ABSTRACT:
A dual reel drive system for a video recorder/reproducer comprising first and second identical reel drive assemblies, each of the assemblies including a drive shaft; a motor connected to the drive shaft; a first clamping ring connected to one end of the drive shaft; a push rod mounted coaxially with the drive shaft; a second clamping ring connected to one end of the push rod, adjacent the first clamping ring; an expandable gripping ring mounted between the first and second clamping rings, the gripping ring and the second clamping ring being adapted to extend into a reel for engaging same, movement of the first and second clamping rings towards each other longitudinally compressing and laterally expanding the gripping ring into engagement with a reel mounted thereon; a spring connected between the other ends of the drive shaft and the push rod for applying a force therebetween to maintain the gripping ring in the expanded condition; and an actuating shaft and a cam member for selectably separating the clamping rings to permit relaxation of the gripping ring and release of the reels. In a dual drive system, the actuating cams are mounted on a single actuating shaft for simultaneous operation of the two drive assemblies, the cams being located so as to rotate the push rods as the gripping rings are expanded in directions to increase the tension in the tape extending between the reels to take up any slack existing therein.
