Description

  The present invention relates to a storage case for storing a non-contact type IC card and an electronic device capable of reading data in a non-contact manner, and particularly to an IC chip mounted on the non-contact type IC card and the electronic device. The present invention relates to a technique for increasing the security of data recorded in a computer.

  2. Description of the Related Art A non-contact type IC card capable of reading data in a non-contact manner is used for various purposes such as management of entry and exit, cash cards, credit cards, and tickets for convenience. In recent years, the function of this non-contact type IC card is mounted on an electronic device such as a mobile phone so that data can be read and written in a non-contact manner as in the case of the above-mentioned IC card and used as electronic money or a ticket. Tend to be. A non-contact type IC card is equipped with an IC chip and a transmitting / receiving antenna for transmitting / receiving data recorded on the IC chip, and transmits an induced electromagnetic wave radiated from the reader / writer device side to the IC card for transmitting / receiving. It is received by an antenna coil as an antenna, and the induced electromotive force generated by the antenna coil is used as driving power of the IC chip, and is mounted on a non-contact type IC card or electronic device by an electromagnetic wave superimposed on the induced electromagnetic wave. The data recorded on the IC chip is read.

Such non-contact type IC cards and electronic devices are often carried in storage cases. For example, Patent Document 1 below discloses a storage case for storing a non-contact type IC card. This storage case is configured by stacking a plurality of plastic films, and a non-contact type IC card is stored between the plastic films.
JP 2001-118039 A

  Incidentally, an IC chip mounted on such a non-contact type IC card often stores data such as personal information. However, such a non-contact type IC card can read and write data of an IC chip without contacting the reader / writer device, and the distance between the IC card and the reader / writer device is several mm due to the close contact type. It is possible to read and write data recorded on an IC chip even if the remote type is at a distance of about 1 m. For this reason, there has been a problem that data such as personal information recorded on an IC chip mounted on a non-contact type IC card is leaked or falsified. In particular, in a crowd such as in a train, when approaching the owner of a non-contact type IC card, using a small reader / writer device, the non-contact type IC card is recorded on the clothes without directly touching the non-contact type IC card. There are problems such as theft of existing data without the owner's knowledge and the misuse of data such as personal information, and a quick response to theft prevention by a simple method is required. A similar problem occurs in a non-contact electronic device having the same function as a non-contact IC card.

  In view of the above, the present invention provides a storage case capable of preventing leakage or tampering of data such as personal information recorded on the non-contact type IC card or electronic device only by storing the data therein, by electromagnetic waves. With the goal.

  The storage case of the present invention is a storage case for storing a non-contact type IC card or an electronic device capable of reading data in a non-contact manner. An electromagnetic wave shielding means for shielding an electromagnetic wave by covering a type IC card or an electronic device. The electromagnetic wave shielding means may cover one side of the non-contact type IC card or may cover both sides. The electromagnetic wave shielding means may be one that reflects and shields electromagnetic waves or one that attenuates and shields electromagnetic waves. Further, the electromagnetic wave shielding means only needs to attenuate the strength of the non-contact type IC card to a level at which it cannot be driven or a level at which communication cannot be performed.

  According to the present invention, when a non-contact type IC card or electronic device is stored in the storage case, the stored non-contact type IC card or electronic device is covered with the electromagnetic wave shielding means. The recorded data cannot be read or written by electromagnetic waves. Therefore, simply storing a non-contact type IC card or electronic device in the storage case can prevent leakage or falsification of data such as personal information recorded in these cases by electromagnetic waves.

  When the storage case is for storing a non-contact type IC card, it is preferable that the electromagnetic wave shielding means covers both surfaces of the non-contact type IC card when the non-contact type IC card is stored. According to the present invention, since both sides of the non-contact type IC card are covered, electromagnetic waves are shielded on both sides of the non-contact type IC card (see FIG. 3B), and the effect of preventing leakage and tampering is reduced. It can be dramatically increased.

