Patent number: 7892192Abstract: A massaging device having 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.Type: GrantFiled: January 16, 2007Date of Patent: February 22, 2011Assignee: Panasonic Electric Works Co., Ltd.Inventors: Daisuke Tsukada, Motoharu Muto, Takayoshi Tanizawa, Satoshi Kajiyama, Masamichi Miyaguchi, Hiroyuki Inoue, Masatoshi Dairin, Munekiyo Ikebe, Yoshiharu Hayashi, Masaki Nagano, Takashi Yukawa
