Abstract
PURPOSE:To save a magnetic pole body constituent material and to reduce the size of the rotary encoder by providing magnetic tracks on one surface of a discoid magnetic pole body. CONSTITUTION:The eight annular magnetic tracks H7-H0 are provided on one surface 6a of the discoid encoder substrate 6 made of a plastic magnet concentrically with the axis Y-Y. All of the magnetic tracks H7-H0 have magnetic poles S and N magnetized alternately, and magnetic poles belonging the same magnetic track are at the same angle to the axis Y-Y. The rotary encoder 7 is provided which consists of a rotary shaft 2 and a magnetic detector 3. A signal processing part 8 performs specific signal processing as to voltage signals E0 outputted by the eight detecting elements 34 to make a display corresponding to the rotational position of the rotary shaft.
