ABSTRACT:
A unitary hub for receiving and securing a reel of recording tape is disclosed. The hub has a housing having a plurality of openings disposed between the base and the top of the housing. A corresponding plurality of resilient detents, disposed internally to the housing, is urged partially through the openings therein. The detents retract into the housing when a reel of recording tape is moved over the detents toward the base of the hub, and thereafter protrude through the openings to apply pinching forces against the reel for holding the reel in place.
