ABSTRACT:
A reader for reading encoded data on cards, badges and the like, which cards and badges can be of differing thicknesses, having specially adapted drive roller pairs each comprising a drive roller of a first durometer and a pinch roller of a second durometer, arranged to efficiently capture the badge or card and apply a positive drive force to it. The drive roller is fixed in position and of a relatively high durometer, while the pinch roller is at contact with the drive roller in the absence of a transported card or badge, but is adapted to be displaced against a spring force to accommodate the thickness of the badge or card being read. The efficiency of capture is a function of the relative durometers of the two respective rollers of the drive roller/pinch roller pair, as well as the degree of spring force provided on the pinch roller.
