The movable part includes a transmitting means for converting the electrical signal output by the optical sensor into an optical signal and transmitting the same, and the fixed part receives the optical signal from the transmitting means and restores it to an electrical signal. A linear scale, characterized in that it comprises a receiving means for processing to detect the amount of relative displacement between the scale and the optical sensor.
