Patent ID: 8680418

Claim:
A rotation operating device provided on a circuit board, comprising: a rotation operating member provided on the circuit board so as to be rotatable around an axis in a direction substantially parallel to a normal direction of the circuit board; a rotation detection switch provided on the circuit board and detecting rotation of the rotation operating member; and an operational feedback imparting mechanism for imparting operational feedback to a user by intermittently activating in conjunction with rotation of the rotation operating member, wherein the rotation operating member includes an inner circumferential surface surrounding an interior space, and both the rotation detection switch and the operational feedback imparting mechanism are positioned within the interior space; the rotation detection switch includes a rotation sensor capable of an undulating action and a switch main body outputting a detection signal for each undulating action of the rotation sensor; and the rotation operating member comprises: a switch operator having a shape causing the rotation sensor of the rotation detection switch to intermittently undulate in conjunction with rotation of the rotation operating member; and an operational feedback generator formed on an inner circumferential surface of the rotation operating member at a position spaced from the switch operator at least in a direction parallel to an axis of rotation of the rotation operating member, and having a shape causing the operational feedback imparting mechanism to act in conjunction with rotation of the rotation operating member.
