Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a plate inspection creating apparatus. More particularly, the present invention relates to an apparatus for preparing a plate using a photosensitive material for use in checking the quality of a color print.

[Conventional technology]

When printing a large amount of color on a printing machine, for example, printing a color advertisement (so-called insertion advertisement) attached to a newspaper or the like, use a plate inspection creating device (color proof creating device) before printing on the printing machine. Prior to actual printing, a check is made in advance. The plate inspection apparatus includes a platen section on which a photosensitive material and a document film developed and processed after disassembly and exposure are conveyed and positioned, and an exposure apparatus disposed on the platen section to expose an image of the document film to the photosensitive material. Unit, a processor for developing the exposed photosensitive material, and a delivery unit for delivering the photosensitive material from the platen to the processor. A manuscript film is prepared for each color separation component and is made into one set of a plurality of sheets. The plate inspection making device applies a plurality of manuscript films to one photosensitive material positioned on the platen by the exposure unit. Are sequentially exposed. The exposed photosensitive material is conveyed from the surface plate section to the processor section via the transfer section, where it is subjected to development, bleach-fixing, washing and drying. With the processed photosensitive material, a check can be made before the actual printing is performed. Thus, for example, when there is a problem with the color condition, image position, character error, or the like of the photosensitive material, it is possible to correct the original film and the like before printing a large amount by a printing machine.

By the way, when the photosensitive material is positioned on the surface plate in the plate making apparatus, simply by placing the photosensitive material on the surface plate, if the photosensitive material is curled, the focus is deviated at the time of exposure, or the exposure unevenness occurs. Therefore, a plurality of suction holes are provided in the surface plate to absorb the photosensitive material. Thereby, the photosensitive material can be brought into close contact with the surface plate.

[Problems to be solved by the invention]

However, if the peripheral portion of the photosensitive material is curled due to ambient environmental temperature, humidity, or the like, a large gap is generated when the photosensitive material is placed on the surface plate, and the photosensitive material may not be reliably attracted. Further, air bubbles may be trapped between the photosensitive material and the surface plate. Exposure in such a state affects a finished image.

For this reason, a mechanism for squeezing the photosensitive material after placing it on the surface plate may be provided. However, simply providing the squeeze mechanism undesirably causes the squeeze mechanism to interfere with the photosensitive material transport path, which is not preferable. .

The present invention has been made in consideration of the above-described circumstances, and has as its object to provide a plate inspection apparatus capable of securely bringing a photosensitive material into close contact with a surface plate without obstructing a conveyance path of the photosensitive material.

[Means for solving the problem]

A squeeze roller for photosensitive material that is placed on the photosensitive material that has been placed and is driven to rotate to bring the photosensitive material into close contact with the surface plate; and a moving member that reciprocates the squeeze roller for photosensitive material from the original position along the surface plate. And a cam member that forms the photosensitive material transport path by separating the photosensitive material squeeze roller from the surface plate at the original position.

[Action]

According to the present invention, the photosensitive material is transported in order to place the photosensitive material at a predetermined position on the surface plate. At this time, the squeeze roller for photosensitive material is positioned at the original position by the moving member. In this state, the photosensitive material squeeze roller is separated from the surface plate by the cam member. Therefore, since the photosensitive material transport path is formed between the surface plate and the photosensitive material squeeze roller, there is no problem in transporting the photosensitive material.

After the photosensitive material is placed at a predetermined position on the surface plate, the squeeze roller for the photosensitive material is moved by the moving member while rotating on the photosensitive material to remove the curl of the peripheral edge of the photosensitive material, and is fixed to the photosensitive material. Air bubbles between the board and the board can be discharged.

As described above, according to the present invention, curls occurring in the photosensitive material and air bubbles between the photosensitive material and the surface plate can be removed without obstructing the transport path of the photosensitive material. Absent.

〔The invention's effect〕

That is, six colors of R (red) filter for both negative and positive, G (green) filter for negative and positive, B (blue) filter, and BK (Sumi) filter are arranged in parallel. Therefore, the negative and positive filters are adhered by one filter sheet 478, and the exchange according to the type of the photosensitive material (negative or positive) is not required.

A shield 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 490 are provided corresponding to the movement locus of the shielding plate 488, and the shielding plate 488 is provided.

The ends of tension coil springs (not shown) are locked to the rotating shafts of the driving roller 504A and the driven roller 504B, respectively, and are biased in the directions of contact with each other by the biasing force of the tension coil springs. .

