Remote- controlled light receiving structure of electric roll screen for blind

A remote-controlled light receiving structure of an electric roll screen for blind which is structured so that a take-up pipe placed along an upper edge of a window of a building is rotatably supported at both ends there of by side brackets, while an upper end of the screen having a weight bar attached to a lower end there of, is fixed to the take-up pipe, so that the take-up pipe is rotated in forward and reverse directions by a motor to wind up and down the screen,

• wherein a bracket cover is mounted on an outer surface of one of the side brackets and has, at a lower end thereof, a transparent, circular-arc-shaped, light receiving surface separate from or part of the bracket cover, and a light receiving unit to receive a pulsed optical signal applied from a remote controller through the light receiving surface is mounted through a light receiving unit holder, and wherein the light receiving unit holder is mounted on the bracket cover so that is can pivot about a center point of the circular-arc-shaped light receiving surface, and the light receiving unit is arranged so that it can be rotated together with the light receiving unit holder so that is can be switched to two different orientations where the light receiving directions are symmetric with respect to a vertically downward direction and the phases are different from each other.
