Abstract
A bar code reader for an article (17) which is moved at least substantially in one direction (26) has a scanner (12) which generates a scanning light beam (11) which scans a surface (18) of the article (17) linewise, a light receiving arrangement (13) which includes an electronic evaluation circuit (14) with which bar codes (16) applied to the surface of the article (17) and scanned by the light beam (11) can be recognized and which is arranged outside of the parth of movement (20) of the article (17) and directed towards the front surface (18) of the article (17) as seen in the direction of movement. A detection means (27, 28) for the location of the scanning surface (18) at which the scanning is to start, and optionally a detection means (29) for the speed of movement of the article (17) are connected to an electronic control and evaluation circuit (14) which acts on an advance means ( 30, 31) for the displacement of the scanning line (23) in such a way that the spacing of the scanner (12) from the scanning line (23) on the surface (18) of the article (17) remains at least substantially the same.
