ABSTRACT:
An ink pen is provided with a protective cover apparatus to protect the ink pen print head against damage caused by the ingress of dirt and debris, the accumulation of solidification of ink, and the like. The protective cover apparatus has a resilient shield bent in a curve that includes an arch. The shield may be mounted to the ink pen and move between a protective position and a stowed position. In the protective position, the arch is protectively positioned over the print head. In the stowed position, the shield may be retracted into a cavity provided in the ink pen.
