ABSTRACT:
A ticket transport which is capable of rapidly reciprocating a ticket to permit a single transducer to read, write and/or verify information on the ticket. Upper and lower ticket guide plates define a ticket channel through which a ticket is propelled past an adjacent transducer by a plurality of rollers driven by a stepper motor. The upper ticket guide plate is hingedly mounted to permit access to the ticket channel. The stepper motor is controlled by special circuitry adapted to overcome the inductive time constant of the stepper motor to permit rapid acceleration, for example 0 to 50 inches per second in 30 milliseconds, of the ticket with minimum power dissipation. Sensors in the transport provide ticket position information. A combined magnetic head and pressure shoe assembly is provided for adjusting the thickness of the ticket channel.
