Beschreibung
Zusammenfassung:	An electronic apparatus includes a rotatable operation member that can be rotationally operated, a base member, a magnet having alternately magnetized N and S poles and rotatable integrally with the rotatable operation member, and first and second magnetic members disposed so that the magnet is disposed between them in an axial direction of a rotational center axis of the rotatable operation member and having a plurality of comb tooth portions. In the axial direction, the first magnetic member, the magnet, and the second magnetic member are disposed on an opposite side of the base member from the rotatable operation member. A part of an outer circumferential portion of the rotatable operation member is exposed to an outside from an opening provided on an exterior member of the electronic apparatus. The magnet, the first magnetic member, and the second magnetic member are covered with the exterior member.