Further, the driven roller 504B is connected to an actuator 512A of the solenoid 512 via a suspension bracket 510. The solenoid 512 draws the actuator 512A when energized, so that when energized, the drive roller 504A and the driven roller 504B are separated from each other against the urging force of the tension coil spring. In this state, the tip of the photosensitive material 14 adsorbed to the suction cup 264 is inserted into the gap between the driving roller 504A and the driven roller 504B.

Here, in the present embodiment, the drive roller 504A is rotated when the photosensitive material 14 is inserted into the gap, and is temporarily stopped after the insertion. Therefore, even if the tip of the photosensitive material 14 is slightly curled, the photosensitive material 14 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 Transport is prevented.

When the photosensitive material 14 is nipped by 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 the original position.

The roller pair 514 also includes a driving roller 514A, one of which rotates with the driving force of a motor (not shown), and a driven roller 514B which rotates in contact with the driving roller 514A. Here, the rotation speed of the drive roller 514A is:
The speed can be changed in three stages, and the maximum speed is the same as the speed V of the drive roller 504A, and the second two speeds are lower (V _FILM , V _PAPER ) than the rotation speed. Here, V _FILM corresponds to the transport speed in the processor unit 600 when the photosensitive material 14 is a film.
_PAPER is the processor unit when the photosensitive material is paper 6
It is set corresponding to the transport speed of 00.

A helical gear 528 is fixed to the rotating shaft 526. The helical gear 528 meshes with a worm gear 534 attached to the rotating shaft 532 of the motor 530. Motor 530
The worm gear 534 has a self-braking function, and is not rotated even when the motor 530 is not energized.

Here, the lower guide plate 518 is supported by a rotating shaft 526 via a swing base 524, but since the helical gear 528 meshes with the worm gear 534, the lower guide plate 518 is under its own weight. Rotation about the rotation shaft 526 is prevented.

A shield plate 538 extending in the radial direction of the rotary shaft 526 is attached to the rotary shaft 526, and two photoelectric sensors are attached to the side plate 506 via a bracket 540 in accordance with the movement trajectory of the shield plate 538. 542A and B are attached. Photoelectric sensor 542
A and B are connected to the control device 800, respectively. Each of the photoelectric sensors 542A and 542B includes a light projecting unit and a light receiving unit, and the shielding plate 538 enters between them.

One of the photoelectric sensors 542A and 542B has a lower guide plate 518.
Is located at a position where the shielding plate 538 blocks between the light emitting unit and the light receiving unit when is at the horizontal position (the solid line position in FIG. 24),
On the other hand, the lower guide plate 518 is in the vertical position (the position of the imaginary line in FIG. 24).
In this case, it is arranged at a position where the space between the light emitting unit and the light receiving unit is blocked by the shielding plate 538. Therefore, the control device 800 can control the driving of the motor 530 based on the output signals of the photoelectric sensors 542A and 542, and can position the lower guide plate 518 at the horizontal position and the vertical position.

Further downstream of the downstream roller pair 514, the photosensitive material 1
A photoelectric sensor 544 is provided below the fourth transport path.
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 end and the trailing end of the photosensitive material 14.

Here, the photosensitive material 1 sandwiched between the roller pair 504 on the upstream side
When 4 is conveyed, the downstream roller pair 514 is rotated at the same speed as the upstream roller pair 504. Therefore, the photosensitive material 14 sandwiched between the upstream and downstream roller pairs 504 and 514 is conveyed with a predetermined tension. Here, when the leading end of the photosensitive material 14 is detected by the photoelectric sensor 544, the rotation speed of the downstream roller pair 514 is reduced to a low speed (V _FILM or V _PAPER ) according to the type of the photosensitive material 1. Has become. At the same time or slightly earlier, the motor 530 is driven to rotate the lower guide plate 518 in the vertical position direction. For this reason, the slack of the photosensitive material 14 caused by the difference in the transport speed between the upstream side roller pair and the downstream side roller pair 514 can be formed in the lower space where the lower guide plate 518 does not exist.

A tray 546 is provided at the lowermost portion of the lower space, and serves as a storage portion when the rear end of the photosensitive material 14 comes off the upstream roller pair 504.

Sandwiched by 604. One of the roller pair 604 is a driving roller 604A that rotates by the driving force of a motor (not shown), and the other is a driven roller 604B that rotates by receiving a driving force from the driving roller 604A. The rotation speed of the driving roller 604A is substantially equal to the rotation speed (V _FILM or V _PAPER ) of the pair of downstream rollers 514 at low speed.

