The objective of the prevent invention is to provide a laser leveler system which can prevent the error of laser irradiation due to a variation in the angle of a mirror in a laser leveler used to find out the depth or height information of a construction place with respect to a reference point in a process of performing public works or interior decoration. The laser leveler of the present invention comprises: a laser generator; a right angled mirror including a first mirror and a second mirror, wherein the normal vector of the reflection surface of the first mirror vertically crosses the normal vector of the reflection surface of the second mirror; and a mirror support unit for supporting the right angled mirror. The laser leveler of the present invention can irradiate a reflective laser always having a certain height difference while being parallel to a laser incident on the mirror by solving the problem that the position of the irradiated laser is greatly changed when there is a slight difference in the angle of reflection in using an existing laser leveler. |
