Abstract: To provide a tapping device, capable of making a more comfortable tapping motion. A tapping device for vertically tapping a skin surface comprising: a tapping applicator for applying a normal force on the skin surface, wherein the tapping applicator is reciprocated in a direction perpendicular to the skin surface; an actuator for generating the linear reciprocating motion of the tapping applicator, wherein the actuator comprises a direct-current motor which is driven at an applied magnitude of voltage; a pressure sensing mechanism for measuring the magnitude of normal pressure exerted on the actuator during the operation of the tapping device in real time; and a controller for controlling the magnitude of voltage to be applied to the direct-current motor in real time, wherein the applied magnitude of voltage corresponds to the magnitude of normal pressure measured by the pressure sensing mechanism.
