Abstract: A loading/unloading apparatus used in conjunction with stations from which or to which objects are loaded or unloaded. The loading/unloading apparatus includes a pickup/receiving member which is used in the transfer of objects to and from the stations. The pickup/receiving member includes one or more driven roller elements which are arranged close to an end of the pickup receiving member and which are utilized in the transfer of the object either to or from the station. The loading/unloading apparatus also includes moving devices for moving the pickup/receiving member in a translational direction along a longitudinal axis of the pickup member either towards or away from the station. The loading/unloading apparatus is particularly adapted for use with passive loading/unloading stations which are not provided with electrical power.
