2 is attached.

Next, the operation of the automatic plate making apparatus 10 thus configured will be described in relation to the automatic plate making method according to the present embodiment.

First, a plurality of originals 14 are placed in a magazine 12.
When the bottom plate 30 is raised to a predetermined position after the sheets are stacked and accommodated, one end of the rocking plate 36 constituting the document position detecting means 32 comes into contact with the uppermost document 14. Therefore, the swing plate 36 rotates about the fulcrum 34 against the tension spring 38, and the other end is separated from the optical sensor 40. Therefore, the height position of the bottom plate 30 is adjusted according to the position where the optical sensor 40 is turned ON and OFF by the swinging plate 36, whereby the height position of the uppermost document 14 corresponds to the sheet-feed mechanism 16. Is always adjusted to a fixed position. When the number of originals 14 decreases, the rocking plate 36 enters between the optical sensors 40 and
Since the state becomes the FF state, the bottom plate 30 is raised, and the height position of the document 14 is adjusted again.

Then, when the second rotary drive source 52 constituting the single-wafer mechanism 16 is driven and the eccentric cam 54 connected to the rotary shaft (not shown) is rotated, the eccentric cam 54 engages with the upper end face of the eccentric cam 54. Rod 56 descends. The lowering of the rod 56 lowers the mounting plate 60 via the guide rods 58a and 58b, and the plurality of suction disks 64 attached to the mounting plate 60 move the uppermost document in the magazine 12 to the uppermost position. 1
Contact 4 At this time, the passage 62 in the mounting plate 60 is sucked through the pipe 66 under the action of a suction device (not shown),
The uppermost document 14 is suction-held by each suction plate 64 communicating with the passage 62.

As shown in FIG. 1, the original 14 is arranged at an angle, but the mounting plate 60 is
8a, 58b so as to be rotatable.
The mounting plate 60 rotates along the inclination of the document 14, and the suction plate 64 can reliably suck the document 14.

An eccentric cam 54 via a second rotary drive source 52
Is further rotated, the rod body 56 and the guide rod 58
a, 58b rise, and the suction disk 64 moves the uppermost original 14
Is lifted integrally with the mounting plate body 60 in a state of holding by suction. Then, the first rotation drive source 42 is driven, and the moving table 4 is moved via the nut member 50 under the rotation of the ball screw 46.
8 moves in the direction of arrow A. As a result, the leading end surface 14a of the document 14 held by the suction plate 64 is disposed close to the document position detection unit 70 from between the fixing table 74 and the mounting plate 76 constituting the document position detection unit 70. The sheet enters the holding plate 120 constituting the transport unit 72.

Next, the second and third solenoids 132a, 132b fixed to the moving members 116b, 116c are integrally driven, and the rods 134a, 134b are lowered. For this reason, the pressing member 136 fixed to the rods 134a and 134b descends, and the resin body 138 causes the original 1 to move.
A substantially central portion of 4 is pressed and held by the holding plate 120.
Here, since the center of the resin body 138 is formed in the shape of an arc that curves downward, the document 14 is sequentially pressed outward in both directions in the direction of the arrow B from the central portion thereof, and wrinkles and the like are formed in the central portion. It can be prevented from occurring. In this state, after the suction operation of the original 14 by the suction plate 64 is released, the fourth solenoid 14 fixed to the moving member 116d is released.
0, the pressing member 1 via the rod 142
One end of the document 14 is pressed and held by the 44 resin body 146.

As described above, the original 14 is
In a state where the document is held or before the document is held, the first solenoid 124 fixed to the moving member 116a is driven, and the rod 126 protrudes toward the holding plate 120 side so that the original on the holding plate 120 is Contact 14 For this reason,
The detection plate 128 fixed on the upper part of the rod 126 moves down to change the distance between the detection plate 128 and the distance sensor 130, and this distance is detected by the distance sensor 130. As a result, a detection operation is performed to determine whether a single document 14 is held in the transport unit 72, whether two or more documents 14 are held, or whether the document 14 is not present. Unless it is determined that one document 14 is held, it is a conveyance failure, and for example, the drive of the automatic plate making apparatus 10 is stopped.

When it is determined that one document 14 is held, the first light emitters 78a and 78b are driven, and detection light is led out to the first light receivers 80a and 80b. Here, if the leading end surface 14a of the document 14 is not arranged parallel to the direction of arrow B, for example, the first light emitter 7
8a is applied to the first light receiver 80a, while the detection light from the first light emitter 78b is applied to the first light receiver 80b.
(See FIG. 6). Then, while the movable body 86a is moved in the direction of arrow A via the first timing belt 88a under the driving action of the third rotation drive source 94a,
The movable body 86b is moved in the direction opposite to the arrow A direction via the second timing belt 88b under the driving action of the fourth rotation drive source 94b.

