3. The electronic device case of claim 1 , wherein each of the first magnet and the second magnet is a bar magnet, and
wherein, in the third state, the first magnet and the second magnet are positioned such that a surface of the portion of the first magnet and a surface of the portion of the second magnet are parallel to each other.
4. The electronic device case of claim 1 , wherein in the first state and the second state, the first magnet and the second magnet are positioned such that a surface of the portion of the first magnet and a surface of the portion of the second magnet face different directions.
5. The electronic device case of claim 1 , wherein the first magnet comprises a first groove provided in a surface thereof, and the first connection part comprises a first protrusion inserted in the first groove of the first magnet, and
wherein the second magnet comprises a second groove provided in a surface thereof, and the second connection part comprises a second protrusion inserted in the second groove of the second magnet.
6. The electronic device case of claim 5 , wherein the first groove of the first magnet is offset from a center of the first magnet, and
wherein the second groove of the second magnet is offset from a center of the second magnet.
7. The electronic device case of claim 1 , further comprising an opening/closing sensor provided on the first connection part and configured to generate different signals according to the first state, the second state, and the third state based on a change in a magnetic field.
8. The electronic device case of claim 1 , further comprising a foreign material storage space provided between the first connection part and the second connection part.
9. The electronic device case of claim 8 , wherein a first surface of the second connection part protrudes farther than a second surface of the second magnet such that the foreign material storage space is surrounded by the first connection part, the second connection part, and the second magnet.
10. The electronic device case of claim 1 , further comprising a first buffer member provided on least one of the first connection part and the second connection part at a position corresponding to where the first connection part and the second connection part are in contact with each other in the first state.
11. The electronic device case of claim 1 , further comprising a second buffer member provided on at least one of the first connection part and the second connection part at a position corresponding to where the first connection part and the second connection part are in contact with each other in the second state.
12. The electronic device case of claim 1 , further comprising a hinge shaft,
wherein each of the first magnet and the second magnet has a hole at a central portion thereof and through which the hinge shaft passes,
