Abstract: A laser scanner according to an embodiment of the present invention comprises: a housing; a window coupled to the upper surface of the housing; a motor mounted on the inner upper end of the window; a mirror slantly connected to the rotary shaft of the motor so as to reflect light; a light source arranged under the mirror so as to emit a laser beam toward the mirror; a PCB which is erected in the lateral direction of the mirror and which has an opening through which the laser beam reflected from the mirror passes; a reference sheet which is erected inside the window, and which is erected at a point separated from the PCB in the horizontal direction so as to spread and reflect the laser beam having passed through the opening; a light-transmissive lens arranged between the light source and the mirror so as to standardize, as parallel light, the laser beam emitted from the light source; a light-receiving element for receiving the laser beam, which is diffusely reflected from the reference sheet so as to pass through the opening; and a light-receiving lens for concentrating, at the light-receiving element, the laser beam, which is diffusely reflected from the reference sheet so as to pass through the opening.
