Ic tag reading device

An IC tag reading device, comprising:

• an antenna provided on one side of a passageway for an identification subject with an IC tag to pass, the antenna being adapted to radiate a radio wave for reading information stored in the IC tag;
• and
• front and rear wave-absorbing walls which are respectively provided on front and rear sides with respect to the antenna in a direction of passage of the identification subject in the passageway such that a half-power angle of the radio wave radiated from the antenna over a horizontal plane is narrowed.

An IC tag reading device, comprising:

• antennas provided on both sides of a passageway for an identification subject with an IC tag to pass, the antennas being adapted to radiate a radio wave for reading information stored in the IC tag;
• and
• front and rear wave-absorbing walls which are respectively provided on front and rear sides with respect to the corresponding antennas in a direction of passage of the identification subject in the passageway such that a half-power angle of the radio wave radiated from the corresponding antenna over a horizontal plane is narrowed.

• antennas provided on both sides of a passageway for an identification subject with an IC tag to pass, the antennas being adapted to radiate a radio wave for reading information stored in the IC tag;
• and
• wave-absorbing side walls provided on the respective sides of the passageway opposite to the corresponding antennas.
