    摘要: A device for recording predetermined magnetization patterns on a magnetic recording medium such as for use in a copying machine. The magnetic medium is first magnetized with a uniform magnetization pattern then passed to a thermal printing head upon which a number of heat generating elements are arranged one-dimensionally on a supporting substrate. The heat generating elements are selectively activated to heat the recording magnetic medium to a temperature greater than the Curie temperature thereof so as to change the direction of the magnetization of the magnetic medium in cooperation with a biasing magnetic field.

    摘要: A copying machine includes an optical sensor of the line scanning type for converting an image into electrical signals, and a thermal recording head controlled in accordance with the image signals. The platen moves with respect to the read unit and the read unit will read in both forward and reverse directions of the platen, and the magnification value can be varied. The total width of energized heating elements and the movement length and speed of the platen may be controlled in accordance with the size of the original. The total number of heating elements energized at any one time is limited, and the machine includes input and output terminals for sending image information externally and for receiving and recording image information other than directly from the read unit.
