Electronic device case with opening and closing structure

An electronic device case comprising:

• a first body;
• a first connection part coupled to the first body;
• a second body;
• a second connection part coupled to the second body;
• a hinge structure connected to the first connection part and the second connection part;
• an accommodating space formed by the first body and the second body;
• a first magnet disposed within the first connection part;
• and
• a second magnet disposed within the second connection part;
• wherein the electronic device case is transitioned, by a rotational movement of the second connection part with respect to the first connection part, to one of a plurality of states including a first state in which the accommodating space is opened, a second state in which the accommodating space is closed, and a third state between the first state and the second state, and
• wherein, in the third state, the first magnet and the second magnet are arranged such that the second magnet and the first magnet exert a repulsive force to each other.
