Abstract

PURPOSE:To simplify the structure of a delivering part by stopping a guide member at a prescribed position at the lower side of a photosensitive material carrying passage at the time of the delivery of the tip end part of photosensitive material from a surface table part to a processor part. CONSTITUTION:At the photosensitive material delivering part 500, a motor 530 is driven, and a worm gear 534 is driven, and a rotary shaft 526 is rotated through a helical gear 528 until a shield plate 538 is detected by a photoelectric sensor 542A. Then, a lower guide plate 518 is rotated and moved to a horizontal position direction, and when the shield plate 538 is detected by the photoelectric sensor 542A, the motor 530 is stopped. The motor 530 is provided with a self- braking function, and owing to engagemant between the helical gear 528 and the worm gear 534, the lower guide plate 518 is held at a horizontal position without rotating by its own weight. Thus, a holding means such as a stopper, etc., need not be used, and configuration can be simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a plate inspection device. More specifically, the present invention relates to an apparatus for creating a test plate using a photosensitive material to be used when checking the quality of color printed matter.

[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, in the surface plate section where the photosensitive material is positioned in the plate inspection device, the photosensitive material that has been exposed is transferred to the processor section where processing such as development is carried out in a short time, which reduces the processing time. preferable. However, in the processor section, the photosensitive material is transported at a constant transport speed and processed by being immersed in a processing liquid such as a developer for a predetermined period of time, so it is difficult to increase the transport speed. For this reason, two pairs of rollers are arranged at a predetermined interval in the transfer section to sandwich and convey the photosensitive material.
The rotational speed of the pair of rollers on the surface plate side is high, and the rotational speed of the pair of rollers on the processor side is low, corresponding to the conveyance speed of the processor. Further, a guide member is disposed between the two roller pairs. This guide member has a first position for guiding the transfer of the leading end of the photosensitive material from the surface plate section to the processor section below the photosensitive material conveyance path formed approximately horizontally in the transfer section; It is possible to rotate between a second position, which is further away from the transport path than the first position, and a second position where the lower side of the photosensitive material is opened. The guide member is stopped and held at a first position when the leading end of the photosensitive material is delivered from the surface plate part to the processor part, and is rotated by the motor and stopped at the second position after the leading end of the photosensitive material is delivered. Ru. This results in
After the tip of the photosensitive material is delivered, the weight of the photosensitive material causes 2
A loop is formed between each pair of rollers, and even after the rotational speed of the roller pair on the processor side becomes low, the difference in rotational speed between the roller pairs 2&u is absorbed and the photosensitive material is transferred.

(Problem to be Solved by the Invention) However, the holding of the guide member in the stopped state at the first position and the second position cannot be achieved by using stoppers arranged corresponding to each of the first position and the second position. This was done by holding means such as For this reason, the configuration of the delivery section becomes complicated, and the delivery section cannot be made compact.

The present invention has been made in consideration of the above-mentioned facts, and an object thereof is to provide a plate inspection device that can simplify the configuration of the delivery section.

[Means to solve the problem]

In order to achieve the above object, the plate inspection device according to the present invention includes a surface plate section on which a photosensitive material and an original film are conveyed and positioned, and a surface plate section that is arranged correspondingly to the surface plate section and transfers the image of the original film to the photosensitive material. an exposure section that exposes to light, a processor section that develops the exposed photosensitive material, and a delivery section that transfers the photosensitive material from the surface plate section to the processor section;
A first plate inspection device comprising: a first plate guiding the transfer of the leading end of the photosensitive material from the surface plate section to the processor section below the photosensitive material conveyance path formed substantially horizontally within the transfer section; and a second position that is spaced apart from the conveying path from the first position and opens the lower side of the conveying path for the photosensitive material, and a worm gear that rotates by the driving force of the driving means. a transmission means for transmitting the rotational force of the worm gear to the guide member; and a transmission means for transmitting the rotational force of the worm gear to the guide member;
The guide member is characterized by comprising a control means for controlling the driving means so as to stop the guide member at the position and move the guide member to a second position after the leading end of the photosensitive material is transferred.

