Abstract
An antenna portion 46 retaining in a tip portion thereof antenna coils 49 configured 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 portion 48 of the antenna unit 46 protrudes above the lane and the antenna coils 49 become close to a vehicle on the lane, so that a distance between the driver of a vehicle and the antenna coils 49 is shortened and the user can present an IC card 80 inside a communication distance of an antenna without any difficulty.
