<p>PURPOSE:To improve the efficiency of operation of an unmanned cart by mounting a feed section at the position of stop of the unmanned cart while a power receiving section connective and detachable to the feed section is fitted to the unmanned cart. CONSTITUTION:When an unmanned cart 2 is stopped at the position of stop, terminals 31 for a power receiving section 3 fall as shown in the downward arrow during the stopping time of the unmanned cart. When the terminals 31 are connected to power terminals 21 for a feed section 2, charge to a battery 33 is started. Charge to the battery 33 is limited within the time when the unmanned cart 1 is stopped. Accordingly, the efficiency of operation of the unmanned cart can be improved.</p> |
