    摘要： An absolute position detection encoder includes a coder having a track provided with first graduations of an absolute pattern and second graduations of an incremental pattern, plural sensors movable relative to the coder along the longitudinal direction of the track, and a signal processing circuit for processing detection pulse trains, obtained upon reading the first graduations by the sensors, in synchronism with the time point corresponding to approximately the mid position of the minimum reading unit of the first graduation. The encoder outputs the relative position between the coder and the sensors in the form of parallel code signals as the absolute position read out from the absolute pattern graduations on the coder. By detecting the absolute pattern in synchronism with the time point corresponding to substantially the middle of the minimum reading unit of the first graduations, an absolute position detection signal of the correct code contents free of readout errors may be taken out for both the forward and reverse directions of the relative movement. On account of the signal selection function by the binary repetitive rectangular signal obtained from the incremental pattern reading results, the absolute position detection signal of the correct code contents may be taken out simultaneously with turn-on of the power source. The binary repetitive rectangular signal may also be used for generating a sub-scale signal for substantially improving the resolving power.

    摘要： An absolute encoder having a coder in which an incremental pattern and an absolute pattern are arranged in parallel and a detector including sensors for detecting the incremental pattern and the absolute pattern respectively. The absolute encoder comprises a discriminater to discriminate a relative phase position of the coder and the detector in one pitch of the incremental pattern from an output of the sensor for detecting the incremental pattern, and a signal generator to generate a synchronizing signal when a discriminated phase position coincides with a predetemined phase position by means of an electric circuit in one pitch of the incremental pattern. The absolute pattern is read on the basis of the synchronizing signal at a position except for the boundary region between the minimum reading units.
