Reflection type encoder, scale thereof and method for producing scale










Image Number 8 for United States Patent #8127993.

A reflection type encoder, which receives a plurality of light-receiving signals from a single scale, includes a light source, a scale having a plurality of patterns formed thereon to which light is irradiated from the light source, and a light-receiving element for receiving light reflected from each of the plurality of patterns, wherein a plurality of patterns each having different thicknesses are formed on a single track of the scale by using a dielectric substance, light of a plurality of wavelengths each having different brightnesses in accordance with differences in the thickness of the dielectric substance is irradiated from the light source, and a light-receiving signal is obtained for the respective thicknesses of the dielectric substance. Therefore, the scale can be downsized by overlapping a plurality of patterns on the same track.
