Abstract

A label roll rack is provided for a barcode printer and includes a shaft rod and at least one retention bar. The shaft rod has an end coupled to a housing of the barcode printer to receive a label roll to fit thereon, serving as a support axle for the label roll. The shaft rod forms on surfaces thereof sliding slots extending in a horizontal axial direction. The retention bar has a lower end forming opposite coupling sections each having an inside surface forming a projection, which is fit in the respective sliding slot of the shaft rod to make the retention bar substantially normal to and realizing a retention condition with respect to the shaft rod, wherein the retention bar is movable in the horizontal axial direction for positioning and retaining label rolls of various sizes fit on the shaft rod. The retention bar, when moved to a free end of the shaft rod, is rotatable, with the free end of the shaft rod serving as pivoting center, with respect to the shaft rod to a horizontal axial direction to be coaxial with the shaft rod for easing mounting and dismounting of the label roll onto/from the shaft rod.
