Arranging Record Cards or Binary Record Card Images

When it is anticipated at the time a batch of record card documents is prepared, that they will be returned for processing in batches such that the cards are not uniform with respect to face up/down, front/back relationship, the following procedure will guarantee the desired uniform arrangement prior to further processing.

Two row positions on opposite sides of the horizontal axis of the card are reserved in each of two columns, which are on opposite sides of the vertical axis of the card. During preparation, all cards are uniformly punched in only one (e.g., "upper left") of the positions so reserved. Upon receipt, the cards are placed in the sorter hopper regardless of front/back, up/down arrangement. The machine is set to examine the "upper left" reserved hole position and selects the entire batch into two decks; those in which a punch was detected are all arranged uniformly (in the case of the example, they are "face forward, top edge up"). The remaining cards in which no punch was detected in the "upper left" reserved hole position, are passed through the sorter again (without rotating the deck) with the machine set to select out those cards which are punched in the "lower" position of the same column. This time, the selected (punched) cards are removed from the sorter and this deck is rotated about its horizontal card axis to be in the same arrangement as the selected cards from the previous pass. The rema...
