<p>PROBLEM TO BE SOLVED: To make it possible to make a power line or signal line wireless by comprising a means for generating a magnetic field which is disposed in or outside a first apparatus and feeding a power to a second apparatus installed near the first apparatus by the electromagnetic induction of the generated magnetic field. SOLUTION: Only by singly mounting a mobile body 5 on a main body 1, the mobile body 5 receives a magnetic field generated by a magnetic field generating means 2 due to the electromagnetic induction from a host computer 1 through air at a generator 6 wherein the magnetic field energy is converted into an electric energy. The energy received by the generator 6 is transferred to a following stage of a power controller in which the electric energy is accumulated and fed as power voltages to each of elements etc. A communicating part 7 starts an optical communication of memory information in the mobile body 5 which received the power voltages into the main body 1 by the key operation and the communication control in the main body 1 is made at a communication controller 3.</p> |
