Card device

摘要

A card device includes a card case, a circuit board disposed in the card case, and an antenna rotatably disposed on the outside of the card case. An antenna rotating shaft is disposed on the base end of the antenna and inserted from the outside into the inside of the card case through a through-hole of the card case such that the antenna rotating shaft extends along the surface of the circuit board and is supported within the card case with the inner part of the antenna rotating shaft being spaced apart from the circuit board and the antenna rotating shaft being freely rotatable. A feed terminal having elasticity that urges the feed terminal against the antenna rotating shaft is disposed between the antenna rotating shaft and a part of the circuit board facing the antenna rotating shaft. The feed terminal is fixed to an antenna connection part of a circuit formed on the circuit board facing the antenna rotating shaft. The feed terminal is urged by its elasticity into contact with the antenna rotating shaft.
