Abstract
A portable and convenient electronic distance measuring apparatus using a laser beam and a supersonic wave is provided. A predetermined height is measured using a supersonic sensor and a laser pointer is rotated at the predetermined height to radiate a laser beam at a target object so that a distance to a target object at which that laser beam is pointing can be accurately measured using a resistance value corresponding to a rotation angle of the laser pointer
