ABSTRACT:
A sheet inspection apparatus for a sheet-fed offset printing press includes an endless conveying unit, a plurality of gripper units, and an inspection unit. The conveying unit has a conveying path and a return path and conveys a sheet delivered from a printing unit. The gripper units are supported by the conveying unit at a predetermined interval along a sheet conveying direction to grip one end of the sheet. The inspection unit is arranged on an opposite side of the conveying path with respect to the return path to optically inspect a printed state of the sheet conveyed on the conveying path. The inspection unit is arranged at a position where an optical inspection operation for the sheet at an inspection position on the conveying path is not impeded by the gripper units traveling on the return path.
