ABSTRACT:
An apparatus projects luminous lines on an object by a laser beam and includes a laser beam generator wherein the laser beam has a width, a convex lens for limiting the width of the laser beam, and a reflector located at a position subsequent to the convex lens, wherein the reflector has a cylindrical reflecting surface adapted to allow the reflecting luminous lines to reflect unidirectionally at gradually decreasing angles with respect to the reflector. Thus, the laser beam is reflected at different points on the reflecting surface, at different angles, thereby forming sector-shaped continuous luminous lines on an object to be marked.
