Expanded Storage Reusable Tabulating Card

A conventional 96-column tabulating card is modified to a 128-column reusable tumble card for entry of up to 64 columns of data during each use.

Card 1 (see A) has two BCD 32-column fields 2,3 at the bottom for receiving up to 64 columns of punched data. Unpunched area 4 is available during the first use of 1 for printing corresponding interpreted data. For reuse, 1 is turned end- for-end face up. Two BCD 32-column fields 5,6 are now at the bottom for receiving up to 64 columns of punched data, and interpreted data is printed in area 7 over previously punched field 3. Card 11 is inexpensive since it is printed on only one side, like a conventional tabulating card; and card curl direction desirably remains the same.

Card 11 (see B) provides two BCD 32-column fields 12, 13 at the bottom of its front face for input of up to 64 columns of punched data and an expanded unpunched area 14 for printing up to 128 columns of interpreted data. For reuse, 11 is turned top-to-bottom upside down. Two BCD 32-column fields 15,16 are now at the bottom for input of up to 64 columns of punched data and up to 128 columns of interpreted data is printed in area 17 over the holes previously punched in areas 12,13.

Card 1 is fed with corner cut at upper left or lower right. Card 11 is fed with corner cut at upper right or lower right. In either case registration is controlled by leading edge, and the card may be reused without confusion since the...
