Here, as shown in FIG. 4A, the common transport unit 128, the photopolymer plate transport unit 130, and the switching transport unit 136 include a skewer roller 138 and a narrow belt 140.
The main part is to transport the photopolymer plate 102 (see FIG. 4B). That is, the photopolymer plate 10
2 is conveyed by the strong pinching force of the skew roller 138, and the narrow belt 140 functions as a guide plate that moves in synchronization with the conveyance.

On the other hand, the slip sheet transport section 134 is
As shown in (C), the transport system includes only the narrow belt 140, and has a structure in which the slip sheet 118 is transported by the small clamping force of the narrow belt 140.

Here, as shown in FIG. 5, the transfer portions at the respective transport portions are alternately protruded at the tips in a skewered shape, and one concave or convex tip is connected to the other convex or concave tip. They overlap so that they face each other (having a common coaxial transport path). Thereby, the photopolymer plate 1
02 and the slip sheet 118, the skewered roller 138
And the narrow belt 140 are prevented from being caught.

As shown in FIG. 3, the slip sheet 118 conveyed by the slip sheet conveying section 134 is guided to a slip sheet storage box 132 provided on the carriage 200. A pair of rollers 144 is provided at an insertion port 142 of the slip sheet 118 provided above the slip sheet storage box 132.

When it is stretched between the roller 34 and the roller 144, it is conveyed while maintaining a predetermined tension state, and jamming due to slack or the like can be prevented.

A tapered guide plate 146 whose width (in the thickness direction of the interleaf paper 118) gradually narrows is provided on the front side of the insertion opening 142. The neutralizing brushes 148 are respectively attached to the tapered guide plates 146 facing each other, and the insertion holes 142 are provided.
The charge of the interleaf paper 118 to be inserted into the paper is removed.

The pair of rollers 144 has a skewer shape, and a partition plate 150 is provided along the unevenness of the skewer shape. Thus, even if a part of the slip sheet 118 stored in the slip sheet storage section 134 comes into contact with the roller 144, the partition plate 150 can prevent the slip sheet from being caught.

As shown in FIG. 1, the photopolymer plate 102 transported by the photopolymer plate transport unit 130
Is detached from the photopolymer plate transport unit 130 in the horizontal transport state and delivered to the surface plate 110.

Here, the height of the upper surface of the surface plate 110 is lower than the horizontal transport height of the photopolymer plate transport unit 130, and has a slight gap in the transport direction. For this reason, the photopolymer plate transport unit 130
When it is discharged from the platen, the platen 110
Landing upward, the rear end in the transport direction is located closer to the front than the surface plate 110. In front of this, the surface plate 110

At this reference position, the photopolymer plate 10
The sensors 1 are located at a plurality of positions including both corners at the rear end in the conveying direction.
The pressing of the pressing plate 156 is stopped by detecting the rear end of the photopolymer plate 102 in the transport direction by the sensor 158. The sensor 158 is also used for detecting the position of the photopolymer plate 102 in the transport width direction. That is, when the platen 110 moves in the transport width direction, the corners of the photopolymer plate 102 and the sensor 158 are matched, and this is registered as the initial position of the photopolymer plate 102.

The relative position of the position of the photopolymer plate 102 moved to the initial position and the scanning exposure start position in the exposure unit 112 is determined.

And the puncher 160
As a result, punch dust generated by providing punch holes in the photopolymer plate 102 slides down in the shooter 204 toward the dust accumulation box 202 by its own weight. Thus, the punch waste is guided to the waste accumulation box 202 by the shooter 204, and the waste accumulation box 202 receives the punch waste. Therefore, the punch waste is accumulated in the waste accumulation box 202.

The platen 110 has a first position for receiving the photopolymer plate 102 from the photopolymer plate transport unit 130 (see a solid line position in FIG. 1) and a second position (see FIG. (See the imaginary line position in FIG. 1) at a constant speed (common to the movement in the conveying width direction for positioning).

The exposure unit 112 is provided with a scanning unit 164 above the conveying path of the surface plate 110, and a laser beam whose lighting is controlled in accordance with an image signal is subjected to main scanning (the surface plate 1).
10 (a direction orthogonal to the transport direction). On the other hand, the forward transport of the surface plate 110 is a sub-scanning movement,
As a result, an image is exposed (recorded) on the photopolymer plate 102 on the surface plate 110 during the forward transfer to the exposure unit 112.
Then, it is returned to the original position by the backward conveyance. The adsorption and holding of the photopolymer plate 102 on the surface plate 110 that has returned to the original position is released.
