A pair of reel spindles are mounted on the same axis normal to a tape deck, the inboard spindle adjacent the tape deck being journalled for independent rotation upon the exterior of a bearing means extending from the deck, and the outboard spindle remote from the deck being mounted on a shaft extending interiorally of the bearing means for independent rotation with respect to the outboard spindle. The inboard spindle includes a turntable flange and key portions extending into keyways in the inboard reel. The outboard spindle has radially extending key portions mating with the keyways of the inboard reel, to permit passage of the inboard reel freely to and from the inboard spindle. The outboard reel is provided with truncated keyways that mate with the outboard spindle keys but prevent passage of the outboard reel inboardly to the region of the inboard spindle.
