Abstract
A system for identifying a bar code label affixed to a rod wherein the bar code label including each bar thereof generally circumferentially spans on the rod an angle (the bar code angle) greater than 180.degree. and less than 360.degree. about the rod's longitudinal axis. The system includes a bar code reading optical scanner and a rod positioning mechanism. The scanner has a light beam from a single source and creates two scanning lines which superimposingly intersect at an angle which is greater than 360.degree. minus the bar code angle and which is less than or equal to 180.degree.. The rod positioning mechanism colinearly (or close enough to such) aligns the rod's longitudinal axis with the intersection line of the scanning lines so that the bar code label may be identified independent of the rotational position of the rod about its longitudinal axis.
