Abstract

Procédé de fabrication d'un générateur de signaux pour un dispositif d'entraînement de tourne-disque ou de bande magnétique comprenant un moteur de commande et respectivement un plateau tournant ou un arbre à cabestan et dans lequel le génerateur de signaux est monté sur une surface porteuse symétrique en rotation et produit une suite d'impulsions dont la fréquence est proportionnelle à la vitesse de rotation du plateau ou de l'arbre à cabestan, un récepteur pour la suite d'impulsions étant associé au générateur de signaux. Le générateur de signaux 36; 70 est fixé sur la surface porteuse 38; 69 sans veiller à un centrage précis et est ensuite muni simultanément de tous les signaux. L'invention est applicable à des tourne-disques et magnétophones.A method of manufacturing a signal generator for a record player or magnetic tape drive device comprising a drive motor and a turntable or a capstan shaft, respectively, and wherein the signal generator is mounted on a surface carrier symmetrical in rotation and produces a series of pulses whose frequency is proportional to the speed of rotation of the plate or of the capstan shaft, a receiver for the series of pulses being associated with the signal generator. The signal generator 36; 70 is fixed on the carrier surface 38; 69 without ensuring precise centering and is then provided simultaneously with all signals. The invention is applicable to record players and tape recorders.
