Abstract
An optical axis adjusting apparatus is provided and includes a laser beam source, a beam shaping prism for shaping a laser beam of elliptical flux emitted from the laser beam source into a laser beam of circular flux, a parallel shift mechanism which shifts the light rays of the laser beam in a parallel fashion, and a rotation adjusting mechanism for rotatably adjusting a parallel plate.
