Description

  The present invention relates to a bankbook case for storing a bankbook, and more particularly to a magnetic shield bankbook case for protecting data recorded on a magnetic tape of a bankbook.

  In recent years, mobile phones have rapidly spread, and now the penetration rate exceeds 75%. As mobile phones become widespread, the number of magnetic errors occurring in magnetic recording media such as bankbooks is also increasing. For example, in the case of a bankbook, there is a risk of causing a magnetic error by carrying it in a bag with a mobile phone. A mobile phone usually has an external speaker, and since a permanent magnet is used for the speaker, an external magnetic field leaks from the vicinity of the speaker. Therefore, there is a possibility that the passbook and the mobile phone may contact or approach each other and erase or disturb the magnetic recording layer of the magnetic recording medium. This is particularly noticeable in the case of a magnetic tape with a coercive force of 300 θe (Oersted) (= 24 kA / m), which is the mainstream in the bankbook. When the magnetic tape part comes into contact with a mobile phone, there is a high probability of magnetic data. It was difficult to read.

  The passbook is usually stored in a passbook case, but a thin vinyl passbook case that is generally widely used can hardly be expected to have a magnetic shielding effect. Therefore, there has been conventionally used a cushioning material such as urethane foam resin as a magnetic shielding material. However, in this case, the cellular phone or the like that generates an external magnetic field is in close contact with the passbook case, and when further pressure is applied, the cushion is crushed and the distance to the recording medium is reduced, which has a high effect on the recording medium. There was a drawback.

  Also, there is a conventional case in which a mount with a metal plate is accommodated in the case body. However, in this case, since the mount is thick, there is a difficulty in handling and manufacturing costs of the passbook case. Furthermore, it has been difficult to easily handle various passbook cases for various designs.

  The problem to be solved by the present invention is to provide a magnetic shield passbook case that can securely protect the magnetic data of the passbook and can easily cope with various designs while being a thin passbook case.

  The present invention has been made to solve the above problems, and one aspect of the present invention is a magnetic shield passbook case, a case main body in which two rectangular pieces are connected in a bag shape or a spread shape, And in order to protect the data of the magnetic recording part of the stored passbook, it is characterized by comprising a magnetic shielding material having a thickness of 0.3 mm or less held in each rectangular piece.

  Another aspect of the present invention is characterized in that a magnetic shield passbook case is formed by laminating a plurality of the magnetic shielding materials.

  Another aspect of the present invention is characterized in that the magnetic shield passbook case includes a foamed plastic sheet as the magnetic shielding material.

  In another aspect of the present invention, the magnetic shield passbook case, the case body is made of a transparent or translucent synthetic resin, and the magnetic shielding material is formed on both surfaces of a high permeability material having a thickness of around 0.05 mm. The magnetic shielding material itself or the paper affixed to the magnetic shielding material is subjected to design printing.

  In another aspect of the present invention, the magnetic shield passbook case, the case body is formed in a bag shape in which three sides of the two rectangular pieces are welded or bonded to each other, and the remaining one side is an opening. Each of the rectangular pieces of the case main body is sealed with the rectangular magnetic shielding material that is equal to or larger than the passbook, and the case main body is provided with a texture to prevent the magnetic shielding material from sticking. The magnetic shielding material is formed of a material that attenuates the magnetic flux density of the opposite surface to 15 mT or less when a permanent magnet having a magnetic flux density of 40 mT is brought into contact with the bag. It is characterized in that design printing is performed on the outer surface of the case body.

  Another aspect of the present invention is a magnetic shield passbook case, wherein the case body is formed in a double-spread shape in which the two rectangular pieces are connected to each other at a long side portion and can be folded in two at the long side portion. At least one of the rectangular pieces is provided with a pocket for accommodating a passbook on the inner surface when the case body is folded in two, with the opening facing the long side. Each of the rectangular pieces of the case main body is sealed with the rectangular magnetic shielding material that is equal to or larger than the passbook, and the case main body is provided with a texture to prevent the magnetic shielding material from sticking. The magnetic shielding material is formed of a material that attenuates the magnetic flux density of the opposite surface to 15 mT or less when a permanent magnet having a magnetic flux density of 40 mT is brought into contact with the magnetic shielding material. The surface to be the outer side upon two-folded body is characterized in that the design print is applied.

  Another aspect of the present invention is characterized in that the magnetic shield passbook case is characterized in that the magnetic shielding material is also subjected to design printing on the inner surface when the case body is folded in half.

