Abstract

A laser distance-measuring device includes a laser-transmitting portion, a laser-receiving portion, a coupling portion, an inclination-measuring portion, a signal-processing portion, and a display. The laser-transmitting portion emits a laser beam, and the laser-receiving portion receives the laser beam. The coupling portion interconnects the laser-receiving portion and the signal-processing portion. The inclination-measuring portion detects an inclination angle of the laser beam. The signal-processing portion processes the signals received from the laser-receiving portion and the inclination-measuring portion and sends the result to the display. The display receives and displays the result of processing by the signal-processing portion.
