  • Patent number: 9011029
    Abstract: The ribbon winding unit is equipped with a first moving gear, a second moving gear, a first intermediate gear, a tumbler gear, and a winding member. The first intermediate gear engages with the first moving gear when the first moving gear and the second moving gear move in a given direction, and disengages from the first moving gear when the first moving gear and the second moving gear move in an opposite direction. The tumbler gear engages with the first intermediate gear, engages with the second moving gear when the first moving gear and the second moving gear move in the opposite direction, and disengages from the second moving gear when the first moving gear and the second moving gear move in the given direction.

    Abstract: A system is provided for movably supporting an ink film in a printer. The system has cylindrical supply and take-up cores for supporting and taking up the film during printing operations. The cores may be made of molded plastic resin. The ends of the cores are sized to selectively fit within a frame in such a way as to provide stable operation, including where applicable, while a frame cover is closed. In a preferred embodiment, the diameters of the first and second ends of the supply and take-up cores are essentially the same, and the diameters of the second and first ends of the respective cores are essentially the same. A molded cylindrical brake portion frictionally contacts the teeth of a brake gear to provide the desired film tension with improved handling and with reduced likelihood of jamming.

  • Patent number: 6905268
    Abstract: An ink ribbon cartridge has a take-up spool (130) with an opening having a plurality of drive surfaces (200) and slip surfaces (202). The take up spool is preferably of a one-piece construction. A first spindle with a cantilever member (196) and a tab (198) extending therefrom is mounted on the take-up spool. When the drive surface engages a tab of the spindle, rotation of the spindle rotates the take-up spool. When one of the slip surfaces engages the tab of the spindle, the spindle rotates relative to the take-up spool.

  • Patent number: 6422770
    Abstract: An inked ribbon assembly for use with a printing apparatus such as a thermal facsimile machine includes a generally cylindrical supply spool, a generally cylindrical take-up spool, and a sheet-like inked ribbon extending therebetween, with the inked ribbon rolled upon the supply spool and connected to the take-up spool for advancement through the printing apparatus to the take-up spool. The spools of the inked ribbon assembly are rotatably supported in the printing apparatus by support spindles, which effect driven rotation of the supply and take-up spools. The support spindles each include one or more drive lugs which engage the spools of the ribbon assembly for effecting advancement of the inked ribbon.

  • Patent number: 6145769
    Abstract: A thin ribbon cassette (16) is a set on a tape winding device and its vertical-direction position is fixed by a position restricting member (18) provided on a back of a cover and for an apparatus body. When the ribbon cassette (16) is thin in correspondence to a narrow width of an ink ribbon (15), a quantity of lowerig a ribbon winding top (5) engaged with a reel (16-1) of the cassette (16) is small. The biasing force of a clutch spring (7) which is compressed depending on the quantity of lowering of the ribbon winding top (5) is small, the force of a winding driver gear (6) which presses a clutch plate (4-1) through a felt member (12) is small, the frictional force of the felt member (12) is small, and the torque of the rotational shaft (4) is small. This torque is just suitable for winding a long and narrow ink ribbon having a corresponding small tensile strength.

  • Patent number: 6039477
    Abstract: It is an object of the present invention to provide an ink ribbon take-up mechanism whereby a core and a pinch roller both disposed in an ink ribbon cassette are prevented from being tilted or wobbled under the tension of an ink ribbon housed within the ink ribbon cassette while a carriage is driven (during printing), thereby permitting the core and the pinch roller to be rotated in a more stable manner. The ink ribbon take-up mechanism comprises a support shaft projected from a ribbon cassette loading surface of a carriage to a ribbon cassette loading side and adapted to be inserted into an engaging portion formed on the ribbon cassette side to support the ribbon cassette, and a drive transfer member disposed rotatably on an outer periphery side of the support shaft and adapted to be engaged with the engaging portion formed on the ribbon cassette side to transmit a rotative driving force of a motor to the engaging portion.

  • Patent number: 5959652
    Abstract: A thermal ink ribbon cassette for holding an inked ribbon of indefinite length for use in a thermal transfer printing mechanism holds a spool of fresh ink ribbon which passes out of the cassette and across a thermal printing head, and then back into the cassette. The features of construction and arrangement of the cassette are such that the length of the portion of the normal feed path of envelopes through the mailing machine in which the ink ribbon and the envelopes travel coextensively is reduced to an absolute minimum to avoid unnecessary contact after printing take place. A slanted wall is provided for ensuring that the envelopes remain in their normal path of travel regardless of any tendency of the envelope to adhere to the ink ribbon after the point of normal separation, or if they are bulged and tend to jam on internal portions of the mailing machine.

  • Patent number: 5820279
    Abstract: Apparatus for maintaining tension on a ribbon in a printer used for transferring an image, e.g., thermally, from a print head through the ribbon to a print medium. By maintaining ribbon tension and thus keeping the ribbon essentially without wrinkles, print quality is enhanced. This tension maintenance apparatus uses a pair of torqued reel subassemblies with the ribbon extending between and is of particular significance when used in conjunction with a label stock as a printer medium when the printer mechanism bidirectionally moves the label stock to assist removal of labels from its backing. These torqued reel assemblies are sufficiently loaded such that ribbon tension is maintained between these reel assemblies despite this bidirectional movement.

  • Patent number: 5779372
    Abstract: A printing system for transferring ink from an inked ribbon supplied from a ribbon roll having a tubular core with an inner surface onto a substrate. The system includes a rotatable locking cam hub having a reel hub with a first surface engageable with the inner surface of the ribbon roll, and an eccentric hub having a second surface engageable with the inner surface of the ribbon roll. The eccentric hub is rotatable relative to the reel hub to provide a variable diameter between the first surface of the reel hub and the second surface of the eccentric hub. The diameter of the locking cam hub may be reduced by rotating the eccentric hub relative to the reel hub to permit disposal of the ribbon roll tubular core about locking cam hub, and the diameter of the locking cam hub may be increased by rotating the eccentric hub relative to the reel hub to engageably retain the inner surface of the ribbon roll by the first surface of the reel hub and the second surface of the eccentric hub.
