  • Patent number: 5887988
    Abstract: A printer with paper stacker activation. A platen is mounted on the drive roller for both rotation and translation. When fully to the right end of its travel, the platen is engaged with rotation stops which position the platen a fixed distance from the print cartridge, and disengaged from the roller, which can rotate for paper advancement during printing. When translated to the left, the platen is disengaged from the rotation stops and allowed to rotate. A clockwise rotation of the drive roller brings a roller shoulder into contact with a platen tab, urging the platen downwardly, clearing the way for the paper to fall into the output tray. Platen translation from right to left is driven by the carriage. A flag and a key are mounted on the roller, and engage the platen by the pen carriage. The key has a friction pinch on the roller, such that a torque is produced when the roller turns. The flag is adjacent the key, and the torque produced by the key urges rotation of the flag.
    Type: Grant

  • Patent number: 5746528
    Abstract: A hard copy apparatus with a print media telescoping tray system is disclosed. The telescoping tray system consists of an output tray, a paper tray, and an output tray position detector. The trays are constrained to translate in one line of motion, a substantially planar path into and out of the front of the apparatus, by nesting the paper tray within the output tray and guiding the trays along the line of motion. The trays telescope in a relatively small vertical opening below the paper feed drive mechanism of the apparatus. The telescoping tray system enables two modes of printing operation by providing a paper output path when in the output tray closed mode and by providing a full tray where printed sheets can be stacked during a multi-sheet or batch print job in an output tray open mode.
