Abstract
Abstract A hand scanner support and paper guide apparatus is provided for mechanically scanning a thin sheet using two scanners originally designed to be hand-held. The apparatus includes a base assembly, a top assembly, and a hinge assembly connecting the base assembly and the top assembly together. The base assembly includes a base housing which includes a planar upper wall which serves as a flat surface along which the thin sheet is moved. A base scanner unit is supported by the base assembly a spaced distance below the planar upper wall as the thin sheet is moved past the base scanner unit. A guide assembly is connected to the base housing for guiding the thin sheet in a straight path as the thin sheet is moved along the planar upper wall. A drive assembly, a portion of which is housed within the base housing, is provided for moving the thin sheet past the base scanner unit. A top scanner unit is supported by the top assembly a spaced distance above the planar lower wall as the thin sheet is moved past the top scanner unit. A pinch roller is supported by the top housing. The pinch roller and the drive roller are positioned opposite each other. The pinch roller is driven by the thin sheet as the thin sheet is pinched between the drive roller and the pinch roller and as the thin sheet is driven by the drive roller.
