  • Endless drive belt apparatus for processing card tickets with magnetic track
    Patent number: 4537125
    Abstract: A ticket (1) is driven by an endless belt (10) which is serrated on one surface. The belt engages only a fraction of the width of the ticket. At a print station which includes a dot-matrix print head (145, 146) the ticket passes over a smooth platen roller (150) which includes a portion (152) of reduced diameter in which the belt is received so that its smooth surface comes level with the rest of the cylindrical surface of the platen roller. The print head moves along a generator line of the platen roller, and the roller itself or the drive belt provide the required backing for printing on the ticket.
