ABSTRACT:
A compact optical scanning apparatus includes a motor driven hollow drive shaft through which scanning light beams are projected. A mirror mounted on one end of the drive member deflects the light beams to the side of the drive member, said light beams impinge on the interior surfaces of a conically shaped ring of mirrors. The ring of mirrors will deflect the light beams downwardly towards a circular mirror mounted horizontally which reflects the light beams towards a ring of pattern forming mirrors mounted perpendicular to the circular mirror. The pattern forming mirrors will reflect the light beams through an aperture in the scanning apparatus in the form of a scanning pattern. A gear mechanism mounted between the ring of mirrors and the drive shaft rotates the ring of mirrors in a direction opposite to that of the drive shaft.
