ABSTRACT:
This control system for a roller-blind or the like comprising swivel blades coupled to a master blade carrying at one end a stud adapted, during its downward movement, to travel in a slide groove disposed behind a rocker and, during its upward movement, to engage both the slide groove, and the rocker, this control system comprises a microcomputer having stored in its non-volatile memory a control program of which the instruction groups are adapted to control the stud movements and the blind movement in relation to four predetermined stop points with respect to the rocker. The movements of the blind and of its stud are controlled as a function of the relative state of two switches of an auxiliary device rotatably coupled to the winding tube of the blind, as a function of the 1 or 0 state of a first register which assumes state 1 only when the stud is inside the rocker and also as a function of the 1 or 0 state of a second register which assumes state 1 only when the stud has overstepped at least once the first upper point after the last switching-on of the system, the first and second registers being incorporated in the non-volatile memory of the microcomputer.
