ABSTRACT:
A card guideway frame is movable in the width direction of a card to select the column in which a hole is to be punched and the card insertion depth is variable to determine the spacing between the bottom edge of the card and the hole. The insertion depth is set by a stop passing through the wide aperture of the guideway frame and a carriage resting on a projection of the stop and movable along the length of the guideway frame with the stop carries a pair of guide plates having a narrow slit between them for the card and practically filling the aperture in the frame, so as to constrain the card into a flat shape, correcting any arching and resisting any bending from insertion forces, even though the frame restrains only the extreme edges of the card at the sides of the working area. The carriage also carries a check stop which allows the card to be inserted all the way to the insertion depth control only if the card is presented with a cut corner at the correct side of the bottom edge and in that case an electrical contact is provided to initiate the punching operation.
