Abstract
Abstract A scanning system and method for reading coded indicia carried on containers, etc., the system and method including means for generating in a predetermined sequence a first light pattern, and a second light pattern, and means for focusing same at a window over which containers carrying the coded indicia are positioned. The disclosure also includes a mirrored rotatable polygon structure including a plurality of mirrors, some of which are inclined at a positive angle and the others which are positioned at a negative angle with respect to the polygon axis of rotation as well as means for adjusting the incline of the mirrors.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
112 words
A rotatable polygon comprising a hub, said hub having a plurality of flat faces positioned about the circumference thereof, said faces intersecting each other at corners and each of said corners having a plurality of locating slots, a plurality of O rings of elastomeric material, each O ring positioned in a different locating slot of each of said corners, and lying over said faces, a plurality of supports each having a mirror coupled thereto, and adjustable means supported by said hub and coupled to said supports for urging said supports against said O rings, adjustment of said adjustable means orienting said mirrors with respect to the axis of rotation of said polygon.
Claim 2
Dependent Claim
