Abstract

Mécanisme de déroulement de bande notamment pour magnétophone à cassette ayant un dispositif de lecture-enregistrement avec enroulement normal ou rapide en avant et en arrière. Le mécanisme utilise exclusivement des roues dentées au lieu de transmissions par friction tangentielle. Le bruit engendré par les roues dentées est éliminé en utilisant des roues dentées comportant une couronne lisse de contact associée à une partie dentées règle l'écartement d'engrènement. Application aux magnétophones à ruban, particulièrement aux magnétophones àcassette.
