Variable roller blind structure

A variable roller blind structure includes a roller blind made up of more than one blind bodies that are respectively attached to the underside of a rotatable roller shaft and a stable roller shaft juxtaposed at an interval and mounted at the inner side of an upper beam. The blind body has a plurality of light-passable areas alternatively arranged with a plurality of black-out areas disposed at the surface thereon, and a winding unit is mutually engaged with the rotatable roller shaft to be controlled by an operating member that is pulled either clockwise or counterclockwise to actuate the movement of the rotatable roller shaft accordingly so as to control the rolling or unrolling operation of the blind body thereby. Via the structure above, the blind bodies of the roller blind can have it both ways with partial transparency and partial sheltering effect for privacy purpose. Besides, when the rotatable roller shaft is wound by the operating member to actuate the rolling movement the blind body till the light-passable areas of the blind body rolled upwards are correspondingly juxtaposed with the black-out areas of the other blind body, the light-passable areas of each blind body thereof can be precisely sheltered by the black-out areas of the other respectively, completely blocking out all light outdoors so as to achieve a total sheltering effect thereof. Thus, the roller blind thereof is capable of being variably operated to cater to the needs of users and is efficiently boosted in its functions thereof.