Here, as shown in FIG.
The drive roller 514A has a one-way clutch 606 interposed between its rotary shaft 514C and the rotary shaft 515 of the motor.
When the outer periphery of the roller is rotated at a speed higher than the rotation speed of the motor, the roller and the rotating shaft are relatively rotated. For this reason, in this embodiment, the rotation speed of the roller pair 604 of the processor unit 600
The photosensitive material 14 is transported in a state where a predetermined tension is generated by rotating the photosensitive material 14 at a speed slightly higher than the rotation speed of the 514.

A bracket 740 is attached, and a shaft 742 extends between the parallel leg plates 740A of the bracket 740. A roller 744 is supported by the shaft 742.

As shown in FIG. 28, the support base 728 has a pair of shafts 746 at three locations on the outer side surface facing the guide shaft 720 in a frame shape. The pair of shafts 746 are arranged at an interval in the up-down direction, and rollers 748 are supported by the respective shafts. The peripheral surfaces of these rollers 748 are configured to contact the outer peripheral upper and lower surfaces of the guide shaft 18 or the guide shaft 720.

Further, as shown in FIG. 30, between the pair of shafts 746,
A bracket 750 is provided. The bracket 750 has
Parallel leg plates 750A are formed, each leg plate 750A
Is provided with a coaxial circular hole 750B. This circular hole 750B
A shaft 752 is hung over the roller, and a roller 754 is supported at the intermediate portion. The peripheral surface of this roller 754 is
18 or the outer peripheral side surface of the guide shaft 720. Accordingly, the support base 728 is supported by the guide shaft 718 or the guide shaft 720 at a total of six places (three rollers 748 and 754 per place), and can be slid in the axial direction of the guide shafts 718 and 720. Have been.

Although the guide shaft 720 is separated from the guide shaft 718 of the large lid 24 at the ends thereof, the support base 728
When is moved toward the guide shaft 718 of the large lid 24, the rollers 748 and 754 on the distal end side in the moving direction are separated from the guide shaft 720 and are supported by the guide shaft 718 of the large lid 24. Here, guide shaft 72 of rollers 748, 754
At the time of departure from zero, the support base 728 is supported by the guide shaft 720 at the other four points. Therefore,
The support base 728 is supported by the guide shaft 720 or the guide shaft 718 at both ends in the width direction of the support base when moving, and is supported at at least two places along the moving direction. For this reason, the support base 728 passes through the rectangular hole 726, and the guide shaft 720 on the side of the exposure unit 400 and the film loading unit.
It is delivered smoothly to the guide shaft 718 on the 700 side.

Here, as shown in FIG. 29, when the support base 728 is moved from the exposure unit 400 to the film loading unit 700, the roller 744 of the lid 730 closing the rectangular hole 726 contacts the support base 728. The roller 744 applies a rotational force to the cover 730 in the opening direction of the rectangular hole 726 about the shaft 734 by the roller 744. Therefore, when the support base 728 is further moved, the roller 744 is rolled from the side surface to the bottom surface of the support base 728, and the lid 730 is rotated by the torsion coil spring 736.
It is designed to rotate against the urging force. That is, the opening of the lid 730 is automatically performed as the support base 728 moves.

At both ends in the longitudinal direction of the closing member 756, circular holes 756A are formed, and the guide shaft 720 penetrates.

The closing member 756 is formed with a flange portion 756B whose three edges except the upper side are bent at substantially right angles. The flange portion 756B faces the peripheral portion of the rectangular hole 726 when the support base 728 is moved to the film loading portion 700. A felt-shaped light-shielding member 758 (see FIG. 29) is attached to a peripheral portion of the rectangular hole 726. As the light shielding member 758, the female side of Magic Cloth (trade name) or the like can be applied. Further, a flange portion 760 bent at a substantially right angle is fixed to the upper side of the rectangular hole 726, and a tip end thereof is opposed to the upper piece of the closing member 756. A light blocking member 762 is attached to the upper piece of the closing member 756. As a result, the support base 728 pushes the lid 730 open and moves to the film loading section 700, and the closing member 756
Is in contact with the rectangular hole 726, light is prevented from entering the exposure unit 400 from the rectangular hole 726.

