摘要:
Apparatus for supporting a scanner head, the apparatus comprising: a carrier assembly (12); a bogey assembly (11); and a scanner head assembly (10), comprising a mounting for holding a scanner head; wherein the scanner head assembly and the bogey assembly are both mounted on spring bearings on the carrier assembly such that they can both move in a vertical direction, and the scanner head assembly comprises at least two collinear vertical bearings (14) which restrict movement of the scanner head assembly to vertical movement substantially perpendicular to a document path, and the bogey assembly comprises two laterally spaced bearings (13) which allow rotational movement of the bogey assembly about the scanner head mounting.
