Claim 1:
2. The lifting and lowering transportation device according to claim 1, wherein
the lifting and lowering platform included in each of the transportation units includes:
a rotor rotatable around an axis in a vertical direction; and
a transporter driven by the rotation of the rotor to transport the article for delivery;

lifting and lowering platform stators are provided corresponding to the plurality of delivery positions;
each of the lifting and lowering platform stators has a hollow shape;
an inner space of each of the lifting and lowering platform stators is open to outside at both ends of a vertical direction of the lifting and lowering platform stators;
each of the lifting and lowering platform stators includes an opening that opens the inner space to the outside in a horizontal direction, connecting open portions at both ends in the vertical direction;
when the lifting and lowering platform is at any of the plurality of delivery positions, the lifting and lowering platform stator at the delivery position is positioned so that the lifting and lowering platform stator is not in contact with and surrounds the rotor in the lifting and lowering platform; and
the lifting and lowering platform stator drives the rotor in a non-contact manner by generating a magnetic effect while surrounding the rotor.
