Abstract
In a printing head, an actuator pin positioned within a magnetic field is bent to form at least one V-shaped portion and is fixed at the end portion thereof. When current flows in the actuator pin during printing, the actuator pin is caused to be expanded and contracted by an electromagnetic force to thereby print a dot. A plurality of guide grooves are formed on both side faces of a conductive common guide plate. The end portion of the actuator pin is fixed at the guide groove in an insulating condition, and the tip of the actuator pin is movably fitted in the guide groove in an electrically conductive state.
