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 scale for a photoelectric encoder includes a scale substrate and a reflection film formed at a predetermined pitch on the scale substrate. A surface of the reflection film forms a reflection surface. A low-reflection surface is formed by etching the scale substrate between reflection films. Accordingly, a scale can be provided which is lower in cost and has favorable yield rates.
