1. In a record card reader, feeder and transport device having a ready station disposed at each of two respective junctures of three, progressively disposed, orthogonal, coplanar card transport sections, the card paths therethrough being of predetermined, restricted lengths such that cards entering either ready station may temporarily and partially overlap cards exiting therefrom to maximize the rate of card processing while maintaining the rate Of card travel at a level low enough to minimize card leading edge damage, there being card feeding and driving mechanisms operatively associated with each card path, the medial card transport section of the three aforesaid transport sections including, in combination:

  • a horizontally elongated base plate forming a card-supporting surface cooperating with a similar, superposing cover plate having a card-guiding surface in closely spaced, opposing relation to the card-supporting surface of the base plate and defining the medial card path therebetween, a continuously rotatable drive roller disposed peripherally below the card-supporting surface of the base plate, said drive roller extending partially through the base plate but being peripherally recessed with respect to its card-supporting surface, a pinch roller normally disposed peripherally above the cardguiding surface of the cover plate and actuatable through the cover plate toward said drive roller to depress individual record cards into engagement with the drive roller for feeding the same along the medial card path, and means for feeding individual record cards into the medial card path in a direction normal to and in the plane of card travel therein from a preceding card path, each card passing freely thereinto by virtue of the peripherally recessed dispositions of the drive roller relative to the card-supporting surface of the base plate and of the pinch roller relative to the cardguiding surface of the cover plate.