[Effect]

In the present invention, when transferring the leading end of the photosensitive material from the surface plate section to the processor section, the guide member is stopped at the first position below the photosensitive material transport path. The guide member is configured to transmit the rotational force of the worm gear rotated by the driving force of the driving means. The worm gear is not rotated by the weight of the guide means, and can maintain the stopped state of the guide means. Therefore, there is no need to use a holding means such as a stopper to maintain the stopped state of the guide means, so the configuration of the delivery section can be simplified and the delivery section can be made more compact. After the leading end of the photosensitive material is delivered, the guide member is rotated to a second position which is further away from the conveying path than the first position and opens the lower side of the photosensitive material conveying path. As a result, the photosensitive material forms a loop due to its own weight within the transfer section, and can be smoothly transferred from the surface plate section to the processor section.

〔Effect of the invention〕

As explained above, in the present invention, since the rotational force of the worm gear rotated by the driving force of the driving means is transmitted to the guide member, an excellent effect can be obtained in that the configuration of the transfer section can be simplified.

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 extending from the outer surface 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 has a circular hole 2 provided in the support plate 232.
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.

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.
A plurality of units are arranged according to the number of types of width dimensions. In this embodiment, the number of photosensitive materials 14 used in the width direction is three types, and the reference position of the photosensitive material 14 (one end side in the width direction is constant regardless of which photosensitive material 14) and the other side of each photosensitive material 14 are used. 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.

The suction ffi base 256 has two small diameter suction cups 264 (
15 to 20 mm in diameter) are arranged in parallel. Therefore, the suction force of the photosensitive material 14 by one suction cup unit 254 is not concentrated in one place, but can be suctioned over a relatively wide range. For this reason, for example, in order to obtain suction force with a single suction cup, the suction cup 26 of this embodiment
4 only requires half that amount of gravity.

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.

As shown in FIG. 5(A), a base plate 270 is provided on the lower surface side of the photosensitive material 14, and the connecting shaft 230
This is done by rotating the support plate 232 by half a turn, moving the support plate 232 downward, and sandwiching the photosensitive material 14 between the suction cup 264 and the base plate 270. At this time, the sucker base 256
is moved toward the support plate 232 against the biasing force of the compression coil spring 262, so that the clamping force of the photosensitive material 14 between the suction cup 264 and the base plate 270 is maintained almost constant. ing'.

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

When the photosensitive material 14 is transported to a predetermined position by the moving member 202, the connecting shaft 230 rotates half a rotation, so that the photosensitive material 14 is placed on the surface plate 302, and the electromagnetic valve 268 is activated to release the adsorption. As a result, the moving member 202 and the photosensitive material 14 are separated.

As shown in FIG. 5(A) and FIG. 10, the moving member 2
02, brackets 272 are attached to the inner sides of the pair of leg plates 204, respectively. Bracket 2
72 is provided with an elongated hole 272A in the vertical direction, through which a rotating shaft 274A of a squeeze roller 274 for photosensitive material is passed. This squeeze roller 274 for photosensitive material is placed on the surface plate 302 of the surface plate section 300 when its rotating shaft 274A is located at the lower end of the elongated hole 272A. Further, a cam plate 276 is attached to the base plate 270 in correspondence with the rotating shaft 274A of the squeeze roller 274 for photosensitive material.

Therefore, when the moving member 202 is stopped at the original position, the photosensitive material squeeze roller 274 climbs onto the cam plate 276 to form a gap with the base plate 270. .

That is, the photosensitive material squeeze roller 274 is configured not to interfere with the photosensitive material 14 conveyed from the magazine loading section 100.

When the moving member 202 reciprocates, the squeeze roller 274 for photosensitive material is moved without rotating while being placed on the photosensitive material 14 on the outward path, and the squeeze roller 274 for photosensitive material 14 is moved on the return path without rotating.
4. It moves while rotating on top. This return rotational movement squeezes and expels the air between the photosensitive material 14 and the surface plate 302.

As shown in FIG. 15, the surface plate main body 306 is provided with a plurality of holes 308 passing through the front and back surfaces. The holes 308 are provided corresponding to each pattern formed on the pattern forming plate 310, which is an intermediate layer.

The pattern forming plate 310 is made of a sponge having closed cells, and predetermined patterns 310A-H are punched out using a die, as shown in FIG. pattern 3
10A to 10H are of eight sizes, and the combination of these corresponds to the eight types of sizes of the photosensitive materials 14.

