Abstract
A scanner of a bar code verifier is provided with a viewing window that allows the operator to align the scanner and a bar code to be scanned by the scanner. However, such a viewing window also allows external light to enter the scanner and reduce the accuracy with which the bar code is verified. This problem is solved by a scanner 1 of a bar code verifier according to the invention provided with a blind shutter 8 that can selectively open or close the viewing window 7 so that, during the operation of reading and verifying the bar code, the viewing window 7 may be closed by the blind shutter 8 to improve the accuracy with which the bar code is verified.
