Description

  The present invention relates to an RFID tag that can be attached to a sheet-like object.

  The RFID tag is a tag in which a minute wireless IC chip used for identifying an object is incorporated. The wireless IC chip stores information such as its own identification code and has the ability to send and receive information to and from the management system using radio waves. Therefore, research has been conducted as a product identification and management technology that replaces barcodes in the industry. It is being advanced. Recently, it has been attracting attention as a fundamental technology for promoting the IT and automation of society.

  There are various types of RFID tags, such as a label type, a card type, a coin type, and a stick type, which can be selected according to the application, but the present invention is an RFID tag that can be attached to a sheet-like object. The communication distance ranges from several millimeters to several meters, and these are also properly used depending on the application.

  When the RFID tag is attached to a management object such as a product, some attachment means is required.

For example, in the following Patent Document 1, a record carrier unit is configured in a state where a record carrier such as an IC chip is sandwiched and sealed between a first resin layer and a second resin layer. And this record carrier unit is arrange | positioned with respect to the single side | surface of the base material on which various information was displayed from the 1st resin layer side. It is “sewed on” ([0020]) to an object to be managed, such as clothing. In addition, fixing with a staple is introduced as a conventional technique.
JP 2005-331917 A

  In the above prior art, a sewing thread or a staple is used, but it is often inappropriate depending on the object. For example, these attachment means cannot be used for sheet-like objects such as those used in the following embodiments, such as a document holder.

  The present invention has been made in view of this problem, and provides an RFID tag that can be easily attached to and detached from a sheet-like object such as a document holder and can be easily read and written by a reader / writer. For the purpose.

  An RFID tag that can be attached to a sheet-like object of the present invention comprises a main body forming a tag, a clip attached to the main body, and an IC chip, and the sheet-like object is sandwiched between the main body and the clip. Is possible.

  According to the present invention, a sheet-like object such as a document holder can be easily attached and detached, and reading and writing by a reader / writer is easy.

  The IC chip is preferably housed in an IC chip housing chamber provided in the main body.

  For the clip, for example, a wire formed by intersecting an ellipse and both ends thereof can be used. Other clips known per se can also be used.

  In order to attach this clip to the main body, it is preferable that the main body is made into a block that is divided into two vertically and the upper and lower blocks are integrated after the wire is assembled.

  More preferably, the upper block includes an upper surface portion, a front hanging portion that extends downward from the front center of the upper surface portion, and a rear hanging portion that extends downward from the left and right rear sides of the upper surface portion, and the lower block is an upper portion. It consists of a main body part having a dent in the center and two protrusions rising from the left and right sides of the main body part. A small dent is formed on the front hanging part on the front side, and each of the left and right rear hanging parts also has a front part. A small recess is formed on the side, and a passage that can accommodate both ends of the wire forming the clip is formed in the main body, and the main front of the main body is engaged with the recess of the front hanging part A possible stopper is formed, and both of the two protrusions are formed with stoppers that can be engaged with the recesses of the rear hanging portion.

  In order to accommodate the IC chip, it is preferable that an internal space serving as a storage chamber for the IC chip is formed in the upper surface portion. This is because when the tag is attached to the sheet-like object, the upper surface portion appears on the outside front surface, so that reading and writing by a reader / writer becomes easy.

  In addition, an IC chip can be attached to the upper surface portion with an adhesive or the like without providing a storage chamber.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIGS. 1A and 1B are perspective views showing a usage state of an RFID tag according to an embodiment of the present invention. This shows a state where an RFID tag is attached to a document holder in which a trade secret or the like is bound. (A) is attached to the back side of the thick document holder H1, and (b) is attached to the top side of the thin document holder H2. As will be described later, an IC chip is incorporated on the external surface of the RFID tag, which is convenient for reading and writing with a reader / writer from the outside.

  2A and 2B are enlarged views of the RFID tag 1, wherein FIG. 2A is a front view and FIG. 2B is a perspective view viewed from the back side. As is clear from this figure, this RFID tag is formed by combining plate-like plastic block upper and lower two parts 2 and 3 and has a clip 4 for attaching to an attachment object.

  FIG. 3 is an exploded perspective view of FIG. The upper block 2 includes an upper surface portion 21, a front hanging portion 22 extending downward from the front center of the upper surface portion 21, and rear hanging portions 23, 23 extending downward from the left and right rear sides of the upper surface portion 21.

  The upper surface portion 21 is formed with storage chambers 24, 24 in which the IC chip 5 can be stored. The storage chambers 24 and 24 are internal spaces having a passage through which the IC chip 5 can be inserted from the outside. The passage is preferably filled after the IC chip 5 is inserted.

  As shown in FIGS. 5 and 6, the front hanging part 22 is formed with a step in the middle, and a small recess 222 is formed on the front side of the narrowed tip part 221.

  As shown in FIGS. 5 and 6, the rear hanging parts 23, 23 are each formed with a small recess 231 on the front side.

  As shown in FIGS. 3, 4, and 6, the lower block 3 includes a main body 32 having a recess 31 in the upper center, and two protrusions 33 and 33 that stand up from the left and right of the main body 32.

  The main body portion 32 is formed with passages 34 and 34 that can accommodate both ends 41 of the wire forming the clip 4. In addition, a retainer 35 that can be engaged with the depression 222 in the front hanging portion is formed on the central front surface of the main body 32.

  Both of the two protrusions 33 are formed with retaining members 36 that can be engaged with the recesses 231 of the rear hanging portion 23.

  As best shown in FIG. 4, the wire forming the clip 4 includes a portion that intersects and forms an ellipse and both ends 41 and 41 thereof. Both ends are accommodated in the passage 34 of the main body and integrated with the main body 32 as described above.

  When the upper and lower blocks 2 and 3 are integrated, as shown in FIG. 6, the recess 222 in the front hanging part and the retaining part 35 of the main body part are engaged, and the recess 231 in the rear hanging part and the retaining part 36 of the main body part are engaged. Match. It is a kind of hell fit and difficult to separate.

  To attach the RFID tag 1 to the document holders H1 and H2 (FIG. 1), it is only necessary to sandwich the cover of the holder between the RFID tag main body 32 and the clip 4. In order to remove the RFID tag, the RFID tag may be picked and removed with a finger.

  The RFID tag is used only by reading the information of the IC chip accommodated on the external surface with a reader or writing with a writer, as in the past.

FIGS. 1A and 1B are perspective views showing a usage state of an RFID tag according to an embodiment of the present invention. It is an enlarged view of an RFID tag, (a) is a front view, (b) is a perspective view seen from the back side. FIG. 3 is an exploded perspective view of FIG. 2. It is (a) front view, (b) rear view, (c) side view, (d) plan view, and (f) bottom view of the lower block. It is (a) front view, (b) rear view, (c) side view, (d) plan view, and (f) bottom view of the upper block. In the cross-sectional view of the RFID tag, (a) is before coupling and (b) is after coupling.