  In the storage case in which the non-contact type IC card or electronic device is stored, it is preferable that the electromagnetic wave shielding means includes a conductive layer containing metal particles and / or conductive carbon particles in a resin component. When the electromagnetic wave shielding means is a metal plate, metal foil, or the like, breakage such as breakage or breakage is likely to occur. According to the present invention, since the electromagnetic wave shielding means is provided with the conductive layer containing metal particles and / or conductive carbon particles in the resin component, the electromagnetic wave shielding means is excellent in flexibility and flexibility, and cracks and tears during use. Are less likely to be damaged and have excellent durability.

  The conductive layer of the electromagnetic wave shielding means preferably has a surface resistance of 5 Ω / sq or less, and more preferably 1 Ω / sq or less. The electromagnetic wave shielding means has higher electromagnetic wave shielding performance as the surface resistance of the conductive layer is lower. If the surface resistance of the conductive layer is 5 Ω / sq or less, and further 1 Ω / sq or less, sufficient electromagnetic wave shielding performance (shielding performance) can be obtained, and the data recorded on a non-contact type IC card or electronic device can be obtained. Leakage and tampering can be effectively prevented. The lower the surface resistance, the better, and it may be as close as possible to 0Ω / sq.

  Further, the conductive layer of the electromagnetic wave shielding means is characterized in that the metal content in the conductive layer is 10% by mass or more and 98% by mass or less. When the metal content is less than 10% by mass, a sufficient electromagnetic wave shielding effect cannot be obtained, and when the metal content exceeds 98% by mass, the flexibility deteriorates. According to the present invention, since the metal content is 10% by mass or more and 98% by mass or less, a sufficient electromagnetic wave shielding effect is obtained, and the storage case has good flexibility.

  Further, from the viewpoint of preventing leakage and tampering, when a non-contact type IC card or electronic device is stored, a gap between the non-contact type IC card or electronic device and the electromagnetic wave shielding means is within 2 mm, and furthermore, Preferably, they are in close contact. This is applicable to a storage case in which the electromagnetic wave shielding means covers one surface of a non-contact type IC card, a storage case which covers both surfaces, and a storage case in which electronic devices are stored. According to the experimental results, when no electromagnetic wave shielding means is interposed between the non-contact type IC card or electronic device and the reader / writer device (see FIG. 3A), the non-contact type IC card or electronic device and the electromagnetic wave If the gap with the shield means is within 2 mm, and if the gap is in close contact, data cannot be read or written. According to the present invention, since the gap between the non-contact type IC card or electronic device and the electromagnetic wave shielding means is within 2 mm, data cannot be read or written, and leakage and tampering can be reliably prevented. .

  Further, the storage case includes a main body part that forms a storage space for storing a non-contact type IC card and an electronic device, and a cover part that can be freely moved toward and away from the main body part. When the parts are closed so as to be in contact with each other, at least a part of the non-contact type IC card or the electronic device is covered with the electromagnetic wave shielding means, and when the parts are opened so that the cover part is separated from the main body part, the non-contact state is obtained. It is preferable that at least a part of the type IC card or the electronic device is not covered with the electromagnetic wave shielding means.

  The storage case for storing the non-contact type IC card is foldable, and has a storage space for storing the non-contact type IC card inside the folded case. It is preferable that at least a part of the non-contact type IC card is configured to be exposed from the electromagnetic wave shielding means when it is covered with the electromagnetic wave shielding means and opened.

  In the case where the storage case has a cover portion as described above or in the case of a folding type, from the viewpoint of convenience, a non-contact type IC card or electronic device is stored and the cover portion is opened or the folding portion is opened. Sometimes, the gap between the non-contact type IC card or electronic device and the electromagnetic wave shielding means is preferably 3 mm or more. As a result of the experiment, when the electromagnetic wave shielding means is not interposed between the non-contact type IC card or the electronic device and the reader / writer device (see FIG. 3A), the communication between the non-contact type IC card and the electromagnetic wave shielding means is not performed. It was found that if the gap was 3 mm or more, data stored in the non-contact type IC card could be read and written by electromagnetic waves. According to the present invention, when using a non-contact type IC card or electronic device, the cover portion can be opened or folded without removing the non-contact type IC card or electronic device from the storage case. However, after the electromagnetic wave shielding means is not interposed between the reader / writer device and the non-contact type IC card or electronic device, it can be simply moved over the reader / writer device to the non-contact type IC card or electronic device. The recorded data can be read and written by electromagnetic waves, and the convenience in use is improved.

