Abstract
There is provided a displacement measuring apparatus capable of reducing power consumption in a sleep mode. An operation mode of a signal processing unit includes a measurement operation execution mode to calculate a displacement or position as a measurement value using a sensor signal from a displacement sensor, and a sleep mode to reduce power consumption compared to the measurement operation execution mode. In the sleep mode, the signal processing unit performs a substitute calculation process at a predetermined sampling frequency to calculate a substitute value related to the displacement or position using fewer sensor signals than in the measurement operation execution mode. The operation-mode control unit assumes that a variation of the displacement sensor has been detected when there is a variation in the substitute value, cancels the sleep mode, and switches the signal processing unit to the measurement operation execution mode.
