Description

The present invention relates to an IC card sleeve case. In particular, the present invention relates to an IC card sleeve case capable of reliably recognizing a specific non-contact IC card when a plurality of non-contact IC cards are stacked.

With the spread of contactless IC cards such as FeliCa (registered trademark), the number of people who own multiple IC cards is increasing. As a result, when a plurality of IC cards are held in a card case, there is a problem that it is not possible to know which card is read until it is held over a reader / writer, or money is withdrawn from a card that is not the target card. In order to prevent such a situation, it was necessary to take out the card from the card case and hold it over the reader / writer every time the card was used (see, for example, Patent Documents 1 and 2).

Further, with the spread of IC cards, IC card protectors made by pouching a metal film of punching metal have been provided and spread for the purpose of preventing skimming. By sandwiching this metal film between two IC cards, the IC card above the metal film can be made invisible by the shielding effect. However, the IC card under the metal film (reader / writer side) is also obscured by the reflection by the metal film, so that it cannot be said to be an effective means for preventing buffering between a plurality of IC cards.

In order to solve such a problem, in the non-contact type IC card holder disclosed in Patent Document 1, by sandwiching a conductive metal film between magnetic layers, the shielding effect of the metal layer and the metal shielding effect of the magnetic layer are obtained. In addition, the effect of enabling reading and writing of a desired IC card and not affecting other IC cards at that time is realized.

However, in the structure of the non-contact IC card holder disclosed in Patent Document 1, the effect coefficient must be increased in order to have good reproducibility and prevent erroneous reading, and the effect coefficient is the magnetic layer. Since it is proportional to the product of the square root of the transmittance and the thickness of the magnetic layer, a magnetic material having a high transmittance must be provided thickly. Therefore, there is an inconvenience that the magnetic layer cannot be thinned and the magnetic permeability cannot be reduced. In order to eliminate the inconvenience, Patent Document 2 proposes an IC card separator and an IC card case.

The IC card separator and the IC card case disclosed in Patent Document 2 are shown in FIG. The IC card separator 110 shown in FIG. 20 is arranged between the non-contact IC cards 124 and 128 housed in the storage portions 122 and 126 of the card case 120.

Further described, the IC card separator 110 is arranged between the two contactless IC cards 124 and 128 to prevent interference between these IC cards 124 and 128. The IC card separator 110 is a conductive metal layer, a pair of dielectric layers provided on both main surfaces of the metal layer, and a pair of dielectric layers provided on the main surfaces of the pair of dielectric layers on the IC card side. It is composed of a magnetic layer. The IC card separator 110 is characterized in that the relative permittivity of the dielectric layer is 2 or more and the thickness of the dielectric layer is 10 μm or more and 100 μm or less. Since the IC card separator 110 has such a configuration, a shielding effect by the magnetic layer and the dielectric layer can be obtained, and as a result, the magnetic layer can be thinned and the magnetic permeability can be reduced, while non-contact. The effect of being able to prevent interference between type IC cards can be obtained.

Japanese Patent No. 3630006 Japanese Unexamined Patent Publication No. 2011-13883

The IC card separator 110 disclosed in Patent Document 2 may be able to prevent interference between non-contact IC cards (124, 126), but according to the study of the inventor of the present application, the IC card separator is displaced. It turned out that there are cases where interference cannot be prevented. That is, the problem of the IC card separator is to prevent interference between non-contact IC cards even though the IC card separator is inserted, rather than what kind of magnetic layer or dielectric layer structure is used. Not being able to do it is also a big problem.

In particular, when an IC card separator that claims high performance is used, there is no problem because interference between non-contact IC cards can be prevented when the IC card separator is arranged at an appropriate position. On the other hand, when the high-performance IC card separators are misaligned, there may be cases where interference between non-contact IC cards cannot be prevented. It is the most troublesome problem for users to be able to prevent or not prevent the interference between these non-contact IC cards, and it is very difficult to determine whether the IC card separator is defective or not. And, as a practical matter, the user cannot test the performance of the IC card separator.

In addition, there are various people in the user, and even if the manual clearly explains the placement position of the IC card separator, some people roughly understand the exact position, and in the first place, explain it. Some people don't read the book. Then, when a high-performance IC card separator is used and the contactless IC card is read once or failed several times, the user doubts the performance of the IC card separator and stops using it. Very likely.

The inventor of the present application has been studying whether or not a malfunction may occur if the IC card separator is displaced when the conventional IC card separator is used to prevent interference of a non-contact IC card. In particular, when a transportation contactless IC card and another contactless IC card are used with a conventional IC card separator sandwiched between them, reading malfunction may occur when the card is held over the ticket gate. be. In this case, there is a problem that the user may be frustrated without knowing whether the IC card separator is a defective product or whether it is affected by other factors.

Nowadays, contactless IC cards are becoming widespread as credit cards, and the damage caused by criminal scanning (reading of credit card information by a scanner) is increasing. In addition, the name, expiration date, and card number are written on the front side of the credit card, and the security code is written on the back side of the credit card. If it is remembered (or mechanically scanned), the credit card is in a situation where it can be used by someone other than the person himself, so it is extremely dangerous to hand it over, and the credit card. Unauthorized use of cards can lead to criminal involvement.

Under such circumstances, the inventor of the present application is daily studying whether there is a method that can enhance the security of credit cards while preventing the interference of contactless IC cards, and that can be done easily and inexpensively. As a result, the present invention was reached.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

In addition, the dimensional relationships (length, width, thickness, etc.) in each drawing may not always accurately reflect the actual dimensional relationships. However, as shown in FIGS. 1 to 4, some of the drawings have the same dimensional relationship. In that case, a six-view drawing (thickness omitted) should be derived from the dimensional / positional relationship of each figure. Is possible.

