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.
