<p>PROBLEM TO BE SOLVED: To make effectively settable a PLU(price look-up) by copying the set information corresponding to a key of a certain key input screen as the set information corresponding to the key set at the same position as the key on another key input screen when the set information is written into a data storage means in response to the key information. SOLUTION: The input device 5 is a touch panel system that contains a key input screen of three layers A to C. A PLU file 2-1 of a RAM 2 constructs a commodity-based sales totalizer. If the characters, the unit prices and other set data which are contained in the file 2-1 are changed or newly set, the relevant record stored in the file 2-1 is copied as the set information corresponding to the PLU key set at the same position as a PLU key of another key input screen when the PLU information are set to the file 2-1 in response to plural PLU keys of a key input screen that is presently designated for its switching.</p> |
