<p>A transport system is configured of a mobile unit (40, 40') attached with a non-contact type IC card (10a, 10a') absent of a power source, receiving and rectifying a radio wave to obtain power to operate; an interrogator body 20 having an antenna unit (21b) to transmit the radio wave and data, and transferring data with the IC card (10a); and a travel control device 30 controlling a travel direction of a mobile unit according to a control signal from interrogator body 20. The antenna unit (21b) is attached to a react unit (21a) that reacts when in contact with the mobile unit (40). The distance between the IC card attached to the mobile unit and the antenna unit of the interrogator can be reduced significantly than that of the conventional case irrelevant to the shape and size of the mobile unit. By supplying from the antenna unit (21b) the weakest radio wave required for the IC card that transfers data, a transport system can be provided that can transfer data efficiently and without almost no interference. <IMAGE></p> |
