摘要： 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 shift from side to side on its axis of rotation. When the pinch roll is out of alignment, such shifting occurs at each reversal in direction of rotation of the pinch roll when transporting the card. A person adjusting the pinch roll position observes this and adjusts the position of the pinch roll until such shifting stops which indicates the roll is in alignment.
