Abstract
A data-bearing card is transported past a reading, writing or other communication head by at least one drive element connected to an electric motor through a preselected gear train. The mechanism moves the card at speeds corresponding to a preferred range of rates at which data borne by the card is intended to pass the communication head, and does so with a minimum of 'jitter'. In one particular embodiment, the gear train includes a worm screw driving a worm wheel for rotation with the drive element. In another embodiment, the electric motor is supported on a base oriented substantially parallel to the card being transported, and a shaft carrying the drive element and a first gear of the gear train is supported for rotation by at least one side plate detachably mounted to the base.
