PURPOSE: To offer smooth counter service while reducing labor by providing a subordinate unit, equipped with an item-number display unit and purchase-amount display unit, to a master unit equipped with a purchase-item-number display unit, purchase-weight difference display unit, purchase-amount display unit, and measuring method with a stabilized pan.
CONSTITUTION: Main frame 7 of master unit A is provided with a measuring method with stabilized pan 8, purchase-item-number display unit 9, unit-price display unit 10, display unit 11 for a difference between the set weight of subordinate unit B and actual purchase weight, purchase-amount display unit 12, and display unit 13 for the number of subordinate unit B in operation. Master unit A like this is provided with wire or wireless subordinate unit B. Main frame 17 of this subordinate unit B is provided with display unit 19 showing that the main unit is under measurement, purchase-item-number display unit 20 and purchase-weight display unit 22. Using subordinate unit B together with master unit A results in that a store side only measures an item indicated by subordinate unit B, and consequently an error due to mishearing can be eliminated, offering smooth counter service.
