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.
