Abstract
Onto a long rectangular board like base board, first Hall IC's are mounted at specified equal pitches in the longitudinal direction, and second Hall IC's are mounted at the equal pitches from a position shifted by a phase difference of 90 degrees in the longitudinal direction relative to this first Hall IC, and a single rectangular board like field magnet (12) having a length of a half of the equal pitch is mounted, opposite to the first Hall IC's and the second hole IC's, and consequently, a linear encoding device is provided, by which a long positional measurement can be performed, and further, which has a simple arrangement.
