Patent ID: 7560661

Claim:
A laser beam machine for processing an article to be processed with a laser beam comprising: (a) a processing scanner, which comprises: a beam-scanning mechanism, said beam-scanning mechanism including a Z-scan unit and an X-Y scan unit, said Z-can unit including a focusing lens which focuses a laser beam and is movable in a direction parallel with a Z axis, and said X-Y scan unit including a pivotable scanning mirror for performing scanning with said scanning mirror pivotally rotating about an X axis parallel with said Z axis and about an Y axis perpendicular to said X axis; and a tilt mechanism for pivotally rotating said X-Y scan unit about said X axis; and (b) two article position controllers for controlling in a coordinated manner the position of a mounted article to be processed in accordance with the direction of the laser beam from said processing scanner, said article position controllers being disposed in the irradiation path of the laser beam from said X-Y scan unit which is positioned at a pivot end of said tilt mechanism, and wherein a focal point of said laser beam is a processing spot, a transfer range of said focal point being changed by said tilt mechanism, and said article position controllers being disposed substantially symmetrically with respect to the center of the transfer range of said focal point.
