Abstract
A hand-held optical reading device, commonly called a wand, for reading a field of printed characters. The wand includes a light source for illuminating the printed characters, a photodiode array and a lens for collecting reflected light and forming an image on the diode array corresponding to the printed characters. Apertures are formed in the lower portion of the wand housing for projecting light from the light source onto the surface upon which the characters are printed. The projected light forms a pattern on the surface which is used for visually aligning the wand with respect to character field.
