Abstract:
1. A scanning apparatus for scanning a sheet as the sheet is transported in a substantially vertical transport direction y transverse to an optical axis z that is normal to the surface of the sheet, the scanning apparatus comprising: a scan housing supporting an optical scanning apparatus and extending in the direction of a substantially horizontal axis x; a first coupling extending from a supporting frame to a first support point on the scan housing; second and third couplings extending from the supporting frame to the scan housing, wherein the second and third couplings provide axial alignment relative to the horizontal axis x, wherein, relative to the horizontal axis x, the first coupling is disposed between the second and third couplings, and wherein the second and third couplings allow at least two degrees of rotation of the scan housing with respect to the horizontal axis x and constrain movement of the scan housing in the substantially vertical transport direction y; and a transport apparatus coupled to the scan housing for aligning the sheet relative to the scan housing in the substantially vertical transport direction.
