Abstract:
An encoder, which measures a relative moving amount of a second member relative to a first member, includes: a diffraction grating provided on the first member; a light-incident optical member causing a measuring light to come into a grating pattern surface of the diffraction grating substantially perpendicularly; a first reflecting member provided on the second member and reflecting a diffracted light generated from the diffraction grating; a first direction-changing member changing a direction of the diffracted light; a first photo-detector detecting an interference light generated by interference between a double diffracted light and other diffracted light than the double diffracted light or a reference light, the double diffracted light being generated, via diffraction of the diffracted light, from the diffraction grating; and a measuring section which obtains the relative moving amount of the second member relative to the first member by using a detection signal from the first photo-detector.

Claim (Index 9):
The encoder device according to  claim 8 , further comprising a calculator configured to calculate the relative moving amount between the first member and the second member along the first and second directions by using outputs from the first, second, third and fourth photo-detectors.
