Token storage device
Provided is a chip tray which is capable of accurately reading out an IC tag for use in RFID without increasing a magnitude of a magnetic field generated by an antenna. A magnetic field generating antenna is disposed along a direction in which a plurality of tokens having embedded therein feeder antennas of IC tags for use in RFID are stacked.
1. A token storage device comprising:
a storage part for storing in a stacked manner a plurality of tokens having feeder antennas of IC tags for use in RFID embedded therein; and
a magnetic field generating antenna being disposed along a direction in which the tokens are stacked so as to develop electromotive force by exerting a magnetic field on the feeder antennas,
wherein a part of each coiling part of the magnetic field generating antenna for generating the magnetic field by coiling an electric current is disposed in parallel with a part of a coiling part of the feeder antenna so as to face the part of the coiling part of the feeder antenna.
2. The token storage device according to claim 1 , wherein a storage bottom face of the storage part for storing the plurality of tokens in the stacked manner is formed so as to be inclined.
3. The token storage device according to claim 1 , wherein
a plurality of coiling parts of the magnetic field generating antenna are disposed in the direction in which the tokens are stacked, and
a distance between neighboring coiling parts of the magnetic field generating antenna is larger than a distance between the feeder antennas embedded in the tokens, with the feeder antennas being stacked.
