Abstract
A position detector includes a position detection magnet unit installed at each of a plurality of carriers, and a position detection unit. The position detection magnet unit includes a plurality of magnets disposed such that different magnetic poles are arranged alternately in a transport direction of the carriers, and side magnetic shielding portions installed at the ends of the position detection magnet unit. The position detection unit includes: a processing substrate disposed in parallel to the transport direction of the carriers; a plurality of magnetic detection elements disposed side by side in the transport direction of the carriers on a front side of the processing substrate; and a substrate-side magnetic shielding portion opposite the magnetic detection elements, the substrate-side magnetic shielding portion being installed on a back side of the processing substrate.