  Further, according to another aspect of the present invention, in the magnetic shield passbook case, at least one of the rectangular pieces is further provided with a small pocket on the inner surface when the case body is folded in half. There is a special feature.

It is a graph which shows the performance verification result of the magnetic shield bankbook case of the Example of this invention.

  Hereinafter, a magnetic shield passbook case according to an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiments shown below, and various modifications can be made without departing from the technical idea of the present invention.

  FIG. 1 to FIG. 3 are views showing Embodiment 1 of the magnetic shield passbook case of the present invention, FIG. 1 is a perspective view of a spread state, showing a state when the passbook is stored, and FIG. FIG. 3 is a side view seen from the long side in the folded state, and shows a state when the passbook is stored. FIG. 4 is a cross-sectional view of a rectangular piece of the magnetic shield passbook case of this embodiment.

  The magnetic shield passbook case 1 of the present embodiment is a spread type that can be folded in half. That is, the two rectangular pieces 2 and 2 having the same shape are connected to each other at the long side portion, and can be folded in two at the long side portion. Each rectangular piece 2 is formed in a rectangular plate shape slightly larger than the bankbook 3. Each rectangular piece 2 is configured by accommodating a rectangular plate-shaped magnetic shielding material 5 in a transparent case body 4 made of synthetic resin. Each rectangular piece 2 is provided with a pocket 6 for accommodating the passbook 3 on its inner surface when folded in half with its opening directed toward the long side.

  Although not shown in the present embodiment, one or a plurality of magnetic shielding materials 5 may be laminated. When a plurality of magnetic shielding materials 5 are laminated, a higher magnetic shielding effect can be obtained. Moreover, the magnetic shielding effect can be further enhanced by combining the foamed plastic sheet with the magnetic shielding material 5 to increase the spacing loss.

  In the present embodiment, two main sheets 7 and 7 made of synthetic resin having a size of a spread state are overlapped, and the magnetic shielding material 5 is sandwiched and accommodated between the main sheets 7 and 7. The At that time, the two magnetic shielding members 5 and 5 are arranged in the front and back with their long sides separated from each other, along the front and rear end sides 8 and 9 and the left and right end sides 10 and 11 of the main sheet 7. The sheets 7 and 7 are heat-welded or bonded together. In addition, the case body 4 has an auxiliary sheet 12 that is the same as the rectangular piece 2 but has a short length in the front-rear direction on the inner surface when folded in half. Along the front and rear end sides 8 and 9 and the left and right end sides 10 and 11 of the main sheet 7, heat welding or bonding is simultaneously performed. Furthermore, the front-rear direction center part 13 which becomes a fold when the main sheets 7 and 7 are folded in two is also heat-welded or bonded to each other along the left-right direction.

  As a result, rectangular pieces 2 and 2 having the same shape are formed at both front and rear ends, and can be folded in two at the central portion 13. Further, a rectangular magnetic shielding material 5 that is the same as or slightly larger than the passbook 3 is sealed inside each rectangular piece 2. The main sheets 7 and 7 are thermally welded or bonded to each other along the outer periphery of the magnetic shielding material 5 so that the magnetic shielding material 5 is positioned with respect to the main sheet 7. Furthermore, a pocket 6 is formed between the main sheet 7 and the auxiliary sheet 12, and the passbook 3 can be stored in each of them as shown in FIG. Since each pocket 6 has its opening directed toward the center 13 in the front-rear direction, the bankbook 3 is reliably prevented from falling off when the magnetic shield bankbook case 1 is folded in half. In addition, in a state where the passbook 3 is stored and folded in half, the passbook 3 is disposed and protected between the two magnetic shielding materials 5 and 5.

  The case body 4 composed of the main sheet 7 and the auxiliary sheet 12 is preferably formed of a transparent synthetic resin. Moreover, the case main body 4 may be made of a synthetic resin sheet (piece) that is substantially translucent by forming a large number of creases or fine patterns. Although the material in particular is not ask | required, in a present Example, it forms with a polyvinyl chloride (PVC) or an olefin. The case body 4 is preferably subjected to a textured process to prevent sticking of the magnetic shielding material 5 or the like.

