Abstract
An improved wire dot print head for increased integrated density is provided. The wire dot print head includes a frame. A plurality of drive coils are mounted within the frame. A lever for driving print wires has a print wire mounted at one end and its other end formed as a hook to act as a rotation support member. A yoke has salients formed thereon equal in number to that of the levers disposed on its end surface. The rotation support member of each lever is retained with a recess formed within a respective yoke and an end surface of the frame and is affixed in place by a retainer spring. When an excitement current flows through the coil, the lever is caused to move so that the print wires rotate about the rotation support member causing the print wires to strike a platen.
