PROBLEM TO BE SOLVED: To stop payment through the use of an on-vehicle device according to the desire of a user by providing a key for temporarily stopping adjustment by the on-vehicle device so as to allow the user to change to a paying form excepting for the radio-type on-vehicle device for paying and receiving the toll. SOLUTION: The on-vehicle device 3 is provided with a payment releasing key 63 for releasing a paying form by this on-vehicle device 3. At an exit lane, a vehicle detecting device 51 detects the entrance of a vehicle to transmit the detection of entrance to a control part 50, which controls a third antenna 37 and starts communication inquiry to the on-vehicle device. When the key 63 is turned on to make an answer prohibiting state in spite of recognizing an inquiry from an output lane, CPU 76 of the device 3 does not answer any signal to the part 50. As the answer from the device 3 is not generated, the part 50 judges that the entering vehicle does not load the device 3 (non ETC vehicle) to execute the toll paying/receiving processing by a normal passing ticket. |
