ABSTRACT:
A side access opening is provided in a side wall of a continuous loop tape cartridge which is normally driven in a forward direction by the capstan of a tape player through an access opening in its front wall to remove tape from a central hub at the inner convolution thereof and to return it to the hub at the outer convolution. A cooperating side drive mechanism is provided in the tape player housing adjacent the side access opening in the cartridge. The tape is driven in a reverse direction through the cartridge by the side drive mechanism of the player through the side access opening to remove tape from the hub at the outer convolution thereof and to return it to the hub at the inner convolution by being coupled to a vertical peripheral wall portion of the cartridge hub at a point spaced a predetermined distance from the axis of rotation of the hub. The coupling relation is effected either directly through the outer convolution of tape or directly to the rim of the hub or simultaneously through both means. Further alternative embodiments are provided for coupling the drive means of the player to the hub through one or more idler wheels in the cartridge. Several embodiments of a side drive are disclosed. Actuating means selectively couple the side drive mchanism to the hub. Means are also provided for using the side drive mechanism to drive the tape in a fast forward direction through the cartridge. In reverse winding, the tape is guided onto the peripheral wall portion of the hub by being applied against an adjacent curved flange portion of the hub. A pivotable lever momentarily moves the cartridge outwardly in the player cartridge receiving cavity to disengage the capstan from its coupled relation to the tape through the front access opening whenever the reverse or fast forward modes of operation are selected. In one embodiment means are provided for reversing the direction of rotation of the player drive as appropriate to drive the tape forwardly or in reverse.
