Abstract

Improved scanner designs are provided to improve imaging and reduce errors during the scanning process. Embodiments disclosed include, for example, the use of dual cameras to improve imagery and reduce the scanner enclosure size, synchronized lighting techniques during the scanning sequence, shielded lens for the camera scanner, a scanner enclosed on at least three sides, adjustments to scanner lighting based on the levels of ambient lighting, a combined branding and scanner apparatus, a gimbaled scanner mount, and a tilted platen with stop for document alignment.

Claims

1. An improved scanning device, comprising:

an optical element for scanning;

an enclosure surrounding the optical element on the top, bottom, and along at least three sides so as to shield the optical element from ambient light sources, said enclosure defining an opening for access to the interior of the enclosure, said enclosure having an interior surface comprising a non-reflective finish; and

a platen positioned within the interior of the enclosure for receipt of a document for scanning, said platen comprising a contact element disposed so as to engage and position the document within a field of view of said optical element for scanning.

2. An improved scanning device as in claim 1, further comprising at least one scanner light positioned within the interior of the enclosure in a manner that minimizes direct-reflections to the optical element.

3. An improved scanning device as in claim 1,

wherein said platen is tilted within the interior of the enclosure, said platen titled relative to the opening of said enclosure so as to provide for positioning of documents therein to slide against said contact element and to minimize direct reflections from ambient lights sources.

4. An improved scanning device as in claim 1, further comprising:

a gimbaled mount to which said optical element is attached;

said gimbaled mount having multiple pivot points configured for allowing the adjustment of the orientation of said optical element relative to said platen.

5. An improved scanning device as in claim 4, further comprising locking elements for fixing the position for said gimbaled mount about the multiple pivot points.

6. An improved scanning device, comprising:

an optical element for scanning;

an enclosure surrounding the optical element on the top, bottom, and along at least three sides so as to shield the optical element from ambient light sources, said enclosure defining an opening for access to the interior of the enclosure, said enclosure having an interior surface comprising a non-reflective finish;

wherein said enclosure defines an input slot for receipt of a ticket, and the scanning device further comprises;

a platen positioned within the interior of the enclosure;

a motor positioned below the platen and configured to receive the ticket from the input slot and advance the ticket to said platen; and

a printing device positioned proximate to said motor and configured for marking the ticket.

7. An improved scanning device, comprising:

an enclosure defining an opening;

a plurality of optical elements for scanning an item, said optical elements positioned within said enclosure;

at least one light source positioned in said enclosure so as to illuminate the item during scanning, said at least one light source positioned within the interior of said enclosure in a manner that minimizes direct reflections to the two or more optical elements; and

a platen positioned within the interior of the enclosure for receipt of the item for scanning, said platen comprising a contact element disposed so as to engage and position the item within a field of view of said optical elements for scanning.

8. An improved scanning device as in claim 7, wherein said platen is tilted within the interior of said enclosure and positioned relative to the opening of said enclosure so as to provide for positioning of items therein against said contact element.

9. An improved scanning device as in claim 7, wherein said platen is positioned relative to the opening of said enclosure so as to minimize direct reflections from ambient light sources.

10. An improved scanning device as in claim 7, further comprising:

a plurality of gimbaled mounts to which said plurality of optical elements is attached;

each said gimbaled mount having multiple pivot points configured for allowing the adjustment of the orientation of a respective optical element relative to said platen.

11. An improved scanning device as in claim 10, further comprising locking elements for fixing the position of each said gimbaled mount about the multiple pivot points.

12. An improved scanning device, comprising:

an enclosure defining an opening;

a plurality of optical elements for scanning an item, said optical elements positioned within said enclosure;

at least one light source positioned in said enclosure so as to illuminate the item during scanning, said at least one light source positioned within the interior of said enclosure in a manner that minimizes direct reflections to the two or more optical elements;

wherein said enclosure defines an input slot for receipt of a ticket and the scanning device further comprises;

a platen positioned within the interior of the enclosure;

a motor positioned below said platen and configured to receive the ticket from the input slot and advance the ticket to said platen; and

a printing device positioned proximate to said motor and configured for marking the ticket.
