  • Magnetic stripe character applying module
    Patent number: 4518853
    Abstract: A module for applying a magnetic stripe character to a plastic card. A tiltable carriage moves the card along a transfer path past magnetic code applying apparatus when tilted in a first position. When the carriage is tilted into a second position, it returns along the transfer path to engage a further card while the first card is removed from the card transfer path by pinch rollers driven by a unidirectional clutch. Defective cards are removed from the card transfer path by a tiltable plate which opens a slot in the card transfer path to allow them to fall through the base plate.
