<P>PROBLEM TO BE SOLVED: To provide a self-traveling door that can be fed electrically in a state whichever closed or opened. <P>SOLUTION: An electrical supply source is connected to a primary coil arranged on a fixed side such as a column or a wall toward the door. A full closing secondary coil for electromagnetic coupling to the primary coil is arranged on the door so as to be opposed to the primary coil when the door is fully closed, and a full opening secondary coil for electromagnetic coupling to the primary coil is arranged on the door so as to be opposed to the primary coil when the door is fully opened. A switch circuit for connecting either secondary coil to a voltage stabilizer in dependence on full closing or full opening of the door is disposed in the door. A battery supplied with electricity via the voltage stabilizer circuit is disposed in the door. The battery is connected to a door controller. <P>COPYRIGHT: (C)2004,JPO |
