<p>PROBLEM TO BE SOLVED: To provide a laser marking system which can surely print various data while effectively preventing the environment of production line from being polluted and is downsized to replace an traditional inkjet type in the existing production line. SOLUTION: By scanning a laser beam in a two-dimensional direction by laser scanning device 5 which is emitted by pulse output signal from a laser beam source 3, the scheduled mark is printed on the material to be marked. A printer head 7b adjoining to the material to be marked and an incoming head 7a to which a laser beam scanned in a two-dimensional direction is incoming are connected by optical fiber group 17 with the number of optical fibers meeting the number of dots which composes a mark to be printed.</p> |
