As an interrupt start button is depressed while control, under which product wafers Wp and dummy wafers Wd are transferred in an order defined in a normal transfer pattern, is repeatedly executed, a decision is made based upon wafer transfer history as to whether or not the most recent transfer pattern cycle has ended. If the cycle is determined to have ended, the operation immediately proceeds to the subsequent cycle to transfer interrupt wafers Wf and Wd in an order defined in the interrupt transfer pattern achieved by replacing Wp in the normal transfer pattern with Wf, whereas if the cycle is determined to be incomplete, the wafer transfer based upon the normal transfer pattern is carried on until the cycle ends and then the operation proceeds to the next cycle to transfer Wf and Wd in the order defined in the interrupt transfer pattern.
