ABSTRACT:
Linear sensors are provided in two rows along a moving route of a moving body. A relative position of a magnet provided in the moving body relative to the linear sensor is determined, and an origin coordinate of the linear sensor is added to the determined relative position to determine an absolute position of the moving body.
