Abstract: An electronic cash register inhibits registration of information associated with a commodity unless an operator code comprised of a plurality of digits and identifying an operator is inputted. A preset code further allows selection of the manner of indicating and printing the inputted operator code. When an operator code comprised of a plurality of digits is entered by operating a decimal keyboard or ten-key (1) and an operator code key and when a first mode is set through a mode selection key (7), all the digits of the operator code are displayed in a display (11) and printed in a printer (12). If and when a second mode is set, only a predetermined partial digit or digits of the operator code comprised of a plurality of digits are printed and none of digits are displayed. If a third mode is set, both displaying and printing of the operator code are inhibited. Thus, a user can arbitrarily select whether the operator code should be displayed and printed, by switching the mode.

Abstract: An electronic cash register includes a mode selector for selecting a registration mode or a check and adjustment mode. The memories for the storage of various sales are adjusted during the check and adjustment mode to correct errors. The pre-adjustment information is retained until a clear operation is selected by the operator. A machine-locked condition is established in response to the adjustment operation. In response to the machine-locked condition any key input other than those used during the check and adjustment mode are inhibited. The machine-locked condition is removed when the pre-adjustment information is erased during a clear operation.
