[Industrial applications]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage case for magnetic prevention and static elimination for storing magnetic cards such as tickets, commuter passes, credit cards, cash cards, bankbooks, floppies, magnetic printing chips, IC cards and the like.

[Prior art]

In the recent computer society, various types of cards such as cash cards, shopping cards, various members' cards, bankbooks, commuter passes, etc. are circulated and becoming indispensable in daily life. These cards have data stored by selective magnetization on a magnetic stripe whose surface is coated with a magnetic material.
It is a so-called magnetic card. This magnetic card has advantages such as easy handling of the card and low cost, but has a limitation in expanding the function because of its small storage capacity. Therefore, an IC card has emerged as a multifunctional card that has a very large storage capacity by overcoming the limitations of magnetic cards. This IC card is said to be a next-generation multi-function card having a semiconductor integrated circuit and having an arithmetic function and a memory function. Since magnetic cards or IC cards are rapidly becoming widespread, it is necessary to carry or store them. In particular, they are stored in a bag, a wallet, or a card case made of cloth or leather for carrying. It is usually done.

[Problems to be solved by the device]

However, while the magnetic cards or IC cards as described above are important in daily life,
There is a problem that cards are unusable if they are stored or carried incorrectly. That is, although magnetic cards and IC cards are extremely convenient products, they are known to be vulnerable to the effects of magnetism and static electricity, in particular, magnetic cards are vulnerable to magnetism and IC cards are vulnerable to static electricity. . For example, when a plastic case or the like is contained in a portable bag that stores magnetic cards or IC cards and the case is charged, static electricity is generated by the case, and a discharge current flows especially from the MOS type IC chip. There is a defect that the chip is destroyed, and the magnetic data is misread due to dust absorption by static electricity.In addition, the magnetism of the telephone card, the magnetism of the headphone of the radio cassette, or the magnetism of the magnetic health tool and the electric field of the card etc. There is a big problem that the data of the cards are destroyed due to the interaction with each other and the malfunction occurs. Therefore, the present invention was developed for the purpose of protecting the above-mentioned important magnetic type cards and the like from magnetism and static electricity. Only by storing the magnetic cards or IC cards in the case. It is an object of the present invention to provide a storage case that prevents magnetism, eliminates static electricity and can be used safely for a long period of time, and that allows easy insertion and removal of cards. "Constitution of device"

[Means for Solving the Problems]

In order to achieve the above object, the present invention provides leather, synthetic leather,
Form a case body with front and back ports on one side with front and back sheets made of cloth or polyvinyl chloride, and insert a magnetic prevention foil between the front and back sheets of this case body, and appropriately One end side of the conductive sheet member having the length of 1 is fixed to one outer surface position of the back sheet, and the lead-out portion is provided on the other end side of the conductive sheet member. Further, it is preferable to use an iron foil for the above-mentioned magnetic prevention foil, and it is preferable to use a conductive cloth formed by knitting conductive fibers for the conductive sheet member. Further, it is preferable to interpose a core material between the front and back sheets of the case body and the magnetic prevention foil. It should be noted that it is convenient to provide a simple snap on the drawer of the conductive sheet member and on the outer surface of the upper part of the case body so that the case can be covered when the card is stored.

[Action]

Since the present invention is configured as described above, when the conductive sheet member having an appropriate length is pulled out from the case body, the card member and the conductive sheet member fixed to one outer surface position of the back sheet are attached to the case body. Since it is taken out from the door, it is not only convenient to handle as a case, but it is taken out without friction between the inner surface of the case body and the card member, so there is no risk of static electricity being generated at the time of taking out, and the card member Even if static electricity is discharged outside the battery, the discharge current flows through the conductive sheet member and is discharged. Moreover, since the anti-magnetic foil is interposed between the front and back sheets of the case body, the electrostatic shield is provided by blocking the interaction between the magnetism of the magnetic device outside the case body and the electric field in the card member. The magnetic protection of the card member can be achieved without destroying the data of the card member. When the insertion end of the card member is inserted into the case body together with the conductive sheet member, the card member is housed inside the case body, and the conductive sheet member is covered on both sides of the card member to charge the card member. It is possible to eliminate static electricity that is being generated.

【Example】

An embodiment of a storage case for preventing magnetism and static electricity in the present invention will be described below with reference to the drawings. As shown in FIG. 3, a rectangular surface sheet 1 is formed from a material such as leather, synthetic leather, cloth, polyvinyl chloride, etc.
A core material 2 such as a piece of cardboard is fixed, and a magnetic prevention foil 3 made of iron foil coated with a double-sided adhesive is fixed.
A conductive sheet having a back sheet 4 made of synthetic leather, rayon fiber or the like fixed thereto, an edge portion 6 and a fold line 7 provided on the outer periphery of the back surface of the top sheet 1, and having a length substantially equal to that of the top sheet 1. One end of the member 10 is fixed to the end of the backsheet 4 by means of sewing, welding or the like. A lead-out portion 14 is provided at the other end of the conductive sheet member 10, and the simple snap 1 is provided at a position near the inlet / outlet 9 of the topsheet 1 and the lead-out portion 14.
