摘要：
In construction of a magnetic encoder used for detection of displacement of a mobile body, a circular magnetized pattern is formed on one longitudinal end face of a magnetic rotary spindle mechanically coupled to the mobile body, and a magnetic sensor faces the magnetized pattern with a prescribed gap. Direct formation of the magnetized pattern on the rotary spindle excludes production errors caused by the conventional coupling process and end-face magnetization assures significant compactness of the entire construction.
