Abstract
A photoelectric encoder includes a scale in which diffraction gratings are formed at predetermined pitches in a measurement axis direction, a detection head which is relatively movable with respect to the scale, and which includes an illuminating portion configured to illuminate the scale, and a light receiving portion configured to receive light reflected by or transmitted through the diffraction gratings of the scale, a signal processing device configured to process a light reception signal output from the light receiving portion of the detection head, and a signal transmitting unit configured to transmit a signal between the detection head and the signal processing device. The signal processing device includes a display unit configured to display information indicating an attachment posture of the detection head with respect to the scale.
