Is transmitted through the data transmission / reception unit 162.

  In response to this, on the ticket gate device 2 side, based on the station identifier of Tokyo station acquired by the boarding station acquisition unit 24b by the fare settlement unit 24c and the identifier of the Osaka station where the ticket gate device 2 is installed, The fee is calculated with reference to the fee database 24d and notified to the portable information terminal 1 side. At this time, the fare settlement unit 24c outputs a notification that the calculation of the fare is completed to the dictionary writing unit 24e simultaneously with the notification of the fare to the portable information terminal 1.

  On the other hand, on the mobile information terminal 1 side, the value information stored in the RAM 152 is updated for the calculated fare, or the payment is completed after accessing the network and making a payment to the financial institution. The notification is sent to the dictionary management unit 163, and the dictionary management unit 163 downloads the region specific dictionary. The downloaded region specific dictionary is written in the RAM 152 of the portable information terminal 1.

  After that, the portable information terminal 1 that has passed the ticket gate can create a document using the Osaka dialect conversion dictionary stored in the RAM 152 instead of the standard dictionary written in the ROM 153.

  As for the region-specific dictionary, the user can select whether or not to write the downloaded region-specific dictionary in the RAM 152 by making arbitrary settings for the setting unit 163f. If this is not desired, the writing of the region specific dictionary can be prohibited by setting in advance to that effect.

  When the user gets on the train from Osaka Station and moves to another station, a dictionary specific to the area is downloaded in the ticket gate device at the other station. Further, even when getting off at a station or the like that does not provide such a region-specific dictionary download service, the downloaded region-specific dictionary or the standard dictionary provided by default is sent to the setting unit 163f. Priority setting of which one to use preferentially, setting of how much priority is used to delete region specific dictionary, how much time (hours, days, weeks, etc.) since downloading If the priority is lowered or the dictionary is deleted, it is possible to input using the dictionary according to the user's needs.

(Character input operation)
FIG. 6 and FIG. 7 show a character input procedure using the Osaka dialect region specific dictionary. In the present embodiment, when the user creates a sentence, the LCD 165 displays a sentence input area 165a and a conversion candidate display area 165b vertically.

  For example, as shown in FIG. 6, when the user inputs a character string “thank you” as the text T1 before conversion in the text input area 165a and presses the number key 106 corresponding to the conversion key, the conversion candidate display area 165b is displayed. A plurality of sentences (words) are displayed as conversion candidates T2 centering on Osaka dialect. The user can select an arbitrary sentence (word) from the conversion candidates T2 and execute input.

  As another example, as shown in FIG. 7, when the user inputs a character string “very hot” as the text T3 before conversion in the text input area 165a and presses the number key 106 corresponding to the conversion key, A plurality of sentences (words) are displayed in the candidate display area 165b as conversion candidates T4 centering on Osaka dialect. The user can select any one of the conversion candidates T4 and execute the input.

  Note that a predictive conversion dictionary function can be added to the character input function of the portable information terminal according to the present embodiment. FIG. 8 and FIG. 9 show the procedure of predictive conversion character input using the Osaka dialect area specific dictionary.

  For example, as shown in FIG. 8, when the user inputs the character “A” as the character string T5 before the predictive conversion in the text input area 165a, the conversion candidate display area 165b has “A” centered on Osaka dialect. A plurality of character strings that are expected to be concatenated are displayed as the prediction conversion candidate T6. The user can select any one of the prediction conversion candidates T6 and execute the input.

  As another example, as shown in FIG. 9, when the user inputs the character “shi” as the character string T7 before predictive conversion in the text input area 165a, the conversion candidate display area 165b is centered on Osaka dialect. A prediction conversion candidate T8 is displayed. The user can execute an input by selecting an arbitrary one from the prediction conversion candidates T8.

(Operation and effect of transportation fare settlement system)
According to the transportation fare settlement system according to the present embodiment described above, the transportation fare is settled in the ticket gate apparatus 2 at the time of getting off based on the information on the boarding station acquired from the ticket gate apparatus 2 when boarding, and the ticket gate apparatus. 2 is automatically stored in the region-specific dictionary storage unit 152b of the portable information terminal 1, so that the user automatically selects the region-specific dictionary to which the station, etc. to which the vehicle got off belongs, along with the settlement process when getting off the vehicle. It is possible to obtain characters and input characters using expressions specific to the area where the user gets off.

  In the present embodiment, the priority changing unit 163c can set the priority of which one of the region specific dictionary and the standard dictionary is used preferentially, and the dictionary deleting unit 163d can set a low priority dictionary. Is deleted, so even if a region-specific dictionary for character conversion is automatically obtained, a standard dictionary can be set to be used preferentially or not at the request of the user. And the like, it is possible to delete an unnecessary dictionary, and it is possible to realize character input appropriately corresponding to the needs of the user, and avoid storing unnecessary character conversion dictionaries in the portable information terminal 1. be able to.

  Furthermore, since the time elapsed since the download is measured by the timer 163e and the priority of the dictionary is lowered or deleted by the priority changing unit 163c or the dictionary deleting unit 163d, the dictionary download service is not provided. Even if the user moves due to transportation, etc., character conversion that is not intended by the user is performed by lowering or deleting the priority of the region-specific dictionary that is no longer used over time Can be prevented.
