Abstract
A hand-held scanning device is disclosed in which the scanning device housing window is located such that it does not come into contact with the object being scanned while a scan is being performed. This location of the window eliminates window damage caused by contact with the object being scanned. This location also results in the window being located out of the focus area of the scanning device optical system. Accordingly, any defects occurring in the window will be out of focus and, thus, less detrimental to acquired image quality. A light source lens may be integrally formed in the same assembly as the window and this assembly may provide support for the light source.
