Title: Uniform pressure distributing self-leveling pinch roll for magnetic card transport system

Abstract: A magnetic card transport subsystem for an electronic typewriter comprises a reversible drive roll and a coacting pinch roll which form a nip through which a magnetic card is passed. The drive roll and pinch roll coact to move the card in opposite directions. The pinch roll is so mounted that it can rock and be self-leveling to permit the full width of the pinch roll to engage the card and uniformly distribute pressure thereto. A mechanism for adjusting the pinch roll for alignment purposes is also provided.
