Abstract: READ/WRITE MACHINE FOR MAGNETIC STRIPED DOCUMENT CARD A read/write machine for a document card having a stripe of magnetic material thereon, the machine including a magnetic read/write head and a pair of nipped roils between which the card moves for transporting the card and particularly its stripe of magnetic material over the read/write head. Controls are included for selectively returning the card to its original position in the machine after a reading or writing operation has occurred for allowing the operator to remove the card from the machine, or alternately automatically moving the card in a second pass over the head in the same direction as the first pass of the card thereover so that any data written on the card during its first passage over the head may be read therefrom by the head, or alternatively causing the card to move in three forward passes through the machine, with the third pass being used for checking the magnetic bits as previously recorded and previously read during previous forward passes of the card through the machine.

Abstract: METHOD OF TRANSPORTING CARDS IN A PUNCHED CARD READER In a card transport for a punched card reader in which the bottom card in a card hopper is moved sideways before moving forwards into the card reading zone, each card, as it reaches the bottom of the hopper, is moved sideways through a distance less than the width of the card such that the perforations in the card are moved out of registration with the perforations in the card immediately above it, and interlocking of adjacent cards is thus obviated.

Abstract: A processing machine, particularly a reader, for punched document cards including a hopper for a deck of the document cards, pick rolls disposed beneath the hopper in such position as to feed the document cards transversely thereof from the bottom of the hopper, a vertically movable hopper bed for moving the deck onto and off of the pick rolls to make them effective or ineffective, a deck lifter positioned beneath the card deck in the hopper for supporting one side of the card deck after the bottommost card has been moved transversely thereof partially out from underneath the other cards in the deck, driving rolls for moving the bottommost card longitudinally after it has been partially so moved from underneath the rest of the deck and means operative for reading punched holes in the document card on continued longitudinal movement of the card.
