ABSTRACT:
A magnetic-tape cassette machine of the type including a horizontally extending tape drive shaft and a loading platform designed to hold the cassette upright during tape transport. To prevent the horizontally extending tape drive shaft from shifting axially during tape transport, one end of the shaft is supported against a first axial bearing secured to the machine housing and the other end is supported by an axial bearing secured to the loading platform. Alternatively, a single axial bearing is used limiting axial shifting of the tape drive shaft in one direction, and a permanent-magnet arrangement pulls the tape drive shaft in the same direction to prevent the shaft from shifting axially in the opposite second direction.