  The magnetic shielding material 5 is a rectangular plate material having a thickness of 0.3 mm or less that protects data on the magnetic tape (magnetic recording portion) of the bankbook 3. The magnetic shielding material 5 can attenuate the magnetic flux density on the opposite surface to 15 mT or less when a permanent magnet having a magnetic flux density of 40 mT is brought into contact. Specifically, the magnetic shielding material 5 is a rectangular plate material having a thickness of 0.3 mm or less, which is formed by pasting papers 15 and 15 on both surfaces of a high permeability material 14 having a thickness of around 0.05 mm. ing.

  More specifically, in the magnetic shielding material 5 of the present embodiment, a coated paper 15 having a thickness of 0.125 mm is pasted on both surfaces of an iron plate 14 having a thickness of 0.05 mm, so that the thickness is 0.3 mm. It is formed in the shape of a rectangular paper piece. Each magnetic shielding material 5 is subjected to design printing 16 on one side or both sides as desired. That is, a design (characters, figures / illustrations, symbols, or a combination thereof) is applied by offset printing or the like. The design printing 16 may be monochrome printing, but is preferably color printing. The design printing 16 may be applied directly to the paper 15 constituting the magnetic shielding material 5, but as shown in FIG. 4, a printed material 17 separately applied to coated paper or art paper is pasted on the magnetic shielding material 5. May be. The printed material 17 is preferably the same as or thinner than the thickness of each sheet on both sides of the magnetic shielding material 5.

  In the case of the spread type as in the present embodiment, it is preferable to apply the design print 16 to the outer surface when folded in half. However, the design print 16 is also applied to the inner surface when folded in half. You can also. It goes without saying that what kind of printing is performed on which side is appropriately set.

  FIG. 5 is a perspective view showing Example 2 of the magnetic shield passbook case 1 of the present invention, and shows a state when the passbook 3 and the card 18 are stored. The magnetic shield passbook case 1 of the second embodiment is basically the same as the magnetic shield passbook case 1 of the first embodiment. Therefore, in the following description, the differences between the two will be mainly described, and corresponding portions will be described with the same reference numerals.

  The magnetic shield passbook case 1 of the second embodiment is different from the first embodiment in that two small pockets 19 are further provided on one of the inner surfaces when folded in half. That is, the rectangular sheet 2 on the near side has a pocket sheet that is the same as the rectangular sheet 2 on the inner surface when folded in half, but the front-rear dimension is shorter than the auxiliary sheet 12. 20 is overlapped with the front edge 8 aligned with the main sheet 7 and the auxiliary sheet 12. The pocket sheet 20 is thermally welded or bonded to the main sheet 7 and the auxiliary sheet 12 at the front edge 8 and the left and right edges 10 and 11.

  Further, the pocket sheet 20 is also thermally welded or bonded to the auxiliary sheet 12 linearly along the front-rear direction at the center portion 21 in the left-right direction. Thus, the two small pockets 19 are formed on the left and right with the opening directed toward the center in the front-rear direction. Each small pocket 19 can store a cash card, a transfer card (transfer ticket), and the like.

  FIG. 6 is a perspective view showing Example 3 of the magnetic shield passbook case 1 of the present invention, and shows a state when the passbook 3 is stored. The magnetic shield passbook case 1 of the third embodiment is basically the same as the magnetic shield passbook case 1 of the first embodiment. Therefore, in the following description, the differences between the two will be mainly described, and corresponding portions will be described with the same reference numerals.

  Although the magnetic shield passbook case 1 of the said Example 1 and the said Example 2 was a spread type, the magnetic shield passbook case 1 of the present Example 3 is a bag type. That is, the case body 4 is formed in a bag shape in which three sides of the two rectangular pieces 2 and 2 are heat-welded or bonded to each other and the remaining one side is an opening. At this time, if one rectangular piece 2 is shifted from the other rectangular piece 2 or an appropriate notch is formed in one rectangular piece 2 at the opening of the bag as shown in the illustrated example. The passbook 3 can be easily stored in the bag-like magnetic shield passbook case 1.

  Also in the third embodiment, similarly to the first embodiment, the rectangular magnetic shielding material 5 that is the same as or slightly larger than the passbook 3 is sealed inside each rectangular piece 2 of the case body 4. Yes. In the third embodiment, the design print 16 is usually applied to the outer surface of the bag-like case body 4. However, the design print 16 may be applied to the inner surface of the bag as desired. . Other configurations are the same as those of the first embodiment.

