ABSTRACT:
A carbon ribbon shaft is provided for a barcode printer and includes a shaft rod and at least one first rotation member and one second rotation member. The shaft rod has an end coupled to a housing of the barcode printer. The first and second rotation members are fit over the shaft rod. Arranged between inside of the first rotation member and the shaft rod is a resilient element that allows the first rotation member to effect resilient rotation with respect to the shaft rod. The first rotation member has an outer surface forming sliding-resistant resilient tabs. Arranged between inside of the second rotation member and the shaft rod is a resilient element that allows the second rotation member to effect resilient rotation with respect to the shaft rod. The second rotation member has an outer surface forming sliding-resistant resilient tabs. The surfaces of first and second rotation members receive a carbon ribbon roll of the barcode printer to fit thereon. With the resilient expansion of the sliding-resistant resilient tabs of the first and second rotation members, the carbon ribbon roll is securely fixed on the first and second rotation members to thereby form a carbon ribbon shaft assembly for a modularized carbon ribbon roll.
