A POS system includes a center file and a file control unit, and a plurality of electronic cash registers each including a memory having a predetermined number of data areas each for storing article data, and a control circuit which, when it is detected that the article data corresponding to the input article code is stored in the memory, executes the sales data processing operation on the basis of this article data. The file control unit supplies the corresponding article data to the control circuit in accordance with the input inquiry information. When it is detected that the article data corresponding to the input article code is not stored in the memory, the control circuit supplies the input article code as the inquiry information to the file control unit and writes the article data supplied from this file control unit into the memory.