As shown in FIG. 28, a pair of brackets 764 are fixed to the back of the closing member 756 at both ends in the longitudinal direction. The bracket 764 extends at a substantially right angle in the direction in which the closing member 756 separates from the upper piece of the closing member 756, and further, its tip ends extend in the direction in which the closing members 756 separate from each other. The distal end of the extension is locked to a part of the chain 766 via a screw. The chain 766 is looped around a pair of sprockets 770 attached to the plate making device 10 at both ends in the axial direction of the guide shaft 720 via a bracket 768 (only the right side in FIG. 28 is shown). .

Hereinafter, the operation of the present embodiment will be described with reference to the control flowcharts of FIGS. 33 to 42.

First, in step 1000 of the main routine (FIG. 33), when the operation switch is turned on, initial setting of each part is performed in step 1002 (refer to FIG. 34 initial setting routine). In the magazine loading unit 100, the magazine 102 is loaded into the magazine loading port 106. Here, a light reflecting sheet 110 is attached to the magazine 102, and light from the photoelectric sensor 114 is supplied to the rectangular hole 1A provided in the wall surface 106A on the back side of the magazine loading port 106.
It returns to the photoelectric sensor 114 through 12 again. The number and position of the light reflecting sheets 110 to be stuck are determined for each size and type of the photosensitive material 14 housed in the magazine 102. Therefore, in the control device 800,
The size and type of the loaded photosensitive material 14 can be recognized based on the ON / OFF signal of the photoelectric sensor 114 (step 1100).

In the next step 1102, the photosensitive material transport unit 200
It is determined whether or not the moving member 202 is detected by the photoelectric sensor 220 on the left side of FIG.
Drive 218. The motor 218 drives the sprocket.
The chain 214 is driven via the 216, and the moving member 202 is moved along the rail 210 and stopped to the left in FIG.
In this position, the suction cup 264 deviates from the surface plate 302 and is disposed on the base plate 270 with a slight gap. In this position, the photosensitive material squeeze roller 274 climbs up to the cam plate 276, so that the base plate 270 and the photosensitive material squeeze roller 274
There is also a gap through which the photosensitive material 14 passes.

Next, in step 1104, the platen 302 of the platen unit 300 is arranged at the lowest position. 356 shielding plate by photoelectric sensor 354C
Is determined, and if not detected, the motor 348 is driven, and the rack 340 is moved downward by the driving force of the motor 348 via the gear box 350.
When the shielding plate 356 is disposed between the light emitting part and the light receiving part of the photoelectric sensor 354C, the platen is stopped, so that the surface plate 302 is stopped at a position flush with the base plate 270.

In the exposure unit 400, in step 1106, the support plate 406 bridged on the rail 404 is arranged on the front side of the plate inspection making apparatus 10. At this time, squeeze roller 438
The rotary shaft 438A is held in a state in which the rotary shaft 438A climbs up the cam bracket 444.

In step 1108, the photosensitive material delivery unit 500 determines whether the photoelectric sensor 542A has detected the shield plate 538. 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. This helical gear 5
The rotation of 28 rotates the rotating shaft 526 in the counterclockwise direction in FIG. Thereby, the lower guide plate 518 can be rotationally moved in the horizontal position (the position indicated by the solid line in FIG. 24). Here, when the lower guide plate 518 is in the horizontal position, the photoelectric sensor 542
The shield plate 538 is detected by A, and the driving of the motor 530 is stopped. This motor 530 has a self-braking function, and the lower guide plate 518 does not rotate clockwise in FIG. 24 by its own weight due to the engagement of the helical gear 528 and the worm gear 534. It is held in the horizontal position.

In the film loading section 700, in step 1110, the shielding plate 790 is detected by the photoelectric sensor 792 on the right side of FIG.
Is detected. This photoelectric sensor 79
If the shield plate 790 is not detected in step 2, the motor 776 is driven. By driving this motor 776, the sprocket 7
70 is rotated and the chain 766 is driven. A support base 728 is fixed to a part of the chain 766 via a bracket 768.
28 moves to the right in FIG. During the movement of the support base 728, the roller 748 attached to the lid 730 is pressed, and the lid 730 is rotated about the shaft 734 against the biasing force of the torsion coil spring 736. Therefore, the film can be moved to the film loading section 700 through the rectangular hole 726. Here, the drive of the motor 776 is stopped in a state where the shielding plate is detected by the photoelectric sensor 792 on the right side of FIG. As a result, the support base 728 is located at the film loading section 700. Note that, in this state, the closing member 756 of the support base 728 is
The rectangular hole 726 is closed via the
Light can be prevented from entering the exposure unit 400 from the outside.