As shown in FIG. 14, the pattern forming plate 31O is
It is sandwiched between the surface plate main body 306 and the bottom base plate 312. The base plate 312 is provided with a plurality of circular holes 314 on its periphery, and the pattern forming plate 310 is also provided with a coaxial circular hole 316. This circular hole 316 has a larger diameter than the circular hole 314 of the base plate 312, and a ring-shaped spacer 31B is inserted therein. Spacer 3
In this embodiment, the axial dimension of the pattern forming plate 18 is 2 mm, which is slightly smaller than the thickness of the pattern forming plate 310.

In addition, female threads 306A are formed in the surface plate body 306 corresponding to these circular holes 314.316, and
It is said to be coaxial with 16. Here, insert the screw 320 into the circular hole 3.
14.316 and screwed together with the female screw 306A, the pattern forming plate 310 is held and fixed between the surface plate main body 306 and the base plate 312.

Here, since the pattern forming plate 310 is a soft member,
It will be crushed according to the tightening torque of the screw 320, but since the spacer 318 is provided in the circular hole 316, it will be crushed to the axial dimension (2*-) of this spacer 318, and then the spacer Surface plate body 30 by 318
6 and the base plate 312 is maintained constant. Therefore, a plurality of spaces partitioned by the pattern forming plate 310 are independently formed between the surface plate main body 306 and the base plate 312.

The base plate 312 corresponds to each partitioned pattern space.
The female screw hole 312A is penetrated through the piping plug 322.
A male screw 322A is screwed together. Piping plug 322
are each connected to one end of a tube 324, and the other end is connected to a solenoid valve 326 (see FIG. 11) connected to a control device 800. The solenoid valve 326 is the plate inspection device 10

A female screw hole 312B communicating with 32 is formed, and a piping plug 334 is screwed into the hole 312B. Like the other piping plugs 322 described above, this piping plug 334 is also connected to the suction device 21B by a tube 324 via a magnetic valve 336. As a result, when this solenoid valve 336 is opened,
The hollow portion of the through hole 332 becomes a negative pressure, and air is sucked in from the groove 328 provided in the surface plate body 306. Above the groove 328 is a transparent overlay sheet 708 (both second and second) which is larger than the photosensitive material 14 and original film 16.
By adsorbing this overlay sheet 708 through the groove 328, the photosensitive material 14 and original film 16 are placed on the surface plate main body 3.

This allows the support plate 406 to move along the rail 404 in the longitudinal direction of the rail 404. Although three rollers 416A to 416C are provided in this embodiment, the number of rollers is not limited to this.

Further, a bracket 418 is attached to the bracket 410 in proximity to the roller 416A, and this bracket 418
The lower end portion of the leg plate 408 is bent at a right angle toward the outside of the leg plate 408 to form an extending portion 418A. A roller 416D is pivotally supported on this extension portion 418A via a shaft 420 (see FIG. 20), and is in contact with the outside of the rail 404. Therefore, the support plate 406 is supported on three sides with respect to the rail 404, and is slid smoothly without wobbling when moving along the rail 404.

In the support plate 406, a connecting bracket 422 is attached to the inside of each leg plate 408, and the connecting bracket 422 is fixed via a screw 428 to a part of an endless chain 426 wound around a pair of sprockets 424. There is.

The sprockets 424 are disposed near both ends of the rail 404 in the longitudinal direction, so that the sprockets 424

It has become. The motor 436 is rotated in forward and reverse directions, and the reciprocating rotation of the motor 436 causes the support plate 406 to reciprocate along the rail 404 from the original position on the front side of the plate inspection device 10 to the back side. It is the composition.

A long hole 408A is formed in each leg plate 408. Both ends of the rotating shaft 438A of the squeeze roller 438 are inserted into the elongated hole 408A. The squeeze roller 438 has its axially intermediate portion covered with a felt-like soft member 438B, and is moved on the surface plate 302 while being rotated by its own weight as the support plate 406 moves.

As shown in FIG. 21, one end of a hanging bracket 440 is locked at two points equally distributed from the center position in the axial direction of the squeeze roller 438 toward both ends. The other end of the hanging bracket 440 extends toward the surface of the upper support plate 406. The other end of the hanging bracket 440 is provided with a hole 440A, and a solenoid 440 disposed on the support plate 406 is provided with a hole 440A.
It is fixed to the actuator 442A via screws. The solenoid 442 activates the actuator 44 when energized.

Of the 6 round trips, this was the return trip.

