ABSTRACT:
A printer includes a clam shell mechanism having a frame rotatably mounted on a base. A platen is mounted on the frame. A print head for acting in cooperation with the platen is mounted on the base. A locking lever mounted on the base cooperates with a shaft mounted on the first frame for selectively maintaining the first frame in a closed position. A lock control member switches the locking means between maintaining the first frame in the closed position and allowing the first frame to rotate to an open position wherein the platen is displaced from the print head.
