In step 7, first, the received count data 32 b ₂ is a predetermined number of times (e.g., 50 times) is judged whether it exceeds the performed. In this determination, the process proceeds to step 8 if it exceeds the predetermined number of times, if it does not exceed the predetermined number, the predetermined number of days from the reception date of the latest received date and time data 32 b ₁ (e.g., 60 Judgment is made as to whether or not In this determination, if it exceeds the predetermined number of days the process proceeds to step 8, if it does not exceed the predetermined number of days, a predetermined number of days from the reception date of the earliest reception date and time data 32 b ₁ (e.g., 120 Judgment is made as to whether or not If it is determined that the predetermined number of days has been exceeded, the process proceeds to step 8, and if the predetermined number of days has not been exceeded, the process also proceeds to step 8.

In step 8, when the reception frequency data 32b ₂ exceeds the predetermined frequency, only the reception frequency data 32b ₂ is displayed on the display unit 63, and the reception date in the latest reception date / time data 32b ₁ is displayed. If it exceeds the predetermined number of days from the displays on the display unit 63 and the reception date indicating a date, exceeds a predetermined number of days from the reception date of the earliest reception date and time data 32 b ₁ If the displays that is the latest and the reception date and receive count data 32 b ₂ to the display unit 63. In step 8, if the predetermined number of days is not exceeded, a message indicating that there is no problem in the usage state is displayed on the display unit 63. Thus, by displaying the determination result hierarchically, it is possible to confirm a more accurate usage state.

  When necessary based on the display on the display unit 63, the delivery person searches for the usage location of the car cart 1 based on the radio wave transmitted from the wireless IC tag 3 and confirms the usage status of the car cart 1. In addition, the usage status can be reported to the delivery destination 8.

  These steps 4 to 8 are similarly performed when the next delivery destination 8 is reached. Then, after the same operation is performed in all the delivery destinations 8, the process returns to the delivery source 7 and is repeated from step 1.

  When the wireless IC tag 3 has the determination function of Step 7 and the predetermined number of times or the predetermined number of days is exceeded, the reception status is immediately displayed on the delivery terminal 6 by transmitting the reception status to the delivery terminal 6.
