  • Mechanism for retracting the pressure rollers of a tape transport when the power is off
    Patent number: 4324355
    Abstract: A tape transport has two pinch rollers, either of which presses the tape against the capstan with which that pinch roller coacts in order to advance the tape in the desired direction. When power is off, neither pinch roller should press against its capstan. A retraction mechanism includes a spring acting in a direction to withdraw or retract whichever pinch roller would otherwise bear against its capstan when the power is off. However, when the power is on, the mechanism permits the pinch rollers to function in their usual manner.
