1. An electronic device comprising:
a first body;
a second body configured to rotate about a central axis with respect to the first body;
a flexible coupling member including a first fixing part coupled to the first body, a second fixing part coupled to the second body, and a non-fixing part disposed between the first fixing part and the second fixing part and that is not fixed to the first body or the second body, the flexible coupling member configured to deform when the second body rotates about the central axis with respect to the first body; and
a first sensor coupled to the non-fixing part and configured to output a first detection signal having a first output value that indicates that an open angle between the first body and the second body about the central axis is a reference angle when the non-fixing part deforms.
