Abstract
Abstract A personal check accounting unit includes an alphanumeric keyboard for entry of transaction data including an alphabetic portion and a numeric portion. The transaction data is stored and a calculator unit responds to the numeric portions to operate thereon to compute balance data. A memory receives and stores the output from the calculator, and print means is actuated in response to entry of the alphanumeric data for printing a verification thereof along with the contents of the memory. In one aspect, a check pack holder is attached to the printer, and an electrical storage unit in the pack powers the print means to print the quantity of checks in the pack.
