Abstract
A distance measuring device is provided that measures the distance to an object surface. The distance measuring device includes a housing, a measuring signal projecting and detecting means, a laser indicating device, a display, a circuit, a series of battery cells, a switch and plurality of operation buttons. The measuring signal projecting and detecting means emits a signal to an object surface and detects the reflected signal therefrom. The laser indicating device projects at least one laser beam onto a surface to form at least one visible reference line vertical to the direction in which said measuring signal is emitting. And, the circuit calculates the distance between the laser beam and the object surface.
