  Next, in step S38, it is determined whether or not the current position of the mobile terminal device 4 confirmed in step S37 is the same as the previous area. If it is determined in step S38 that it is not the same as the previous area (step S38; NO), the process proceeds to the next step S39. If it is determined in step S38 that the area is the same as the previous area (step S38; YES), the process returns to step S33 via step S36, and thereafter, the processes in steps S33 to S38 until NO is determined in step S38. Is repeatedly executed.

  In step S39, it is determined whether there is untransmitted data that has not been transmitted to the headquarter server 2 among the delivery completion data stored in the predetermined storage area of the RAM 46. If it is determined in step S39 that there is untransmitted data (step S39; YES), the process proceeds to the next step S40. If it is determined in step S39 that there is no untransmitted data (step S39; NO), the process proceeds to step S41 without executing step S40.

  Next, in step S40, the delivery completion data stored in the predetermined storage area of the RAM 46 is transmitted to the headquarter server 2 by the WAN communication unit 48.

  In step S41, the position information output from the GPS unit 47 is acquired, and the acquired position information is transmitted to the headquarter server 2 by the WAN communication unit 48. When this step S41 is executed, the delivery completion data transmission process of FIG. 7 ends.

  As described above, in the delivery completion data transmission processing of the fourth embodiment shown in FIG. 7, the barcode data printed on the slip is obtained by scanning the slip of the package that has been delivered to the delivery destination by the scanner unit 44. Each time reading is performed, delivery completion data is generated based on the barcode data, and the generated delivery completion data is stored and stored in the RAM 46, and the mobile terminal device 4 is moved according to the position information output from the GPS unit 47. When the distance is calculated and the mobile terminal device 4 moves within a predetermined time, refer to the area classification map database shown in FIG. 8 based on the position information output from the GPS unit 47. Then, it is determined which area the current position of the mobile terminal device 4 is, it is determined that it is not the same as the previous area, and it is determined that there is untransmitted data. If, it transmits a delivery completion data stored in the RAM46 through WAN communication unit 48 to the headquarters server 2.

  As a result, the mobile terminal device 4 does not transmit the delivery completion data to the headquarter server 2 every time the slip is scanned, but accumulates a plurality of generated delivery completion data so that the mobile terminal device 4 And the accumulated delivery completion data is transmitted to the headquarter server 2 when it is determined that the current position of the mobile terminal device 4 is not the same as the previous area and there is untransmitted data. By transmitting the delivery completion data collectively for each determined area, the number of transmissions can be reduced to the minimum, so that the communication cost can be reduced and the battery life of the mobile terminal device 4 can be extended.

  As described above, the mobile terminal device 4 of the present embodiment includes the scanner unit 44 that scans a slip and reads barcode data printed on the slip, the RAM 46, the GPS unit 47 that outputs position information, and WAN communication. Each time the package slip scanned by the scanner unit 44 is generated and accumulated in the RAM 46 and output from the GPS unit 47. The movement / stop of the mobile terminal device 4 is determined according to the position information. If it is determined that the mobile terminal device 4 is moving, the delivery completion data stored in the RAM 46 is transmitted to the headquarters server by the WAN communication unit 48. Since it comprised so, communication cost can be reduced and the battery life of a terminal can be lengthened.
