PURPOSE:To obtain a printing head device capable of printing even on a printing medium with rough surface by a dot matrix method by independently supporting dot printing parts aligned in one row with plural lines. CONSTITUTION:Dot printing parts 1-1-1-7 in plural lines are independently supported on plural plate spring 3-1-3-7 attached to a supporting lever 4. A printing head device 10 is contacted with a printing medium 12, e.g., electric cable, etc., through a heat transfer tape 14, heating pen tips 2-1-2-7 provided at the tops of the dot printing parts are exactly contacted with the curved surface of the printing medium 12, and thereby a mark is clearly printed. |
