At a franking or imprinting station in a point-of-sale terminal printer, either a continuous web of receipt paper or separately-inserted individual sheets of documents, such as checks or charge slips, may be entered for printing. The mechanism shown in the figure illustrates, in an end elevation view, the main components of such a printing station. A stop gate is required to block the entry of documents being inserted by hand when the mechanism is engaged to feed the continuous web form receipt paper. This design automatically retracts the gate when the mechanism is in the proper position for feeding an individual document, not the receipt paper.
