PURPOSE:To reduce the exchanging frequency of secondary batteries, by providing the secondary batteries with a condenser, and by charging the condenser with the secondary batteries on the stop of the mover. CONSTITUTION:A mover V is provided with secondary batteries E0 feeding power to an electromagnet and a control circuit, and with a condenser E1 to be quickly charged. The mover V is stopped at the specified position of a station ST to start working on mounting a load on, and at the same time, by the working of a solenoid 18, an electrode 16b on the charging equipment side is made to come in contact with an electrode 16a on the mover side, and the condenser E1 is charged in a moment. Then, by a power separator 19, the condenser E1 is kept separated from the secondary batteries E0. As a result, the condenser can be charged with great current in a very short time, namely, in a moment. |
