1. In a scanning system for reading indicia having parts of different light reflectivity, a scanning head comprising:

  • (a) a housing having an elongated body portion including a front region, a rear region, and an intermediate body region extending between the front and rear regions;

    (b) indicia-detection means for generating a light beam directed along a light path toward indicia to be read, and for receiving reflected light from the indicia to produce electrical signals representative of the indicia;

    (c) a keyboard disposed on the rear region of the housing out of the light path for enabling manual data entry without manually blocking the light beam;

    (d) a display disposed on the front region of the housing for displaying information;

    (e) window means mounted on the intermediate body region of the housing between the keyboard and the display, said window means being light-transmissive and configured and positioned in the light path of the light beam to permit the light beam to pass through and window means and unobstructedly travel exteriorly of and past the front region of the housing over the display; and

    (f) read-control means for actuating the indicia-detection means to initiate reading of an indicium.
