Abstract / Hauptanspruch
An inductive detection encoder according to the present invention includes: first and second members which are oppositely disposed so as to relatively move in a measurement direction; a transmitting coil formed in the first member; a magnetic flux coupled body which is formed in the second member and coupled with a magnetic field generated by the transmitting coil; and a receiving coil formed in the first member and having receiving loops. At least one of the transmitting coil and the receiving coil has a specific pattern that impairs the uniformity and periodicity of a pattern; and a dummy pattern formed in a position corresponding to a specific phase relationship of a cycle generated by the track with respect to the specific pattern.
