Abstract
A top part 110 includes a placement portion 111 and a prohibition portion 112. The placement portion 111 and the prohibition portion 112 are made of a material that allows radio waves to pass through. An article 300 to which an RF tag 301 is attached can be placed on the upper surface of the placement portion 111. The prohibition portion 112 surrounds the placement portion 111. An RF tag 301 is prohibited from being placed on the prohibition portion 112. The antenna for communicating with the RF tag 301 is below the placement portion 111. The antenna is located at a position where a radio wave with high intensity is radiated toward the placement portion 111 and the radio wave with lower intensity than that of the radio wave radiated toward the placement portion 111 is radiated toward the prohibition portion 112.
Claims8
A reading apparatus reading information from a passive RF tag, comprising:
- a top part, comprising:
- a placement portion made of a material that allows radio waves to pass through without a material that blocks and/or reflects them and on which an article to which the RF tag is attached may be placed;
- and
- a prohibition portion made of a material that allows radio waves to pass through without a material that blocks and/or reflects them, surrounding the placement portion and on which the article is prohibited from being placed;
- wherein there is a gap between an outer edge of the placement portion and an outer edge of the prohibition portion;
- and
- an antenna radiating a radio wave for communicating with the RF tag, being below the placement portion so that the radio wave propagates while spreading upward to reach the placement portion and the prohibition portion, and being located at a position where the radio wave with high intensity is radiated toward the placement portion and the radio wave with lower intensity than that of the radio wave radiated toward the placement portion is radiated toward the prohibition portion;
- wherein since there is the gap between the outer edge of the placement portion and the outer edge of the prohibition portion, there is a low possibility that the reading apparatus fails to read information from an RF tag placed on the upper surface of the placement portion and the reading apparatus can prevent accidentally reading information from an RF tag around the top part.
