When the passbook 6 is stored in the anti-magnetism passbook case 1 of the first embodiment, the passbook 6 is inserted from the rounded corner of the passbook 6. Even when the passbook 6 is inserted upside down, it is placed in a position corresponding to the magnetic recording layer 7. The two passbook storage units 2 are each provided with two magnetic shields 4 so that the board 4 comes, but when the passbook 6 is inserted, the top and bottom sides are designated when the passbook 6 is inserted. Location.

The passbook storage unit 2 in the opened state according to the first embodiment.
As shown in FIG. 2, the cross section in the up-down direction of the passbook 6 is substantially the same as that of the passbook 6 with three plastic sheets 8a, 8b, and 8c adhered at the peripheral edges and sandwiched between the two plastic sheets 8a and 8b. A backing sheet 5 having the same dimensions and partially pasting the magnetic shield plate 4 at two predetermined positions is attached so that the mount sheet 5 is located on the outer surface side of the passbook case, and the magnetic shield plate 4 is sandwiched. Inside the two plastic sheets 8a and 8b, plastic sheets 8c are adhered on both sides of the fold 3 so that the vicinity of the fold 3 becomes an insertion port of the passbook 6 at the peripheral edge, and the plastic sheets 8b and 8b are joined together. This is a configuration in which a passbook storage section 2 is formed. The position where the magnetic shield 4 is attached to the mount 5 is determined by the position of the magnetic recording layer 7 formed on the passbook 6, and when the passbook 6 is stored in the passbook storage unit 2, the magnetic shield 4 It is stuck so as to come to a position facing the layer 7.

As shown in FIG. 3, the cross section in the left-right direction of the portion where the open magnetic shield 4 is attached according to the first embodiment is such that three plastic sheets 8a, 8b, 8c are bonded at the peripheral edge. At the same time, the two plastic sheets 8a and 8b are adhered to each other at the central fold 3 so that the plastic sheet 8c on both sides of the fold 3 and the plastic sheet 8b opposite to the plastic sheet 8c are connected to the passbook storage section 2.

In this state, a magnetic shield 4 'partially attached to a predetermined position of the backing sheet 5 is attached so that the backing sheet 5 comes to the outer surface side of the passbook case.

In the case of the magnetic passbook according to the present invention, the magnetic shield plate corresponding to the position, size and shape of the magnetic recording layer of the passbook is adapted to be adaptable to the position, size and shape of the magnetic recording layer of the passbook to be stored. Is attached. When the passbook insertion direction and insertion face are specified, only one magnetic shield plate may be attached to each passbook storage unit. In the first and second embodiments, 2
Although the description has been given of the passbook case that can be opened with two passbook storage portions, the shape of the passbook case is arbitrary, and the passbook case may have one non-spread passbook storage portion. In that case, it is necessary to attach a magnetic shield to the magnetic recording layer of the passbook to be inserted into both side plates of the passbook case.

As the magnetic shielding plates 4, 4 ', a thin plate having a thickness of 0.2 to 0.3 mm made of soft iron, silicon steel plate, permalloy, Ni steel, amorphous alloy or the like can be used.
It is preferable to use a material having a small specific gravity, such as permalloy or an amorphous alloy. Since the magnetic shields 4, 4 'are not attached so as to face the entire surface of the passbook, but are only partially attached to areas facing the magnetic recording layers 7, 7', the use area of the magnetic shields 4, 4 'is reduced. Since the weight of the magnetically permeable passbook case 1, 1 'can be reduced, and the magnetically permeable plates 4, 4' are attached to the passbook 6, which is attached to the mount 5 having substantially the same size as the passbook 6, 6 '. In addition, positioning when the magnetic shield plates 4 and 4 'are partially attached is facilitated. Further, the mount 5 functions as a spacer for widening the interval with the external magnetic field.

As the plastic sheet for producing the magnetically proof passbook case, a soft vinyl chloride sheet having excellent flexibility, a foamed sheet made of a polyolefin resin, a foamed sheet made of a polyester resin, or the like is used, and the peripheral portion is thermally bonded. By doing so, it becomes a bag-shaped passbook storage case. Paperboard, synthetic paper, plastic board and the like can be used as the backing paper, but it is preferable to use paperboard having a thickness of about 100 to 300 g / m ² .
