tabulator
A punch card accounting machine that calculates totals and prints the results. Since the late 1800s, tabulators were used to accumulate totals and were later capable of printing. Countless invoices, checks and green-striped reports were printed on tabulating machines all the way up into the 1970s. See Hollerith machine and punch card.

| The U.S. census of 1890 was counted on tabulating machines designed by Herman Hollerith (on the wall). The card was placed in the reader, the handle was pulled down, and the data was tabulated on the dials. Then the appropriate lid opened up on the sorting box, and the punch card was dropped in.
