Then, the corresponding laser distance measuring instrument 30 detects the height of plates 9 on a counter, and transfers the height data to a controlling and communicating device 12, and the controlling and communicating device 12 transmits the data through the LAN 11 to the POS terminal 10. Then, the POS terminal 10 receives the height data of the plates 9 transmitted from the controlling and communicating device 12, calculates the number of the plates 9 based on the height information of each plate different for each unit price classification preliminrily stored in a memory 25 of a PC part 21, totals the number of the plates 9, calculates the accounted sum, and displays it on a display part.
