PURPOSE: A controller for controlling a reflection angle of laser beam is provided to irradiate the leaser beam to a measuring target by using a reflective mirror without shifting a position of a laser beam generator. CONSTITUTION: A controller for controlling a reflection angle of laser beam includes a frame(3), a balance portion(6), a mirror(7), a plurality of permanent magnets(8a,8b,8c,8d), a plurality of electromagnets(9a,9b,9c,9d), an LED, and a plurality of photo cells. The frame(3) is horizontally installed on an upper surface of a PCB by a fixing portion. A through-hole(1) is formed at a center of the frame(3). A through-hole(5) is formed at a center of the balance portion(6). The mirror(7) is combined with the through-hole(5) of the balance portion(6). The permanent magnets(8a,8b,8c,8d) are adhered on the balance portion(6) and the mirror(7). The electromagnets(9a,9b,9c,9d) are installed on an upper portion of the PCB. The LED is installed on the PCB. The photo cells are installed on the PCB.
