Claims

[Claims for Utility Model Registration] 1. A system comprising a plurality of optically bright and dark areas at equal pitches formed on the circular circumferential surface of a rotating body that rotates together with a motor shaft, and two or more sets of corresponding light-emitting elements and light-receiving elements. , and those light-receiving elements are arranged so as to receive the light of the corresponding light-emitting elements through the optical bright and dark areas and output signals having a temporal phase difference of equal one interval. A motor equipped with means for detecting speed. 2. The motor according to claim 1, which is a rotor case. 3. The motor according to claim 1 of the utility model registration claim, wherein the optically bright and dark portion is a cut or a hole.
