Abstract
A document scanner for scanning an open book includes a housing and a wedge-shaped transparent platen supported by the housing. The platen defines an upper surface configured to support a book in a face-down position, and a lower surface opposite the upper surface. The platen includes a first platen portion and a second platen portion joined at a vertex to thereby define the wedge-shape of the platen. The document scanner further includes a scan head moveably supported by the housing. The scan head is configured to move generally parallel to the first platen portion and the second platen portion.
Claims31
A document scanner for scanning an open book, comprising:
- a housing;
- a wedge-shaped transparent platen supported by the housing and defining an upper surface configured to support a book in a face-down position, the platen further defining a lower surface opposite the upper surface, the platen comprising a first platen portion and a second platen portion joined at a vertex to thereby define the wedge-shape of the platen;
- and
- a scan head moveably supported by the housing, the scan head being configured to move generally parallel to the first platen portion and the second platen portion.
A document scanner, comprising:
- a housing;
- a transparent platen supported by the housing and defining an upper surface and a lower surface, the platen comprising a first platen portion, a second platen portion, and a platen vertex hinge, and wherein each platen portion defines a mating edge, and the first and second platen portions are joined at the mating edges by the platen vertex hinge to thereby allow the mating edges of the first and second platen portions to move generally upward and away from the housing;
- a scan head moveably supported by the housing and configured to move generally parallel to the lower surface of the platen;
- and
- a scan head track supported by the housing and configured to moveably support the scan head, the scan head track comprising a first track portion, a second track portion, and a track hinge joining the first and second track portions.
A document scanner, comprising:
- a housing;
- interchangeable transparent first and second platens, each platen configured to be supported by the housing;
- a scan head moveably supported by the housing;
- a scan head track supported by the housing and configured to moveably support the scan head, the scan head track comprising a first track portion, a second track portion, and a track hinge joining the first and second track portions;
- and wherein:
- the first platen is a generally flat planar platen;
- and
- the second platen is a generally wedge-shaped platen.
A document scanner, comprising:
- a housing;
- a transparent generally wedge-shaped platen supported by the housing and defining an upper surface and a lower surface, the platen comprising intersecting first and second platen portions defining the wedge-shape of the platen, the platen being configured to support an open book on the upper surface thereof to thereby allow first and second opposing pages of a book to be presented to the respective first and second platen portions;
- a moveable scanning means configured to scan the first and second opposing pages of the book to be presented to the respective first and second platen portions;
- and
- a scanning support means configured to moveably support the scanning means in generally parallel arrangement to the first and second platen portions.
