The lower and upper magnetic shield plates 125 and 126 are made of steel material, specifically, a cold rolled steel plate (SPCC). The magnetic force generated from the magnet plate 122 by the lower magnetic shield plate 125 And functions to block much of the downward heading.

The magnetic force generated on both sides of the magnetic plate 122 is cut off by the upper magnetic shielding plate 126. As a result, the magnetic force of the magnet plate 122 is directed only toward the upper portion.

Although the material of the magnetic shield plates 125 and 126 has been described as a cold rolled steel sheet in the present embodiment, the present invention is not limited thereto, and any material can be used as long as it has a function of shielding a magnetic field.

As described above, the upper and lower portions of the main layer 121, into which the magnet plate 122, the upper magnetic shield plate 126 surrounding the magnet plate 122, and the lower magnetic shield plate 125 stacked on the lower surface are inserted, (123) and the lower layer (124) are laminated and heated and pressed to be integrated.

At this time, in order to improve the assembling property of the magnetic force generating plate 127, an adhesive layer (see 128 in FIG. 7D) is formed by attaching a double-sided tape on the lower magnetic shielding plate 125, The upper and lower magnetic shield plates 126 and 126 are laminated so that the upper and lower magnetic shield plates 125 and 126 are bonded to each other via the adhesive layer.

At this time, the lower magnetic shield plate 125 relatively faces the outer surface 11a of the cover plate 11 so that the magnet plate (122 of FIG. 5) faces the inner surface 11a of the cover plate 11, Side).

The second magnet type reinforcing plate 130 according to the embodiment of the present invention is similar to the first magnet type reinforcing plate 120 described above with respect to the second magnet type reinforcing plate 130 built in the middle portion of the back plate 12 of FIG. 30 in the same size and the same position.

At this time, the lower magnetic shielding plate 135 is positioned in the direction of the inner surface 12a of the backplate 12 such that the magnet plate 132 is relatively positioned on the outer surface of the backplate 12, that is, Facing the floor.

3, when the cover plate 11 is folded and bent, the lower magnetic shield plate 125 of the first magnet type reinforcing plate 120 is attached to the second magnet type reinforcing plate 130 of the back plate 12 The magnet plate 132 can be magnetically coupled to each other.

In this case, as shown in FIG. 4, when the cover plate 11 is completely tilted, the magnet plate 122 housed in the first magnet type reinforcing plate 120 is guided to the back surface of the portable device through the lower magnetic shield plate 125 The intensity of the magnetic field applied to the portable device can be greatly reduced through the lower magnetic shielding plate 125. FIG.

Such a method is generally known in the art described in the above-mentioned Japanese Patent Application No. 10-1274572, Do.

However, since the present invention has a configuration unique to the manufacturing method of the magnetic force generating plate 127, the following description will focus on this.

First, as shown in Fig. 7A, a double-sided tape 2 is attached to one surface of a first sheet 1 of SPCC material to form an adhesive layer. The double-sided tape 2 is attached to the surface of the first sheet 1 in a state in which the release sheets on one side are removed, since the upper and lower release sheets are attached to each other with the adhesive layer interposed therebetween.

As shown in Fig. 7B, the first sheet 1 to which the double-sided tape 2 is attached is punched with a press machine or the like to mold the lower magnetic shield plate 125. Fig. A double-sided tape 128 'is molded in the same shape and attached to the surface of the molded lower magnetic shield plate 125.

Alternatively, as shown in FIG. 7C, the second sheet 3 of steel sheet material is punched to form an upper magnetic shield plate 126 having a shape matching the lower magnetic shield plate 125, The shield plate 126 is punched so that the magnet plate insertion holes 126a are formed so as to pass through the upper and lower portions at the same time.

When the lower magnetic shield plate 125 and the upper magnetic shield plate 126 are prepared as described above, the release sheet is removed from the double-faced tape 128 'on the lower magnetic shield plate 125, The shielding plate 126 is adhered to the lower magnetic shielding plate 125 via the adhesive layer 128 formed on the lower magnetic shielding plate 125.

7E, the magnet plate 122 provided in a separate mold is inserted into each magnet plate insertion hole 126a of the upper magnetic shield plate 126, and the lower magnet plate 122 is inserted into the magnet plate insertion hole 126a through the adhesive layer 128, And adheres on the shielding plate 125.

7F, the magnetic force generating plate 127 to be obtained by the above-described method has a magnetic force generating plate insertion hole (not shown) formed in the prepreg sheet 4 as a raw material of the main layer (121 in FIG. 6) (121a ').

As shown in Fig. 7G, the prepreg sheets 5 and 6, which are the raw materials of the upper and lower layers (123 and 124 in Fig. 6) of the prepreg sheets, Are laminated on the upper and lower surfaces of the prepreg sheet (4), and they are integrated by heating and pressing.

7H, the final product, that is, the magnetic reinforcing plate 120 is formed by CNC or the like.

The magnet plate 122 is inserted into the magnet plate insertion hole 126a in the manufacturing process of the magnetic force generating plate 127. However, according to the process, the magnet plate 122 is magnetized in the state of the ferromagnet before magnetization, The magnetization of the magnetic reinforcing plate 120 is inserted into the fitting hole 126a and magnetization may be performed in a final step, that is, a magnetic force is applied by applying a magnetic field after the magnetic reinforcing plate 120 is formed.

Therefore, in the present embodiment, the magnet plate 122 is not necessarily limited to a magnet that is already magnetized in the magnet plate insertion hole 126a, but should be understood to mean a ferromagnet before being magnetized. .

Since the portable case including the magnetic reinforcing plates 120 and 130 and the manufacturing method thereof and the magnetic reinforcing plates 120 and 130 described above is only one embodiment for facilitating understanding of the present invention, It is difficult to understand that the scope of the invention and the technical scope of the invention are limited to those described above.

The scope of the present invention is defined by the appended claims and their equivalents.
