Abstract

PURPOSE:To prevent the surface of a plate-shaped body from being impaired by providing both pinchedly holding means and a loading means so as to be relatively movable at least in the up-and-down direction or in the up-and-down, front-and-rear, and right-and-left directions. CONSTITUTION:By operating air cylinders 5, pinchedly holding members 1, 1 are closed to pinch both opposite end edge parts of a plate-shaped body (a) by the end parts thereof. Then, by lifting the members 1, 1 in that condition up-wards in the Z direction, only the uppermost one sheet of the plate-shaped bodies is lifted up. Thereafter, the pinchedly holding members 1, 1 are moved horizontally in the Y direction so as to be positioned right above a prescribed transfer part such as a belt conveyor or a prescribed position, and in that condition, the pinchedly holding members 1, 1 are lowered in the Z direction towards the prescribed position, and then the members 1, 1 are opened to supply the plate-shaped body onto a prescribed position such as a belt conveyor. Then, the members 1, 1 are again lifted upwards in the Z direction in the opened condition, and are returned to the position right above the plate-shaped bodies (a) on a table 8 as before.
