    摘要: A bar code reader includes a line sensor having a scanning range large enough to scan two or more bar codes. A portion of the scanning range having a size corresponding to a single bar code is determined as a reading range. A reading range comparator 35 determines when a bar code is positioned within the reading range, so that no other bar code within the scanning range will be read. The reader also has error detection to determine whether counted numbers of bars fall within a permissible range for a given bar code symbology.
