Abstract: An optical encoder is a reflecting triple grating type optical encoder. A light projecting section of the optical encoder which includes a combination of a bare chip LED and a first grating of a first pitch p1, irradiates a predetermined light. A photodetecting section of the optical encoder which includes a combination of a photodetector and a third grating of a third pitch p3 detects a movement of a self image. Each of the first grating and the third grating is disposed substantially parallel with respect to a scale, and a substantially parallel and substantially flat light transmitting area is formed in a predetermined portion of a surface of a detecting head. A light transparent member is disposed in a space between the surface of the detecting head, and the first grating and the second grating.

Abstract: A plurality of analog signals are detected in a sensor in accordance with a displacement of a scale on which a pattern with a predetermined cycle is formed. The plurality of analog signals are subjected to signal processing in a signal processing portion, and then output from a sensor head. Setup switching is performed by a setup switching portion provided in the sensor head in such a manner that an output signal at this moment complies with a signal input specification of a positional information output device. Further, the sensor, the signal processing portion and the setup switching portion form an integrated circuit.

Abstract: An optical encoder comprises a sensor head including a light source and a photodetector and a scale that moves relative to the sensor head. The light emitted from the light source is reflected, transmitted or diffracted by the scale, and the reflected, transmitted or diffracted light is received by the photodetector to allow the sensor head to output a displacement signal. The sensor head includes a wiring substrate having electrodes formed thereon and on which the light source and photodetector are disposed at predetermined positions and a light transmitting material that covers the wiring substrate, light source, and photodetector. A side plane obtained by cutting the wiring substrate and light transmitting material at the same time in the direction substantially perpendicular to the light receiving surface of the photodetector serves as a reference position related to disposition of the components to be mounted on the wiring substrate.
