ABSTRACT OF THE DISCLOSURE An apparatus of projecting luminous lines on an object by a laser beam, the apparatus comprising a laser beam generator wherein the laser beam has a width, a condensing lens for focusing the laser beam on the object, and a reflector located at a position subsequent to the condensing 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, whereby the laser beam is reflected at different points on the reflecting surface, crosswisely of the laser beam at different angles, thereby securing sector-shaped continuous luminous lines.
