Scanner with a wing-shaped fluorescent tube housing and dual-faceted scan window

摘要

A hand scanner employs either uniformly or variably frosted scan windows to control illumination. For scanning color documents including books and magazines, a hand scanner employs a fluorescent tube mounted a certain distance above the lower surface of the scanner housing. At the fluorescent tube ends, corresponding to the illumination "dead space" of the fluorescent tube, the underlying portion of the scanner housing is recessed towards the tube.
