Abstract:
1. A card device with including an antenna feed terminal, comprising: a card case comprising an upper cover, a lower cover, and a side wall connecting the upper cover with the lower cover, the side wall having a through-hole; a circuit board affixed to the lower cover, positioned in an inner space of the card case, and including a circuit having an antenna connection part; an antenna rotatably positioned on an outside of the card case and electrically connected to the circuit formed on the circuit board; an antenna rotating shaft comprising a conductive material on a base end of the antenna from the outside into an inside of the card case in a direction along a surface of the circuit board the the antenna rotating shaft extending through the through-hole formed in the side wall of the card case; a part for supporting the antenna rotating shaft positioned on an inner wall surface of the card case such that an inner portion of the antenna rotating shaft which is inside of the card case is supported within the card case in such a manner that the inner portion of the antenna rotating shaft is apart from the circuit board and is freely rotatable; a feed terminal having elasticity positioned between the inner portion of the antenna rotating shaft located inside the card case and an area of the circuit board facing the inner portion of the antenna rotating shaft, such that the elasticity of the feed terminal provides an urging force against the inner portion of the antenna rotating shaft; the feed terminal is fixed to the antenna connection part of the circuit of the circuit board and is positioned to face the antenna rotating shaft, such that the feed terminal is electrically connected to the circuit of the circuit board and to the antenna rotating shaft; and the feed terminal is urged by the urging force so as to be maintained in electrical contact with the antenna rotating shaft.
