摘要： A print hammer (1) for a high speed impact printer using a movable type-face-carrier, e.g., a rotatable printwheel (11). The print hammer (1) is designed to enable rotating the printwheel (11) for character selection purposes during the return stroke of the print hammer from impact position back to its rest position. While the print hammer (1)) moves in a plane perpendicular to the printer platen, back to rest position, pivotal (3) and cam means (27, 2a) cooperate to lift the hook shaped hammer head (2) up and over the printwheel (11), therefore continuously clearing the path of said rotatable printwheel.
