Abstract:
1. An optical scanner, comprising: an upper housing having an upper transparent window; a lower housing which matingly engages said upper housing to define a hollow inside space, said upper housing and said lower housing in mated engagement provide a side wall having a thickness disposed between a pair of generally flat surfaces having substantially perpendicular fixed relation to a substantially planer external face of said upper housing and said lower housing, wherein said lower housing has a lower transparent window, and said upper transparent window is viewable through said lower transparent window; a light filter coupled to the external surface of said lower transparent window which transmits light incident in substantially perpendicular relation to said lower transparent window, and wherein said light filter blocks light upon said lower transparent window incident at an angle of between about thirty five degrees and fifty five degrees; and an image sensor and image sensor driver operably located within said hollow inside space, said image sensor driven between a first image sensor position and a second image sensor position, said second image sensor position locating said image sensor in substantially abutted adjacent relation to an internal surface of said side wall which acts to reduce distance between the external surface of said side wall and the border of a scanned area of said upper transparent window.
