PURPOSE:To obtain a head which is prevented from adhering of paper dust and in which a heat-sensitive paper and an electrifying paper as well can be used, by a method wherein, in a recording head having a heating resistance, an electrifying electrode part is mounted at a part of a frictionproof film which covers feed electrodes of the heating resistance. CONSTITUTION:A heating resistance 10 and feed electrodes 11 and 11' are placed on a heat-resistant insulation board 9, such as glass, aluminum, etc., and the work is covered with a hard, antifriction film 12 having a resistivity being approximately similar to that of an insulator, or an electrifying electrode 13, which is caused to have a low-resistance, is mounted at a part of the antifriction film 12 contacting a surface of the feed electrode 11'. When a heat-sensitive sheet is used as a printing sheet 15, it is set so that a signal current flows from a terminal 14' to a terminal 14 through the heating resistance 10, and printing is done by the heat of the heating resistance. When an electrifying sheet is used as the printing sheet 15, it is set so that the signal current flows in a circuit consisting of the terminal 14', the electrodes 11', the electrifying electrodes 13, the electrifying sheet 15, and a grounding metal bar 18, and printing is conducted by the signal curret fed from the electrifying electrode 13. |
