Abstract

In the present invention, a rear cover 1 of a display part is made of at least a resin material, and a rear cover 4 of an operation part is made of a metal material. Respective plane portions of a front case 2 of the display part and a front case 3 of the operation part are made mainly of a metal material, and at least hinge parts 2 c and 3 c , which are formed on the front case 2 of the display part and the front case 3 of the operation part, are made of a resin material.

Claims (49)

1. A foldable mobile device, comprising:

a case of a display part including a front case of said display part and a rear cover of said display part;

a case of an operation part including a front case of said operation part and a rear cover of said operation part; and

a hinge part connecting said case of said display part and said case of said operation part,

wherein said rear cover of said display part is made of at least a resin material,

said rear cover of said operation part is made of a metal material,

said front case of said display part formed of a resin and a metal material, a planar portion of said front case of said display part formed of only said metal material and surrounded on a periphery of said planar portion by said resin, and

said front case of said operation part formed of said resin and said metal material, a planar portion of said front case of said operation part formed of only said metal material and surrounded on a periphery of said planar portion by said resin.

2. A foldable mobile device, comprising:

a case of a display part including a front case of said display part and a rear cover of said display part;

a case of an operation part including a front case of said operation part and a rear cover of said operation part; and

hinge parts connecting said case of said display part and said case of said operation part,

wherein said rear cover of said display part is made of at least a resin material,

said rear cover of said operation part that is only made of a metal material, and

respective plane portions of said front case of said display part and said front case of said operation part are made of only a metal material, and a periphery of said respective plane portions including at least said hinge parts formed on said front case of said display part and said front case of said operation part of a resin material.

3. The foldable mobile device according to claim 1 ,

wherein said rear cover of said display part is made of a composite material comprising a resin and a metal.

4. The foldable mobile device according to claim 1 ,

wherein an antenna part is disposed at portions that are made of a resin material that is used in said rear cover of said display part and said front case of said display part.

5. The foldable mobile device according to claim 1 ,

wherein said case of said display part is made relatively lighter in weight than said case of said operation part.

6. The foldable mobile device according to claim 2 ,

wherein said rear cover of said display part is made of a composite material comprising a resin and a metal.

7. The foldable mobile device according to claim 2 ,

wherein an antenna part is disposed at portions that are made of a resin material that is used in said rear cover of said display part and said front case of said display part.

8. The foldable mobile device according to claim 2 ,

wherein said case of said display part is made relatively lighter in weight than said case of said operation part.

9. A method for manufacturing a case of a foldable mobile device comprising a case of a display part including a front case of said display part and a display part's rear cover, a case of an operation part including a front case of an operation part and a rear cover of an operation part, and a hinge part connecting said case of said display part and said case of said operation part, comprising:

forming said rear cover of said display part of at least a resin material;

forming said rear cover of said operation part of a metal material;

forming said front case of said display part of a resin and a metal material, a planar portion of said front case of said display part formed of only said metal material and surrounded on a periphery of said planar portion by said resin, and

forming said front case of said operation part of said resin and said metal material, a planar portion of said front case of said operation part formed of only said metal material and surrounded on a periphery of said planar portion by said resin.

10. A method for manufacturing a case of a foldable mobile device comprising a case of a display part including a front case of said display part and a rear cover of said display part, a case of an operation part including a front case of said operation part and a rear cover of said operation part, and hinge parts connecting said case of said display part and said case of said operation part, comprising:

forming said rear cover of said display part of at least a resin material;

forming said rear cover of said operation part such that it is only made of a metal material; and

forming respective plane portions of said front case of said display part and said front case of said operation part of only a metal material, and

forming a periphery of said respective plane portions including said hinge parts on said front case of said display part and said front case of said operation part of a resin material.

11. The method for manufacturing a case of a foldable mobile device according to claim 9 ,

wherein said rear cover of said display part is made of a composite material comprising of a resin and a metal.

12. The method for manufacturing a case of a foldable mobile device according to claim 9 , further comprising:

disposing an antenna part at portions made of a resin material used in said rear cover of said display part and in said front case of said display part.

13. The method for manufacturing a case of a foldable mobile device according to claim 9 ,

wherein said case of said display part is formed to be relatively lighter in weight than said case of said operation part.

14. The method for manufacturing a case of a foldable mobile device according to claim 10 ,

wherein said rear cover of said display part is made of a composite material comprising of a resin and a metal.

15. The method for manufacturing a case of a foldable mobile device according to claim 10 , further comprising:

disposing an antenna part at portions made of a resin material used in said rear cover of said display part and in said front case of said display part.

16. The method for manufacturing a case of a foldable mobile device according to claim 10 ,

wherein said case of said display part is formed to be relatively lighter in weight than said case of said operation part.
