PROBLEM TO BE SOLVED: To minutely suppress the advancing speed of a work and the deviation of the circumferential speed of a work-supporting roller by driving the roller using the movement of a carriage for moving and positioning the work in the X-axis direction. SOLUTION: A pair of work supporting rollers 23, 25 is provided on a frame 22 installed in a work shooter device 21, in a stretch in the Y-axis direction. In cutting the work by a laser beam, a first clutch member 47 is engaged with a second 77 by advancing a slide shaft 43. With an X-axis carriage 27 moved in the X-axis direction, a rack 37 provided in a clamp plate 35 is engaging with a pinion gear 53 provided in a slide shaft 43, so that the slide shaft 43 is rotated. Then, the work supporting rollers 23, 25 are synchronously rotated in the moving direction of the X-axis carriage 27 by means of a synchronous rotating mechanism. In dropping a cutting member, the engagement is released between the first and the second clutch members 47, 77, inclining and releasing the work shooter device 21. |
