Abstract:
1. A massaging device comprising: a base; an applicator which is movably supported to said base, said applicator being configured to come into contact with a part of a human body such as a back; at least two driving units which drive said applicator, said at least two driving units being configured to cause said applicator to make different reciprocating movements, respectively in different directions from each other relative to said human body, thereby applying a composite massaging force thereto; a controller configured to control said at least two driving units for reciprocating said applicator in different directions, thereby providing said massaging force to the user selectively in one of different massaging patterns which are defined by combinations of said reciprocating directions; sensor means configured to detect current positions of said applicator respectively with regard to said different directions; and a coordinator included in said controller and being configured to shift by a time period a phase of a first reciprocating movement of said applicator relative to a phase of a second reciprocating movement of said applicator, wherein said shift of said time period is of a duration within said phase of said second reciprocating movement.
