CARDHOLDING PLATEN OPERATIONAL THEORY
The purpose of the cardholding platen is to keep cards from slipping while being typed on. The blade of the cardholding platen has a groove under both sides to allow a card to be held by either the top or the bottom. A card stop mounted on the blade can be moved to help in positioning the card laterally in the card slot (Figure 1).
