1. A laser reference device disposable on a working surface, comprising:
- a housing having an outer reference surface that defines a reference plane;
a laser light generator mounted within the housing for generating laser light and projecting a fan-shaped laser light beam outside the housing immediately adjacent and substantially parallel to the reference surface; and
an aiming device for adjusting a position of the laser light generator,wherein the reference surface is located immediately adjacent the working surface when the device is placed on the working surface, and the laser light beam projects substantially parallel and immediately adjacent to the working surface.

Abstract
A laser reference device includes at least one planar or flat surface and an internal laser light source for generating a laser light beam. A lens inside the device may convert the laser light into a fan-shaped beam, and project the beam adjacent the planar or flat surface of the housing. The fan-shaped beam thus projects along that surface of the housing. If the laser leveling device is placed with the flat surface on a table or floor, for example, the fan-shaped beam will be in a level plane. This allows a user to place the laser leveling device on a surface and generate a laser light to align surfaces or objects, such as objects on a wall.
