Description

  The present invention relates to an RFID cover sheet for inserting an RFID inlay into an RFID card, and a printing mount used for printing on the RFID cover sheet.

  The RFID is also called an IC tag, an RF tag, a wireless tag, an electronic tag, or the like, and is used for the purpose of integrating an object to which this is attached and information related to the object. An inlay refers to an RFID circuit unit in which an antenna and an IC chip connected to the antenna are fixed on a base film such as PET.

In a conventional RFID card, an inlay is sandwiched between a top sheet and a back sheet, and is strongly bonded to these sheets (see, for example, Patent Document 1).
JP 2000-6560 A

Conventionally, RFID cards have been used for the same purpose for a relatively long period of time such as railway tickets and ID cards for employees in large companies, and many cards of the same type have been used. However, the use of RFID has increased, and the use of short-term use (for example, exhibition cards, attendance cards for meeting visitors) and a small number of uses (for example, use as employee ID cards in small businesses) has also increased. doing.
The RFID can rewrite data recorded on the IC chip. Therefore, if the used RFID card is collected, and the RFID inlay is taken out and reused, it does not become a burden on the environment and the cost can be saved.

In the conventional RFID card, the inlay is strongly bonded or adhered to the front and back substrates of the card, and it has been difficult to remove the inlay from the card without damaging the inlay.
In addition, in the conventional RFID card, the inlay is inserted by applying heat or pressure using a large machine, and the front and back surfaces of the RFID card are printed using a dedicated printing machine. It was inconvenient for small card production.

Therefore, an object of the present invention is to obtain an RFID cover sheet for creating an RFID card that facilitates the work of taking out an inlay from a used RFID card and hardly damages the inlay during the takeout work.
Another object of the present invention is to obtain an RFID cover sheet in which an inlay can be inserted without using a dedicated machine.

  Another object of the present invention is to obtain an RFID cover sheet that can be printed on the surface of an RFID card with a printer for daily office work or home use. Another object of the present invention is to obtain a printing mount for an RFID cover sheet that enables such printing.

  Other problems of the present invention will become apparent from the following description of the present invention.

  In order to solve the above problems, an RFID cover sheet according to one aspect of the present invention is an RFID cover sheet into which an RFID inlay (21) is inserted, and can cover the entire planar area of the inlay. A front sheet (12) having a rectangular planar shape and a resin back sheet (13) having substantially the same planar shape as the front sheet and having an opacity of 70% or less, and superposing the front sheet and the back sheet, In the vicinity of one side of the front sheet, a belt-like fixing region (14) extending along the side is formed to make the side a fixing side (41), and the front sheet is fixed to the back sheet in the fixing region. And a belt-like region extending along the side in the vicinity of two sides (42, 43) adjacent to the fixing side on either one of the two sides facing the front sheet and the back sheet And the side in the vicinity of the side (44) facing the fixed side The strip-like regions extending along and attached coating an adhesive to form an outer peripheral adhesive coated region (15), in which the entire surface of the outer peripheral adhesive application area is covered with release paper.

  In the RFID card made from the RFID cover sheet of the present invention, the entire surface of the inlay or most of the surface of the inlay does not stick to the front sheet or the back sheet, but is only sandwiched. Further, the back sheet has an opacity of 70% or less, and the inlay is seen through the back sheet. For this reason, if the vicinity of the inlay of the RFID card is cut out with scissors or the like, the inlay can be easily taken out without being damaged.

  Further, in the RFID cover sheet of the present invention, the front and back sheets have a fixed area fixed in advance, and an adhesive is applied to the outer peripheral adhesive applied area. Therefore, the RFID card is completed only by removing the release agent covering the outer peripheral adhesive application region, positioning the inlay at the center, and lightly pressing the front sheet and the back sheet.

In the present invention, opacity is opacity defined in JIS P 8148: 2000 paper and paperboard-Opacity test method (backing of paper)-Diffuse illumination method. For the same sample, single sheet luminous reflectance coefficient R the ratio of intrinsic luminous reflectance factor R _{∞ 0} is defined as a value expressed as a percentage.

  In a preferred embodiment of the RFID cover sheet according to the present invention, the front sheet is a synthetic resin sheet, and the surface of the front sheet is opposite to the surface facing the back sheet. Printing may be possible depending on the method.