Further, the overlay sheet 708 is held in a state where the overlay sheet 708 is arranged below the gear 780A by driving of the motor 782.

For the positioning plate 786, the applicable original film 1
Magnetically attach the size plate 788 according to 6. The original film 16 is provided with a circular hole 16A.The original film 16 is inserted into a notch pin 788A provided on the size plate 788, and the original film 16 is placed on the overlay sheet 708. Complete.

When the initial setting of each section is completed, the flow shifts to step 1004 of the main routine, where the initial transport control of the photosensitive material (see FIG. 35) is performed.

First, the photosensitive material 14 is pulled out from the outlet 108 of the magazine 102, is conveyed upward in FIG. 2, and in step 1200, the roller pair 104 is driven to wind around the roller pair 104, and the conveying direction is 90 °. Convert (step 1200).

The changed direction of the photosensitive material 14 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 on the cam plate 276, and the rotating shaft 274A is disposed at the upper end of the elongated hole 272A.
4 does not interfere.

After the photosensitive material 14 is conveyed by a predetermined amount such that the leading end thereof 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 half a turn via the gear box 226. This cam
By the rotation of 228, the connection shaft 230 rotates around the rotation center of the cam 228, and lowers the bearing 234. Bearing 234
Is fixed to the support plate 232 by the brackets 236A and 236B, so that the support plate 232 is lowered. Here, since the support plate 232 moves to the moving member 202 while being guided by the shaft 244 via the fixed base 238, the supporting plate 232 keeps a parallel state with the moving member 202 and descends without being relatively rotated.

With the lowering of the support plate 232, 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 sandwich the photosensitive material 14. In this state,
At 1208, the solenoid valve 268 communicating with the suction device 18 is opened, and the suction cup 2 is opened.
At 64, the photosensitive material 14 is adsorbed. Here, suction units are provided at four positions including a reference position in accordance with the size of the photosensitive material 14 in the width direction, and a suction device 18 is provided in accordance with the size in the width direction of the photosensitive material 14 detected by the photoelectric sensor 114. Is controlled by controlling the electromagnetic valve 268 interposed therebetween, so that the suction cup 264 that does not hold the photosensitive material 14 does not generate a suction force.

Since the cam 228 further makes a half rotation while the photosensitive material 14 is being sucked (step 1210), the support plate 232 returns to the initial position.

Here, the suction cups 264 of this embodiment have a small diameter, and two suction cups 254 are provided for each suction cup unit 254. For this reason, the suction force of one suction cup 264 applied to the present embodiment can be made smaller than the suction force of one suction cup when one large-diameter suction cup is arranged. Since there are many places where the material 14 is adsorbed, the photosensitive material 14 does not meander in the thickness direction greatly when the photosensitive material 14 is adsorbed.

In the next step 1212, while the photosensitive material 14 is being sucked by the suction cup 264, the motor 218 is driven to move the moving member 202 rightward in FIG. At this time, the conveying speed of the photosensitive material 14 of the roller pair 104 is
Are conveyed while maintaining a constant tension. 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 this reason, without being rotated on the photosensitive material 14, it is dragged and moved with the moving member 202.

When the photosensitive material 14 is conveyed by a predetermined amount according to the size of the photosensitive material 114 detected by the photoelectric sensor 114 (step 1214), the movement of the moving member 202 is temporarily stopped (step 1216) and the cutter 1 is stopped.
16 is operated (step 1218), and the photosensitive material 14 is cut. Thereby, the photosensitive material 14 having a predetermined size can be separated from the roll-shaped photosensitive material 14.

When the cutting by the cutter 116 is completed, the process proceeds to step 1220, where the movement of the moving member is resumed, and the leading end of the photosensitive material 14 is transported to a predetermined position on the surface plate 302 (step 122).
2, 1224). When the leading end of the photosensitive material 14 is placed at a predetermined position on the surface plate 302, the motor 224 is rotated in step 1226, and the cam 228 is rotated half a turn. Thereby, photosensitive material 1
4 is in a state of being sandwiched between the suction cup 264 and the platen 302.
Here, the electromagnetic valve 326 communicating with the suction device 18 is opened, and the photosensitive material 14 is sucked by the plurality of holes 308 provided in the platen body 306 (step 1228).

