ABSTRACT:
This invention is provided to automate an adjusting job of a restaurant and to realize automatic sorting of tableware and to improve an operating efficiency of a restaurant job. Resonance tags are mounted on bottoms of plates of the tableware in which meals are dished up. The plates are placed on a tray, and the tray is placed on a tray placing position of an adjusting apparatus. A tag reader is buried in a lower portion of the tray placing position, and transmitting antennas and a reception antenna are superposed to form the tag reader. In this case, when radio waves of a plurality of frequencies are oscillated from the transmission antennas, different echo waves are oscillated from the resonance tags of the plates. When the echo waves are received by the reception antenna, the plates are sorted by the resonance frequencies of the resonance tags set to the respective plates. In this case, since a register calculates total amount according to a preset unit price of the meal, the meal on the tray is automatically adjusted.
