PURPOSE: To reduce the register wail time at a cashier by reading identification codes of commodities altogether, calculating a charge corresponding to the commodity identification code and displaying instantaneously the result. CONSTITUTION: Plural articles 1 with charge display responders 2 contained in a cage A are brought into a frame of a reception section 15 of a charge computing element section 3, each responder 2 or the like receives an oscillation energy from an energy supply source 6 at its reception section 8 and a rectifier section 9 rectifies the vibration energy. Then, a carrier oscillator 11 and an commodity identification code signal generating section 12 receiving power from a power supply section 10 are operated and the article code signal from the commodity identification code signal generating section 12 is sent from a transmission section 14 with a delay by a delay time decided for every commodity is advance at a delay circuit 13. The charge computing element section 3 uses an identification section 17 to identify the commodity identification code, a charge arithmetic section 20 calculates the total sum of charges and a receipt issuing device 23 issues receipt. |
