ABSTRACT:
A roll screen apparatus improved in operation and manufacturing, wherein the winding up and down of the roll screen are effected in such a manner so that the rotation of the pulley, by the pulling down of the operation cord, is transmitted to the screen winding pipe, and wherein the stop of the screen is effected by disengaging the transmission from the screen winding pipe to the pulley. The improved apparatus is characterized by providing a clutch device and a disengagement device. The clutch device is only transmissive of the rotation of the pulley to the screen winding pipe, and the disengagement device disconnects the engagement between the pulley and the screen winding pipe and maintains such disconnected condition.
