Patent ID: 7659854

Claim:
A card device comprising: a card casing housing a circuit substrate; and an antenna which is disposed rotatably at an exterior of the card casing and is electrically connected to an electric circuit provided on the circuit substrate; wherein a side wall of the card casing is provided with a through hole through which an antenna rotary shaft extends, the antenna rotary shaft being disposed at a base end of the antenna and being composed of a conductive material, the antenna rotary shaft extending from the exterior of the card casing towards the interior of the card casing through the through hole, the antenna rotary shaft being disposed along a substrate surface of the circuit substrate in the card casing while being separated from the substrate surface; a section of the circuit substrate that is opposed to the antenna rotary shaft has a feeding terminal fixed thereto, the feeding terminal being electrically connected to the electric circuit of the circuit substrate, the feeding terminal having a pair of antenna-rotary-shaft elastically-pressing portions that sandwich the antenna rotary shaft from opposite sides with elastic forces, the pair of antenna-rotary-shaft elastically-pressing portions being in pressure-contact with the antenna rotary shaft by being in surface-contact with a peripheral surface of the antenna rotary shaft, the antenna rotary shaft being thereby electrically connected to the electric circuit of the circuit substrate via the antenna-rotary-shaft elastically-pressing portions; each of the pair of antenna-rotary-shaft elastically-pressing portions includes a contact surface arranged to be in contact with the antenna rotary shaft; the feeding terminal includes a mounting portion arranged to be fixed to the circuit substrate; and the contact surfaces and the mounting surface are defined by the same surface of the feeding terminal.
