<p><P>PROBLEM TO BE SOLVED: To achieve connection of a plurality of transmission electrodes displaced on a floor surface with a power supply, in accordance with a power supply demand signal supplied from receiving electrodes on an on-floor object, to supply electric power to the on-floor object with no cord, with high safety, and without the risk of electricity leakages, short circuitings, or electrification, by making the on-floor object recognize the positions of the transmission electrodes, to facilitate manufacture of a power supply floor at low cost, by reducing the number of transmission electrodes. <P>SOLUTION: The plurality of feeding electrodes 3, provided on the floor surface 2, are set so as to be individually switched at an under-floor wiring 15 by a selector 4. A sensor 33 which detects positions to the feeding electrodes 3 is provided at the on-floor object 19 from the power supply floor 1, in which the feeding electrodes 3 are connected with a power line 16 corresponding to the power supply demand signal H3 in which the selector 4 is applied from the on-floor object 19 to predict and determine the targeted position of the feeding electrodes 3, and to completely obtain contact between the receiving electrodes 24 and the feeding electrodes 3, thus obtaining power supply to the on-floor object 19. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