  Inkjet printers are widely used for general office use. Since the front cover sheet of the RFID cover sheet according to this preferred embodiment can be printed by the ink jet method, it can be printed using a general-purpose ink jet printer, and is more suitable for multi-product small-volume production. Further, since the front sheet is made of synthetic resin, both the front sheet and the back sheet are made of synthetic resin. For this reason, when peeling off the adhered front and back sheets, the sheet is less likely to be delaminated, and an RFID card with easier inlay removal is produced.

  The ink jet printable synthetic resin sheet means a synthetic resin sheet that has been subjected to ink receiving processing so as to bring out the printing function of the ink jet method to the maximum by setting the bleeding property within a specific range.

  However, the front sheet constituting the RFID cover sheet according to the present invention is not limited to a surface having an ink jet printable surface, but has a surface that can be written by hand, and other printing methods (for example, home screen printing). It may have a possible surface. The material of the front sheet is not limited to synthetic resin, and may be paper or a biodegradable resin sheet.

In a preferred embodiment of the RFID cover sheet according to the present invention, the cover sheet is on either one of the two surfaces facing the front sheet and the back sheet, and is 100 mm ² inside the outer peripheral adhesive application region. The fine adhesive application region (17) may be formed by applying an adhesive with the following area.

  Since the RFID cover sheet according to this preferred embodiment is provided with a micro-adhesive application region, the RFID cover sheet can be temporarily fixed during the inlay insertion work, and the insertion work is easier. Can be obtained.

The area where the fine adhesive is applied only needs to serve as a temporary fixing, and if it adheres firmly, it may interfere with the removal of the inlay, so the area is 100 mm ² or less. Further, the position of the minute adhesive application region is not particularly limited as long as it is within the region surrounded by the fixing region and the outer peripheral adhesive application region, but it is preferably formed in the central portion of the region.

  However, in the RFID cover sheet according to the present invention, it is not always necessary to provide a fine adhesive application region. For example, a part of the inlay may be adhered and temporarily fixed to a part of the outer peripheral adhesive application region, and the inlay may be inserted.

  A printing mount for printing an RFID cover sheet according to one aspect of the present invention is a printing mount (6) for printing an RFID cover sheet according to the present invention, and has a size of A6 or more and A5 or less. (30) and a frame-like sheet (31) having an outline contour equal to the outline contour of the mount, and the frame-like sheet is fixed to the mount with the outline contours aligned with each other. The central space of the frame-shaped sheet is large enough to contain the RFID cover sheet according to the present invention, and a weak adhesive layer is applied by applying a weak adhesive on the mount in the central space portion ( 33), and the median adhesive strength of the weak pressure-sensitive adhesive layer 15 by the 180 degree peeling method on the SUS plate is 0.2 N / 25 mm or more and 0.4 N / 25 mm or less, and the thickness of the frame-shaped sheet (36) is the thickness of the RFID cover sheet (37 ) Is a printing mount for printing an RFID cover sheet according to the present invention.

  In general office and home printers, it is often impossible to pass small paper such as business card size. When this printing mount is used, even a small RFID cover sheet such as a business card size can be printed by a general office printer. Therefore, it is easier to produce various kinds and small quantities of RFID cards.

  The adhesive force of the weak adhesive layer is measured according to JIS-Z-0237. The said numerical value is the median value of the measured value by 180 degree | times peeling method on a SUS board.

  According to the RFID cover sheet of the present invention, it is easy to take out the inlay from the used RFID card, and it is possible to obtain an RFID card in which the inlay is hardly damaged during the taking out operation. Further, it is possible to obtain an RFID cover sheet in which an inlay can be inserted without using a dedicated machine.

  Furthermore, according to the printing mount according to the present invention, even if the cover sheet for RFID is equal to or smaller than the sheet passing lower limit size, the RFID cover sheet can be printed with a general office printer. Therefore, by using the RFID cover sheet and the printing mount according to the present invention, it is possible to make RFID cards that are more suitable for small-scale production.

  Hereinafter, the RFID cover sheet and the printing mount according to the present invention will be described in more detail with reference to the drawings. The dimensions, materials, shapes, relative positions, etc. of the members and parts described in the embodiments of the present invention are not intended to limit the scope of the present invention to those unless otherwise specified. It is merely an illustrative example.

  FIG. 1 is an explanatory diagram showing a state where an RFID card 1 for personal identification is created using an RFID cover sheet according to the present invention and a person is wearing it. Characters are drawn on the surface of the RFID card 1 using an ink jet printer.

