Abstract

PURPOSE: To detect absolute line positions in a wide range, by combining the integral of the number of cycles of a detection output signal of a detection object for an origin and current output signals.
CONSTITUTION: Plural detecting parts S1 and S2 which generate electric output signals in prescribed cycles corresponding to mechanical displacement quantities different from each other with respect to the mechanical linear displacement of the detection object and an operating means COM which uses the difference of cycle between detecting parts and output signals of respective detecting parts to obtain the number of cycles from the origin of the detection object to the current position with respect to prescribed one of detecting parts S are provided. The absolute position of the detection object is specified by the combination between the integral of the attained number of cycles and the output signal of the prescribed detecting part S.
