  • Patent number: 3976857
    Abstract: A method of and an apparatus for reading a manually fed data carrier are disclosed. The data carrier has at least one line of coded positions and is fed manually past reader means including at least one pair of reader means which viewed in the direction of motion of the data carrier are spaced apart by a distance less than the extension of a coded position in said direction. Said pair of reader means detects the direction of motion of the data carrier each time a transition between two successive positions passes said reader means. If the detected direction is opposite to the given read-out direction, the count of a counter is increased with one unit. If the detected direction corresponds with the given direction, the count of the counter is reduced with one unit provided that the count exceeds zero. If the direction corresponds with the given direction and the count is zero, read-out result is fed out.
