Abstract

L'invention concerne le matériel d'enregistrement. Elle a pour objet un appareil d'enregistrement à bande qui comporte un mécanisme transporteur de bande comportant un dispositif à axe d'alimentation 26 muni d'un frein magnétique 66 ou 110 ainsi qu'un dispositif à axe de renvidage 28 muni d'un embrayage magnétique 82. La bande passe de la bobine débitrice à la bobine réceptrice, tandis que des forces magnétiques de freinage exercées par le frein magnétique et des forces magnétiques variables d'accouplement exercées par l'embrayage magnétique entretiennent une tension sensiblement constante dans la bande Une rondelle d'espacement, non magnétique, est prévue dans l'entrefer du frein 78 ou 78' et/ou de l'embrayage 102 pour améliorer le fonctionnement. Cet enregistreur est préféré pour l'enregistrement codé des consommations d'électricité.
