Abstract
A housing accommodates an article to which an RF tag is attached. A top portion of the housing has an opening. A left side portion, a back portion, and a right side portion include radio wave absorbing layers, respectively. The upper ends of these portions are higher than the upper end of a front portion. A front housing limiting plate divides the inside of the housing into a first attenuation space near the front portion and a housing space near the back portion. The article can be accommodated only in the housing space. The article cannot be accommodated in the first attenuation space. A bottom antenna is located on the upper surface of a bottom portion. The bottom antenna radiates a radio wave with high intensity toward the housing space and radiates a radio wave with low intensity toward the first attenuation space.
Claims16
A reading apparatus reading information from a passive RF tag comprising a housing accommodating an article to which the RF tag is attached;
- the housing comprising:
- a top portion having an opening through which can take the article in and out of the housing;
- a bottom portion;
- a front portion having no antenna for communicating with the RF tag;
- a first side portion having one end fixed to one end of the front portion, and having no antenna for communicating with the RF tag;
- a back portion being opposed to the front portion, having one end fixed to the other end of the first side portion, including a radio wave absorbing layer, having no antenna for communicating with the RF tag, and having a higher upper end than an upper end of the front portion;
- a second side portion being opposed to the first side portion, having one end and the other end fixed to the other end of the back portion and the other end of the front portion, respectively, including a radio wave absorbing layer, having no antenna for communicating with the RF tag, and having a higher upper end than the upper end of the front portion;
- a first housing limiting portion dividing the inside of the housing into a first attenuation space incapable of accommodating the article between the front portion and the first housing limiting portion, and a housing space capable of accommodating the article between the first housing limiting portion and the back portion;
- and
- a bottom antenna located on the upper surface of the bottom portion at a position at which a radio wave with high intensity is radiated toward the housing space and a radio wave with lower intensity than the intensity of the radio wave radiated toward the housing space is radiated toward the first attenuation space.
