ABSTRACT:
A bar code scanner, comprising a scanning pattern generator for deflecting a laser beam produced by a laser source so as to generate a scanning pattern in a scanning plane, further comprises a pattern divider for intercepting and dividing at least part of the pattern generated by the pattern generator into at least two divisional patterns and for projecting the divisional patterns in a scanning plane so as to form an altered scanning pattern. Preferably, at least some divisional patterns projected in the scanning plane overlap.
