Abstract
A conveying device conveys a container including a magnetic body to a target position along a conveyance path and includes a conveyance surface configured by arranging a plurality of magnetic poles including a core and a coil, and including a conveyance path, a drive unit supplying a current to the coil, and a position detection unit estimating the position of the container. The position detection unit excites a first magnetic pole to detect the position of the container and applies a voltage to at least one second magnetic pole that is peripheral in a predetermined range from the first magnetic pole and is different from the first magnetic pole in a direction in which the polarity becomes opposite to the exciting current of the first magnetic pole, and a process of estimating the position of the container based on the current value of the first magnetic pole.
