PURPOSE: An alignment beam device having an auto adjustment unit is provided to be capable of automatically controlling the position of a laser and constantly locating a new laser at the same position after replacement. CONSTITUTION: An alignment beam device is provided with a laser(10) for generating the beam for alignment, an alignment part(50) for controlling the position of the laser(10), and a support part(40) for supporting the laser(10) by using the elastic force caused by the motion of the laser(10). The alignment part(50) further includes a motor for generating driving force, a driving shaft driven by the motor, a plate installed at the driving shaft, and a measurement part for measuring the coordinate of the plate. Preferably, a plurality of alignment parts are installed at the alignment beam device for shifting the laser(10) horizontally and vertically.
