1. A light scanning system for reading light-reflective indicia, comprising:

  • (a) a hand-held scanning head having a body portion and a handle portion;

    (b) means within the body portion for generating a scanning light beam and for directing said light beam along a first optical path toward said indicia for reflection therefrom;

    (c) sensor means mounted in the body portion for detecting the variable intensity of at least a returning portion of said light beam traveling along a second optical path away from said indicia back toward the head;

    (d) said handle portion being connected to said body portion and accommodating at least one printed circuit board such that said circuit board is adapted to be electrically connected to said scanning light beam generating means; and
