Abstract
An ink ribbon cartridge has first and second tubes ( ) for holding an ink ribbon. The tubes have slots formed in each end. Spindles ( ) are attached at the ends of the tubes. The spindles have a disk portion and an end which is received by tube slots. One of the spindles has a cantilevered member ( ) which engages a slot of a tube and allows rotation of the tube in only one direction. The cantilevered member has an end having a radial edge ( ) and a ramp ( ) adjacent the straight side. Rotation of the spindle in one direction abuts the radial edge against a wall of the slot thus providing a positive drive and allowing rotation of the tube with the spindle. Rotation of the spindle in a second direction opposite to the first direction causes the ramp side to contact and slide along a wall of the slot, thus deflecting the cantilevered member inward toward the center of the spindle.