In addition, matters other than those specifically mentioned in the present specification and necessary for carrying out the present invention can be grasped as design matters of those skilled in the art based on the prior art in the art. The present invention can be carried out based on the contents disclosed in the present specification and the drawings and the common general technical knowledge in the art. In addition, the invention is not limited to the following embodiments.

FIG. 1 shows the front configuration of the IC card sleeve case 100 according to the embodiment of the present invention. FIG. 2 shows the back configuration of the IC card sleeve case 100 of the present embodiment. Further, FIG. 3 shows the configuration of the electromagnetic wave interference prevention sheet 18 included in the IC card sleeve case 100.

The IC card sleeve case 100 of the present embodiment is composed of a storage portion (or a sleeve portion and a bag portion) 10 for accommodating an IC card. The IC card of the present embodiment is a contactless IC card, for example, a transportation IC card (Suica, PASMO, ICOCA, etc.) or a credit card (for example, American Express (registered trademark)). The non-contact type IC card is, for example, a FeliCa card (trade name), and the non-contact type IC card is equipped with an IC chip (for example, a FeliCa chip (trade name)). The contactless IC card may be a postpaid credit card, an immediate payment debit card, or a prepaid prepaid card (or a rechargeable one), and these (postpaid, immediate, prepaid) are used for convenience. , All may be called credit cards. When a non-contact IC card is held over an IC card reader device, a carrier can be transmitted to supply electric power to the non-contact IC card by electromagnetic induction, and communication can be performed between the two by modulation of the carrier. In addition, some contactless IC cards are equipped with both transportation IC cards and credit cards, and those that settle electronic money (including points or virtual currency) (T points, Rakuten points, etc.). , Rakuten Edy, etc.) The contactless IC card is not limited to a credit card, but may be a debit card or a bank (cash card). The contactless IC card to be stored in the IC card sleeve case 100 of the present embodiment is, in particular, a credit card or a transportation IC card.

The contactless IC card may not be a FeliCa card (trade name), but may be of another type. Specifically, the non-contact type IC card is, for example, a Type A / B type IC card (Type A / B IC card). The FeliCa card (trade name) has a method that is popular in Japan, and the Type A / B IC card has a method that is popular all over the world (corresponding to the NFC Type A / B standard). Is. Due to the increase in inbound demand in recent years, reading terminals (card readers) compatible with Type A / B IC cards are becoming widespread in Japan as well. In Japan as well, Sumitomo Mitsui Card, AEON Card, JAL Card, d Card, Life Card, Jacks Card, etc. have issued cards equipped with Visa's touch payment as those compatible with the Type A / B method. , Mastercard, JCB, and American Express also issue cards compatible with the Type A / B method. The main stores that support Type A / B touch payments are McDonald's, Lawson, Dotall Coffee, HUB (English-style pub), Zensho Group (Sukiya, Hamazushi, etc.), Japan Taxi, Bunkyodo (bookstore). ), TSUTAYA, glasses store, etc. There is a big difference in communication speed between the FeliCa method and the Type A / B method, and the Type A / B method has the advantage of having a communication speed of 424 kbps, while the FeliCa method has a maximum communication speed of 847 kbps, which is more than double the speed. be. This meets the needs of Japanese transportation, which requires quick payment, which is one of the reasons why FeliCa has become widespread in Japan. On the other hand, Type A / B costs more to install a reading terminal than FeliCa. It has the advantage of being inexpensive. Although the communication speed is not as high as that of FeliCa, payment at stores does not require a communication speed sufficient to withstand the rush hour of commuting in Japan, and this situation has led to the international spread of Type A / B.

A notch 15 is formed in the storage portion 10 of the present embodiment. The non-contact type IC card can be stored in the storage portion 10, and the non-contact type IC card can be easily taken out by a finger due to the portion exposed by the cutout portion 15. Further, the storage portion 10 of the present embodiment is composed of a first main surface portion 10a located on the front surface side and a second main surface portion 10b located on the back surface side with respect to the front surface side. The space (gap) between the first main surface portion 10a and the second main surface portion 10b is the card insertion gap (card storage area) 15.

The first main surface portion 10a and the second main surface portion 10b constituting the storage portion 10 have a rectangular shape corresponding to the dimensions of the non-contact type IC card. In the configuration of the present embodiment, the dimension W of the long side of the storage portion 10 (that is, the first main surface portion 10a and the second main surface portion 10b) is set to 87 mm in accordance with the dimension of the IC card. The length of the short side L is set to 55 mm according to the dimensions of the IC card. The dimensions of the IC card (credit card, cash card, Suica, etc.) are 85.6 mm on the long side (W), 54.0 mm on the short side (L), and 0.76 mm in thickness according to the ISO / JIS standard. .. The dimensions of the storage unit 10 of the present embodiment are determined according to the dimensions of the IC card. Specifically, the IC card smoothly enters the storage unit 10 and does not shift in the storage unit 10. The dimensions are large. In other words, the rectangular dimensions of the first main surface portion 10a and the second main surface portion 10b are the same as the dimensions of the IC card. Strictly speaking, the thickness of the first main surface portion 10a and the second main surface portion 10b (for example, the thickness of the sleeve material is about 0.1 mm) is only slightly larger, but this implementation includes it. In the configuration of the form, it is referred to as the same as the size of the IC card. It should be noted that the first main surface portion 10a and the second main surface portion 10b (storage portion 10) are one size larger than the size of the IC card, or a region (for example, a stitched part, a fused portion) that is one size larger than the size of the IC card. It is preferable that there is no such thing as a part, so-called "gusset"). That is, it is preferable that the rectangular shape dimensions of the first main surface portion 10a and the second main surface portion 10b are the same as the dimensions of the IC card.

