Antenna unit and card processing system
First Claim
1. An antenna unit installed on a roadside portion of a lane where a processing regarding use of a toll road is performed for a vehicle passing through the toll road, the antenna unit comprising:
- an antenna retaining portion retaining in a tip portion thereof an antenna coil configured to perform wireless communication with an IC card through an electromagnetic coupling; and
a drive mechanism configured to freely move said antenna retaining portion backward and forward between a position where said antenna retaining portion protrudes above the lane and a position where said antenna retaining portion is retracted in said unit.

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 an 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.

10. A card processing system which performs a processing regarding use of a toll road for a vehicle passing through the toll road, the card processing system comprising:
-
an antenna unit which has an antenna retaining portion retaining in a tip portion thereof an antenna coil configured to perform wireless communication with an IC card through an electromagnetic coupling, and a drive mechanism configured to freely move said antenna retaining portion backward and forward between a position where said antenna retaining portion protrudes above the lane and a position where said antenna retaining portion is retracted in said unit;
a vehicle stop detecting unit configured to detect a stopping of a vehicle on the lane; and
a control unit configured to control said drive mechanism of said antenna unit so that said antenna retaining portion protrudes above the lane when said vehicle stop detecting unit detects the stopping of the vehicle on the lane. - View Dependent Claims (11, 12, 13, 14)

15. An antenna unit installed on a roadside portion of a lane where a processing regarding use of a toll road is performed for a vehicle passing through the toll road, the antenna unit comprising:
-
an antenna portion which has a plurality of antenna coil configured to perform wireless communication with an IC card through an electromagnetic coupling;
a transceiver configured to perform transmission/reception of signals separately using the antenna coil of said antenna portion; and
a communication control unit configured to select one of said plurality of antenna coil to actively function based on received signals from said transceiver. - View Dependent Claims (16, 17, 18)
