<p>PURPOSE:To obtain a titled long-lived mechanism by fixing a magnet to a rotary member on which an idler is provided, fixing plural coils at a position opposed at a distance from the magnet, and controlling a current of the coil flowing by a power source, by a coil control means. CONSTITUTION:When a permanent magnet 3 is moved in the direction as indicated with an arrow 27, and an idler is brought to an oscillating operation to the left, a left oscillating command signal 25 is inputted to a coil controlling circuit 24, and the coil controlling circuit 24 controls a switch switching circuit 22 and switches a switch 21 as shown in the figure. Therefore, as a coil for flowing a current from plural coils 2, two coils 2 of both sides of the permanent magnet 3 are selected, and to these coils, a current flows in the direction as indicated with an arrow 28 by a power source circuit 23, a magnetic field is generated in the coil 2, an S pole is generated in the coil 2 end of the left side of an N pole of the permanent magnet 3, and an S pole is generated in the coil 2 end of the right side of the S pole. By interaction of this magnetic field and a magnetic field of the permanent magnet 3, magnetic forces of attraction and repulsion are generated in the permanent magnet 3 and the coils of the left side and the right side, respectively, and by these magnetic forces, the permanent magnet 3 is moved in the direction as indicated with the arrow 27.</p> |
