摘要:
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. 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. The wires guided by guide holes which form a circular array at one armature end, and a row or rows at the printing end.
