Abstract
Abstract A system for reading information recorded on a card in first and second rows of different code markings, wherein the recorded information can be successfully compared with stored reference code information regardless of the direction in which the card is inserted into the system. The code information on the card is arranged along a primary dimension thereof and the card is received in the system to be moved in a direction along the primary dimension, but it can be read properly whether it is inserted face up or down or whether inserted in a forward or reverse direction. The disclosed system includes means for detecting the difference between the code markings in the first and second rows, providing a signal indicating the orientation of the card, and means responsive to the difference-detecting means for providing in first and second outputs signals corresponding to the code markings in the first and second rows, regardless of the orientation of the card upon insertion. Other features include reading means for detecting markings spaced in rows located either along the centerline of the card or spaced symmetrically on opposite sides thereof; means for storing, in either forward or reverse sequence, the information code recorded on the card and means for storing the reference code in forward and reverse sequence for comparison simultaneously with the stored information code to provide the required comparison signal; means for gating to information code storage means the information code signals corresponding to the markings on the card in such a way that the information code is always stored in a forward sequence for comparison with the reference code, whether received in forward or reverse sequence as determined by the direction of insertion of the card; and a reversible counter for controlling gating means applying the information code signals to the information storage means in a sequence determined by the direction of insertion of the card.
