Abstract
A movable member is moved in a preset direction in a linear motor. A characteristic-change position-detecting unit detects a position where the magnetic characteristic of the magnets has abruptly changed. The position detected is used as an origin-setting reference position. A reference position for the absolute position of the magnetic linear encoder is set based on the reference position.