FIG. 2 is a perspective view for explaining an RFID cover sheet.
The RFID cover sheet 11 includes a front sheet 12 and a back sheet 13. The front sheet 12 is a sheet made of polyethylene terephthalate (PET) resin having an ink receiving process for ink jet printing on one surface. The ink receiving processed surface is the surface opposite to the surface facing the back sheet 13 (the back side of the paper in FIG. 2). The front sheet 12 is white and the opacity is 95%.
The back sheet 13 is a transparent sheet made of PET resin, and the opacity is less than 3%. The material of the back sheet may be polycarbonate, polyethersulfone, or the like.

  In this embodiment, the front sheet 12 and the back sheet 13 have the same planar shape that overlaps without excess or deficiency. In the present invention, the front sheet and the back sheet do not necessarily have the same planar shape, and one of them may have a relationship of a size that protrudes and overlaps the other outline. Furthermore, there may be a relationship in which a part of the contour line protrudes and another part of the contour line enters. However, from the viewpoint of the flatness of the ink receiving surface during printing (the surface of the front sheet 12 (the back side in FIG. 2)), the front sheet 12 is the same as the back sheet 13 or the front sheet 12 is more than the back sheet 13. Is preferably a small area.

  The front sheet 12 and the back sheet 13 are laminated and are fixed to each other by a belt-like fixing region 14 extending along the fixing side 41 in the vicinity of the fixing side 41 that is one side. The fixing may be adhesive or adhesive via an adhesive or adhesive, thermocompression bonding, welding or the like. The pressure-sensitive adhesive may be the same as the pressure-sensitive adhesive applied to the peripheral pressure-sensitive adhesive application region.

  A surface of the front sheet 12 facing the back sheet (back surface) is coated with an acrylic pressure-sensitive adhesive on the entire surface except for the fixing region 14, and a release paper is stacked thereon. The release paper is punched along a straight line parallel to the three sides (42, 43, 44) and further punched into a 3 mm × 4 mm square at the center. The punching process is a process of cutting the release paper along the processing line. The release paper is paper or a release paper that is commonly used in which a synthetic resin sheet is coated with silicon resin or fluorine resin. Here, the side 42 and the side 43 are sides adjacent to the fixed side 41, and the side 44 is a side facing the fixed side 41.

  In this way, the strip-shaped outer peripheral adhesive application region 15 is provided along the three sides in the vicinity of the three sides excluding the fixing region 14 on the surface of the back sheet 12, and the first release paper 16 is the outer peripheral adhesive application region 15. It is in a state of covering the entire surface. Similarly, the minute adhesive application region 17 is provided, and the second release paper 18 covers the minute adhesive application region 17. The second release paper 18 may or may not be present. From the viewpoint of facilitating handling because the front sheet 12 and the front sheet 13 are temporarily adhered, it is preferable that there is no second release paper 18.

The adhesive and release paper may be provided on the back sheet 13 side. In this case, when the inlay is sandwiched with a part of the release paper, a transparent release paper is used.
In the above embodiment, the adhesive is applied to almost the entire surface of the front sheet 12, but the adhesive may be applied only to the peripheral adhesive application region by a printing method or the like. And only an outer periphery adhesive application area | region may be covered with a release paper.

Next, handling of the RFID cover sheet 11 will be described.
Arbitrary characters, drawings, etc. are entered on the surface of the front sheet 12 by printing or the like. Next, the second release paper 18 is removed and the RFID inlay to be inserted is positioned between the front sheet 12 and the back sheet 13 and is pressed against the fine adhesive application region 17 to temporarily fix the inlay. Next, the 1st release paper 16 is removed, the outer periphery adhesive application | coating area | region 15 is exposed, and the front sheet 12 and the back sheet 13 are adhere | attached by pressing down the back sheet 13. FIG.

  The following can be mentioned as an example of an inlay. An antenna 22 formed by screen printing on a synthetic paper 23 having a thickness of 50 μm is bonded using a conductive paste. An IC chip 23 is conductively fixed on the antenna 22 to produce a portion to be a circuit module. A protective layer is formed on the circuit module with an EVA adhesive sheet having a thickness of 300 μm and a polyester film having a thickness of 50 μm to form an inlay. Even inlays other than those described above can be sandwiched between the RFID cover sheets according to the present invention.

