  • Publication number: 20070167887
    Abstract: A massaging device has an applicator driven by a plurality of driving unit to move along two or more different axes to generate a combined massaging action to be applied to the user's body. A controller holds individual speed data each defining a speed at which each of the driving units reciprocates the applicator along each of the different axes, and to control the driving units to reciprocate the applicator in accordance with the associated speed data. The controller controls the speed of the applicator along one of the axes independently from the speed of the applicator moving along another of the axes. Accordingly, the applicator's movements along the different axes can be free from being interfered with each other even being subject to a load, thereby assuring to continue the combined massaging action.
