Abstract
A laser optical apparatus includes first laser emitting source for emitting a first laser beam, second laser emitting source for emitting a second laser beam, common deflector for deflecting both of the first laser beam and the second laser beam, wherein a direction in which the first laser beam is emitted from the first laser emitting source is substantially parallel with a direction in which the second laser beam is emitted from the second laser emitting source, and wherein the first laser emitting source and the second laser emitting source are disposed at positions different in the directions of the laser beams.
