ABSTRACT:
An optical marking apparatus includes: a laser illuminator mounted in a housing for emitting a laser optical line for marking purpose, and an angle-variating device provided in the housing; whereby upon an angular rotation of the apparatus, the laser illuminator will outwardly project a laser line which is angularly corresponding to the rotating angles of the apparatus, thereby producing angle-variable laser lines for angular marking uses.
