９を中心に磁気ヘツド７を揺動させる。Effects In this invention, the protruding coil terminals and the support frame are placed apart from each other on both sides of the coil, so the conductor for applying voltage to the coil is lifted from the coil, and the coil is moved. In this case, the conductor and the coil will not interfere with each other and cause any adverse effects. Furthermore, since the coil terminal and the support frame are placed near the part where the arm is attached on the side facing the permanent magnet, which is wider than the other end, the coil terminal and the support frame are It becomes possible to arrange them separately on both sides of the coil. Specifically, when a voltage is applied to the terminal 6 of the coil via the conducting wire 10, the moving coil 3 receives a force and moves between it and the magnetic circuit generated in the E-shaped yoke according to Fleming's left hand rule. The movement causes the magnetic head 7 to swing around the support shaft 9 of the arm.

けることがない。 The terminal 6 of the moving coil 3 and the support frame 11 for the conductor are as follows:
Since the conducting wire 10 protrudes from the cylindrical bobbin 4 of the coil, the conducting wire 10 does not interfere with the moving coil 3 while the moving coil is moving. Therefore, the moving coil 3 is operated only by the applied voltage and is not affected by other adverse effects.
