S O M F Y CLUSES/France "CONTROL SYSTEM FOR ROLLER-BLINDS OR THE LIKE WITH SWIVEL BLADES" ABSTRACT OF THE DISCLOSURE This control system for a roller-blind or the like comprising swivel blades coupled to a master blade carry- ing at one end a stud adapted, during its downward move- ment, 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 programme of which the instruction groups are adapted to control the stud movements and the blind move- ment 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.
