1. A laser reference device comprising:
- a housing including a reference surface adapted to be mounted against a vertical surface;
means for mounting the housing to said vertical surface;
a chassis mounted for rotation relative to the housing;
a collimated light source on the chassis;
an inclination sensor that senses the angular orientation of the chassis; and
a leveling mechanism including a motor for rotating the chassis from a first position to one of a plurality of second positions in response to the angular orientation sensed by the inclination sensor.

Abstract
A chassis can be electro-mechanically rotated about an axis. The chassis contains a laser module and an inclination sensor. A laser beam and/or a laser line or plane can be emitted from chassis using a lens or reflector to focus the light in the desired beam or plane shape. The inclinometer/accelerometer senses the spatial orientation of the chassis and a microprocessor drives a motor through a motor control to adjust the angular orientation of the chassis. Preset angular orientations may be programmed into microprocessor that define predetermined angular orientations of the chassis.