  According to the storage case for storing the non-contact type IC card and the electronic device of the present invention, when the non-contact type IC card and the electronic device are stored in the storage case, the non-contact type IC card and the electronic device become an electromagnetic wave shield. As a result, the data recorded on the non-contact type IC card or electronic device cannot be read or written by electromagnetic waves. Therefore, only by storing a non-contact type IC card or electronic device in this storage case, it is possible to prevent data such as personal information recorded on the IC chip from being leaked or falsified by electromagnetic waves. In particular, for a non-contact type IC card, the effect of preventing leakage and tampering can be drastically improved by covering both sides with electromagnetic wave shielding means. A quick response is desired to prevent data such as personal information from being stolen. However, since it is only necessary to store the data in a storage case, theft can be easily and quickly prevented. Further, as described above, when the storage case is provided with a cover portion or a foldable storage case, it is possible to read and write as necessary while keeping the storage case in the storage case. .

  Hereinafter, a storage case for storing a non-contact type IC card or electronic device of the present invention will be described in detail with reference to the drawings.

(First Embodiment)
FIG. 1 is a perspective view of a storage case 10 according to the present embodiment, and FIG. 1B is a cross-sectional view thereof. The storage case 10 according to the present embodiment is a storage case for storing a non-contact type IC card, and includes an electromagnetic wave shielding means 2 (a front sheet 2a, an inner sheet 2b, and a back sheet 2c). In the present embodiment, the front sheet 2a, the inner sheet 2b, and the back sheet 2c function as an electromagnetic wave shielding means 2 that covers a non-contact type IC card and shields electromagnetic waves.

  The electromagnetic wave shielding means 2 includes a front sheet 2a, an inner sheet 2b, and a back sheet 2c. Each of the sheets 2a, 2b, 2c is a rectangular sheet having a different size. The sheets 2a, 2b, and 2c are overlapped in order of size so that the three sides are aligned, and the three sides are joined by sewing or the like, and the insertion openings 3a and 3b are formed on the other side, and Two storage spaces for storing a non-contact type IC card are formed between the sheets 2a, 2b and 2c. Since the three sides of each of the sheets 2a, 2b, 2c are joined by stitching or the like, not only the front and back surfaces, but also the left and right sides and the side opposite to the insertion ports 3a, 3b are shielded. The insertion openings 3a and 3b only need to be capable of inserting and removing a non-contact type IC card, and for example, may be insertion openings without joining two sides. Further, each of the sheets 2a, 2b, 2c is preferably smaller than a non-contact type IC card. Thus, when the non-contact type IC card is inserted, a part of the non-contact type IC card protrudes from the insertion openings 3a and 3b, and the protruding portion can be picked and taken out.

  FIG. 2A is a cross-sectional view of the electromagnetic wave shielding means 2 (each sheet 2a, 2b, 2c) of the present embodiment. The electromagnetic wave shielding means 2 (each sheet 2a, 2b, 2c) has a two-layer structure in which a conductive layer B for shielding electromagnetic waves is laminated on a base sheet A.

  The base sheet A is a resin film made of vinyl chloride, polyethylene, ethylene-vinyl acetate copolymer, polyolefin, polyester, polyurethane, nylon, or the like, or cotton, hemp, wool, acetate, rayon, polyester, nylon, aramid, or the like. It is a woven fabric, a knitted fabric, a fiber fabric such as a nonwoven fabric, a paper, or the like, and a sheet-like material having excellent flexibility and flexibility.

  The conductive layer B is formed by mixing conductive particles such as metal particles or conductive carbon particles with a resin material, a metal plate such as an aluminum plate, a metal foil such as an aluminum foil, or by vapor deposition or sputtering. Examples include a metal film, a conductive fiber, and a cloth formed using a plated cloth. Among them, as the conductive layer B, a material obtained by mixing conductive particles (metal particles, conductive carbon particles, and the like) with a resin material is preferable. A conductive layer containing conductive particles in a resin material is soft and has excellent bending performance, so that damage such as cracking or tearing during use can be prevented.

