PURPOSE:To enable a sheet-shaped body, such as a glass plate to be placed on the specified position of a hot plate without impairing said body, by providing said hot plate with a plurality of gas withdrawing holes. CONSTITUTION:Hot plate 3 is provided with a plurality of small holes 5. When glass plate 2 is placed with an unfixing tool, such as unshown blades, the air between plate 2 and plate 3 goes out of holes 5 rapidly, thus permitting the compressed air generated instantaneously between plates 2, 3 not to float plate 2 in such a pressure, and plate 2 to come down exactly on the position intended to place. |
