The door includes first and second ends and an underside portion. The apparatus also includes structures for selectively moving the door between its escrow, acceptance, and return positions, including: (a) guide elements for guiding the door for pivotal movement in a first direction and in a second direction opposite to the first direction; (b) a pivotal support element positioned below the door and having an upper portion engaging the underside of the door intermediate the first and second ends of the door, the pivotal support element pivoting about a pivot axis below the door; and (c) an actuator for pivoting the pivotal support element.
