Abstract
Abstract A portable laser diode scanning head, aimable at each symbol to be read, emits and receives non-readily-visible laser light, and is equipped with a trigger-actuated aiming light arrangement for visually locating and tracking each symbol. A compact laser diode optical train and an optical folded path assembly, as well as an interchangeable component design and an integral window construction for the head also are disclosed.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
96 words
A hand-held laser scanning head for reading indicia, said head comprising: a) a body portion; b) scanning means mounted in said body portion for scanning said media; and c) handle portion detachably fixed to said body portion and accommodating at least one printed circuit board such that said circuit board is adapted to be electrically connected to and disconnected from said scanning means upon the attachment and detachment, respectively, of said handle portion with said body portion, whereby a function of the scanning head may be charged by changing or adding to said printed circuit board.
Claim 2
Dependent Claim
96 words
A hand-held laser scanning head for reading indicia, said head comprising: a) a body portion; b) scanning means mounted in said body portion for scanning said media; and c) handle portion detachably fixed to said body portion and accommodating at least one printed circuit board such that said circuit board is adapted to be electrically connected to and disconnected from said scanning means upon the attachment and detachment, respectively, of said handle portion with said body portion, whereby a function of the scanning head may be charged by changing or adding to said printed circuit board.
Claim 3
Dependent Claim
14 words
