ABSTRACT:
A scan window apparatus for defining and identifying a selected scan window within an overall scanable surface of a scanning device. The scanable surface is defined by intersecting first and second edges. The scan window apparatus includes moveable position markers which can be moved along the first and second edges of the scanable surface to thereby define the selected scan window. A scan window illumination device is used to illuminate the selected scan window. The illumination device can be a light source directed towards the scanable surface, or a directed, focused light source to trace at least a portion of a perimeter which defines the scan window. The invention also provides for an optical scanning device having a platen, a scan window identification device allowing a user to define a selected scan window on the platen, and a scan window illumination device to illuminate the selected scan window.