The "rectangular shape" in the present embodiment is not limited to a geometrical rectangle, and may be a shape having rounded corners, and may be substantially a rectangle. In particular, since the corners of the IC card are rounded, it may be adapted to such a shape. Further, if the internal area of the storage unit 10 for storing the IC card has a rectangular shape so that the IC card does not shift in the storage unit 10, the outside of the storage unit 10 (first main surface portion 10a and second main surface portion 10b). The edges of may not be straight.

One side 12 of the long side (12, 13) of the rectangular shape that defines the shape of the storage portion 10 of the present embodiment is an insertion opening into which an IC card is inserted. A notch 15 is formed on the long side 12 which is the insertion opening. In the configuration of the present embodiment, the notch portion 15 is formed in the first main surface portion 10a, and the notch portion 15 is not formed in the second main surface portion 10b. Further, the long side 12 of the rectangular shape is an insertion opening and is not closed, but the long side 13 and both short sides 14 of the rectangular shape are closed. Therefore, the IC card can be inserted from the insertion opening (long side 12) of the storage portion 10, and the rectangular long side 13 and both short sides 14 are closed, so that the IC card cannot come out of the storage portion 10. do not have. Further, the IC card stored in the storage portion 10 can be taken out from the insertion opening (long side 12) of the storage portion 10 by grasping the portion exposed in the notch portion 15 with a finger.

The notch 15 in the illustrated example is defined by a notch line 11. The cut line 11 is formed of an inclined line portion 11a extending diagonally with respect to the long side 12 of the rectangular shape and a parallel line portion 11b extending parallel to the long side 12. Further, the notch portion 15 is located at the center of the long side 12 of the rectangular shape. The notch portion 15 of the present embodiment exposes a part of the IC card stored in the storage portion 10. The cutout portion 15 is formed at a position where information such as the card number and name of the IC card is not displayed. The notch shape of the notch portion 15 of the present embodiment is a trapezoidal shape (or a substantially trapezoidal shape). This is due to the fact that the card is identified and the shape is such that the card can be easily picked up by a finger. The notch shape of the notch portion 15 may be another shape, for example, a curved shape (an arc shape, a curved line of a part of an ellipse, or the like). Further, the notch portion 15 is preferably provided at the center of the long side 12 so that the card can be easily picked up (so that it can be easily grasped), but it may be shifted to a place other than the center.

The IC card sleeve case 100 (storage unit 10) of the present embodiment includes an electromagnetic wave interference prevention sheet 18 as shown in FIG. In the configuration of the present embodiment, the electromagnetic interference prevention sheet 18 is included in the second main surface portion 10b located on the back surface side. The size of the electromagnetic wave interference prevention sheet 18 of the present embodiment is one size smaller than the size of the second main surface portion 10b (for example, 1 mm (or less) smaller). Specifically, the long side (Wa) of the electromagnetic wave interference prevention sheet 18 is 86 mm, and the short side (L) is 54.0 mm. Further, the electromagnetic wave interference prevention sheet 18 is a sheet material made of a magnetically shielded shield material (particularly, a magnetically shielded shield material corresponding to a corresponding frequency of 13.56 MHz), and includes a soft magnetic material. For example, as the magnetically shielded shield material, a soft magnetic material containing nickel, copper, ferrite as a main component, or the like can be used, and a sheet-like material obtained by combining it with a resin can be used. However, a magnetic shield material having another component (for example, one containing iron as a main component) may be used, and the electromagnetic interference prevention sheet 18 is appropriately suitable as long as it can exhibit the shielding characteristics. Can be adopted. A sheet containing iron as a main component is sometimes referred to as a magnetic shield sheet, which is also included as an example of the electromagnetic interference prevention sheet 18 of the present embodiment. The magnetic shield sheet as the electromagnetic wave interference prevention sheet 18 of the present embodiment uses iron as a main material and has a function of absorbing magnetic force with the iron. The (external) magnetic force weakens by the amount absorbed and held inside the material. In addition, the magnetic force absorption by the magnetic shield sheet makes it possible to demagnetize to the extent that the magnetic stripe function of a credit card or the like is protected.

The storage portion 10 of the present embodiment is made of synthetic paper containing a resin material, and specifically, polyester-based synthetic paper is used as a material. Polyester-based synthetic paper (for example, Crisper (trade name)) has excellent heat resistance, water resistance, chemical resistance, and weather resistance, in addition to the property of passing electromagnetic waves smoothly, and has excellent properties of being resistant to tearing. Have. Further, by applying a matte laminating process to synthetic paper (polyester synthetic paper), it is possible to prevent the printing from peeling off, and in addition, it is possible to write with a ballpoint pen. Further, as the synthetic paper, in addition to polyester-based synthetic paper, YUPO paper (film-based synthetic paper using polypropylene as a main raw material) can be used. Further, the material constituting the storage portion 10 is not limited to synthetic paper, and any suitable material (artificial synthetic material, natural material, etc.) may be used as long as it is a material that smoothly transmits electromagnetic waves. ..

In the configuration of the present embodiment, since the storage unit 10 is made of a material (for example, synthetic paper) that smoothly transmits electromagnetic waves, the first main surface portion 10a receives the electromagnetic waves of the IC card stored in the storage unit 10. It has a function (pass) to make it transparent. On the other hand, since the electromagnetic interference prevention sheet 18 is provided on the second main surface portion 10b, the second main surface portion 10b has a function (guard) of blocking the electromagnetic waves of the IC card stored in the storage portion 10. There is. It is also possible to use the first main surface portion 10a as an electromagnetic wave blocking surface (guard surface) and the second main surface portion 10b as an electromagnetic wave transmitting surface (path surface).

