Description

  The present invention relates to a label to be attached to an article, and more particularly to an RFID label provided with a so-called RFID tag having a memory chip for storing various information and an RFID label attaching method.

In recent years, as shown in FIG. 7, the RFID (Radio Fruquency IDntification) tag T is called a tag having a memory chip Ta for storing various information and a communication antenna Tb connected to the memory chip Ta. A technique of attaching to a label L attached to an article and performing wireless non-contact automatic identification using the RFID tag T has been widespread.
FIG. 7 shows a label L to which an RFID tag T is attached. The label L includes a display layer U and an adhesive layer B. The RFID tag T is attached to the back surface of the display layer U, and a belt-like mount D It is temporarily attached to.
The RFID tag T includes an IC chip Ta and a communication antenna Tb, and is protected by a film layer J that covers the whole.
As such a label sticking device for sticking the label L with the RFID tag T attached to an article, for example, one previously proposed by the applicant of the present application is known (Japanese Patent Laid-Open No. 2005-104521). Published). This is because the label L is transported in a temporarily attached state on the mount D, and the label L peeled off from the mount D is sucked by a suction plate at a predetermined suction position, and the label L sucked by the suction plate is placed at a predetermined sticking position. It is affixed to an article.

  Further, for example, a label L as shown in FIG. 8 has been developed in order to make the communicable distance constant in a label provided with an RFID tag. The label L is divided into, for example, three regions 110, 111, and 112 that can be bent as a whole. The memory chip Ta and the communication antenna Tb are mounted in one region 110, and the antennas are disposed in the other regions 111 and 112. Tb is mounted, and, for example, it can be bent and pasted so that each region 110, 111, 112 faces the three surfaces constituting the corner of the article, and the communication conditions can be similarly performed in the three directions. (For example, it is published in Unexamined-Japanese-Patent No. 2003-212348).

  However, in the conventional label L, although it varies depending on the frequency, in particular, in the RFID tag T in the UHF band, the material and contents of the article to which the label L is attached inhibits electromagnetic waves, for example, liquid such as metal and water. In other words, the information on the memory chip Ta may not be read / written by the reader / writer because the electromagnetic wave is absorbed by the article due to the influence of the metal or liquid of the article or the electromagnetic wave is disturbed by irregular reflection. was there.

  In order to solve this, for example, as shown in FIG. 9, a label L is affixed to an article W via a cylindrical hollow object 100, a gap 101 is provided between the label L and the article W, and an RFID tag It is effective to separate T from the article W and suppress the influence from the article W as much as possible (see, for example, Japanese Patent Application Laid-Open No. 11-240523).
