Abstract
Disclosed is a reel hub latch assembly used in magnetic tape recording/reproducing apparatus. The disclosed reel latch assembly accurately locates a reel on a hub and prevents slippage between the hub and reel when the reel is rotated to transport tape onto and off of the reel. The reel mounting hub has an annular groove containing an annular, U-shaped radial spring at the bottom of the groove. The radial spring has a plurality of circumferentially spaced fingers. An annular garter spring is located in the groove overlying the circumferentially spaced fingers of the radial spring. A magnetic tape reel, mounted on the hub, has a conical inner wall which is engaged by the garter spring. Preferably, the engaging portions of the spring are shaped to conform to the shape of the conical wall to reduce stresses on the reel.
