If the information providing destination has already processed the information into character information, the information is processed as it is. If the information is not processed into the character information, the information is processed into the character information at the operation center and transmitted as a radio wave of the character information from the operation center. Note that an information processing company that processes audio information and the like into textual information may be interposed between the operation center of the vehicle company and an information providing destination such as a television broadcast station. When the temporary information is transmitted from the operation center, it is caught by a receiver D of a running train or the like and stored in a hard disk or a RAM in a computer B installed inside the vehicle. This is to repeatedly transmit the same information into the vehicle. The temporary information is repeatedly transmitted at regular intervals in preference to normal service information. That is, when the temporary information is received by the receiver D, the transmission of the service information is temporarily interrupted, and only the temporary information is transmitted.

As shown in FIG. 10, the head of the temporary information has an ID 31. When the transmission of the temporary information ends, the end ID 32 is transmitted, and then the normal service information is transmitted again.

The personal terminal device body E1 constantly monitors the ID 31 of the temporary information from the receiving module E2, and immediately recognizes the ID 31 of the temporary information, immediately sounds a buzzer that the temporary information has been entered, and alerts the passenger, Temporary information is displayed preferentially.

After viewing the temporary information, if any one of the push buttons 4, 5, and 6 of the personal terminal device body E1 is pressed, the display returns to the original state, and the display of the service information is started again.

Next, a case where a passenger uses the wake-up function using the personal terminal device E will be described.
