Patent ID: 8363159

Claim:
The electronic apparatus comprising: an exterior member adapted to form an exterior section; an interior member adapted to be fixed to the exterior member; a hollow shaft adapted to be fixed to the interior member; a first rotational operation member adapted to have a shaft section inserted into an inner side of the hollow shaft, and rotate with respect to the hollow shaft; a first holder adapted to rotate integrally with the first rotational operation member; a first contact piece adapted to be fixed to the first holder; a second rotational operation member adapted to rotate with respect to the exterior member between the first rotational operation member and the exterior member; a second holder adapted to rotate integrally with the second rotational operation member; and a second contact piece adapted to be fixed to the second holder; and an electronic substrate adapted to have a first electrode pattern set in contact with the first contact piece and a second electrode pattern set in contact with the second contact piece, wherein the electronic substrate is arranged between the first holder and the second holder in the axial direction of the hollow shaft.
