Abstract
An encoder includes a scale, a detector, and a processor. The processor executes a second process while executing a first process, calculates a first relative position of one of the scale and the detector to the other of the scale and the detector when a calculation of a relative position between them starts, and then calculates a second relative position of the one to the other based on a relative displacement amount between them and the first relative position.
