US Patent 7806610 Printer with cover having laterally movable hinge

A printer with a chassis, a hinge and a paper cover assembly. The chassis may have a printing head and a notch. The hinge may have an axis, and may be coupled with the chassis such that the rotational axis of the hinge is laterally movable. The paper cover assembly may be coupled with the hinge, and may be rotatable about the hinge. The paper cover assembly may have a roller and a handle. The roller may have an axis, and when the paper cover assembly is closed, the axis of the roller may be within the notch. The handle may be configured to move a cam mechanism, and when the paper cover assembly is closed and the mechanism is moved, the mechanism may act against the chassis causing the axis of the hinge to laterally move, thereby causing the axis of the roller to move out of the notch.