  In the magnetic shield passbook case 1 of each of the above embodiments, a thin coated paper-like magnetic shielding material 5 having a thickness of 0.3 mm or less is used. By arranging magnetic shielding material (high permeability material) 5 that easily absorbs magnetic flux on both sides of the bankbook 3, the magnetic field to the internal bankbook 3 can be weakened and the influence on the magnetic recording data can be reduced. it can.

  FIG. 7 is a graph showing the performance verification results of the magnetic shield passbook case 1 of each of the above examples. This figure shows the verification result of the influence on the passbook magnetic data by the external magnetic field, the broken line shows the case where the passbook 3 is not put in the case, and the solid line shows the magnetic shield passbook case of this embodiment. 1 shows the case where the bankbook 3 is entered.

  Although the magnetic readable level of the magnetic tape of the bankbook 3 by the ATM terminal is slightly different depending on the model, the area above the horizontal broken line in FIG. That is, generally, the reading output of magnetic data can be read if it is 50% or more. Since the magnetic flux density (G) in the vicinity of an external speaker of a general mobile phone is 250G to 450G, the magnetic data cannot be read with a passbook without a case when viewed in that range. When it is put in the magnetic shield passbook case 1, reading is possible. Therefore, if the bankbook 3 is stored in the magnetic shield bankbook case 1 of the present embodiment, even if an external speaker of the mobile phone contacts the magnetic recording part of the bankbook 3, it cannot be recognized by the ATM terminal. There is no fear of becoming.

  By the way, the magnetic shielding bankbook case 1 of the present embodiment uses a non-cushioning material for the magnetic shielding material 5. In addition, the metal plate 14 is provided though it is very thin. Therefore, even when it is in close contact with a mobile phone or the like and further pressure is applied, the effect is exhibited without being crushed. Moreover, since the magnetic shielding material 5 is very thin, it is not bulky even in a female small bag.

  Further, the magnetic shielding material 5 of this embodiment has a paper-like appearance, and the design printing 16 is applied to the magnetic shielding material 5 itself, or the printed material 17 on which the design printing 16 is applied is attached to the magnetic shielding material 5. Attached. And such a magnetic shielding material 5 is accommodated in the case main body 4 formed from a transparent and flexible raw material. Therefore, the design is not impaired. Further, by using a transparent material and using a color design paper in the case body 4, passbook cases of various designs can be provided at low cost.

  By the way, when the case main body 4 is made transparent, even if the design is arranged on the plate surface of the magnetic shielding material 5, the material itself is exposed on the side surface, so that the conventional foam material or cardboard is used. However, none of them could be made substantially transparent from a design standpoint. However, according to the configuration of the present embodiment, the appearance is the same as the coated paper used for ordinary pamphlets and the like, since the thickness is thin and the design is not impaired even when viewed from the side, the case body 4 is made transparent, A variety of designs can be easily accommodated simply by changing the internal printing.

  Conventionally, when the passbook case is made into a color design, a manufacturing method has been adopted in which offset color printing is applied to the case surface and the film is laminated for protection. However, with this method, the number of processing steps is large, and the cost is inevitably high. According to the configuration of the present embodiment, the offset color printing is performed directly on the magnetic shielding material 5 or the offset color printed matter 17 is pasted on the magnetic shielding material 5 and accommodated in the transparent case main body 4, so that it is inexpensive. Can provide passbook cases with various color designs.

  At this time, a bankbook case with only a bank logo has hitherto been the mainstream, but since it can be easily designed in color, it can also be used as a novelty item. In addition, by placing an advertising medium in the design, it is possible to reduce the burden on the company and distribute magnetic shield cases. In other words, it is suitable not only for distribution and sales at financial institutions but also for selling passbook cases with characters or the like at department stores and stationery stores, or for distribution on street corners. Furthermore, an original bankbook case can be produced by applying photographs or illustrations brought in as paper media or electronic data by the individual to the magnetic shielding material 5 and storing it in the case body 4 at the store.

  Furthermore, when the magnetic shield passbook case 1 is a double-spread type, the design can be arranged not only on the outer surface when folded in half, but also on the inner surface. You can get the possible range.

  The magnetic shield passbook case 1 of the present invention is not limited to the configuration of each of the above embodiments, and can be changed as appropriate. For example, in the first embodiment and the second embodiment, the pockets 6 for storing the passbook are provided on both sides which are the inner side when folded in half, but either one is sufficient in some cases. In addition, the formation position, size, number, etc. of the small pockets 19 formed in the second embodiment can be appropriately changed.
