Abstract
Document guide systems and methods employing a document platen are provided. According to an illustrative embodiment, a document guide system employing a document platen includes a document platen having a first, document-faceable side and a second, opposing side, and a document support sub-system adjacent the first side of the document platen. The document support sub-system and the first side of the document platen are adapted to receive a document therebetween, and the document platen forms an aperture adapted to allow electromagnetic radiation therethrough.

A document guide system employing a document platen, the document guide system comprising:
- a document platen having a first, document-faceable side and a second, opposing side;
- and
- a document support sub-system adjacent the first side of the document platen, the document support sub-system comprising one or more bands to hold the document against the first side of the document platen when the document moves along the first side of the document platen and between the one or more bands and the first side of the document platen;
- wherein the document support sub-system and the first side of the document platen are adapted to receive a document therebetween;
- wherein the document platen forms an aperture adapted to allow electromagnetic radiation therethrough;
- wherein the second side of the document platen forms an indent having angled sides, and the aperture is located at approximately an apex of the indent;
- and
- wherein the document platen has an entry edge and an exit edge and the document support sub-system further comprises a first post adjacent the entry edge of the document platen, the first post having an upper portion and a lower portion, and a second post adjacent the exit edge of the document platen, the second post having an upper portion and a lower portion;
- wherein the one or more bands comprises an upper band and a lower band;
- wherein the upper band is wrapped at least partially around the upper portion of the first post at least partially around the upper portion of the second post;
- and
- wherein the lower band is wrapped at least partially around the lower portion of the first post and at least partially around the lower portion of the second post.
A document guide system employing a document platen, the document guide system comprising:
- a document platen having a first, document-faceable side and a second, opposing side;
- a document support sub-system adjacent the first side of the document platen;
- one or more electromagnetic radiation sources aimed at the aperture of the document platen to illuminate at least a portion of the document at the aperture of the document platen;
- and
- an imaging device aimed at the aperture of the document platen to capture an image of at least a portion of the document at the aperture of the document platen;
- wherein the document support sub-system and the first side of the document platen are adapted to receive a document therebetween;
- wherein the document platen forms an aperture adapted to allow electromagnetic radiation therethrough;
- wherein the second side of the document platen forms an indent having angled sides, and the aperture is located at approximately an apex of the indent;
- and
- wherein the one or more electromagnetic radiation sources are positioned on an opposite side of the document platen than the imaging device.
A document guide system employing a document platen, the document guide system comprising:
- a document platen having a first, document-faceable side and a second, opposing side, the document platen further having an entry portion and an exit portion, the entry portion having an entry edge and the exit portion having an exit edge, wherein the document platen further comprises:
- a first roller coupled to the document platen and located at least partially within a cutout portion of the entry edge of the document platen;
- and
- a second roller coupled to the document platen and located at least partially within a cutout portion of the exit edge of the document platen and
- a document support sub-system adjacent the first side of the document platen, the document support sub-system comprising a guide plate positionable adjacent the first side of the document platen to form a document passage between the guide plate and the first side of the document platen;
- wherein the document support sub-system and the first side of the document platen are adapted to receive a document therebetween, the document having a direction of travel from the entry portion to the exit portion of the document platen;
- wherein the document platen forms an aperture adapted to allow electromagnetic radiation therethrough;
- and
- wherein the first roller and the second roller are rotatable to facilitate movement of the document in the document direction of travel;
- wherein the guide plate is attachable to the document platen;
- and
- wherein the guide plate has a top side, the document platen has a top side, and the guide plate further comprises a support lip protruding from the top side of the guide plate, the support lip protruding toward the document platen when the guide plate is in position adjacent the first side of the document platen, the support lip attachable to the top side of the document platen.
A document guide system employing a document platen, the document guide system comprising:
- a document platen having a first, document-faceable side and a second, opposing side, the document platen further having an entry edge and an exit edge;
- a document support sub-system adjacent the first side of the document platen, wherein the document support sub-system and the first side of the document platen are positioned to allow a document to pass between the document support sub-system and the first side of the document platen, and wherein the document platen forms an aperture located at approximately a midpoint between the entry edge and the exit edge;
- one or more electromagnetic radiation sources aimed at the aperture of the document platen to illuminate at least a portion of the document platen;
- and
- an imaging device aimed at the aperture of the document platen to capture an image of at least a portion of the document at the aperture of the document platen, the imaging device positioned on an opposite side of the document platen than the document support sub-system, the imaging device having a line of sight substantially perpendicular to the first side of the document platen,
- wherein the document support sub-system comprises a guide plate positionable adjacent the first side of the document platen to form a document passage between the guide plate and the first side of the document platen;
- wherein the document guide system further comprises a belt to hold the document against the first side of the document platen and move the document through the document passage and across the aperture of the document platen;
- wherein the one or more electromagnetic radiation sources are positioned on the opposite side of the document platen as the imaging device;
- and
- wherein the imaging device is adapted to capture the image of the at least a portion of the document using electromagnetic radiation from the one or more electromagnetic radiation sources that is transmitted through the document.
