ABSTRACT:
An antenna portion46retaining in a tip portion thereof antenna coils49configured to perform wireless communication with an IC card through an electromagnetic coupling is structured to be freely movable forward/backward between a protruding position above a lane and a retracted position in a unit. An antenna head portion48of the antenna unit46protrudes above the lane and the antenna coils49become close to a vehicle on the lane, so that a distance between the driver of a vehicle and the antenna coils49is shortened and the user can present an IC card80inside a communication distance of an antenna without any difficulty.