Further, in the configuration of the present embodiment, since it is easy to print on the storage unit 10, print information 20.25 (character information, graphic information) is printed on at least one of the first main surface portion 10a and the second main surface portion 10b. ) Is described. In the illustrated example, the information 20 is printed on the first main surface portion (front surface) 10a. Specifically, the character 21 of the emergency contact number at the time of dropping (or when receiving relief), the telephone number 22 of the contact, and the ID number 23 are described. Further, as the graphic information (character, logo, advertising information) 24, the character (brand) 24a and the advertising information (advertiser, presiding or sponsor / sponsoring company, etc.) 24b are printed. Further, the information 25 is printed on the second main surface portion (back surface) 10b, and specifically, there is a column for personal entry items of the user. Here, there are columns for illnesses 25a that have occurred in the past, illnesses 25b that are being treated, and medicine / food / drug allergies 25c. In the configuration of the present embodiment, the surface of the storage portion 10 is subjected to a process (mat laminating process) that allows writing with a ballpoint pen, so that the user (or the substitute author) writes the columns 25a to 25c in case of emergency. It can be prepared in advance so that it can receive appropriate processing. In addition, the signature line 26 and the explanatory text 27 are also printed.

The print examples shown in FIGS. 1 and 2 have a lot of information about emergency communication, but this is a transportation IC card (Suica, etc.) in case of emergency (illness, seizure, fainting, etc.) to the user. ) And it is likely that you have a valuable credit card. That is, when something happens to the user, the person around the user can see the information (printed information 20, 24 or) described in the IC card sleeve case 100 containing the IC card (contactless IC card). If you look at the information (filled in), you can immediately contact the emergency contact and take appropriate action based on the user's medical history. In addition, instead of mainly describing such emergency contact information, advertising information and the like may be mainly described, and instead of mainly printing information, information written with a ballpoint pen or the like is mainly described. It may be the one made in. In addition, it may be left blank without any printing or description.

In the IC card sleeve case 100 of the present embodiment, the first main surface portion 10a shown in FIG. 1 and the second main surface portion 10b (including the electromagnetic wave interference prevention sheet 18) shown in FIG. 2 are bonded (that is,). It can be manufactured by bringing the sides 13 and 14 into close contact with each other). The electromagnetic wave interference prevention sheet 18 is arranged inside the second main surface portion 10b by sandwiching the electromagnetic wave interference prevention sheet 18 between two sheets to prepare the second main surface portion 10b, or a bag-shaped second main surface portion. There are a method of inserting the electromagnetic wave interference prevention sheet 18 into the surface portion 10b to seal the surface, a method of using the second main surface portion 10b having the function of the electromagnetic wave interference prevention sheet 18, and the like. Further, apart from such a method, there is also a method of folding the developed view as shown in FIG. 4 to manufacture the IC card sleeve case 100.

FIG. 4 shows a developed view of the storage unit 10. The storage unit 10 of the present embodiment is composed of a single unfolding paper member. The second main surface portion 10b is continuously connected to the sheet sandwiching portion 19 that sandwiches and stores the electromagnetic wave interference prevention sheet 18. The width W1 (84 mm) of the sheet sandwiching portion 19 is slightly shorter than the width W (87 mm) shown in FIG. 1 so as to be easy to fold (easy to assemble). That is, the sheet sandwiching portion 19 has a tapered shape from the width W to the width W1.

Further, a triangular insertion flap portion 16 is continuously connected to the first main surface portion 10a. The insertion flap portion 16 has a function of preventing the adhesive portion from peeling off when the IC card is inserted. A pair of left and right insertion flap portions 16 are provided on both sides of the long side 12. The insertion flap portion 16 has a triangular angle θ of, for example, 30 ° to 45 ° (37 ° in the illustrated example), and the tip on the triangle is rounded. The length L3 of the insertion flap portion 16 is, for example, 32 mm (± 5 mm). Further, the width W2 that defines the dimension (width) of the notch portion 15 is, for example, 30 mm (± 5 mm). In addition, the sticking portion (glue) 17 on the side surface (end side) side extends from the short side (14) of the second main surface portion 10b to both sides, and the width L1 is 45 mm (width L2 is 55 mm). That is, the sticking portion (glue) 17 is formed in a tapered shape so as to be easily folded.

When the developed view shown in FIG. 4 is assembled, the electromagnetic wave interference prevention sheet 18 is sandwiched between the second main surface portion 10b and the sheet sandwiching portion 19 and fixed, and the bonding is performed at predetermined locations (16, 17), the present embodiment is performed. An IC card sleeve case 100 can be obtained. According to this method, the storage portion (sleeve portion) 10 and the IC card sleeve case 100 can be manufactured from one unfolding paper member, which is convenient. Further, if a large number of developed drawings shown in FIG. 4 are prepared by cutting out (punching) or the like, there is an advantage that a required number of IC card sleeve cases 100 can be manufactured each time. The developed view is not limited to the one shown in FIG. 4, and may be a modified one.

