SOLUTION: A microcomputer comprising a CPU and a memory is connected with an weighing section comprising an weighing pan, a touch screen, a printer, and the like. When an article is ordered from a client under a state where an weighing screen is displayed on the touch screen, a specified quantity is weighed on the weighing pan and then the CPU displays the name, unit rice and price on the weighing screen depending on button operation. Subsequently, the CPU displays a list screen on the touch screen along with the name of a person in charge and the total sum of money. When purchase of a part of articles is cancelled, the CPU displays the name and price of an article to be cancelled while superposing double lines thereon and discriminating from other articles.
