Abstract
A control device controls travel direction of a traveling body that travels along a plurality of magnetic markers arranged with intervals therebetween on a track, the control device including: a first sensor for detecting the magnetic markers; a second sensor for detecting speed or acceleration; a first lateral position calculation unit for calculating a lateral position of the traveling body by a detection result from the first sensor, when the first sensor has detected a magnetic marker; a second lateral position calculation unit for calculating a lateral position of the traveling body by a detection result from the second sensor, when the first sensor is not detecting a magnetic marker; and a travel direction control unit for controlling the travel direction of the traveling body by the lateral position of the traveling body as calculated by the first lateral position calculation unit or the second lateral position calculation unit.