  There is no particular limitation on the resin component that is the main component of the conductive layer B. For example, polyurethane-based, polyester-based, polyamide-based, acrylic-based, silicone-based, polyfluorinated, polyethylene-based, styrene-butadiene-based, and nitrile-butadiene-based And synthetic resins such as epoxy resins. These synthetic resins can be obtained in the form of a solution dissolved in a solvent, an emulsion emulsified and dispersed in water, a chip-like solid, and the like.

  Examples of the material of the conductive particles contained in the conductive layer B include metals such as gold, silver, copper, aluminum, nickel, zinc, platinum, titanium, cobalt, beryllium, and palladium, and alloys containing these metals. One having properties. In particular, if an antibacterial metal such as silver is used, an antibacterial and antifungal effect is exhibited. These conductive particles are in the form of powder, and the average particle size is preferably 0.1 to 20.0 μm so that the electromagnetic wave shielding (shielding) effect can be sufficiently obtained. The shape may be spherical, needle-like, scale-like or the like, but is preferably in the form of a scale, and more preferably in a scale-like conductive particle having a smaller average particle diameter compared to the conductive particle. Those containing a small amount of particles are preferred. Since the electromagnetic wave shielding means 2 (each sheet 2a, 2b, 2c) has a higher electromagnetic wave shielding (shielding electromagnetic wave) effect as the surface resistance of the conductive layer B is lower, the conductive particles are scale-like or smaller. When the average particle diameter is mixed, the surface resistance of the conductive layer B can be reduced and the electromagnetic wave shielding effect can be enhanced.

  In addition, the surface resistance of the conductive layer B is preferably 5 Ω / sq or less, and more preferably 1 Ω / sq or less, since the electromagnetic wave shielding function is sufficiently exhibited. Since the electromagnetic wave shielding effect increases as the surface resistance decreases, the lower limit of the surface resistance is preferably as small as possible, and may be as close as possible to 0Ω / sq. The surface resistance can be adjusted by appropriately combining the types and amounts of the above metals, the thickness of the conductive layer, and the manufacturing method described later. Here, the surface resistance is a value measured using a surface resistance measuring instrument in accordance with JIS K-7194. The thickness of the conductive layer B is not particularly limited, but is preferably about 5 μm to 2000 μm from the ease of use as a storage case.

  The metal content of the conductive layer B is preferably from 10 to 98% by mass, more preferably from 50 to 95% by mass, based on the mass of the conductive layer B. Although the preferable range of the metal content differs depending on the metal species, if it is more than necessary, the flexibility is impaired, and if it is too small, the electromagnetic wave shielding effect is not sufficiently exhibited. Further, from the viewpoint of the adhesiveness between the base sheet A and the conductive layer B, the metal content in the conductive layer B is preferably from 50 to 98% by mass, and more preferably from 75 to 95% by mass. More preferred.

  From the viewpoint of both the adhesiveness between the base sheet A and the conductive layer B, and the electromagnetic wave shielding performance, desirable conditions are as follows: a flaky metal as the metal, a urethane resin as the resin component, and a conductive layer B. It is preferable that the metal content in the composition be 80 to 95% by mass. Actually, a conductive layer containing 90% by mass of silver in urethane resin is bonded to the surface of the fiber cloth, and an aluminum foil having a thickness of 80 μm is bonded to the surface of the fiber cloth as a conductive layer. When three types of electromagnetic wave shielding means were manufactured and compared with those obtained by depositing aluminum on the surface of a polyester film, all of them exhibited sufficient electromagnetic wave shielding performance as electromagnetic wave shielding means. Among them, the electromagnetic wave shielding means in which a conductive layer containing 90% by mass of silver in urethane resin is bonded to the surface of the fiber cloth has high flexibility and flexibility, so that breakage and breakage are hardly caused. The durability was good.

