Abstract
An apparatus for marking a defect detects a defect in a long sheet product transferred in a longitudinal direction by an inspection apparatus and places a mark at the defect at a position downstream of the inspection apparatus. An oil-based marking pen is contained in a container tube having a shutter for closing the tip of the pen. The shutter is opened based on a signal sent from the inspection apparatus, a mark is placed at the defect in the long sheet product by the tip of the pen pushed out of the container tube, the pen is pulled back into the container tube after the marking is completed, and the shutter is closed. The mark can be placed at the portion of the detected defect by an oil-based marking pen without causing a decrease in the marking property due to drying of the tip of the pen.
