Abstract
In a card reader, the transducer head is supported at one end of the guide path by a spring-loaded, pivoting arm. The spring is located adjacent the head and urges the head against the card as it passes under the head. The pivoted arm forces the head to follow a slightly arcuate path as it moves in a direction transverse to the card. With this head-support system, the guide path need only extend from approximately the pivot point of the arm to a point a short distance beyond the head and the card can be inserted laterally into the guide just behind the head. The card is read by moving the card longitudinally past the head a distance approximately equal to the length of the card so that it exits the guide just after it passes under the head.
