Cover for portable electronic device

1. A cover for receiving a portable electric device therein, the electric device having a display screen provided on a front surface thereof, an operating part provided on a rear surface thereof, and at least first and second fixing holes extending from the front surface through to the rear surface and being laterally spaced apart along an edge thereof, the cover comprising:

a front cover plate for covering the front surface of the electronic device;

a rear cover plate for covering the rear surface of the electronic device; and

an attachment member capable of being attached to the edge of the electronic device, the attachment member including at least first and second fixing portions being laterally spaced apart from one another and being sized and shaped for insertion into the first and second fixing holes, respectively, in a front-rear direction, the first and second fixing portions including respective protrusions operating to hook onto respective edges of the first and second fixing holes, wherein

the front cover plate is connected to the attachment member such that a relative angle between the front cover plate and the attachment member is changeable, and

the rear cover plate is connected to the attachment member such that a relative angle between the rear cover plate and the attachment member is changeable.

2. The cover according to claim 1 , further comprising a first connection portion for connecting an edge of the front cover plate and an edge of the rear cover plate, wherein the attachment member is connected to the first connection portion.

3. The cover according to claim 2 , wherein the attachment member is connected to the first connection through a second connection portion extending between the attachment member and the first connection portion.

4. The cover according to claim 1 , wherein the front cover plate and the rear cover plate are connected to the attachment member through a flexible connection member.

5. The cover according to claim 1 , wherein the at least two fixing portions are capable of being respectively fixed to both ends of the lower edge of the electronic device.

6. The cover according to claim 1 , further comprising a retaining portion capable of retaining the attachment member in a posture which the attachment member takes when the electric device is placed on the rear cover plate; and a stand portion for supporting the rear cover plate standing.

7. The cover according to claim 6 , wherein

the attachment member includes an engagement portion,

the retaining portion is formed on the rear cover plate, and

the engagement portion is formed so as to be caught on the retaining portion to thereby restrict the attachment member from moving downward from the rear cover plate standing.

8. The cover according to claim 6 , wherein

the rear cover plate and the front cover plate are connected to each other so as to respectively move to angular position at which outer surfaces thereof face each other, and

the stand portion is provided to an inner surface of the front cover plate.

9. The cover according to claim 2 , wherein the first connection portion is made of a flexible material.

10. The cover according to claim 3 , wherein the second connection portion is made of a flexible material.

11. The cover according to claim 1 , further comprising:

a first connection portion for connecting the front cover plate and the rear cover plate, and;

a second connection portion extending from the attachment member toward the first connection portion, connected to the first connection portion at a first connection position, and connected to the attachment member at a second connection position distant from the first connection position, wherein:

the first connection portion and the second connection portion operate to move with respect to one another about the first connection position, and

the second connection portion and the attachment member operate to move with respect to one another about the second connection position.