As shown in FIG. 20, cam brackets 444 are attached to both ends of the rail 404 in the longitudinal direction of the plate inspection device 10 so as to interfere with the movement path of the squeeze roller 438, respectively. The cam bracket 444 has a high portion 444A formed to provide a gap between the squeeze roller 438 and the surface plate 302.
The height of the surface plate 302 and the high portion 444A are continuous by a slope portion 444B. Therefore, when the support plate 406 is in its original position, the solenoid 44
Even if the power supply 2 is not energized, a gap will be formed between the base plate 302 and the base plate 302 . Also, at the turning point on the back side of the device, the squeeze roller 438 is configured to climb up onto the cam bracket 444.

As shown in FIG. 19, the support plate 406 and casing 446 are separately attached to the chain 426 on the bracket 42.

A box-shaped casing 446 constituting the light source unit 402 may be fixed to one end of the support plate 406 in the width direction via a connecting member (not shown), and supported by the rail 404 by four rollers 447. 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 shutter 452 is attached to the casing 446 in correspondence with the slit hole 446A. A lens (
For example, a SELFOC lens) 446B has a bracket 447A on one side, and a bracket 447B and a screw 45 on the other side.
It is crimped and fixed with a resin plate 449 via 1A. Brackets 447A and 447B are attached to casing 446 with screw 4.
It is fixed by 51B and 451C.

The opening/closing shutter 452 is configured to be moved in the width direction by a guide rail 454. As shown in FIG. 23, one end in the width direction of the opening/closing shutter 452 is bent at a substantially right angle, and the actuator 456A of the solenoid 456
It is connected via a shaft 460 to a bracket 458 attached to the.

Here, when the solenoid 456 is energized, the actuator 456A is retracted, moves the shutter 452 in the width direction (direction of arrow A in FIG. 23), and moves the slit hole 446A.
I'm trying to make it open.

Further, a bracket 462 extending in the width direction is attached to the lower end of the opening/closing shutter 452, and one end of a tension coil spring 464 is latched thereto. The other end of this tension coil spring 464 is locked to the casing 446.

As a result, when the solenoid 456 is de-energized, the actuator 456A is pulled out by the biasing force of the tension coil spring 464, and the opening/closing shutter 452 causes the slit hole 44' to be pulled out.
6A is closed.

A motor 468 is attached to one side of the casing 446 , and a drive shaft 470 is coaxially attached to the rotating shaft of the motor 468 and passes through both sides of the casing 446 . Gears 47 are provided on the drive shaft 470 on the outside of the side surface of the casing 446.

is moved along the width direction of the slit hole 446A.

A pair of racks 474 are formed at both ends of the filter support plate 476. Six slit holes 476A are formed in the filter support plate 476, and a filter sheet 478 is arranged therein. This filter sheet 47
8 is provided with six slit holes 478A, and a filter 480 is attached to each of them. Both longitudinal ends of the filter sheet 478 are connected to the filter support plate 47.
It is fixed by a plate 482 attached to the top surface of 6. The filter support plate 476 is attached to the casing 4
46 is housed in a groove 484A of a plate 484 attached to the plate 484. A fixing plate 486 is attached to correspond to this groove 484A, so that the filter support plate 476 is connected to the plate 484 fixing plate 48.
It is clamped and fixed by 6.

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(
Red) filter, negative and positive G (green) filter, B (blue) filter, BK (black)
Six colors of filters are arranged side by side. 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 .

It is adapted to be moved together with the casing 446.

Six photoelectric sensors 4 are installed corresponding to the movement locus of the shielding plate 488.
90 is arranged, and the shielding plate 488 covers this photoelectric sensor 490.
It passes between the light emitting part and the light receiving part. These photoelectric sensors 490 are each controlled by a control device 800.
connected to.

The interval dimension of the six photoelectric sensors 490 is the same as that of the filter 4.
It matches the pasting interval dimension of 80.

Therefore, by selecting the detection signal of any one of the six photoelectric sensors 490 and controlling the drive of the motor 468 using this signal, the selected filter 480 can be made to correspond to the slit hole 446A.

