番地型位置検出器。 A code plate is attached to the detected object and has codes representing absolute addresses arranged along the direction of movement of the object, and the code on the code plate is read so that the least significant bit code in the code corresponds to the least significant bit code. A reading device that outputs a plurality of least significant bit analog signals with different phases, and a plurality of least significant bit analog signals with different phases from the reading device are each compared with a predetermined threshold value to determine the phase or pulse width. a comparator that converts at least one of the above into a different digital signal, and a code that encodes the digital signal from the comparator into a code that divides and displays one absolute address represented by the code on the code plate by logic conversion and outputs the code. An absolute address type position detector characterized by comprising a conversion circuit.
