Abstract: A rotary encoder has a disc, a pair of photo-interrupters, an adjusting member, and a shifting controller. The disc rotates around a rotating axis and has slits that are formed circumferentially at given intervals. Each of the photo-interrupters has a light-emitting device and a photo-detecting device opposite one another, and generates two signals with a phase difference.

The adjusting member contacts the pair of photo-interrupters, and is movable along a shifting direction corresponding to a radial direction of the disc, so as to press the pair of photo-interrupters. The adjusting member adjusts a relative position-relationship between the pair of photo-interrupters associated with the phase difference.
