PURPOSE:To carry a photosensitive planographic printing plate after positioning it in the carrying width direction of the printing plate. CONSTITUTION:An insertion stage is provided in an insertion device 530. The printing plate is placed on the insertion stage. Plural reference position rollers 584 rotatably supported by a bracket are provided adjacently to the insertion stage. A pressing roller 588 is rotatably supported on the bracket 586 opposed to the rollers 584. The driving shaft of an air cylinder is connected to the bracket 586. The roller 588 presses the printing plate placed on the insertion stage toward the roller 584 by the driving of the air cylinder, so that the printing plate is allowed to abut on the roller 584. By driving a motor 576, the pressing member 572 moves to press the end face of the printing plate. |
