Handheld laser scanner
First Claim
1. A laser scanning device for scanning an interface surface provided on a product item, the interface surface having disposed thereon or therein visible information relating to the product item and coded data which includes, at a plurality of locations on the interface surface, a corresponding plurality of coded data portions, each coded data portion being indicative of an identity of the product item, and at least some of the coded data being coincident with the visible information, the scanning device including:
- (a) a housing being held by a user in use;
(b) a laser for emitting a scanning beam from the housing, the scanning beam being directed in first and second orthogonal directions to thereby generate a raster scan pattern over a scanning patch, the scanning patch being arranged such that it exposes at least one of the plurality of coded data portions when the product item is provided in a sensing region;
(c) a sensor for sensing the at least one exposed coded data portion;
(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, the coded data indicative of a plurality of reference points on the interface surface.

Abstract
A laser scanning device adapted to scan an interface surface provided on a product item, the interface surface having disposed thereon coded data which includes, at a plurality of locations on the interface surface, a corresponding plurality of coded data portions, each coded data portion being indicative of an identity of the product item, the scanning device including: a housing adapted to be held by a user in use; a laser for emitting a scanning beam from the housing, the scanning beam being directed in first and second orthogonal directions to thereby generate a raster scan pattern over a scanning patch, the scanning patch being provided in the sensing region such that it exposes at least one coded data portion; a sensor for sensing the at least one exposed coded data portion; a processor for determining, using at least some of the sensed coded data, product identity data indicative of the identity of the product item.

54. A method of scanning an interface surface provided on a product item, the interface surface having disposed thereon or therein visible information relating to the product item and coded data which includes, at a plurality of locations on the interface surface, a corresponding plurality of coded data portions, each coded data portion being indicative of an identity of the product item, and at least some of the coded data being coincident with the visible information the method including:
-
(a) holding a grip portion of a scanning device housing; (b) activating the scanning device to thereby cause a scanning beam to be emitted from the housing, the scanning beam being directed in first and second orthogonal directions to thereby generate a raster scan pattern over a scanning patch; and
,(c) positioning the product item in a sensing region, such that the scanning patch exposes at least one of the plurality of coded data portions, the scanning device being responsive to; (i) sense the at least one exposed coded data portion; and
,(ii) generate, using at least some of the sensed coded data, product identity data indicative of the identity of the product item, the coded data indicative of a plurality of reference points on the interface surface. - View Dependent Claims (55, 56, 57, 58, 59)
