Abstract

PURPOSE:To prevent illegal use and malfunction by discriminating whether an operated function is usable or not by previously setting usable and unusable function key by persons in charge, and then comparing an input with a preset value when the function key is operated. CONSTITUTION:A memory 12 is connected to the CPU11 of an ECR through a data bus DB, an address bus AB, and a control bus CB, and in an area of this memory 12 where data on function keys by persons in charge are stored, data by persons in charge on whether the function keys are usable or not are set. When a discrimination code by persons in charge is inputted from an input part 16 connected to an input controlling part 13, the CPU11 reads the set value of the usable or unusable state of the person in charge; when the key is usable, normal registering processing is performed and when unusable, error processing is performed to display the state at a display part 17 and a printing part 18, thus preventing illegal use and malfunction.