In FIG. 5, a specific non-contact type IC card 90A (90) is inserted into the IC card sleeve case 100 of the present embodiment, and another non-contact type IC card 90B (90) is inserted into the back side of the IC card sleeve case 100. It shows how it was placed in. In that state, when the IC card reader device (reader / writer) is brought close to the IC card reader / writer, the non-contact IC card 90A located on the front surface side (first main surface portion 10a side) is communicated, and procedures such as payment processing are completed. do. On the other hand, the non-contact type IC card 90B arranged close to (or overlapped with) the back surface side (second main surface portion 10b side) is shielded by the electromagnetic wave interference prevention sheet 18 and does not cause interference. In particular, in the configuration of the present embodiment, simply by inserting the IC card sleeve case 100, the specific non-contact type IC card 90A is surely selected and processed without causing the positional deviation of the electromagnetic wave interference prevention sheet 18. be able to. If the antenna part (the coil-shaped antenna part built in the card) of another IC card (adjacent IC card) is exposed by about 1/3 or more, there is a risk of interference. According to the configuration of the present embodiment, such an arrangement can be prevented.

In a state where the non-contact type IC card 90A is put in the IC card sleeve case 100 of the present embodiment, it may be further put in a card case, a regular case, a wallet or the like. Since the storage unit 10 of the present embodiment is a thin sleeve member made of a material having excellent durability, it can be easily put in a card case, a regular case, a wallet, or the like.

In the IC card sleeve case 100 of the present embodiment, the storage portion 10 for accommodating the non-contact type IC card 90 has a rectangular shape corresponding to the dimensions of the non-contact type IC card 90, and the first main surface portion 10a and the second main surface portion. It is composed of 10b. Since the second main surface portion 10b includes the electromagnetic wave interference prevention sheet 18, if a specific non-contact type IC card 90A (90) is inserted in the storage portion 10, the electromagnetic wave interference prevention sheet 18 is displaced. It is possible to suppress the interference of the adjacent non-contact IC card 90B (90) without doing so. As a result, it is possible to reliably and safely read the specific non-contact IC card 90A.

Further, since the notch portion 15 is formed in the first main surface portion 10a constituting the storage portion 10, it becomes easy for the user to insert and remove the non-contact type IC card 90A with his / her finger. Further, it is possible to prevent the card information of the non-contact IC card from being seen in the area other than the notch portion in the first main surface portion 10a, which is also advantageous in terms of security. Specifically, when the non-contact IC card 90 is a regular (transportation card), personal information such as name, age, boarding / alighting station, etc. is hidden by the IC card sleeve case 100 (storage unit 10) of the present embodiment. Can be done.

When the contactless IC card 90 is a credit card, the name, expiration date, credit card number, and security code can be hidden by the IC card sleeve case 100 of the present embodiment. Therefore, when the IC card sleeve case 100 of the present embodiment is used, when the credit card (90) is used in the store, the bare credit card (90) (without the IC card sleeve case 100) is used as the clerk. It is safer to make a non-contact payment using the credit card 90 in the IC card sleeve case 100 than to deposit it. In other words, if you leave your bare credit card (90) to a clerk, there is a risk that your credit card information (name, card number, expiration date, security code) will be recognized and misused. On the other hand, if the front surface side (first main surface portion 10a side) of the IC card sleeve case 100 is held over the card reader while the credit card 90 is inserted in the IC card sleeve case 100 of the present embodiment, the payment is completed. So it's safe. Even if the store hands the credit card to the clerk, it is written on the credit card to an unspecified number of people by instructing them to put it in the IC card sleeve case 100 until just before the payment. You can ask them not to show important matters (card information). Further, even when the payment is made by the credit card of the contactless IC card 90, there is a possibility that there is a person who steals the card information not only visually but also by taking a picture of the camera, even if the payment is instantaneous. Then, since the payment can be made with the credit card 90 inserted in the IC card sleeve case 100, the card information can be sufficiently protected by the IC card sleeve case 100.

In addition, in the IC card sleeve case 100 of the present embodiment, the non-contact type IC card 90 can be electromagnetically protected by the electromagnetic interference prevention sheet, and the non-contact type IC card 90 is protected from criminal scanning. There is an effect that can be done. That is, as long as the back surface side (second main surface portion 10b) of the IC card sleeve case 100 of the present embodiment is directed outward, the card information of the non-contact type IC card 90 in the IC card sleeve case 100 is maliciously used. You can protect yourself from certain scanning. Further, the IC card sleeve case 100 (storage unit 10) of the present embodiment can physically protect the non-contact type IC card 90. That is, damage to the non-contact IC card 90 can be protected by the IC card sleeve case 100. In order to prevent damage to the non-contact IC card 90 and to protect the card information (credit card information, etc.) of the non-contact IC card 90, the area of the notch portion 15 is, for example, the first main surface portion 10a. It can be suppressed to 30% or less (or 15% or less, or 10% or less). Further, if the non-contact IC card 90 and the credit card or the like are adjacent to each other, the magnetic stripe function of the credit card or the like may be inadequate. However, by using the IC card sleeve case 100 of the present embodiment, the IC card sleeve case 100 of the present embodiment may be used. , Such a problem can be solved.

Further, in the configuration of the present embodiment, the information shown in FIGS. 1 and 2 can be written (printed, written with a ballpoint pen) on the IC card sleeve case 100. As a result, it is possible to start a business such as advertisement 24 (24a, 24b), smoothly execute emergency contact (21, 22, 23), and further, personal condition (illness, etc.). : Items to be entered in column 25) can be communicated to the discoverer / hospital. If, for example, a transportation contactless IC card (such as Suica) is used to do the same thing (as a representative of the cards that are usually worn), the transportation contactless IC card is used. There is no choice but to paste the necessary items with a sticker. Transportation contactless IC cards are often taken in and out and touched at the ticket gates, so after a month or a few months, the stickers with the necessary information will be dirty or peeled off. If you do so, you will not be able to use it in case of emergency. On the other hand, in the case of the IC card sleeve case 100 of the present embodiment, it is reassuring because the problem such as the case of sealing can be avoided and it functions properly even in the unlikely event.

