    摘要: An optical encoder (100) is provided with: a light-emitting element (30) including a main-signal light-emitting element (31) having a red LED (31A) that emits red light and an origin light-emitting element (32) having an infrared LED (32A) that emits infrared light; and a receiver unit (40) including a main-signal photo detector (41) that receives the red light to generate a predetermined signal and an origin photo detector (42) that receives the infrared light to generate a predetermined signal. Accordingly, even when the infrared light enters the main-signal photo detector (41) or the red light enters the origin photo detector (42), no signal is generated by the light, thereby effectively preventing crosstalk. Thus, the measurement accuracy of the optical encoder (100) can be improved.

    摘要: An optical encoder which is designed to convert light generated from a light source into parallel light rays by using a collimator lens, thereby allowing the collimated light to radiate to gratings (a first grating, a second grating and a third grating). A diffusing element (a diffusion plate or a diffusion surface) is provided between the light source and the collimator lens to mitigate the parallelization degree of light, thereby weakening the second-order and the third-order or high-order diffraction light. Consequently, even where a light emitting diode (LED) or laser diode (LD) is used as the light source, a favorable interference output can be obtained.

    摘要: In an optical encoder which is designed to convert light generated from a light source into parallel light rays by using a collimator lens, thereby allowing the collimated light to radiate to gratings (a first grating, a second grating and a third grating), a diffusion means (a diffusion plate or a diffusion surface) is provided between the light source and the collimator lens to mitigate the parallelization degree of light, thereby weakening the second-order and the third-order or high-order diffraction light. Thereby, even where a light emitting diode (LED) or laser diode (LD) is used as the light source, a favorable interference output can be obtained.

    摘要: When generating an origin signal of an encoder having a scale on which an incremental pattern and the origin pattern are formed, an origin signal having a necessary position and width is generated by software based on an origin waveform obtained from the origin pattern. This enables origin detection with excellent repeatability, S/N ratio (pulse width), and bidirectionality while maintaining ease of mounting and adjustment.

    摘要: A main scale is firmly bonded to a metal tape having a desired coefficient of linear expansion by a powerful adhesive. At the same time, the metal tape is fixed to a frame by a two-sided adhesive tape so as to be capable of expansion and contraction. A length measuring apparatus is provided, wherein a scale material which is unstable with respect to variations in temperature and humidity is stabilized, thereby achieving a desired coefficient of linear expansion.
