ABSTRACT:
There is provided a laser machining apparatus for sheet-like workpieces that allows an installation area to be reduced and that may be readily controlled. The laser machining apparatus includes a Y-table movable in X- and Y-plane directions orthogonal to a laser beam irradiated from an fθ lens, a supply reel for holding a supply-side roll which contains a sheet-like workpiece, and a take-up reel for holding a take-up side roll containing a finished sheet-like workpiece. Machining is carried out by fixing the sheet-like workpiece in the machining area on the movable table and by irradiating the laser beam while moving the movable table relative to the laser beam. At least one of the supply reel and the take-up reel is disposed on the movable table.