FIG. 6 shows a modified example of the IC card sleeve case 100 of the present embodiment. The IC card sleeve case 100 shown in FIG. 6 has a configuration in which information (character information, graphic information, etc.) is described in the area 29 exposed by the notch portion 15 in the storage portion 10. Since this area 29 is a place displayed when the non-contact IC card 90 is pulled out, it is possible to give an impact and call attention to the person. For example, in this area 29, if a word such as "please see the back side" (or a mark for calling attention) is described, the possibility that the individual's medical history on the back side will be referred to increases.

FIG. 7 shows another modified example of the IC card sleeve case 100 of the present embodiment. In the configuration example shown in FIG. 7, the cut line 11 of the notch portion 15 is a curved line (arc or curved line) 11c. Such a notch portion 15 may be used. Further, in the IC card sleeve case 100 shown in FIG. 7, printing (20, 25, etc.) as shown in FIGS. 1 and 2 is not performed, but such a configuration (plain or no printing) is performed. ) May be.

In the above-described embodiment, the structure in which the notch portion 15 is formed on the long side 12 side of the rectangular shape of the storage portion 10 is shown, but the present invention is not limited to this. It is also possible to form the notch portion 15 on the rectangular short side 14 side of the storage portion 10. Further, FIG. 8 shows a developed view of the IC card sleeve case 100 having a structure in which the notch portion 15 is formed on the short side 14 side. Since this developed view is the same as the developed view shown in FIG. 4, duplicated description will be omitted. In the case shown in FIG. 4, the notch portion 15 is formed on the long side 12 side of the rectangular shape, whereas in the case shown in FIG. 8, the notch portion 15 is formed on the short side 12 side. There is. Here, the width w1 of the sheet sandwiching portion 19 is substantially the same as (or slightly narrower) the width L (55 mm) shown in FIG. 1, and the width w2 that defines the dimension (width) of the cutout portion 15 is For example, it is 20 mm (± 5 mm).

FIG. 9 shows the back side of the developed view (one developed paper member) of the storage portion 10 shown in FIG. The second main surface portion 10b is continuously connected to the sheet sandwiching portion 19 that sandwiches and stores the electromagnetic wave interference prevention sheet 18. In FIG. 9, the electromagnetic wave interference prevention sheet 18 is arranged on the sheet sandwiching portion 19, and the sheet is folded as shown by the arrow 55. The electromagnetic wave interference prevention sheet 18 in the present embodiment is composed of a multilayer film in which a magnetic material layer 18a and a conductive layer 18b are laminated. The conductive layer 18b is configured to be located on the back surface side of the magnetic material layer 18b. In the example shown in FIG. 9, the magnetic material layer 18a is located on the sheet sandwiching portion 19, and the conductive layer 18b is located so as to cover the magnetic material layer 18a. In this way, when folded as shown by the arrow 55, the conductive layer 18b is on the back surface side, and the magnetic material layer 18a is on the front surface side (or the side on which the IC card 90 is inserted) rather than the conductive layer 18b. Located in. Further, in the example shown in FIG. 9, the conductive layer 18b is formed on the entire surface of the electromagnetic wave interference prevention sheet 18, but when the magnetic material layer 18a is adhered and fixed, the peripheral portion of the electromagnetic wave interference prevention sheet 18 is formed. There is a glue margin (margin) 18c, and in the region of the glue margin (margin) 18c, the conductive layer 18b is adhesively fixed to the sheet sandwiching portion 19. This glue margin region should be small, and in the configuration example of the present embodiment, it is preferably, for example, 3 mm or less (for example, 2.5 mm, 2 mm, 1 mm, 0.5 mm, etc.), and the glue margin (margin). 18c is also preferably none (0 mm) or substantially none (eg, 0.2 mm or less).

FIG. 10 corresponds to the plan view shown in FIG. 3, but shows the configuration of the electromagnetic interference prevention sheet 18 shown in FIG. FIG. 11 schematically shows a cross-sectional configuration of an IC card sleeve case 100 (storage unit 10) including the electromagnetic interference prevention sheet 18 shown in FIG. For the sake of clarity, the thickness and dimensions of each layer in FIG. 11 are not accurate, and in addition, the portion of the sticking portion (glue) 17 on the side surface side shown in FIG. 9 is omitted. .. FIG. 12 shows a state in which a part of the conductive layer 18b shown in FIG. 10 is peeled off to expose a part of the magnetic material layer 18a.

As shown in FIG. 11, the IC card sleeve case 100 of the present embodiment has a second main surface portion 10b (back surface portion), a conductive layer 18b, a magnetic material layer 18a, a sheet sandwiching portion 19, and a first main surface portion from the back surface 82 side. The surface portion 10a (surface portion) is located. Here, the upper surface of the first main surface portion 10a (surface portion) is the surface 81 side. A card insertion gap (card storage area) 50 into which the IC card 90 is inserted is located between the sheet sandwiching portion 19 and the first main surface portion 10a (surface portion).

In the configuration example shown in FIG. 11, the thickness of the IC card sleeve case 100 is about 0.55 mm at the central portion and about 0.8 mm at the thickest portion. In the configuration of the present embodiment, the thickness of the IC card sleeve case 100 is preferably 1 mm or less at the thickest portion. That is, the thickness of the IC card sleeve case 100 of this embodiment is very thin. The thickness of the electromagnetic wave interference prevention sheet 18 (the total thickness of the conductive layer 18b and the magnetic material layer 18a) is about 0.2 mm. In the configuration of the present embodiment, the thickness of the electromagnetic interference prevention sheet 18 is preferably 0.3 mm or less (or 0.2 mm or less). The thickness of the sleeve material (that is, the second main surface portion 10b (back surface portion), the sheet sandwiching portion 19, and the first main surface portion 10a (front surface portion) is about 0.1 mm. The thickness of each of these layers is an example. However, it seems that the thinness of the configuration of the present embodiment can be easily understood. The thickness of the electromagnetic wave interference prevention sheet 18 shown in FIG. 3 is thin (for example, 0.5 mm or less, or 0). (3 mm or less, 0.2 mm or less). As an example of the thickness of the electromagnetic wave interference prevention sheet 18 shown in FIG. 3, 0.7 mm to 1 mm may be used, but the one shown in FIG. But thinner ones are preferable.