FIG. 3 is an explanatory view of the back side of the RFID card with the inlay inserted.
The front and back sheets of the RFID card are fixed and adhered in the fixing region 14 and the outer peripheral adhesive application region 15. 21 is an inlay, 22 is an antenna, and 23 is an IC chip.

  When the RFID card 1 becomes unnecessary, the RFID card 1 is cut at the position of the cutting line 25 with scissors or the like. The position of the cutting line 25 is not limited, and may be, for example, between the contour line of the fixing region 14 and the contour line of the inlay 21. At this time, since the back sheet 13 has an opacity of 70% or less and the inlay 21 is seen through, an accident in which the inlay 21 is accidentally cut can be efficiently prevented. Further, the inlay 21 is only attached to the front sheet in the minute adhesive application region 17, and the inlay 21 can be removed from the front sheet without applying excessive force to the inlay 21.

  Further, since there may occur a case where the adhesive between the front sheet and the back sheet must be peeled when removing the inlay, it is preferable that the material of the front sheet 12 be a synthetic resin from the viewpoint that the sheet is less likely to cause delamination. .

Next, a printing mount for printing an RFID cover sheet will be described.
FIG. 4A is a perspective explanatory view of the printing mount, and FIG. 4B is an end face explanatory view taken along line AB.

  The print mount 6 includes a mount 30 and a frame sheet 31. The mount 30 is A6 size paper (about 100 mm × about 149 mm). The A6 size is a postcard size and is often the lower limit of the size that can be passed by a general-purpose printer. The frame-like sheet 31 is A6 size paper. The central space which is the adhesion region 32 is a size obtained by adding a minute margin to the outer peripheral contour of the RFID cover sheet. However, the size of the adhesion region 32 may be larger than the RFID cover sheet as long as the RFID cover sheet is inserted. From the viewpoint of determining the position of printed characters, designs, etc., it is preferable that the adhesion region 32 has a size that allows the RFID cover sheet to enter.

The weak adhesive layer 33 is formed on the entire surface of the mount 30 by applying an acrylate weak adhesive with a coater or the like. The median value of the adhesive strength (SUS) of the weak adhesive layer 33 measured according to JIS-Z-0237 is 0.2 N / 25 mm or more and 0.4 N / 25 mm or less (180 degree peeling method). The median of the adhesive strength (SUS) of the weak adhesive layer 33 used in this example is 0.3 N / 25 mm, and the median of the ball tack is No. 6 (J. Dow method).
The frame-like sheet 31 is adhered to the mount 30 by a part of the weak adhesive layer 33. At this time, the outline of the frame-like sheet 31 and the outline of the mount 30 are laminated so as to coincide with each other.

  Next, a method of using the printing mount 6 for printing the RFID cover sheet will be described. FIG. 5 is a cross-sectional explanatory view for explaining the usage state of the printing mount 6. The back surface of the RFID cover sheet 11 is affixed to the adhering portion 32 of the printing mount 6. The affixing is affixed with a moderate adhesive force by the weak adhesive layer 33. A line segment 37 in the figure indicates the thickness of the RFID cover sheet 11, and the thickness is substantially equal to the thickness of the frame sheet 31 (indicated by a line segment 36 in FIG. 4B). For this reason, the integral thing which stuck the cover sheet 11 for RFID on the printing mount 6 has the substantially same thickness over the whole area of a printing mount.

The integrated object in which the RFID cover sheet 11 is attached to the printing mount 6 is passed through an inkjet printer or the like, and printed on the surface of the RFID cover sheet 11. After printing, the RFID cover sheet 11 is peeled from the printing mount 6. At this time, it is a weak adhesive layer, peeled off with a light force, and the adhesive is hardly transferred to the RFID cover sheet 11 side.
In this way, it is possible to print on an RFID cover sheet that is smaller than the rated minimum sheet passing size of the ink jet printer.

The RFID cover sheet according to the present invention can be used, for example, for creating a card using RFID such as an exhibition card for an exhibition or an employee ID card.
The printing mount for printing an RFID cover sheet according to the present invention can be used for printing the RFID cover sheet.

It is explanatory drawing which shows the state which produced the RFID card | curd 1 for personal identification using the RFID cover sheet | seat, and the person has adhere | attached this. It is a perspective view explaining the cover sheet for RFID. It is back surface explanatory drawing of the RFID card which inserted the inlay.