Sensitivity S 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. Twenty roller pairs 504 have one of them as a drive roller 504A that rotates at a speed V (V=constant) under the driving force of a motor (not shown), and the photosensitive material 14 is sandwiched between it and the other driven roller 504B. As a result, a conveying force is applied 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 rotation shafts B and 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 the actuator 512A of the solenoid 512 via a hanging bracket 51O. 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. Twenty roller pairs 514 also include 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 1. The rotational speed of the second drive roller 514A can be changed in three stages, the highest speed is the same as the speed of the drive roller 514A, and the latter two speeds are slower than this rotational speed (VFI, V PAP□), here, VFILII
corresponds to the transport speed in the processor unit 600 when the photosensitive material 14 is a film, and V PAP! 1
is the processor section 600 when the photosensitive material is paper.
The setting corresponds to the transport speed at

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 51B 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. This helical gear 528 is connected to the rotating shaft 53 of the motor 530.
It meshes with a worm gear 534 attached to 2. The motor 530 has a self-braking function, and even when the motor 530 is not energized, the worm gear 53
4 is not rotated.

Here, the lower guide plate 518 is supported by the rotating shaft 526 via the swing base 524.
Since the helical gear 528 meshes with the worm gear 534, the lower guide Fi51B rotates around the rotating shaft 526 under its own weight.
Rotation around the center is prevented.

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 conveyed 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 changed to a low speed (
VFILH or VIIPI! R). At the same time or a little earlier, the motor 530 is driven to rotate the lower guide plate 518 in the vertical direction. Therefore, slack in the photosensitive material 14 due to the difference in conveyance speed between the upstream and downstream roller pairs 514 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 roller pair 504.

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. For this reason, in this embodiment, the rotational speed of the roller pair 604 on the processor section 600 side is rotated slightly faster than the rotational speed of the downstream roller pair 514, and the photosensitive material 14 is held under a predetermined tension. It is being transported.

Guide shafts 718 parallel to each other are attached via brackets 716 to the front side and back side of the plate inspection making device 10 inside the large M26. This guide shaft 718 is coaxial with a pair of guide shafts 720 provided in the exposure section 400 when the large 124 is in the closed state.

As shown in FIG. 28, one end of the guide shaft 720 on the exposure section 400 side is fixed to a side plate 722 provided between it and the film loading section 700 via a bracket 724. This bracket 724 has a tongue piece 724A having an arcuate surface having the same diameter as the outer periphery of the guide shaft 720 at its tip.
It is fixed to 24A. The other end of the guide shaft 720 is fixed to a bracket (not shown) fixed to the plate inspection device 10.

A rectangular hole 726 is provided in the side plate 722 between the exposure section 400 and the film loading section 700, allowing the exposure section 400 and the film loading section 700 to communicate with each other. This rectangular hole 7
26 is a support base 72 on which the original film 16 is loaded.
It serves as a communication passage for 8.

As shown in FIG. 29, a lid 730 for closing the rectangular hole 726 is disposed on the film loading section 700 side of the side plate 722 in which the rectangular hole 726 is formed. The W body 730 is dish-shaped and has an opening facing the rectangular hole 726. One end of a bracket 732 is fixed to the back of the lid 730. The other end of the bracket 732 is connected to a shaft 7 provided longitudinally below the rectangular hole 726.
34 Hebisufu 35 is fixed. shaft 7
A torsion coil spring 736 is attached to 34, and one end of this torsion coil spring 736 is connected to the bracket 73.
2, and the other end is fixed to the lower side plate 722 of the rectangular hole 726.
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 mutually parallel leg plates 740A of the bracket 740.

A roller 744 is supported on this shaft 742 .

As shown in FIG. 28, the support base 728 has a frame shape and has a pair of shafts 746 attached at three locations on the outer side surface facing the guide shaft 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 746.

Leg plates 750A parallel to each other are formed on the bracket 750, and each leg plate 750A has a coaxial circular hole 75.
0B is provided. This circular hole 750B has a shaft 752.
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 at each location) and is slidable in the axial direction of the guide shaft 718, 720. has been done.

The guide shaft 720 is a guide shaft of the large lid 24) 7
18, their ends 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, It is configured to be supported by the guide shaft 718 of the large 124. Here, when the rollers 748 and 754 are detached from the guide shaft 720, the support base 728 is attached to the guide shaft 720 at the other four locations.
It is gaining support. Therefore, the support base 7
28 are respectively supported by guide shafts 720 or 718 at both widthwise ends of the support base during movement,
And it is supported at at least two or more locations along the moving 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.

