  The measurement system according to the first embodiment of the present invention can accurately measure the weight value of the article 100 and read the information of the ID tag 10 provided on the article 100. The reason for this will be described.

When the ID tag 10 and the reader / writer 20 communicate with each other by radio waves, radio waves and electromagnetic waves are generated from the antenna 11 of the ID tag 10 and the antenna 21 of the reader / writer 20, and this adversely affects the electronic balance 1 as noise. This will be described. As described above, the weight measuring unit 3 measures the load when the article 100 is placed on the tray unit 30 (distortion of the tray unit 30) as a voltage, and converts the voltage into the weight value of the article 100. In the weight measuring unit 3, the voltage measured by the strain of the tray unit 30 is weak. This weak voltage is susceptible to noise. For this reason, the weight measurement part 3 will measure an incorrect weight value, when it receives to the influence of noise.
In such a case, it is possible to shield the space between the antenna 21 and the weight measuring unit 3 with metal by changing the tray 31 and the cover 32 of the tray unit 30 from non-metal to metal. 30 affects the reading of information (tag identifier) of the ID tag 10.

  Therefore, in the measurement system according to the first embodiment of the present invention, when the article 100 is placed on the saucer 30 of the electronic balance 1, the weight measuring unit 3 transmits the weight value of the article 100 to the server 4. At this time, the server 4 receives the weight value from the weight measuring unit 3 and transmits a read request to the reader / writer 20 using the weight value (determined weight value) as a trigger. In response to the reading request, the reader / writer 20 communicates with the ID tag 10 provided on the article 100 via the antenna 21 and performs a reading operation to acquire the tag identifier 10 '. Thus, when the reading operation is not performed, radio waves and electromagnetic waves are not generated from the antenna 11 of the ID tag 10 and the antenna 21 of the reader / writer 20. In particular, when the weight measuring unit 3 measures the weight value of the article 100, the above reading operation is not performed. In the measurement system according to the first embodiment of the present invention, the reader / writer 20 reads the information (tag identifier 10 ′) of the ID tag 10 after the weight measuring unit 3 measures the weight value of the article 100. The weight measuring unit 3 can accurately measure the weight value of the article 100 without radio waves or electromagnetic waves being affected by the electronic balance 1 as noise.
