Case including structure for supporting electronic device

A case configured to be detachably coupled to an electronic device, the case comprising:

• a base comprising a first surface configured to support the electronic device, a second surface opposite to the first surface, and a supporting surface connecting the first surface and the second surface;
• a hinge disposed on the second surface and defining a rotational axis;
• a moving plate comprising a first supporting member and a second supporting member that is thicker than the first supporting member and configured to be movable with respect to the first supporting member, the moving plate coupled to a first part of the hinge and configured to be rotatable with respect to the base about the rotational axis to position the moving plate in a first state with respect to the base and position the moving plate in a second state with respect to the base;
• and
• a connecting plate coupled to a second part of the hinge,
• wherein, in the first state, an inner surface of the first supporting member and the second surface of the base are to parallel each other, and a side surface of the second supporting member and the supporting surface, which is inclined with respect to the rotational axis, face each other, and
• wherein, in the second state, a direction in which the inner surface of the first supporting member is facing is inclined with respect to a direction in which the second surface is facing, and
• wherein, in the second state, by a movement of the second supporting member with respect to the first supporting member, the side surface of the second supporting member faces the inner surface of the first supporting member or a side surface of the first supporting member perpendicular to the inner surface.
