A take-up projection on the take-up housing and the main wall jointly define a take-up window therebetween through which donor ribbon passes into the take-up area. The take-up projection includes at least one tensioning feature so as to pre-load the take-up projection such that the take-up projection is inhibited from warping toward towards the main wall.

  • Patent number: 7722268
    Abstract: A tape drive for use in for example a transfer printing apparatus to drive a printer ribbon. The printer ribbon is mounted on two spools each of which is driven by a respective stepper motor. A controller controls the energization of the motor such that the ribbon is transported in at least one direction between spools mounted on the spool support. The controller is operative to energize both motors to drive the spools of ribbon in the direction of ribbon transport to achieve push-pull operations. Ribbon tension is monitored to enable accurate control of ribbon supply and ribbon take-up, the ribbon tension being monitored, for example, by monitoring power supply to the two stepper motors.

  • Patent number: 7695204
    Abstract: A wide format printer having an alternative print zone arrangement is provided. The printer comprises a printhead having a corresponding print zone, the print zone being defined by a plane adjacent the printhead, and a feed mechanism for continuously feeding a web of print media through the print zone. The printer is characterized in that the web is unsupported in the print zone, which obviates the need for a platen and advantageously maintains a constant distance between the printhead and the web.

    Abstract: The present invention provides a cartridge providing ribbon tension. The cartridge includes a cartridge housing having walls. A first spool and a second spool are contained in at least in part in the cartridge and have a ribbon extending therebetween. The first spool and the second spool extend between a pair of ends with at least one of the pair of ends having a driving portion. At least one resistance-applying part extends around a portion of each of the first spool and the second spool. The first spool and the second spool have a loaded and an unloaded position. In the loaded position, at least one of the resistance applying part is disengaged from the walls of the cartridge. In the unloaded position, at least one resistance-applying part engages the walls of the cartridge.

  • Patent number: 7467902
    Abstract: A rotational torque adjustment apparatus is used to adjust the rotational torque of a rotational member secured to a rotational shaft for integrally rotating with the rotational shaft. The rotational torque adjustment apparatus includes a friction member for contacting with the rotational member to apply a frictional load to the rotational member, a brake member for holding the frictional member thereon, a pressing member for pressing the friction member held on the brake member with a predetermined pressure against the rotational member, and a guide section for holding the brake member for movement thereon. The brake member is moved in a radial direction of the rotational member along the guide section to vary the rotational torque of the rotational member.

  • Patent number: 7448813
    Abstract: Incorporates means for maintaining a constant tension in the printing ribbon (3) consisting of a loading drum (9-9') placed after the thermal print head (1) that attracts the ribbon to define a loop, thereby maintaining a constant tension throughout the printing stage to ensure the quality of this operation. The printing method consists of attracting or suctioning the printing ribbon (1) against the loading drum (9-9'), using an electrostatic system that involves creating an electric field between conductors (10) placed on the loading drum (9), or a pneumatic system that involves attracting the ribbon (1) by Venturi tubes (17) located inside the loading drum (9').

  • Patent number: 7441970
    Abstract: Identity document processing equipment with a mechanism designed to maintain tension in a ribbon used in a processing operation in the processing equipment. The tension maintaining mechanism is separate from the supply roll and the take-up roll for the ribbon, eliminating the need for clutches or brakes attached to the supply or take-up rolls to achieve tensioning. Since the tension maintaining mechanism is separate from the supply roll and the take-up roll, the inertia of the supply roll or the take-up roll does not affect the tension on the ribbon during use of the processing equipment.
