Abstract
An absolute position detection device includes: a scale unit having a first member and disposed on a mover or a stator; a sensor unit having detection elements disposed at a first interval to detect position correspondence information corresponding to the first member; and a computation unit that: detects a distortion boundary position of output based on a comparison result between the position correspondence information by first and second detection elements; based on element coordinates of either the first or second detection element, element coordinates of a third detection element, the first interval, a length of the output pairs, and the position correspondence information by the third detection element, calculates a position of the third detection element to an end position of the first member; and calculates a positional relationship between the mover and the stator based on the calculated position and a length of the first member.
