    摘要: An encoder of the invention comprises: an abnormality detecting circuit for detecting an abnormal state of an encoder main body; and a circuit which inverts a part of output signals of the encoder main body and outputs or does not output a part of the output signals of the encoder main body in response to an abnormality detection signal which is output from the abnormality detecting circuit when the encoder main body is abnormal. Thus, the occurrence of the abnormality of the encoder main body can be detected from the outside.

    摘要: A sequence of random numbers of a desired length is produced using an algorithm for shifting a binary code M bits and adding 0 or 1 so that all produced codes are different from each other. An absolute encoder of a desired resolution is provided using such a sequence of random numbers. Where a slit pattern of M-series random number codes is employed, a circuit for generating a pattern comprising a combination of the M-series random number codes and 0s is employed to provide an absolute encoder having a resolution of 2.sup.k.
