Abstract
An apparatus for imaging books or other bound documents which includes a cradle for supporting a book and an optical system positioned above the cradle. The optical system is mounted for movement along a vertical axis toward and away from the cradle. It includes an upper portion supporting a camera and mirror arrangement and a lower portion comprising a platen assembly. The upper and lower portions are mounted for independent movement along the vertical axis over a first range of travel remote from the cradle, and are coupled for movement as a single unit over a second range of travel, toward and proximate to the cradle. When the upper and lower portions are coupled, the optical system has an optical path of a predetermined length extending from the platen surface, through the mirror arrangement and through the camera.
