Record Receivers And/or Driving Means Therefor Patents (Class 346/134)
  • Patent number: 6554415
    Abstract: A hardcopy apparatus includes a media drive roller and an independent media holddown unit. Such holddown unit includes a platen, on which a print zone is defined, and a vacuum source for generating a negative pressure for holding at least a portion of a medium substantially flat on the print zone. The platen is extending towards, and partially overlapping, the drive roller. In addition, a method for holding a medium to be printed on substantially flat over a print zone of a hardcopy apparatus includes indexing the medium over the print zone, generating a negative pressure capable of holding a portion of the medium flat on the print zone, extending the negative pressure generated to the print zone, to achieve a substantially uniform holding force over the print zone.

    Abstract: A media transport system for transporting a media sheet in a marking device includes an entrance drive assembly, an exit drive assembly and a vacuum generator that applies a vacuum force to the media sheet to form a wide, flat printing zone. The entrance drive assembly receives and transports the media sheet in a process direction by contacting top and bottom surfaces of the media sheet, thereby exerting an entrance drive force on the media sheet. The exit drive assembly receives and transports the media sheet by contacting the top and bottom surfaces of the media sheet, thereby exerting an exit drive force on the media sheet. The vacuum force is applied to the media sheet in an area of the media sheet between the entrance drive assembly and the exit drive assembly. The vacuum force on the media sheet acts in a vacuum force direction substantially normal to the process direction.

  • Patent number: 5986686
    Abstract: A thermal printing apparatus for printing graphic images on sheet material, such as a vinyl sheet, utilizes a platen drive to move the sheet material between a roller platen and thermal print head. The thermal print head presses the sheet material into engagement with the roller platen along a linear zone of contact, and a drive motor is drivingly connected to the roller platen through a series of drive gears to rotatably drive the roller platen, and in turn move the sheet material between the platen and print head. A pair of registration sprockets are mounted on opposite ends of a common sprocket shaft, and engage corresponding feed holes formed in the marginal edges of the sheet material. The registration sprockets guide and steer the sheet material as it is driven between the roller platen and the print head, and substantially prevent buckling or like distortion of the sheet material.

    Abstract: An ink printer for printing on a recording medium using a liquid ink includes at least one rotatable member arranged in a region of a transport path of the recording medium. The rotatable member is located so as to be capable of contacting liquid ink for forming an image on the recording medium. The rotatable member includes a radially outermost perimeter portion which serves as a recording medium contacting peripheral surface. The outermost perimeter portion has an outermost edge which is continuously contactable with the printing surface of the recording medium. The bonding force with respect to the ink on the outermost edge is less than the sum of a bonding force between the recording medium and the ink on a surface of the recording medium, and the cohesive force of the ink itself on the surface of the recording medium. As a result adherence of the ink to the contacting peripheral surface of the at least one rotatable member is prevented.

  • Patent number: 5594486
    Abstract: The present invention provides a recording apparatus comprising convey means for conveying a sheet in a predetermined convey direction, a pair of rollers arranged downstream of the coney means in the convey direction for conveying the sheet in the convey direction or in a reverse direction by rotation in a forward direction or in a reverse direction, and control means for controlling the convey means and the pair of rollers. The control means controls these elements in such a manner that, after a sheet conveyed by the convey means is conveyed in the convey direction by a predetermined amount by the pair of rollers, the pair of rollers are rotated in the reverse direction while applying a conveying force in the convey direction to the sheet using the convey means, thereby conveying the sheet in the reverse direction until the sheet passes through a nip formed between the pair of rollers.

  • Patent number: 5568166
    Abstract: A recording apparatus having a housing, a paper cassette insertable into the housing to a loaded position at which paper sheets may be advanced from the cassette to a paper feed path in the housing, the cassette being removable from the housing. A sheet handling device is supported by the housing to be located in the paper feed path downstream from the loaded position of the cassette. The sheet handling device includes a rotatable feed component, a pressing component to retain a sheet of paper against the feed component, and a movable holder to support the pressing component for movement between an active position against the feed component and a retracted position spaced from the feed component. Cooperating components on the paper cassette and the holder move the holder to locate and retain the pressing component in the active position upon insertion of the cassette to the loaded position and move the pressing component to the retracted position upon removal of the cassette from the housing.

  • Patent number: 5531436
    Abstract: A sheet transport apparatus includes a device for generating an electrostatic attraction force for attracting a sheet member to a surface of a transport belt disposed close to another surface of the transport belt opposite to the surface that contacts the sheet member. The apparatus is arranged to reduce a drive load on the transport belt caused by the electrostatic attraction force. To achieve this effect, at least one of a surface of the electrostatic attraction force generating device contacting the transport belt and a surface of the transport belt contacting the electrostatic attraction force generating device is roughened. Alternatively, an electrostatic attraction force generated at at least one particular portion of the transport belt by the electrostatic attraction force generating device is smaller than an electrostatic attraction force generated at another portion of the transport belt.

  • Patent number: 5488407
    Abstract: A recording head having a plurality of recording elements arranged thereon is moved in a different direction than a direction of arrangement to make record scan and a recording sheet is fed by a distance corresponding to a recording width of the recording head for each scan. The record scan (main scan) and the sheet feed (sub-scan) are repeated to record received image data on the recording sheet. The feed amount of the recording sheet is counted, and the data is sent to a recording unit until the count reaches a predetermined count, that is, the data a predetermined amount before a trailing edge of the recording sheet is sent, without synchronization with the operation of the recording unit.
