Abstract
There is provided a printed board machining apparatus having fewer restrictions in terms of the length of printed boards to be machined, that can be readily controlled in positioning a sheet-like workpiece and that is capable of improving the machining efficiency. Plural sets of optical scanners and fθ lenses that compose laser condensing and positioning mechanisms are disposed apart in a width direction (X direction) orthogonal to a longitudinal direction (Y direction) of the sheet-like workpiece and two sheet-like workpieces are fixed on a machining table in parallel, and in the width direction to machine printed boards on the sheet-like workpieces The disposition of the fθ lenses allows the machining of the plurality of lengthy printed boards to be completed practically at the same time or at the same time without limiting the length of the printed boards to be machined.
