Abstract

　マルチビーム走査装置は、非平行光が射出される光源部と、所定のパワーを有し、該光源部から射出された光に対して作用する光学素子と、を有する第一光学系を複数組備えるとともに、各第一光学系の後段に配設され、各第一光学系から射出された複数のレーザー光全てが共通に入射し、該レーザー光を偏向する第一偏向器と、該レーザー光の発散度を変更する共通光学系と、を有する第二光学系と、光源部から射出されたレーザー光が光学素子に入射するときの入射光路を平行移動させる光路シフト手段と、を有し、第一偏向器に入射する全ての光は、該第一偏向器の略同一位置に入射するとともに、各光学素子は、当該光学素子の焦点距離だけ当該光学素子から離れた位置で、各光学素子の光軸が交差するように配設されている構成にした。
