Abstract

A tape drive mechanism for magnetic tape apparatus for tapes housed in cassettes has a pressure roller (29) at one end of a press-on lever (35) which is pivotally held on a drive shaft bearing (31) of a drive shaft (30) so that it can be inclined in a vertical plane. Another end of the press-on lever (35) has the guide cavity (37) in which a grade element (38) is held. The guide element is affixed at the end of a bascule lever (40) which is pivoted also on the supporting bearing (31) of the drive shaft (30). The bascule lever (40) is controlled by the progress of a tape threading operation of a tape loading device, the control being in the axial direction of the drive shaft (30).
