<p>PROBLEM TO BE SOLVED: To provide, in the present invention, a laser marker device which enables a variation caused by an operator in adjustment of a coil position to be reduced, thereby enabling a coil to be more surely arranged at a predetermined position.SOLUTION: First and second laser heads 13 and 14 are arrange in an outer peripheral position of a coil 2 while the laser heads 13 and 14 are apart from each other in the axial direction 2a of the coil 2. The first and second laser heads 13 and 14 are provide in such a way that they can advance and retreat by the same quantity in the directions opposite to each other along the axial direction 2a, and the first and second laser heads 13 and 14 respectively emit laser beams 13a and 14a in the radial direction 2b of the coil 2. A separate distance between the first and second laser heads 13 and 14 and a position of the coil 2 are adjusted so that the laser beams 13a and 14a are positioned at both axis ends of the coil 2, and consequently, a central position 17 between the first and second laser heads 13 and 14 and a central position 2c of the coil 2 in the axial direction 2a are made to coincide with each other.</p> |
