PROBLEM TO BE SOLVED: To provide a laser level that is inexpensive and usable by the general public. SOLUTION: The laser level disposable on a reference surface includes: a housing; a laser diode disposed within the housing for emitting a laser beam along a path; a lens disposed in the path for converting the laser beam into a planar beam. The planar beam thus forms a line on the reference surface. The laser level also includes an electronic distance measurement circuit disposed within the housing for measuring distance. The distance measurement circuit includes a display for showing the measured distance. COPYRIGHT: (C)2011,JPO&INPIT
