PURPOSE:To separate a seller-side display and a buyer-side display completely by providing a display circuit which controls a seller-side display device and a buyer-side display device independently. CONSTITUTION:A load cell 16 which measures weight is connected to a CPU 18 through an analog-digital converter 17. Further, a display block 23 including a control circuit is connected to the CPU 18 and a mode display unit 8 is connected to the display block 23. Specially, a weight display device 12, a unit price display device 13, and a price display device 14 use the same circuits between the shop-side display device 9 and customer-side display device 10, but individual control circuits are connected to message display devices 11 of the seller-side display device 9 and buyer-side display device 10 so as to control their display contents independently.
