摘要

A paper guide apparatus for a sheet-fed offset printing press includes a conveying unit (5), a gripper unit (7), a paper guide member (25), and an inspection unit (40). The conveying unit conveys a printed sheet (12) delivered from a printing unit. The gripper unit is supported by the conveying unit for gripping one end of the sheet. The gripper unit has a plurality of sets of grippers (10) and gripper pads (11). The paper guide unit is arranged along a sheet conveying route to guide the sheet which is being conveyed with a guide surface (26) arranged to be substantially flush with the gripper pads. The paper guide member has a plurality of suction holes (28) for drawing the sheet on the guide surface by suction and a plurality of grooves (29) formed on traveling routes of the grippers. The inspection unit inspects a printed state of the sheet which is conveyed while being drawn on the guide surface of the paper guide unit by suction. <IMAGE>
