APPARATUS FOR SYNCHRONIZING THE SLATS OF MOTOR DRIVEN WITHOUT BLINDS. ABSTRACT OF THE DISCLOSURE This invention relates to a circuit arrangement and the associated mechanism for slaving the angles of rotation of the slats of a plurality of centrally controlled sun or window blinds. The driving motor of each blind is provided with current via a corresponding operational amplifier and related circuit. The motor operates the slats to achieve balance between an input control voltage and a voltage depending on the angular position of the slats. An automatic version in which the control voltage is generated by a photoelectric sensor and several circuit variations are shown.
