Abstract

An article file control system includes a host computer for controlling a master article file (which includes article data of various department articles including data items of article codes and unit prices), and a plurality of terminal groups provided for respective article departments. Each terminal group includes a first-type electronic weighing and pricing device (EWPD) for radio communication with the host computer and a second-type EWPD for wire communication with the first-type EWPD. The host computer includes a CPU for reading out article data of each department from the master article file and transmitting the article data to the first-type EWPD of a corresponding one of the terminal groups. The first-type EWPD of each of the terminal groups includes a CPU for receiving article data transmitted from the host computer, transmitting the article data to all of the second-type EWPDs of the same terminal group and controlling a department article file comprised of the received article data. The second-type EWPD of each of the terminal groups includes a CPU for receiving article data transmitted from the first-type EWPD of the same terminal group and controlling a department article file comprised of the received article data.
