Abstract: The present invention relates to a laser line beam emitting apparatus having a laser beam emitter from which laser beam flux are emitted and an optical broad element for broadening the laser beam flux to predetermined directions in which objects to be emitted reside for drawing of a straight reference line thereon. The apparatus's housing has an improved dust protective covering fitted into an outlet thereof such that the reflected, broadened laser beam flux from the covering through the cylindrical rod lens of the laser beam emitter becomes no ghost. Preferably, such covering has a curvature formed on its inner surface such that the reflected, broadened laser beam flux therefrom through the laser beam emitter return to the inside of the apparatus.

Abstract: For purpose of both of reduction in the number of parts that contributes to lower cost, and facilitated adjustment of location of a pair of laser beams for formation of a precise straight line beam drawn on objects in the wide-angle area, there are provided an apparatus and method having an improvement in emission of a laser line beam. The improvement comprises at least two pointer units each having a laser beam source for emission of a laser beam and a collimator lens for collimating the emitted beam, and a cylindrical lens arranged ahead of the units. With an arranged relationship between the pointer units and cylindrical lens, two beam fluxes from respective units cross each other at a point where the cylindrical lens is arranged, wherein the beam fluxes are at right angles to the central axis of the cylindrical lens. The diffused beams form the straight line beam.

Abstract: The improved laser line beam emitting apparatus provides reduction in the cost and a number of the parts, simplicity of the adjustment, and allows for drawing of a straight line in the range of the wide angle. It comprises a single laser beam source unit in which a cylindrical rod lens with semitransparent and complete transparent faces produces reflectively and refractively passing laser beam therefrom.
