OPTICAL MARKING SYSTEM HAVING MARKING MODE SELECTING FUNCTION

摘要

An optical marking system is disclosed, in which a light beam of a preset wavelength is generated by a light source (11). An optical system (60) receives the light beam generated by the light source (11) and directs the received light beam in a present direction. A pattern generator (18) includes a pattern forming section and a non-pattern forming section. Further, a control section (50) controls the optical system (60) to effect a first mode, in which the light beam is directed to the pattern forming section of the pattern generator (18), to form a predetermined pattern and a second mode, in which the light beam is directed to the non-pattern forming section of the pattern generator (18). The first and second modes are effected in a preset sequence.