The platen 302 has a three-layer structure in which a pattern forming plate 310 is sandwiched between a platen body 306 and a base plate 312.
Can be generated for each pattern space according to the size of the pattern space. Therefore, since the holes 308 in only the portion where the photosensitive material 14 is placed act to suck air into the pattern space, no unnecessary suction is performed.
The photosensitive material 14 can be reliably adsorbed. The absorption of the photosensitive material 14 by the surface plate 302 is continued until the exposure 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 formed of a sponge-like soft member, even if the pattern space is large (8 places) as in the present embodiment, each pattern can be formed by a simple punching operation. The cost can be reduced with good performance. In addition, this pattern forming plate 310
A spacer 318 is inserted into the circular hole 316 of the screw 32.
When it is held between the base body 306 and the base plate 312 at 0, it is only crushed to the axial dimension (2 mm) of the spacer 318, so that the pattern can be formed reliably.
Since the sponge-like soft member applied to the pattern forming plate 310 is a closed cell, air does not leak.

Next, at step 1230, the suction of the photosensitive material 14 by the suction cup 264 is released, and the cam 228 is again rotated half a turn, so that the photosensitive material 14 and the suction cup 264 are separated from each other. At this time, the photosensitive material squeeze roller 274 remains mounted on the photosensitive material 14.

When the suction of the photosensitive material 14 by the suction cup 264 is released and the photosensitive material 14 is separated from the photosensitive material 14, the moving member 202 temporarily moves to the frontmost position, and then moves along the rail 210 to return to the initial position (step 1232). ). At this time, the photosensitive material squeeze roller 274 is moved while rotating on the photosensitive material. Thus, bubbles generated between the photosensitive material 14 and the surface plate 302 can be squeezed, and the photosensitive material 14 can be closely adhered onto the surface plate 302. That is, the platen 302
In the case where the peripheral portion of the photosensitive material 14 cannot be reliably absorbed by only the suction using the hole 308, or
Even in the case where the photosensitive material 14 itself is deformed in the thickness direction due to the surrounding environment or the like, the squeezing action of the photosensitive material squeezing roller 274 makes it possible to surely bring the photosensitive material 14 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.

In step 1300, the two motors 348 are driven synchronously to move the rack 340 upward through the gear box 350 in FIG.

The platen 302 is provided with two slide shafts 364, and the vertical movement of the platen 302 is guided by the slide shafts 364.
Is moved vertically while maintaining the parallel state.

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, document film transport control (see FIG. 37) is performed.

First, at step 1400, the motor 776 is set in a state where the original film 16 is set in the film loading section 700.
To move the support base 728 to the exposure unit 400 along the guide shafts 718, 720. Here, in a state where the shielding plate 790 is detected by the photoelectric sensor 792 on the left side of FIG.
1402) Stop the movement of the support base 728 (Step 1)
404).

The support base 728 is supported by the guide shaft 718 via the rollers 748 and 754 when the support base 728 is located in the film loading section 700. The guide shaft 718 is separated from the guide shaft 720 of the exposure unit 400 on the side where the rectangular hole 726 is provided. However, the rollers 748 and 754 are provided at six locations (three locations on one side) of the support base 728. Even if the rollers 748 and 754 at the leading end in the moving direction are separated from the guide shaft 718 by the movement of the support base 728, the other four Since the support base is supported by the guide shaft 718 at the point, the roller 74 at the tip
8, 854 smoothly guide shaft 718 to guide shaft 720
You can move on to When the intermediate rollers 748 and 754 move from the guide shaft 718 to the guide shaft 720, the leading rollers 748 and 754 are supported by the guide shaft 720, and the rear rollers 748 and 754 are supported by the guide shaft 718. You can move smoothly. Further, the rear end roller 74
8 and 754, the leading and middle rollers 748 and 754 are supported by the guide shaft 720, so that the rollers can move smoothly. That is, since the support base 728 is supported by the guide shaft 718 or 720 at at least four places, the movement is smooth even if the guide shaft 718 and the guide shaft 720 are separated from each other.

As the support base 728 moves to the predetermined position of the exposure unit 400, the lid 730 opened by the support base 728 rotates around the shaft 734 with the biasing force of the torsion coil spring 736, and shields the rectangular hole 726. It is closed via the member 738. Therefore, light can be prevented from entering the exposure unit 400 from the rectangular hole 726.

When the support base 728 is at a predetermined position of the exposure unit 400, the overlay sheet 708 and the surface plate 302 are set at positions 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 to drive the chain 784. As a result, the overlay sheet 708 is moved together with the chain 784, and is turned over by the gear
Moved above 0A. With this operation, the original film 16 placed on the overlay sheet 708 is placed on the photosensitive material 14.