  FIG. 2B is a cross-sectional view of another example of the electromagnetic wave shielding means 2 (each sheet 2a, 2b, 2c) of the present embodiment. The electromagnetic wave shielding means 2 has a two-layer structure in which the conductive layer B is formed on the surface of the base sheet A. The conductive layer B is sandwiched between the two base sheets A. Alternatively, a three-layer structure may be used. According to this, since the conductive layer B is protected by the base sheets A, A, the conductive layer B is not damaged even when a non-contact type IC card is taken in and out, and the electromagnetic wave shielding (shielding). The effect can be maintained. The electromagnetic wave shielding means 2 may have a multilayer structure in which a plurality of base sheets A,... A and a plurality of conductive layers B,. Further, as shown in FIG. 2C, a one-layer structure in which a resin material mixed with conductive particles is formed into a sheet without using the base sheet A may be used.

  If the electromagnetic wave shielding means is made by laminating a conductive layer on a sheet-like base material such as fiber fabric such as woven fabric, knitted fabric or non-woven fabric, or paper or film, it can be easily processed into various shapes. It is preferable in terms of strength and design during use and ease of sewing and production. For example, the storage case can be a bag type such as a purse type, a regular type, a drawstring type, or a pocket type which can be attached to clothing, a bag, or the like.

  A usage example of the storage case 10 according to the present embodiment will be described. When the user does not use the non-contact type IC card, for example, when the user places it in a desk at home or at work, or carries it in a bag or pocket, it is stored in the storage case 10. . When a non-contact type IC card is stored in the storage case 10, the non-contact type IC card is covered with the electromagnetic wave shielding means 2 (each of the sheets 2a, 2b, 2c), and the electromagnetic wave from the reader / writer device is shielded. This makes it impossible to read or write data recorded on the non-contact type IC card using electromagnetic waves. Even if data recorded on a non-contact type IC card is likely to be stolen by a reader / writer device due to crowds in a train or the like, electromagnetic waves from the reader / writer device are shielded by the electromagnetic wave shielding means 2, Will not be stolen. A quick response is desired to prevent theft of data such as personal information. However, since it is only necessary to store the information in the storage case 10, theft can be easily and quickly prevented.

  In particular, with respect to a non-contact type IC card, if both sides are covered with the electromagnetic wave shielding means 2 as in the present embodiment, leakage and tampering can be effectively prevented. As shown in FIG. 3B, when both sides of the non-contact type IC card are covered, the induced electromagnetic wave from the reader / writer device is shielded from both sides, so that no induced electromotive force is generated. In addition, reading and writing of data on the IC chip becomes impossible, and the effect of preventing leakage and falsification can be dramatically improved.

(Another Example 1 of First Embodiment)
The storage case 10a of the other example 1 in the present embodiment is an example in which only one side of a non-contact type IC card is covered by the electromagnetic wave shielding means 2. FIG. 4A is a perspective view of the storage case 10a of Example 1, and FIG. 4B is a cross-sectional view thereof. A front side sheet 7a and a back side sheet 7b are connected to both sides of the sheet-like electromagnetic wave shielding means 2 by sewing or the like, and storage spaces 3a and 3b are formed therebetween, and one side has an insertion port. The front sheet and the back sheet are sheets made of leather or resin having no electromagnetic wave shielding effect. In the state where the non-contact type IC card is stored, the gap between the non-contact type IC card and the electromagnetic wave shielding means 2 is within 2 mm, and more preferably, is in close contact. As shown in FIG. 3A, as a result of the experiment, when the gap H between the electromagnetic wave shielding means 2 and the non-contact type IC card is within 2 mm, the distance between the non-contact type IC card and the reader / writer device is reduced. Even if no electromagnetic wave shielding means intervenes, reading and writing become impossible. According to the storage case 10a of Example 1, since the gap H is within 2 mm and is in close contact with each other, even if only one side is covered by the electromagnetic wave shielding means 2, sufficient leakage or tampering is performed. The prevention effect is obtained.

