Abstract
Provided is a control device capable of reducing cost and thickness by using an electromagnetic actuator, and capable of efficiently generating a thrust suitable for a haptic feeling feedback to an operator who touches and operates thereto. The control device controls the electromagnetic actuator that drives an operation device supported to be elastically vibrated in one direction of a vibrating direction thereof; includes a current pulse supply unit configured to supply a plurality of drive current pulses to a coil of the electromagnetic actuator as a drive current for driving the operation device in response to a touch operation of the operation device; and an interval between peaks for each of the drive current pulses is in a range of ½ times to 1 times a vibration period of an elastic vibration.
