There is provided a displacement measuring device that minimize unnecessary power consumption and improves power efficiency. A displacement measuring device includes a main scale and a detection head that is provided in such a manner as to be relatively displaceable to the main scale and outputs a periodic signal having a phase to be changed according to relative displacement to the main scale.
