A cleaning device of a recording and/or reproduction apparatus using a magnetic tape as a recording medium and including a rotary head device having a rotary drum provided with magnetic heads. This cleaning device includes a cleaning member which comes into contact with the magnetic heads of the rotary head device and an operation mechanism which brings the cleaning member into contact with the magnetic heads while the rotary head device is rotating. The operation mechanism brings the cleaning member into contact with the magnetic heads while the rotary drum is rotating before the magnetic tape is loaded to the rotary head device by a tape loading mechanism, whereas it separates the cleaning member from the magnetic heads when the magnetic tape is loaded by the tape loading mechanism to the rotary head device. The magnetic head is cleaned whenever the magnetic tape is loaded.

Cette invention concerne un dispositif de nettoyage pour appareil d'enregistrement et/ou de reproduction faisant appel à une cassette magnétique comme support d'enregistrement et comportant un dispositif à têtes rotatif, lequel possède un tambour rotatif équipé de têtes magnétiques. Ce dispositif de nettoyage comprend un élément de nettoyage entrant en contact avec les têtes magnétiques du dispositif à têtes rotatif, ainsi qu'un mécanisme d'actionnement amenant l'élément de nettoyage en contact avec lesdites têtes magnétiques durant la rotation dudit dispositif à têtes rotatif. Le mécanisme d'actionnement amène l'élément de nettoyage en contact avec les têtes magnétiques pendant la rotation du tambour rotatif avant le chargement de la cassette magnétique dans le dispositif à têtes rotatif par un mécanisme de chargement. Le mécanisme d'actionnement sépare l'élément de nettoyage des têtes magnétiques lorsque la cassette magnétique est chargée dans le dispositif à têtes rotatif par le mécanisme de chargement de cassette. La tête magnétique est ainsi nettoyée quel que soit le moment où la cassette magnétique est chargée.
