Abstract
A reel table assembly for driving a tape reel which has a center hole and a plurality of equally spaced inwardly extending radial teeth formed circumferentially thereof comprises a reel table formed centrally with a reel shaft for carrying thereon the tape reel with the center hole, and a plurality of equally spaced drive pawls which are provided circumferentially in the reel shaft and project radially outwardly of the reel shaft under a resilient force for mesh engagement with the radial teeth of the tape reel. The drive pawls are movable radially inwardly of the reel shaft when the tape reel is carried on the reel table with the radial teeth being in radial abutment on the drive pawls. A friction member is provided on the reel table for direct contact with the tape reel to provide a high degree of friction between the reel table and the tape reel carried on the reel table. The reel table also comprises a low-friction means provided on the reel table for direct contact with the tape reel to maintain the tape reel lifted off the friction member only when the tape reel is carried on the reel table with the radial teeth being in radial abutment with the drive pawls.
