Reference numeral 3 denotes a transport belt drive motor. Reference numeral 14 denotes a nonmagnetic belt receiver. The transport device 10 has a first magnet 21 disposed at a lower position along an article moving path by the transport belt 11 and a second magnet 22 provided on the article 12.
The second magnet 22 may be directly built in the article 12 itself, or may be indirectly attached to the article 12 such as a transport case for the article 12.

The first magnet 21 has two flat magnets 21.
A and 21B (see FIG. 2 (A)), and these divided magnets 21A and 21B are arranged close to each other with a gap therebetween.

The second magnet 22 is constituted by one plate-like magnet. Then, the first and second magnets 21 and 22
The magnetic poles that can attract each other can face each other via the conveyor belt 11. That is, the first magnet 21 sets the N pole to the second
, And the second magnet 22 can face the S pole to the first magnet 21.

Further, at a position below the article moving path by the conveyor belt 11 and upstream of the first magnet 21,
An article guiding magnet 23 composed of a plurality of plate-shaped magnets is spaced apart. The article guiding magnet 23 can face the N pole to the second magnet 22, so that the second magnet 22 on the article 12 side relatively passes over the first magnet 21. Exerts a magnetic attraction action on the second magnet 22 to produce the article 1
Correct the movement trajectory of No. 2. The article guiding magnet 23 is
