Abstract: An integrated self service package pick up and drop off system which is particularly suitable for retail dry cleaning operations is described. A fully enclosed cabinet contains a customer drop off chute, and a customer pick up door which are computer controlled in response to customer signals. Inside the cabinet, which can be entered only by an authorized attendant, to remove dropped off orders and load complete orders, there is provided a motorized gantry system which can select and remove an individual customers order from bar coded storage rails and transport the order down the central aisle to the customer pickup point for removal from the cabinet.
