Abstract
A punched card reader includes a base member for slidably receiving a punched data card having a plurality of columns and rows. Along one edge of the base member is a row of apertures corresponding in number and spacing to the rows on the data card. The base member further includes a centrally located strobe aperture. A strobe generator is slidably mounted on one face of the base member. The strobe generator includes a central column of slots disposed perpendicular to the row of apertures on the base member and disposed so as to pass over the strobe aperture as the inserted data card displaces the strobe generator away from the row of apertures on the base member. The slots correspond in number and in spacing to the columns on the data card. Adjacent to one face of the base member is a plurality of light sources aligned with the row of apertures and centrally located strobe aperture. Adjacent to the other face of the base member is a plurality of light sensors aligned with the row of apertures and central strobe aperture of the base member. As the data card is inserted into the reader the punched holes of the card create a signal received by the row of light sensors. Simultaneously as the card displaces the strobe generator a strobe signal is received by the sensor aligned with the strobe aperture. The combination of signals provides the correct data input. The subject reader further includes means for detecting the correct position and orientation of a card as well as the last readable position on the card.
