US 6,444,949 B1 · Apparatus for producing a printer head and aperture processing device

Abstract

The present invention comprises an array lens illumination system for shaping laser light in a band-like beam, a mask which is arranged in an optical path of the laser light from the array lens illumination system and on which a plurality of circular apertures are formed in a staggered shape in accordance with an arranged state of orifices formed on an orifice plate, a shift member which is arranged at the incident side of the laser light rather than the mask, and which splits the laser light incident on the mask into a plurality of beams in accordance with the number of circular apertures and irradiates the split beams onto the respective circular apertures of the mask, and a projecting lens for forming an image of the laser light passing through the mask on the orifice plate.
