| 20090317162 | PRINTER DRIVE TRAIN FOR PROVIDING AND MAINTAINING RIBBON TENSION - A drive train for a printer is disclosed that provides and maintains a desired tension in the ribbon during transfer of the ribbon between a supply spool and a take-up spool. The drive train is configured to pre-tension the ribbon proximate the driven spool prior to driving the drive roller. During operation, the drive train provides and maintains the requisite tension in the ribbon proximate the driven spool with use of a slip-overdrive assembly. Additionally, the drive train induces a drag on the spool from which ribbon is being unwound with the use of a drag-overrun assembly. | 12-24-2009 |
| 20080279603 | Rewinding reel for carbon ribbon/label carrier of label printer - A rewinding reel for rewinding a carbon ribbon or a label carrier in a label printer is provided, including a shaft, a gear, at least two sliding bases, at least two outer casing members, a resilient element, and a knob. The gear is mounted to the shaft to mate a transmission of the label printer for driving rotation of the shaft. The sliding bases are mounted to the shaft and are rotatable by the shaft. The sliding bases include movable portions that form camming projections and follower projections respectively in camming engagement with follower projections and camming faces formed on the outer casing members to radially move the outer casing members away from and toward the sliding bases for expanding and contracting the outer casing members in order to selectively loosen the carbon ribbon or the label carrier wound around the outer casing members. The knob is fixed to the movable portions and is manually depressible to move the movable portions. The resilient element provides a biasing force that sets the movable portions at a position where the outer casing members expand. | 11-13-2008 |

| 20090041526 | RIBBON CARTRIDGE FOR PRINTING - A ribbon cartridge for a printer. The ribbon cartridge including a simple mechanism that prevents an ink ribbon from being twisted or excessively drawn out in mounting thereof. Provided is a ribbon cartridge for printing, which includes: an ink ribbon; a cartridge main body which stores the ink ribbon so as to expose a part of the ink ribbon; a ribbon guide which is engaged with the exposed part of the ink ribbon so as to guide the exposed part; and a guide tape which forms a loop so as to support the ribbon guide while having one end in its longitudinal direction fixed to a first position on the ribbon guide and having the other end fixed to a second position on the ribbon guide and which is disposed so that a surface of the guide tape can face a surface of the exposed part of the ink ribbon. | 02-12-2009 |
