ABSTRACT:
A stylus for entering perforations in a prescored card for the recording of data thereon is disclosed. The perforating end of the stylus includes a conically-shaped center portion positioned within and projecting from a concave-shaped end surface having a sharp edge around the periphery thereof. The scored portion of a card is initially engaged by the sharp cone-shaped tip of the stylus and partially displaced thereby. Continued displacement of the stylus causes the sharp peripheral edge thereof to engage and sever a portion of the card defined by the stylus tip cross section. The sequential and complementary action of the pointed center tip and the sharp-edged periphery of the stylus in engaging the prescored portion of a data card causes the thus engaged portion to be completely severed and displaced from the card in eliminating the need to subsequently wipe the card to remove partially severed chips, or punched portions, therefrom.
