PURPOSE:To facilitate the check of a finish state by erasing a slip number and order data, and shifting them up successively by each display device, when a display of the order data is inverted. CONSTITUTION:Each display device 4 is constituted of a control part 7, a display part 8, and a keyboard 9. In such a state, a control part 17 of a POS terminal 2 transmits order data to the display device 4 side through an interface circuit 20, inputs it to the control part 7 through an interface circuit 10, and displays it on the display part 8 of the device 4. In the case one of the order data is finished, when a setting key of the keyboard 9 is depressed, the display of all the order data related to one slip is inverted. In this case, a slip number and the order data are erased from the display part 8 of the device 4 through the terminal 2, and also, the next slip number and the order data are shifted up between each device 4, and the finish state is checked easily. |
