Abstract
A device for measuring displacement comprises a pair of sensor elements of which output voltage changes stepwise in dependency upon displacement of a measurement object, a differentiating circuit for detecting time points at which the output voltage of the pair of sensor elements suddenly changes, and a counter for counting the sudden change time points of the output voltage detected by the differentiating curcuit.