Here, when the support base 728 is moved from the exposure section 400 to the film loading section 700 as shown in FIG. This roller 74
4, a rotational force about the shaft 734 in the opening direction of the rectangular hole 726 is applied to the lid body 730. Therefore, as the support base 728 is further moved, the roller 744 is rolled from the side surface to the bottom surface of the support base 72B, and the lid body 730 is rotated against the biasing force of the torsion coil spring 736. In other words, 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 having three edges bent at approximately right angles, excluding the upper side. The flange portion 756B faces 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 700, 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. The 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 this extended portion is locked to a portion of the chain 766 via a screw. Chain 766,
Plate inspection device 10 for both axial ends of the guide shaft 720
is wound around a pair of sprockets 770 attached via a bracket 768 (only the right side shown in FIG. 28).
forming 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 on the movement trajectory of this shielding vi790, there are two
photoelectric sensors 792 are arranged. Photoelectric sensor 7
92 is attached near both ends in the axial direction of the guide rail 720 in the plate inspection making device 10, so that the shielding plate 790 passes between the light projecting section and the light receiving section. This photoelectric sensor 792 controls the amount of movement of the support plate 728 by the motor 776, and
It has the role of positioning the film to a predetermined position in the exposure section 400 and the film loading section 700. Note that once the support plate 728 is positioned at a predetermined position in the film loading section 700 and the closing member 756 and the light shielding members 758 and 762 are in a state where light is prevented from entering the exposure section 400 from the rectangular hole 726. Since the small lug 704 is unlocked, the small lid 704 can be opened and the original film 16 can be loaded through the rectangular hole 702. When the support plate 728 is in a position straddling the exposure section 400 and the lens loading section 700, the small lid 704 is not unlocked and light is prevented from entering the exposure section 400 from the rectangular hole 702. .

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 782 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 sheet 708 is attached to the. The area of this overlay sheet 708 is approximately the same as the opening area of the support base 728, and
4, they are 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 knock pin 788A on one end side of the size plate 788 has a protrusion with an oval cross section, and the other two knock pins 788A have 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.

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, and the circular hole 16A of the original film 16 is inserted into the slot 788A.
The loading is completed by inserting the original film 16 onto the overlay sheet 708 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.

The control device 800 is the intermediate base 20 of the plate inspection device 10.
, that is, below the surface plate section 300 .

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 81O, and a bus 812 such as a data bus or a control bus that connects these.

The input/output hoard 810 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.

In the surface plate section 300, photoelectric sensors 354A to 354C are connected, and a solenoid valve 326 is connected through a driver 822, a solenoid valve 336 is connected through a driver 824, and a motor 348 is connected through a driver 826, respectively.

In the exposure section 400, a photoelectric sensor 490 is connected, and a motor 436 and a driver 83 are connected via a driver 828.
0, a solenoid 442 is connected to the driver 832, a fluorescent lamp socket 450 is connected to the driver 832, a solenoid 456 is connected to the driver 834, and a motor 468 is connected to the driver 836.

In the photosensitive material delivery section 500, a photoelectric sensor 542A
, B and the photoelectric sensor 544 are connected, and the driver 838
The solenoid 512 and the motor 530 are connected via a driver 840 and a solenoid 512, respectively.

In the processor section 600, a fan 648 is connected via a driver 842, and a heater 650 is connected via a driver 844.
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
In step 002, initial settings for each part are performed (see the 34th period setting routine). In the magazine loading section 100, the magazine 102 is loaded into the magazine loading port 106. Here, a light reflective sheet 110 is attached to the magazine 102,
Light from the photoelectric sensor 114 returns to the photoelectric sensor 114 again through a rectangular hole 112 provided in the back wall 106A of the magazine loading port 106. The number and position of the light reflecting sheets 110 to be pasted are determined for each size and type of 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 the top of the surface plate 302 and placed onto the base plate 270 with a slight gap. Furthermore, at this position, the photosensitive material squeeze roller 274 climbs up onto the cam plate 276, so that a gap is also created between the base plate 270 and the photosensitive material squeeze roller 274, 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 it is not detected, the motor 348 is driven, and the rack 3 is driven by the driving force of the motor 348 via 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 base plate 270.

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 unit 500, in step 1108, it is determined whether or not the shielding plate 538 is detected by the photoelectric sensor 542A. If not, the motor 530
is driven, the worm gear 534 attached to the rotating shaft 532 is rotated, and the helical gear 528 is rotated. Due to the rotation of this helical gear 528, the rotation shaft 526
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 1110, 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. By driving this motor 776, the sprocket 770 is rotated, and the chain 770 is rotated.
66 is driven. Since the support base 72B 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 1O as the chain 766 is driven. When the support base 728 moves, it presses the roller 748 attached to the lid 730 and twists the lid 730 so that the coil spring 7
36 and rotates around the shaft 734. 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 shield 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 base 728 is positioned in the film loading section 700. Note that in this state, the support base 72
Since the closing member 756 of No. 8 closes the rectangular hole 726 via the light shielding members 758 and 762, it is possible to prevent light from entering the exposure section 400 from the film loading section 700.

