By storing and displaying the information in the terminal device 4, there is an advantage that the reception information can be repeatedly displayed and viewed at any time.

When information is transmitted from the base station 3 using weak radio waves in the millimeter wave band, the occupied bandwidth can be increased, so that a large amount of information can be transmitted at high speed. The terminal device 4 can receive and accumulate desired information within a time when the terminal device 4 passes around. In addition, since the receiving antenna can be reduced in size, a printed antenna or the like can be used, and the terminal device 4 can be easily reduced in size. Further, since the attenuation of the radio wave of the millimeter wave is large, it is easy to limit the service area, and even if the transmission frequencies of the distributed base stations 3 are the same, they do not interfere with each other. When the function of a vending machine is not added to the base station 3, the transmitting and receiving unit has a configuration of a microwave band and a millimeter wave band.
Can be easily installed at station heads or road intersections, etc.
Economical system construction can be achieved.

When the function of a vending machine is added to the base station 3, there is an advantage that it is easy to collect a fee for selling information.
In addition, since the user can select and receive desired information from various types of information each time, there is an advantage that diversification of information can be easily dealt with.

Since the terminal device 4 includes a display unit such as a liquid crystal panel and a storage unit such as a semiconductor memory, a large amount of information is received and stored in the storage unit, and the received information is displayed immediately or later. Can be displayed and read. For example, it is possible to receive and accumulate the contents of newspapers, select pages while walking or in a car, display them on a display unit, and read the latest news and the like. In this case, there is an advantage that paper resources can be saved because the newspaper is not printed.

In a case where a configuration is made such that a card can be received by inserting a card into the terminal device 4, the user holding the terminal device 4 cannot simply receive information, but a card such as a prepaid card or a subscriber card can be used. Since the information can be received only when the terminal is inserted into the terminal device 4, there is an advantage that the collection of the sales price of the information becomes easy as in the case of the vending machine.
