A motorized tape reel is carried on a mandrel shaft extending between a pair of brackets. At the first bracket, the mandrel shaft joins with a swivel ring which permits rotation and axial sliding of the mandrel shaft. The swivel ring swivels on vertical pins in order to swing the mandrel shaft out of its position between the brackets. A second shaft, journalled for rotation within the second bracket, has a power drive connection at its outer end and a separable coupling at its inner end for driving the mandrel shaft. A biasing spring at the first bracket urges the mandrel shaft towards the second bracket, thereby closing the coupling. To change tape reels, manual force is applied to the mandrel shaft to overcome the biasing spring and separate the coupling. The mandrel shaft is then swung out from between the brackets, and the old tape reel is removed. The reverse steps are followed to install a new tape reel.
