Abstract: To improve convenience in use of a laser marking apparatus that performs marking on a workpiece to which an alignment mark is affixed. The laser marking apparatus includes a setting section, a second IF section, a movement amount monitoring section, and a marking control section, and the setting section causes a display section to display a setting-assist image, which visually indicates the alignment mark on the flexible workpiece and a trigger delay, and receives a user input for setting the trigger delay in a state where the setting-assist image is displayed.

Abstract: To perform appropriate printing on a workpiece moving along a three-dimensional movement path. A laser marking apparatus includes: a laser light output section; a laser light scanning section; a print data generation section; a marking control section; and a print pattern correction section that corrects a print pattern received by an input interface based on movement path information related to a movement path of a workpiece moving with a change in a posture in a three-dimensional space. The print data generation section generates print data based on the print pattern corrected by the print pattern correction section.
