Abstract: An apparatus and method for printing a graphic design on a hard plastic workpiece such as a credit card blank includes a thermal printing element which is supported by a head assembly that has been designed a single link, to have low mechanical compliance in a horizontal plane and yet to allow the print head to align with a print roller. A cleaning assembly is further provided which includes a pair of cleaning rollers having an adhesive coating; and a novel arrangement for stripping particulate matter away from the cleaning rollers after a predetermined number of cards have been cleaned. A number of stepper motors are provided to perform the cleaning and printing functions. The stepper motors are controlled by a local control system which monitors a number of sensors provided on the cleaning and printing stations and is subservient to an overall system controller. The invention further includes a novel method of operation, a cassette for use with the printing station and a novel thermal printing foil.

Abstract: A magnetic stripe encoding apparatus (24) encodes information onto a magnetic stripe (22) of a card (20). A card carriage (26) moves the card (20) along a card transport path between a top rail (28) and a bottom rail (30). The magnetic stripe (22) passes an encoding write head (36) and a read head (40) for writing and verifying information on the stripe (22). Heads (36, 40) mount on a bracket (44) which allows only twisting motion and movement toward and away from the card (20) so that good contact is maintained between the magnetic stripe (22) and the heads (36, 40). One embodiment of the card carriage (26) includes spring biased pawls (60, 62) which are biased into the card transport path for engaging the card (20) and rotate away from the card transport path so that the pawls 60,62 do not engage the card (20).

Abstract: An embossing module for an automatic embossing machine utilizes a pair of opposed embossing element carrying wheels driven by oscillating bail arms which directly engage the embossing punch and die elements. An electromechanical interrupter mechanically decouples motion of the bail arm from the embossing elements in the event of a failure. The printwheels are driven by separate motors utilizing separate position encoders and common servo command circuits.

Abstract: An apparatus for feeding cards from a storage magazine to an automatic embossing system including an input hopper and card picking mechanism for engaging a card after it is stripped from a supply stack in the input hopper. The card is positioned by a transfer mechanism to receive embossed data from rotating embossing wheels. An output hopper receives good cards and rejected cards are deposited into a reject box.
