Paper output unit for ink-jet printer

A paper output unit for an ink-jet printer having a feed roller, said paper output unit comprising:

• a friction star wheel positioned to guide sheets of print media;
• a delivery roller positioned in a spatial relation to said friction star wheel to eject a sheet of paper upon completion of printing;
• a mobile body having support panels at each end thereof for supporting said delivery roller;
• and
• a guide bracket mounted on a base of the printer for directing movement of the mobile body, said mobile body being responsive to rotation of said feed roller in a direction opposite to a paper transport direction for shifting said delivery roller away from said friction star wheel to align a next sheet of print media along a surface of the delivery roller before the feeding of the next sheet of print media into the printer and, alternatively, for bringing said delivery roller into direct contact with said friction star wheel to eject the sheet of print media from the printer in response to said feed roller rotating in said paper transport direction.

• a guide bracket mounted on a base of the printer for directing movement of the mobile body;
• a plunger shaft connected to the mobile body;
• and
• a driving unit connected to said plunger shaft for controlling movement of said mobile body to thereby shift said delivery roller in spatial relation to said friction star wheel in accordance with rotation of the feed roller to feed the sheet of print media into the printer, said driving unit shifting said delivery roller toward said friction star wheel and into direct contact therewith for ejecting the sheet of print media from the printer in response to said feed roller rotating in a paper transport direction and, alternatively, shifting said delivery roller away from said friction star wheel in response to said feed roller rotating in a direction opposite to said paper transport direction to align a next sheet of print media in position for printing.

• a delivery roller positioned in a spatial relation to said friction star wheel to eject a sheet of paper upon completion of printing;
• a plunger shaft;
• a roller bracket having a pivot, a first end for supporting said delivery roller, and a second end connected to said plunger shaft, said roller bracket rotating about said pivot to bring said delivery roller into direct contact with said friction star wheel for ejecting the sheet of print media from the printer in response to the feed roller rotating in a paper transport direction and, alternatively, to shift said delivery roller away from said friction star wheel in response to said feed roller rotating in a direction opposite to said paper transport direction to align a next sheet of print media in position for printing;
• and
• a driving unit connected to said plunger shaft for controlling movement of said roller bracket to thereby shift said delivery roller in spatial relation to said friction star wheel in accordance with rotation of said feed roller.
