摘要： A position detector for use in, for example, a robot hand can detect any of a plurality of positions on a movable element. The position detector includes a coding member having a first row of absolute codes and a second row of incremental codes both formed therein in a direction of movement thereof. Positional data in binary codes are serially recorded in the first row whereas regularly formed incremental codes corresponding to respective binary codes are recorded in the second row. The position detector further includes a plurality of light emitting and receiving elements for detecting the codes of the first and second rows and a serial-parallel converter for converting serially detected binary codes of the first row to parallel rows of binary codes based upon detection signals of the second row. The binary codes in each parallel row are equal in number to recording bits of the positional data.
