    摘要: In a triple slit optical encoder, a first grating and a third grating are formed on separate members, and values of a first effective width W1 and a first pitch p1 of an optical pattern on the first grating, and a third effective width W3 and a third pitch p3 of an optical pattern on the third grating are set to values such that a periodic signal having the amplitude effective for detection of a relative displacement of a scale is achieved based on periodicity of the self-image, refractive indices of substances of substances and/or spaces interposed in the optical path from a bare LED up to a photodetector, and the thickness of those substances and/or spaces in a direction substantially perpendicular to a plane on which the second grating is formed.

    摘要: 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.

    摘要: 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.
