Abstract
A distance measuring device of laser beam using type has a laser diode for producing laser beams. A scanning mechanism projects the laser beams against an object and includes a polygon mirror to and by which the laser beams are directed and reflected. A receiver mechanism receives the laser beams reflected by the object. A control unit measures the period required for the laser beams to make the trip around the object. The polygon mirror is so arranged as to be rotated about a first axis and swung about a second axis.
