  • Method and apparatus for reading a bar code on a moving sheet
    Patent number: 5008520
    Abstract: Apparatus and method have been conceived whereby cut sheets having a bar code printed thereon can be read while such sheets are moving. A fixed scanner for reading the bar code has an elongated window such that a light beam being generated by the scanner will have a width that is no greater than the width of the smallest space between adjacent bars of the symbol. Because of the elongated configuration of the light beam, sufficient reflectivity occurs such that a good reading can be obtained with the use of such a fixed beam scanner.