Further, the overlay sheet 708 is held in a downward position of the gear 780A by driving the motor 782.

A size plate 788 corresponding to the applied original film 16 is magnetically attached to the positioning plate 786. The document film 16 is provided with a circular hole 16A, and is inserted into the knock hinge 788A provided on the size plate 788.
Loading of the original film 16 is completed by placing the original film 16 on the overlay sheet 708.

When the initial settings of each part are completed, the process moves to step 1004 of the main routine, where the initial setting of the photosensitive material
(see figure) is performed.

First, the photosensitive material 14 is pulled out from the outlet 10 of the magazine 102, transported 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 inserted into the gap between the base plate 270 and the suction cup 264. Here, the photosensitive material squeeze roller 274 climbs up onto the cam plate 276, and the rotating shaft 274A is inserted into the elongated hole 276.
Since they are arranged toward the upper end of A, the photosensitive material 14 and the photosensitive material squeeze roller 274 do not interfere with each other.

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, when the motor 224 is driven in step 1206, the cam 228 rotates by half a rotation via the gear box 226. Due to this rotation of the cam 228, the connecting shaft 230 is
28 and lowers the bearing 234. Bearings 234 are plats 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 the movable member 2
02 through the fixed base 238 while being guided by the shaft 244, 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 the suction cup 264 and the base plate 270
As a result, the photosensitive material 14 is sandwiched. 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 140, and the suction cup units 254 are installed 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 1212, with the photosensitive material 14 being sucked by the suction cup 264, the motor 21B is driven to move the moving member 202 to the right in FIG. 2 along the rail 210. At this time, the conveying speed of the photosensitive material 14 of the roller pair 104 is made to match the moving speed of the moving member 202, and the photosensitive material 14 is conveyed while maintaining a constant tension. Further, the squeeze roller 274 for photosensitive material is lowered from the cam plate 276, and the surface plate 3
02 via the photosensitive material 14. For this reason,
The moving member 202 is not rotated on the photosensitive material 14.
being dragged and moved.

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 (step 121).
6), actuate the cutter 116 (step 121B),
The photosensitive material 14 is cut. Thereby, it is possible to separate the photosensitive material 14 of a predetermined size from the roll-shaped photosensitive material 14.

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).

When the leading end of the photosensitive material 14 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 a pattern forming plate 310 is sandwiched between a surface plate main body 306 and a 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. . Note that the suction of the photosensitive material 14 by the fixed fi 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 it is clamped between the surface plate body 306 and the base plate 312 with the screws 320, the axial dimension of the spacer 318 (2
vs), the pattern can be reliably formed. 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 forefront and then returns to the initial position along the rail 21O (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 3.degree.2 is guided by this slide shaft 364, the surface plate 302 is moved perpendicularly while maintaining a state parallel to the intermediate base 2o by the drive of the motor 348.

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

Next, in step 1008 of the main routine, original film transport control (number M in Figure 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).

Support base 728 connects rollers 748, 754 to guide shaft 718 when located in film loading station 700.
Supported through. This guide shaft 718 is
The guide shaft of the exposure section 400 on the side where the rectangular hole 726 is provided? It is separated from 20. However, roller 74
8.754 are provided at six locations (three locations on each side) on the support base 728, and even if the roller 748.754 at the tip in the moving direction separates from the guide shaft 718 due to movement of the support base 728, it is supported at the other four locations. Since the base is supported on the guide shaft 718, this tip roller 748.
854 can smoothly transition from guide shaft 718 to guide shaft 720. In addition, the intermediate roller 748
．． 754 from the guide shaft 718 to the guide shaft 720
When moving, the rollers 748, 754 at the leading end are supported by the guide shaft 720, and the rollers 748, 754 at the rear end are supported by the guide shaft 718, so that the movement can be made smoothly. Further, in the trailing end rollers 748, 754, the leading and middle rollers 748, 754 are supported by the guide shirt l-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 coil spring 736 torsioned 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, an exposure standby system W (see FIG. 38) is executed.

