The present invention discloses a separate waver handling device for elevating and rotating wafers accommodated in a cassette for visual inspection, one by one. The separate waver handling device comprises a bed having a hole at a position where the cassette is positioned; and a wafer handling unit for elevating and rotating the wafers in the cassette through the hole one by one. The wafer handling unit comprises a wafer rotation part for rotating the wafers one by one and a twinaxis transmission part for moving the wafer rotation part in a vertical direction and a horizontal direction, which are the same as the directions in which the wafers are arranged, for selecting a single wafer by the horizontal directional movement of the wafer rotation part and elevating the selected single wafer by the vertical directional movement of the wafer rotation part.
