Abstract
PURPOSE:To enable a stable orientation treatment by using a rubbing cloth which is attachable and detachable to and from a rotary drum, disposing the contact direction of a liquid crystal substrate and rubbing cloth to the directions where both face each other and providing a destaticizing means and suction means respectively to the rubbing cloth, thereby executing the orientation treatment. CONSTITUTION:The substrate 1 held to a vacuum chuck base 2 actuates a microswitch 21 when the substrate is inverted. The drum 7 is already held fixed with the rubbing cloth 8 at this time and is kept rotated by a motor 19 in an arrow 22 direction; the destaticizing device 19 and the suction in a suction port 20 are simultaneously operated. The dust and cloth dust on the rubbing cloth 8 are cleaned by the suction port 20. The vacuum chuck base 2 is held stopped after the operation of the microswitch 21. The vacuum chuck base 2 moves a shaft 3 in an arrow 4 direction by a motor when a cam 17 actuates the microswitch 18 by rotation of the drum 7. The contact of the sewed part of the rubbing cloth 8 with the substrate 1 is thereby obviated and the stable orientation treatment is executed by the rubbing cloth 8 except the sewed part thereof.
