<P>PROBLEM TO BE SOLVED: To adequately read/write data from/on a RF tag for a desired carried object. <P>SOLUTION: In this article carrying system 1, a carried object 14 is moved by a first carried object moving means 7 and a distance between the RF tag 16 and a reflector 11 is set to be odd-number multiples of the quarter of the wavelength of electric waves to be transmitted from an antenna 9. The phase of electric waves which pass through the RF tag 16 and arrive at the reflector 11 corresponds to the phase of electric waves which are reflected by the reflector 11 and arrive at the RF tag 16 and electric waves having these combined transmitting power are given to the RF tag 16. The phase of electric waves which are transmitted from the RF tag 16 and arrive at the reflector 11 corresponds to the phase of electric waves which are reflected by the reflector 11, pass through the RF tag 16 and arrive at the antenna 9 and electric waves having these combined transmitting power are given to the antenna 9. <P>COPYRIGHT: (C)2009,JPO&INPIT |
