Also in this case, the rotational force generated on the disk 10 is the same as that described above, and a stronger rotational force is generated due to the magnetic force of the rows of the magnets 12 on the disk 10 side.

Since 4 is separated from the surface of the disk 10, the suction force is reduced, but since the undulating arm 13 rotates upward about the shaft 14, the position of the drive-side magnet 24 is changed to “first position”. It is displaced inward of the disc 10 from the "position".

Since the two magnets 2 are arranged in a circular arc shape, the drive magnets 24 that have moved upward from the “first position” that is close to and immediately above the magnet 12 row and that are displaced inwardly of the disk 10 are Not only the magnetic field but also the magnetic force from the other plural magnets 12 that are sequentially adjacent to each other act to compensate for the decrease in the attractive force.

Since it is smaller than the distance r1 in FIG. 6, a large amount of torque is required to rotate the disc 10, and conversely, the torque can be small at the “outer third position” in FIG.
