The cassette on the turntable is turned selectively through an angle of 180.degree. and wafers are lifted by the link mechanism all at a time and selectively held by the opening/closing chuck mechanism. The wafers thus held are conveyed to a location of a boat where they are loaded onto the boat in a face-to-face relation.
