Abstract
Scanning devices include an input tray shaped to hold scannable items before scanning, an output tray shaped to hold the scannable items after scanning, a series of opposing belts positioned to transport the scannable items from the input tray to the output tray, and a round roller contacting a drum belt of the opposing belts. The opposing belts are positioned to have each of the scannable items constantly be held between the opposing belts or between the round roller and the drum belt of the opposing belts while the opposing belts are transporting the scannable items from the input tray to the output tray. A scanner is positioned in a gap between two of the opposing belts, and the gap is in a process direction that the opposing belts are moving the scannable items.