(Another example 2 of the present embodiment)
When the storage case stores a non-contact type electronic device having the same function as the non-contact type IC card, the storage case has a shape suitable for the non-contact type electronic device. For example, when the non-contact type electronic device is a mobile phone, the electronic device has a substantially rectangular parallelepiped shape that covers the mobile phone. FIG. 5 shows a perspective view of a storage case 10b for storing a mobile phone. The storage case 10b is formed into a substantially rectangular parallelepiped shape by joining a plurality of sheet-shaped electromagnetic wave shielding means 2 by sewing or the like, and has an insertion port 3 formed above. It is preferable that the insertion opening 3 be provided with a lid that can be opened and closed, so that the entire mobile phone that is an electronic device is covered by the electromagnetic wave shielding means 2. When carrying a mobile phone, the user inserts and stores the mobile phone through the insertion slot 3 and puts it in a pocket, bag, or the like. When using a mobile phone, take it out of the insertion slot 3 and use it. Since the mobile phone stored in the storage case 10b is covered with the electromagnetic wave shielding means 2, it is impossible to read or write data recorded in the mobile phone by the electromagnetic wave.

(Other Example 3 in the present embodiment)
When various things are to be stored in the storage case, the storage case is made into a bag shape. FIG. 6 shows a bag-shaped storage case 10c. The storage case 10c is a sheet-shaped electromagnetic wave shielding means formed into a bag shape having an insertion port 3 by sewing or the like, and includes a sealing means F for sealing the insertion port 3. The sealing means F is, for example, a string-shaped one that squeezes the vicinity of the insertion opening 3 and then binds it, such as a drawstring bag, or a rubber-shaped one that is attached near the insertion opening 3 and opens and closes by expanding and contracting. But it's fine. Further, the sealing means F may open and close the insertion port 3 by folding back the vicinity of the insertion port, for example, like an envelope. By making the storage case into a bag shape, it is possible to store various non-contact type electronic devices or collectively store non-contact type IC cards and electronic devices without being limited in size, shape or number. I can put it.

(Second embodiment)
As shown in FIGS. 7A and 7B, the storage case 20 according to the present embodiment includes a main body portion 5 that forms a storage space for storing a non-contact type IC card, and is separated from and attached to the main body portion 5. A flexible cover portion 4. The storage case 20 is foldable in the vicinity of the center. One side of the storage case 20 is a main body portion 5 and the other side is a cover portion 4 with the fold line L as a boundary.

  The main body part 5 includes a region on one half of the rectangular sheet-like electromagnetic wave shielding means 2 d and an inner sheet 6. The inner sheet 6 is overlapped on one half of the area with the folding line L of the electromagnetic wave shielding means 2d as a boundary, and three side edges of the inner sheet 6 are joined to the electromagnetic wave shielding means 2d by sewing or the like. And an electromagnetic wave shielding means 2d, a storage space is formed, and an insertion port 3 following the storage space is formed.

  The material of the electromagnetic wave shielding means 2d is the same as that of the electromagnetic wave shielding means 2 of the above embodiment. An opening 6a is provided near the center of the inner sheet 6, and an opening sheet made of a transparent resin film or the like is attached so as to close the opening 6a. The inner sheet 6 and the opening sheet may be made of a material having an electromagnetic wave shielding property or a material having no electromagnetic wave shielding property.

  The cover portion 4 is formed of a region on the other half with the folding line L of the electromagnetic wave shielding means 2d as a boundary. When the cover portion 4 is folded along the folding line L, the cover portion 4 comes into contact with the main body portion 5 and the inner sheet 6 Acts like a lid on When the folded state is released and the state is opened, the cover part 4 is separated from the main body part 5, and a state in which the lid covering the inner sheet 6 is opened is obtained.

  When using the storage case 20, first, a non-contact type IC card is inserted from the insertion slot 3 and stored in the storage space. When a non-contact type IC card is not used, the storage case 20 is folded into two with the folding line L as a boundary. In the folded state, the storage space of the main body portion 5 is located inside the folded state, and the non-contact type IC card stored in the storage space is sandwiched between the electromagnetic wave shielding means 2d so that both sides are covered, Data leakage and tampering are prevented. When a non-contact type IC card is used, the non-contact type IC card is taken out of the storage case 20 and used.