First, in step 1500, the motor 782 attached to the support base 728 is driven, and the chain 784
drive. As a result, the overlay sheet 708 becomes
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 sheet 708 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, the suction action resides 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 allowing the surface plate 302 and the overlay sheet 708 to sandwich and hold the photosensitive material 14 and the original film 16.

When the groove 328 has been attracted to the overlay 708 for a predetermined period of time (step 1510), the motor 436 of the exposure unit 400 starts driving in 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.
and is placed on the surface plate 302 via the overlay sheet 70B. As the support plate 406 moves along the rail 404, the squeeze roller 438 rotates and moves on the overlay sheet 708. Further, the photosensitive material 14, the original film 16, and the overlay sheet 708 are brought into close contact with the surface plate 302 by suction. As a result, the air between the overlay sheet 708 and the surface plate 302 is pushed out, and the photosensitive material 14 and original film 16 are placed on the surface plate 302.
and can be brought into close contact with each other completely.

When the support plate 406 reaches the rear end of the device, the squeeze roller 43B is gradually separated from the overlay sheet 708 by the cam bracket 444. Support plate 4
06 is stopped, the solenoid 442 is energized in step 1514, and the actuator 442 Ai
<Retract, which raises and holds the squeeze roller 438 via the suspension bracket 440.

Here, the squeeze roller 438 is connected to the cam bracket 44
4, 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, an exposure process m (see FIG. 39) is performed.

First, in step 1600, by driving the motor 468, filters (B, , G, R , one of the ink) through the slit hole 476
Place it on A.

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, the image on the original film 16 is printed onto the photosensitive material 14 by moving the support plate 406 to its original position (step 1604).

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
By driving the motor 348 (step 1700), the photoelectric sensor 354B is lowered to a position where the shielding plate 356 is detected (steps 1702 and 1704), and then step 1
At 706, support base 728 of film loading section 700
A motor 782 attached to the motor 782 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 when the overlay sheet 70B is moved, the solenoid valve 336 is closed, and the adsorption of the overlay sheet 70B onto the surface plate 302 is stopped. When the placement of the original film 16 on the overlay sheet 708 is completed,
Proceeding to step 1708, the support base 728 is driven by the motor 776 to be moved to the film loading section 700 and supported on the guide shaft 718. Here, the small lid 70
4 is unlocked, grasp the handle 706 of the small film 704 to open the small lid 704, replace it with the next color-separated original film 16, and repeat the exposure control a predetermined number of times (step 1016 of the main routine). ).

When the exposure process is completed, the support base 728 is moved to the film loading section 700 and is placed on standby while being supported by the guide shaft 718, and is then moved to step 1 of the main routine.
The process moves from step 016 to step 1018, and exposed photosensitive material transport control 1 (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.
At step 4, the photosensitive material 14 is suctioned and the suction of the photosensitive material 14 by the surface plate 302 is released (step 1814), and the support plate 232 is raised 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 302 of the photosensitive material 14 is closed.
Adsorption to the top is 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), and temporarily stops the rotation of the drive roller 504A (
Step 1824), and the solenoid 512 is deactivated (Step 1B26).

As a result, the driven roller 504B becomes the driving roller 504A.
Next, in step 1828, the suction of the photosensitive material 14 by the suction cup 264 is released, and the moving member 202 is moved toward the rail 2.
10 and return to the original position.

In the next step 1830, the drive roller 504A is restarted to rotate at speed 2 to transfer the photosensitive material 14 to the processor section 60.
Convey in the 0 direction.

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, in step 1902, when the tip of the photosensitive material 14 reaches the top of the photoelectric sensor 544, it is detected by the photoelectric sensor 544, and the motor 530 is driven (step 1
904).

By driving this motor 530, the helical gear 528 is rotated via the worm gear 534, and the rotation shaft 526 is rotated to the second position.
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 1906, the conveyance speed of the roller pair 514 is reduced to the same speed (V□ or V□2□) as that of the processor section 600, which is slower than the speed ■. This results in
Photosensitive material 14 between roller pair 504 and roller pair 514
The second 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 transferred to the tray 5 while being held by the roller pair 514.
It is accommodated in 46.

The photosensitive material 14 is transferred to the roller pair 604 of the processor section 600.
sandwiched between. The conveyance speed of this 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 a pair of rollers 624 of a processing rack 622 and a guide plate 626, and conveyed in a substantially U-shape. They are transported and processed in the order of washing 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.
