Patent ID: 8316733

Claim:
A printer comprising: an elongated shaft having a first end and a second end, the shaft having at least three flat portions between the first and second ends; an interface component having an aperture extending through at least a portion of the interface component; a coupling device coupling the interface component to the shaft, the coupling device being a generally modified c-shape, the coupling device having an internal surface and an external surface; wherein the coupling device further includes an opening providing access to the internal surface and further for facilitating the receiving of the shaft within the coupling device; the coupling device including at least one hinge operable to modify the size of the opening of the coupling device to receive and secure the shaft therein; and the external surface of the coupling device engaging the aperture of the interface component, such that when the coupling device is placed about the shaft and the external surface of the coupling device is engaged with the aperture of the interface component, the rotation of the shaft causes rotational movement of the interface component; wherein the coupling device directly contacts and is directly coupled to both the shaft and the interface component such that the coupling device is a one-piece member for coupling the shaft and the interface component, wherein the internal surface of the coupling device includes at least three channels, the at least three channels being configured to couple to the at least three flat portions of the shaft, and wherein the coupling device further includes a plurality of retainers, said retainers extending from the external surface of the coupling device, engaging the interface component and limiting the distance the coupling device can be inserted into the interface component.
