Multi-angle laser scanner
First Claim
1. A scanning device adapted to scan an interface surface provided on a product item, the interface surface having disposed thereon coded data indicative of an identity of the product item, the product item being provided in a sensing region, the scanning device including:
- (a) a beam generator for emitting at least one scanning beam, the scanning beam being directed in first and second orthogonal directions to thereby generate a raster scan pattern over a scanning patch provided in the sensing region;
(b) at least one beam controller for directing the at least one scanning beam along selected ones of a number of patch beam paths, each patch beam path extending into the sensing region at a respective angle;
(c) a sensor for sensing at least some of the coded data on the interface surface of the product item as the product item passes through the sensing region; and
(d) a processor for determining, using at least some of the sensed coded data, product identity data indicative of the identity of the product item.

56. An automated check-out for scanning a product item having an interface surface associated therewith, the interface surface having coded data disposed over a substantial portion of the interface surface, the coded data being indicative of an identity of the product item, the check-out comprising:
-
(a) a conveyor adapted to convey the product item through a sensing region; and
(b) at least one scanning device adapted to;
i. direct at least one scanning beam;
1. in first and second orthogonal directions to thereby generate a raster scan pattern over a scanning patch provided in the sensing region;
2. along selected ones of a number of patch beam paths, each patch beam path extending into the sensing region at a respective angle;
ii. sense at least some of the coded data on the interface surface of the product item as the conveyor causes the product item to pass through the sensing region; and
iii. generate, using at least some of the sensed coded data, product identity data indicative of the identity of the product item. - View Dependent Claims (57, 58, 59, 60, 61, 62, 63, 64, 65)
