Abstract
Mouvement de la bande dans un magnétophone à bande. Dispositif à galet presseur pour, dans les magnétophones à cassette, pousser la bande magnétique contre le cabestan d'entraînement, dispositif caractérisé en ce que le galet presseur comporte une cavité axiale dont le diamètre est nettement plus grand que celui de la broche, ou pivot, qui le supporte, sauf dans une région de dimension axiale limitée dans laquelle ladite cavité et ladite broche sont généralement en appui l'une contre l'autre pour pouvoir tourner, des moyens de butée étant prévus pour permettre audit galet de se déplacer angulairement mais en limitant ses mouvements axiaux par rapport à ladite broche, l'agencement des éléments étant tel que ledit galet puisse se deplacer angulairement par rapport à ladite broche et pouvoir ainsi tourner autour d'un axe de rotation parallèle à l'axe de rotation dudit cabestan. Application : magnétophones à cassette.Movement of the tape in a tape recorder. Pressure roller device for, in cassette tape recorders, pushing the magnetic tape against the driving capstan, device characterized in that the pressure roller has an axial cavity whose diameter is significantly greater than that of the spindle, or pivot , which supports it, except in a region of limited axial dimension in which said cavity and said spindle generally bear against each other in order to be able to rotate, stop means being provided to allow said roller to move angularly but by limiting its axial movements with respect to said spindle, the arrangement of the elements being such that said roller can move angularly with respect to said spindle and thus be able to rotate about an axis of rotation parallel to the axis of rotation of said capstan . Application: cassette tape recorders.
