Claim 0:
1. A marking system comprising:
a laser marker which includes
an excitation light generation section that generates excitation light,
a laser light output section that generates laser light based on the excitation light generated by the excitation light generation section and emits the laser light,
a laser light scanning section that irradiates a workpiece with the laser light emitted from the laser light output section and two-dimensionally scans a surface of the workpiece; and
a condition setting storage section that stores printing conditions used for controlling the laser light output section and the laser light scanning section;
an image acquisition section that captures an image of the workpiece in an area scanned two-dimensionally by the laser light scanning section to generate captured images including at least a part of the workpiece;
a pass/fail determination section that determines pass/fail of printing applied to the workpiece using the captured images acquired by the image acquisition section;
a history storage section that stores, as history information in a time-series order, a plurality of determination results including at least an NG determination result among determination results obtained by the pass/fail determination section, the captured images used for acquisition of each of the determination results, and a plurality of pieces of state information at the time of acquisition of each of the determination results among a plurality of types of state information indicating states of the laser marker, in a state of being associated with each other corresponding to each of the determination results;
a display section that displays at least one of a first display area for displaying the plurality of determination results stored in the history storage section in a time-series order and a second display area for displaying the captured images respectively corresponding to the plurality of determination results in a time-series order;
a receiving section that receives an operation of selecting one or more of any of the NG determination results displayed in the first display area and the captured image displayed in the second display area and corresponding to the NG determination result; and
a control section that controls the display section such that at least the state information stored in the history storage section and associated with the NG determination result or the captured image selected via the receiving section is displayed on the display section among the plurality of types of state information.
