ABSTRACT:
A reader-writer for magnetic cards substantially reduces "jitter" or chattering vibrations which otherwise imperil the accuracy of the read-write functions. The read-write head is itself mounted rigidly for operating while the magnetic card passes along a planar tray surface. A soft rubber anvil roll is mounted directly opposite, for free idling rotation on the same shaft which impels a rubber driving wheel.
In contrast with conventional constructions using a spring-mounted head or anvil, the present rigidly mounted head in combination with the free idling soft anvil roll avoids the generation of, and damps out, vibrations, which otherwise might follow from exciting forces such as irregularities in driving friction. The greatly improved accuracy makes feasible the use of debit cards, and has unexpectedly reduced head wear.
