Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a case for a magnetic recording medium, and more particularly, to a case for protecting a recording medium such as a cash card of a bank, a credit card, a member's card, a telephone card, etc. on which information is magnetically recorded.

[0002]

[Prior art]

 The spread of cards has been remarkable in recent years. For example, many kinds of cards such as bank cash cards, credit cards, members cards, telephone cards, etc. are used in large numbers, and even ordinary people carry around several cards. The current situation.

[0003]

[Problems to be solved by the device]

 The above cards are usually carried around in card cases, business card holders, wallets, system notebooks, handbags, etc., but the information recorded on these cards is recorded magnetically. The information recorded on the card is destroyed when it is brought close to various articles containing magnets, such as TVs, speakers, microwave ovens, handbags with magnets, or when exposed to metal detectors in the flying field. There is a risk that Further, with the development of various electric devices, there is an increasing risk that the recording of cards will be destroyed by electromagnetic waves generated from, for example, televisions, computers, mobile phones and the like.

Therefore, an object of the present invention is to provide a technique for protecting information recorded on cards from magnetism generated from devices having various magnets or electromagnetic waves generated from various electric devices.

[0005]

[Means for Solving the Problems]

 The above object is achieved by the present invention described below. That is, the present invention is a case for a magnetic recording medium such as a card in which information is magnetically recorded, in which most of the periphery of the recording medium is surrounded by a material containing a conductive material. It is a characteristic case for magnetic recording media. According to the present invention, there is provided a case for a magnetic recording medium, which protects information recorded on cards from magnetism generated from devices having various magnets or electromagnetic waves generated from various electric devices.

【Example】

 The present invention will be described more specifically with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view showing an example of a card case to which the present invention is applied. This card case has foldable exterior parts 1, 1'corresponding to a front cover and a back cover and the number of sheets bound between them. It is composed of leaf card holders 2 and 2 ', a pocket 4 for inserting a card 3 is formed inside the exterior parts 1, 1', and a pocket 4 for inserting a card is also formed in the central card holders 2, 2 '. Has been done.

In the illustrated example, the pocket 4 is formed only on one surface of the central card holder 4, but a similar pocket can be provided on the back surface thereof. In the illustrated example, one card case can hold four cards, but by providing pockets 4 on both sides of the central card holders 2, 2 ', six cards can be stored.

FIG. 2 is a cross-sectional view of the exterior parts 1 and 1 ′ of FIG. 1. In the card case of the present invention, electromagnetic wave shielding materials 5 and 5 ′ are inserted in the exterior parts 1 and 1 ′. Is configured. This electromagnetic wave shielding material shields the magnetism or electromagnetic waves incident from the outside of the card case, and protects the magnetic recording of the card inside the card case without destroying it.

The electromagnetic wave shielding material used in the above examples is a thin plate obtained by vapor-depositing aluminum on an iron plate, an alloy thin plate of iron and aluminum, vinyl chloride resin in which a conductive material such as carbon black, metal powder or metal fiber is kneaded. Synthetic resin sheet or film, woven cloth or non-woven cloth made by weaving conductive fibers such as metal fibers or carbon fibers, conductive woven cloth or non-woven cloth obtained by impregnating ordinary woven cloth or non-woven cloth with conductive paint is effective. Used for.

These conductive materials are also excellent in antistatic property due to their properties, and the card case or the card is charged when the card is taken in and out, and the discharge destroys the magnetic recording of the card. Nothing. Further, depending on the type of the electromagnetic wave shielding material, coloring and decoration are possible. In the above-mentioned embodiment, the electromagnetic wave shielding material is inserted inside the exterior part. It can also be used as is in the department.

The illustrated example is an embodiment showing one example of the present invention, and the present invention can naturally be applied to a card case for storing a normal card, a business card case, wallets, a system notebook, a handbag, etc. is there. For example, in the case of a business card holder, wallet or the like, the electromagnetic wave shielding material as described above may be laminated on the front and back sides or inside of the leather or woven cloth constituting these. In such a case, a certain degree of flexibility is required for the business card holder or wallet, and thus the flexible conductive sheet, woven fabric or nonwoven fabric as described above is useful.

[0012]

[Effect of the invention]

 According to the present invention as described above, there is provided a magnetic recording medium case for protecting information recorded on cards from magnetism generated from devices having various magnets or electromagnetic waves generated from various electric devices.
