ABSTRACT:
A distance measuring equipment which can detect a beam sending direction with a compact and simple structure is provided.
The distance measuring equipment is equipped with a scanning means which swings a reflection means in a predetermined range to scan a beam, an original point detecting means which detects the original point as a reference position of the reflecting means, and a beam sending direction operating means which calculates a direction of the sending beam reflected by the reflecting means based on a detected output from the original point detecting means.
