PURPOSE:To provide a conveying apparatus comprising a lot of electromagnets disposed below the top face plate along a transport path for a transported article, which can smoothly transport the transported article on the top face plate along a designated path by magnetic attraction of a permanent magnet fixed to the transported article and the electromagnets. CONSTITUTION:Air is jetted out above the top face plate 1 through a lot of air holes 2 disposed on the top face plate 1, thereby to slightly float a transported article 5 placed on the plate. In such floating state, an electric current is applied to a lot of electromagnets (a)-(m) disposed below the top face plate 1 along a moving path of the transported article 5. Further, the magnitude of the electric current and each polarity of the electromagnets (a)-(m) are changed to magnetically attract and repulse a permanent magnet 7 fixed to the transported article to and from the electromagnets, whereby the transported article is moved along a designated path in such a manner as to slide on the top face plate 1. |
