Abstract: A linear encoder includes a plate-type scale and a head which moves along the longitudinal direction of the scale. The scale has graduations formed on a surface of the scale and arranged along the longitudinal direction of the scale. The head includes a reading part which detects an amount of a relative movement of the head with respect to the scale by reading graduations formed on the scale. The head includes four bearings each having a rotation axis extending along the transverse direction of the scale. Each of the bearings is situated on the head so as to abut against a surface of the scale, to function as a spacer to maintain a distance between the scale and the head. The scale acts as a plate member interposed between the reading part and the graduations.

Abstract: An induction type position measuring apparatus includes a scale and a sensor. The scale includes a track having a plurality of control patterns provided at equal intervals along a measurement reference line to control flow of an induced current, and a first edge portion and a second edge portion located on both sides of the measurement reference line. The sensor is provided to be capable of moving relatively to the scale along the measurement reference line to detect an induced current. The scale includes regulation patterns at least between the track and the first edge portion or between the track and the second edge portion to regulate a flow of an induced current.

Abstract: A micrometer includes: a frame; an anvil; a spindle; an encoder; a display; a strain gauge that detects a deformation of the frame; a storage that stores a change amount of the detection value (a displacement of the spindle detected by the encoder) per a unit deformation detected by the strain gauge, as a compensation factor; and a compensator that compensates the detection value based on a difference between a zeroset-time deformation that is detected by the strain gauge when a command for zeroset is given and a measurement-time deformation that is detected by the strain gauge in measurement, and based on the compensation factor stored in the storage.
