An independently driven multiple-shaft roll screen includes at least one sectional roll screen horizontally installed to one side of a first sectional roll screen in series, and a multiple-shaft independently driving controller installed to the other end of the first sectional roll screen and including chain wheels engaged with ball chains such that a corresponding ball chain is inde pendently lifted and lowered by a user at a position and driving shaft pipes coupled with the chain wheels, wherein more than two driving shaft pipes are inserted into a driving shaft pipe of a first sectional roll screen in turn and are coupled with corresponding roll driving parts of respective sectional roll screens such that driving force, generated by the multiple-shaft independently driving controller due to lifting and lowering of a corresponding ball chain, is independently transmitted to a corresponding roll screen through a driving shaft pipe of the driving part of the respective roll screen. |
