves (step 1700), it is lowered to a position where the photoelectric sensor 354B detects the shielding plate 356 (steps 1702 and 1704). Next, in step 1706, the support base 7 of the film loading section 700 is
A motor 782 attached to the chain 784 rotates in the same direction as described above, and the overlay sheet 708 rotates half a rotation as the chain 784 is driven. Thereby, the original film 16 can be placed on the overlay sheet 708 again. Note that the solenoid valve 336 is closed when the overlay door 08 is moved, and the overlay door 08 is closed.
8 onto the surface plate 302 has been stopped. When the original film 16 has been placed on the overlay door 08, the process moves to step 1708, where the support base 728 is driven by the motor 776 and moved to the film loading section 700, where it is supported by the guide shaft 718. . At this point, the lock of the small lid 704 is released, so the handle 7C of the small lid 704
16, open the small lid 704, replace it with the next color-separated original film 16, and repeat the above exposure control a predetermined number of times (step 1016 of the main routine). , the film is moved to the film loading section 700, and is placed on standby while being supported by the guide shaft 718, and then step 1 of the main routine is performed.
The process moves from step 016 to step 1018, where exposed photosensitive material transport control (see FIG. 41) is performed.

First, in step 1800, the surface plate 302
48, it descends to the lowest position where the photoelectric sensor 354C detects the shielding plate 356 and is stopped (step 18
02.1804).

Next, the motor 218 of the photosensitive material conveying section 200 is driven (step 1806), and the moving member 202 is moved to the rail 210.
is moved along. When the suction cup 264 is moved a predetermined amount to the tip of the photosensitive material 14 (step 1808), the movement of the moving member 202 is stopped (step 1810),
Proceeding to step 1812, the motor 224 is driven. As a result, the support plate 232 is lowered, and the photosensitive material 14 is held between the suction cup 264 and the surface plate 302. Here, the solenoid valve 268 communicating with the suction device 18 is opened and the suction cup 268 is opened.
, 1 to suck the photosensitive material 14 and release the suction of the photosensitive material 14 by the surface plate 302 (step 1814), and raise the support plate 232 again to hold the photosensitive material 14 in the suctioned state (step 1816). Note that at this time, the solenoid valve 326 is closed, and the surface plate 30 of the photosensitive material 14 is closed.
Adsorption onto 2 has been stopped.

Here, in the next step 1818, the moving member 202 is further moved in the same direction to move the suction cup 264 onto the guide 502, and then the process moves to step 1820 to start rotating the drive roller 504A. At this time, the solenoid 512 is activated and moves the driven roller 504B in the direction away from the drive roller 504A. As a result, even if the tip of the photosensitive material 14 adsorbed by the suction cup 264 is slightly curled, it is easily guided between the drive roller 504A and the driven roller 504B, and can be reliably inserted between the rollers.

When the suction cup 264 reaches the leading edge and is stopped (step 1
822), the rotation of the drive roller 504A is temporarily stopped (step 1824), and the operation of the solenoid 512 is stopped (step 1826).

This causes the driven roller 504B to move to the drive roller 504.
It is moved in the direction of contact with A, and the photosensitive material 14 is held therebetween. Next, in step 1828, the suction of the photosensitive material 14 by the suction cup 264 is released, and the moving member 202 retreats along the rail 210 and returns to its original position.

In the next step 1830, the drive roller 504A is restarted to rotate at a speed V to transfer the photosensitive material 14 to the bromo/transfer section 6.
Transport in direction 00.

Next, in step 1020 of the main routine, photosensitive material delivery control (see FIG. 42) is performed.

First, in step 1900, the roller pair 514 starts rotating at the same speed as the roller pair 504.

Therefore, the photosensitive material 14 is held and conveyed by the pair of rollers 504, guided to the gap between the upper guide plate 516 and the lower guide plate 518, and is also held and conveyed by the pair of rollers 514.

Here, when the tip #7J of the photosensitive material 14 reaches the top of the photoelectric sensor 544 in step 1902, the photoelectric sensor 544
is detected, and the motor 530 is driven (step 1904).

By driving this motor 530, the helical gear 528 is rotated via the worm gear 534, and the rotation shaft 526 is rotated through the worm gear 534.
Figure 4: Rotate clockwise. As a result, the lower guide plate 51
8 is rotated along with the swing base 524 from the solid line position in FIG. 24 to the imaginary line position, and the lower surface of the photosensitive material 14 is opened.

Next, in step 7 1906, the conveying speed of the roller pair 514 is reduced to the same speed (VFILK or VPAPER) as that of the processor unit 600, which is slower than the speed V. This causes slack in the photosensitive material 14 between the roller pair 504 and the roller pair 514, and this slack is formed into a substantially U-shape. When the rear end of the photosensitive material 14 passes the roller pair 504, the photosensitive material 14 is stored in the tray 546 while being held by the roller pair 514.

The photosensitive material 14 is transferred to the roller pair 604 of the processor 9600.
sandwiched between. The conveyance speed of the roller pair 604 is slightly faster than the conveyance speed of the roller pair 514. Therefore, the photosensitive material 14 is conveyed under tension between the roller pair 514 and the roller pair 604. Here, since a one-way clutch 606 is attached to the roller pair 514, a predetermined tension state can be maintained.

The photosensitive material 14 is gradually conveyed to the processor section 600, and when the rear end of the photosensitive material 14 passes the roller pair 514 and the photoelectric sensor 554 (step 1908), a signal from the photoelectric sensor 544 causes the motor to 530 is reversed, and in step 1910>, the lower guide plate 518 is rotated from the imaginary line position in FIG. 24 to the solid line position via the swing base 524. As a result, the next photosensitive material 1
4 can be reliably guided.

Next, in step 1022 of the main routine, development processing is performed. That is, in the processor section 600, the photosensitive material 14 is first immersed in developing tanks 612 and 614, guided by the pair of rollers 624 of the processing rack 622 and the guide plate 62B, and conveyed in an abbreviated shape. They are transported and processed in the order of tanks 618 and 620. The processed photosensitive material is transferred to a drying section 640 by a pair of rollers 642.
The drying section 640 is guided to a roller pair 643 of the drying section 640 and conveyed by the roller pair 643 . During this transportation, the fan 648 and heater 650
The drying process is performed by discharging the hot air generated by the duct 644 from the opening 646 of the duct 644 and applying it to the photosensitive material 14. The photosensitive material 14 that has undergone the drying process is taken out from an exit port 22 formed in the casing 12.
