Abstract: A traction device has an origin cylinder (1) of heat-sensitive ink ribbon (2), a rewinding cylinder (5), traction means and a marking header. The device prevents unused segments of ribbon being left between markings. The device has a moving support (6) guiding the ribbon (2) along an additional path (16), braking means (10, 11, 12, 14) for the origin cylinder (1). When the ribbon (2) is tractioned and the origin cylinder is braked, the support (6) is forced to move against the action of an elastic element (13), reducing the additional path (16). Thus, after a marking (a-b) the ribbon and the support (6) move back so that the next marking (b-d) is made immediately after the first marking (a-b). The braking means, after one or more markings, are released, unrolling a length of ribbon (2) from the origin cylinder, then braking again, with the process repeated.

Abstract: An ink ribbon cartridge has first and second tubes (130, 132) for holding an ink ribbon. The tubes have slots formed in each end. Spindles (140, 142, 162, 164) 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 (196) 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 (200) and a ramp (202) 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.

Abstract: Apparatus for adjusting the spacing in a printer between a printhead and the travel path for print media which moves through the printer.
