ABSTRACT:
A data control device for use in recording sales transactions in regard to one or more different items which are subject to various classifications. The device includes data input registers, each of which stores a preset value for a particular item, and a data register into which a desired value for an item not frequently encountered may be entered on a manual keyboard. Selected data from the input registers are successively added and stored in an accumulator except when the keyboard is activated, whereupon data entered on the keyboard is added to the contents of the accumulator.
