Abstract
An absolute encoder includes: a scale on which plural marks are arrayed; plural detecting devices each configured to detect a mark group of the plural marks and output a signal corresponding to the mark group; and a processor configured to obtain a coordinate of the scale based on outputs of the detecting devices. The plural marks are arrayed such that a signal obtained by adding plural signals respectively output from the detecting devices includes a periodic signal corresponding to plural periods. The processor obtains first position data based on a magnitude of at least one signal of the plural signals, obtains second position data having a resolution higher than that of the first position data based on a phase of the periodic signal, and generates data representing the coordinate based on the first and second position data.
