Abstract: A scanner frame (20) comprises a vertical track (22) which is slidably attached at one end thereof to a horizontal track (24). The horizontal track is attached to a drawing board (28) or any other suitable flat surface. An optical imaging device (36) (i.e., an optical scanner) is slidably attached to the vertical track. A marker strip (37) comprising a series of bars (38) of uniform pitch are disposed on a surface of the horizontal track along the length thereof. These bars are detected by a sensor assembly (40) disposed on the vertical track. Another marker strip (41) comprising a series of bars (42) of uniform pitch are disposed on a surface of the vertical track along the length thereof. These bars are detected by a sensor assembly (44) disposed on the scanner.
