Abstract:

The patent relates to a level sensing assembly useful in card or document transport systems. Fluid pressure is supplied to various orifices and interact therein. As cards or documents are stacked, the cards interrupt the flow of fluid thereby producing output control signals. Orifices are placed one above the other thereby enabling the output signals to control a lowering, raising or feed device to keep the level of the documents between the orifices or at a predetermined level.
