Apparatus with rotor input detection, and electronic device including apparatus with rotor input detection

An apparatus with rotor input detection, the apparatus comprising:

• a first reactance element disposed at a rotor configured such that at least a part of the rotor rotates around a rotation axis, and disposed at the rotor such that reactance of the first reactance element varies depending on relative rotation between a first portion of the rotor and a second portion of the rotor;
• a second reactance element disposed at the rotor such that reactance of the second reactance element varies depending on a contact or a force applied to a side surface of the rotor;
• and
• a second resonance circuit capacitor disposed at the rotor,
• wherein the first and second reactance elements are configured to detect inputs of different areas of the rotor, and
• wherein the second reactance element includes a second sensing inductor configured such that inductance of the second sensing inductor varies depending on the force applied to the side surface of the rotor to form resonance together with the second resonance circuit capacitor.
