LASER MARKING METHOD AND APPARATUS THEREFOR

Document Type and Number:

WIPO Patent Application WO/1995/013899

Kind Code:

A1

Abstract:

The invention relates to a method of and an apparatus for laser marking, which can enhance a production efficiency by enabling laser marking even when continuously conveying a work without intermittently stopping it. Thus a second deflector (9) of a marking apparatus comprises a mirror (10) for reflecting laser beams having passed through a mask (6), and movable lenses (16, 17) for receiving the laser beams reflected by the reflective mirror (10) and applying them onto a surface of the work (8) for making. The movable lenses (16, 17) are mounted on a moving mechanism (15) which moves in synchronism with a work conveying speed.
