Abstract:
1. A laser level system, comprising: a rotating shaft; a motor coupled to the shaft adapted to drive the shaft more than 360 degrees in a single direction; a case rotatably supporting the rotating shaft; and a module housing attached to the rotating shaft, the module housing having a mechanical axis and containing a laser diode projecting a beam having a center ray, wherein the mechanical axis and the center ray of the beam am not coincident with respect to each other but define a reference plane, which is perpendicular to the rotating shaft, wherein the module housing extends from the rotating shaft, defines a hole with a center axis which contains the laser diode, wherein the laser diode has a mechanical axis aligned with the center axis and an optical axis not aligned with the center axis, wherein the center axis and the optical axis are perpendicular to the rotating shaft.
