Patent ID: 7806610

Claim:
A printer comprising: a chassis including a printing head and at least one notch; a hinge having a rotational axis, wherein the hinge is coupled with the chassis such that the rotational axis of the hinge is laterally movable with respect to the chassis; and a paper cover assembly coupled with the hinge, wherein the paper cover assembly is rotatable about the rotational axis of the hinge, and wherein the paper cover assembly includes: a roller having a rotational axis, wherein when the paper cover assembly is closed, the rotational axis of the roller is within the notch; and a handle configured to move a cam mechanism, wherein when the paper cover assembly is closed and the cam mechanism is moved, the cam mechanism acts against the chassis causing the rotational axis of the hinge to laterally move with respect to the chassis, thereby causing the rotational axis of the roller to move out of the notch.
