PORTABLE CARD PUNCHING APPARATUS

摘要

A PLURALITY OF PRINTED INFORMATION CARDS IDENTIFYING INFORMATIONAL UNITS ARE POSITIONABLE OVER A DATA PROCESSING CARD AND EACH INCLUDES A SLOTTED PORTION CORRESPONDING TO ONE OF THE ROWS OR COLUMNS ON THE CARD TO FACILITATE REGISTRATION OF INFORMATION ON THE DATA CARD BY A CONVENTIONAL STYLUS. The slotted portion of the printed cards are staggered with respect to each other so that as each printed card is positioned over the data card for recording, a different row or column of the data card is exposed. A plastic template having a plurality of perforations corresponding to the scored portions on the data card is positioned over the card for indexing the stylus. A selector card is positioned over the template beneath the printed cards and selectively shields portions of the data card to prevent accidental or undesired recordings. A Styrofoam cleaning base supports the data card to facilitate positive indexing of the stylus and an enclosing container is provided which also aligns the data card, template and selector card into proper registration. The printed cards are hingedly connected to the enclosure to permit rapid and facile registration of each individual card for informational registration. Each card is detachable from the apparatus after it has been used to permit registration of the next card. A reversible mailer is provided to facilitate ease in sending and returning the apparatus through the mails.
