Abstract

<P>Mouvement de la bande dans un magnétophone à bande. <P> the tape movement in a tape recorder. 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. Device for the pressure roller in the tape cassette, push the magnetic tape against the capstan drive, device characterized in that the pressure roller has an axial cavity having a diameter substantially larger than that of the spindle or pivot which supports it, except in a limited axial dimension of region wherein said cavity and said pin are generally in abutment against each other for rotation, stop means being provided to enable said roller to move angularly but by limiting its axial movements relative to said spindle, the arrangement of the elements being such that said roller can move angularly with respect to said spindle and thus rotatable about an axis of rotation parallel to the axis of rotation of said capstan . </P><P>Application : magnétophones à cassette.</P> </ P> <P> Application: cassette recorders </ P>.