The conductive layer 18b of the present embodiment is a layer having conductivity (for example, a metal layer), but in this example, aluminum foil is used. Specifically, the conductive layer 18b is an aluminum foil made of aluminum or an aluminum alloy. In the illustrated example, among the conductive layers 18b, those having an adhesive function on the surface (interface 85 side) on the magnetic material layer 18a side (adhesive layer or adhesive layer) are used. In this configuration, the magnetic material layer 18a can be adhesively fixed by the adhesive surface 85 of the conductive layer 18b, and a part of the conductive layer 18b (peripheral fixing portion 18d) is made of a sleeve material at the portion of the glue margin (margin) 18c. It can be fixed to (sheet sandwiching portion 19). In this way, the conductive layer 18b (aluminum foil) can be positioned on the sleeve material (sheet sandwiching portion 19) while covering the magnetic material layer 18a. The magnetic material layer 18a is a material having a high magnetic permeability (for example, a soft magnetic material such as ferrite). In this example, the particles of the magnetic material are in the form of a sheet, but other forms may be used. In the example shown in FIG. 11, the electromagnetic interference prevention sheet 18 having one conductive layer 18b and one magnetic material layer 18a is used from the viewpoint of reducing the thickness and reducing the cost.

FIG. 13 corresponds to the plan view shown in FIG. 10, but in the configuration of the electromagnetic interference prevention sheet 18 shown in FIG. 10, there is no glue margin (margin) 18c (0 mm) or substantially no glue margin (margin) 18c (for example, 0. 2 mm or less) is shown. FIG. 14 schematically shows a cross-sectional configuration of an IC card sleeve case 100 (storage unit 10) including the electromagnetic interference prevention sheet 18 shown in FIG. In this example, the end portion of the magnetic material layer 18a reaches the end portion of the electromagnetic wave interference prevention sheet 18. Here, "the end of the magnetic material layer 18a reaches the end of the electromagnetic interference prevention sheet 18" means that the surface (side surface) of the magnetic material layer 18a does not necessarily have to be exposed, and is substantially the same. It means that there is no glue margin (margin) 18c. For example, an adhesive or a resin material may be present so that the magnetic material does not rub off from the end of the magnetic material layer 18a. Even if the surface (side surface) of the magnetic material layer 18a reaches the end of the electromagnetic wave interference prevention sheet 18 and the surface (side surface) of the magnetic material layer 18a is exposed, the sleeve material (for example, sleeve materials 10a and 17) is outside the electromagnetic wave interference prevention sheet 18. Etc.) are located, that is, because they are covered with the sleeve material, it is prevented that the magnetic material of the magnetic material layer 18a is rubbed off.

Further, the electromagnetic wave interference prevention sheet 18 (and the magnetic material layer 18a) shown in FIG. 13 has the same size (substantially the same size) as the size of the IC card 90, and the magnetic material layer is on the peripheral edge thereof. There is also no sealing portion (glue allowance 18c, 18d) for overlapping and fastening 18a. And, by compounding the adhesive material (adhesive) to the magnetic material constituting the magnetic material layer 18a, there is an advantage that it is not necessary to seal each sheet one by one. That is, when the electromagnetic wave interference prevention sheet 18 shown in FIG. 10 is manufactured, a step (seal) of attaching the adhesive surface (85) of the conductive layer 18b (aluminum foil) so as to cover the magnetic material layer 18a is attached to the sleeve material (19). Processing process) may be required, but that process can be avoided. Further, since the magnetic material layer 18a can be formed by molding in a wide area and cutting by post-processing, the processing efficiency of the sheet can be improved. And, as will be described in detail later, this structure enables more efficient passage of magnetic flux from the end face, so that more stable communication (communication) becomes possible. Further supplementarily, the dimensions of the IC card sleeve case 100 are the same as the dimensions of the IC card 70, and the dimensions of the magnetic material layer 18a are the same as the dimensions of the electromagnetic wave interference prevention sheet 18 (and the dimensions of the conductive layer 18b). Since they are the same and the dimensions of the IC card 70 are substantially the same, the magnetic flux can be efficiently passed from the end face of the electromagnetic wave interference prevention sheet 18 (magnetic material layer 18a), and as a result, it is more stable. Communication is possible.

Next, an experimental example using the IC card sleeve case 100 of the present embodiment and reading (communication state) of the non-contact IC card 90 will be described. FIG. 15 schematically shows the electromagnetic wave interference prevention sheet 18 (18a, 18a) of the present embodiment. In the state of the IC card sleeve case 100, the conductive layer 18b (aluminum foil) is located on the back surface 82 side, and the magnetic material layer 18a (layer having high magnetic permeability) is located on the front surface 81 side with respect to the conductive layer 18b. In the illustrated example (paper surface), the IC card 90 is arranged on the lower side (surface 81 side) of the magnetic material layer 18a.

FIG. 16 schematically shows a communication state (normal state) between the coil 92 of the non-contact IC card 90 (the coil inside the IC card) and the card reader 95 provided with the electromagnetic coil 97. In this normal state, the magnetic flux 70 transmitted from the card reader 95 passes through the coil 92 of the IC card 90, so that induced electric power is generated. As a result, the IC chip in the IC card 90 is activated, and communication with the card reader is started.

