1n to start wireless communication.

The information distribution device transmits distribution information from the antenna 520 to the authenticated portable information terminals 511 to 51n. The information distribution device terminates the transmission of all the distribution information, or the portable information terminals 511 to 51n are connected to the antenna 520 when the person riding the escalator 530 arrives at the next floor and gets off the escalator 530.
If you go out of the service area, the connection will be disconnected.

In this information distribution, the information distributing apparatus also controls the portable information terminal so that one information distributing apparatus does not transmit the same distribution information to one portable information terminal 511 to 51n a plurality of times. The IDs of the type information terminals 511 to 51n are stored, and the portable information terminal 5 having the same ID is stored.
It is necessary to prevent reconnection with 11 to 51n.

According to such an installation example, while moving between floors using the escalator 530, the owners of the portable information terminals 511 to 51n are able to obtain desired information without performing any special operation. Can be obtained, and the information can be stored.

FIG. 8 is a schematic diagram showing another example of installation of the wireless information distribution system according to the present invention.

In FIG. 8, reference numerals 611 to 61n denote posts 6.
A portable information terminal held by a person viewing 30;
0 is an antenna of the information distribution device. The notice 630 is
It is a notice such as a timetable at a station or a poster of a movie theater.

This wireless information distribution system uses a notice 63
This is a one-to-many wireless information distribution system that distributes information by short-range wireless communication to a portable information terminal held by a person who is viewing 0.

When the owner of the portable information terminals 611 to 61n approaches the notice 630 to view the notice 630, the owner installs the portable information terminals 611 to 61n and the vicinity of the notice 630 held by the person. A connection is established between the connected antennas 620.

After establishing the wireless connection, communication is started with the portable information terminals 611 to 61n whose personal information is registered in the information distribution device. While browsing the notice 630, the information distribution device transmits information from the antenna 620 to the authenticated portable information terminals 611 to 61n. The information distribution device disconnects the connection when all the information has been transmitted, or when the portable information terminals 611 to 61n in communication go out of the distribution area of the antenna 620.

In this information distribution as well, the information distributing apparatus operates so that one information distributing apparatus does not transmit the same distribution information a plurality of times to one portable information terminal 611 to 61n. The IDs of the type information terminals 611 to 61n are stored, and the portable information terminal 6 having the same ID is stored.
It is necessary to prevent reconnection with 11 to 61n.

When a plurality of notices 630 are arranged, it is preferable to use a directional antenna so that information can be distributed only to those who are viewing the notices 630 from the front. good. In this case, a function for displaying that information is distributed to the notice 630 is provided, and which notice 630 is used for which portable information terminal 611 to 611-6.
The viewer may know whether the information is distributed to In. For example, a display device is provided for the notice 630,
A method in which the information distribution device reads the owner name or nickname registered in the portable information terminals 611 to 61n and displays the same on the display device is conceivable.

According to such an installation example, the notice 630 is displayed.
, The owners of the portable information terminals 611 to 61n can obtain desired information without performing any special operation, and can keep the information. Become.

Here, the information distributed by the information distribution apparatus may be information written on the notice 630 and / or information accompanying the information. For example, when the display object 630 is a timetable of a station, the timetable and the fare information are used as distribution information, and when the display object 630 is a poster of a movie theater, the distribution start time and introduction information of the movie are used as distribution information.

Further, the wireless information distribution system according to the present invention can be installed on a vehicle such as a bus to wirelessly distribute information such as advertisement information, news and weather forecast while moving.

In all of the embodiments, the portable information terminal is configured to be capable of setting a mode in which a wireless connection with the information distribution device is not established when the owner does not need the information.

[0108]

According to the present invention, portable information can be obtained without having to perform complicated operations while the user is on an elevator or an escalator or while viewing a bulletin board. The terminal can be automatically distributed and held by wireless communication.
