    Abstract: A tape reel apparatus for recording and reproduction of motion picture film or audio tape wherein the tape is pulled off of the supply reel from the innermost convolution thereby obviating the necessity for tape rewinding after use. A pair of spaced reel plates or flanges are joined by a hub and the one plate is provided with means in the form of a ring or a roller on which the rewound tape or film may rotate with respect to the stationary reel plate. The stationary plate has a side release opening for exit of the film or tape from the innermost convolution and a guide device leads the beginning of the film or tape out of the release opening.
