IC TAG READER

摘要

An antenna (8) radiates radio waves for reading information stored in an IC tag (7). At the time of arranging the antenna on one side of a path section (13) where a body (10), which has the IC tag (7) and is to be identified, passes through, a radio wave absorbing front wall (2) and a radio wave absorbing rear wall (3) are arranged to protrude from the vicinity of the front end and the rear end of the antenna (8) to the path section (13) in order to narrow the half-value angle of the radio waves radiated from the antenna (8) in a plan view. Furthermore, a radio wave absorbing side wall (1) is arranged on the other side by having the path section (13) in between. Thus, the propagating area of the radio waves is controlled, and an area for reading the IC tag (7) is limited by suppressing influence of reflected waves.
