description	A contact displacement meter capable of performing an accurate displacement measurement where a movement speed of a contact is fast and having high resistance property to optical noise. A reference light passing regions are away from each other by a distance of a unique value in a movement scale. A peak position of the reference light passing region at which a received light signal of light passed through the reference light passing region takes a local maxim is detected, and an absolute position of the reference light passing region is specified based on the distance between the adjacent peak positions. A relative position of the reference light passing region with respect to a line sensor is specified based on a received light signal of light passed through a lattice region. A displacement of the contact is calculated based on the specified absolute position and the relative position.
