ABSTRACT:
A video scanning arrangement for scanning and digitizing documents, and having a scanner actuable to scan a document on a tablet beneath the scanner. The scanner is attached to a horizontal arm member which is in turn attached to and movable up and down a vertical support member which in turn is attached to the tablet. Two light arms are pivotally attached to the horizontal arm member and each light arm has a light source attached to its nonpivoting end. Each light arm is normally folded against the horizontal arm member for storage when the video scanning arrangement is not in use, and the light arms are extended to move the light sources away from the arm member when the video scanning arrangement is to be used. The light sources are energized to illuminate a document on the tablet when the scanner is actuated to scan a document.