  The opening 6a may not be provided, but it is preferable to provide the opening 6a because the stored non-contact type IC card can be visually recognized from the opening 6a. Further, the opening sheet may not be provided, but it is preferable to provide the opening sheet from the viewpoint of protection of the non-contact type IC card.

  In addition, all of the main body portion 5 is made of a material having no electromagnetic wave shielding effect, only the carver portion 4 is made of a material having an electromagnetic wave shielding effect, and only the cover portion 4 functions as an electromagnetic wave shielding means. good. In use, simply by opening the cover portion 4, the electromagnetic wave shielding means (that is, the cover portion 4) is separated from the non-contact type IC card by 3 mm or more, so that data can be read or written. On the other hand, when not in use, by closing the cover part 4, the gap between the non-contact type IC card and the electromagnetic wave shielding means becomes less than 2 mm (substantially close contact), and only one side of the non-contact type IC card is protected by the electromagnetic wave shielding means. Even if it is covered, a sufficient effect of preventing leakage and tampering can be obtained. That is, the read / write of data recorded on the IC chip can be controlled only by opening and closing the cover portion, and the storage case is excellent in convenience.

(Another Example in Second Embodiment)
As another example in the present embodiment, as shown in FIG. 8, a purse-type storage case 20a in which a space S for separately storing bills and coins is provided in the foldable storage case 20 may be used. According to this, since the storage case 20a can be used as a wallet, the practicality is improved.

(Third embodiment)
FIG. 9A is a perspective view of the storage case 30 of the present embodiment, and FIG. 9B is a sectional view thereof. The storage case 30 stores a non-contact type IC card, and is substantially the same as the foldable storage case 20 of the second embodiment, except that the main body 5 has two storage spaces. A partitioning sheet 8 is provided. The partition sheet 8 is a sheet made of leather, resin, or the like having no electromagnetic wave shielding effect. The partition sheet 8 has three side edges joined to the storage space side surface of the inner sheet 6 by stitching or the like, and the partition sheet 8 is inserted between the inner sheet 6 and the partition sheet 8 from an uninserted upper insertion opening. Can store an IC card. The inner sheet 6 of the main body portion 5 and the electromagnetic wave shielding means 2d are joined via a gusset M. The gusset M is configured such that a predetermined gap is maintained in the gap between the partition sheet 8 and the electromagnetic wave shielding means 2d. The gusset M has a width such that when a non-contact type IC card is stored, a gap H between the non-contact type IC card and the electromagnetic wave shielding means 2d constituting the main body portion 5 is 3 mm or more. Further, the outer portion of the cover portion 4 and the outer portion of the main body portion 5 (that is, the rectangular sheet-shaped electromagnetic wave shielding means 2d) is made of a material having an electromagnetic wave shielding effect and functions as an electromagnetic wave shielding means. Is made of a material having no electromagnetic wave shielding effect. It is preferable that the gusset M has a function as an electromagnetic wave shielding means like the electromagnetic wave shielding means 2d, but only the both surfaces may be covered with the electromagnetic wave shielding means as not having the electromagnetic wave shielding effect.

  When the non-contact type IC card is stored in the storage case 30, the non-contact type IC card is stored between the partition sheet 8 and the inner sheet 6. The stored non-contact type IC card is prevented from moving toward the electromagnetic wave shielding means 2d constituting the main body portion 5 by the partition sheet 8, and the gap H is maintained at 3 mm or more. When a non-contact type IC card is used, the cover portion 4 is opened or folded without removing the non-contact type IC card from the storage case 30 so that the non-contact type IC card can be connected to the reader / writer device. After the electromagnetic wave shielding means 2d is not interposed between the IC cards, the IC card is held over a reader / writer device. Since a gap H of 3 mm or more is formed between the IC card and the electromagnetic wave shielding means 2d, data can be read or written. When the non-contact type IC card is not used, only the cover part 4 is closed, and both sides of the non-contact type IC card are covered with the electromagnetic wave shielding means 2d, so that leakage and tampering are surely prevented. Is prevented. That is, it is possible to control the read / write of data recorded on the non-contact type IC card by electromagnetic waves with a simple operation of simply opening and closing the cover portion 4, thereby improving convenience.
