ABSTRACT:
An encoder or an information reading device detects a scale with a probe that is vibrated at a predetermined frequency and amplitude in a predetermined direction. The angular positional relationship between the direction of probe vibration and the scale is detected according to frequency spectrum information of a detection signal obtained by detecting the scale with the vibrating probe.
