In [1]we considered singular integral operators with orientation-reversing shift on the space L2 over the real line and piecewise coecients having at most four dierent values; conditions of the invertibility of the operators were found. In this article we consider singular integral operators with orientation-preserving shift on the space L2 over the unit circle and coecients of a special structure having automorphic properties; conditions of the invertibility of the operators are obtained.
