PURPOSE:To perform prescribed working with good productivity at a high speed and to decrease noise or oscillation by providing >=2 optical means for irradiating laser light and oscillating the respective optical means around the prescribed shafts. CONSTITUTION:A raw fabric 100 is delivered by a spreader 104 from a raw fabric roll 106 onto a slat conveyor 102. Laser light from laser oscillators 128, 228 arrive at respective laser heads 112, 212 via transmission means. The laser light pass further through beam expanding means and lenses and are reflected by mirrors so as to focus on the fabric 100. The mirrors are oscillated around the shafts by the 1st and 2nd mirror driving parts 114, 116 so that the laser light RA is scanned on the fabric 100 according to a required pattern. The laser light RB is also scanned by the 1st and 2nd mirror driving parts 214, 216 on the fabric 100 so as to draw a prescribed pattern. The two patterns are formed on the fabric 100 and the fabric is cut. |
