PURPOSE:To enable the free movement of a thing to be carried in front and rear, right and left direction, mounted on a tip of carrier arm for levitated body levitated by an electro magnet of a carrier main frame by locating the carrier main frame movably in right and left direction and rotatably. CONSTITUTION:Detected signals of position sensors 10a-10d are controlled in feedback, and excited currents of electro magnets 9a-9d of a carrier main frame 3 are controlled so as to keep a levitated body in levitation. In this condition, a motor 13 is driven so as to rotate a pinion 12 and move a carrier 8 of a carrier main frame 3 along the shaft in right and left direction, and a levitated body 1 is moved in an arrow direction (right and left direction) so as to move a thing to be carried b mounted on the tip of a carrying arm 2 in the same direction. On the other hand, a motor 20 is rotated by a predetermined angle and a shaft part 15 is rotated in the arrow port direction so as to rotate the main frame 3. With this rotation, the thing to be carried b on the tip of the carrying arm 2 is rotated by the predetermined angle around the shaft part 15.
