Abstract
A device including a tube for winding and unwinding a screen which is controlled in rotation by a gear motor and which is supported on a fixed head and wherein a rotational part mounted within the tube is kinematically linked to rotate with the tube with the part including elements that are used to reflect a position of the rotational part and which elements are detected by senors that are connected to an electronic processing unit. A tightly sealed partition secured to the head is further provided to define, on one side, a first compartment for receiving at least the rotational part and, on the other side, a second compartment for receiving at least the electronic processing unit.
