2. Description of the Related Art An image is printed on a photosensitive lithographic printing plate (hereinafter referred to as "PS plate") by a stencil machine, developed, and then printed on a rotary press. In this case, the PS plates are placed one by one on the punch table by hand, and the plate bending is performed so that the PS plate holes are used as the positioning reference for the printing by the printing plate and the plate is bent to be wound on the rotary press. A punch hole serving as a position reference is provided. At present, the breeding punch hole and the plate bending punch hole are commonly used, and the reference position for printing is performed by abutting the end surface of the PS plate at a predetermined position of the rotary press.

In this case, it is necessary to form at least one set of punch holes (generally, a circular hole and an elongated hole are formed) near the end of the PS plate. In order to perform punching automatically, it is necessary to position the PS plate on the platen before sending it to the plate-making device and punch holes with the punching device arranged corresponding to the platen.

For positioning on the surface plate, after placing the PS plate on the surface plate, the positioning pins are made to project to the two sides sandwiching a part of the corners, and the other two sides are pressed by the pusher. By doing so, positioning is performed. As a result, the necessary end portion of the punch hole can be inserted between the base portion and the movable portion of the punch device. The movable section is provided with a punch blade, and the movable section is moved while the PS plate is inserted between the base section and the movable section, so that the punch blade makes a punch hole in the PS plate. You can

The PS plate having the punched holes is transferred to the plate-making device or the like in the next step by the discharging device.

However, when the PS plate is transferred to the next step, since a part of the PS plate is inserted between the base part and the movable part of the punch device, if it is sucked up by a suction cup or the like as it is and raised. Since the PS plate may interfere with the punch part, the punch device is conventionally retracted. However, if the punch device is movable with respect to the surface plate, punching is performed by repeating the movement. The position may be displaced, which is not preferable.

In consideration of the above facts, the present invention is capable of smoothly ejecting a photosensitive lithographic printing plate from which a punching process has been completed from a surface plate without causing the punching holes to be displaced. The purpose is to get the system.

A punch hole is punched by the puncher 294 or the puncher 296 at the leading end in the conveyance direction 2. This punch hole is used as a reference for printing by the plate breeding apparatus and as a reference for plate bending for loading into a rotary press.

When the PS plate 12 is punched, the suction on the fixed surface plate 244 side is released. Next, the servo motors 250 and 260 are driven, and the moving surface plate 246 is moved in the XY directions. Thereby, the PS plate 12 can be pulled out from the accommodating portion 300 of the punchers 294, 296, 298. Here, the air cylinder 332 of the discharge device 310 is driven, the suction cup support frame 334 is lowered, and the PS plate 12 is sucked by the suction cup 336. After the PS plate 12 is adsorbed, the suction plate support frame 334 moves up again, whereby the PS plate 12 is taken out of the surface plate 242. At this time, the PS plate 1 is moved by the moving surface plate 246.