When the overlay sheet 708 is disposed above the gear 780A and the original film 16 is placed on the photosensitive material 14, the process proceeds to step 1502, the motor 348 is driven again, and the platen 302 is further raised. Here, when the photoelectric sensor 354A detects the shield plate 356 (step 1504), the drive of the motor 348 is stopped (step 1506), and the rise of the surface plate 302 is stopped. In this state, the platen 302 and the positioning plate 786 are positioned, and the photosensitive material 14, the original film 16, and the 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 occurs in the groove 328 formed in the platen body 306,
The peripheral edge of the overlay sheet 708 placed on the groove 328 is sucked (step 1508). As a result, the platen 302
And overlay sheet 708 with photosensitive material 14 and original film 1
6 can be clamped and held.

When a predetermined time has elapsed after the suction of the overlay sheet 708 in the groove 328 (step 1510), in step 1512, the motor 436 of the exposure unit 400 starts driving. The drive of the motor 436 is transmitted to the shaft 430 via the belt 434 and the wheel 432, and the sprocket 424 rotates. As a result, the chain 426 wound around the sprocket 424 is driven, and the support plate 406 is moved from the front to the back of the device by the rail 4.
Moved along 04.

At this time, the squeeze roller 438, from which the high-order portion 444A of the cam bracket 444 has climbed, is placed on the surface plate 302 via the overlay sheet 708 through the slope portion 444B.
As the support plate 406 moves along the rail 404, the squeeze roller 438 moves while rotating on the overlay sheet 708. Further, the photosensitive material 14, the original film 16, and the overlay sheet 708 are suction-contacted on the surface plate 302. As a result, air existing between the overlay sheet 708 and the surface plate 302 is pushed out, and the photosensitive material 14 and the original film 16 on the surface plate 302 are pushed out.
Can be completely adhered.

When the support plate 406 reaches the rear end of the apparatus, the squeeze roller 438 is gradually separated from the overlay sheet 708 by the cam bracket 444. When the support plate 406 is stopped, in step 1514, the solenoid 442 is excited, and the actuator 442A is retracted. Thus, the squeeze roller 438 is lifted up and held via the suspension bracket 440. Here, since the squeeze roller 438 has climbed up the cam bracket 444, a small solenoid 442 having a short excitation force and a short distance to which the load of the squeeze roller 438 is applied during the lifting stroke can be applied.

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

First, at step 1600, the motor 468 is driven.
Filters (B, B) corresponding to the type of the original film 16 (Y, M, C and black plate) and the type of the photosensitive material 14 (positive, negative)
G, R, or black) is placed on the slit hole 476A.

In step 1602, when the support plate 406 returns to the original position from the back side of the apparatus, the solenoid 456 is driven, the opening / closing shutter 452 opens, and the slit hole 446A is opened.
Therefore, the light beam from the fluorescent lamp 448 is emitted from the slit hole 446A via a lens (for example, a self-occurring lens).

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

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

When the support plate 406 returns to its original position, the platen 302 is lowered by driving the motor 348 (step 1700) to a position where the photoelectric sensor 354B detects the shielding plate 356 (step 170).
2, 1704). Next, in step 1706, the film loading unit 7
The motor 782 attached to the support base 728 of 00 rotates in the same direction as described above, and the overlay sheet 708 rotates half a rotation with the driving of the chain 784. As a result, the original film 16
Can be placed on the overlay sheet 708 again. When the overlay sheet 708 is moved, the electromagnetic valve 336 is closed, and the platen of the overlay sheet 708 is closed.
Adsorption on 302 is stopped. When the placement of the original film 16 on the overlay sheet 708 is completed, step 170
In step 8, the support base 728 is moved to the film loading unit 700 by the drive of the motor 776, and is supported by the guide shaft 718. Here, since the lock of the small lid 704 is released, the grip 706 of the small lid 704 is gripped, the small lid 704 is opened, the original is separated with the next color-separated original film 16, and the above exposure control is repeated a predetermined number of times. (Step 1016 of the main routine).

When the exposure is completed, the support base 728 is moved to the film loading unit 700, and waits while being supported by the guide shaft 718. Then, the process proceeds from step 1016 of the main routine to step 1018, and the exposed photosensitive material transport control is performed. (See FIG. 41).

