Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an IC card case that protects an IC card from static electricity.

[0002]

[Prior Art]

 Conventionally, a case coated with a conductive material has been used as a case for protecting an IC card from static electricity. As this conductive material, a material to which carbon black is added is used, and it is made by forming a carbon layer on the surface of the case (JP-A-3-43385).

[0003]

[Problems to be solved by the device]

 However, in the case of the above IC card, the black itself of carbon black causes the case itself to be blackish, so that it is poor in decorativeness and a beautiful product cannot be provided.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an IC card case that is rich in decorativeness and is sufficiently protected from static electricity. ..

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the inventor of the present invention welds a rectangular backside sheet and a pocket sheet to the upper side of the pocket sheet by welding the overlapped peripheral edges of both sides and the bottom. The synthetic resin material is applied to at least one of the back side sheet and the pocket sheet, and the surface of the fine powder of mica is coated with ultrafine particles of tin oxide and antimony oxide. It is made by kneading a conductive material with high transparency such as a material into a soft sheet, or by using a soft sheet in which the synthetic resin material is used to form a sheet and the outer surface is coated with the conductive material. I devised a case for an IC card.

[0006]

[Action]

 The conductive material with high transparency such as the conductive material coated with ultrafine tin oxide and antimony oxide on the surface of the fine powder of mica described above has the synthetic resin material even when kneaded into the synthetic resin material and used. It does not affect the color tone, and even if a sheet is formed from a synthetic resin material and the surface is decorated with characters and patterns and then the conductive material is applied, the decoration is not affected. Furthermore, it is also possible to apply the conductive material to the surface of a sheet made of a synthetic resin material and then to decorate the applied surface with characters or patterns.

【Example】

 1, 2 and 3 show a first embodiment according to the present invention, in which (10) is an IC card case, which has a horizontally long rectangular back side sheet (11) and a pocket sheet ( 12) and. The pocket sheet (12) is formed by slightly narrowing the vertical length of the back sheet (11) and notching the upper center in a semicircular shape. The IC card case (10) has both sides and bottoms of both sheets (11) and (12) aligned, and the overlapping peripheral edge (13) is welded to the top of the pocket sheet (12). In addition, an opening (14) into which the IC card (A) can be inserted is formed.

The back side sheet (11) and the pocket sheet (12) are both made of a vinyl chloride resin and a conductive material (15) obtained by coating the surface of a fine powder of mica with ultrafine tin oxide and antimony oxide. ) Is kneaded into a soft sheet. Since the conductive material (15) has high transparency, the conductive material (15) is kneaded even if the vinyl chloride resin is colored or the printed portion (16) such as letters and patterns is provided. There is no change in color due to inclusion. Therefore, by forming a case (10) for an IC card using a sheet in which a conductive material (15) having a high degree of transparency is kneaded, an IC card with various vivid colors can be obtained. It is possible to provide the case (10).

Since the IC card case (10) formed as described above has conductivity, the IC card (A) can be sufficiently protected from static electricity. Further, in this embodiment, the back side sheet (11) has a two-layer structure, and a light and hard interlining material such as a hard vinyl chloride resin sheet, a paper chip board or a phenol resin laminated plate is provided between them. Since the (17) is enclosed, the strength of the IC card case (10) itself increases, so that the IC card (A) can be protected against bending.

FIGS. 4, 5 and 6 show a second embodiment according to the present invention, in which (20) is an IC card case, which is a horizontally long rectangular back side sheet (21) and pockets. Sheet (22). The pocket sheet (22) is formed by cutting the rectangle of the back side sheet (21) along a diagonal line in order to facilitate the entry and exit of the IC card (A). In the case for the IC card, the side portions and the bottom portions of both sheets (21) and (22) are aligned, the overlapping peripheral edge portion (23) is welded, and the IC sheet is attached to the upper portion of the pocket sheet (22). The opening (24) into which the card (A) can be inserted is formed.

The back side sheet (21) and the pocket sheet (22) are both soft sheets made of vinyl chloride resin, and a printing portion (26) such as letters and patterns is provided on the surface thereof. After that, the conductive material (25) in which the surface of the fine powder of mica powder is coated with ultrafine tin oxide and antimony oxide is applied to the inner portion excluding the welded portions on the side and bottom portions. Since the conductive material (25) has a high degree of transparency, characters or patterns are printed on the surface of the colored soft sheet of vinyl chloride resin, and the conductive material (25) is applied over it. However, the hue of the soft sheet does not change, and printed characters and patterns do not become unclear. Therefore, since the conductive material (25) having high transparency is used, the IC card case (20) that protects the IC card from static electricity and is decorated with vivid colors and vivid characters and patterns (20) ) Can be provided.

7, 8 and 9 show a third embodiment according to the present invention, in which (30) is an IC card case, which is a vertically long rectangular back side sheet (31) and pockets. Sheet (32) for use. The pocket sheet (32) is formed by slightly narrowing the vertical length of the back sheet (31), and the upper center is cut out in a semicircular shape. The case (30) for the IC card has both sides (31) and (32) of both sides and bottom aligned, and the overlapping peripheral edge (33) is welded to the upper portion of the pocket sheet (32). The opening (34) into which the IC card (A) can be inserted is formed.

Both the back side sheet (31) and the pocket sheet (32) are made of vinyl chloride resin, and the pocket sheet (32) has a surface of mica fine powder on its surface. A conductive material (35) coated with ultrafine tin oxide and antimony oxide is applied, and a printed portion (36) such as letters and patterns is formed on the applied surface. Since the conductive material (35) has a high degree of transparency, even if the pocket sheet (32) is colored, the change in color due to the application of the conductive material (35) does not occur. Therefore, by applying the highly transparent conductive material (35) to form the IC card case (30), it is possible to provide the IC card case (30) having a vivid color. It will be possible.

[0014]

[Effect of the device]

 As described above in detail, the IC card case according to the present invention is composed of a rectangular backside sheet and a pocket sheet, and the overlapped peripheral edges of both sides and the bottom are welded together to form the upper portion of the pocket sheet. An opening is formed in the backside sheet, and at least one of the backside sheet and the pocket sheet is coated with a synthetic resin material on the surface of a fine powder of mica with ultrafine tin oxide and antimony oxide. Since it is made of a soft sheet that is made of a highly transparent conductive material such as a conductive material, it is easy to put in and take out the IC card, and the IC card is sufficiently protected by static electricity. In addition to achieving this, since the conductive material has a high degree of transparency, it does not affect the color, letters, or pattern on the case. Offer is possible.
