ABSTRACT:
An automatic video digitizing system for document scanning wherein a document is inserted into a roller feed arrangement located adjacent a video scanning head. The system includes a front pair and a rear pair of drive rollers located respectively in front of and behind the video scanning head. The ones of each pair of document drive rollers are initially spaced apart to permit the document to be inserted through the spacing between the drive rollers without damaging the input edges of the document. Lift means are operatively connected to the drive rollers for moving the opposing drive rollers from their spaced-apart, non-feed position into contact with each other. A motor drive operates in response to a document position sensor for driving the document backwards to a predetermined starting position where a front edge of the document is located at a preset distance from the video scanning head. After the document is positioned at its starting position, the motor drive rotates the drive rollers for driving the document forward for scanning thereof.