FIG. 17 shows a configuration in which a conductive material (for example, a metal sheet) 18b is close to the back surface (rear) of the non-contact IC card 90. At this time, a read error is likely to occur. Specifically, when the conductive material (metal sheet) is close to the coil 92 of the IC card 90, the magnetic flux is attenuated by the reaction magnetic flux due to the eddy current generated for the magnetic flux 70 (image of the magnetic flux "72"). reference). Along with this, the IC card 90 does not generate electricity and communication cannot be started (no reaction), resulting in a reading error.

FIG. 18 shows a state when the magnetic material layer 18a is arranged on the back surface (behind) of the non-contact IC card 90 and the conductive layer 18b is arranged behind the magnetic material layer 18a. At this time, even if the conductive layers 18b are close to each other, an error is unlikely to occur (it tends to be in a normal state), and the function is restored. Specifically, even if the IC card 90 and the conductive material (conductive layer 18b) are close to each other, the magnetic material layer 18a is interposed between the IC card 90 and the conductive layer 18b, so that a magnetic flux can escape. (See the image of the magnetic flux "75") As the magnetic flux 70 passes through the coil 92, an induced electric force is generated in the coil 92, and as a result, the IC chip 90 starts communication. In other words, the electromagnetic interference prevention sheet 18 (18a, 18a) of the present embodiment exhibits the function shown in FIG.

As a premise of the communication experiment of the non-contact IC card 90, the Type A / B method may be more prone to error than the FeliCa method. Until now, the FeliCa method was the majority in Japan, so even if there were few communication problems, there is a possibility that communication problems will increase as the Type A / B method becomes more widespread in Japan. The possibility is increasing year by year. Further explaining, it is said that the type A / B system, which is the mainstream overseas, has a heavy (slow) response of the communication system, and the conditions become complicated due to the complexity of the encryption processing and the difference in the required power of the chip. It tends to be. In addition, it is often greatly affected by the use and output of card readers for equipment set in retail stores and service industries. For example, weak radio wave card readers set in convenience stores and IC cards with heavy reactions. In the case of the combination of, there is a high possibility that the reaction cannot be completed (an error occurs) due to insufficient electromotive force. Considering such a possibility, a structure (IC card sleeve case structure) that can communicate with the card reader more efficiently is required.

In this experiment, three different non-contact IC cards 90 were placed in a predetermined position in a wallet, and the wallet was closed with the target IC card (IC card to be read) placed in the foreground. I made a non-contact settlement as it was. The contactless payment test is the terminal (card reader) of the following tests A to C.
(A) Test A: Osaka Metro (Osaka Subway) / JR ticket gate (FeliCa)
(B) Test B: AEON Shopping Center (FeliCa)
(C) Test C: Lawson (convenience store) (Type A / B)

As a preliminary verification, the results of an experiment using only the IC card body without using the IC card sleeve (100) are shown.
(A) Test A: Success 2 times / 9 times (success probability 22%)
(B) Test B: Success 1/5 times (success probability 20%)
In this test (preliminary verification), errors (reading error / communication error) frequently occurred due to insufficient voltage or authentication failure due to the overlap of multiple IC cards.

As a first sample, an experiment was conducted using an IC card sleeve of the conductive layer 18b without the magnetic material layer 18a (an example close to FIG. 17).
(A) Test A: Success 0 times / 3 times (success probability 0%)
(B) Test B: Success 0 times / 2 times (success probability 0%)
In this test, communication (communication) was not possible due to interruption due to magnetic flux attenuation (read error / communication error only).

As a second sample, an experiment was conducted using an IC card sleeve 100 provided with the electromagnetic interference prevention sheet 18 shown in FIG. Specifically, a magnetic material layer 18a, a conductive layer 18b, and an electromagnetic interference prevention sheet 18 having a glue margin 18c of 2 mm were used.
(A) Test A: Success 14 times / 15 times (success probability 93%)
(B) Test B: Success 4 times / 5 times (success probability 80%)
(C) Test C: Success 0 times / 5 times (success probability 0%)
In this test, the probability of success in the FeliCa method is high, and there is a high possibility that such read errors and communication errors will be tolerated. On the other hand, payment could not be made with the Type A / B method.

As a third sample, an experiment was conducted using an IC card sleeve 100 provided with the electromagnetic interference prevention sheet 18 shown in FIG. Specifically, a material having a magnetic material layer 18a, a conductive layer 18b, and an electromagnetic interference prevention sheet 18 having no glue margin 18c (0 mm) was used.
(A) Test A: Success 10 times / 10 times (success probability 100%)
(B) Test B: Success 5 times / 5 times (success probability 100%)
(C) Test C: Success 5 times / 5 times (success probability 100%)
In this test, payment was successful in all tests including FeliCa method and Type A / B method.

Therefore, by using the IC card sleeve 100 provided with the electromagnetic interference prevention sheet 18 (those having no glue margin 18c or those having substantially no glue margin) shown in FIG. 13, three non-contact IC cards can be reliably obtained. Even if they are stacked (among them, the target IC card (IC card to be read) is placed in the IC card sleeve 100 in the foreground), non-contact payment can be performed. As can be seen from this experiment, the structure in which the end portion of the magnetic material layer 18a is formed on the entire surface so as to reach the end portion of the electromagnetic wave interference prevention sheet 18 is a path for magnetic flux as shown in FIG. (See the image of the magnetic flux "75"), and even in the Type A / B method, the IC chip 90 can reliably perform communication.
