LASER PROCESSING DEVICE, LABEL CREATION DEVICE AND LASER PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a laser processing device being capable of excellently forming a cutline in any of a place where a scanning speed of a laser beam is fast and a place where the scanning speed is slow while being capable of suppressing formation of a wide side inclined plane along the cutline.SOLUTION: A laser processing device comprises: a first liquid discharge head 32a assigning first heat quantity reduction liquid Ba along a label side 104a of a first scanning scheduled place 106a; a second liquid discharge head 32b assigning second heat quantity reduction liquid Bb having a smaller reduction amount of heat quantity in comparison with the first heat quantity reduction liquid Ba along a label side 104a of a second scanning scheduled place 106b; and a laser irradiation section 4 forming a cutline 103 to the first scanning scheduled place 106a and the second scanning scheduled place 106b by scanning the first scanning scheduled place 106a by a laser beam in a low-speed first speed range and scanning the second scanning scheduled place 106b by the laser beam in a high-speed second speed range.SELECTED DRAWING: Figure 1
