Abstract
Apparatus for feeding data processing record cards seriatim from the bottom of a stack to a data sensing station or the like including a pair of oscillating picker members for displacing a record card from the bottom of the stack, and a pair of sector rollers for intermittently gripping the displaced card and moving it at right angles to the direction of displacement to the nip of a set of feed rollers. Both the picker members and sector rollers are driven from a common source, the picker members being harmonically driven through a unique coupling device including a pair of flexural elements mounted at right angles to each other to give a universal action.
