<p>PURPOSE:To prevent a crash from being generated by stopping a driving section with a contact sensor before positioning projections on the side of feed current come in contact with the side of an unattended vehicle. CONSTITUTION:When an unattended vehicle 1 is confronted with a feed current coupler 4 in order to feed current and comes to a position confronted with positioning projections 4a, 4b, then the unattended vehicle 1 is stopped. In this case, the stop position of the unattended vehicle 1 is exactly determined, and when the positioning projections 4a, 4b are inserted into positioning holes 3a, 3b, then incoming terminals 3c, 3d and feed current terminals 4c, 4d are connected to each other, and normal charging is performed. When positioning precision is poor, then a bar-shaped member 7 cannot be inserted into a penetration hole 9, and a contact sensor 8 comes in contact with the external surface of a feed current means 3, and the contact sensor 8 is worked, and the working of a driving gear 6 is stopped, and the feed current coupler 4 is stopped for emergency.</p> |
