ABSTRACT:
Jitter, characteristic of gear trains used for precision movement of magnetic cards in gear driven card readers-writers, is eliminated by forming, in situ, a resilient material as a dampening arrangement in a recess in the gear to which a drive shaft is connected for driving that movement. Alternative dampening spring arrangements are disclosed.
