<p>Provided is a noncontact power feed system which can prevent operation of a wireless mouse from being disabled due to the fact that the wireless mouse is out of a mouse pad area where power can be fed and that power cannot be fed. In the noncontact power feed system for a wireless mouse, a mouse pad is provided with a position detecting means for detecting a position of the wireless mouse on the mouse pad; a plurality of power feed coils arranged on an operation surface of the mouse pad; a power feed selecting means which selects at least one power feed coil which corresponds to the wireless mouse position detected by the position detecting means from among the power feed coils; and a power feed means which feeds power to be fed to the power feed coil selected by the power feed selecting means. The wireless mouse is provided with a first storage means which stores induction power obtained by electromagnetic induction between the selected power feed coil and a power receiving coil in an electric double layer capacitor.</p> |
