  • the cross-sectional shape can move by its own weight toward the lower end of the guide groove 13b, for example, the cross-section may be a flat inclined surface that is inclined acutely with respect to the left surfaces of the right plates 13 and 13-1. The same effect as described above can be obtained.
  • the number of permanent magnets 40d provided in the rotor 40 is related to the rotational speed of the rotor 40, but the number of permanent magnets 40d is preferably 4 to 16 in order to accurately perform the above-described supply operation. Further, the angular intervals of the permanent magnets 40d do not have to be equal, but it is easier to control the rotation of the rotor 40 in the supply operation when the intervals are equal. Even if this rotor 40-1 or the bulk feeder using the rotor 40-2 in place of the rotor 40 is used, the same supply operation as described above can be realized and the same effect as described above can be obtained.
  • the permanent magnet 40d uses a shape other than the columnar shape. Also good.
  • the rotor 40-2 shown in FIG. 23B uses a quadrangular prism as the permanent magnet 40d ', and the center of one magnetic pole of each permanent magnet 40d' coincides with the permanent magnet 40d.
  • it is possible to use a triangular prism or a polygonal prism having five or more corners as each permanent magnet it is preferable to use a cylinder or a quadrangular prism in view of the component cost of the permanent magnet. Even if it is a bulk feeder using this rotor 40-3 instead of the rotor 40, the same supply operation as described above can be realized, and the same effect as described above can be obtained.
