Abstract

A rotary encoder for detecting the angle of rotation of a first rotatable shaft, with a first mark which is coupled with the first shaft, a second mark which is coupled with the second rotatable shaft, a third mark which is coupled with the second shaft, a fixed fourth mark and means for detecting a passage of the third mark though a vicinity of the fourth mark and means for detecting a coincidence of the angles of rotation of the first and the second marks.
