    摘要: In the inventory management system managing the inventory status of a commodity displayed in a showcase by using a computer, the showcase is provided with an antenna for communicating with an RFID tag attached to a commodity on a commodity shelf, detecting means for detecting a unique number of the RFID tag by communicating with the RFID tag through the antenna, and transmitting means for transmitting the detected unique number of the RFID tag to the computer through a network. The computer manages the commodity inventory based on the unique number of the RFID tag, the unique number being received from the showcase.

    摘要: A control unit of a reader superimposes a control signal for impedance adjustment on a high-frequency signal outputted from a high-frequency circuit to an antenna unit to output a superimposed signal. The antenna unit includes a separating unit that separates the superimposed signal into the high-frequency signal and the control signal, a matching circuit that subjects the high-frequency signal separated by the separating unit to impedance matching and input the high-frequency signal to an antenna, and an adjusting unit that controls a circuit constant of the matching circuit on the basis of the control signal separated by the separating unit.
