To provide a transport means and a loading confirming system capable of quickly informing loading-unloading to a driver, a controller, or the like when a loading object is loaded and unloaded when the transport means is not in a normal loading-unloading mode.
This loading confirming system is composed of a first antenna 2a and a second antenna 2b for transmitting and receiving a radio wave with a noncontact IC tag 6 installed on the loading object (a vehicle 1), a reader-writer 3 for storing a received signal in the antennas, the transport means (a carrier car 7) composed of a communication device 4 capable of communicating reading data in the reader-writer to an external part, and a confirming means 5 for confirming a loading state of the loading object and a loading and unloading state of the loading object on the basis of communication information from the communication device 4. Here, the moving direction of the loading object is performed with a difference between a received radio wave of maximum strength received by the two antennas and the time when receiving the received radio wave.
