ABSTRACT:
In a tape transport mechanism, a payout reel is supported on a shaft whereabout is wound a helical spring inertia brake fixed at a first end and free at a second end, wound such that rotation of the payout reel in response the drawing therefrom of ribbon tends to cause the helical spring inertia brake to be wound more tightly onto the shaft. A portion of the ribbon passes onto a tension arm. A projection on the tension arm engages the second free end and unwinds the helical spring inertia brake to allow rotation of the shaft opposed by a predetermined amount of torque to maintain tension in the moving ribbon. When the moving ribbon ceases to be drawn from the payout reel, the tension arm moves back for the projection to allow the helical spring inertia brake once more to grip the shaft and bring the payout reel rapidly to a halt. An energy-storing two-diameter helical friction brake is further provided on the shaft to counter-rotate the shaft on cessation of movement of the ribbon to take up any inter-reel slack and to provide ribbon-movement-opposing torque to maintain tension in the ribbon when it is moving.
