This invention is installed and used on vehicles to automatically pay tolls and other information by performing two-way communication with an automatic toll collection system installed at toll gates such as expressways. It relates to the automatic toll collection device and the in-vehicle antenna module that are used. Background art

An ETC (Electric Toll Collection) is expected to be put into practical use in Japan in the near future as an automatic toll collection system that collects tolls on toll roads such as expressways. In this ETC system, the driver inserts the IC card into the IC card holder of the automatic toll collection device (hereinafter abbreviated as “in-vehicle device”) installed in the vehicle, and the vehicle passes through the toll gate. In this case, two-way wireless communication is performed between the automatic toll collection system installed in the tollgate gate and the onboard machine installed in the vehicle, and the authentication code and other information are sent to the tollgate gate. It transmits the information and provides the driver with necessary information such as tolls and IC card balances, and automatically pays the tolls. The purpose of this automatic toll collection system is to eliminate congestion caused by toll payment at tollgates on toll roads, improve convenience by reducing cash, and reduce administrative costs in toll collection.

Conventional types of automatic toll-collecting in-vehicle devices are, for example, types that are installed in the front window of the vehicle and types that are installed on the dashboard. is there.
