  • Patent number: 6471334
    Abstract: An apparatus for horizontally loading and unloading an ink-jet print cartridge from a carriage in a printer. The apparatus includes a generally rectangular print cartridge, an elongate supporting lip located on a side wall of the print cartridge, a carriage body, a chute mounted on the carriage for receiving the print cartridge, and a generally horizontal rail on a side wall of the chute for guiding the print cartridge into the carriage. In operation, the apparatus horizontally loads a print cartridge into a carriage by translating the print cartridge horizontally forward into a carriage, engaging a lip on the print cartridge with a guide rail on the carriage, sliding the print cartridge up and over a datum on the carriage with the guide rail and latching the print cartridge in the carriage.

  • Patent number: 6435662
    Abstract: An ink-jet print cartridge is especially configured for loading and unloading into and from an inkjet print cartridge by use of substantially only horizontal translational movements relative to a carriage of the printer. The apparatus includes a generally rectangular prismatic print cartridge having its major axis of elongation disposed horizontally. The print cartridge includes a pair of outwardly extending elongate horizontal supporting lips located one on each of the opposite side walls of the print cartridge, a carriage body, a chute mounted on the carriage for receiving the print cartridge, and a generally horizontal guide rail on each of the pair of side walls of the chute. The guide rails guide the print cartridge into the carriage by supportingly engaging the lips.

  • Patent number: 6340256
    Abstract: The present invention provides a low profile stackable Internet appliance printer for use with a television receiver and monitor and responsive to commands from a remote device for printing user desired information. The printer has a box like rectangular shaped housing conforming in size to that of conventional electronic audio video components such as cable boxes, DVD players, amplifiers, video tapes and the like to facilitate the stacking of the printer with such other components. A base member supports in a front portion of the printer a printbar and associated printheads to provide the user with easy printhead head access. The base member has an open bottom for receiving a removable combination input/output tray cassette. Upon removal of the combination input/output tray cassette, front user access is made available for the purposes of removing a paper jam should one occur.

  • Patent number: 6328415
    Abstract: A displaceable print cartridge chute for an inkjet printer. The chute holding the print cartridges is displaceable from the carriage that sweeps the cartridges relative to the media during printing. The chute can be moved from a printing position engaged with the carriage to a service position adjacent a side of the printer so as to facilitate installation and removal of the cartridges through the side rather than the top of the printer. Because cartridges are serviced through the side, a printer incorporating the displaceable print cartridge chute can be stacked with other electronic equipment.

  • Patent number: 6222892
    Abstract: A synchronization message detecting unit detects a synchronization message from a line signal received from a line terminating unit. A synchronization message processing unit controls whether or not to select a clock reference received from the line as an active reference according to a quality level represented by the synchronization message. In this case, when an installed state detecting unit has determined that the synchronization message detecting unit has not been installed, the synchronization message processing unit does not select a clock reference corresponding to the synchronization message detected by the synchronization message detecting unit determined as a non-installed unit as the active reference.
