<p>An apparatus for reference laser level setting, which has a simple structure to automatically adjust a laser beam in both transverse and vertical directions and measure an angle of inclination. The apparatus comprises a laser focusing device and a target. The target has a reflection surface for indicating a predetermined position on the target, and the laser focusing device comprises a laser oscillator including laser beam emission means rotatably supported and means for receiving a reflected laser beam; a driving device for rotating at least the laser beam emission means of the laser oscillator; and a control portion for directing the laser beam to the predetermined position of the target in accordance with the reception state of the reflected laser beam from the reflection surface of the target.</p> |