The movable body 86a, 86b has a fulcrum bolt 1
The rotating plates 98a and 98b are rotatably mounted via the 02 and 102. When the movable bodies 86a and 86b move in opposite directions, the original 14 held on the mounting panel 96 is It tilts in the direction of arrow B integrally with the mounting panel 96 (see the arrow in FIG. 6). More specifically, the movable body 8
The end on the 6a side moves in a direction to enter between the first light emitter 78a and the first light receiver 80a, while the end on the movable body 86b side moves from between the first light emitter 78b and the first light receiver 80b. Move in the direction to leave. Accordingly, by controlling the driving of the third and fourth rotary drive sources 94a and 94b and swinging the mounting panel 96 in the direction of arrow B, the first projector 7
8a, 78b is the first detector 80
A boundary portion between the position irradiated with the light a and the position 80b and the position not irradiated with the light is detected. Then, by stopping the swinging operation of the attachment panel 96 corresponding to the boundary portion, the leading end surface 14a of the document 14 can be aligned so as to be parallel to the arrow B direction.

After the alignment of the leading end surface 14a of the original 14 in the direction of arrow A, that is, the operation of adjusting the parallelism in the direction of arrow B is completed, the fifth rotation drive source 112 fixed to the mounting panel 96 is driven to drive the ball. Screw 114
The moving members 116a to 116d and the holding plate 120 are integrally moved in the direction of arrow B under the rotation of. Therefore, the document 14 held by the holding plate 120 and the holding members 136 and 144 is moved in the direction of arrow B, and one side of the document 14 is moved by the second light emitter 82a and the second light receiver 84.
a.

At this time, the detection light is led out from the second light emitter 82a toward the second light receiver 84a. The position where the detection light is blocked by the document 14 and is not irradiated on the second light receiver 84a, The arrow B on the document 14 is detected by detecting
The alignment work in the direction ends. Note that manuscript 1
In the case where the widths of the four light emitting devices 4 are different, the other second light emitting devices 82b to 82d and the second light receiving devices 84b to 84d may be selectively used.

After the alignment of the document 14 in the directions indicated by the arrows A and B is completed, the third and fourth positions are set.
The rotation drive sources 94a and 94b are driven synchronously, and the transport unit 72 moves a predetermined distance in the direction of arrow A while holding the document 14 and stops at a desired position on the document table 150. Next, the vacuum pump 1 constituting the suction mechanism 20
The document 52 is driven, and the document 14 is suction-held at a desired position on the document table 150 via the tube 154.

After the suction of the document 14 is started, the second to fourth solenoids 132a, 132b and 140 are deenergized, the holding members 136 and 144 are raised, and the holding action of the document 14 is released. Then, the third and fourth rotary drive sources 94a and 94b are driven to rotate in the opposite direction, and the transport unit 72 is rotated in the opposite direction to the arrow A direction via the first and second timing belts 88a and 88b. Move to the magazine 12 side. At this time, since the rotating body 111 supported by the mounting panel 96 rolls on the original 14 sucked and held by the original table 150, the entire surface of the original 14 is uniformly and flatly formed on the original table 150. Can be imitated.

The transport unit 72 returns to the original receiving position,
As described above, while the sheet feeding operation of the original 14 from the magazine 12 is performed, the work of performing the photographing process on the plate material 22 corresponding to the original 14 is performed on the original platen 150. That is, the plate material 22 selected according to the desired size is sent out from the plate material holding unit 162a or 162b, cut into a predetermined size via the cutter 164, and then charged by the charge box 166. . Further, the exposure table 16
8 and an imaging operation is performed via the illumination lamps 178 a to 178 d and the optical system 176.

After the photographing is completed, the driving of the vacuum pump 152 constituting the suction mechanism 20 is stopped, and the document 14 on the document table 150 is sucked and held by the suction plate 182 constituting the discharge mechanism 28 and is conveyed in the direction of arrow A. And receive magazine 26
Is discharged. On the other hand, the plate material 22 after the photographing is conveyed to the developing unit 172 via the conveying system 170 and subjected to development processing, and then discharged to the discharge unit 174.

In this case, in this embodiment, the original 14 taken out of the magazine 12 via the sheet-feeding mechanism 16 is held by the transport unit 72, and the leading end surface 14a of the original 14 is moved in the direction of arrow A and An operation for positioning in the direction of arrow B is performed. Therefore, when the originals 14 stacked and stored in the magazine 12 are held by the transport unit 72 via the sheet feeding mechanism 16, even if the originals 14 are misaligned, the originals 14 are transported to the photographing position S. Immediately before the positioning, it can be automatically positioned to a desired posture. Therefore, the plurality of originals 1 stacked and housed in the magazine 12
Reference numeral 4 denotes a sheet taken out one by one by the sheet-feeding mechanism 16, and is always arranged with high precision on the document table 150 at the photographing position S, and performs a good photographing process on the plate 22 corresponding to the document 14. It becomes possible.

Thus, the operation of attaching and detaching the original 14 to and from the original platen 150, which has conventionally been performed manually, is automated, and a series of operations from sheet-feeding the original 14 to the receiving magazine 26 are performed. Can be automatically performed, and in particular, an effect is obtained that a continuous and efficient automatic plate-making operation can be easily performed using a plurality of originals 14.

Further, in this embodiment, after the document 14 is stopped at a predetermined position on the document table 150, the suction mechanism 20 is stopped.
Is driven and the original 14 is suction-fixed to the original platen 150.
Is released. For this reason, there is an advantage that the document 14 can be accurately and reliably suction-fixed to a predetermined position of the document table 150.
