Abstract
A shoe for a bar code wand consists of an upper cylindrical portion having a through hole for receiving and frictionally engaging a portion of the scanning head of the wand, a downwardly sloping inwardly converging shoulder located within the hole near the bottom of the cylindrical portion serving to limit the extent of penetration of the wand into the hole, and a pair of parallel opposing contact arms extending downward from the bottom of the cylindrical portion, for providing a predetermined gap between the reading tip of the wand and a bar code label. The ends of the contact arms are radiused to permit angular movement within a range of the wand from perpendicular orientation with a bar code label being read by moving the assembly of the wand and shoe across the label, while maintaining the desired gap.
