a transfer system includes : a first shelf blocking an original transfer path from a transfer position at which the transporting vehicle transfers the transported object to the port and which transfers the transported object with the transporting vehicle ; a second shelf that puts the transported object ; a displacing device which reciprocates the transported object with respect to the first shelf and the port in a first direction , toward and away from the processing apparatus , and reciprocates the transported object at a first direction position , away in the first direction by the transported object from the first shelf and the port , in a second direction crossing the first direction ; and a communicating device receiving a first system signal indicating a transfer request from the transporting vehicle , which transmits a second system signal indicating a transfer permission to the transporting vehicle , which transmits the first system signal to the processing apparatus .
