Abstract: A compact medium scanner (100) scans a surface (132) of a medium (134) with a beam of light (106). A medium transport mechanism (202, 206) advances the surface along a medium transport path through a scanning station. A light source (104) produces a collimated beam of light (106) that impinges upon a mirror plate (112) of a micromachined torsional scanner (108). A pair of coaxially aligned torsion bars (304) support the mirror plate (112) within the torsional scanner (108). A mirror-surface drive means (306, 312) rotates the mirror plate (112) about the torsion bars (304). A single reciprocation of the mirror plate (112) by the drive means (306, 312) deflects the beam of light (106) over a fan-shaped region having a virtually fixed vertex (128) on the mirror plate (112). Scanner optics (116, 122) direct the fan-shaped region beam of light (106) onto the surface (132) of the medium (134) then present in the scanning station to thereby scan across the medium (134) with the beam of light (106).