First, in step 1800, the platen 302 is driven down by the motor 348 to the lowermost position where the photoelectric sensor 354C detects the shielding plate 356 and stopped (steps 1802 and 1804).

Next, the motor 218 of the photosensitive material conveying section 200 is driven (Step 1806), and the moving member 202 is moved along the rail 210. When the suction cup 264 is moved by a predetermined amount to the leading end of the photosensitive material 14 (Step 1808), the movement of the moving member 202 is stopped (Step 1810), and the process proceeds to Step 1812 to drive the motor 224. This lowers the support plate 232,
The photosensitive material 14 is held between the suction cup 264 and the platen 302. Here, the electromagnetic valve 268 communicating with the suction device 18 is opened to open the suction cup 264.
The photosensitive material 14 is adsorbed by the
4 is released (step 1814), and the support plate 232 is raised again to hold the photosensitive material 14 in a sucked state (step 1816). At this time, the electromagnetic valve 326 is closed, and the adsorption of the photosensitive material 14 on the surface plate 302 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 proceeds to step 1820 to start the rotation of the drive roller 504A. At this time, the solenoid 512 is operated, and the driven roller 504B is moved in a direction away from the driving roller 504A. Thus, even if the tip of the photosensitive material 14 adsorbed on the suction cup 264 is slightly curled, the photosensitive material 14 is easily guided between the driving roller 504A and the driven roller 504B, and can be reliably inserted between the rollers.

When the suction cup 264 is stopped to the very tip (step 182)

824), stop the operation of the solenoid 512 (step 18).
26). Accordingly, the driven roller 504B is moved in a direction in which the driven roller 504B comes into contact with the driving roller 504A, and the photosensitive material 14 is held. Next, at 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 the original position.

In the next step 1830, the rotation of the drive roller 504A is resumed at the deceleration V, and the photosensitive material 14 is conveyed toward the processor 600.

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, photosensitive material 1
4 is nipped and conveyed by the roller pair 504, guided by the gap between the upper guide plate 516 and the lower guide plate 518, and nipped and conveyed by the roller pair 514.

Here, when the leading end of the photosensitive material 14 reaches the upper part of the photoelectric sensor 544 in step 1902, it is detected by the photoelectric sensor 544 and the motor 530 is driven (step 1904).

By driving the motor 530, the helical gear 528 rotates via the worm gear 534, and the rotating shaft 526 rotates clockwise in FIG. Accordingly, the lower guide plate 518 is rotated from the solid line position in FIG. 24 to the imaginary line position with the swing base 524, and the lower surface of the photosensitive material 14 is opened.

Next, in step 1906, the transport speed of the roller pair 514 is set to the same speed (V
Decelerate to _FILM or V _PAPER ). This allows the roller pair 50
The photosensitive material 14 between the roller pair 4 and the roller pair 514 is slackened, and the slack is formed in a substantially U-shape. When the rear end of the photosensitive material 14 passes through 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 sandwiched between a pair of rollers 604 of the processor unit 600. The transport speed of this roller pair 604 is
The speed is slightly faster than the transport speed of 14. For this reason, the photosensitive material 14 is conveyed while being tensioned between the roller pair 514 and the roller pair 604. Here, since the one-way clutch 606 is attached to the roller pair 514, a predetermined tension state can be maintained.

The photosensitive material 14 is gradually transported to the processor section 600,
When the rear end of the photosensitive material 14 passes through the roller pair 514 and passes through the photoelectric sensor 554 (step 1908), the photoelectric sensor 5
The signal from 44 causes motor 530 to rotate in reverse (step 191).
0), the lower guide plate 518 is
The figure is rotated from the imaginary line position to the solid line position. Thus, the next conveyance of the photosensitive material 14 can be reliably guided.

Next, a developing process is performed in step 1022 of the main routine. That is, in the processor section 600, the photosensitive material 1
4 is first immersed in the developing tanks 612 and 614, guided by the roller pair 624 of the processing rack 622 and the guide plate 626 and transported in a substantially U-shape, and transported in the order of the bleach-fixing tank 616 and the washing tanks 618 and 620. It is processed. The processed photosensitive material is guided to the drying section 640 by the roller pair 642, and the roller pair 64 of the drying section 640.
It is pinched and transported by 3. During this transfer, fan 648 and heater
The hot air generated in 650 is discharged from the opening 646 of the duct 644 and applied to the photosensitive material 14 to perform a drying process. After the drying process, the photosensitive material 14 is taken out from an outlet 22 formed in the casing 12.
