3 . The item managing apparatus according to claim 2 , wherein
the case and the device accommodation part are formed integrally with each other.
4 . The item managing apparatus according to claim 2 , wherein
the case is incorporated into the device accommodation part.
5 . The item managing apparatus according to claim 1 , wherein
the biasing member is a weight attached to the other end of the linear member.
6 . The item managing apparatus according to claim 1 , wherein
the item is a product arranged in a store for being tried out.
7 . An item managing system comprising:
the item managing apparatus according to claim 1 ;
a wireless device wirelessly communicating with the communication device; and
a measurement device configured to acquire a result of whether communication by the wireless device with the communication device is possible over time, and, based on the result of whether the communication is possible, to measure a frequency at which the wireless device is able to communicate with the communication device.
8 . The item managing system according to claim 7 , further comprising a reference communication device arranged at a position that is not shielded by the device accommodation part when the communication device is accommodated in the device accommodation part, wherein
the wireless device communicates with the reference communication device, and
the measurement device is configured to acquire a result of whether communication by the wireless device with the reference communication device is possible over time, and, based on the result of whether the communication is possible, to measure a frequency at which the wireless device is able to communicate with the reference communication device.
9 . The item managing system according to claim 7 , wherein
the communication device is a wireless tag that collects surrounding radio waves and converts the collected radio waves into electric power, the wireless tag including a capacitor that stores the electric power.
10 . The item managing system according to claim 7 , wherein
the communication device is a UHF-band wireless tag.
11 . The item managing system according to claim 7 , wherein
the communication device is an HF-band wireless tag.
12 . The item managing system according to claim 7 , wherein
the communication device is a microwave-band wireless tag.
13 . An item managing method comprising:
providing an item attachment device including a linear member and a biasing member, the linear member including one end that is attached to an item, the biasing member biasing the linear member from the one end in a first direction;
attaching a communication device to the linear member;
configuring a device accommodation part having an electromagnetic shielding function, in such a way that the communication device is accommodated in the device accommodation part when no external force is applied to the item against biasing force of the first direction generated by the biasing member,
exiting, by the communication device, from the device accommodation part, with external force applied to the item against the biasing force of the first direction generated by the biasing member, and communicating with a wireless device; and
acquiring a result that concerns whether communication by the wireless device with the communication device is possible over time, and measuring a frequency at which the wireless device is able to communicate with the communication device, based on the result of whether the communication is possible.
14 . An item managing system comprising:
the item managing apparatus according to claim 2 ;
a wireless device wirelessly communicating with the communication device; and
a measurement device configured to acquire a result of whether communication by the wireless device with the communication device is possible over time, and, based on the result of whether the communication is possible, to measure a frequency at which the wireless device is able to communicate with the communication device.
15 . The item managing system according to claim 14 , further comprising a reference communication device arranged at a position that is not shielded by the device accommodation part when the communication device is accommodated in the device accommodation part, wherein
the wireless device communicates with the reference communication device, and
the measurement device is configured to acquire a result of whether communication by the wireless device with the reference communication device is possible over time, and, based on the result of whether the communication is possible, to measure a frequency at which the wireless device is able to communicate with the reference communication device.
