Abstract

Dispositif de commande de levage, pivotement et abaissement du bras lecteur d'un tourne-disques. L'élément de commande est un disque qui présente une encoche pour le doigt avec un senseur à effleurement, ce disque pouvant tourner autour de son axe dans les deux sens et provoquant pour chacune de ses rotations un nouveau réglage de la tension d'alimentation d'un contact électronique de déclenchement du mouvement du bras. Application à l'industrie de la haute fidélité.Device for lifting, pivoting and lowering the drive arm of a turntable. The control element is a disc which has a notch for the finger with a touch sensor, this disc being able to rotate around its axis in both directions and causing a new adjustment of the supply voltage for each of its rotations. 'an electronic contact triggering the movement of the arm. Application to the high fidelity industry.
