CONSTITUTION:A junction conveyer 15 is raised with an operating device raised to be connected to the final end of a carrier conveyer 1, so that the conveyer 15 is driven by a driving device 16 to locate glass plate 3 carried on the conveyer 1 onto the conveyer 15. Next, the conveyer 15 is lowered with the operating device 13 lowered to support the glass plate on it over a section between the receiving pieces 22 of the temporary setting base 20. Then the conveyer 15 is rotated by 90 deg. around the center of the longitudinal shaft, and is displaced by 90 deg. to the glass plate 3 so that they may face each other. By this, the conveyer 15 is raised to lift up the glass plate 3 and connect the conveyer 15 to the final end of the carrier conveyer 2. It is thus possible to move the glass plate 3 on the conveyer 15 to the conveyer 2 and discharge it, with the glass plate 3 carried, returning its direction by 90 deg. with regard to the direction at the time of carrying of the conveyer 1.
