Abstract
A linear scale type measuring device capable of canceling an error caused by inclination of an encoder, a moire error, is disclosed. A linear encoder disposed relative to a scale includes two sensors A and B which are arranged such that they are inclined at a predetermined angle &thgr; with regard to the scale. At the time of measurement, a detection value corresponding to that with no inclination can be obtained by an operation based on detection values from the sensors A and B, and the known angle &thgr;, even when the encoder is further inclined by any angle &dgr;.
