ABSTRACT:
This invention relates to a precise position device, particularly to such device in which an insensitive zone of an absolute signal consisting of a stepped analog signal formed on the basis of the two-phase incremental position detection signal obtained from an encoder section is eliminated, and an output signal having an approximately linear form may be obtained.
