PURPOSE:To make the recording pressure of a pen variable by varying the excitation of a coil provided between a pen recording section and a magnetic substrate on which a recording paper is arranged. CONSTITUTION:A recording paper 4 is placed on a substrate 8 made of a magnetic material and then faces a yoke 7 around which an exciting coil 2 is wound. a pen 6 is provided in a space in the center of the yoke 7 in such a manner that the tip 6b thereof can move to the paper 4. With a change in the excitation force of an excitation coil, the pressure working between the magnetic substrate and the recording pen varys corresponding thereto. |
